+===================
+Devicetree (DT) ABI
+===================
+
+I. Regarding stable bindings/ABI, we quote from the 2013 ARM mini-summit
+ summary document:
+
+ "That still leaves the question of, what does a stable binding look
+ like? Certainly a stable binding means that a newer kernel will not
+ break on an older device tree, but that doesn't mean the binding is
+ frozen for all time. Grant said there are ways to change bindings that
+ don't result in breakage. For instance, if a new property is added,
+ then default to the previous behaviour if it is missing. If a binding
+ truly needs an incompatible change, then change the compatible string
+ at the same time. The driver can bind against both the old and the
+ new. These guidelines aren't new, but they desperately need to be
+ documented."
+
+II. General binding rules
+
+ 1) Maintainers, don't let perfect be the enemy of good. Don't hold up a
+ binding because it isn't perfect.
+
+ 2) Use specific compatible strings so that if we need to add a feature (DMA)
+ in the future, we can create a new compatible string. See I.
+
+ 3) Bindings can be augmented, but the driver shouldn't break when given
+ the old binding. ie. add additional properties, but don't change the
+ meaning of an existing property. For drivers, default to the original
+ behaviour when a newly added property is missing.
+
+ 4) Don't submit bindings for staging or unstable. That will be decided by
+ the devicetree maintainers *after* discussion on the mailinglist.
+
+III. Notes
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.

+ ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon".
+
+ This currently includes devices based on the "M1" SoC:
+
+ - Mac mini (M1, 2020)
+ - MacBook Pro (13-inch, M1, 2020)
+ - MacBook Air (M1, 2020)
+ - iMac (24-inch, M1, 2021)
+
+ Devices based on the "M2" SoC:
+
+ - MacBook Air (M2, 2022)
+ - MacBook Pro (13-inch, M2, 2022)
+ - Mac mini (M2, 2023)
+
+ And devices based on the "M1 Pro", "M1 Max" and "M1 Ultra" SoCs:
+
+ - MacBook Pro (14-inch, M1 Pro, 2021)
+ - MacBook Pro (14-inch, M1 Max, 2021)
+ - MacBook Pro (16-inch, M1 Pro, 2021)
+ - MacBook Pro (16-inch, M1 Max, 2021)
+ - Mac Studio (M1 Max, 2022)
+ - Mac Studio (M1 Ultra, 2022)
+
+ The compatible property should follow this format:
+
+ compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform";
+
+ <targettype> represents the board/device and comes from the `target-type`
+ property of the root node of the Apple Device Tree, lowercased. It can be
+ queried on macOS using the following command:
+
+ $ ioreg -d2 -l | grep target-type
+
+ <socid> is the lowercased SoC ID. Apple uses at least *five* different
+ names for their SoCs:
+
+ - Marketing name ("M1")
+ - Internal name ("H13G")
+ - Codename ("Tonga")
+ - SoC ID ("T8103")
+ - Package/IC part number ("APL1102")
+
+ Devicetrees should use the lowercased SoC ID, to avoid confusion if
+ multiple SoCs share the same marketing name. This can be obtained from
+ the `compatible` property of the arm-io node of the Apple Device Tree,
+ which can be queried as follows on macOS:
+
+ $ ioreg -n arm-io | grep compatible

+title: ARM Coresight Cross Trigger Interface (CTI) device.
+
+description: |
+ The CoreSight Embedded Cross Trigger (ECT) consists of CTI devices connected
+ to one or more CoreSight components and/or a CPU, with CTIs interconnected in
+ a star topology via the Cross Trigger Matrix (CTM), which is not programmable.
+ The ECT components are not part of the trace generation data path and are thus
+ not part of the CoreSight graph.
+
+ The CTI component properties define the connections between the individual
+ CTI and the components it is directly connected to, consisting of input and
+ output hardware trigger signals. CTIs can have a maximum number of input and
+ output hardware trigger signals (8 each for v1 CTI, 32 each for v2 CTI). The
+ number is defined at design time, the maximum of each defined in the DEVID
+ register.
+
+ CTIs are interconnected in a star topology via the CTM, using a number of
+ programmable channels, usually 4, but again implementation defined and
+ described in the DEVID register. The star topology is not required to be
+ described in the bindings as the actual connections are software
+ programmable.
+
+ In general the connections between CTI and components via the trigger signals
+ are implementation defined, except when the CTI is connected to an ARM v8
+ architecture core and optional ETM.
+
+ In this case the ARM v8 architecture defines the required signal connections
+ between CTI and the CPU core and ETM if present. In the case of a v8
+ architecturally connected CTI an additional compatible string is used to
+ indicate this feature (arm,coresight-cti-v8-arch).
+
+ When CTI trigger connection information is unavailable then a minimal driver
+ binding can be declared with no explicit trigger signals. This will result
+ the driver detecting the maximum available triggers and channels from the
+ DEVID register and make them all available for use as a single default
+ connection. Any user / client application will require additional information
+ on the connections between the CTI and other components for correct operation.
+ This information might be found by enabling the Integration Test registers in
+ the driver (set CONFIG_CORESIGHT_CTI_INTEGRATION_TEST in Kernel
+ configuration). These registers may be used to explore the trigger connections
+ between CTI and other CoreSight components.
+
+ Certain triggers between CoreSight devices and the CTI have specific types
+ and usages. These can be defined along with the signal indexes with the
+ constants defined in <dt-bindings/arm/coresight-cti-dt.h>
+
+ For example a CTI connected to a core will usually have a DBGREQ signal. This
+ is defined in the binding as type PE_EDBGREQ. These types will appear in an
+ optional array alongside the signal indexes. Omitting types will default all
+ signals to GEN_IO.
+
+ Note that some hardware trigger signals can be connected to non-CoreSight
+ components (e.g. UART etc) depending on hardware implementation.

+description: |
+ CoreSight components are compliant with the ARM CoreSight architecture
+ specification and can be connected in various topologies to suit a particular
+ SoCs tracing needs. These trace components can generally be classified as
+ sinks, links and sources. Trace data produced by one or more sources flows
+ through the intermediate links connecting the source to the currently selected
+ sink.
+
+ The CoreSight Trace Port Interface Unit captures trace data from the trace bus
+ and outputs it to an external trace port.

+ Arm Embedded Trace Extension(ETE) is a per CPU trace component that

+ components (e.g, TMC-ETR) or other means (e.g, using a per CPU buffer
+ Arm Trace Buffer Extension (TRBE)). Since the ETE can be connected to
+ legacy CoreSight components, a node must be listed per instance, along

+
+description: |+
+ ARM's Versatile Express platform were built as reference designs for exploring
+ multicore Cortex-A class systems. The Versatile Express family contains both
+ 32 bit (Aarch32) and 64 bit (Aarch64) systems.
+
+ The board consist of a motherboard and one or more daughterboards (tiles). The
+ motherboard provides a set of peripherals. Processor and RAM "live" on the
+ tiles.
+
+ The motherboard and each core tile should be described by a separate Device
+ Tree source file, with the tile's description including the motherboard file
+ using an include directive. As the motherboard can be initialized in one of
+ two different configurations ("memory maps"), care must be taken to include
+ the correct one.
+
+ When a new generation of boards were introduced under the name "Juno", these
+ shared to many common characteristics with the Versatile Express that the
+ "arm,vexpress" compatible was retained in the root node, and these are
+ included in this binding schema as well.

+Broadcom BCM63138 DSL System-on-a-Chip device tree bindings
+-----------------------------------------------------------
+
+Boards compatible with the BCM63138 DSL System-on-a-Chip should have the
+following properties:
+
+Required root node property:
+
+compatible: should be "brcm,bcm63138"
+
+An optional Boot lookup table Device Tree node is required for secondary CPU
+initialization as well as a 'resets' phandle to the correct PMB controller as
+defined in reset/brcm,bcm63138-pmb.txt for this secondary CPU, and an
+'enable-method' property.
+
+Required properties for the Boot lookup table node:
+- compatible: should be "brcm,bcm63138-bootlut"
+- reg: register base address and length for the Boot Lookup table
+
+Optional properties for the primary CPU node:
+- enable-method: should be "brcm,bcm63138"
+
+Optional properties for the secondary CPU node:
+- enable-method: should be "brcm,bcm63138"
+- resets: phandle to the relevant PMB controller, one integer indicating the internal
+ bus number, and a second integer indicating the address of the CPU in the PMB
+ internal bus number.
+
+Example:
+
+ cpus {
+ cpu@0 {
+ compatible = "arm,cortex-a9";
+ reg = <0>;
+ ...
+ enable-method = "brcm,bcm63138";
+ };
+
+ cpu@1 {
+ compatible = "arm,cortex-a9";
+ reg = <1>;
+ ...
+ enable-method = "brcm,bcm63138";
+ resets = <&pmb0 4 1>;
+ };
+ };
+
+ bootlut: bootlut@8000 {
+ compatible = "brcm,bcm63138-bootlut";
+ reg = <0x8000 0x50>;
+ };
+
+=======
+reboot
+------
+Two nodes are required for software reboot: a timer node and a syscon-reboot node.
+
+Timer node:
+
+- compatible: Must be "brcm,bcm6328-timer", "syscon"
+- reg: Register base address and length
+
+Syscon reboot node:
+
+See Documentation/devicetree/bindings/power/reset/syscon-reboot.yaml for the
+detailed list of properties, the two values defined below are specific to the
+BCM6328-style timer:
+
+- offset: Should be 0x34 to denote the offset of the TIMER_WD_TIMER_RESET register
+ from the beginning of the TIMER block
+- mask: Should be 1 for the SoftRst bit.
+
+Example:
+
+ timer: timer@80 {
+ compatible = "brcm,bcm6328-timer", "syscon";
+ reg = <0x80 0x3c>;
+ };
+
+ reboot {
+ compatible = "syscon-reboot";
+ regmap = <&timer>;
+ offset = <0x34>;
+ mask = <0x1>;
+ };

+ARM Broadcom STB platforms Device Tree Bindings
+-----------------------------------------------
+Boards with Broadcom Brahma15 ARM-based BCMxxxx (generally BCM7xxx variants)
+SoC shall have the following DT organization:
+
+Required root node properties:
+ - compatible: "brcm,bcm<chip_id>", "brcm,brcmstb"
+
+example:
+/ {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ model = "Broadcom STB (bcm7445)";
+ compatible = "brcm,bcm7445", "brcm,brcmstb";
+
+Further, syscon nodes that map platform-specific registers used for general
+system control is required:
+
+ - compatible: "brcm,bcm<chip_id>-sun-top-ctrl", "syscon"
+ - compatible: "brcm,bcm<chip_id>-cpu-biu-ctrl",
+ "brcm,brcmstb-cpu-biu-ctrl",
+ "syscon"
+ - compatible: "brcm,bcm<chip_id>-hif-continuation", "syscon"
+
+cpu-biu-ctrl node
+-------------------
+SoCs with Broadcom Brahma15 ARM-based and Brahma53 ARM64-based CPUs have a
+specific Bus Interface Unit (BIU) block which controls and interfaces the CPU
+complex to the different Memory Controller Ports (MCP), one per memory
+controller (MEMC). This BIU block offers a feature called Write Pairing which
+consists in collapsing two adjacent cache lines into a single (bursted) write
+transaction towards the memory controller (MEMC) to maximize write bandwidth.
+
+Required properties:
+
+ - compatible: must be "brcm,bcm7445-cpu-biu-ctrl", "brcm,brcmstb-cpu-biu-ctrl", "syscon"
+
+Optional properties:
+
+ - brcm,write-pairing:
+ Boolean property, which when present indicates that the chip
+ supports write-pairing.
+
+example:
+ rdb {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "simple-bus";
+ ranges = <0 0x00 0xf0000000 0x1000000>;
+
+ sun_top_ctrl: syscon@404000 {
+ compatible = "brcm,bcm7445-sun-top-ctrl", "syscon";
+ reg = <0x404000 0x51c>;
+ };
+
+ hif_cpubiuctrl: syscon@3e2400 {
+ compatible = "brcm,bcm7445-cpu-biu-ctrl", "brcm,brcmstb-cpu-biu-ctrl", "syscon";
+ reg = <0x3e2400 0x5b4>;
+ brcm,write-pairing;
+ };
+
+ hif_continuation: syscon@452000 {
+ compatible = "brcm,bcm7445-hif-continuation", "syscon";
+ reg = <0x452000 0x100>;
+ };
+ };
+
+Nodes that allow for support of SMP initialization and reboot are required:
+
+smpboot
+-------
+Required properties:
+
+ - compatible
+ The string "brcm,brcmstb-smpboot".
+
+ - syscon-cpu
+ A phandle / integer array property which lets the BSP know the location
+ of certain CPU power-on registers.
+
+ The layout of the property is as follows:
+ o a phandle to the "hif_cpubiuctrl" syscon node
+ o offset to the base CPU power zone register
+ o offset to the base CPU reset register
+
+ - syscon-cont
+ A phandle pointing to the syscon node which describes the CPU boot
+ continuation registers.
+ o a phandle to the "hif_continuation" syscon node
+
+example:
+ smpboot {
+ compatible = "brcm,brcmstb-smpboot";
+ syscon-cpu = <&hif_cpubiuctrl 0x88 0x178>;
+ syscon-cont = <&hif_continuation>;
+ };
+
+reboot
+-------
+Required properties
+
+ - compatible
+ The string property "brcm,brcmstb-reboot" for 40nm/28nm chips with
+ the new SYS_CTRL interface, or "brcm,bcm7038-reboot" for 65nm
+ chips with the old SUN_TOP_CTRL interface.
+
+ - syscon
+ A phandle / integer array that points to the syscon node which describes
+ the general system reset registers.
+ o a phandle to "sun_top_ctrl"
+ o offset to the "reset source enable" register
+ o offset to the "software master reset" register
+
+example:
+ reboot {
+ compatible = "brcm,brcmstb-reboot";
+ syscon = <&sun_top_ctrl 0x304 0x308>;
+ };
+
+
+
+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-aon-ctrl"
+- reg : the register start and length for the AON CTRL block
+
+Example:
+
+aon-ctrl@410000 {
+ compatible = "brcm,brcmstb-aon-ctrl";
+ reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY). See
+the example device tree snippet below.
+
+== MEMC (MEMory Controller)
+
+Represents a single memory controller instance.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-memc" and "simple-bus"
+
+Should contain subnodes for any of the following relevant hardware resources:
+
+== DDR PHY control
+
+Control registers for this memory controller's DDR PHY.
+
+Required properties:
+- compatible : should contain one of these
+ "brcm,brcmstb-ddr-phy-v71.1"
+ "brcm,brcmstb-ddr-phy-v72.0"
+ "brcm,brcmstb-ddr-phy-v225.1"
+ "brcm,brcmstb-ddr-phy-v240.1"
+ "brcm,brcmstb-ddr-phy-v240.2"
+
+- reg : the DDR PHY register range
+
+== DDR SHIMPHY
+
+Control registers for this memory controller's DDR SHIMPHY.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-ddr-shimphy-v1.0"
+- reg : the DDR SHIMPHY register range
+
+== MEMC DDR control
+
+Sequencer DRAM parameters and control registers. Used for Self-Refresh
+Power-Down (SRPD), among other things.
+
+See Documentation/devicetree/bindings/memory-controllers/brcm,brcmstb-memc-ddr.yaml for a
+full list of supported compatible strings and properties.
+
+Example:
+
+memory_controllers {
+ ranges;
+ compatible = "simple-bus";
+
+ memc@0 {
+ compatible = "brcm,brcmstb-memc", "simple-bus";
+ ranges;
+

+ reg = <0xf1106000 0x21c>;
+ };
+
+ shimphy@f1108000 {
+ compatible = "brcm,brcmstb-ddr-shimphy-v1.0";
+ reg = <0xf1108000 0xe4>;
+ };
+
+ memc-ddr@f1102000 {
+ reg = <0xf1102000 0x800>;
+ compatible = "brcm,brcmstb-memc-ddr";
+ };
+ };
+
+ memc@1 {
+ compatible = "brcm,brcmstb-memc", "simple-bus";
+ ranges;
+
+ ddr-phy@f1186000 {

+Secondary CPU enable-method "al,alpine-smp" binding
+========================================================
+
+This document describes the "al,alpine-smp" method for
+enabling secondary CPUs. To apply to all CPUs, a single
+"al,alpine-smp" enable method should be defined in the
+"cpus" node.
+
+Enable method name: "al,alpine-smp"
+Compatible machines: "al,alpine"
+Compatible CPUs: "arm,cortex-a15"
+Related properties: (none)
+
+Note:
+This enable method requires valid nodes compatible with
+"al,alpine-cpu-resume" and "al,alpine-nb-service".
+
+
+* Alpine CPU resume registers
+
+The CPU resume register are used to define required resume address after
+reset.
+
+Properties:
+- compatible : Should contain "al,alpine-cpu-resume".
+- reg : Offset and length of the register set for the device
+
+
+* Alpine System-Fabric Service Registers
+
+The System-Fabric Service Registers allow various operation on CPU and
+system fabric, like powering CPUs off.
+
+Properties:
+- compatible : Should contain "al,alpine-sysfabric-service" and "syscon".
+- reg : Offset and length of the register set for the device
+
+
+Example:
+
+cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;

+description: |+
+ The device tree allows to describe the layout of CPUs in a system through
+ the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+ defining properties for every cpu.
+
+ Bindings for CPU nodes follow the Devicetree Specification, available from:
+
+ https://www.devicetree.org/specifications/
+
+ with updates for 32-bit and 64-bit ARM systems provided in this document.
+
+ ================================
+ Convention used in this document
+ ================================
+
+ This document follows the conventions described in the Devicetree
+ Specification, with the addition:
+
+ - square brackets define bitfields, eg reg[7:0] value of the bitfield in
+ the reg property contained in bits 7 down to 0
+
+ =====================================
+ cpus and cpu node bindings definition
+ =====================================
+
+ The ARM architecture, in accordance with the Devicetree Specification,
+ requires the cpus and cpu nodes to be present and contain the properties
+ described below.
+
+properties:
+ reg:
+ maxItems: 1
+ description: |
+ Usage and definition depend on ARM architecture version and
+ configuration:
+
+ On uniprocessor ARM architectures previous to v7
+ this property is required and must be set to 0.
+
+ On ARM 11 MPcore based systems this property is
+ required and matches the CPUID[11:0] register bits.
+
+ Bits [11:0] in the reg cell must be set to
+ bits [11:0] in CPU ID register.
+
+ All other bits in the reg cell must be set to 0.
+
+ On 32-bit ARM v7 or later systems this property is
+ required and matches the CPU MPIDR[23:0] register
+ bits.
+
+ Bits [23:0] in the reg cell must be set to
+ bits [23:0] in MPIDR.
+
+ All other bits in the reg cell must be set to 0.
+
+ On ARM v8 64-bit systems this property is required
+ and matches the MPIDR_EL1 register affinity bits.
+
+ * If cpus node's #address-cells property is set to 2
+
+ The first reg cell bits [7:0] must be set to
+ bits [39:32] of MPIDR_EL1.
+
+ The second reg cell bits [23:0] must be set to
+ bits [23:0] of MPIDR_EL1.
+
+ * If cpus node's #address-cells property is set to 1
+
+ The reg cell bits [23:0] must be set to bits [23:0]
+ of MPIDR_EL1.
+
+ All other bits in the reg cells must be set to 0.

+* Software Delegated Exception Interface (SDEI)
+
+Firmware implementing the SDEI functions described in ARM document number
+ARM DEN 0054A ("Software Delegated Exception Interface") can be used by
+Linux to receive notification of events such as those generated by
+firmware-first error handling, or from an IRQ that has been promoted to
+a firmware-assisted NMI.
+
+The interface provides a number of API functions for registering callbacks
+and enabling/disabling events. Functions are invoked by trapping to the
+privilege level of the SDEI firmware (specified as part of the binding
+below) and passing arguments in a manner specified by the "SMC Calling
+Convention (ARM DEN 0028B):
+
+ r0 => 32-bit Function ID / return value
+ {r1 - r3} => Parameters
+
+Note that the immediate field of the trapping instruction must be set
+to #0.
+
+The SDEI_EVENT_REGISTER function registers a callback in the kernel
+text to handle the specified event number.
+
+The sdei node should be a child node of '/firmware' and have required
+properties:
+
+ - compatible : should contain:
+ * "arm,sdei-1.0" : For implementations complying to SDEI version 1.x.
+
+ - method : The method of calling the SDEI firmware. Permitted
+ values are:
+ * "smc" : SMC #0, with the register assignments specified in this
+ binding.
+ * "hvc" : HVC #0, with the register assignments specified in this
+ binding.
+Example:
+ firmware {
+ sdei {
+ compatible = "arm,sdei-1.0";
+ method = "smc";
+ };
+ };

+Freescale Vybrid Miscellaneous System Control - Interrupt Router
+
+The MSCM IP contains multiple sub modules, this binding describes the second
+block of registers which control the interrupt router. The interrupt router
+allows to configure the recipient of each peripheral interrupt. Furthermore
+it controls the directed processor interrupts. The module is available in all
+Vybrid SoC's but is only really useful in dual core configurations (VF6xx
+which comes with a Cortex-A5/Cortex-M4 combination).
+
+Required properties:
+- compatible: "fsl,vf610-mscm-ir"
+- reg: the register range of the MSCM Interrupt Router
+- fsl,cpucfg: The handle to the MSCM CPU configuration node, required
+ to get the current CPU ID
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells: Two cells, interrupt number and cells.
+ The hardware interrupt number according to interrupt
+ assignment of the interrupt router is required.
+ Flags get passed only when using GIC as parent. Flags
+ encoding as documented by the GIC bindings.
+
+Example:
+ mscm_ir: interrupt-controller@40001800 {
+ compatible = "fsl,vf610-mscm-ir";
+ reg = <0x40001800 0x400>;

+
+description: |
+ The Gemini SoC is the project name for an ARMv4 FA525-based SoC originally
+ produced by Storlink Semiconductor around 2005. The company was renamed
+ later renamed Storm Semiconductor. The chip product name is Storlink SL3516.
+ It was derived from earlier products from Storm named SL3316 (Centroid) and
+ SL3512 (Bulverde).
+
+ Storm Semiconductor was acquired by Cortina Systems in 2008 and the SoC was
+ produced and used for NAS and similar usecases. In 2014 Cortina Systems was
+ in turn acquired by Inphi, who seem to have discontinued this product family.
+
+ Many of the IP blocks used in the SoC comes from Faraday Technology.

+description: |
+ The Hisilicon system controller is used on many Hisilicon boards, it can be
+ used to assist the slave core startup, reboot the system, etc.
+
+ There are some variants of the Hisilicon system controller, such as HiP01,
+ Hi3519, Hi6220 system controller, each of them is mostly compatible with the
+ Hisilicon system controller, but some same registers located at different
+ offset. In addition, the HiP01 system controller has some specific control
+ registers for HIP01 SoC family, such as slave core boot.
+
+ The compatible names of each system controller are as follows:
+ Hisilicon system controller --> hisilicon,sysctrl
+ HiP01 system controller --> hisilicon,hip01-sysctrl
+ Hi6220 system controller --> hisilicon,hi6220-sysctrl

+
+ See http://processors.wiki.ti.com/index.php/TISCI for protocol definition.

+Marvell Armada AP80x System Controller
+======================================
+
+The AP806/AP807 is one of the two core HW blocks of the Marvell Armada
+7K/8K/931x SoCs. It contains system controllers, which provide several
+registers giving access to numerous features: clocks, pin-muxing and
+many other SoC configuration items. This DT binding allows to describe
+these system controllers.
+
+For the top level node:
+ - compatible: must be: "syscon", "simple-mfd";
+ - reg: register area of the AP80x system controller
+
+SYSTEM CONTROLLER 0
+===================
+
+Clocks:
+-------
+
+
+The Device Tree node representing the AP806/AP807 system controller
+provides a number of clocks:
+
+ - 0: reference clock of CPU cluster 0
+ - 1: reference clock of CPU cluster 1
+ - 2: fixed PLL at 1200 Mhz
+ - 3: MSS clock, derived from the fixed PLL
+
+Required properties:
+
+ - compatible: must be one of:
+ * "marvell,ap806-clock"
+ * "marvell,ap807-clock"
+ - #clock-cells: must be set to 1
+
+Pinctrl:
+--------
+
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.
+
+Required properties:
+- compatible must be "marvell,ap806-pinctrl",
+
+Available mpp pins/groups and functions:

+GPIO:
+-----
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/gpio/gpio-mvebu.yaml.
+
+Required properties:
+
+- compatible: "marvell,armada-8k-gpio"
+
+- offset: offset address inside the syscon block
+
+Optional properties:
+
+- marvell,pwm-offset: offset address of PWM duration control registers inside
+ the syscon block
+
+Example:

+
+SYSTEM CONTROLLER 1
+===================
+
+Thermal:
+--------
+
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/thermal/thermal*.yaml
+
+The thermal IP can probe the temperature all around the processor. It
+may feature several channels, each of them wired to one sensor.
+
+It is possible to setup an overheat interrupt by giving at least one
+critical point to any subnode of the thermal-zone node.
+
+Required properties:
+- compatible: must be one of:
+ * marvell,armada-ap806-thermal
+- reg: register range associated with the thermal functions.
+
+Optional properties:
+- interrupts: overheat interrupt handle. Should point to line 18 of the
+ SEI irqchip. See interrupt-controller/interrupts.txt
+- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
+ to this IP and represents the channel ID. There is one sensor per
+ channel. O refers to the thermal IP internal channel, while positive
+ IDs refer to each CPU.
+
+Example:
+ap_syscon1: system-controller@6f8000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x6f8000 0x1000>;
+
+ ap_thermal: thermal-sensor@80 {
+ compatible = "marvell,armada-ap806-thermal";
+ reg = <0x80 0x10>;
+ interrupt-parent = <&sei>;
+ interrupts = <18>;
+ #thermal-sensor-cells = <1>;
+ };
+};
+
+Cluster clocks:
+---------------
+
+Device Tree Clock bindings for cluster clock of Marvell
+AP806/AP807. Each cluster contain up to 2 CPUs running at the same
+frequency.
+
+Required properties:

+ compatible = "marvell,armada-ap806-syscon1", "syscon", "simple-mfd";
+ reg = <0x6f8000 0x1000>;
+
+ cpu_clk: clock-cpu@278 {
+ compatible = "marvell,ap806-cpu-clock";
+ clocks = <&ap_clk 0>, <&ap_clk 1>;
+ #clock-cells = <1>;
+ reg = <0x278 0xa30>;
+ };

+Marvell Armada CP110 System Controller
+======================================
+
+The CP110 is one of the two core HW blocks of the Marvell Armada 7K/8K
+SoCs. It contains system controllers, which provide several registers
+giving access to numerous features: clocks, pin-muxing and many other
+SoC configuration items. This DT binding allows to describe these
+system controllers.
+
+For the top level node:
+ - compatible: must be: "syscon", "simple-mfd";
+ - reg: register area of the CP110 system controller
+
+SYSTEM CONTROLLER 0
+===================
+
+Clocks:
+-------
+
+The Device Tree node representing this System Controller 0 provides a
+number of clocks:
+
+ - a set of core clocks
+ - a set of gateable clocks
+
+Those clocks can be referenced by other Device Tree nodes using two
+cells:
+ - The first cell must be 0 or 1. 0 for the core clocks and 1 for the
+ gateable clocks.
+ - The second cell identifies the particular core clock or gateable
+ clocks.
+
+The following clocks are available:
+ - Core clocks
+ - 0 0 APLL
+ - 0 1 PPv2 core
+ - 0 2 EIP
+ - 0 3 Core
+ - 0 4 NAND core
+ - 0 5 SDIO core
+ - Gateable clocks
+ - 1 0 Audio
+ - 1 1 Comm Unit
+ - 1 2 NAND
+ - 1 3 PPv2
+ - 1 4 SDIO
+ - 1 5 MG Domain
+ - 1 6 MG Core
+ - 1 7 XOR1
+ - 1 8 XOR0
+ - 1 9 GOP DP
+ - 1 11 PCIe x1 0
+ - 1 12 PCIe x1 1
+ - 1 13 PCIe x4
+ - 1 14 PCIe / XOR
+ - 1 15 SATA
+ - 1 16 SATA USB
+ - 1 17 Main
+ - 1 18 SD/MMC/GOP
+ - 1 21 Slow IO (SPI, NOR, BootROM, I2C, UART)
+ - 1 22 USB3H0
+ - 1 23 USB3H1
+ - 1 24 USB3 Device
+ - 1 25 EIP150
+ - 1 26 EIP197
+
+Required properties:
+
+ - compatible: must be:
+ "marvell,cp110-clock"
+ - #clock-cells: must be set to 2
+
+Pinctrl:
+--------
+
+For common binding part and usage, refer to the file
+Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.
+
+Required properties:
+
+- compatible: "marvell,armada-7k-pinctrl", "marvell,armada-8k-cpm-pinctrl",
+ "marvell,armada-8k-cps-pinctrl" or "marvell,cp115-standalone-pinctrl"
+ depending on the specific variant of the SoC being used.

+SYSTEM CONTROLLER 1
+===================
+
+Thermal:
+--------
+
+The thermal IP can probe the temperature all around the processor. It
+may feature several channels, each of them wired to one sensor.
+
+It is possible to setup an overheat interrupt by giving at least one
+critical point to any subnode of the thermal-zone node.
+
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/thermal/thermal*.yaml
+
+Required properties:
+- compatible: must be one of:
+ * marvell,armada-cp110-thermal
+- reg: register range associated with the thermal functions.
+
+Optional properties:
+- interrupts-extended: overheat interrupt handle. Should point to
+ a line of the ICU-SEI irqchip (116 is what is usually used by the
+ firmware). The ICU-SEI will redirect towards interrupt line #37 of the
+ AP SEI which is shared across all CPs.
+ See interrupt-controller/interrupts.txt
+- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
+ to this IP and represents the channel ID. There is one sensor per
+ channel. O refers to the thermal IP internal channel.
+
+Example:
+CP110_LABEL(syscon1): system-controller@6f8000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x6f8000 0x1000>;
+
+ CP110_LABEL(thermal): thermal-sensor@70 {
+ compatible = "marvell,armada-cp110-thermal";
+ reg = <0x70 0x10>;
+ interrupts-extended = <&CP110_LABEL(icu_sei) 116 IRQ_TYPE_LEVEL_HIGH>;
+ #thermal-sensor-cells = <1>;
+ };

+MediaTek PCIESYS controller
+============================
+
+The MediaTek PCIESYS controller provides various clocks to the system.
+
+Required Properties:
+
+- compatible: Should be:
+ - "mediatek,mt7622-pciesys", "syscon"
+ - "mediatek,mt7629-pciesys", "syscon"
+- #clock-cells: Must be 1
+- #reset-cells: Must be 1
+
+The PCIESYS controller uses the common clk binding from
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+The available clocks are defined in dt-bindings/clock/mt*-clk.h.
+
+Example:
+
+pciesys: pciesys@1a100800 {
+ compatible = "mediatek,mt7622-pciesys", "syscon";
+ reg = <0 0x1a100800 0 0x1000>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;

+QCOM Idle States for cpuidle driver
+
+ARM provides idle-state node to define the cpuidle states, as defined in [1].
+cpuidle-qcom is the cpuidle driver for Qualcomm SoCs and uses these idle
+states. Idle states have different enter/exit latency and residency values.
+The idle states supported by the QCOM SoC are defined as -
+
+ * Standby
+ * Retention
+ * Standalone Power Collapse (Standalone PC or SPC)
+ * Power Collapse (PC)
+
+Standby: Standby does a little more in addition to architectural clock gating.
+When the WFI instruction is executed the ARM core would gate its internal
+clocks. In addition to gating the clocks, QCOM cpus use this instruction as a
+trigger to execute the SPM state machine. The SPM state machine waits for the
+interrupt to trigger the core back in to active. This triggers the cache
+hierarchy to enter standby states, when all cpus are idle. An interrupt brings
+the SPM state machine out of its wait, the next step is to ensure that the
+cache hierarchy is also out of standby, and then the cpu is allowed to resume
+execution. This state is defined as a generic ARM WFI state by the ARM cpuidle
+driver and is not defined in the DT. The SPM state machine should be
+configured to execute this state by default and after executing every other
+state below.
+
+Retention: Retention is a low power state where the core is clock gated and
+the memory and the registers associated with the core are retained. The
+voltage may be reduced to the minimum value needed to keep the processor
+registers active. The SPM should be configured to execute the retention
+sequence and would wait for interrupt, before restoring the cpu to execution
+state. Retention may have a slightly higher latency than Standby.
+
+Standalone PC: A cpu can power down and warmboot if there is a sufficient time
+between the time it enters idle and the next known wake up. SPC mode is used
+to indicate a core entering a power down state without consulting any other
+cpu or the system resources. This helps save power only on that core. The SPM
+sequence for this idle state is programmed to power down the supply to the
+core, wait for the interrupt, restore power to the core, and ensure the
+system state including cache hierarchy is ready before allowing core to
+resume. Applying power and resetting the core causes the core to warmboot
+back into Elevation Level (EL) which trampolines the control back to the
+kernel. Entering a power down state for the cpu, needs to be done by trapping
+into a EL. Failing to do so, would result in a crash enforced by the warm boot
+code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
+be flushed in s/w, before powering down the core.
+
+Power Collapse: This state is similar to the SPC mode, but distinguishes
+itself in that the cpu acknowledges and permits the SoC to enter deeper sleep
+modes. In a hierarchical power domain SoC, this means L2 and other caches can
+be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
+voltages reduced, provided all cpus enter this state. Since the span of low
+power modes possible at this state is vast, the exit latency and the residency
+of this low power mode would be considered high even though at a cpu level,
+this essentially is cpu power down. The SPM in this state also may handshake
+with the Resource power manager (RPM) processor in the SoC to indicate a
+complete application processor subsystem shut down.
+
+The idle-state for QCOM SoCs are distinguished by the compatible property of
+the idle-states device node.
+
+The devicetree representation of the idle state should be -
+
+Required properties:
+
+- compatible: Must be one of -
+ "qcom,idle-state-ret",

+SPM AVS Wrapper 2 (SAW2)
+
+The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
+Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable
+power-controller that transitions a piece of hardware (like a processor or
+subsystem) into and out of low power modes via a direct connection to
+the PMIC. It can also be wired up to interact with other processors in the
+system, notifying them when a low power state is entered or exited.
+
+Multiple revisions of the SAW hardware are supported using these Device Nodes.
+SAW2 revisions differ in the register offset and configuration data. Also, the
+same revision of the SAW in different SoCs may have different configuration
+data due the differences in hardware capabilities. Hence the SoC name, the
+version of the SAW hardware in that SoC and the distinction between cpu (big
+or Little) or cache, may be needed to uniquely identify the SAW register
+configuration and initialization data. The compatible string is used to
+indicate this parameter.
+
+PROPERTIES
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: Must have
+ "qcom,saw2"
+ A more specific value could be one of:

+ "qcom,msm8974-saw2-v2.1-cpu"
+ "qcom,apq8084-saw2-v2.1-cpu"
+
+- reg:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: the first element specifies the base address and size of
+ the register region. An optional second element specifies
+ the base address and size of the alias register region.

+Some socs have a large number of interrupts requests to service
+the needs of its many peripherals and subsystems. All of the
+interrupt lines from the subsystems are not needed at the same
+time, so they have to be muxed to the irq-controller appropriately.
+In such places a interrupt controllers are preceded by an CROSSBAR
+that provides flexibility in muxing the device requests to the controller
+inputs.
+
+Required properties:
+- compatible : Should be "ti,irq-crossbar"
+- reg: Base address and the size of the crossbar registers.
+- interrupt-controller: indicates that this block is an interrupt controller.
+- ti,max-irqs: Total number of irqs available at the parent interrupt controller.
+- ti,max-crossbar-sources: Maximum number of crossbar sources that can be routed.
+- ti,reg-size: Size of a individual register in bytes. Every individual
+ register is assumed to be of same size. Valid sizes are 1, 2, 4.
+- ti,irqs-reserved: List of the reserved irq lines that are not muxed using
+ crossbar. These interrupt lines are reserved in the soc,
+ so crossbar bar driver should not consider them as free
+ lines.
+
+Optional properties:
+- ti,irqs-skip: This is similar to "ti,irqs-reserved", but these are for

+ TPDAs are responsible for packetization and timestamping of data sets
+ utilizing the MIPI STPv2 packet protocol. Pulling data sets from one or
+ more attached TPDM and pushing the resultant (packetized) data out a
+ master ATB interface. Performing an arbitrated ATB interleaving (funneling)
+ task for free-flowing data from TPDM (i.e. CMB and DSB data set flows).
+
+ There is no strict binding between TPDM and TPDA. TPDA can have multiple
+ TPDMs connect to it. But There must be only one TPDA in the path from the
+ TPDM source to TMC sink. TPDM can directly connect to TPDA's inport or
+ connect to funnel which will connect to TPDA's inport.
+
+ We can use the commands are similar to the below to validate TPDMs.
+ Enable coresight sink first.

+ echo 1 > /sys/bus/coresight/devices/tpdm0/integration_test
+ echo 2 > /sys/bus/coresight/devices/tpdm0/integration_test
+
+ The test data will be collected in the coresight sink which is enabled.
+ If rwp register of the sink is keeping updating when do integration_test
+ (by cat tmc_etf0/mgmt/rwp), it means there is data generated from TPDM

+title: Trace, Profiling and Diagnostics Monitor - TPDM
+
+description: |
+ The TPDM or Monitor serves as data collection component for various dataset
+ types specified in the QPMDA spec. It covers Implementation defined ((ImplDef),
+ Basic Counts (BC), Tenure Counts (TC), Continuous Multi-Bit (CMB), and Discrete
+ Single Bit (DSB). It performs data collection in the data producing clock
+ domain and transfers it to the data collection time domain, generally ATB
+ clock domain.
+
+ The primary use case of the TPDM is to collect data from different data
+ sources and send it to a TPDA for packetization, timestamping, and funneling.

+description: |
+ Some qcom based bootloaders identify the dtb blob based on a set of
+ device properties like SoC and platform and revisions of those components.
+ To support this scheme, we encode this information into the board compatible
+ string.
+
+ Each board must specify a top-level board compatible string with the following
+ format:
+
+ compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
+
+ The 'SoC' and 'board' elements are required. All other elements are optional.
+
+ The 'SoC' element must be one of the following strings:
+
+ apq8016
+ apq8026
+ apq8074
+ apq8084
+ apq8096
+ ipq4018
+ ipq5018

+ sm6375
+ sm7225
+ sm8150
+ sm8250
+ sm8350
+ sm8450
+ sm8550
+
+ The 'board' element must be one of the following strings:
+
+ adp
+ ap-al02-c2
+ ap-al02-c6
+ ap-al02-c7
+ ap-al02-c8
+ ap-al02-c9

+ hk10-c2
+ idp
+ liquid
+ rdp432-c2
+ mtp
+ qrd
+ rb2
+ ride
+ sbc
+ x100
+
+ The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
+ where the minor number may be omitted when it's zero, i.e. v1.0 is the same
+ as v1. If all versions of the 'board_version' elements match, then a
+ wildcard '*' should be used, e.g. 'v*'.
+
+ The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
+
+ Examples:
+
+ "qcom,msm8916-v1-cdp-pm8916-v2.1"
+
+ A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
+ 2.1.
+
+ "qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
+
+ A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in
+ foundry 2.
+
+ There are many devices in the list below that run the standard ChromeOS
+ bootloader setup and use the open source depthcharge bootloader to boot the
+ OS. These devices do not use the scheme described above. For details, see:

+* ARM Secure world bindings
+
+ARM CPUs with TrustZone support have two distinct address spaces,
+"Normal" and "Secure". Most devicetree consumers (including the Linux
+kernel) are not TrustZone aware and run entirely in either the Normal
+world or the Secure world. However some devicetree consumers are
+TrustZone aware and need to be able to determine whether devices are
+visible only in the Secure address space, only in the Normal address
+space, or visible in both. (One example of that situation would be a
+virtual machine which boots Secure firmware and wants to tell the
+firmware about the layout of the machine via devicetree.)
+
+The general principle of the naming scheme for Secure world bindings
+is that any property that needs a different value in the Secure world
+can be supported by prefixing the property name with "secure-". So for
+instance "secure-foo" would override "foo". For property names with
+a vendor prefix, the Secure variant of "vendor,foo" would be
+"vendor,secure-foo". If there is no "secure-" property then the Secure
+world value is the same as specified for the Normal world by the
+non-prefixed property. However, only the properties listed below may
+validly have "secure-" versions; this list will be enlarged on a
+case-by-case basis.
+
+Defining the bindings in this way means that a device tree which has
+been annotated to indicate the presence of Secure-only devices can
+still be processed unmodified by existing Non-secure software (and in
+particular by the kernel).
+
+Note that it is still valid for bindings intended for purely Secure
+world consumers (like kernels that run entirely in Secure) to simply
+describe the view of Secure world using the standard bindings. These
+secure- bindings only need to be used where both the Secure and Normal
+world views need to be described in a single device tree.
+
+Valid Secure world properties
+-----------------------------
+
+- secure-status : specifies whether the device is present and usable
+ in the secure world. The combination of this with "status" allows
+ the various possible combinations of device visibility to be
+ specified. If "secure-status" is not specified it defaults to the
+ same value as "status"; if "status" is not specified either then
+ both default to "okay". This means the following combinations are
+ possible:
+
+ /* Neither specified: default to visible in both S and NS */
+ secure-status = "okay"; /* visible in both */
+ status = "okay"; /* visible in both */
+ status = "okay"; secure-status = "okay"; /* visible in both */
+ secure-status = "disabled"; /* NS-only */
+ status = "okay"; secure-status = "disabled"; /* NS-only */
+ status = "disabled"; secure-status = "okay"; /* S-only */
+ status = "disabled"; /* disabled in both */
+ status = "disabled"; secure-status = "disabled"; /* disabled in both */
+
+The secure-chosen node
+----------------------
+
+Similar to the /chosen node which serves as a place for passing data
+between firmware and the operating system, the /secure-chosen node may
+be used to pass data to the Secure OS. Only the properties defined
+below may appear in the /secure-chosen node.
+
+- stdout-path : specifies the device to be used by the Secure OS for
+ its console output. The syntax is the same as for /chosen/stdout-path.
+ If the /secure-chosen node exists but the stdout-path property is not
+ present, the Secure OS should not perform any console output. If
+ /secure-chosen does not exist, the Secure OS should use the value of
+ /chosen/stdout-path instead (that is, use the same device as the
+ Normal world OS).

+Synaptics SoC Device Tree Bindings
+
+According to https://www.synaptics.com/company/news/conexant-marvell
+Synaptics has acquired the Multimedia Solutions Business of Marvell, so
+berlin SoCs are now Synaptics' SoCs now.
+
+---------------------------------------------------------------
+
+Work in progress statement:
+
+Device tree files and bindings applying to Marvell Berlin SoCs and boards are
+considered "unstable". Any Marvell Berlin device tree binding may change at any
+time. Be sure to use a device tree binary and a kernel image generated from the
+same source tree.
+
+Please refer to Documentation/devicetree/bindings/ABI.rst for a definition of a
+stable binding/ABI.
+
+---------------------------------------------------------------
+
+Boards with a SoC of the Marvell Berlin family, e.g. Armada 1500
+shall have the following properties:
+
+* Required root node properties:
+compatible: must contain "marvell,berlin"
+
+In addition, the above compatible shall be extended with the specific
+SoC and board used. Currently known SoC compatibles are:
+ "marvell,berlin2" for Marvell Armada 1500 (BG2, 88DE3100),
+ "marvell,berlin2cd" for Marvell Armada 1500-mini (BG2CD, 88DE3005)
+ "marvell,berlin2ct" for Marvell Armada ? (BG2CT, 88DE????)
+ "marvell,berlin2q" for Marvell Armada 1500-pro (BG2Q, 88DE3114)
+ "marvell,berlin3" for Marvell Armada ? (BG3, 88DE????)
+
+* Example:
+
+/ {
+ model = "Sony NSZ-GS7";
+ compatible = "sony,nsz-gs7", "marvell,berlin2", "marvell,berlin";
+
+ ...
+}
+
+* Marvell Berlin CPU control bindings
+
+CPU control register allows various operations on CPUs, like resetting them
+independently.
+
+Required properties:
+- compatible: should be "marvell,berlin-cpu-ctrl"
+- reg: address and length of the register set
+
+Example:
+
+cpu-ctrl@f7dd0000 {
+ compatible = "marvell,berlin-cpu-ctrl";
+ reg = <0xf7dd0000 0x10000>;
+};
+
+* Marvell Berlin2 chip control binding
+
+Marvell Berlin SoCs have a chip control register set providing several
+individual registers dealing with pinmux, padmux, clock, reset, and secondary
+CPU boot address. Unfortunately, the individual registers are spread among the
+chip control registers, so there should be a single DT node only providing the
+different functions which are described below.
+
+Required properties:
+- compatible:
+ * the first and second values must be:
+ "simple-mfd", "syscon"
+- reg: address and length of following register sets for
+ BG2/BG2CD: chip control register set
+ BG2Q: chip control register set and cpu pll registers
+
+* Marvell Berlin2 system control binding
+
+Marvell Berlin SoCs have a system control register set providing several
+individual registers dealing with pinmux, padmux, and reset.
+
+Required properties:
+- compatible:
+ * the first and second values must be:
+ "simple-mfd", "syscon"
+- reg: address and length of the system control register set
+
+Example:
+
+chip: chip-control@ea0000 {
+ compatible = "simple-mfd", "syscon";
+ reg = <0xea0000 0x400>;
+
+ /* sub-device nodes */
+};
+
+sysctrl: system-controller@d000 {
+ compatible = "simple-mfd", "syscon";
+ reg = <0xd000 0x100>;
+
+ /* sub-device nodes */
+};

+ These are pad configuration nodes. On Tegra SoCs a pad is a set of

+ configuration varies depending on the pad in question. 3.3 V and
+ 1.8 V signaling voltages are supported on pins where software
+ controllable signaling voltage switching is available.
+

+
+description: |+
+ The Control Backbone (CBB) is comprised of the physical path from an
+ initiator to a target's register configuration space. CBB 1.0 has
+ multiple hierarchical sub-NOCs (Network-on-Chip) and connects various
+ initiators and targets using different bridges like AXIP2P, AXI2APB.
+
+ This driver handles errors due to illegal register accesses reported
+ by the NOCs inside the CBB. NOCs reporting errors are cluster NOCs
+ "AON-NOC, SCE-NOC, RCE-NOC, BPMP-NOC, CV-NOC" and "CBB Central NOC"
+ which is the main NOC.
+
+ By default, the access issuing initiator is informed about the error
+ using SError or Data Abort exception unless the ERD (Error Response
+ Disable) is enabled/set for that initiator. If the ERD is enabled, then
+ SError or Data Abort is masked and the error is reported with interrupt.
+
+ - For CCPLEX (CPU Complex) initiator, the driver sets ERD bit. So, the
+ errors due to illegal accesses from CCPLEX are reported by interrupts.
+ If ERD is not set, then error is reported by SError.
+ - For other initiators, the ERD is disabled. So, the access issuing
+ initiator is informed about the illegal access by Data Abort exception.
+ In addition, an interrupt is also generated to CCPLEX. These initiators
+ include all engines using Cortex-R5 (which is ARMv7 CPU cluster) and
+ engines like TSEC (Security co-processor), NVDEC (NVIDIA Video Decoder
+ engine) etc which can initiate transactions.
+
+ The driver prints relevant debug information like Error Code, Error
+ Description, Master, Address, AXI ID, Cache, Protection, Security Group
+ etc on receiving error notification.

+ This is a Pad configuration node. On Tegra SOCs a pad is a set of
+ pins which are configured as a group. The pin grouping is a fixed
+ attribute of the hardware. The PMC can be used to set pad power state
+ and signaling voltage. A pad can be either in active or power down mode.
+ The support for power state and signaling voltage configuration varies
+ depending on the pad in question. 3.3V and 1.8V signaling voltages
+ are supported on pins where software controllable signaling voltage
+ switching is available.
+
+ The pad configuration state nodes are placed under the pmc node and they
+ are referred to by the pinctrl client properties. For more information
+ see Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
+ The pad name should be used as the value of the pins property in pin
+ configuration nodes.

+
+description: |+
+ The Control Backbone (CBB) is comprised of the physical path from an
+ initiator to a target's register configuration space. CBB 2.0 consists
+ of multiple sub-blocks connected to each other to create a topology.
+ The Tegra234 SoC has different fabrics based on CBB 2.0 architecture
+ which include cluster fabrics BPMP, AON, PSC, SCE, RCE, DCE, FSI and
+ "CBB central fabric".
+
+ In CBB 2.0, each initiator which can issue transactions connects to a
+ Root Master Node (MN) before it connects to any other element of the
+ fabric. Each Root MN contains a Error Monitor (EM) which detects and
+ logs error. Interrupts from various EM blocks are collated by Error
+ Notifier (EN) which is per fabric and presents a single interrupt from
+ fabric to the SoC interrupt controller.
+
+ The driver handles errors from CBB due to illegal register accesses
+ and prints debug information about failed transaction on receiving
+ the interrupt from EN. Debug information includes Error Code, Error
+ Description, MasterID, Fabric, SlaveID, Address, Cache, Protection,
+ Security Group etc on receiving error notification.
+
+ If the Error Response Disable (ERD) is set/enabled for an initiator,
+ then SError or Data abort exception error response is masked and an
+ interrupt is used for reporting errors due to illegal accesses from
+ that initiator. The value returned on read failures is '0xFFFFFFFF'
+ for compatibility with PCIE.

+ARM Versatile Express Serial Configuration Controller
+-----------------------------------------------------
+
+Test chips for ARM Versatile Express platform implement SCC (Serial
+Configuration Controller) interface, used to set initial conditions
+for the test chip.
+
+In some cases its registers are also mapped in normal address space
+and can be used to obtain runtime information about the chip internals
+(like silicon temperature sensors) and as interface to other subsystems
+like platform configuration control and power management.
+
+Required properties:
+
+- compatible value: "arm,vexpress-scc,<model>", "arm,vexpress-scc";
+ where <model> is the full tile model name (as used
+ in the tile's Technical Reference Manual),
+ eg. for Coretile Express A15x2 A7x3 (V2P-CA15_A7):
+ compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc";
+
+Optional properties:
+
+- reg: when the SCC is memory mapped, physical address and size of the
+ registers window
+- interrupts: when the SCC can generate a system-level interrupt
+
+Example:
+
+ scc@7fff0000 {
+ compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc";
+ reg = <0 0x7fff0000 0 0x1000>;
+ interrupts = <0 95 4>;

+* Xen hypervisor device tree bindings
+
+Xen ARM virtual platforms shall have a top-level "hypervisor" node with
+the following properties:
+
+- compatible:
+ compatible = "xen,xen-<version>", "xen,xen";
+ where <version> is the version of the Xen ABI of the platform.
+
+- reg: specifies the base physical address and size of the regions in memory
+ where the special resources should be mapped to, using an HYPERVISOR_memory_op
+ hypercall.
+ Region 0 is reserved for mapping grant table, it must be always present.
+ The memory region is large enough to map the whole grant table (it is larger
+ or equal to gnttab_max_grant_frames()).
+ Regions 1...N are extended regions (unused address space) for mapping foreign
+ GFNs and grants, they might be absent if there is nothing to expose.
+
+- interrupts: the interrupt used by Xen to inject event notifications.
+ A GIC node is also required.
+
+To support UEFI on Xen ARM virtual platforms, Xen populates the FDT "uefi" node
+under /hypervisor with following parameters:
+
+________________________________________________________________________________
+Name | Size | Description
+================================================================================
+xen,uefi-system-table | 64-bit | Guest physical address of the UEFI System
+ | | Table.
+--------------------------------------------------------------------------------
+xen,uefi-mmap-start | 64-bit | Guest physical address of the UEFI memory
+ | | map.
+--------------------------------------------------------------------------------
+xen,uefi-mmap-size | 32-bit | Size in bytes of the UEFI memory map
+ | | pointed to in previous entry.
+--------------------------------------------------------------------------------
+xen,uefi-mmap-desc-size | 32-bit | Size in bytes of each entry in the UEFI
+ | | memory map.
+--------------------------------------------------------------------------------
+xen,uefi-mmap-desc-ver | 32-bit | Version of the mmap descriptor format.
+--------------------------------------------------------------------------------
+
+Example (assuming #address-cells = <2> and #size-cells = <2>):
+
+hypervisor {
+ compatible = "xen,xen-4.3", "xen,xen";
+ reg = <0 0xb0000000 0 0x20000>;
+ interrupts = <1 15 0xf08>;
+ uefi {
+ xen,uefi-system-table = <0xXXXXXXXX>;
+ xen,uefi-mmap-start = <0xXXXXXXXX>;
+ xen,uefi-mmap-size = <0xXXXXXXXX>;
+ xen,uefi-mmap-desc-size = <0xXXXXXXXX>;
+ xen,uefi-mmap-desc-ver = <0xXXXXXXXX>;
+ };
+};
+
+The format and meaning of the "xen,uefi-*" parameters are similar to those in
+Documentation/arch/arm/uefi.rst, which are provided by the regular UEFI stub. However

+* APM X-Gene 6.0 Gb/s SATA host controller nodes
+
+SATA host controller nodes are defined to describe on-chip Serial ATA
+controllers. Each SATA controller (pair of ports) have its own node.
+
+Required properties:
+- compatible : Shall contain:
+ * "apm,xgene-ahci"
+- reg : First memory resource shall be the AHCI memory
+ resource.
+ Second memory resource shall be the host controller
+ core memory resource.
+ Third memory resource shall be the host controller
+ diagnostic memory resource.
+ 4th memory resource shall be the host controller
+ AXI memory resource.
+ 5th optional memory resource shall be the host
+ controller MUX memory resource if required.
+- interrupts : Interrupt-specifier for SATA host controller IRQ.
+- clocks : Reference to the clock entry.
+- phys : A list of phandles + phy-specifiers, one for each
+ entry in phy-names.
+- phy-names : Should contain:
+ * "sata-phy" for the SATA 6.0Gbps PHY
+
+Optional properties:
+- dma-coherent : Present if dma operations are coherent
+- status : Shall be "ok" if enabled or "disabled" if disabled.
+ Default is "ok".

+description: |
+ This controller is the first Faraday IDE interface block, used in the
+ StorLink SL3512 and SL3516, later known as the Cortina Systems Gemini
+ platform. The controller can do PIO modes 0 through 4, Multi-word DMA
+ (MWDM) modes 0 through 2 and Ultra DMA modes 0 through 6.
+
+ On the Gemini platform, this PATA block is accompanied by a PATA to
+ SATA bridge in order to support SATA. This is why a phandle to that
+ controller is compulsory on that platform.
+
+ The timing properties are unique per-SoC, not per-board.

+Freescale Reference Board Bindings
+
+This document describes device tree bindings for various devices that
+exist on some Freescale reference boards.
+
+* Board Control and Status (BCSR)
+
+Required properties:
+
+ - compatible : Should be "fsl,<board>-bcsr"
+ - reg : Offset and length of the register set for the device
+
+Example:
+
+ bcsr@f8000000 {
+ compatible = "fsl,mpc8360mds-bcsr";
+ reg = <f8000000 8000>;
+ };
+
+* Freescale on-board FPGA
+
+This is the memory-mapped registers for on board FPGA.
+
+Required properties:
+- compatible: should be a board-specific string followed by a string
+ indicating the type of FPGA. Example:
+ "fsl,<board>-fpga", "fsl,fpga-pixis", or
+ "fsl,<board>-fpga", "fsl,fpga-qixis"
+- reg: should contain the address and the length of the FPGA register set.
+
+Optional properties:
+- interrupts: should specify event (wakeup) IRQ.
+
+Example (P1022DS):
+
+ board-control@3,0 {
+ compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
+ reg = <3 0 0x30>;
+ interrupt-parent = <&mpic>;
+ interrupts = <8 8 0 0>;
+ };
+
+Example (LS2080A-RDB):
+
+ cpld@3,0 {
+ compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis";
+ reg = <0x3 0 0x10000>;
+ };
+
+* Freescale on-board FPGA connected on I2C bus
+
+Some Freescale boards like BSC9132QDS have on board FPGA connected on
+the i2c bus.
+
+Required properties:
+- compatible: Should be a board-specific string followed by a string
+ indicating the type of FPGA. Example:
+ "fsl,<board>-fpga", "fsl,fpga-qixis-i2c"
+- reg: Should contain the address of the FPGA
+
+Example:
+ fpga: fpga@66 {
+ compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
+ reg = <0x66>;
+ };
+
+* Freescale on-board CPLD
+
+Some Freescale boards like T1040RDB have an on board CPLD connected.
+
+Required properties:
+- compatible: Should be a board-specific string like "fsl,<board>-cpld"
+ Example:
+ "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
+- reg: should describe CPLD registers
+
+Example:
+ cpld@3,0 {
+ compatible = "fsl,t1040rdb-cpld";
+ reg = <3 0 0x300>;
+ };

+description: |
+ AXI3-bus is the main communication bus of Baikal-T1 SoC connecting all
+ high-speed peripheral IP-cores with RAM controller and with MIPS P5600
+ cores. Traffic arbitration is done by means of DW AXI Interconnect (so
+ called AXI Main Interconnect) routing IO requests from one block to
+ another: from CPU to SoC peripherals and between some SoC peripherals
+ (mostly between peripheral devices and RAM, but also between DMA and
+ some peripherals). In case of any protocol error, device not responding
+ an IRQ is raised and a faulty situation is reported to the AXI EHB
+ (Errors Handler Block) embedded on top of the DW AXI Interconnect and
+ accessible by means of the Baikal-T1 System Controller.

+Driver for ARM AXI Bus with Broadcom Plugins (bcma)
+
+Required properties:
+
+- compatible : brcm,bus-axi
+
+- reg : iomem address range of chipcommon core
+
+The cores on the AXI bus are automatically detected by bcma with the
+memory ranges they are using and they get registered afterwards.
+Automatic detection of the IRQ number is not working on
+BCM47xx/BCM53xx ARM SoCs. To assign IRQ numbers to the cores, provide
+them manually through device tree. Use an interrupt-map to specify the
+IRQ used by the devices on the bus. The first address is just an index,
+because we do not have any special register.
+
+The top-level axi bus may contain children representing attached cores
+(devices). This is needed since some hardware details can't be auto
+detected (e.g. IRQ numbers). Also some of the cores may be responsible
+for extra things, e.g. ChipCommon providing access to the GPIO chip.
+
+Example:
+
+ axi@18000000 {
+ compatible = "brcm,bus-axi";
+ reg = <0x18000000 0x1000>;

+maintainers:

+
+description: |
+ i.MX8qxp pixel link MSI bus is used to control settings of PHYs, I/Os
+ sitting together with the PHYs. It is not the same as the MSI bus coming
+ from i.MX8 System Controller Unit (SCU) which is used to control power,
+ clock and reset through the i.MX8 Distributed Slave System Controller (DSC).
+
+ i.MX8qxp pixel link MSI bus is a simple memory-mapped bus. Two input clocks,
+ that is, MSI clock and AHB clock, need to be enabled so that peripherals
+ connected to the bus can be accessed. Also, the bus is part of a power
+ domain. The power domain needs to be enabled before the peripherals can
+ be accessed.
+
+ Peripherals in i.MX8qm/qxp imaging, LVDS, MIPI DSI and HDMI TX subsystems,
+ like I2C controller, PWM controller, MIPI DSI controller and Control and
+ Status Registers (CSR) module, are accessed through the bus.
+
+ The i.MX System Controller Firmware (SCFW) owns and uses the i.MX8qm/qxp
+ pixel link MSI bus controller and does not allow SCFW user to control it.
+ So, the controller's registers cannot be accessed by SCFW user. Hence,
+ the interrupts generated by the controller don't make any sense from SCFW
+ user's point of view.

+Device tree bindings for i.MX Wireless External Interface Module (WEIM)
+
+The term "wireless" does not imply that the WEIM is literally an interface
+without wires. It simply means that this module was originally designed for
+wireless and mobile applications that use low-power technology.
+
+The actual devices are instantiated from the child nodes of a WEIM node.
+
+Required properties:
+
+ - compatible: Should contain one of the following:
+ "fsl,imx1-weim"
+ "fsl,imx27-weim"
+ "fsl,imx51-weim"
+ "fsl,imx50-weim"
+ "fsl,imx6q-weim"
+ - reg: A resource specifier for the register space
+ (see the example below)
+ - clocks: the clock, see the example below.
+ - #address-cells: Must be set to 2 to allow memory address translation
+ - #size-cells: Must be set to 1 to allow CS address passing
+ - ranges: Must be set up to reflect the memory layout with four
+ integer values for each chip-select line in use:
+
+ <cs-number> 0 <physical address of mapping> <size>
+
+Optional properties:
+
+ - fsl,weim-cs-gpr: For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
+ devices, it should be the phandle to the system General
+ Purpose Register controller that contains WEIM CS GPR
+ register, e.g. IOMUXC_GPR1 on i.MX6Q. IOMUXC_GPR1[11:0]
+ should be set up as one of the following 4 possible
+ values depending on the CS space configuration.
+
+ IOMUXC_GPR1[11:0] CS0 CS1 CS2 CS3
+ ---------------------------------------------
+ 05 128M 0M 0M 0M
+ 033 64M 64M 0M 0M
+ 0113 64M 32M 32M 0M
+ 01111 32M 32M 32M 32M
+
+ In case that the property is absent, the reset value or
+ what bootloader sets up in IOMUXC_GPR1[11:0] will be
+ used.
+
+ - fsl,burst-clk-enable For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
+ devices, the presence of this property indicates that
+ the weim bus should operate in Burst Clock Mode.
+
+ - fsl,continuous-burst-clk Make Burst Clock to output continuous clock.
+ Without this option Burst Clock will output clock
+ only when necessary. This takes effect only if
+ "fsl,burst-clk-enable" is set.
+
+Timing property for child nodes. It is mandatory, not optional.
+
+ - fsl,weim-cs-timing: The timing array, contains timing values for the
+ child node. We get the CS indexes from the address
+ ranges in the child node's "reg" property.
+ The number of registers depends on the selected chip:
+ For i.MX1, i.MX21 ("fsl,imx1-weim") there are two
+ registers: CSxU, CSxL.
+ For i.MX25, i.MX27, i.MX31 and i.MX35 ("fsl,imx27-weim")
+ there are three registers: CSCRxU, CSCRxL, CSCRxA.
+ For i.MX50, i.MX53 ("fsl,imx50-weim"),
+ i.MX51 ("fsl,imx51-weim") and i.MX6Q ("fsl,imx6q-weim")
+ there are six registers: CSxGCR1, CSxGCR2, CSxRCR1,
+ CSxRCR2, CSxWCR1, CSxWCR2.
+
+Example for an imx6q-sabreauto board, the NOR flash connected to the WEIM:
+
+ weim: weim@21b8000 {
+ compatible = "fsl,imx6q-weim";
+ reg = <0x021b8000 0x4000>;
+ clocks = <&clks 196>;
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <0 0 0x08000000 0x08000000>;
+ fsl,weim-cs-gpr = <&gpr>;
+
+ nor@0,0 {
+ compatible = "cfi-flash";
+ reg = <0 0 0x02000000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ bank-width = <2>;
+ fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
+ 0x0000c000 0x1404a38e 0x00000000>;
+ };
+ };
+
+Example for an imx6q-based board, a multi-chipselect device connected to WEIM:
+
+In this case, both chip select 0 and 1 will be configured with the same timing
+array values.
+
+ weim: weim@21b8000 {
+ compatible = "fsl,imx6q-weim";
+ reg = <0x021b8000 0x4000>;

+ compatible strings)
+
+Example:
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;

+ };
+
+ /* more children ...*/
+ };
+ };
+
+** MBus address decoding window specification
+
+The MBus children address space is comprised of two cells: the first one for
+the window ID and the second one for the offset within the window.
+In order to allow to describe valid and non-valid window entries, the
+following encoding is used:
+
+ 0xSIAA0000 0x00oooooo
+
+Where:
+
+ S = 0x0 for a MBus valid window
+ S = 0xf for a non-valid window (see below)
+
+If S = 0x0, then:
+
+ I = 4-bit window target ID
+ AA = windpw attribute
+
+If S = 0xf, then:
+
+ I = don't care
+ AA = 1 for internal register
+
+Following the above encoding, for each ranges entry for a MBus valid window
+(S = 0x0), an address decoding window is allocated. On the other side,
+entries for translation that do not correspond to valid windows (S = 0xf)
+are skipped.
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = <0xf0010000 0 0 0xd0000000 0x100000
+ 0x01e00000 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <0x01e00000 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ ranges = <0 0xf0010000 0 0x100000>;
+
+ mbusc: mbus-controller@20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>, <0x20250 0x8>;
+ };
+
+ /* more children ...*/
+ };
+ };
+
+In the shown example, the translation entry in the 'ranges' property is what
+makes the MBus driver create a static decoding window for the corresponding
+given child device. Note that the binding does not require child nodes to be
+present. Of course, child nodes are needed to probe the devices.
+
+Since each window is identified by its target ID and attribute ID there's
+a special macro that can be use to simplify the translation entries:
+
+#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))
+
+Using this macro, the above example would be:
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = < MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000
+ MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>;
+
+ mbusc: mbus-controller@20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>, <0x20250 0x8>;
+ };
+
+ /* other children */
+ ...
+ };
+ };
+
+
+** About the window base address
+
+Remember the MBus controller allows a great deal of flexibility for choosing
+the decoding window base address. When planning the device tree layout it's
+possible to choose any address as the base address, provided of course there's
+a region large enough available, and with the required alignment.
+
+Yet in other words: there's nothing preventing us from setting a base address
+of 0xf0000000, or 0xd0000000 for the NOR device shown above, if such region is
+unused.
+
+** Window allocation policy
+
+The mbus-node ranges property defines a set of mbus windows that are expected
+to be set by the operating system and that are guaranteed to be free of overlaps
+with one another or with the system memory ranges.
+
+Each entry in the property refers to exactly one window. If the operating system
+chooses to use a different set of mbus windows, it must ensure that any address
+translations performed from downstream devices are adapted accordingly.
+
+The operating system may insert additional mbus windows that do not conflict
+with the ones listed in the ranges, e.g. for mapping PCIe devices.
+As a special case, the internal register window must be set up by the boot
+loader at the address listed in the ranges property, since access to that region
+is needed to set up the other windows.
+
+** Example
+
+See the example below, where a more complete device tree is shown:
+
+ soc {
+ compatible = "marvell,armadaxp-mbus", "simple-bus";
+ controller = <&mbusc>;

+Device tree bindings for NVIDIA Tegra Generic Memory Interface bus
+
+The Generic Memory Interface bus enables memory transfers between internal and
+external memory. Can be used to attach various high speed devices such as
+synchronous/asynchronous NOR, FPGA, UARTS and more.
+
+The actual devices are instantiated from the child nodes of a GMI node.
+
+Required properties:
+ - compatible : Should contain one of the following:
+ For Tegra20 must contain "nvidia,tegra20-gmi".
+ For Tegra30 must contain "nvidia,tegra30-gmi".
+ - reg: Should contain GMI controller registers location and length.
+ - clocks: Must contain an entry for each entry in clock-names.
+ - clock-names: Must include the following entries: "gmi"
+ - resets : Must contain an entry for each entry in reset-names.
+ - reset-names : Must include the following entries: "gmi"
+ - #address-cells: The number of cells used to represent physical base
+ addresses in the GMI address space. Should be 2.
+ - #size-cells: The number of cells used to represent the size of an address
+ range in the GMI address space. Should be 1.
+ - ranges: Must be set up to reflect the memory layout with three integer values
+ for each chip-select line in use (only one entry is supported, see below
+ comments):
+ <cs-number> <offset> <physical address of mapping> <size>
+
+Note that the GMI controller does not have any internal chip-select address
+decoding, because of that chip-selects either need to be managed via software
+or by employing external chip-select decoding logic.
+
+If external chip-select logic is used to support multiple devices it is assumed
+that the devices use the same timing and so are probably the same type. It also
+assumes that they can fit in the 256MB address range. In this case only one
+child device is supported which represents the active chip-select line, see
+examples for more insight.
+
+The chip-select number is decoded from the child nodes second address cell of
+'ranges' property, if 'ranges' property is not present or empty chip-select will
+then be decoded from the first cell of the 'reg' property.
+
+Optional child cs node properties:
+
+ - nvidia,snor-data-width-32bit: Use 32bit data-bus, default is 16bit.
+ - nvidia,snor-mux-mode: Enable address/data MUX mode.
+ - nvidia,snor-rdy-active-before-data: Assert RDY signal one cycle before data.
+ If omitted it will be asserted with data.
+ - nvidia,snor-rdy-active-high: RDY signal is active high
+ - nvidia,snor-adv-active-high: ADV signal is active high
+ - nvidia,snor-oe-active-high: WE/OE signal is active high
+ - nvidia,snor-cs-active-high: CS signal is active high
+
+ Note that there is some special handling for the timing values.
+ From Tegra TRM:
+ Programming 0 means 1 clock cycle: actual cycle = programmed cycle + 1
+
+ - nvidia,snor-muxed-width: Number of cycles MUX address/data asserted on the
+ bus. Valid values are 0-15, default is 1
+ - nvidia,snor-hold-width: Number of cycles CE stays asserted after the
+ de-assertion of WR_N (in case of SLAVE/MASTER Request) or OE_N
+ (in case of MASTER Request). Valid values are 0-15, default is 1
+ - nvidia,snor-adv-width: Number of cycles during which ADV stays asserted.
+ Valid values are 0-15, default is 1.
+ - nvidia,snor-ce-width: Number of cycles before CE is asserted.
+ Valid values are 0-15, default is 4
+ - nvidia,snor-we-width: Number of cycles during which WE stays asserted.
+ Valid values are 0-15, default is 1
+ - nvidia,snor-oe-width: Number of cycles during which OE stays asserted.
+ Valid values are 0-255, default is 1
+ - nvidia,snor-wait-width: Number of cycles before READY is asserted.
+ Valid values are 0-255, default is 3
+
+Example with two SJA1000 CAN controllers connected to the GMI bus. We wrap the
+controllers with a simple-bus node since they are all connected to the same
+chip-select (CS4), in this example external address decoding is provided:
+
+gmi@70009000 {

+Qualcomm External Bus Interface 2 (EBI2)
+
+The EBI2 contains two peripheral blocks: XMEM and LCDC. The XMEM handles any
+external memory (such as NAND or other memory-mapped peripherals) whereas
+LCDC handles LCD displays.
+
+As it says it connects devices to an external bus interface, meaning address
+lines (up to 9 address lines so can only address 1KiB external memory space),
+data lines (16 bits), OE (output enable), ADV (address valid, used on some
+NOR flash memories), WE (write enable). This on top of 6 different chip selects
+(CS0 thru CS5) so that in theory 6 different devices can be connected.
+
+Apparently this bus is clocked at 64MHz. It has dedicated pins on the package
+and the bus can only come out on these pins, however if some of the pins are
+unused they can be left unconnected or remuxed to be used as GPIO or in some
+cases other orthogonal functions as well.
+
+Also CS1 and CS2 has -A and -B signals. Why they have that is unclear to me.
+
+The chip selects have the following memory range assignments. This region of
+memory is referred to as "Chip Peripheral SS FPB0" and is 168MB big.
+
+Chip Select Physical address base
+CS0 GPIO134 0x1a800000-0x1b000000 (8MB)
+CS1 GPIO39 (A) / GPIO123 (B) 0x1b000000-0x1b800000 (8MB)
+CS2 GPIO40 (A) / GPIO124 (B) 0x1b800000-0x1c000000 (8MB)
+CS3 GPIO133 0x1d000000-0x25000000 (128 MB)
+CS4 GPIO132 0x1c800000-0x1d000000 (8MB)
+CS5 GPIO131 0x1c000000-0x1c800000 (8MB)
+
+The APQ8060 Qualcomm Application Processor User Guide, 80-N7150-14 Rev. A,
+August 6, 2012 contains some incomplete documentation of the EBI2.
+
+FIXME: the manual mentions "write precharge cycles" and "precharge cycles".
+We have not been able to figure out which bit fields these correspond to
+in the hardware, or what valid values exist. The current hypothesis is that
+this is something just used on the FAST chip selects and that the SLOW
+chip selects are understood fully. There is also a "byte device enable"
+flag somewhere for 8bit memories.
+
+FIXME: The chipselects have SLOW and FAST configuration registers. It's a bit
+unclear what this means, if they are mutually exclusive or can be used
+together, or if some chip selects are hardwired to be FAST and others are SLOW
+by design.
+
+The XMEM registers are totally undocumented but could be partially decoded
+because the Cypress AN49576 Antioch Westbridge apparently has suspiciously
+similar register layout, see: http://www.cypress.com/file/105771/download
+
+Required properties:
+- compatible: should be one of:
+ "qcom,msm8660-ebi2"
+ "qcom,apq8060-ebi2"
+- #address-cells: should be <2>: the first cell is the chipselect,
+ the second cell is the offset inside the memory range
+- #size-cells: should be <1>
+- ranges: should be set to:
+ ranges = <0 0x0 0x1a800000 0x00800000>,
+ <1 0x0 0x1b000000 0x00800000>,
+ <2 0x0 0x1b800000 0x00800000>,
+ <3 0x0 0x1d000000 0x08000000>,
+ <4 0x0 0x1c800000 0x00800000>,
+ <5 0x0 0x1c000000 0x00800000>;
+- reg: two ranges of registers: EBI2 config and XMEM config areas
+- reg-names: should be "ebi2", "xmem"
+- clocks: two clocks, EBI_2X and EBI
+- clock-names: should be "ebi2x", "ebi2"
+
+Optional subnodes:
+- Nodes inside the EBI2 will be considered device nodes.
+
+The following optional properties are properties that can be tagged onto
+any device subnode. We are assuming that there can be only ONE device per
+chipselect subnode, else the properties will become ambiguous.
+
+Optional properties arrays for SLOW chip selects:
+- qcom,xmem-recovery-cycles: recovery cycles is the time the memory continues to
+ drive the data bus after OE is de-asserted, in order to avoid contention on
+ the data bus. They are inserted when reading one CS and switching to another
+ CS or read followed by write on the same CS. Valid values 0 thru 15. Minimum
+ value is actually 1, so a value of 0 will still yield 1 recovery cycle.
+- qcom,xmem-write-hold-cycles: write hold cycles, these are extra cycles
+ inserted after every write minimum 1. The data out is driven from the time
+ WE is asserted until CS is asserted. With a hold of 1 (value = 0), the CS
+ stays active for 1 extra cycle etc. Valid values 0 thru 15.
+- qcom,xmem-write-delta-cycles: initial latency for write cycles inserted for
+ the first write to a page or burst memory. Valid values 0 thru 255.
+- qcom,xmem-read-delta-cycles: initial latency for read cycles inserted for the
+ first read to a page or burst memory. Valid values 0 thru 255.
+- qcom,xmem-write-wait-cycles: number of wait cycles for every write access, 0=1
+ cycle. Valid values 0 thru 15.
+- qcom,xmem-read-wait-cycles: number of wait cycles for every read access, 0=1
+ cycle. Valid values 0 thru 15.
+
+Optional properties arrays for FAST chip selects:
+- qcom,xmem-address-hold-enable: this is a boolean property stating that we
+ shall hold the address for an extra cycle to meet hold time requirements
+ with ADV assertion.
+- qcom,xmem-adv-to-oe-recovery-cycles: the number of cycles elapsed before an OE
+ assertion, with respect to the cycle where ADV (address valid) is asserted.
+ 2 means 2 cycles between ADV and OE. Valid values 0, 1, 2 or 3.
+- qcom,xmem-read-hold-cycles: the length in cycles of the first segment of a
+ read transfer. For a single read transfer this will be the time from CS
+ assertion to OE assertion. Valid values 0 thru 15.
+
+
+Example:

+ compatible = "qcom,apq8060-ebi2";

+
+description: |
+ The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
+ Bridge", or "External Bus Interface") can be found in several Renesas ARM
+ SoCs. It provides an external bus for connecting multiple external
+ devices to the SoC, driving several chip select lines, for e.g. NOR
+ FLASH, Ethernet and USB.
+
+ While the BSC is a fairly simple memory-mapped bus, it may be part of a
+ PM domain, and may have a gateable functional clock. Before a device
+ connected to the BSC can be accessed, the PM domain containing the BSC
+ must be powered on, and the functional clock driving the BSC must be
+ enabled.
+
+ The bindings for the BSC extend the bindings for "simple-pm-bus".

+title: UniPhier System Bus
+
+description: |
+ The UniPhier System Bus is an external bus that connects on-board devices to
+ the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
+ some control signals. It supports up to 8 banks (chip selects).
+
+ Before any access to the bus, the bus controller must be configured; the bus
+ controller registers provide the control for the translation from the offset
+ within each bank to the CPU-viewed address. The needed setup includes the
+ base address, the size of each bank. Optionally, some timing parameters can
+ be optimized for faster bus access.

+ Provide address translation from the System Bus to the parent bus.
+
+ Note:
+ The address region(s) that can be assigned for the System Bus is
+ implementation defined. Some SoCs can use 0x00000000-0x0fffffff and
+ 0x40000000-0x4fffffff, while other SoCs only 0x40000000-0x4fffffff.
+ There might be additional limitations depending on SoCs and the boot mode.
+ The address translation is arbitrary as long as the banks are assigned in
+ the supported address space with the required alignment and they do not
+ overlap one another.
+
+ For example, it is possible to map:
+ bank 0 to 0x42000000-0x43ffffff, bank 5 to 0x46000000-0x46ffffff
+ It is also possible to map:
+ bank 0 to 0x48000000-0x49ffffff, bank 5 to 0x44000000-0x44ffffff
+ There is no reason to stick to a particular translation mapping, but the
+ "ranges" property should provide a "reasonable" default that is known to
+ work. The software should initialize the bus controller according to it.

+title: Texas Instruments interconnect target module

+
+description:
+ Texas Instruments SoCs can have a generic interconnect target module
+ for devices connected to various interconnects such as L3 interconnect
+ using Arteris NoC, and L4 interconnect using Sonics s3220. This module
+ is mostly used for interaction between module and Power, Reset and Clock
+ Manager PRCM. It participates in the OCP Disconnect Protocol, but other
+ than that it is mostly independent of the interconnect.
+
+ Each interconnect target module can have one or more devices connected to
+ it. There is a set of control registers for managing the interconnect target
+ module clocks, idle modes and interconnect level resets.
+
+ The interconnect target module control registers are sprinkled into the
+ unused register address space of the first child device IP block managed by
+ the interconnect target module. Typically the register names are REVISION,
+ SYSCONFIG and SYSSTATUS.

+title: AMD CDX bus controller
+
+description: |
+ CDX bus controller for AMD devices is implemented to dynamically
+ detect CDX bus and devices using the firmware.
+ The CDX bus manages multiple FPGA based hardware devices, which
+ can support network, crypto or any other specialized type of
+ devices. These FPGA based devices can be added/modified dynamically
+ on run-time.
+
+ All devices on the CDX bus will have a unique streamid (for IOMMU)
+ and a unique device ID (for MSI) corresponding to a requestor ID
+ (one to one associated with the device). The streamid and deviceid
+ are used to configure SMMU and GIC-ITS respectively.
+
+ iommu-map property is used to define the set of stream ids
+ corresponding to each device and the associated IOMMU.
+
+ The MSI writes are accompanied by sideband data (Device ID).
+ The msi-map property is used to associate the devices with the
+ device ID as well as the associated ITS controller.
+
+ rproc property (xlnx,rproc) is used to identify the remote processor
+ with which APU (Application Processor Unit) interacts to find out
+ the bus and device configuration.

+description: |+
+ ARM cores often have a separate L2C210/L2C220/L2C310 (also known as PL210/
+ PL220/PL310 and variants) based level 2 cache controller. All these various
+ implementations of the L2 cache controller have compatible programming
+ models (Note 1). Some of the properties that are just prefixed "cache-*" are
+ taken from section 3.7.3 of the Devicetree Specification which can be found
+ at:
+ https://www.devicetree.org/specifications/
+
+ Note 1: The description in this document doesn't apply to integrated L2
+ cache controllers as found in e.g. Cortex-A15/A7/A57/A53. These
+ integrated L2 controllers are assumed to be all preconfigured by
+ early secure boot code. Thus no need to deal with their configuration
+ in the kernel at all.

+description: |
+ LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
+ that can be shared by multiple clients. Clients here are different cores in the
+ SoC, the idea is to minimize the local caches at the clients and migrate to
+ common pool of memory. Cache memory is divided into partitions called slices
+ which are assigned to clients. Clients can query the slice details, activate
+ and deactivate them.

+* Actions Semi Owl Clock Management Unit (CMU)
+
+The Actions Semi Owl Clock Management Unit generates and supplies clock
+to various controllers within the SoC. The clock binding described here is
+applicable to S900, S700 and S500 SoC's.
+
+Required Properties:
+
+- compatible: should be one of the following,
+ "actions,s900-cmu"
+ "actions,s700-cmu"
+ "actions,s500-cmu"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- clocks: Reference to the parent clocks ("hosc", "losc")
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Each clock is assigned an identifier, and client nodes can use this identifier
+to specify the clock which they consume.
+
+All available clocks are defined as preprocessor macros in corresponding
+dt-bindings/clock/actions,s900-cmu.h or actions,s700-cmu.h or
+actions,s500-cmu.h header and can be used in device tree sources.
+
+External clocks:
+
+The hosc clock used as input for the plls is generated outside the SoC. It is
+expected that it is defined using standard clock bindings as "hosc".
+
+Actions Semi S900 CMU also requires one more clock:
+ - "losc" - internal low frequency oscillator
+
+Example: Clock Management Unit node:
+
+ cmu: clock-controller@e0160000 {
+ compatible = "actions,s900-cmu";
+ reg = <0x0 0xe0160000 0x0 0x1000>;
+ clocks = <&hosc>, <&losc>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes clock generated by the clock
+management unit:
+
+ uart: serial@e012a000 {
+ compatible = "actions,s900-uart", "actions,owl-uart";
+ reg = <0x0 0xe012a000 0x0 0x2000>;
+ interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cmu CLK_UART5>;
+ };

+Alphascale Clock Controller
+
+The ACC (Alphascale Clock Controller) is responsible for choosing proper
+clock source, setting dividers and clock gates.
+
+Required properties for the ACC node:
+ - compatible: must be "alphascale,asm9260-clock-controller"
+ - reg: must contain the ACC register base and size
+ - #clock-cells : shall be set to 1.
+
+Simple one-cell clock specifier format is used, where the only cell is used
+as an index of the clock inside the provider.
+It is encouraged to use dt-binding for clock index definitions. SoC specific
+dt-binding should be included to the device tree descriptor. For example
+Alphascale ASM9260:
+#include <dt-bindings/clock/alphascale,asm9260.h>
+
+This binding contains two types of clock providers:
+ _AHB_ - AHB gate;
+ _SYS_ - adjustable clock source. Not all peripheral have _SYS_ clock provider.
+All clock specific details can be found in the SoC documentation.

+Device Tree Clock bindings for Altera's SoCFPGA platform
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+ "altr,socfpga-pll-clock" - for a PLL clock
+ "altr,socfpga-perip-clock" - The peripheral clock divided from the
+ PLL clock.
+ "altr,socfpga-gate-clk" - Clocks that directly feed peripherals and
+ can get gated.
+
+- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
+- clocks : shall be the input parent clock phandle for the clock. This is
+ either an oscillator or a pll output.
+- #clock-cells : from common clock binding, shall be set to 0.
+
+Optional properties:
+- fixed-divider : If clocks have a fixed divider value, use this property.
+- clk-gate : For "socfpga-gate-clk", clk-gate contains the gating register
+ and the bit index.
+- div-reg : For "socfpga-gate-clk" and "socfpga-periph-clock", div-reg contains
+ the divider register, bit shift, and width.
+- clk-phase : For the sdmmc_clk, contains the value of the clock phase that controls
+ the SDMMC CIU clock. The first value is the clk_sample(smpsel), and the second
+ value is the cclk_in_drv(drvsel). The clk-phase is used to enable the correct
+ hold/delay times that is needed for the SD/MMC CIU clock. The values of both
+ can be 0-315 degrees, in 45 degree increments.

+* Amlogic AXG Audio Clock Controllers
+
+The Amlogic AXG audio clock controller generates and supplies clock to the
+other elements of the audio subsystem, such as fifos, i2s, spdif and pdm
+devices.
+
+Required Properties:
+
+- compatible : should be "amlogic,axg-audio-clkc" for the A113X and A113D,
+ "amlogic,g12a-audio-clkc" for G12A,
+ "amlogic,sm1-audio-clkc" for S905X3.
+- reg : physical base address of the clock controller and length of
+ memory mapped region.
+- clocks : a list of phandle + clock-specifier pairs for the clocks listed
+ in clock-names.
+- clock-names : must contain the following:
+ * "pclk" - Main peripheral bus clock
+ may contain the following:
+ * "mst_in[0-7]" - 8 input plls to generate clock signals
+ * "slv_sclk[0-9]" - 10 slave bit clocks provided by external
+ components.
+ * "slv_lrclk[0-9]" - 10 slave sample clocks provided by external
+ components.
+- resets : phandle of the internal reset line
+- #clock-cells : should be 1.
+- #reset-cells : should be 1 on the g12a (and following) soc family
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/axg-audio-clkc.h header and can be
+used in device tree sources.
+
+Example:
+
+clkc_audio: clock-controller@0 {
+ compatible = "amlogic,axg-audio-clkc";
+ reg = <0x0 0x0 0x0 0xb4>;

+
+description: |
+ The ICS525 and ICS307 oscillators are produced by Integrated
+ Devices Technology (IDT). ARM integrated these oscillators deeply into their
+ reference designs by adding special control registers that manage such
+ oscillators to their system controllers.
+
+ The various ARM system controllers contain logic to serialize and initialize
+ an ICST clock request after a write to the 32 bit register at an offset
+ into the system controller. Furthermore, to even be able to alter one of
+ these frequencies, the system controller must first be unlocked by
+ writing a special token to another offset in the system controller.
+
+ Some ARM hardware contain special versions of the serial interface that only
+ connects the low 8 bits of the VDW (missing one bit), hard-wires RDW to
+ different values and sometimes also hard-wires the output divider. They
+ therefore have special compatible strings as per this table (the OD value is
+ the value on the pins, not the resulting output divider).
+
+ In the core modules and logic tiles, the ICST is a configurable clock fed
+ from a 24 MHz clock on the motherboard (usually the main crystal) used for
+ generating e.g. video clocks. It is located on the core module and there is
+ only one of these. This clock node must be a subnode of the core module.

+
+maintainers:
+ - Serge Semin <fancer.lancer@gmail.com>
+
+description: |
+ Clocks Control Unit is the core of Baikal-T1 SoC System Controller
+ responsible for the chip subsystems clocking and resetting. The CCU is
+ connected with an external fixed rate oscillator, which signal is transformed
+ into clocks of various frequencies and then propagated to either individual
+ IP-blocks or to groups of blocks (clock domains). The transformation is done
+ by means of an embedded into CCU PLLs and gateable/non-gateable dividers. The
+ later ones are described in this binding. Each clock domain can be also
+ individually reset by using the domain clocks divider configuration
+ registers. Baikal-T1 CCU is logically divided into the next components:
+ 1) External oscillator (normally XTAL's 25 MHz crystal oscillator, but
+ in general can provide any frequency supported by the CCU PLLs).
+ 2) PLLs clocks generators (PLLs).
+ 3) AXI-bus clock dividers (AXI) - described in this binding file.
+ 4) System devices reference clock dividers (SYS) - described in this binding
+ file.
+ which are connected with each other as shown on the next figure:
+
+ +---------------+
+ | Baikal-T1 CCU |
+ | +----+------|- MIPS P5600 cores
+ | +-|PLLs|------|- DDR controller
+ | | +----+ |
+ +----+ | | | | |
+ |XTAL|--|-+ | | +---+-|
+ +----+ | | | +-|AXI|-|- AXI-bus
+ | | | +---+-|
+ | | | |
+ | | +----+---+-|- APB-bus
+ | +-------|SYS|-|- Low-speed Devices
+ | +---+-|- High-speed Devices
+ +---------------+
+
+ Each sub-block is represented as a separate DT node and has an individual
+ driver to be bound with.
+
+ In order to create signals of wide range frequencies the external oscillator
+ output is primarily connected to a set of CCU PLLs. Some of PLLs CLKOUT are
+ then passed over CCU dividers to create signals required for the target clock
+ domain (like AXI-bus or System Device consumers). The dividers have the
+ following structure:
+
+ +--------------+
+ CLKIN --|->+----+ 1|\ |
+ SETCLK--|--|/DIV|->| | |
+ CLKDIV--|--| | | |-|->CLKLOUT
+ LOCK----|--+----+ | | |
+ | |/ |
+ | | |
+ EN------|-----------+ |
+ RST-----|--------------|->RSTOUT
+ +--------------+
+
+ where CLKIN is the reference clock coming either from CCU PLLs or from an
+ external clock oscillator, SETCLK - a command to update the output clock in
+ accordance with a set divider, CLKDIV - clocks divider, LOCK - a signal of
+ the output clock stabilization, EN - enable/disable the divider block,
+ RST/RSTOUT - reset clocks domain signal. Depending on the consumer IP-core
+ peculiarities the dividers may lack of some functionality depicted on the
+ figure above (like EN, CLKDIV/LOCK/SETCLK). In this case the corresponding
+ clock provider just doesn't expose either switching functions, or the rate
+ configuration, or both of them.
+
+ The clock dividers, which output clock is then consumed by the SoC individual
+ devices, are united into a single clocks provider called System Devices CCU.
+ Similarly the dividers with output clocks utilized as AXI-bus reference clocks
+ are called AXI-bus CCU. Both of them use the common clock bindings with no

+
+description: |
+ Clocks Control Unit is the core of Baikal-T1 SoC System Controller
+ responsible for the chip subsystems clocking and resetting. The CCU is
+ connected with an external fixed rate oscillator, which signal is transformed
+ into clocks of various frequencies and then propagated to either individual
+ IP-blocks or to groups of blocks (clock domains). The transformation is done
+ by means of PLLs and gateable/non-gateable dividers embedded into the CCU.
+ It's logically divided into the next components:
+ 1) External oscillator (normally XTAL's 25 MHz crystal oscillator, but
+ in general can provide any frequency supported by the CCU PLLs).
+ 2) PLLs clocks generators (PLLs) - described in this binding file.
+ 3) AXI-bus clock dividers (AXI).
+ 4) System devices reference clock dividers (SYS).
+ which are connected with each other as shown on the next figure:
+
+ +---------------+
+ | Baikal-T1 CCU |
+ | +----+------|- MIPS P5600 cores
+ | +-|PLLs|------|- DDR controller
+ | | +----+ |
+ +----+ | | | | |
+ |XTAL|--|-+ | | +---+-|
+ +----+ | | | +-|AXI|-|- AXI-bus
+ | | | +---+-|
+ | | | |
+ | | +----+---+-|- APB-bus
+ | +-------|SYS|-|- Low-speed Devices
+ | +---+-|- High-speed Devices
+ +---------------+
+
+ Each CCU sub-block is represented as a separate dts-node and has an
+ individual driver to be bound with.
+
+ In order to create signals of wide range frequencies the external oscillator
+ output is primarily connected to a set of CCU PLLs. There are five PLLs
+ to create a clock for the MIPS P5600 cores, the embedded DDR controller,
+ SATA, Ethernet and PCIe domains. The last three domains though named by the
+ biggest system interfaces in fact include nearly all of the rest SoC
+ peripherals. Each of the PLLs is based on True Circuits TSMC CLN28HPM core
+ with an interface wrapper (so called safe PLL' clocks switcher) to simplify
+ the PLL configuration procedure. The PLLs work as depicted on the next
+ diagram:
+
+ +--------------------------+
+ | |
+ +-->+---+ +---+ +---+ | +---+ 0|\
+ CLKF--->|/NF|--->|PFD|...|VCO|-+->|/OD|--->| |
+ +---+ +->+---+ +---+ /->+---+ | |--->CLKOUT
+ CLKOD---------C----------------+ 1| |
+ +--------C--------------------------->|/
+ | | ^
+ Rclk-+->+---+ | |
+ CLKR--->|/NR|-+ |
+ +---+ |
+ BYPASS--------------------------------------+
+ BWADJ--->
+
+ where Rclk is the reference clock coming from XTAL, NR - reference clock
+ divider, NF - PLL clock multiplier, OD - VCO output clock divider, CLKOUT -
+ output clock, BWADJ is the PLL bandwidth adjustment parameter. At this moment
+ the binding supports the PLL dividers configuration in accordance with a
+ requested rate, while bypassing and bandwidth adjustment settings can be
+ added in future if it gets to be necessary.
+
+ The PLLs CLKOUT is then either directly connected with the corresponding
+ clocks consumer (like P5600 cores or DDR controller) or passed over a CCU
+ divider to create a signal required for the clock domain.
+
+ The CCU PLL dts-node uses the common clock bindings with no custom
+ parameters. The list of exported clocks can be found in
+ 'include/dt-bindings/clock/bt1-ccu.h'. Since CCU PLL is a part of the
+ Baikal-T1 SoC System Controller its DT node is supposed to be a child of
+ later one.

+Broadcom BCM2835 CPRMAN clocks
+
+This binding uses the common clock binding:
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CPRMAN clock controller generates clocks in the audio power domain
+of the BCM2835. There is a level of PLLs deriving from an external
+oscillator, a level of PLL dividers that produce channels off of the
+few PLLs, and a level of mostly-generic clock generators sourcing from
+the PLL channels. Most other hardware components source from the

+Required properties:
+- compatible: should be one of the following,

+ "brcm,bcm2835-cprman"
+- #clock-cells: Should be <1>. The permitted clock-specifier values can be

+- reg: Specifies base physical address and size of the registers
+- clocks: phandles to the parent clocks used as input to the module, in

+
+ - External oscillator
+ - DSI0 byte clock
+ - DSI0 DDR2 clock
+ - DSI0 DDR clock
+ - DSI1 byte clock
+ - DSI1 DDR2 clock
+ - DSI1 DDR clock
+
+ Only external oscillator is required. The DSI clocks may
+ not be present, in which case their children will be
+ unusable.

+Broadcom BCM53573 ILP clock
+===========================
+
+This binding uses the common clock binding:
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+This binding is used for ILP clock (sometimes referred as "slow clock")
+on Broadcom BCM53573 devices using Cortex-A7 CPU.
+
+ILP's rate has to be calculated on runtime and it depends on ALP clock
+which has to be referenced.
+
+This clock is part of PMU (Power Management Unit), a Broadcom's device
+handing power-related aspects. Its node must be sub-node of the PMU
+device.
+
+Required properties:
+- compatible: "brcm,bcm53573-ilp"
+- clocks: has to reference an ALP clock
+- #clock-cells: should be <0>
+- clock-output-names: from common clock bindings, should contain clock
+ name

+Broadcom Kona Family Clocks
+
+This binding is associated with Broadcom SoCs having "Kona" style
+clock control units (CCUs). A CCU is a clock provider that manages
+a set of clock signals. Each CCU is represented by a node in the
+device tree.
+
+This binding uses the common clock binding:
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible
+ Shall have a value of the form "brcm,<model>-<which>-ccu",
+ where <model> is a Broadcom SoC model number and <which> is
+ the name of a defined CCU. For example:
+ "brcm,bcm11351-root-ccu"
+ The compatible strings used for each supported SoC family
+ are defined below.
+- reg
+ Shall define the base and range of the address space
+ containing clock control registers
+- #clock-cells
+ Shall have value <1>. The permitted clock-specifier values
+ are defined below.
+- clock-output-names
+ Shall be an ordered list of strings defining the names of
+ the clocks provided by the CCU.
+
+Device tree example:
+
+ slave_ccu: slave_ccu {
+ compatible = "brcm,bcm11351-slave-ccu";
+ reg = <0x3e011000 0x0f00>;

+
+The following table defines the set of CCUs and clock specifiers for

+* Palmas 32KHz clocks *
+
+Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO.
+
+This binding uses the common clock binding ./clock-bindings.txt.
+
+Required properties:
+- compatible : "ti,palmas-clk32kg" for clk32kg clock
+ "ti,palmas-clk32kgaudio" for clk32kgaudio clock
+- #clock-cells : shall be set to 0.
+
+Optional property:
+- ti,external-sleep-control: The external enable input pins controlled the
+ enable/disable of clocks. The external enable input pins ENABLE1,
+ ENABLE2 and NSLEEP. The valid values for the external pins are:
+ PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin
+ PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin
+ PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin
+ Option 0 or missing this property means the clock is enabled/disabled
+ via register access and these pins do not have any control.
+ The macros of external control pins for DTS is defined at
+ dt-bindings/mfd/palmas.h
+
+Example:
+ #include <dt-bindings/mfd/palmas.h>
+ ...
+ palmas: tps65913@58 {

+2 VMeta clock
+3 LCD clock
+
+Required properties:
+- compatible : shall be "marvell,dove-divider-clock"

+description: |
+ It is possible to use the BCLK pin of a SAI module as a generic clock
+ output. Some SoC are very constrained in their pin multiplexer
+ configuration. Eg. pins can only be changed groups. For example, on the
+ LS1028A SoC you can only enable SAIs in pairs. If you use only one SAI,
+ the second pins are wasted. Using this binding it is possible to use the
+ clock of the second SAI as a MCLK clock for an audio codec, for example.
+
+ This is a composite of a gated clock and a divider clock.

+The reset specifier consists of two cells. The first cell represents the

+bit index in the register.
+
+Example: CRG nodes

+title: IDT VersaClock 5 and 6 programmable I2C clock generators
+
+description: |
+ The IDT VersaClock 5 and VersaClock 6 are programmable I2C
+ clock generators providing from 3 to 12 output clocks.
+
+ When referencing the provided clock in the DT using phandle and clock
+ specifier, the following mapping applies:
+
+ - 5P49V5923:
+ 0 -- OUT0_SEL_I2CB
+ 1 -- OUT1
+ 2 -- OUT2
+
+ - 5P49V5933:
+ 0 -- OUT0_SEL_I2CB
+ 1 -- OUT1
+ 2 -- OUT4
+
+ - other parts:
+ 0 -- OUT0_SEL_I2CB
+ 1 -- OUT1
+ 2 -- OUT2
+ 3 -- OUT3
+ 4 -- OUT4
+
+ The idt,shutdown and idt,output-enable-active properties control the
+ SH (en_global_shutdown) and SP bits of the Primary Source and Shutdown
+ Register, respectively. Their behavior is summarized by the following
+ table:
+
+ SH SP Output when the SD/OE pin is Low/High
+ == == =====================================
+ 0 0 Active/Inactive
+ 0 1 Inactive/Active
+ 1 0 Active/Shutdown
+ 1 1 Inactive/Shutdown
+
+ The case where SH and SP are both 1 is likely not very interesting.

+* NXP LPC1850 Clock Generation Unit (CGU)
+
+The CGU generates multiple independent clocks for the core and the
+peripheral blocks of the LPC18xx. Each independent clock is called
+a base clock and itself is one of the inputs to the two Clock
+Control Units (CCUs) which control the branch clocks to the
+individual peripherals.
+
+The CGU selects the inputs to the clock generators from multiple
+clock sources, controls the clock generation, and routes the outputs
+of the clock generators through the clock source bus to the output
+stages. Each output stage provides an independent clock source and
+corresponds to one of the base clocks for the LPC18xx.

+Devicetree bindings for Maxim MAX9485 Programmable Audio Clock Generator
+
+This device exposes 4 clocks in total:
+
+- MAX9485_MCLKOUT: A gated, buffered output of the input clock of 27 MHz
+- MAX9485_CLKOUT: A PLL that can be configured to 16 different discrete
+ frequencies
+- MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT
+
+MAX9485_CLKOUT[1,2] are children of MAX9485_CLKOUT which upchain all rate set
+requests.
+
+Required properties:
+- compatible: "maxim,max9485"
+- clocks: Input clock, must provide 27.000 MHz
+- clock-names: Must be set to "xclk"
+- #clock-cells: From common clock binding; shall be set to 1
+
+Optional properties:
+- reset-gpios: GPIO descriptor connected to the #RESET input pin
+- vdd-supply: A regulator node for Vdd
+- clock-output-names: Name of output clocks, as defined in common clock
+ bindings
+
+If not explicitly set, the output names are "mclkout", "clkout", "clkout1"
+and "clkout2".
+
+Clocks are defined as preprocessor macros in the dt-binding header.
+
+Example:

+- #clock-cells: shall be 1.
+
+Optional properties:
+- microchip,pic32mzda-sosc: shall be added only if platform has
+ secondary oscillator connected.
+
+Example:
+ rootclk: clock-controller@1f801200 {

+
+The clock consumer shall specify the desired clock-output of the clock
+controller (as defined in [2]) by specifying output-id in its "clock"
+phandle cell.
+[2] include/dt-bindings/clock/microchip,pic32-clock.h

+* Nuvoton NPCM7XX Clock Controller
+
+Nuvoton Poleg BMC NPCM7XX contains an integrated clock controller, which
+generates and supplies clocks to all modules within the BMC.
+
+External clocks:
+
+There are six fixed clocks that are generated outside the BMC. All clocks are of
+a known fixed value that cannot be changed. clk_refclk, clk_mcbypck and
+clk_sysbypck are inputs to the clock controller.
+clk_rg1refck, clk_rg2refck and clk_xin are external clocks suppling the
+network. They are set on the device tree, but not used by the clock module. The
+network devices use them directly.
+Example can be found below.
+
+All available clocks are defined as preprocessor macros in:
+dt-bindings/clock/nuvoton,npcm7xx-clock.h
+and can be reused as DT sources.
+
+Required Properties of clock controller:
+
+ - compatible: "nuvoton,npcm750-clk" : for clock controller of Nuvoton
+ Poleg BMC NPCM750
+
+ - reg: physical base address of the clock controller and length of
+ memory mapped region.
+
+ - #clock-cells: should be 1.
+
+Example: Clock controller node:
+
+ clk: clock-controller@f0801000 {
+ compatible = "nuvoton,npcm750-clk";
+ #clock-cells = <1>;
+ reg = <0xf0801000 0x1000>;
+ clock-names = "refclk", "sysbypck", "mcbypck";
+ clocks = <&clk_refclk>, <&clk_sysbypck>, <&clk_mcbypck>;
+ };
+
+Example: Required external clocks for network:
+
+ /* external reference clock */
+ clk_refclk: clk-refclk {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <25000000>;
+ clock-output-names = "refclk";
+ };
+
+ /* external reference clock for cpu. float in normal operation */
+ clk_sysbypck: clk-sysbypck {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <800000000>;
+ clock-output-names = "sysbypck";
+ };
+
+ /* external reference clock for MC. float in normal operation */
+ clk_mcbypck: clk-mcbypck {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <800000000>;

+ };
+
+ /* external clock signal rg1refck, supplied by the phy */

+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <125000000>;
+ clock-output-names = "clk_rg1refck";

+NVIDIA Tegra124 DFLL FCPU clocksource
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The DFLL IP block on Tegra is a root clocksource designed for clocking
+the fast CPU cluster. It consists of a free-running voltage controlled
+oscillator connected to the CPU voltage rail (VDD_CPU), and a closed loop
+control module that will automatically adjust the VDD_CPU voltage by
+communicating with an off-chip PMIC either via an I2C bus or via PWM signals.
+
+Required properties:
+- compatible : should be one of:
+ - "nvidia,tegra124-dfll": for Tegra124
+ - "nvidia,tegra210-dfll": for Tegra210
+- reg : Defines the following set of registers, in the order listed:
+ - registers for the DFLL control logic.
+ - registers for the I2C output logic.
+ - registers for the integrated I2C master controller.
+ - look-up table RAM for voltage register values.
+- interrupts: Should contain the DFLL block interrupt.
+- clocks: Must contain an entry for each entry in clock-names.
+ See clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - soc: Clock source for the DFLL control logic.
+ - ref: The closed loop reference clock
+ - i2c: Clock source for the integrated I2C master.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - dvco: Reset control for the DFLL DVCO.
+- #clock-cells: Must be 0.
+- clock-output-names: Name of the clock output.
+- vdd-cpu-supply: Regulator for the CPU voltage rail that the DFLL
+ hardware will start controlling. The regulator will be queried for
+ the I2C register, control values and supported voltages.
+
+Required properties for the control loop parameters:
+- nvidia,sample-rate: Sample rate of the DFLL control loop.
+- nvidia,droop-ctrl: See the register CL_DVFS_DROOP_CTRL in the TRM.
+- nvidia,force-mode: See the field DFLL_PARAMS_FORCE_MODE in the TRM.
+- nvidia,cf: Numeric value, see the field DFLL_PARAMS_CF_PARAM in the TRM.
+- nvidia,ci: Numeric value, see the field DFLL_PARAMS_CI_PARAM in the TRM.
+- nvidia,cg: Numeric value, see the field DFLL_PARAMS_CG_PARAM in the TRM.
+
+Optional properties for the control loop parameters:
+- nvidia,cg-scale: Boolean value, see the field DFLL_PARAMS_CG_SCALE in the TRM.
+
+Optional properties for mode selection:
+- nvidia,pwm-to-pmic: Use PWM to control regulator rather then I2C.
+
+Required properties for I2C mode:
+- nvidia,i2c-fs-rate: I2C transfer rate, if using full speed mode.
+
+Required properties for PWM mode:
+- nvidia,pwm-period-nanoseconds: period of PWM square wave in nanoseconds.
+- nvidia,pwm-tristate-microvolts: Regulator voltage in micro volts when PWM
+ control is disabled and the PWM output is tristated. Note that this voltage is
+ configured in hardware, typically via a resistor divider.
+- nvidia,pwm-min-microvolts: Regulator voltage in micro volts when PWM control
+ is enabled and PWM output is low. Hence, this is the minimum output voltage
+ that the regulator supports when PWM control is enabled.
+- nvidia,pwm-voltage-step-microvolts: Voltage increase in micro volts
+ corresponding to a 1/33th increase in duty cycle. Eg the voltage for 2/33th
+ duty cycle would be: nvidia,pwm-min-microvolts +
+ nvidia,pwm-voltage-step-microvolts * 2.
+- pinctrl-0: I/O pad configuration when PWM control is enabled.
+- pinctrl-1: I/O pad configuration when PWM control is disabled.
+- pinctrl-names: must include the following entries:
+ - dvfs_pwm_enable: I/O pad configuration when PWM control is enabled.
+ - dvfs_pwm_disable: I/O pad configuration when PWM control is disabled.

+Imagination Technologies Pistachio SoC clock controllers
+========================================================
+
+Pistachio has four clock controllers (core clock, peripheral clock, peripheral
+general control, and top general control) which are instantiated individually
+from the device-tree.
+
+External clocks:
+----------------
+
+There are three external inputs to the clock controllers which should be
+defined with the following clock-output-names:
+- "xtal": External 52Mhz oscillator (required)
+- "audio_clk_in": Alternate audio reference clock (optional)
+- "enet_clk_in": Alternate ethernet PHY clock (optional)
+
+Core clock controller:
+----------------------
+
+The core clock controller generates clocks for the CPU, RPU (WiFi + BT
+co-processor), audio, and several peripherals.
+
+Required properties:
+- compatible: Must be "img,pistachio-clk".
+- reg: Must contain the base address and length of the core clock controller.
+- #clock-cells: Must be 1. The single cell is the clock identifier.
+ See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
+- clocks: Must contain an entry for each clock in clock-names.
+- clock-names: Must include "xtal" (see "External clocks") and
+ "audio_clk_in_gate", "enet_clk_in_gate" which are generated by the
+ top-level general control.
+
+Example:
+ clk_core: clock-controller@18144000 {
+ compatible = "img,pistachio-clk";
+ reg = <0x18144000 0x800>;
+ clocks = <&xtal>, <&cr_top EXT_CLK_AUDIO_IN>,
+ <&cr_top EXT_CLK_ENET_IN>;
+ clock-names = "xtal", "audio_clk_in_gate", "enet_clk_in_gate";
+
+ #clock-cells = <1>;
+ };
+
+Peripheral clock controller:
+----------------------------
+
+The peripheral clock controller generates clocks for the DDR, ROM, and other
+peripherals. The peripheral system clock ("periph_sys") generated by the core
+clock controller is the input clock to the peripheral clock controller.
+
+Required properties:
+- compatible: Must be "img,pistachio-periph-clk".
+- reg: Must contain the base address and length of the peripheral clock
+ controller.
+- #clock-cells: Must be 1. The single cell is the clock identifier.
+ See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
+- clocks: Must contain an entry for each clock in clock-names.
+- clock-names: Must include "periph_sys", the peripheral system clock generated
+ by the core clock controller.
+
+Example:
+ clk_periph: clock-controller@18144800 {
+ compatible = "img,pistachio-clk-periph";
+ reg = <0x18144800 0x800>;
+ clocks = <&clk_core CLK_PERIPH_SYS>;
+ clock-names = "periph_sys";
+
+ #clock-cells = <1>;
+ };
+
+Peripheral general control:
+---------------------------
+
+The peripheral general control block generates system interface clocks and
+resets for various peripherals. It also contains miscellaneous peripheral
+control registers. The system clock ("sys") generated by the peripheral clock
+controller is the input clock to the system clock controller.
+
+Required properties:
+- compatible: Must include "img,pistachio-periph-cr" and "syscon".
+- reg: Must contain the base address and length of the peripheral general
+ control registers.
+- #clock-cells: Must be 1. The single cell is the clock identifier.
+ See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
+- clocks: Must contain an entry for each clock in clock-names.
+- clock-names: Must include "sys", the system clock generated by the peripheral
+ clock controller.
+
+Example:
+ cr_periph: syscon@18144800 {
+ compatible = "img,pistachio-cr-periph", "syscon";
+ reg = <0x18148000 0x1000>;
+ clocks = <&clock_periph PERIPH_CLK_PERIPH_SYS>;
+ clock-names = "sys";
+
+ #clock-cells = <1>;
+ };
+
+Top-level general control:
+--------------------------
+
+The top-level general control block contains miscellaneous control registers and
+gates for the external clocks "audio_clk_in" and "enet_clk_in".
+
+Required properties:
+- compatible: Must include "img,pistachio-cr-top" and "syscon".
+- reg: Must contain the base address and length of the top-level
+ control registers.
+- clocks: Must contain an entry for each clock in clock-names.
+- clock-names: Two optional clocks, "audio_clk_in" and "enet_clk_in" (see
+ "External clocks").
+- #clock-cells: Must be 1. The single cell is the clock identifier.
+ See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
+
+Example:
+ cr_top: syscon@18144800 {
+ compatible = "img,pistachio-cr-top", "syscon";
+ reg = <0x18149000 0x200>;
+ clocks = <&audio_refclk>, <&ext_enet_in>;
+ clock-names = "audio_clk_in", "enet_clk_in";
+
+ #clock-cells = <1>;
+ };

+ The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
+ There is one ACC register region per CPU within the KPSS remapped region as
+ well as an alias register region that remaps accesses to the ACC associated
+ with the CPU accessing the region. ACC v1 is currently used as a
+ clock-controller for enabling the cpu and handling the aux clocks.

+description: |
+ The clock enumerators are defined in <dt-bindings/clock/qcom,rpmcc.h> and
+ come in pairs:: FOO_CLK followed by FOO_A_CLK. The latter clock is
+ an "active" clock, which means that the consumer only care that the clock is
+ available when the apps CPU subsystem is active, i.e. not suspended or in
+ deep idle. If it is important that the clock keeps running during system
+ suspend, you need to specify the non-active clock, the one not containing
+ *_A_* in the enumerator name.

+* Clock Block on Freescale QorIQ Platforms
+
+Freescale QorIQ chips take primary clocking input from the external
+SYSCLK signal. The SYSCLK input (frequency) is multiplied using
+multiple phase locked loops (PLL) to create a variety of frequencies
+which can then be passed to a variety of internal logic, including
+cores and peripheral IP blocks.
+Please refer to the Reference Manual for details.
+
+All references to "1.0" and "2.0" refer to the QorIQ chassis version to
+which the chip complies.
+
+Chassis Version Example Chips
+--------------- -------------
+1.0 p4080, p5020, p5040
+2.0 t4240, b4860
+
+1. Clock Block Binding
+
+Required properties:
+- compatible: Should contain a chip-specific clock block compatible
+ string and (if applicable) may contain a chassis-version clock
+ compatible string.
+
+ Chip-specific strings are of the form "fsl,<chip>-clockgen", such as:
+ * "fsl,p2041-clockgen"
+ * "fsl,p3041-clockgen"
+ * "fsl,p4080-clockgen"
+ * "fsl,p5020-clockgen"
+ * "fsl,p5040-clockgen"
+ * "fsl,t1023-clockgen"
+ * "fsl,t1024-clockgen"
+ * "fsl,t1040-clockgen"
+ * "fsl,t1042-clockgen"
+ * "fsl,t2080-clockgen"
+ * "fsl,t2081-clockgen"
+ * "fsl,t4240-clockgen"
+ * "fsl,b4420-clockgen"
+ * "fsl,b4860-clockgen"
+ * "fsl,ls1012a-clockgen"
+ * "fsl,ls1021a-clockgen"
+ * "fsl,ls1028a-clockgen"
+ * "fsl,ls1043a-clockgen"
+ * "fsl,ls1046a-clockgen"
+ * "fsl,ls1088a-clockgen"
+ * "fsl,ls2080a-clockgen"
+ * "fsl,lx2160a-clockgen"
+ Chassis-version clock strings include:
+ * "fsl,qoriq-clockgen-1.0": for chassis 1.0 clocks
+ * "fsl,qoriq-clockgen-2.0": for chassis 2.0 clocks
+- reg: Describes the address of the device's resources within the
+ address space defined by its parent bus, and resource zero
+ represents the clock register set
+
+Optional properties:
+- ranges: Allows valid translation between child's address space and
+ parent's. Must be present if the device has sub-nodes.
+- #address-cells: Specifies the number of cells used to represent
+ physical base addresses. Must be present if the device has
+ sub-nodes and set to 1 if present
+- #size-cells: Specifies the number of cells used to represent
+ the size of an address. Must be present if the device has
+ sub-nodes and set to 1 if present
+- clock-frequency: Input system clock frequency (SYSCLK)
+- clocks: If clock-frequency is not specified, sysclk may be provided
+ as an input clock. Either clock-frequency or clocks must be
+ provided.
+ A second input clock, called "coreclk", may be provided if
+ core PLLs are based on a different input clock from the
+ platform PLL.
+- clock-names: Required if a coreclk is present. Valid names are
+ "sysclk" and "coreclk".
+
+2. Clock Provider
+
+The clockgen node should act as a clock provider, though in older device
+trees the children of the clockgen node are the clock providers.
+
+When the clockgen node is a clock provider, #clock-cells = <2>.
+The first cell of the clock specifier is the clock type, and the
+second cell is the clock index for the specified type.
+
+ Type# Name Index Cell
+ 0 sysclk must be 0
+ 1 cmux index (n in CLKCnCSR)
+ 2 hwaccel index (n in CLKCGnHWACSR)
+ 3 fman 0 for fm1, 1 for fm2
+ 4 platform pll n=pll/(n+1). For example, when n=1,
+ that means output_freq=PLL_freq/2.
+ 5 coreclk must be 0
+
+3. Example
+
+ clockgen: global-utilities@e1000 {
+ compatible = "fsl,p5020-clockgen", "fsl,qoriq-clockgen-1.0";
+ clock-frequency = <133333333>;
+ reg = <0xe1000 0x1000>;
+ #clock-cells = <2>;
+ };
+
+ fman@400000 {
+ ...
+ clocks = <&clockgen 3 0>;
+ ...
+ };
+}
+4. Legacy Child Nodes
+
+NOTE: These nodes are deprecated. Kernels should continue to support
+device trees with these nodes, but new device trees should not use them.
+
+Most of the bindings are from the common clock binding[1].
+ [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : Should include one of the following:
+ * "fsl,qoriq-core-pll-1.0" for core PLL clocks (v1.0)
+ * "fsl,qoriq-core-pll-2.0" for core PLL clocks (v2.0)
+ * "fsl,qoriq-core-mux-1.0" for core mux clocks (v1.0)
+ * "fsl,qoriq-core-mux-2.0" for core mux clocks (v2.0)
+ * "fsl,qoriq-sysclk-1.0": for input system clock (v1.0).
+ It takes parent's clock-frequency as its clock.
+ * "fsl,qoriq-sysclk-2.0": for input system clock (v2.0).
+ It takes parent's clock-frequency as its clock.
+ * "fsl,qoriq-platform-pll-1.0" for the platform PLL clock (v1.0)
+ * "fsl,qoriq-platform-pll-2.0" for the platform PLL clock (v2.0)
+- #clock-cells: From common clock binding. The number of cells in a
+ clock-specifier. Should be <0> for "fsl,qoriq-sysclk-[1,2].0"
+ clocks, or <1> for "fsl,qoriq-core-pll-[1,2].0" clocks.
+ For "fsl,qoriq-core-pll-[1,2].0" clocks, the single
+ clock-specifier cell may take the following values:
+ * 0 - equal to the PLL frequency
+ * 1 - equal to the PLL frequency divided by 2
+ * 2 - equal to the PLL frequency divided by 4
+
+Recommended properties:
+- clocks: Should be the phandle of input parent clock
+- clock-names: From common clock binding, indicates the clock name
+- clock-output-names: From common clock binding, indicates the names of
+ output clocks
+- reg: Should be the offset and length of clock block base address.
+ The length should be 4.

+
+description: |
+ The 5P35023 is a VersaClock programmable clock generator and
+ is designed for low-power, consumer, and high-performance PCI
+ express applications. The 5P35023 device is a three PLL
+ architecture design, and each PLL is individually programmable
+ and allowing for up to 6 unique frequency outputs.
+
+ An internal OTP memory allows the user to store the configuration
+ in the device. After power up, the user can change the device register
+ settings through the I2C interface when I2C mode is selected.
+
+ The driver can read a full register map from the DT, and will use that
+ register map to initialize the attached part (via I2C) when the system
+ boots. Any configuration not supported by the common clock framework
+ must be done via the full register map, including optimized settings.

+ On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse Generator)

+ - The CPG block generates various core clocks,
+ - The MSSR block provides two functions:
+ 1. Module Standby, providing a Clock Domain to control the clock supply
+ to individual SoC devices,
+ 2. Reset Control, to perform a software reset of individual SoC devices.

+
+description: |
+ If you connect an external clock to the USB_EXTAL pin only, you should set
+ the clock rate to "usb_extal" node only.
+ If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
+ is not needed because this is default setting. (Of course, you can set the
+ clock rates to both "usb_extal" and "usb_xtal" nodes.
+
+ Case 1: An external clock connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |External |---|USB_EXTAL ---> all usb channels|
+ |clock | |USB_XTAL |
+ +----------+ +-------------------------------+
+
+ In this case, we need this driver with "usb_extal" clock.
+
+ Case 2: An oscillator connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |Oscillator|---|USB_EXTAL -+-> all usb channels|
+ | |---|USB_XTAL --+ |
+ +----------+ +-------------------------------+
+ In this case, we don't need this selector.

+description: |
+ On Renesas RZ/{G2L,V2L}-alike SoC's, the CPG (Clock Pulse Generator) and Module
+ Standby Mode share the same register block. On RZ/V2M, the functionality is
+ similar, but does not have Clock Monitor Registers.
+
+ They provide the following functionalities:
+ - The CPG block generates various core clocks,
+ - The Module Standby Mode block provides two functions:
+ 1. Module Standby, providing a Clock Domain to control the clock supply
+ to individual SoC devices,
+ 2. Reset Control, to perform a software reset of individual SoC devices.

+* Rockchip RK3328 Clock and Reset Unit
+
+The RK3328 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3328-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+ If missing pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3328-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "gmac_clkin" - external GMAC clock - optional
+ - "phy_50m_out" - output clock of the pll in the mac phy
+ - "hdmi_phy" - output clock of the hdmi phy pll - optional
+
+Example: Clock controller node:
+
+ cru: clock-controller@ff440000 {
+ compatible = "rockchip,rk3328-cru";
+ reg = <0x0 0xff440000 0x0 0x1000>;
+ rockchip,grf = <&grf>;
+
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller:
+
+ uart0: serial@ff120000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0xff120000 0x100>;
+ interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ clocks = <&cru SCLK_UART0>;
+ };

+description: |
+ Exynos7885 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. The root clock in that root tree
+ is an external clock: OSCCLK (26 MHz). This external clock must be defined
+ as a fixed-rate clock in dts.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'dt-bindings/clock/exynos7885.h' header.

+description: |
+ Exynos850 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. Root clocks in that clock tree are
+ two external clocks:: OSCCLK (26 MHz) and RTCCLK (32768 Hz). Those external
+ clocks must be defined as fixed-rate clocks in dts.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'dt-bindings/clock/exynos850.h' header.

+* Samsung S3C64xx Clock Controller
+
+The S3C64xx clock controller generates and supplies clock to various controllers
+within the SoC. The clock binding described here is applicable to all SoCs in
+the S3C64xx family.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "samsung,s3c6400-clock" - controller compatible with S3C6400 SoC.
+ - "samsung,s3c6410-clock" - controller compatible with S3C6410 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Some of the clocks are available only
+on a particular S3C64xx SoC and this is specified where applicable.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/samsung,s3c64xx-clock.h header and can be used in device
+tree sources.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "fin_pll" - PLL input clock (xtal/extclk) - required,
+ - "xusbxti" - USB xtal - required,
+ - "iiscdclk0" - I2S0 codec clock - optional,
+ - "iiscdclk1" - I2S1 codec clock - optional,
+ - "iiscdclk2" - I2S2 codec clock - optional,
+ - "pcmcdclk0" - PCM0 codec clock - optional,
+ - "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
+
+Example: Clock controller node:
+
+ clock: clock-controller@7e00f000 {
+ compatible = "samsung,s3c6410-clock";
+ reg = <0x7e00f000 0x1000>;
+ #clock-cells = <1>;
+ };
+
+Example: Required external clocks:
+
+ fin_pll: clock-fin-pll {
+ compatible = "fixed-clock";
+ clock-output-names = "fin_pll";
+ clock-frequency = <12000000>;
+ #clock-cells = <0>;

+ compatible = "fixed-clock";
+ clock-output-names = "xusbxti";
+ clock-frequency = <48000000>;
+ #clock-cells = <0>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller (refer to the standard clock bindings for information about
+ "clocks" and "clock-names" properties):
+
+ uart0: serial@7f005000 {

+Binding for Silicon Labs Si5340, Si5341 Si5342, Si5344 and Si5345 programmable
+i2c clock generator.
+
+Reference
+[1] Si5341 Data Sheet
+ https://www.silabs.com/documents/public/data-sheets/Si5341-40-D-DataSheet.pdf
+[2] Si5341 Reference Manual
+ https://www.silabs.com/documents/public/reference-manuals/Si5341-40-D-RM.pdf
+[3] Si5345 Reference Manual
+ https://www.silabs.com/documents/public/reference-manuals/Si5345-44-42-D-RM.pdf
+
+The Si5341 and Si5340 are programmable i2c clock generators with up to 10 output
+clocks. The chip contains a PLL that sources 5 (or 4) multisynth clocks, which
+in turn can be directed to any of the 10 (or 4) outputs through a divider.
+The internal structure of the clock generators can be found in [2].
+The Si5345 is similar to the Si5341 with the addition of fractional input
+dividers and automatic input selection, as described in [3].
+The Si5342 and Si5344 are smaller versions of the Si5345, with 2 or 4 outputs.
+
+The driver can be used in "as is" mode, reading the current settings from the
+chip at boot, in case you have a (pre-)programmed device. If the PLL is not
+configured when the driver probes, it assumes the driver must fully initialize
+it.
+
+The device type, speed grade and revision are determined runtime by probing.
+
+The driver currently does not support any fancy input configurations. They can
+still be programmed into the chip and the driver will leave them "as is".
+
+==I2C device node==
+
+Required properties:
+- compatible: shall be one of the following:
+ "silabs,si5340" - Si5340 A/B/C/D
+ "silabs,si5341" - Si5341 A/B/C/D
+ "silabs,si5342" - Si5342 A/B/C/D
+ "silabs,si5344" - Si5344 A/B/C/D
+ "silabs,si5345" - Si5345 A/B/C/D
+- reg: i2c device address, usually 0x74
+- #clock-cells: from common clock binding; shall be set to 2.
+ The first value is "0" for outputs, "1" for synthesizers.
+ The second value is the output or synthesizer index.
+- clocks: from common clock binding; list of parent clock handles,
+ corresponding to inputs. Use a fixed clock for the "xtal" input.
+ At least one must be present.
+- clock-names: One of: "xtal", "in0", "in1", "in2"
+
+Optional properties:
+- vdd-supply: Regulator node for VDD
+- vdda-supply: Regulator node for VDDA
+- vdds-supply: Regulator node for VDDS
+- silabs,pll-m-num, silabs,pll-m-den: Numerator and denominator for PLL
+ feedback divider. Must be such that the PLL output is in the valid range. For
+ example, to create 14GHz from a 48MHz xtal, use m-num=14000 and m-den=48. Only
+ the fraction matters, using 3500 and 12 will deliver the exact same result.
+ If these are not specified, and the PLL is not yet programmed when the driver
+ probes, the PLL will be set to 14GHz.
+- silabs,reprogram: When present, the driver will always assume the device must
+ be initialized, and always performs the soft-reset routine. Since this will
+ temporarily stop all output clocks, don't do this if the chip is generating
+ the CPU clock for example.
+- silabs,xaxb-ext-clk: When present, indicates that the XA/XB pins are used
+ in EXTCLK (external reference clock) rather than XTAL (crystal) mode.
+- interrupts: Interrupt for INTRb pin.
+- silabs,iovdd-33: When present, indicates that the I2C lines are using 3.3V
+ rather than 1.8V thresholds.
+- vddoX-supply (where X is an output index): Regulator node for VDDO for the
+ specified output. The driver selects the output VDD_SEL setting based on this
+ voltage.
+- #address-cells: shall be set to 1.
+- #size-cells: shall be set to 0.
+
+
+== Child nodes: Outputs ==
+
+The child nodes list the output clocks.
+
+Each of the clock outputs can be overwritten individually by using a child node.
+If a child node for a clock output is not set, the configuration remains
+unchanged.
+
+Required child node properties:
+- reg: number of clock output.
+
+Optional child node properties:
+- silabs,format: Output format, one of:
+ 1 = differential (defaults to LVDS levels)
+ 2 = low-power (defaults to HCSL levels)
+ 4 = LVCMOS
+- silabs,common-mode: Manually override output common mode, see [2] for values
+- silabs,amplitude: Manually override output amplitude, see [2] for values
+- silabs,synth-master: boolean. If present, this output is allowed to change the
+ multisynth frequency dynamically.
+- silabs,silabs,disable-high: boolean. If set, the clock output is driven HIGH
+ when disabled, otherwise it's driven LOW.

+Spreadtrum SC9860 Clock Binding
+------------------------
+
+Required properties:
+- compatible: should contain the following compatible strings:

+ - "sprd,sc9860-pll"
+ - "sprd,sc9860-ap-clk"

+ - "sprd,sc9860-disp-gate"
+ - "sprd,sc9860-apapb-gate"
+
+- #clock-cells: must be 1
+
+- clocks : Should be the input parent clock(s) phandle for the clock, this
+ property here just simply shows which clock group the clocks'
+ parents are in, since each clk node would represent many clocks
+ which are defined in the driver. The detailed dependency
+ relationship (i.e. how many parents and which are the parents)
+ are implemented in driver code.
+
+Optional properties:
+
+- reg: Contain the registers base address and length. It must be configured
+ only if no 'sprd,syscon' under the node.
+
+- sprd,syscon: phandle to the syscon which is in the same address area with
+ the clock, and so we can get regmap for the clocks from the
+ syscon device.
+
+Example:
+
+ pmu_gate: pmu-gate {

+The Nomadik SRC controller is responsible of controlling chrystals,
+PLLs and clock gates.
+
+Required properties for the SRC node:
+- compatible: must be "stericsson,nomadik-src"
+- reg: must contain the SRC register base and size
+
+Optional properties for the SRC node:
+- disable-sxtalo: if present this will disable the SXTALO
+ i.e. the driver output for the slow 32kHz chrystal, if the

+- disable-mxtal: if present this will disable the MXTALO,
+ i.e. the driver output for the main (~19.2 MHz) chrystal,
+ if the board has its own circuitry for providing this
+ oscillator
+
+
+PLL nodes: these nodes represent the two PLLs on the system,
+which should both have the main chrystal, represented as a
+fixed frequency clock, as parent.
+
+Required properties for the two PLL nodes:
+- compatible: must be "st,nomadik-pll-clock"
+- clock-cells: must be 0
+- clock-id: must be 1 or 2 for PLL1 and PLL2 respectively
+- clocks: this clock will have main chrystal as parent
+
+
+HCLK nodes: these represent the clock gates on individual
+lines from the HCLK clock tree and the gate for individual
+lines from the PCLK clock tree.
+
+Requires properties for the HCLK nodes:
+- compatible: must be "st,nomadik-hclk-clock"
+- clock-cells: must be 0
+- clock-id: must be the clock ID from 0 to 63 according to
+ this table:

+STMicroelectronics STM32 Reset and Clock Controller
+===================================================
+
+The RCC IP is both a reset and a clock controller.
+
+Please refer to clock-bindings.txt for common clock controller binding usage.
+Please also refer to reset.txt for common reset controller binding usage.
+
+Required properties:
+- compatible: Should be:
+ "st,stm32f42xx-rcc"
+ "st,stm32f469-rcc"
+ "st,stm32f746-rcc"
+ "st,stm32f769-rcc"
+
+- reg: should be register base and length as documented in the
+ datasheet
+- #reset-cells: 1, see below
+- #clock-cells: 2, device nodes should specify the clock in their "clocks"
+ property, containing a phandle to the clock device node, an index selecting
+ between gated clocks and other clocks and an index specifying the clock to
+ use.
+- clocks: External oscillator clock phandle
+ - high speed external clock signal (HSE)
+ - external I2S clock (I2S_CKIN)
+
+Example:
+
+ rcc: rcc@40023800 {
+ #reset-cells = <1>;
+ #clock-cells = <2>
+ compatible = "st,stm32f42xx-rcc", "st,stm32-rcc";
+ reg = <0x40023800 0x400>;
+ clocks = <&clk_hse>, <&clk_i2s_ckin>;
+ };
+
+Specifying gated clocks
+=======================
+
+The primary index must be set to 0.
+
+The secondary index is the bit number within the RCC register bank, starting
+from the first RCC clock enable register (RCC_AHB1ENR, address offset 0x30).
+
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register (LSB is 0, MSB is 31).
+
+To simplify the usage and to share bit definition with the reset and clock
+drivers of the RCC IP, macros are available to generate the index in
+human-readble format.
+
+For STM32F4 series, the macro are available here:
+ - include/dt-bindings/mfd/stm32f4-rcc.h
+
+Example:
+
+ /* Gated clock, AHB1 bit 0 (GPIOA) */
+ ... {
+ clocks = <&rcc 0 STM32F4_AHB1_CLOCK(GPIOA)>
+ };
+
+ /* Gated clock, AHB2 bit 4 (CRYP) */
+ ... {
+ clocks = <&rcc 0 STM32F4_AHB2_CLOCK(CRYP)>
+ };
+
+Specifying other clocks
+=======================
+
+The primary index must be set to 1.
+
+The secondary index is bound with the following magic numbers:
+
+ 0 SYSTICK
+ 1 FCLK
+ 2 CLK_LSI (low-power clock source)
+ 3 CLK_LSE (generated from a 32.768 kHz low-speed external
+ crystal or ceramic resonator)
+ 4 CLK_HSE_RTC (HSE division factor for RTC clock)
+ 5 CLK_RTC (real-time clock)
+ 6 PLL_VCO_I2S (vco frequency of I2S pll)
+ 7 PLL_VCO_SAI (vco frequency of SAI pll)
+ 8 CLK_LCD (LCD-TFT)
+ 9 CLK_I2S (I2S clocks)
+ 10 CLK_SAI1 (audio clocks)
+ 11 CLK_SAI2
+ 12 CLK_I2SQ_PDIV (post divisor of pll i2s q divisor)
+ 13 CLK_SAIQ_PDIV (post divisor of pll sai q divisor)
+
+ 14 CLK_HSI (Internal ocscillator clock)
+ 15 CLK_SYSCLK (System Clock)
+ 16 CLK_HDMI_CEC (HDMI-CEC clock)
+ 17 CLK_SPDIF (SPDIF-Rx clock)
+ 18 CLK_USART1 (U(s)arts clocks)
+ 19 CLK_USART2
+ 20 CLK_USART3
+ 21 CLK_UART4
+ 22 CLK_UART5
+ 23 CLK_USART6
+ 24 CLK_UART7
+ 25 CLK_UART8
+ 26 CLK_I2C1 (I2S clocks)
+ 27 CLK_I2C2
+ 28 CLK_I2C3
+ 29 CLK_I2C4
+ 30 CLK_LPTIMER (LPTimer1 clock)
+ 31 CLK_PLL_SRC
+ 32 CLK_DFSDM1
+ 33 CLK_ADFSDM1
+ 34 CLK_F769_DSI
+)
+
+Example:
+
+ /* Misc clock, FCLK */
+ ... {
+ clocks = <&rcc 1 STM32F4_APB1_CLOCK(TIM2)>
+ };
+
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+For example, for CRC reset:
+ crc = AHB1RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x10 / 4 * 32 + 12 = 140
+
+example:
+
+ timer2 {
+ resets = <&rcc STM32F4_APB1_RESET(TIM2)>;
+ };

+description: |
+ The RCC IP is both a reset and a clock controller.
+ RCC makes also power management (resume/supend and wakeup interrupt).
+ Please also refer to reset.txt for common reset controller binding usage.
+
+ This binding uses common clock bindings
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+ Specifying clocks
+ =================
+
+ All available clocks are defined as preprocessor macros in
+ dt-bindings/clock/stm32mp1-clks.h header and can be used in device
+ tree sources.
+
+ Specifying softreset control of devices
+ =======================================
+
+ Device nodes should specify the reset channel required in their "resets"
+ property, containing a phandle to the reset device node and an index specifying

+ The index is the bit number within the RCC registers bank, starting from RCC
+ base address.
+ It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+ Where bit_offset is the bit offset within the register.
+
+ For example on STM32MP1, for LTDC reset:
+ ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset
+ = 0x180 / 4 * 32 + 0 = 3072
+
+ The list of valid indices for STM32MP1 is available in:

+certain STMicroelectronics consumer electronics SoC devices.
+
+This version contains a programmable PLL which can generate up to 216, 432
+or 660MHz (from a 30MHz oscillator input) as the input to the digital
+synthesizers.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be:
+ "st,quadfs"
+ "st,quadfs-d0"
+ "st,quadfs-d2"
+ "st,quadfs-d3"
+ "st,quadfs-pll"
+
+
+- #clock-cells : from common clock binding; shall be set to 1.
+
+- reg : A Base address and length of the register set.
+
+- clocks : from common clock binding
+
+- clock-output-names : From common clock binding. The block has 4
+ clock outputs but not all of them in a specific instance
+ have to be used in the SoC. If a clock name is left as
+ an empty string then no clock will be created for the
+ output associated with that string index. If fewer than
+ 4 strings are provided then no clocks will be created
+ for the remaining outputs.
+
+Example:
+
+ clk_s_c0_quadfs: clk-s-c0-quadfs@9103000 {
+ #clock-cells = <1>;
+ compatible = "st,quadfs-pll";
+ reg = <0x9103000 0x1000>;
+
+ clocks = <&clk_sysin>;
+
+ clock-output-names = "clk-s-c0-fs0-ch0",
+ "clk-s-c0-fs0-ch1",
+ "clk-s-c0-fs0-ch2",
+ "clk-s-c0-fs0-ch3";
+ };

+description: While named "U8500 clocks" these clocks are inside the
+ DB8500 digital baseband system-on-chip and its siblings such as
+ DB8520. These bindings consider the clocks present in the SoC
+ itself, not off-chip clocks. There are four different on-chip
+ clocks - RTC (32 kHz), CPU clock (SMP TWD), PRCMU (power reset and
+ control management unit) clocks and PRCC (peripheral reset and
+ clock controller) clocks. For some reason PRCC 4 does not exist so
+ the itemization can be a bit unintuitive.

+Texas Instruments clkctrl clock binding
+
+Texas Instruments SoCs can have a clkctrl clock controller for each
+interconnect target module. The clkctrl clock controller manages functional
+and interface clocks for each module. Each clkctrl controller can also
+gate one or more optional functional clocks for a module, and can have one
+or more clock muxes. There is a clkctrl clock controller typically for each
+interconnect target module on omap4 and later variants.
+
+The clock consumers can specify the index of the clkctrl clock using
+the hardware offset from the clkctrl instance register space. The optional
+clocks can be specified by clkctrl hardware offset and the index of the
+optional clock.
+
+For more information, please see the Linux clock framework binding at
+Documentation/devicetree/bindings/clock/clock-bindings.txt.
+
+Required properties :
+- compatible : shall be "ti,clkctrl" or a clock domain specific name:
+ "ti,clkctrl-l4-cfg"
+ "ti,clkctrl-l4-per"
+ "ti,clkctrl-l4-secure"
+ "ti,clkctrl-l4-wkup"
+- clock-output-names : from common clock binding
+- #clock-cells : shall contain 2 with the first entry being the instance
+ offset from the clock domain base and the second being the
+ clock index
+- reg : clock registers
+
+Example: Clock controller node on omap 4430:
+
+&cm2 {
+ l4per: cm@1400 {
+ cm_l4per@0 {
+ cm_l4per_clkctrl: clock@20 {

+ clock-output-names = "l4_per";
+ reg = <0x20 0x1b0>;
+ #clock-cells = <2>;
+ };
+ };
+ };
+};
+
+Example: Preprocessor helper macros in dt-bindings/clock/ti-clkctrl.h
+
+#define OMAP4_CLKCTRL_OFFSET 0x20
+#define OMAP4_CLKCTRL_INDEX(offset) ((offset) - OMAP4_CLKCTRL_OFFSET)
+#define MODULEMODE_HWCTRL 1
+#define MODULEMODE_SWCTRL 2

+Binding for TI divider clock
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped adjustable clock rate divider that does not gate and has
+only one input clock or parent. By default the value programmed into
+the register is one less than the actual divisor value. E.g:
+
+register value actual divisor value
+0 1
+1 2
+2 3
+
+This assumption may be modified by the following optional properties:
+
+ti,index-starts-at-one - valid divisor values start at 1, not the default
+of 0. E.g:
+register value actual divisor value
+1 1
+2 2
+3 3
+
+ti,index-power-of-two - valid divisor values are powers of two. E.g:
+register value actual divisor value
+0 1
+1 2
+2 4
+
+Additionally an array of valid dividers may be supplied like so:
+
+ ti,dividers = <4>, <8>, <0>, <16>;
+
+Which will map the resulting values to a divisor table by their index:
+register value actual divisor value
+0 4
+1 8
+2 <invalid divisor, skipped>
+3 16
+
+Any zero value in this array means the corresponding bit-value is invalid
+and must not be used.
+
+The binding must also provide the register to control the divider and
+unless the divider array is provided, min and max dividers. Optionally
+the number of bits to shift that mask, if necessary. If the shift value
+is missing it is the same as supplying a zero shift.
+
+This binding can also optionally provide support to the hardware autoidle
+feature, see [2].

+- ti,bit-shift : number of bits to shift the divider value, defaults to 0

+- ti,max-div : max divisor for dividing the input clock rate, only needed
+ if ti,dividers is not defined.
+- ti,index-starts-at-one : valid divisor programming starts at 1, not zero,
+ only valid if ti,dividers is not defined.
+- ti,index-power-of-two : valid divisor programming must be a power of two,
+ only valid if ti,dividers is not defined.
+- ti,autoidle-shift : bit shift of the autoidle enable bit for the clock,
+ see [2]
+- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0,
+ see [2]
+- ti,set-rate-parent : clk_set_rate is propagated to parent

+Binding for TI mux clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped multiplexer with multiple input clock signals or
+parents, one of which can be selected as output. This clock does not
+gate or adjust the parent rate via a divider or multiplier.
+
+By default the "clocks" property lists the parents in the same order
+as they are programmed into the register. E.g:
+
+ clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
+
+results in programming the register as follows:
+
+register value selected parent clock
+0 foo_clock
+1 bar_clock
+2 baz_clock
+
+Some clock controller IPs do not allow a value of zero to be programmed
+into the register, instead indexing begins at 1. The optional property
+"index-starts-at-one" modified the scheme as follows:
+
+register value selected clock parent
+1 foo_clock
+2 bar_clock
+3 baz_clock
+
+The binding must provide the register to control the mux. Optionally
+the number of bits to shift the control field in the register can be
+supplied. If the shift value is missing it is the same as supplying
+a zero shift.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "ti,mux-clock" or "ti,composite-mux-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks
+- reg : register offset for register controlling adjustable mux
+
+Optional properties:
+- clock-output-names : from common clock binding.
+- ti,bit-shift : number of bits to shift the bit-mask, defaults to
+ 0 if not present
+- ti,index-starts-at-one : valid input select programming starts at 1, not
+ zero
+- ti,set-rate-parent : clk_set_rate is propagated to parent clock,
+ not supported by the composite-mux-clock subtype
+- ti,latch-bit : latch the mux value to HW, only needed if the register
+ access requires this. As an example, dra7x DPLL_GMAC H14 muxing
+ implements such behavior.

+Device Tree Clock bindings for the Zynq 7000 EPP
+
+The Zynq EPP has several different clk providers, each with there own bindings.
+The purpose of this document is to document their usage.
+
+See clock_bindings.txt for more information on the generic clock bindings.
+See Chapter 25 of Zynq TRM for more information about Zynq clocks.
+
+== Clock Controller ==
+The clock controller is a logical abstraction of Zynq's clock tree. It reads
+required input clock frequencies from the devicetree and acts as clock provider
+for all clock consumers of PS clocks.
+
+Required properties:
+ - #clock-cells : Must be 1
+ - compatible : "xlnx,ps7-clkc"
+ - reg : SLCR offset and size taken via syscon < 0x100 0x100 >
+ - ps-clk-frequency : Frequency of the oscillator providing ps_clk in HZ
+ (usually 33 MHz oscillators are used for Zynq platforms)
+ - clock-output-names : List of strings used to name the clock outputs. Shall be
+ a list of the outputs given below.
+
+Optional properties:
+ - clocks : as described in the clock bindings
+ - clock-names : as described in the clock bindings
+ - fclk-enable : Bit mask to enable FCLKs statically at boot time.
+ Bit [0..3] correspond to FCLK0..FCLK3. The corresponding
+ FCLK will only be enabled if it is actually running at
+ boot time.
+
+Clock inputs:
+The following strings are optional parameters to the 'clock-names' property in
+order to provide an optional (E)MIO clock source.
+ - swdt_ext_clk
+ - gem0_emio_clk
+ - gem1_emio_clk

+Common properties
+=================
+
+Endianness
+----------
+
+The Devicetree Specification does not define any properties related to hardware
+byte swapping, but endianness issues show up frequently in porting drivers to
+different machine types. This document attempts to provide a consistent
+way of handling byte swapping across drivers.
+
+Optional properties:
+ - big-endian: Boolean; force big endian register accesses
+ unconditionally (e.g. ioread32be/iowrite32be). Use this if you
+ know the peripheral always needs to be accessed in big endian (BE) mode.
+ - little-endian: Boolean; force little endian register accesses
+ unconditionally (e.g. readl/writel). Use this if you know the
+ peripheral always needs to be accessed in little endian (LE) mode.
+ - native-endian: Boolean; always use register accesses matched to the
+ endianness of the kernel binary (e.g. LE vmlinux -> readl/writel,
+ BE vmlinux -> ioread32be/iowrite32be). In this case no byte swaps
+ will ever be performed. Use this if the hardware "self-adjusts"
+ register endianness based on the CPU's configured endianness.
+
+If a binding supports these properties, then the binding should also
+specify the default behavior if none of these properties are present.
+In such cases, little-endian is the preferred default, but it is not
+a requirement. Some implementations assume that little-endian is
+the default, because most existing (PCI-based) drivers implicitly
+default to LE for their MMIO accesses.
+
+Examples:
+Scenario 1 : CPU in LE mode & device in LE mode.
+dev: dev@40031000 {
+ compatible = "name";
+ reg = <0x40031000 0x1000>;
+ ...
+ native-endian;
+};
+
+Scenario 2 : CPU in LE mode & device in BE mode.
+dev: dev@40031000 {
+ compatible = "name";
+ reg = <0x40031000 0x1000>;
+ ...
+ big-endian;
+};
+
+Scenario 3 : CPU in BE mode & device in BE mode.
+dev: dev@40031000 {
+ compatible = "name";
+ reg = <0x40031000 0x1000>;
+ ...
+ native-endian;
+};
+
+Scenario 4 : CPU in BE mode & device in LE mode.
+dev: dev@40031000 {
+ compatible = "name";
+ reg = <0x40031000 0x1000>;
+ ...
+ little-endian;
+};
+
+Daisy-chained devices
+---------------------
+
+Many serially-attached GPIO and IIO devices are daisy-chainable. To the
+host controller, a daisy-chain appears as a single device, but the number
+of inputs and outputs it provides is the sum of inputs and outputs provided
+by all of its devices. The driver needs to know how many devices the
+daisy-chain comprises to determine the amount of data exchanged, how many
+inputs and outputs to register and so on.
+
+Optional properties:
+ - #daisy-chained-devices: Number of devices in the daisy-chain (default is 1).
+
+Example:
+gpio@0 {
+ compatible = "name";
+ reg = <0>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ #daisy-chained-devices = <3>;
+};

+==========================================
+CPU capacity bindings
+==========================================
+
+==========================================
+1 - Introduction
+==========================================
+
+Some systems may be configured to have cpus with different power/performance
+characteristics within the same chip. In this case, additional information has
+to be made available to the kernel for it to be aware of such differences and
+take decisions accordingly.
+
+==========================================
+2 - CPU capacity definition
+==========================================
+
+CPU capacity is a number that provides the scheduler information about CPUs
+heterogeneity. Such heterogeneity can come from micro-architectural differences
+(e.g., ARM big.LITTLE systems) or maximum frequency at which CPUs can run
+(e.g., SMP systems with multiple frequency domains). Heterogeneity in this
+context is about differing performance characteristics; this binding tries to
+capture a first-order approximation of the relative performance of CPUs.
+
+CPU capacities are obtained by running a suitable benchmark. This binding makes
+no guarantees on the validity or suitability of any particular benchmark, the
+final capacity should, however, be:
+
+* A "single-threaded" or CPU affine benchmark
+* Divided by the running frequency of the CPU executing the benchmark
+* Not subject to dynamic frequency scaling of the CPU
+
+For the time being we however advise usage of the Dhrystone benchmark. What
+above thus becomes:
+
+CPU capacities are obtained by running the Dhrystone benchmark on each CPU at
+max frequency (with caches enabled). The obtained DMIPS score is then divided
+by the frequency (in MHz) at which the benchmark has been run, so that
+DMIPS/MHz are obtained. Such values are then normalized w.r.t. the highest
+score obtained in the system.
+
+==========================================
+3 - capacity-dmips-mhz
+==========================================
+
+capacity-dmips-mhz is an optional cpu node [1] property: u32 value
+representing CPU capacity expressed in normalized DMIPS/MHz. At boot time, the
+maximum frequency available to the cpu is then used to calculate the capacity
+value internally used by the kernel.
+
+capacity-dmips-mhz property is all-or-nothing: if it is specified for a cpu
+node, it has to be specified for every other cpu nodes, or the system will
+fall back to the default capacity value for every CPU. If cpufreq is not
+available, final capacities are calculated by directly using capacity-dmips-
+mhz values (normalized w.r.t. the highest value found while parsing the DT).
+
+===========================================
+4 - Examples
+===========================================
+
+Example 1 (ARM 64-bit, 6-cpu system, two clusters):
+The capacities-dmips-mhz or DMIPS/MHz values (scaled to 1024)
+are 1024 and 578 for cluster0 and cluster1. Further normalization
+is done by the operating system based on cluster0@max-freq=1100 and
+cluster1@max-freq=850, final capacities are 1024 for cluster0 and
+446 for cluster1 (578*850/1100).

+===========================================
+CPU topology binding description
+===========================================
+
+===========================================
+1 - Introduction
+===========================================
+
+In a SMP system, the hierarchy of CPUs is defined through three entities that
+are used to describe the layout of physical CPUs in the system:
+
+- socket
+- cluster
+- core
+- thread
+
+The bottom hierarchy level sits at core or thread level depending on whether
+symmetric multi-threading (SMT) is supported or not.
+
+For instance in a system where CPUs support SMT, "cpu" nodes represent all
+threads existing in the system and map to the hierarchy level "thread" above.
+In systems where SMT is not supported "cpu" nodes represent all cores present
+in the system and map to the hierarchy level "core" above.
+
+CPU topology bindings allow one to associate cpu nodes with hierarchical groups
+corresponding to the system hierarchy; syntactically they are defined as device
+tree nodes.
+
+Currently, only ARM/RISC-V intend to use this cpu topology binding but it may be
+used for any other architecture as well.
+
+The cpu nodes, as per bindings defined in [4], represent the devices that
+correspond to physical CPUs and are to be mapped to the hierarchy levels.
+
+A topology description containing phandles to cpu nodes that are not compliant
+with bindings standardized in [4] is therefore considered invalid.
+
+===========================================
+2 - cpu-map node
+===========================================
+
+The ARM/RISC-V CPU topology is defined within the cpu-map node, which is a direct
+child of the cpus node and provides a container where the actual topology
+nodes are listed.
+
+- cpu-map node
+
+ Usage: Optional - On SMP systems provide CPUs topology to the OS.
+ Uniprocessor systems do not require a topology
+ description and therefore should not define a
+ cpu-map node.
+
+ Description: The cpu-map node is just a container node where its
+ subnodes describe the CPU topology.
+
+ Node name must be "cpu-map".
+
+ The cpu-map node's parent node must be the cpus node.
+
+ The cpu-map node's child nodes can be:
+
+ - one or more cluster nodes or
+ - one or more socket nodes in a multi-socket system
+
+ Any other configuration is considered invalid.
+
+The cpu-map node can only contain 4 types of child nodes:
+
+- socket node
+- cluster node
+- core node
+- thread node
+
+whose bindings are described in paragraph 3.
+
+The nodes describing the CPU topology (socket/cluster/core/thread) can
+only be defined within the cpu-map node and every core/thread in the
+system must be defined within the topology. Any other configuration is
+invalid and therefore must be ignored.
+
+===========================================
+2.1 - cpu-map child nodes naming convention
+===========================================
+
+cpu-map child nodes must follow a naming convention where the node name
+must be "socketN", "clusterN", "coreN", "threadN" depending on the node type
+(ie socket/cluster/core/thread) (where N = {0, 1, ...} is the node number; nodes
+which are siblings within a single common parent node must be given a unique and
+sequential N value, starting from 0).
+cpu-map child nodes which do not share a common parent node can have the same
+name (ie same number N as other cpu-map child nodes at different device tree
+levels) since name uniqueness will be guaranteed by the device tree hierarchy.

+3 - socket/cluster/core/thread node bindings
+===========================================
+
+Bindings for socket/cluster/cpu/thread nodes are defined as follows:
+
+- socket node
+
+ Description: must be declared within a cpu-map node, one node
+ per physical socket in the system. A system can
+ contain single or multiple physical socket.
+ The association of sockets and NUMA nodes is beyond
+ the scope of this bindings, please refer [2] for
+ NUMA bindings.
+
+ This node is optional for a single socket system.
+
+ The socket node name must be "socketN" as described in 2.1 above.
+ A socket node can not be a leaf node.
+
+ A socket node's child nodes must be one or more cluster nodes.
+
+ Any other configuration is considered invalid.
+
+- cluster node
+
+ Description: must be declared within a cpu-map node, one node
+ per cluster. A system can contain several layers of
+ clustering within a single physical socket and cluster
+ nodes can be contained in parent cluster nodes.
+
+ The cluster node name must be "clusterN" as described in 2.1 above.
+ A cluster node can not be a leaf node.
+
+ A cluster node's child nodes must be:
+
+ - one or more cluster nodes; or
+ - one or more core nodes
+
+ Any other configuration is considered invalid.
+
+- core node
+
+ Description: must be declared in a cluster node, one node per core in
+ the cluster. If the system does not support SMT, core
+ nodes are leaf nodes, otherwise they become containers of
+ thread nodes.
+
+ The core node name must be "coreN" as described in 2.1 above.
+
+ A core node must be a leaf node if SMT is not supported.
+
+ Properties for core nodes that are leaf nodes:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to the
+ core node.
+
+ If a core node is not a leaf node (CPUs supporting SMT) a core node's
+ child nodes can be:
+
+ - one or more thread nodes
+
+ Any other configuration is considered invalid.
+
+- thread node
+
+ Description: must be declared in a core node, one node per thread
+ in the core if the system supports SMT. Thread nodes are
+ always leaf nodes in the device tree.
+
+ The thread node name must be "threadN" as described in 2.1 above.
+
+ A thread node must be a leaf node.
+
+ A thread node must contain the following property:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to
+ the thread node.

+ ==========================================
+ 1 - Introduction
+ ==========================================
+
+ ARM and RISC-V systems contain HW capable of managing power consumption
+ dynamically, where cores can be put in different low-power states (ranging
+ from simple wfi to power gating) according to OS PM policies. The CPU states
+ representing the range of dynamic idle states that a processor can enter at
+ run-time, can be specified through device tree bindings representing the
+ parameters required to enter/exit specific idle states on a given processor.
+
+ ==========================================
+ 2 - ARM idle states
+ ==========================================
+
+ According to the Server Base System Architecture document (SBSA, [3]), the
+ power states an ARM CPU can be put into are identified by the following list:
+
+ - Running
+ - Idle_standby
+ - Idle_retention
+ - Sleep
+ - Off
+
+ The power states described in the SBSA document define the basic CPU states on
+ top of which ARM platforms implement power management schemes that allow an OS
+ PM implementation to put the processor in different idle states (which include
+ states listed above; "off" state is not an idle state since it does not have
+ wake-up capabilities, hence it is not considered in this document).
+
+ Idle state parameters (e.g. entry latency) are platform specific and need to
+ be characterized with bindings that provide the required information to OS PM
+ code so that it can build the required tables and use them at runtime.
+
+ The device tree binding definition for ARM idle states is the subject of this
+ document.
+
+ ==========================================
+ 3 - RISC-V idle states
+ ==========================================
+
+ On RISC-V systems, the HARTs (or CPUs) [6] can be put in platform specific
+ suspend (or idle) states (ranging from simple WFI, power gating, etc). The
+ RISC-V SBI v0.3 (or higher) [7] hart state management extension provides a
+ standard mechanism for OS to request HART state transitions.
+
+ The platform specific suspend (or idle) states of a hart can be either
+ retentive or non-rententive in nature. A retentive suspend state will
+ preserve HART registers and CSR values for all privilege modes whereas
+ a non-retentive suspend state will not preserve HART registers and CSR
+ values.
+
+ ===========================================
+ 4 - idle-states definitions
+ ===========================================
+
+ Idle states are characterized for a specific system through a set of
+ timing and energy related properties, that underline the HW behaviour
+ triggered upon idle states entry and exit.
+
+ The following diagram depicts the CPU execution phases and related timing
+ properties required to enter and exit an idle state:
+
+ ..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
+ | | | | |
+
+ |<------ entry ------->|
+ | latency |
+ |<- exit ->|
+ | latency |
+ |<-------- min-residency -------->|
+ |<------- wakeup-latency ------->|
+
+ Diagram 1: CPU idle state execution phases
+
+ EXEC: Normal CPU execution.
+
+ PREP: Preparation phase before committing the hardware to idle mode
+ like cache flushing. This is abortable on pending wake-up
+ event conditions. The abort latency is assumed to be negligible
+ (i.e. less than the ENTRY + EXIT duration). If aborted, CPU
+ goes back to EXEC. This phase is optional. If not abortable,
+ this should be included in the ENTRY phase instead.
+
+ ENTRY: The hardware is committed to idle mode. This period must run
+ to completion up to IDLE before anything else can happen.
+
+ IDLE: This is the actual energy-saving idle period. This may last
+ between 0 and infinite time, until a wake-up event occurs.
+
+ EXIT: Period during which the CPU is brought back to operational
+ mode (EXEC).
+
+ entry-latency: Worst case latency required to enter the idle state. The
+ exit-latency may be guaranteed only after entry-latency has passed.
+
+ min-residency: Minimum period, including preparation and entry, for a given
+ idle state to be worthwhile energywise.
+
+ wakeup-latency: Maximum delay between the signaling of a wake-up event and the
+ CPU being able to execute normal code again. If not specified, this is assumed
+ to be entry-latency + exit-latency.
+
+ These timing parameters can be used by an OS in different circumstances.
+
+ An idle CPU requires the expected min-residency time to select the most
+ appropriate idle state based on the expected expiry time of the next IRQ
+ (i.e. wake-up) that causes the CPU to return to the EXEC phase.
+
+ An operating system scheduler may need to compute the shortest wake-up delay
+ for CPUs in the system by detecting how long will it take to get a CPU out
+ of an idle state, e.g.:
+
+ wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
+
+ In other words, the scheduler can make its scheduling decision by selecting
+ (e.g. waking-up) the CPU with the shortest wake-up delay.
+ The wake-up delay must take into account the entry latency if that period
+ has not expired. The abortable nature of the PREP period can be ignored
+ if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
+ the worst case since it depends on the CPU operating conditions, i.e. caches
+ state).
+
+ An OS has to reliably probe the wakeup-latency since some devices can enforce
+ latency constraint guarantees to work properly, so the OS has to detect the
+ worst case wake-up latency it can incur if a CPU is allowed to enter an
+ idle state, and possibly to prevent that to guarantee reliable device
+ functioning.
+
+ The min-residency time parameter deserves further explanation since it is
+ expressed in time units but must factor in energy consumption coefficients.
+
+ The energy consumption of a cpu when it enters a power state can be roughly
+ characterised by the following graph:
+
+ |
+ |
+ |
+ e |
+ n | /---
+ e | /------
+ r | /------
+ g | /-----
+ y | /------
+ | ----
+ | /|
+ | / |
+ | / |
+ | / |
+ | / |
+ | / |
+ |/ |
+ -----|-------+----------------------------------
+ 0| 1 time(ms)
+
+ Graph 1: Energy vs time example
+
+ The graph is split in two parts delimited by time 1ms on the X-axis.
+ The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
+ and denotes the energy costs incurred while entering and leaving the idle
+ state.
+ The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
+ shallower slope and essentially represents the energy consumption of the idle
+ state.
+
+ min-residency is defined for a given idle state as the minimum expected
+ residency time for a state (inclusive of preparation and entry) after
+ which choosing that state become the most energy efficient option. A good
+ way to visualise this, is by taking the same graph above and comparing some
+ states energy consumptions plots.
+
+ For sake of simplicity, let's consider a system with two idle states IDLE1,
+ and IDLE2:
+
+ |
+ |
+ |
+ | /-- IDLE1
+ e | /---
+ n | /----
+ e | /---
+ r | /-----/--------- IDLE2
+ g | /-------/---------
+ y | ------------ /---|
+ | / /---- |
+ | / /--- |
+ | / /---- |
+ | / /--- |
+ | --- |
+ | / |
+ | / |
+ |/ | time
+ ---/----------------------------+------------------------
+ |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
+ |
+ IDLE2-min-residency
+
+ Graph 2: idle states min-residency example
+
+ In graph 2 above, that takes into account idle states entry/exit energy
+ costs, it is clear that if the idle state residency time (i.e. time till next
+ wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
+ choice energywise.
+
+ This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
+ than IDLE2.
+
+ However, the lower power consumption (i.e. shallower energy curve slope) of
+ idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
+ efficient.
+
+ The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
+ shallower states in a system with multiple idle states) is defined
+ IDLE2-min-residency and corresponds to the time when energy consumption of
+ IDLE1 and IDLE2 states breaks even.
+
+ The definitions provided in this section underpin the idle states
+ properties specification that is the subject of the following sections.
+
+ ===========================================
+ 5 - idle-states node
+ ===========================================
+
+ The processor idle states are defined within the idle-states node, which is
+ a direct child of the cpus node [1] and provides a container where the
+ processor idle states, defined as device tree nodes, are listed.
+
+ On ARM systems, it is a container of processor idle states nodes. If the
+ system does not provide CPU power management capabilities, or the processor
+ just supports idle_standby, an idle-states node is not required.

+references the mailbox register used to communicate with the AVS CPU[1]. The
+second node (brcm,avs-cpu-l2-intr) is required to trigger an interrupt on
+the AVS CPU. The interrupt tells the AVS CPU that it needs to process a
+command sent to it by a driver. Interrupting the AVS CPU is mandatory for
+commands to be processed.
+
+The interface also requires a reference to the AVS host interrupt controller,
+so a driver can react to interrupts generated by the AVS CPU whenever a command
+has been processed. See [2] for more information on the brcm,l2-intc node.
+
+[1] The AVS CPU is an independent co-processor that runs proprietary
+firmware. On some SoCs, this firmware supports DFS and DVFS in addition to
+Adaptive Voltage Scaling.

+Generic cpufreq driver
+
+It is a generic DT based cpufreq driver for frequency management. It supports
+both uniprocessor (UP) and symmetric multiprocessor (SMP) systems which share
+clock and voltage across all CPUs.
+
+Both required and optional properties listed below must be defined

+
+Required properties:
+- None
+
+Optional properties:
+- operating-points: Refer to Documentation/devicetree/bindings/opp/opp-v1.yaml for

+Binding for MediaTek's CPUFreq driver
+=====================================
+
+Required properties:
+- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
+- clock-names: Should contain the following:
+ "cpu" - The multiplexer for clock input of CPU cluster.
+ "intermediate" - A parent of "cpu" clock which is used as "intermediate" clock
+ source (usually MAINPLL) when the original CPU PLL is under
+ transition and not stable yet.
+ Please refer to Documentation/devicetree/bindings/clock/clock-bindings.txt for
+ generic clock consumer properties.
+- operating-points-v2: Please refer to Documentation/devicetree/bindings/opp/opp-v2.yaml
+ for detail.
+- proc-supply: Regulator for Vproc of CPU cluster.
+
+Optional properties:
+- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
+ needs to do "voltage tracking" to step by step scale up/down Vproc and
+ Vsram to fit SoC specific needs. When absent, the voltage scaling
+ flow is handled by hardware, hence no software "voltage tracking" is
+ needed.
+- mediatek,cci:
+ Used to confirm the link status between cpufreq and mediatek cci. Because
+ cpufreq and mediatek cci could share the same regulator in some MediaTek SoCs.
+ To prevent the issue of high frequency and low voltage, we need to use this
+ property to make sure mediatek cci is ready.
+ For details of mediatek cci, please refer to
+ Documentation/devicetree/bindings/interconnect/mediatek,cci.yaml
+- #cooling-cells:
+ For details, please refer to
+ Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml

+Binding for ST's CPUFreq driver
+===============================
+
+ST's CPUFreq driver attempts to read 'process' and 'version' attributes
+from the SoC, then supplies the OPP framework with 'prop' and 'supported
+hardware' information respectively. The framework is then able to read
+the DT and operate in the usual way.
+
+Frequency Scaling only
+----------------------
+
+No vendor specific driver required for this.
+
+Located in CPU's node:
+
+- operating-points : [See: ../power/opp-v1.yaml]

+Example [safe]
+--------------
+
+cpus {
+ cpu@0 {
+ /* kHz uV */
+ operating-points = <1500000 0
+ 1200000 0
+ 800000 0

+i.MX CPUFreq-DT OPP bindings
+================================
+
+Certain i.MX SoCs support different OPPs depending on the "market segment" and
+"speed grading" value which are written in fuses. These bits are combined with
+the opp-supported-hw values for each OPP to check if the OPP is allowed.
+
+Required properties:
+--------------------
+
+For each opp entry in 'operating-points-v2' table:
+- opp-supported-hw: Two bitmaps indicating:
+ - Supported speed grade mask
+ - Supported market segment mask
+ 0: Consumer
+ 1: Extended Consumer
+ 2: Industrial
+ 3: Automotive
+
+Example:
+--------
+
+opp_table {
+ compatible = "operating-points-v2";
+ opp-1000000000 {
+ opp-hz = /bits/ 64 <1000000000>;

+
+Required properties:
+- compatible: Should be one of the following:
+ brcm,spum-crypto - for devices with SPU-M hardware
+ brcm,spu2-crypto - for devices with SPU2 hardware
+ brcm,spu2-v2-crypto - for devices with enhanced SPU2 hardware features like SHA3
+ and Rabin Fingerprint support
+ brcm,spum-nsp-crypto - for the Northstar Plus variant of the SPU-M hardware
+
+- reg: Should contain SPU registers location and length.
+- mboxes: The mailbox channel to be used to communicate with the SPU.
+ Mailbox channels correspond to DMA rings on the device.
+
+Example:
+ crypto@612d0000 {

+description: |
+ NOTE: the SEC 4 is also known as Freescale's Cryptographic Accelerator
+ Accelerator and Assurance Module (CAAM).
+
+ SEC 4 h/w can process requests from 2 types of sources.
+ 1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
+ 2. Job Rings (HW interface between cores & SEC 4 registers).
+
+ High Speed Data Path Configuration:
+
+ HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
+ such as the P4080. The number of simultaneous dequeues the QI can make is
+ equal to the number of Descriptor Controller (DECO) engines in a particular
+ SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
+ dequeue from 5 subportals simultaneously.
+
+ Job Ring Data Path Configuration:
+
+ Each JR is located on a separate 4k page, they may (or may not) be made visible
+ in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
+ up to 4 JRs can be configured; and all 4 JRs process requests in parallel.

+Since some chips may contain more than one SEC, the dtsi contains
+only the node contents, not the node itself. A chip using the SEC
+should include the dtsi inside each SEC node. Example:
+
+In qoriq-sec6.0.dtsi:
+
+ compatible = "fsl,sec-v6.0";
+ fsl,sec-era = <6>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ jr@1000 {
+ compatible = "fsl,sec-v6.0-job-ring",
+ "fsl,sec-v5.2-job-ring",
+ "fsl,sec-v5.0-job-ring",
+ "fsl,sec-v4.4-job-ring",
+ "fsl,sec-v4.0-job-ring";
+ reg = <0x1000 0x1000>;
+ };
+
+ jr@2000 {
+ compatible = "fsl,sec-v6.0-job-ring",
+ "fsl,sec-v5.2-job-ring",
+ "fsl,sec-v5.0-job-ring",
+ "fsl,sec-v4.4-job-ring",
+ "fsl,sec-v4.0-job-ring";
+ reg = <0x2000 0x1000>;
+ };
+
+In the C293 device tree, we add the include of public property:
+
+ crypto@a0000 {
+ /include/ "qoriq-sec6.0.dtsi"
+ }
+
+ crypto@a0000 {

+OMAP SoC SHA crypto Module
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+ SHAM versions:
+ - "ti,omap2-sham" for OMAP2 & OMAP3.
+ - "ti,omap4-sham" for OMAP4 and AM33XX.
+ - "ti,omap5-sham" for OMAP5, DRA7 and AM43XX.
+- ti,hwmods: Name of the hwmod associated with the SHAM module
+- reg : Offset and length of the register set for the module
+- interrupts : the interrupt-specifier for the SHAM module.
+
+Optional properties:
+- dmas: DMA specifiers for the rx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: DMA request name. Should be "rx" if a dma is present.
+
+Example:
+ /* AM335x */
+ sham: sham@53100000 {
+ compatible = "ti,omap4-sham";
+ ti,hwmods = "sham";
+ reg = <0x53100000 0x200>;
+ interrupts = <109>;
+ dmas = <&edma 36>;
+ dma-names = "rx";

+C-SKY CPU Bindings
+==================
+
+The device tree allows to describe the layout of CPUs in a system through
+the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+defining properties for every cpu.
+
+Only SMP system need to care about the cpus node and single processor
+needn't define cpus node at all.
+
+=====================================
+cpus and cpu node bindings definition
+=====================================
+
+- cpus node
+
+ Description: Container of cpu nodes
+
+ The node name must be "cpus".
+
+ A cpus node must define the following properties:
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be set to 1
+ - #size-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be set to 0
+
+- cpu node
+
+ Description: Describes one of SMP cores
+
+ PROPERTIES
+
+ - device_type
+ Usage: required
+ Value type: <string>
+ Definition: must be "cpu"
+ - reg
+ Usage: required
+ Value type: <u32>
+ Definition: CPU index
+ - compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must contain "csky", eg:
+ "csky,610"
+ "csky,807"
+ "csky,810"
+ "csky,860"
+
+Example:
+--------
+
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cpu@0 {
+ device_type = "cpu";
+ reg = <0>;
+ status = "ok";
+ };
+
+ cpu@1 {
+ device_type = "cpu";
+ reg = <1>;

+
+description: |
+ The display engine pipeline (and its entry point, since it can be
+ either directly the backend or the frontend) is represented as an
+ extra node.
+
+ The Allwinner A10 Display pipeline is composed of several components
+ that are going to be documented below:
+
+ For all connections between components up to the TCONs in the
+ display pipeline, when there are multiple components of the same
+ type at the same depth, the local endpoint ID must be the same as
+ the remote component's index. For example, if the remote endpoint is
+ Frontend 1, then the local endpoint ID must be 1.
+
+ Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
+ [1] -- -- [1] [1] -- -- [1]
+ \ / \ /
+ X X
+ / \ / \
+ [0] -- -- [0] [0] -- -- [0]
+ Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
+
+ For a two pipeline system such as the one depicted above, the lines
+ represent the connections between the components, while the numbers
+ within the square brackets corresponds to the ID of the local endpoint.
+
+ The same rule also applies to DE 2.0 mixer-TCON connections:
+
+ Mixer 0 [0] ----------- [0] TCON 0
+ [1] ---- ---- [1]
+ \ /
+ X
+ / \
+ [0] ---- ---- [0]
+ Mixer 1 [1] ----------- [1] TCON 1

+description: |
+ TCON TOPs main purpose is to configure whole display pipeline. It
+ determines relationships between mixers and TCONs, selects source
+ TCON for HDMI, muxes LCD and TV encoder GPIO output, selects TV
+ encoder clock source and contains additional TV TCON and DSI gates.
+
+ It allows display pipeline to be configured in very different ways:
+
+ / LCD0/LVDS0
+ / [0] TCON-LCD0
+ | \ MIPI DSI
+ mixer0 |
+ \ / [1] TCON-LCD1 - LCD1/LVDS1
+ TCON-TOP
+ / \ [2] TCON-TV0 [0] - TVE0/RGB
+ mixer1 | \
+ | TCON-TOP - HDMI
+ | /
+ \ [3] TCON-TV1 [1] - TVE1/RGB
+
+ Note that both TCON TOP references same physical unit. Both mixers
+ can be connected to any TCON. Not all TCON TOP variants support all
+ features.

+ The Amlogic Meson Synopsys Designware Integration is composed of
+ - A Synopsys DesignWare HDMI Controller IP
+ - A TOP control block controlling the Clocks and PHY
+ - A custom HDMI PHY in order to convert video to TMDS signal
+ ___________________________________
+ | HDMI TOP |<= HPD
+ |___________________________________|
+ | | |
+ | Synopsys HDMI | HDMI PHY |=> TMDS
+ | Controller |________________|
+ |___________________________________|<=> DDC
+
+ The HDMI TOP block only supports HPD sensing.
+ The Synopsys HDMI Controller interrupt is routed through the
+ TOP Block interrupt.
+ Communication to the TOP Block and the Synopsys HDMI Controller is done
+ via a pair of dedicated addr+read/write registers.
+ The HDMI PHY is configured by registers in the HHI register block.
+
+ Pixel data arrives in "4:4:4" format from the VENC block and the VPU HDMI mux
+ selects either the ENCI encoder for the 576i or 480i formats or the ENCP
+ encoder for all the other formats including interlaced HD formats.
+
+ The VENC uses a DVI encoder on top of the ENCI or ENCP encoders to generate
+ DVI timings for the HDMI controller.
+
+ Amlogic Meson GXBB, GXL and GXM SoCs families embeds the Synopsys DesignWare
+ HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF
+ audio source interfaces.

+description: |
+ The Amlogic Meson Display controller is composed of several components
+ that are going to be documented below
+
+ DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
+ | vd1 _______ _____________ _________________ | |
+ D |-------| |----| | | | | HDMI PLL |

+ M |-------|______|----|____________| |________________| | |
+ ___|__________________________________________________________|_______________|
+
+
+ VIU: Video Input Unit
+ ---------------------
+
+ The Video Input Unit is in charge of the pixel scanout from the DDR memory.
+ It fetches the frames addresses, stride and parameters from the "Canvas" memory.
+ This part is also in charge of the CSC (Colorspace Conversion).
+ It can handle 2 OSD Planes and 2 Video Planes.
+
+ VPP: Video Post Processing
+ --------------------------
+
+ The Video Post Processing is in charge of the scaling and blending of the
+ various planes into a single pixel stream.
+ There is a special "pre-blending" used by the video planes with a dedicated
+ scaler and a "post-blending" to merge with the OSD Planes.
+ The OSD planes also have a dedicated scaler for one of the OSD.
+
+ VENC: Video Encoders
+ --------------------
+
+ The VENC is composed of the multiple pixel encoders
+ - ENCI : Interlace Video encoder for CVBS and Interlace HDMI
+ - ENCP : Progressive Video Encoder for HDMI
+ - ENCL : LCD LVDS Encoder
+ The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
+ tree and provides the scanout clock to the VPP and VIU.
+ The ENCI is connected to a single VDAC for Composite Output.
+ The ENCI and ENCP are connected to an on-chip HDMI Transceiver.

+Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
+
+The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
+See ../../mfd/atmel-hlcdc.txt for more details.
+
+Required properties:
+ - compatible: value should be "atmel,hlcdc-display-controller"
+ - pinctrl-names: the pin control state names. Should contain "default".
+ - pinctrl-0: should contain the default pinctrl states.
+ - #address-cells: should be set to 1.
+ - #size-cells: should be set to 0.
+
+Required children nodes:
+ Children nodes are encoding available output ports and their connections
+ to external devices using the OF graph representation (see ../graph.txt).
+ At least one port node is required.
+
+Optional properties in grandchild nodes:
+ Any endpoint grandchild node may specify a desired video interface
+ according to ../../media/video-interfaces.txt, specifically
+ - bus-width: recognized values are <12>, <16>, <18> and <24>, and
+ override any output mode selection heuristic, forcing "rgb444",
+ "rgb565", "rgb666" and "rgb888" respectively.
+
+Example:
+
+ hlcdc: hlcdc@f0030000 {
+ compatible = "atmel,sama5d3-hlcdc";
+ reg = <0xf0030000 0x2000>;
+ interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
+ clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
+ clock-names = "periph_clk","sys_clk", "slow_clk";
+
+ hlcdc-display-controller {
+ compatible = "atmel,hlcdc-display-controller";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ hlcdc_panel_output: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&panel_input>;
+ };

+ hlcdc_pwm: hlcdc-pwm {
+ compatible = "atmel,hlcdc-pwm";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_lcd_pwm>;
+ #pwm-cells = <3>;
+ };
+ };
+
+Example 2: With a video interface override to force rgb565; as above
+but with these changes/additions:
+
+ &hlcdc {
+ hlcdc-display-controller {
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb565>;
+
+ port@0 {
+ hlcdc_panel_output: endpoint@0 {
+ bus-width = <16>;
+ };
+ };

+
+description: |
+ The Freescale i.MX8qm/qxp LVDS Display Bridge(LDB) has two channels.
+
+ The i.MX8qm/qxp LDB is controlled by Control and Status Registers(CSR) module.
+ The CSR module, as a system controller, contains the LDB's configuration
+ registers.
+
+ For i.MX8qxp LDB, each channel supports up to 24bpp parallel input color
+ format and can map the input to VESA or JEIDA standards. The two channels
+ cannot be used simultaneously, that is to say, the user should pick one of
+ them to use. Two LDB channels from two LDB instances can work together in
+ LDB split mode to support a dual link LVDS display. The channel indexes
+ have to be different. Channel0 outputs odd pixels and channel1 outputs
+ even pixels.
+
+ For i.MX8qm LDB, each channel additionally supports up to 30bpp parallel
+ input color format. The two channels can be used simultaneously, either
+ in dual mode or split mode. In dual mode, the two channels output identical
+ data. In split mode, channel0 outputs odd pixels and channel1 outputs even
+ pixels.
+
+ A side note is that i.MX8qm/qxp LDB is officially called pixel mapper in
+ the SoC reference manuals. The pixel mapper uses logic of LDBs embedded in
+ i.MX6qdl/sx SoCs, i.e., it is essentially based on them. To keep the naming
+ consistency, this binding calls it LDB.

+description: |
+ ChromeOS EC ANX7688 is a display bridge that converts HDMI 2.0 to
+ DisplayPort 1.3 Ultra-HDi (4096x2160p60). It is an Analogix ANX7688 chip
+ which is connected to and operated by the ChromeOS Embedded Controller
+ (See google,cros-ec.yaml). It is accessed using I2C tunneling through
+ the EC and therefore its node should be a child of an EC I2C tunnel node
+ (See google,cros-ec-i2c-tunnel.yaml).

+description: |
+ The IT6505 is a high-performance DisplayPort 1.1a transmitter,
+ fully compliant with DisplayPort 1.1a, HDCP 1.3 specifications.
+ The IT6505 supports color depth of up to 36 bits (12 bits/color)
+ and ensures robust transmission of high-quality uncompressed video
+ content, along with uncompressed and compressed digital audio content.
+
+ Aside from the various video output formats supported, the IT6505
+ also encodes and transmits up to 8 channels of I2S digital audio,
+ with sampling rate up to 192kHz and sample size up to 24 bits.
+ In addition, an S/PDIF input port takes in compressed audio of up to
+ 192kHz frame rate.
+
+ Each IT6505 chip comes preprogrammed with an unique HDCP key,
+ in compliance with the HDCP 1.3 standard so as to provide secure
+ transmission of high-definition content. Users of the IT6505 need not
+ purchase any HDCP keys or ROMs.

+description: |
+ This binding supports transparent LVDS encoders and decoders that don't
+ require any configuration.
+
+ LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
+ incompatible data link layers have been used over time to transmit image data
+ to LVDS panels. This binding targets devices compatible with the following
+ specifications only.
+
+ [JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
+ 1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
+ [LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
+ Semiconductor
+ [VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
+ Electronics Standards Association (VESA)
+
+ Those devices have been marketed under the FPD-Link and FlatLink brand names
+ among others.

+Drivers for the second video output of the GE B850v3:
+ STDP4028-ge-b850v3-fw bridges (LVDS-DP)
+ STDP2690-ge-b850v3-fw bridges (DP-DP++)
+
+The video processing pipeline on the second output on the GE B850v3:
+
+ Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
+
+Each bridge has a dedicated flash containing firmware for supporting the custom
+design. The result is that, in this design, neither the STDP4028 nor the
+STDP2690 behave as the stock bridges would. The compatible strings include the
+suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with
+the firmware specific for the GE B850v3.
+
+The hardware do not provide control over the video processing pipeline, as the
+two bridges behaves as a single one. The only interfaces exposed by the
+hardware are EDID, HPD, and interrupts.
+

+description:
+ DisplayPort controllers provide a control channel to the sinks that

+ we can query properties about a sink and also configure it. In
+ particular, DP sinks support DDC over DP AUX which allows tunneling
+ a standard I2C DDC connection over the AUX channel.
+
+ To model this relationship, DP sinks should be placed as children
+ of the DP controller under the "aux-bus" node.
+
+ At the moment, this binding only handles the eDP case. It is
+ possible it will be extended in the future to handle the DP case.
+ For DP, presumably a connector would be listed under the DP AUX
+ bus instead of a panel.

+description: |
+ This document defines device tree properties common to DSI, Display
+ Serial Interface controllers and attached panels. It doesn't constitute
+ a device tree binding specification by itself but is meant to be referenced
+ by device tree bindings.
+
+ When referenced from panel device tree bindings the properties defined in
+ this document are defined as follows. The panel device tree bindings are
+ responsible for defining whether each property is required or optional.
+
+ Notice: this binding concerns DSI panels connected directly to a master
+ without any intermediate port graph to the panel. Each DSI master
+ can control one to four virtual channels to one panel. Each virtual
+ channel should have a node "panel" for their virtual channel with their
+ reg-property set to the virtual channel number, usually there is just
+ one virtual channel, number 0.
+
+properties:
+ $nodename:
+ pattern: "^dsi(@.*)?$"
+
+ clock-master:
+ type: boolean
+ description:
+ Should be enabled if the host is being used in conjunction with
+ another DSI host to drive the same peripheral. Hardware supporting
+ such a configuration generally requires the data on both the busses
+ to be driven by the same clock. Only the DSI host instance
+ controlling this clock should contain this property.

+ maximum: 3
+ description:
+ The virtual channel number of a DSI peripheral. Must be in the range
+ from 0 to 3, as DSI uses a 2-bit addressing scheme. Some DSI
+ peripherals respond to more than a single virtual channel. In that
+ case the reg property can take multiple entries, one for each virtual
+ channel that the peripheral responds to.
+
+ enforce-video-mode:
+ type: boolean
+ description:
+ The best option is usually to run a panel in command mode, as this
+ gives better control over the panel hardware. However for different
+ reasons like broken hardware, missing features or testing, it may be

+Device-Tree bindings for LVDS Display Bridge (ldb)
+
+LVDS Display Bridge
+===================
+
+The LVDS Display Bridge device tree node contains up to two lvds-channel
+nodes describing each of the two LVDS encoder channels of the bridge.
+
+Required properties:
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+ - compatible : should be "fsl,imx53-ldb" or "fsl,imx6q-ldb".
+ Both LDB versions are similar, but i.MX6 has an additional
+ multiplexer in the front to select any of the four IPU display
+ interfaces as input for each LVDS channel.
+ - gpr : should be <&gpr> on i.MX53 and i.MX6q.
+ The phandle points to the iomuxc-gpr region containing the LVDS
+ control register.
+- clocks, clock-names : phandles to the LDB divider and selector clocks and to
+ the display interface selector clocks, as described in
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ The following clocks are expected on i.MX53:
+ "di0_pll" - LDB LVDS channel 0 mux
+ "di1_pll" - LDB LVDS channel 1 mux
+ "di0" - LDB LVDS channel 0 gate
+ "di1" - LDB LVDS channel 1 gate
+ "di0_sel" - IPU1 DI0 mux
+ "di1_sel" - IPU1 DI1 mux
+ On i.MX6q the following additional clocks are needed:
+ "di2_sel" - IPU2 DI0 mux
+ "di3_sel" - IPU2 DI1 mux
+ The needed clock numbers for each are documented in
+ Documentation/devicetree/bindings/clock/imx5-clock.yaml, and in
+ Documentation/devicetree/bindings/clock/imx6q-clock.yaml.
+
+Optional properties:
+ - pinctrl-names : should be "default" on i.MX53, not used on i.MX6q
+ - pinctrl-0 : a phandle pointing to LVDS pin settings on i.MX53,
+ not used on i.MX6q
+ - fsl,dual-channel : boolean. if it exists, only LVDS channel 0 should
+ be configured - one input will be distributed on both outputs in dual
+ channel mode
+
+LVDS Channel
+============
+
+Each LVDS Channel has to contain either an of graph link to a panel device node
+or a display-timings node that describes the video timings for the connected
+LVDS display as well as the fsl,data-mapping and fsl,data-width properties.
+
+Required properties:
+ - reg : should be <0> or <1>
+ - port: Input and output port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/graph.txt.
+ On i.MX5, the internal two-input-multiplexer is used. Due to hardware
+ limitations, only one input port (port@[0,1]) can be used for each channel
+ (lvds-channel@[0,1], respectively).
+ On i.MX6, there should be four input ports (port@[0-3]) that correspond
+ to the four LVDS multiplexer inputs.
+ A single output port (port@2 on i.MX5, port@4 on i.MX6) must be connected
+ to a panel input port. Optionally, the output port can be left out if
+ display-timings are used instead.
+
+Optional properties (required if display-timings are used):
+ - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+ - display-timings : A node that describes the display timings as defined in
+ Documentation/devicetree/bindings/display/panel/display-timing.txt.
+ - fsl,data-mapping : should be "spwg" or "jeida"
+ This describes how the color bits are laid out in the
+ serialized LVDS signal.
+ - fsl,data-width : should be <18> or <24>
+
+example:
+
+gpr: iomuxc-gpr@53fa8000 {
+ /* ... */
+};
+
+ldb: ldb@53fa8008 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx53-ldb";
+ gpr = <&gpr>;
+ clocks = <&clks IMX5_CLK_LDB_DI0_SEL>,
+ <&clks IMX5_CLK_LDB_DI1_SEL>,
+ <&clks IMX5_CLK_IPU_DI0_SEL>,
+ <&clks IMX5_CLK_IPU_DI1_SEL>,
+ <&clks IMX5_CLK_LDB_DI0_GATE>,
+ <&clks IMX5_CLK_LDB_DI1_GATE>;
+ clock-names = "di0_pll", "di1_pll",
+ "di0_sel", "di1_sel",
+ "di0", "di1";
+
+ /* Using an of-graph endpoint link to connect the panel */
+ lvds-channel@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ lvds0_in: endpoint {
+ remote-endpoint = <&ipu_di0_lvds0>;
+ };
+ };
+
+ port@2 {
+ reg = <2>;
+
+ lvds0_out: endpoint {
+ remote-endpoint = <&panel_in>;
+ };
+ };
+ };
+
+ /* Using display-timings and fsl,data-mapping/width instead */
+ lvds-channel@1 {
+ #address-cells = <1>;

+ Semiconductor
+ [VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
+ Electronics Standards Association (VESA)
+
+ Device compatible with those specifications have been marketed under the
+ FPD-Link and FlatLink brands.

+PXA LCD Controller
+------------------
+
+Required properties:
+ - compatible : one of these
+ "marvell,pxa2xx-lcdc",
+ "marvell,pxa270-lcdc",
+ "marvell,pxa300-lcdc"
+ - reg : should contain 1 register range (address and length).
+ - interrupts : framebuffer controller interrupt.
+ - clocks: phandle to input clocks
+
+Optional properties:
+ - lcd-supply: A phandle to a power regulator that controls the LCD voltage.
+
+Required nodes:
+ - port: connection to the LCD panel (see video-interfaces.txt)
+ This node must have its properties bus-width and remote-endpoint set.
+ If the panel is not a TFT color panel, then a "lcd-type" property in
+ the panel should specify the panel type.
+ This panel node should be in the board dts.
+
+Example:
+ lcd-controller@40500000 {
+ compatible = "marvell,pxa2xx-lcdc";
+ reg = <0x44000000 0x10000>;
+ interrupts = <17>;

+description:
+ ETHDR (ET High Dynamic Range) is a MediaTek internal HDR engine and is
+ designed for HDR video and graphics conversion in the external display path.
+ It handles multiple HDR input types and performs tone mapping, color
+ space/color format conversion, and then combine different layers,
+ output the required HDR or SDR signal to the subsequent display path.
+ This engine is composed of two video frontends, two graphic frontends,
+ one video backend and a mixer. ETHDR has two DMA function blocks, DS and ADL.
+ These two function blocks read the pre-programmed registers from DRAM and
+ set them to HW in the v-blanking period.

+MIPI DSI (Display Serial Interface) busses
+==========================================
+
+The MIPI Display Serial Interface specifies a serial bus and a protocol for
+communication between a host and up to four peripherals. This document will
+define the syntax used to represent a DSI bus in a device tree.
+
+This document describes DSI bus-specific properties only or defines existing
+standard properties in the context of the DSI bus.
+
+Each DSI host provides a DSI bus. The DSI host controller's node contains a
+set of properties that characterize the bus. Child nodes describe individual
+peripherals on that bus.
+
+The following assumes that only a single peripheral is connected to a DSI
+host. Experience shows that this is true for the large majority of setups.
+
+DSI host
+========
+
+In addition to the standard properties and those defined by the parent bus of
+a DSI host, the following properties apply to a node representing a DSI host.
+
+Required properties:
+- #address-cells: The number of cells required to represent an address on the
+ bus. DSI peripherals are addressed using a 2-bit virtual channel number, so
+ a maximum of 4 devices can be addressed on a single bus. Hence the value of
+ this property should be 1.
+- #size-cells: Should be 0. There are cases where it makes sense to use a
+ different value here. See below.
+
+Optional properties:
+- clock-master: boolean. Should be enabled if the host is being used in
+ conjunction with another DSI host to drive the same peripheral. Hardware
+ supporting such a configuration generally requires the data on both the busses
+ to be driven by the same clock. Only the DSI host instance controlling this
+ clock should contain this property.
+
+DSI peripheral
+==============
+
+Peripherals with DSI as control bus, or no control bus
+------------------------------------------------------
+
+Peripherals with the DSI bus as the primary control bus, or peripherals with
+no control bus but use the DSI bus to transmit pixel data are represented
+as child nodes of the DSI host's node. Properties described here apply to all
+DSI peripherals, but individual bindings may want to define additional,
+device-specific properties.
+
+Required properties:
+- reg: The virtual channel number of a DSI peripheral. Must be in the range
+ from 0 to 3.
+
+Some DSI peripherals respond to more than a single virtual channel. In that
+case two alternative representations can be chosen:
+- The reg property can take multiple entries, one for each virtual channel
+ that the peripheral responds to.
+- If the virtual channels that a peripheral responds to are consecutive, the
+ #size-cells can be set to 1. The first cell of each entry in the reg
+ property is the number of the first virtual channel and the second cell is
+ the number of consecutive virtual channels.
+
+Peripherals with a different control bus
+----------------------------------------
+
+There are peripherals that have I2C/SPI (or some other non-DSI bus) as the
+primary control bus, but are also connected to a DSI bus (mostly for the data
+path). Connections between such peripherals and a DSI host can be represented
+using the graph bindings [1], [2].
+
+Peripherals that support dual channel DSI
+-----------------------------------------
+
+Peripherals with higher bandwidth requirements can be connected to 2 DSI
+busses. Each DSI bus/channel drives some portion of the pixel data (generally
+left/right half of each line of the display, or even/odd lines of the display).
+The graph bindings should be used to represent the multiple DSI busses that are
+connected to this peripheral. Each DSI host's output endpoint can be linked to
+an input endpoint of the DSI peripheral.
+
+[1] Documentation/devicetree/bindings/graph.txt
+[2] Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Examples
+========
+- (1), (2) and (3) are examples of a DSI host and peripheral on the DSI bus
+ with different virtual channel configurations.
+- (4) is an example of a peripheral on a I2C control bus connected to a
+ DSI host using of-graph bindings.
+- (5) is an example of 2 DSI hosts driving a dual-channel DSI peripheral,
+ which uses I2C as its primary control bus.

+Multi-Inno MI0283QT display panel
+
+Required properties:
+- compatible: "multi-inno,mi0283qt".
+
+The node for this driver must be a child node of a SPI controller, hence
+all mandatory properties described in ../spi/spi-bus.txt must be specified.
+
+Optional properties:
+- dc-gpios: D/C pin. The presence/absence of this GPIO determines
+ the panel interface mode (IM[3:0] pins):
+ - present: IM=x110 4-wire 8-bit data serial interface
+ - absent: IM=x101 3-wire 9-bit data serial interface
+- reset-gpios: Reset pin
+- power-supply: A regulator node for the supply voltage.
+- backlight: phandle of the backlight device attached to the panel
+- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
+
+Example:
+ mi0283qt@0{
+ compatible = "multi-inno,mi0283qt";
+ reg = <0>;
+ spi-max-frequency = <32000000>;
+ rotation = <90>;

+description: |
+ The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
+ A dual-LVDS interface is a dual-link connection with even pixels traveling
+ on one link, and with odd pixels traveling on the other link.
+
+ The panel expects odd pixels on the first port, and even pixels on the
+ second port, therefore the ports must be marked accordingly (with either
+ dual-lvds-odd-pixels or dual-lvds-even-pixels).

+description: |
+ This document defines device tree properties common to several classes of
+ display panels. It doesn't constitute a device tree binding specification by
+ itself but is meant to be referenced by device tree bindings.
+
+ When referenced from panel device tree bindings the properties defined in this
+ document are defined as follows. The panel device tree bindings are
+ responsible for defining whether each property is required or optional.
+
+properties:
+ # Descriptive Properties
+ width-mm:
+ description:
+ Specifies the width of the physical area where images are displayed. This
+ property is expressed in millimeters and rounded to the closest unit.
+
+ height-mm:
+ description:
+ Specifies the height of the physical area where images are displayed. This
+ property is expressed in millimeters and rounded to the closest unit.
+
+ label:
+ description: |
+ The label property specifies a symbolic name for the panel as a
+ string suitable for use by humans. It typically contains a name inscribed
+ on the system (e.g. as an affixed label) or specified in the system's
+ documentation (e.g. in the user's manual).
+
+ If no such name exists, and unless the property is mandatory according to
+ device tree bindings, it shall rather be omitted than constructed of
+ non-descriptive information. For instance an LCD panel in a system that
+ contains a single panel shall not be labelled "LCD" if that name is not
+ inscribed on the system or used in a descriptive fashion in system
+ documentation.
+
+ rotation:
+ description:
+ Display rotation in degrees counter clockwise (0,90,180,270)
+ $ref: /schemas/types.yaml#/definitions/uint32
+ enum: [0, 90, 180, 270]
+
+ # Display Timings
+ panel-timing:
+ description:
+ Most display panels are restricted to a single resolution and
+ require specific display timings. The panel-timing subnode expresses those
+ timings.
+ $ref: panel-timing.yaml#
+
+ display-timings:
+ description:
+ Some display panels support several resolutions with different timings.
+ The display-timings bindings supports specifying several timings and
+ optionally specifying which is the native mode.
+ $ref: display-timings.yaml#
+
+ # Connectivity
+ port:
+ $ref: /schemas/graph.yaml#/properties/port
+
+ ddc-i2c-bus:
+ $ref: /schemas/types.yaml#/definitions/phandle
+ description:
+ Some panels expose EDID information through an I2C-compatible
+ bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
+ phandle to the system I2C controller connected to that bus.
+
+ no-hpd:
+ type: boolean
+ description:
+ This panel is supposed to communicate that it's ready via HPD
+ (hot plug detect) signal, but the signal isn't hooked up so we should
+ hardcode the max delay from the panel spec when powering up the panel.
+
+ hpd-gpios:
+ maxItems: 1
+ description:
+ If Hot Plug Detect (HPD) is connected to a GPIO in the system rather
+ than a dedicated HPD pin the pin can be specified here.
+
+ # Control I/Os
+
+ # Many display panels can be controlled through pins driven by GPIOs. The nature
+ # and timing of those control signals are device-specific and left for panel
+ # device tree bindings to specify. The following GPIO specifiers can however be
+ # used for panels that implement compatible control signals.
+
+ enable-gpios:
+ maxItems: 1
+ description: |
+ Specifier for a GPIO connected to the panel enable control signal. The
+ enable signal is active high and enables operation of the panel. This
+ property can also be used for panels implementing an active low power down
+ signal, which is a negated version of the enable signal. Active low enable
+ signals (or active high power down signals) can be supported by inverting
+ the GPIO specifier polarity flag.
+
+ Note that the enable signal control panel operation only and must not be
+ confused with a backlight enable signal.
+
+ reset-gpios:
+ maxItems: 1
+ description:
+ Specifier for a GPIO connected to the panel reset control signal.
+ The reset signal is active low and resets the panel internal logic
+ while active. Active high reset signals can be supported by inverting the
+ GPIO specifier polarity flag.
+
+ te-gpios:
+ maxItems: 1
+ description:
+ GPIO spec for the tearing effect synchronization signal.
+ The tearing effect signal is active high. Active low signals can be
+ supported by inverting the GPIO specifier polarity flag.
+
+ # Power
+ power-supply:
+ description:
+ Display panels require power to be supplied. While several panels need
+ more than one power supply with panel-specific constraints governing the
+ order and timings of the power supplies, in many cases a single power
+ supply is sufficient, either because the panel has a single power rail, or
+ because all its power rails can be driven by the same supply. In that case
+ the power-supply property specifies the supply powering the panel as a
+ phandle to a regulator.
+
+ # Backlight
+
+ # Most display panels include a backlight. Some of them also include a backlight
+ # controller exposed through a control bus such as I2C or DSI. Others expose
+ # backlight control through GPIO, PWM or other signals connected to an external
+ # backlight controller.
+
+ backlight:
+ $ref: /schemas/types.yaml#/definitions/phandle
+ description:
+ For panels whose backlight is controlled by an external backlight
+ controller, this property contains a phandle that references the
+ controller.

+title: Probeable (via DP AUX / EDID) eDP Panels with simple poweron sequences
+
+maintainers:
+ - Douglas Anderson <dianders@chromium.org>
+
+description: |
+ This binding file can be used to indicate that an eDP panel is connected
+ to a Embedded DisplayPort AUX bus (see display/dp-aux-bus.yaml) without
+ actually specifying exactly what panel is connected. This is useful for
+ the case that more than one different panel could be connected to the
+ board, either for second-sourcing purposes or to support multiple SKUs
+ with different LCDs that hook up to a common board.
+
+ As per above, a requirement for using this binding is that the panel is
+ represented under the DP AUX bus. This means that we can use any
+ information provided by the DP AUX bus (including the EDID) to identify
+ the panel. We can use this to identify display size, resolution, and
+ timings among other things.
+
+ One piece of information about eDP panels that is typically _not_
+ provided anywhere on the DP AUX bus is the power sequencing timings.
+ This is the reason why, historically, we've always had to explicitly
+ list eDP panels. We solve that here with two tricks. The "worst case"
+ power on timings for any panels expected to be connected to a board are
+ specified in these bindings. Once we've powered on, it's expected that
+ the operating system will lookup the panel in a table (based on EDID
+ information) to figure out other power sequencing timings.
+
+ eDP panels in general can have somewhat arbitrary power sequencing
+ requirements. However, even though it's arbitrary in general, the
+ vast majority of panel datasheets have a power sequence diagram that
+ looks the exactly the same as every other panel. Each panel datasheet
+ cares about different timings in this diagram but the fact that the
+ diagram is so similar means we can come up with a single driver to
+ handle it.
+
+ These diagrams all look roughly like this, sometimes labeled with
+ slightly different numbers / lines but all pretty much the same
+ sequence. This is because much of this diagram comes straight from
+ the eDP Standard.

+description: |
+ This binding is for display panels using a MIPI DBI compatible controller
+ in SPI mode.
+
+ The MIPI Alliance Standard for Display Bus Interface defines the electrical
+ and logical interfaces for display controllers historically used in mobile
+ phones. The standard defines 4 display architecture types and this binding is
+ for type 1 which has full frame memory. There are 3 interface types in the
+ standard and type C is the serial interface.
+
+ The standard defines the following interface signals for type C:
+ - Power:
+ - Vdd: Power supply for display module
+ Called power-supply in this binding.
+ - Vddi: Logic level supply for interface signals
+ Called io-supply in this binding.
+ - Interface:
+ - CSx: Chip select
+ - SCL: Serial clock
+ - Dout: Serial out
+ - Din: Serial in
+ - SDA: Bidrectional in/out
+ - D/CX: Data/command selection, high=data, low=command
+ Called dc-gpios in this binding.
+ - RESX: Reset when low
+ Called reset-gpios in this binding.
+
+ The type C interface has 3 options:
+
+ - Option 1: 9-bit mode and D/CX as the 9th bit
+ | Command | the next command or following data |
+ |<0><D7><D6><D5><D4><D3><D2><D1><D0>|<D/CX><D7><D6><D5><D4><D3><D2><D1><D0>|
+
+ - Option 2: 16-bit mode and D/CX as a 9th bit
+ | Command or data |
+ |<X><X><X><X><X><X><X><D/CX><D7><D6><D5><D4><D3><D2><D1><D0>|
+
+ - Option 3: 8-bit mode and D/CX as a separate interface line
+ | Command or data |
+ |<D7><D6><D5><D4><D3><D2><D1><D0>|
+
+ The panel resolution is specified using the panel-timing node properties
+ hactive (width) and vactive (height). The other mandatory panel-timing
+ properties should be set to zero except clock-frequency which can be
+ optionally set to inform about the actual pixel clock frequency.
+
+ If the panel is wired to the controller at an offset specify this using
+ hback-porch (x-offset) and vback-porch (y-offset).

+ This binding file is a collection of the DSI panels that
+ requires only a single power-supply.
+ There are optionally a backlight and an enable GPIO.
+ The panel may use an OF graph binding for the association to the display,
+ or it may be a direct child node of the display.
+
+ If the panel is more advanced a dedicated binding file is required.

+description: |
+ This panel requires a dual-channel DSI host to operate. It supports two modes:
+ - left-right: each channel drives the left or right half of the screen
+ - even-odd: each channel drives the even or odd lines of the screen
+
+ Each of the DSI channels controls a separate DSI peripheral. The peripheral
+ driven by the first link (DSI-LINK1), left or even, is considered the primary
+ peripheral and controls the device. The 'link2' property contains a phandle
+ to the peripheral driven by the second link (DSI-LINK2, right or odd).
+
+ Note that in video mode the DSI-LINK1 interface always provides the left/even
+ pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
+ is possible to program either link to drive the left/even or right/odd pixels
+ but for the sake of consistency this binding assumes that the same assignment
+ is chosen as for video mode.

+description: |+
+ This panel driver is a component that acts as an intermediary
+ between an RGB output and a variety of panels. The panel
+ driver is strapped up in electronics to the desired resolution
+ and other properties, and has a control interface over 3WIRE
+ SPI. By talking to the TPG110 over SPI, the strapped properties
+ can be discovered and the hardware is therefore mostly
+ self-describing.
+
+ +--------+
+ SPI -> | TPO | -> physical display
+ RGB -> | TPG110 |
+ +--------+
+
+ If some electrical strap or alternate resolution is desired,
+ this can be set up by taking software control of the display
+ over the SPI interface. The interface can also adjust
+ for properties of the display such as gamma correction and
+ certain electrical driving levels.
+
+ The TPG110 does not know the physical dimensions of the panel
+ connected, so this needs to be specified in the device tree.
+
+ It requires a GPIO line for control of its reset line.
+
+ The serial protocol has line names that resemble I2C but the
+ protocol is not I2C but 3WIRE SPI.

+
+description: |+
+ A simple frame-buffer describes a frame-buffer setup by firmware or
+ the bootloader, with the assumption that the display hardware has
+ already been set up to scan out from the memory pointed to by the
+ reg property.
+
+ Since simplefb nodes represent runtime information they must be
+ sub-nodes of the chosen node (*). Simplefb nodes must be named
+ framebuffer@<address>.
+
+ If the devicetree contains nodes for the display hardware used by a
+ simplefb, then the simplefb node must contain a property called
+ display, which contains a phandle pointing to the primary display
+ hw node, so that the OS knows which simplefb to disable when handing
+ over control to a driver for the real hardware. The bindings for the
+ hw nodes must specify which node is considered the primary node.
+
+ If a panel node is given, then the driver uses this to configure the
+ physical width and height of the display. If no panel node is given,
+ then the driver uses the width and height properties of the simplefb
+ node to estimate it.
+
+ It is advised to add display# aliases to help the OS determine how
+ to number things. If display# aliases are used, then if the simplefb
+ node contains a display property then the /aliases/display# path
+ must point to the display hw node the display property points to,
+ otherwise it must point directly to the simplefb node.
+
+ If a simplefb node represents the preferred console for user
+ interaction, then the chosen node stdout-path property should point
+ to it, or to the primary display hw node, as with display#
+ aliases. If display aliases are used then it should be set to the
+ alias instead.
+
+ It is advised that devicetree files contain pre-filled, disabled
+ framebuffer nodes, so that the firmware only needs to update the
+ mode information and enable them. This way if e.g. later on support
+ for more display clocks get added, the simplefb nodes will already
+ contain this info and the firmware does not need to be updated.
+
+ If pre-filled framebuffer nodes are used, the firmware may need
+ extra information to find the right node. In that case an extra
+ platform specific compatible and platform specific properties should
+ be used and documented.

+
+description: |
+ The Unisoc DRM master device is a virtual device needed to list all
+ DPU devices or other display interface nodes that comprise the
+ graphics subsystem.
+
+ Unisoc's display pipeline have several components as below description,
+ multi display controllers and corresponding physical interfaces.
+ For different display scenarios, dpu0 and dpu1 maybe binding to different
+ encoder.
+
+ E.g:
+ dpu0 and dpu1 both binding to DSI for dual mipi-dsi display;
+ dpu0 binding to DSI for primary display, and dpu1 binding to DP for external display;

+Texas Instruments OMAP Display Subsystem
+========================================
+
+Generic Description
+-------------------
+
+This document is a generic description of the OMAP Display Subsystem bindings.
+Binding details for each OMAP SoC version are described in respective binding
+documentation.
+
+The OMAP Display Subsystem (DSS) hardware consists of DSS Core, DISPC module and
+a number of encoder modules. All DSS versions contain DSS Core and DISPC, but
+the encoder modules vary.
+
+The DSS Core is the parent of the other DSS modules, and manages clock routing,
+integration to the SoC, etc.
+
+DISPC is the display controller, which reads pixels from the memory and outputs
+a RGB pixel stream to encoders.
+
+The encoder modules encode the received RGB pixel stream to a video output like
+HDMI, MIPI DPI, etc.
+
+Video Ports
+-----------
+
+The DSS Core and the encoders have video port outputs. The structure of the
+video ports is described in Documentation/devicetree/bindings/graph.txt,
+and the properties for the ports and endpoints for each encoder are
+described in the SoC's DSS binding documentation.
+
+The video ports are used to describe the connections to external hardware, like
+panels or external encoders.
+
+Aliases
+-------
+
+The board dts file may define aliases for displays to assign "displayX" style
+name for each display. If no aliases are defined, a semi-random number is used
+for the display.
+
+Example
+-------
+
+A shortened example of the DSS description for OMAP4, with non-relevant parts
+removed, defined in omap4.dtsi:
+
+dss: dss@58000000 {

+ #size-cells = <1>;
+ ranges;
+

+ compatible = "ti,omap4-dispc";
+ reg = <0x58001000 0x1000>;
+ interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "dss_dispc";

+The Panda board has a DVI and a HDMI connector, and the board contains a TFP410
+chip (MIPI DPI to DVI encoder) and a TPD12S015 chip (HDMI ESD protection & level
+shifter). The video pipelines for the connectors are formed as follows:

+Device-Tree bindings for tilcdc DRM driver
+
+Required properties:

+ - "ti,da850-tilcdc" for DA850/AM18x/OMAP-L138 based boards
+ - interrupts: the interrupt number
+ - reg: base address and size of the LCDC device
+

+
+Optional properties:
+ - max-bandwidth: The maximum pixels per second that the memory
+ interface / lcd controller combination can sustain
+ - max-width: The maximum horizontal pixel width supported by
+ the lcd controller.
+ - max-pixelclock: The maximum pixel clock that can be supported
+ by the lcd controller in KHz.
+ - blue-and-red-wiring: Recognized values "straight" or "crossed".
+ This property deals with the LCDC revision 2 (found on AM335x)
+ color errata [1].
+ - "straight" indicates normal wiring that supports RGB565,
+ BGR888, and XBGR8888 color formats.
+ - "crossed" indicates wiring that has blue and red wires
+ crossed. This setup supports BGR565, RGB888 and XRGB8888
+ formats.
+ - If the property is not present or its value is not recognized
+ the legacy mode is assumed. This configuration supports RGB565,
+ RGB888 and XRGB8888 formats. However, depending on wiring, the red
+ and blue colors are swapped in either 16 or 24-bit color modes.
+
+Optional nodes:
+
+ - port/ports: to describe a connection to an external encoder. The
+ binding follows Documentation/devicetree/bindings/graph.txt and
+ supports a single port with a single endpoint.
+
+ - See also Documentation/devicetree/bindings/display/tilcdc/panel.txt and
+ Documentation/devicetree/bindings/display/bridge/ti,tfp410.yaml for connecting
+ tfp410 DVI encoder or lcd panel to lcdc
+
+[1] There is an errata about AM335x color wiring. For 16-bit color mode
+ the wires work as they should (LCD_DATA[0:4] is for Blue[3:7]),
+ but for 24 bit color modes the wiring of blue and red components is
+ crossed and LCD_DATA[0:4] is for Red[3:7] and LCD_DATA[11:15] is

+title: Xilinx ZynqMP DisplayPort Subsystem
+
+description: |
+ The DisplayPort subsystem of Xilinx ZynqMP (Zynq UltraScale+ MPSoC)
+ implements the display and audio pipelines based on the DisplayPort v1.2
+ standard. The subsystem includes multiple functional blocks as below:
+
+ +------------------------------------------------------------+
+ +--------+ | +----------------+ +-----------+ |
+ | DPDMA | --->| | --> | Video | Video +-------------+ |
+ | 4x vid | | | | | Rendering | -+--> | | | +------+
+ | 2x aud | | | Audio/Video | --> | Pipeline | | | DisplayPort |---> | PHY0 |
+ +--------+ | | Buffer Manager | +-----------+ | | Source | | +------+
+ | | and STC | +-----------+ | | Controller | | +------+
+ Live Video --->| | --> | Audio | Audio | |---> | PHY1 |
+ | | | | Mixer | --+-> | | | +------+
+ Live Audio --->| | --> | | || +-------------+ |
+ | +----------------+ +-----------+ || |
+ +---------------------------------------||-------------------+
+ vv
+ Blended Video and
+ Mixed Audio to PL
+
+ The Buffer Manager interacts with external interface such as DMA engines or
+ live audio/video streams from the programmable logic. The Video Rendering
+ Pipeline blends the video and graphics layers and performs colorspace
+ conversion. The Audio Mixer mixes the incoming audio streams. The DisplayPort
+ Source Controller handles the DisplayPort protocol and connects to external
+ PHYs.
+
+ The subsystem supports 2 video and 2 audio streams, and various pixel formats
+ and depths up to 4K@30 resolution.

+
+description: |
+ The Xylon LogiCVC is a display controller that supports multiple layers.
+ It is usually implemented as programmable logic and was optimized for use
+ with Xilinx Zynq-7000 SoCs and Xilinx FPGAs.
+
+ Because the controller is intended for use in a FPGA, most of the
+ configuration of the controller takes place at logic configuration bitstream
+ synthesis time. As a result, many of the device-tree bindings are meant to
+ reflect the synthesis configuration and must not be configured differently.
+ Matching synthesis parameters are provided when applicable.
+
+ Layers are declared in the "layers" sub-node and have dedicated configuration.
+ In version 3 of the controller, each layer has fixed memory offset and address
+ starting from the video memory base address for its framebuffer. In version 4,
+ framebuffers are configured with a direct memory address instead.

+ - reg: Specification for the controllers memory mapped register map.
+ - interrupts: Specification for the controllers interrupt.
+ - clocks: Phandle and specifier to the controllers AXI interface clock
+ - #dma-cells: Must be 1.
+
+Required sub-nodes:
+ - adi,channels: This sub-node must contain a sub-node for each DMA channel. For
+ the channel sub-nodes the following bindings apply. They must match the
+ configuration options of the peripheral as it was instantiated.
+
+Required properties for adi,channels sub-node:
+ - #size-cells: Must be 0
+ - #address-cells: Must be 1
+
+Required channel sub-node properties:
+ - reg: Which channel this node refers to.
+ - adi,source-bus-width,
+ adi,destination-bus-width: Width of the source or destination bus in bits.
+ - adi,source-bus-type,
+ adi,destination-bus-type: Type of the source or destination bus. Must be one
+ of the following:
+ 0 (AXI_DMAC_TYPE_AXI_MM): Memory mapped AXI interface
+ 1 (AXI_DMAC_TYPE_AXI_STREAM): Streaming AXI interface
+ 2 (AXI_DMAC_TYPE_AXI_FIFO): FIFO interface
+
+Deprecated optional channel properties:
+ - adi,length-width: Width of the DMA transfer length register.
+ - adi,cyclic: Must be set if the channel supports hardware cyclic DMA
+ transfers.
+ - adi,2d: Must be set if the channel supports hardware 2D DMA transfers.
+
+DMA clients connected to the AXI-DMAC DMA controller must use the format
+described in the dma.txt file using a one-cell specifier. The value of the
+specifier refers to the DMA channel index.
+
+Example:

+Applied Micro X-Gene SoC DMA nodes
+
+DMA nodes are defined to describe on-chip DMA interfaces in
+APM X-Gene SoC.
+
+Required properties for DMA interfaces:
+- compatible: Should be "apm,xgene-dma".
+- device_type: set to "dma".
+- reg: Address and length of the register set for the device.
+ It contains the information of registers in the following order:
+ 1st - DMA control and status register address space.
+ 2nd - Descriptor ring control and status register address space.
+ 3rd - Descriptor ring command register address space.
+ 4th - Soc efuse register address space.
+- interrupts: DMA has 5 interrupts sources. 1st interrupt is
+ DMA error reporting interrupt. 2nd, 3rd, 4th and 5th interrupts
+ are completion interrupts for each DMA channels.
+- clocks: Reference to the clock entry.
+
+Optional properties:
+- dma-coherent : Present if dma operations are coherent
+
+Example:
+ dmaclk: dmaclk@1f27c000 {
+ compatible = "apm,xgene-device-clock";
+ #clock-cells = <1>;

+ Apple's Audio DMA Controller (ADMAC) is used to fetch and store audio samples
+ on SoCs from the "Apple Silicon" family.
+
+ The controller has been seen with up to 24 channels. Even-numbered channels
+ are TX-only, odd-numbered are RX-only. Individual channels are coupled to

+DMA clients connected to the Atmel DMA controller must use the format

+a phandle plus two integer cells.
+The three cells in order are:
+
+1. A phandle pointing to the DMA controller.
+2. The memory interface (16 most significant bits), the peripheral interface
+(16 less significant bits).
+3. Parameters for the at91 DMA configuration register which are device
+dependent:
+ - bit 7-0: peripheral identifier for the hardware handshaking interface. The
+ identifier can be different for tx and rx.
+ - bit 11-8: FIFO configuration. 0 for half FIFO, 1 for ALAP, 2 for ASAP.

+
+* DMA controller
+
+Required properties:
+- compatible : Should be "fsl,<chip>-dma". chip can be imx1, imx21 or imx27
+- reg : Should contain DMA registers location and length
+- interrupts : First item should be DMA interrupt, second one is optional and
+ should contain DMA Error interrupt
+- #dma-cells : Has to be 1. imx-dma does not support anything else.
+
+Optional properties:
+- dma-channels : Number of DMA channels supported. Should be 16.
+- #dma-channels : deprecated
+- dma-requests : Number of DMA requests supported.
+- #dma-requests : deprecated
+
+Example:
+
+ dma: dma@10001000 {
+ compatible = "fsl,imx27-dma";
+ reg = <0x10001000 0x1000>;
+ interrupts = <32 33>;
+ #dma-cells = <1>;
+ dma-channels = <16>;
+ };
+
+
+* DMA client
+
+Clients have to specify the DMA requests with phandles in a list.
+
+Required properties:
+- dmas: List of one or more DMA request specifiers. One DMA request specifier
+ consists of a phandle to the DMA controller followed by the integer
+ specifying the request line.
+- dma-names: List of string identifiers for the DMA requests. For the correct
+ names, have a look at the specific client driver.
+
+Example:
+
+ sdhci1: sdhci@10013000 {
+ ...
+ dmas = <&dma 7>;
+ dma-names = "rx-tx";
+ ...
+ };

+* IMG Multi-threaded DMA Controller (MDC)
+
+Required properties:
+- compatible: Must be "img,pistachio-mdc-dma".
+- reg: Must contain the base address and length of the MDC registers.
+- interrupts: Must contain all the per-channel DMA interrupts.
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clock/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - sys: MDC system interface clock.
+- img,cr-periph: Must contain a phandle to the peripheral control syscon
+ node which contains the DMA request to channel mapping registers.
+- img,max-burst-multiplier: Must be the maximum supported burst size multiplier.
+ The maximum burst size is this value multiplied by the hardware-reported bus
+ width.
+- #dma-cells: Must be 3:
+ - The first cell is the peripheral's DMA request line.
+ - The second cell is a bitmap specifying to which channels the DMA request
+ line may be mapped (i.e. bit N set indicates channel N is usable).
+ - The third cell is the thread ID to be used by the channel.
+
+Optional properties:
+- dma-channels: Number of supported DMA channels, up to 32. If not specified
+ the number reported by the hardware is used.
+
+Example:
+

+Qualcomm Technologies HIDMA Management interface
+
+Qualcomm Technologies HIDMA is a high speed DMA device. It only supports
+memcpy and memset capabilities. It has been designed for virtualized
+environments.
+
+Each HIDMA HW instance consists of multiple DMA channels. These channels
+share the same bandwidth. The bandwidth utilization can be partitioned
+among channels based on the priority and weight assignments.
+
+There are only two priority levels and 15 weigh assignments possible.
+
+Other parameters here determine how much of the system bus this HIDMA
+instance can use like maximum read/write request and number of bytes to
+read/write in a single burst.
+
+Main node required properties:
+- compatible: "qcom,hidma-mgmt-1.0";
+- reg: Address range for DMA device
+- dma-channels: Number of channels supported by this DMA controller.
+- max-write-burst-bytes: Maximum write burst in bytes that HIDMA can
+ occupy the bus for in a single transaction. A memcpy requested is
+ fragmented to multiples of this amount. This parameter is used while
+ writing into destination memory. Setting this value incorrectly can
+ starve other peripherals in the system.
+- max-read-burst-bytes: Maximum read burst in bytes that HIDMA can
+ occupy the bus for in a single transaction. A memcpy request is
+ fragmented to multiples of this amount. This parameter is used while
+ reading the source memory. Setting this value incorrectly can starve
+ other peripherals in the system.
+- max-write-transactions: This value is how many times a write burst is
+ applied back to back while writing to the destination before yielding
+ the bus.
+- max-read-transactions: This value is how many times a read burst is
+ applied back to back while reading the source before yielding the bus.
+- channel-reset-timeout-cycles: Channel reset timeout in cycles for this SOC.
+ Once a reset is applied to the HW, HW starts a timer for reset operation
+ to confirm. If reset is not completed within this time, HW reports reset
+ failure.
+
+Sub-nodes:
+
+HIDMA has one or more DMA channels that are used to move data from one
+memory location to another.
+
+When the OS is not in control of the management interface (i.e. it's a guest),
+the channel nodes appear on their own, not under a management node.
+
+Required properties:
+- compatible: must contain "qcom,hidma-1.0" for initial HW or
+ "qcom,hidma-1.1"/"qcom,hidma-1.2" for MSI capable HW.
+- reg: Addresses for the transfer and event channel
+- interrupts: Should contain the event interrupt
+- desc-count: Number of asynchronous requests this channel can handle
+- iommus: required a iommu node
+
+Optional properties for MSI:
+- msi-parent : See the generic MSI binding described in
+ devicetree/bindings/interrupt-controller/msi.txt for a description of the
+ msi-parent property.
+
+Example:
+
+Hypervisor OS configuration:
+
+ hidma-mgmt@f9984000 = {
+ compatible = "qcom,hidma-mgmt-1.0";
+ reg = <0xf9984000 0x15000>;
+ dma-channels = <6>;
+ max-write-burst-bytes = <1024>;
+ max-read-burst-bytes = <1024>;
+ max-write-transactions = <31>;
+ max-read-transactions = <31>;
+ channel-reset-timeout-cycles = <0x500>;
+
+ hidma_24: dma-controller@5c050000 {
+ compatible = "qcom,hidma-1.0";
+ reg = <0 0x5c050000 0x0 0x1000>,

+ If both max-burst-mem-read and max-burst-mem-write are set, DMA_MEM_TO_MEM
+ will use the lower value.
+
+You can use dma-channels and dma-requests as described in dma.txt, although they

+description: |
+ The STM32 DMA is a general-purpose direct memory access controller capable of
+ supporting 8 independent DMA channels. Each channel can have up to 8 requests.
+ DMA clients connected to the STM32 DMA controller must use the format

+ 1. The channel id
+ 2. The request line number
+ 3. A 32bit mask specifying the DMA channel configuration which are device
+ dependent:
+ -bit 9: Peripheral Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 10: Memory Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 15: Peripheral Increment Offset Size
+ 0x0: offset size is linked to the peripheral bus width
+ 0x1: offset size is fixed to 4 (32-bit alignment)

+ 0x0: low

+ 0x3: full FIFO
+ -bit 2: DMA direct mode
+ 0x0: FIFO mode with threshold selectable with bit 0-1
+ 0x1: Direct mode: each DMA request immediately initiates a transfer
+ from/to the memory, FIFO is bypassed.
+ -bit 4: alternative DMA request/acknowledge protocol
+ 0x0: Use standard DMA ACK management, where ACK signal is maintained
+ up to the removal of request and transfer completion
+ 0x1: Use alternative DMA ACK management, where ACK de-assertion does
+ not wait for the de-assertion of the REQuest, ACK is only managed
+ by transfer completion. This must only be used on channels
+ managing transfers for STM32 USART/UART.

+- reg: Memory map for accessing module

+
+Notes:
+When requesting channel via ti,dra7-dma-crossbar, the DMA clinet must request

+description: |
+ The Block Copy DMA (BCDMA) is intended to perform similar functions as the TR
+ mode channels of K3 UDMA-P.
+ BCDMA includes block copy channels and Split channels.
+
+ Block copy channels mainly used for memory to memory transfers, but with
+ optional triggers a block copy channel can service peripherals by accessing
+ directly to memory mapped registers or area.
+
+ Split channels can be used to service PSI-L based peripherals.
+ The peripherals can be PSI-L native or legacy, non PSI-L native peripherals
+ with PDMAs. PDMA is tasked to act as a bridge between the PSI-L fabric and the
+ legacy peripheral.
+
+ PDMAs can be configured via BCDMA split channel's peer registers to match with
+ the configuration of the legacy peripheral.

+description: |
+ The UDMA-P is intended to perform similar (but significantly upgraded)
+ functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P
+ module supports the transmission and reception of various packet types.
+ The UDMA-P architecture facilitates the segmentation and reassembly of SoC DMA
+ data structure compliant packets to/from smaller data blocks that are natively
+ compatible with the specific requirements of each connected peripheral.
+ Multiple Tx and Rx channels are provided within the DMA which allow multiple
+ segmentation or reassembly operations to be ongoing. The DMA controller
+ maintains state information for each of the channels which allows packet
+ segmentation and reassembly operations to be time division multiplexed between
+ channels in order to share the underlying DMA hardware. An external DMA
+ scheduler is used to control the ordering and rate at which this multiplexing
+ occurs for Transmit operations. The ordering and rate of Receive operations
+ is indirectly controlled by the order in which blocks are pushed into the DMA
+ on the Rx PSI-L interface.
+
+ The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
+ channels. Channels in the UDMA-P can be configured to be either Packet-Based
+ or Third-Party channels on a channel by channel basis.
+
+ All transfers within NAVSS is done between PSI-L source and destination
+ threads.
+ The peripherals serviced by UDMA can be PSI-L native (sa2ul, cpsw, etc) or
+ legacy, non PSI-L native peripherals. In the later case a special, small PDMA
+ is tasked to act as a bridge between the PSI-L fabric and the legacy
+ peripheral.
+
+ PDMAs can be configured via UDMAP peer registers to match with the
+ configuration of the legacy peripheral.

+description: |+
+ This binding is intended for performance management of groups of devices or
+ CPUs that run in the same performance domain. Performance domains must not
+ be confused with power domains. A performance domain is defined by a set
+ of devices that always have to run at the same performance level. For a given
+ performance domain, there is a single point of control that affects all the
+ devices in the domain, making it impossible to set the performance level of
+ an individual device in the domain independently from other devices in
+ that domain. For example, a set of CPUs that share a voltage domain, and
+ have a common frequency control, is said to be in the same performance
+ domain.
+
+ This device tree binding can be used to bind performance domain consumer
+ devices with their performance domains provided by performance domain
+ providers. A performance domain provider can be represented by any node in
+ the device tree and can provide one or more performance domains. A consumer
+ node can refer to the provider by a phandle and a set of phandle arguments
+ (so called performance domain specifiers) of length specified by the
+ \#performance-domain-cells property in the performance domain provider node.

+* APM X-Gene SoC EDAC node
+
+EDAC node is defined to describe on-chip error detection and correction.
+The follow error types are supported:
+
+ memory controller - Memory controller
+ PMD (L1/L2) - Processor module unit (PMD) L1/L2 cache
+ L3 - L3 cache controller
+ SoC - SoC IP's such as Ethernet, SATA, and etc
+
+The following section describes the EDAC DT node binding.
+
+Required properties:
+- compatible : Shall be "apm,xgene-edac".
+- regmap-csw : Regmap of the CPU switch fabric (CSW) resource.
+- regmap-mcba : Regmap of the MCB-A (memory bridge) resource.
+- regmap-mcbb : Regmap of the MCB-B (memory bridge) resource.
+- regmap-efuse : Regmap of the PMD efuse resource.
+- regmap-rb : Regmap of the register bus resource. This property
+ is optional only for compatibility. If the RB
+ error conditions are not cleared, it will
+ continuously generate interrupt.
+- reg : First resource shall be the CPU bus (PCP) resource.
+- interrupts : Interrupt-specifier for MCU, PMD, L3, or SoC error
+ IRQ(s).
+
+Required properties for memory controller subnode:
+- compatible : Shall be "apm,xgene-edac-mc".
+- reg : First resource shall be the memory controller unit
+ (MCU) resource.
+- memory-controller : Instance number of the memory controller.
+
+Required properties for PMD subnode:
+- compatible : Shall be "apm,xgene-edac-pmd" or
+ "apm,xgene-edac-pmd-v2".
+- reg : First resource shall be the PMD resource.
+- pmd-controller : Instance number of the PMD controller.
+
+Required properties for L3 subnode:
+- compatible : Shall be "apm,xgene-edac-l3" or
+ "apm,xgene-edac-l3-v2".
+- reg : First resource shall be the L3 EDAC resource.
+
+Required properties for SoC subnode:
+- compatible : Shall be "apm,xgene-edac-soc-v1" for revision 1 or
+ "apm,xgene-edac-l3-soc" for general value reporting
+ only.

+Aspeed BMC SoC EDAC node
+
+The Aspeed BMC SoC supports DDR3 and DDR4 memory with and without ECC (error
+correction check).
+
+The memory controller supports SECDED (single bit error correction, double bit
+error detection) and single bit error auto scrubbing by reserving 8 bits for
+every 64 bit word (effectively reducing available memory to 8/9).
+
+Note, the bootloader must configure ECC mode in the memory controller.

+Altera SoCFPGA ECC Manager
+This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
+The ECC Manager counts and corrects single bit errors and counts/handles
+double bit errors which are uncorrectable.
+
+Cyclone5 and Arria5 ECC Manager
+Required Properties:
+- compatible : Should be "altr,socfpga-ecc-manager"
+- #address-cells: must be 1
+- #size-cells: must be 1
+- ranges : standard definition, should translate from local addresses
+
+Subcomponents:
+
+L2 Cache ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-l2-ecc"
+- reg : Address and size for ECC error interrupt clear registers.
+- interrupts : Should be single bit error interrupt, then double bit error
+ interrupt. Note the rising edge type.
+
+On Chip RAM ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-ocram-ecc"
+- reg : Address and size for ECC error interrupt clear registers.

+ };
+
+Arria10 SoCFPGA ECC Manager
+The Arria10 SoC ECC Manager handles the IRQs for each peripheral

+Stratix10 SoCFPGA ECC Manager (ARM64)
+The Stratix10 SoC ECC Manager handles the IRQs for each peripheral

+with SMC calls. Therefore the device tree is slightly different. Note
+that only 1 interrupt is sent in Stratix10 because the double bit errors
+are treated as SErrors in ARM64 instead of IRQs in ARM32.

+COREBOOT firmware information

+ - reg: Address and length of the following two memory regions, in order:
+ 1.) The coreboot table. This is a list of variable-sized descriptors

+ four bytes.
+ See coreboot's src/commonlib/include/commonlib/coreboot_tables.h for
+ details.
+ 2.) The CBMEM area. This is a downward-growing memory region used by
+ coreboot to dynamically allocate data structures that remain resident.
+ It may or may not include the coreboot table as one of its members. It
+ is identified by a root node descriptor with the magic number
+ 0xc0389481 that resides in the topmost 8 bytes of the area.
+ See coreboot's src/include/imd.h for details.

+
+maintainers:

+
+description:
+ The System Controller Firmware (SCFW) is a low-level system function
+ which runs on a dedicated Cortex-M core to provide power, clock, and
+ resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
+ (QM, QP), and i.MX8QX (QXP, DX).
+ The AP communicates with the SC using a multi-ported MU module found
+ in the LSIO subsystem. The current definition of this MU module provides
+ 5 remote AP connections to the SC to support up to 5 execution environments
+ (TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
+ with the LSIO DSC IP bus. The SC firmware will communicate with this MU
+ using the MSI bus.

+Intel Service Layer Driver for Stratix10 SoC
+============================================
+Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard
+processor system (HPS) and Secure Device Manager (SDM). When the FPGA is
+configured from HPS, there needs to be a way for HPS to notify SDM the
+location and size of the configuration data. Then SDM will get the
+configuration data from that location and perform the FPGA configuration.
+
+To meet the whole system security needs and support virtual machine requesting
+communication with SDM, only the secure world of software (EL3, Exception
+Layer 3) can interface with SDM. All software entities running on other
+exception layers must channel through the EL3 software whenever it needs
+service from SDM.
+
+Intel Stratix10 service layer driver, running at privileged exception level
+(EL1, Exception Layer 1), interfaces with the service providers and provides
+the services for FPGA configuration, QSPI, Crypto and warm reset. Service layer
+driver also manages secure monitor call (SMC) to communicate with secure monitor
+code running in EL3.
+
+Required properties:
+-------------------
+The svc node has the following mandatory properties, must be located under
+the firmware node.
+
+- compatible: "intel,stratix10-svc" or "intel,agilex-svc"
+- method: smc or hvc
+ smc - Secure Monitor Call
+ hvc - Hypervisor Call
+- memory-region:
+ phandle to the reserved memory node. See
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
+ for details
+
+Example:
+-------
+
+ reserved-memory {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ ranges;
+
+ service_reserved: svcbuffer@0 {
+ compatible = "shared-dma-pool";

+title: NVIDIA Tegra Boot and Power Management Processor (BPMP)
+
+maintainers:
+ - Thierry Reding <thierry.reding@gmail.com>
+ - Jon Hunter <jonathanh@nvidia.com>
+
+description: |
+ The BPMP is a specific processor in Tegra chip, which is designed for
+ booting process handling and offloading the power management, clock
+ management, and reset control tasks from the CPU. The binding document
+ defines the resources that would be used by the BPMP firmware driver,
+ which can create the interprocessor communication (IPC) between the
+ CPU and BPMP.
+
+ This node is a mailbox consumer. See the following files for details
+ of the mailbox subsystem, and the specifiers implemented by the
+ relevant provider(s):
+
+ - .../mailbox/mailbox.txt
+ - .../mailbox/nvidia,tegra186-hsp.yaml
+
+ This node is a clock, power domain, and reset provider. See the
+ following files for general documentation of those features, and the
+ specifiers implemented by this node:
+
+ - .../clock/clock-bindings.txt
+ - <dt-bindings/clock/tegra186-clock.h>
+ - ../power/power-domain.yaml
+ - <dt-bindings/power/tegra186-powergate.h>
+ - .../reset/reset.txt
+ - <dt-bindings/reset/tegra186-reset.h>
+
+ The BPMP implements some services which must be represented by
+ separate nodes. For example, it can provide access to certain I2C
+ controllers, and the I2C bindings represent each I2C controller as a
+ device tree node. Such nodes should be nested directly inside the main
+ BPMP node.
+
+ Software can determine whether a child node of the BPMP node
+ represents a device by checking for a compatible property. Any node
+ with a compatible property represents a device that can be
+ instantiated. Nodes without a compatible property may be used to
+ provide configuration information regarding the BPMP itself, although
+ no such configuration nodes are currently defined by this binding.
+
+ The BPMP firmware defines no single global name-/numbering-space for
+ such services. Put another way, the numbering scheme for I2C buses is
+ distinct from the numbering scheme for any other service the BPMP may
+ provide (e.g. a future hypothetical SPI bus service). As such, child
+ device nodes will have no reg property, and the BPMP node will have no
+ "#address-cells" or "#size-cells" property.
+
+ The shared memory area for the IPC TX and RX between CPU and BPMP are
+ predefined and work on top of either sysram, which is an SRAM inside the
+ chip, or in normal SDRAM.
+ See ".../sram/sram.yaml" for the bindings for the SRAM case.
+ See "../reserved-memory/nvidia,tegra264-bpmp-shmem.yaml" for bindings for
+ the SDRAM case.

+in Tegra210 SoC. It is designed to handle the early stages of the boot
+process as well as to assisting in entering deep low power state
+(suspend to ram), and also offloading DRAM memory clock scaling on
+some platforms. The binding document defines the resources that would
+be used by the BPMP T210 firmware driver, which can create the
+interprocessor communication (IPC) between the CPU and BPMP.
+
+Required properties:
+- compatible
+ Array of strings
+ One of:
+ - "nvidia,tegra210-bpmp"
+- reg: physical base address and length for HW synchornization primitives
+ 1) base address and length to Tegra 'atomics' hardware
+ 2) base address and length to Tegra 'semaphore' hardware
+- interrupts: specifies the interrupt number for receiving messages ("rx")
+ and for triggering messages ("tx")
+
+Optional properties:
+- #clock-cells : Should be 1 for platforms where DRAM clock control is
+ offloaded to bpmp.
+
+Example:

+Introduction
+============
+
+FPGA Regions represent FPGA's and partial reconfiguration regions of FPGA's in
+the Device Tree. FPGA Regions provide a way to program FPGAs under device tree
+control.
+
+This device tree binding document hits some of the high points of FPGA usage and
+attempts to include terminology used by both major FPGA manufacturers. This
+document isn't a replacement for any manufacturers specifications for FPGA
+usage.
+
+
+Terminology
+===========
+
+Full Reconfiguration
+ * The entire FPGA is programmed.
+
+Partial Reconfiguration (PR)
+ * A section of an FPGA is reprogrammed while the rest of the FPGA is not
+ affected.
+ * Not all FPGA's support PR.
+
+Partial Reconfiguration Region (PRR)
+ * Also called a "reconfigurable partition"
+ * A PRR is a specific section of an FPGA reserved for reconfiguration.
+ * A base (or static) FPGA image may create a set of PRR's that later may
+ be independently reprogrammed many times.
+ * The size and specific location of each PRR is fixed.
+ * The connections at the edge of each PRR are fixed. The image that is loaded
+ into a PRR must fit and must use a subset of the region's connections.
+ * The busses within the FPGA are split such that each region gets its own
+ branch that may be gated independently.
+
+Persona
+ * Also called a "partial bit stream"
+ * An FPGA image that is designed to be loaded into a PRR. There may be
+ any number of personas designed to fit into a PRR, but only one at at time
+ may be loaded.
+ * A persona may create more regions.
+
+FPGA Bridge
+ * FPGA Bridges gate bus signals between a host and FPGA.
+ * FPGA Bridges should be disabled while the FPGA is being programmed to
+ prevent spurious signals on the cpu bus and to the soft logic.
+ * FPGA bridges may be actual hardware or soft logic on an FPGA.
+ * During Full Reconfiguration, hardware bridges between the host and FPGA
+ will be disabled.
+ * During Partial Reconfiguration of a specific region, that region's bridge
+ will be used to gate the busses. Traffic to other regions is not affected.
+ * In some implementations, the FPGA Manager transparently handles gating the
+ buses, eliminating the need to show the hardware FPGA bridges in the
+ device tree.
+ * An FPGA image may create a set of reprogrammable regions, each having its
+ own bridge and its own split of the busses in the FPGA.
+
+FPGA Manager
+ * An FPGA Manager is a hardware block that programs an FPGA under the control
+ of a host processor.
+
+Base Image
+ * Also called the "static image"
+ * An FPGA image that is designed to do full reconfiguration of the FPGA.
+ * A base image may set up a set of partial reconfiguration regions that may
+ later be reprogrammed.

+Figure 1: An FPGA set up with a base image that created three regions. Each
+region (PRR0-2) gets its own split of the busses that is independently gated by
+a soft logic bridge (Bridge0-2) in the FPGA. The contents of each PRR can be
+reprogrammed independently while the rest of the system continues to function.
+
+
+Sequence
+========
+
+When a DT overlay that targets an FPGA Region is applied, the FPGA Region will
+do the following:
+
+ 1. Disable appropriate FPGA bridges.
+ 2. Program the FPGA using the FPGA manager.
+ 3. Enable the FPGA bridges.
+ 4. The Device Tree overlay is accepted into the live tree.
+ 5. Child devices are populated.
+
+When the overlay is removed, the child nodes will be removed and the FPGA Region
+will disable the bridges.
+
+
+FPGA Region
+===========
+
+FPGA Regions represent FPGA's and FPGA PR regions in the device tree. An FPGA
+Region brings together the elements needed to program on a running system and
+add the child devices:
+
+ * FPGA Manager
+ * FPGA Bridges
+ * image-specific information needed to to the programming.
+ * child nodes
+
+The intended use is that a Device Tree overlay (DTO) can be used to reprogram an
+FPGA while an operating system is running.
+
+An FPGA Region that exists in the live Device Tree reflects the current state.
+If the live tree shows a "firmware-name" property or child nodes under an FPGA
+Region, the FPGA already has been programmed. A DTO that targets an FPGA Region
+and adds the "firmware-name" property is taken as a request to reprogram the
+FPGA. After reprogramming is successful, the overlay is accepted into the live
+tree.
+
+The base FPGA Region in the device tree represents the FPGA and supports full
+reconfiguration. It must include a phandle to an FPGA Manager. The base
+FPGA region will be the child of one of the hardware bridges (the bridge that
+allows register access) between the cpu and the FPGA. If there are more than
+one bridge to control during FPGA programming, the region will also contain a
+list of phandles to the additional hardware FPGA Bridges.
+
+For partial reconfiguration (PR), each PR region will have an FPGA Region.
+These FPGA regions are children of FPGA bridges which are then children of the
+base FPGA region. The "Full Reconfiguration to add PRR's" example below shows
+this.
+
+If an FPGA Region does not specify an FPGA Manager, it will inherit the FPGA
+Manager specified by its ancestor FPGA Region. This supports both the case
+where the same FPGA Manager is used for all of an FPGA as well the case where
+a different FPGA Manager is used for each region.
+
+FPGA Regions do not inherit their ancestor FPGA regions' bridges. This prevents
+shutting down bridges that are upstream from the other active regions while one
+region is getting reconfigured (see Figure 1 above). During PR, the FPGA's
+hardware bridges remain enabled. The PR regions' bridges will be FPGA bridges
+within the static image of the FPGA.
+
+Required properties:
+- compatible : should contain "fpga-region"
+- fpga-mgr : should contain a phandle to an FPGA Manager. Child FPGA Regions
+ inherit this property from their ancestor regions. An fpga-mgr property
+ in a region will override any inherited FPGA manager.
+- #address-cells, #size-cells, ranges : must be present to handle address space
+ mapping for child nodes.
+
+Optional properties:
+- firmware-name : should contain the name of an FPGA image file located on the
+ firmware search path. If this property shows up in a live device tree
+ it indicates that the FPGA has already been programmed with this image.
+ If this property is in an overlay targeting an FPGA region, it is a
+ request to program the FPGA with that image.
+- fpga-bridges : should contain a list of phandles to FPGA Bridges that must be
+ controlled during FPGA programming along with the parent FPGA bridge.
+ This property is optional if the FPGA Manager handles the bridges.
+ If the fpga-region is the child of an fpga-bridge, the list should not
+ contain the parent bridge.
+- partial-fpga-config : boolean, set if partial reconfiguration is to be done,
+ otherwise full reconfiguration is done.
+- external-fpga-config : boolean, set if the FPGA has already been configured
+ prior to OS boot up.
+- encrypted-fpga-config : boolean, set if the bitstream is encrypted
+- region-unfreeze-timeout-us : The maximum time in microseconds to wait for
+ bridges to successfully become enabled after the region has been
+ programmed.
+- region-freeze-timeout-us : The maximum time in microseconds to wait for
+ bridges to successfully become disabled before the region has been
+ programmed.
+- config-complete-timeout-us : The maximum time in microseconds time for the
+ FPGA to go to operating mode after the region has been programmed.
+- child nodes : devices in the FPGA after programming.
+
+In the example below, when an overlay is applied targeting fpga-region0,
+fpga_mgr is used to program the FPGA. Two bridges are controlled during
+programming: the parent fpga_bridge0 and fpga_bridge1. Because the region is
+the child of fpga_bridge0, only fpga_bridge1 needs to be specified in the
+fpga-bridges property. During programming, these bridges are disabled, the
+firmware specified in the overlay is loaded to the FPGA using the FPGA manager
+specified in the region. If FPGA programming succeeds, the bridges are
+reenabled and the overlay makes it into the live device tree. The child devices
+are then populated. If FPGA programming fails, the bridges are left disabled
+and the overlay is rejected. The overlay's ranges property maps the lwhps
+bridge's region (0xff200000) and the hps bridge's region (0xc0000000) for use by
+the two child devices.
+
+Example:
+Base tree contains:
+
+ fpga_mgr: fpga-mgr@ff706000 {
+ compatible = "altr,socfpga-fpga-mgr";
+ reg = <0xff706000 0x1000

+
+ onchip-memory {
+ device_type = "memory";
+ compatible = "altr,onchipmem-15.1";
+ reg = <0x0 0x10000>;
+ };
+};
+
+
+Supported Use Models
+====================
+
+In all cases the live DT must have the FPGA Manager, FPGA Bridges (if any), and
+a FPGA Region. The target of the Device Tree Overlay is the FPGA Region. Some
+uses are specific to an FPGA device.
+
+ * No FPGA Bridges
+ In this case, the FPGA Manager which programs the FPGA also handles the
+ bridges behind the scenes. No FPGA Bridge devices are needed for full
+ reconfiguration.
+
+ * Full reconfiguration with hardware bridges
+ In this case, there are hardware bridges between the processor and FPGA that
+ need to be controlled during full reconfiguration. Before the overlay is
+ applied, the live DT must include the FPGA Manager, FPGA Bridges, and a
+ FPGA Region. The FPGA Region is the child of the bridge that allows
+ register access to the FPGA. Additional bridges may be listed in a
+ fpga-bridges property in the FPGA region or in the device tree overlay.
+
+ * Partial reconfiguration with bridges in the FPGA
+ In this case, the FPGA will have one or more PRR's that may be programmed
+ separately while the rest of the FPGA can remain active. To manage this,
+ bridges need to exist in the FPGA that can gate the buses going to each FPGA
+ region while the buses are enabled for other sections. Before any partial
+ reconfiguration can be done, a base FPGA image must be loaded which includes
+ PRR's with FPGA bridges. The device tree should have an FPGA region for each
+ PRR.
+
+Device Tree Examples
+====================
+
+The intention of this section is to give some simple examples, focusing on
+the placement of the elements detailed above, especially:
+ * FPGA Manager
+ * FPGA Bridges
+ * FPGA Region
+ * ranges
+ * target-path or target
+
+For the purposes of this section, I'm dividing the Device Tree into two parts,
+each with its own requirements. The two parts are:
+ * The live DT prior to the overlay being added
+ * The DT overlay
+
+The live Device Tree must contain an FPGA Region, an FPGA Manager, and any FPGA
+Bridges. The FPGA Region's "fpga-mgr" property specifies the manager by phandle
+to handle programming the FPGA. If the FPGA Region is the child of another FPGA
+Region, the parent's FPGA Manager is used. If FPGA Bridges need to be involved,
+they are specified in the FPGA Region by the "fpga-bridges" property. During
+FPGA programming, the FPGA Region will disable the bridges that are in its
+"fpga-bridges" list and will re-enable them after FPGA programming has
+succeeded.
+
+The Device Tree Overlay will contain:
+ * "target-path" or "target"
+ The insertion point where the contents of the overlay will go into the
+ live tree. target-path is a full path, while target is a phandle.
+ * "ranges"
+ The address space mapping from processor to FPGA bus(ses).
+ * "firmware-name"
+ Specifies the name of the FPGA image file on the firmware search
+ path. The search path is described in the firmware class documentation.
+ * "partial-fpga-config"
+ This binding is a boolean and should be present if partial reconfiguration
+ is to be done.
+ * child nodes corresponding to hardware that will be loaded in this region of
+ the FPGA.
+

+Device Tree Example: Partial Reconfiguration
+============================================
+
+This example reprograms one of the PRR's set up in the previous example.
+
+The sequence that occurs when this overlay is similar to the above, the only
+differences are that the FPGA is partially reconfigured due to the
+"partial-fpga-config" boolean and the only bridge that is controlled during
+programming is the FPGA based bridge of fpga_region1.
+
+/dts-v1/;
+/plugin/;
+
+&fpga_region1 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ firmware-name = "soc_image2.rbf";
+ partial-fpga-config;
+
+ gpio@10040 {
+ compatible = "altr,pio-1.0";
+ reg = <0x10040 0x20>;
+ clocks = <0x2>;
+ altr,ngpio = <0x4>;
+ #gpio-cells = <0x2>;
+ gpio-controller;
+ };
+};
+
+Constraints
+===========
+
+It is beyond the scope of this document to fully describe all the FPGA design
+constraints required to make partial reconfiguration work[1] [2] [3], but a few
+deserve quick mention.
+
+A persona must have boundary connections that line up with those of the partition
+or region it is designed to go into.
+
+During programming, transactions through those connections must be stopped and
+the connections must be held at a fixed logic level. This can be achieved by
+FPGA Bridges that exist on the FPGA fabric prior to the partial reconfiguration.

+description: |
+ The Xilinx LogiCORE Partial Reconfig(PR) Decoupler manages one or more
+ decouplers/fpga bridges. The controller can decouple/disable the bridges
+ which prevents signal changes from passing through the bridge. The controller
+ can also couple / enable the bridges which allows traffic to pass through the
+ bridge normally.
+ Xilinx LogiCORE Dynamic Function eXchange(DFX) AXI shutdown manager Softcore
+ is compatible with the Xilinx LogiCORE pr-decoupler. The Dynamic Function
+ eXchange AXI shutdown manager prevents AXI traffic from passing through the
+ bridge. The controller safely handles AXI4MM and AXI4-Lite interfaces on a
+ Reconfigurable Partition when it is undergoing dynamic reconfiguration,
+ preventing the system deadlock that can occur if AXI transactions are
+ interrupted by DFX.
+ Please refer to fpga-region.txt and fpga-bridge.txt in this directory for
+ common binding part and usage.

+FSI bus & engine generic device tree bindings
+=============================================
+
+The FSI bus is probe-able, so the OS is able to enumerate FSI slaves, and
+engines within those slaves. However, we have a facility to match devicetree
+nodes to probed engines. This allows for fsi engines to expose non-probeable
+busses, which are then exposed by the device tree. For example, an FSI engine
+that is an I2C master - the I2C bus can be described by the device tree under
+the engine's device tree node.
+
+FSI masters may require their own DT nodes (to describe the master HW itself);
+that requirement is defined by the master's implementation, and is described by
+the fsi-master-* binding specifications.
+
+Under the masters' nodes, we can describe the bus topology using nodes to
+represent the FSI slaves and their slave engines. As a basic outline:
+
+ fsi-master {
+ /* top-level of FSI bus topology, bound to an FSI master driver and
+ * exposes an FSI bus */
+
+ fsi-slave@<link,id> {
+ /* this node defines the FSI slave device, and is handled
+ * entirely with FSI core code */
+
+ fsi-slave-engine@<addr> {
+ /* this node defines the engine endpoint & address range, which
+ * is bound to the relevant fsi device driver */
+ ...
+ };
+
+ fsi-slave-engine@<addr> {
+ ...
+ };
+
+ };
+ };
+
+Note that since the bus is probe-able, some (or all) of the topology may
+not be described; this binding only provides an optional facility for
+adding subordinate device tree nodes as children of FSI engines.
+
+FSI masters
+-----------
+
+FSI master nodes declare themselves as such with the "fsi-master" compatible
+value. It's likely that an implementation-specific compatible value will
+be needed as well, for example:
+
+ compatible = "fsi-master-gpio", "fsi-master";
+
+Since the master nodes describe the top-level of the FSI topology, they also
+need to declare the FSI-standard addressing scheme. This requires two cells for
+addresses (link index and slave ID), and no size:
+
+ #address-cells = <2>;
+ #size-cells = <0>;
+
+An optional boolean property can be added to indicate that a particular master
+should not scan for connected devices at initialization time. This is
+necessary in cases where a scan could cause arbitration issues with other
+masters that may be present on the bus.
+
+ no-scan-on-init;
+
+FSI slaves
+----------
+
+Slaves are identified by a (link-index, slave-id) pair, so require two cells
+for an address identifier. Since these are not a range, no size cells are
+required. For an example, a slave on link 1, with ID 2, could be represented
+as:
+
+ cfam@1,2 {
+ reg = <1 2>;
+ [...];
+ }
+
+Each slave provides an address-space, under which the engines are accessible.
+That address space has a maximum of 23 bits, so we use one cell to represent
+addresses and sizes in the slave address space:
+
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+Optionally, a slave can provide a global unique chip ID which is used to
+identify the physical location of the chip in a system specific way
+
+ chip-id = <0>;
+
+FSI engines (devices)
+---------------------
+
+Engines are identified by their address under the slaves' address spaces. We
+use a single cell for address and size. Engine nodes represent the endpoint
+FSI device, and are passed to those FSI device drivers' ->probe() functions.
+
+For example, for a slave using a single 0x400-byte page starting at address
+0xc00:
+
+ engine@c00 {
+ reg = <0xc00 0x400>;
+ };
+
+
+Full example
+------------
+
+Here's an example that illustrates:
+ - an FSI master
+ - connected to an FSI slave
+ - that contains an engine that is an I2C master
+ - connected to an I2C EEPROM
+
+The FSI master may be connected to additional slaves, and slaves may have
+additional engines, but they don't necessarily need to be describe in the
+device tree if no extra platform information is required.
+
+ /* The GPIO-based FSI master node, describing the top level of the
+ * FSI bus
+ */
+ gpio-fsi {
+ compatible = "fsi-master-gpio", "fsi-master";
+ #address-cells = <2>;
+ #size-cells = <0>;
+
+ /* A FSI slave (aka. CFAM) at link 0, ID 0. */
+ cfam@0,0 {
+ reg = <0 0>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ chip-id = <0>;
+
+ /* FSI engine at 0xc00, using a single page. In this example,
+ * it's an I2C master controller, so subnodes describe the
+ * I2C bus.
+ */
+ i2c-controller@c00 {
+ reg = <0xc00 0x400>;
+
+ /* Engine-specific data. In this case, we're describing an
+ * I2C bus, so we're conforming to the generic I2C binding
+ */
+ compatible = "some-vendor,fsi-i2c-controller";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* I2C endpoint device: an Atmel EEPROM */
+ eeprom@50 {
+ compatible = "atmel,24c256";
+ reg = <0x50>;
+ pagesize = <64>;
+ };
+ };
+ };
+ };

+GPIO controllers on MPC8xxx SoCs
+
+This is for the non-QE/CPM/GUTs GPIO controllers as found on
+8349, 8572, 8610 and compatible.
+
+Every GPIO controller node must have #gpio-cells property defined,
+this information will be used to translate gpio-specifiers.
+See bindings/gpio/gpio.txt for details of how to specify GPIO
+information for devices.
+
+The GPIO module usually is connected to the SoC's internal interrupt
+controller, see bindings/interrupt-controller/interrupts.txt (the
+interrupt client nodes section) for details how to specify this GPIO
+module's interrupt.
+
+The GPIO module may serve as another interrupt controller (cascaded to
+the SoC's internal interrupt controller). See the interrupt controller
+nodes section in bindings/interrupt-controller/interrupts.txt for
+details.
+
+Required properties:
+- compatible: "fsl,<chip>-gpio" followed by "fsl,mpc8349-gpio"
+ for 83xx, "fsl,mpc8572-gpio" for 85xx, or
+ "fsl,mpc8610-gpio" for 86xx.
+- #gpio-cells: Should be two. The first cell is the pin number
+ and the second cell is used to specify optional
+ parameters (currently unused).
+- interrupts: Interrupt mapping for GPIO IRQ.
+- gpio-controller: Marks the port as GPIO controller.
+
+Optional properties:
+- interrupt-controller: Empty boolean property which marks the GPIO
+ module as an IRQ controller.
+- #interrupt-cells: Should be two. Defines the number of integer
+ cells required to specify an interrupt within
+ this interrupt controller. The first cell
+ defines the pin number, the second cell
+ defines additional flags (trigger type,
+ trigger polarity). Note that the available
+ set of trigger conditions supported by the
+ GPIO module depends on the actual SoC.
+
+Example of gpio-controller nodes for a MPC8347 SoC:
+
+ gpio1: gpio-controller@c00 {
+ #gpio-cells = <2>;
+ compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
+ reg = <0xc00 0x100>;
+ interrupt-parent = <&ipic>;
+ interrupts = <74 0x8>;
+ gpio-controller;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ };
+
+ gpio2: gpio-controller@d00 {
+ #gpio-cells = <2>;
+ compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
+ reg = <0xd00 0x100>;
+ interrupt-parent = <&ipic>;
+ interrupts = <75 0x8>;
+ gpio-controller;
+ };
+
+Example of a peripheral using the GPIO module as an IRQ controller:
+
+ funkyfpga@0 {
+ compatible = "funky-fpga";
+ ...
+ interrupt-parent = <&gpio1>;
+ interrupts = <4 3>;
+ };

+Altera GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "altr,pio-1.0"
+- reg: Physical base address and length of the controller's registers.
+- #gpio-cells : Should be 2
+ - The first cell is the gpio offset number.
+ - The second cell is reserved and is currently unused.
+- gpio-controller : Marks the device node as a GPIO controller.
+- interrupt-controller: Mark the device node as an interrupt controller
+- #interrupt-cells : Should be 2. The interrupt type is fixed in the hardware.
+ - The first cell is the GPIO offset number within the GPIO controller.
+ - The second cell is the interrupt trigger type and level flags.
+- interrupts: Specify the interrupt.
+- altr,interrupt-type: Specifies the interrupt trigger type the GPIO
+ hardware is synthesized. This field is required if the Altera GPIO controller
+ used has IRQ enabled as the interrupt type is not software controlled,
+ but hardware synthesized. Required if GPIO is used as an interrupt
+ controller. The value is defined in <dt-bindings/interrupt-controller/irq.h>
+ Only the following flags are supported:
+ IRQ_TYPE_EDGE_RISING
+ IRQ_TYPE_EDGE_FALLING
+ IRQ_TYPE_EDGE_BOTH
+ IRQ_TYPE_LEVEL_HIGH
+
+Optional properties:
+- altr,ngpio: Width of the GPIO bank. This defines how many pins the
+ GPIO device has. Ranges between 1-32. Optional and defaults to 32 if not
+ specified.
+
+Example:
+
+gpio_altr: gpio@ff200000 {

+Keystone 2 DSP GPIO controller bindings
+
+HOST OS userland running on ARM can send interrupts to DSP cores using
+the DSP GPIO controller IP. It provides 28 IRQ signals per each DSP core.
+This is one of the component used by the IPC mechanism used on Keystone SOCs.
+
+For example TCI6638K2K SoC has 8 DSP GPIO controllers:
+ - 8 for C66x CorePacx CPUs 0-7
+
+Keystone 2 DSP GPIO controller has specific features:
+- each GPIO can be configured only as output pin;
+- setting GPIO value to 1 causes IRQ generation on target DSP core;
+- reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
+ pending.
+
+Required Properties:
+- compatible: should be "ti,keystone-dsp-gpio"
+- ti,syscon-dev: phandle/offset pair. The phandle to syscon used to
+ access device state control registers and the offset of device's specific
+ registers within device state control registers range.
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be 2.
+
+Please refer to gpio.txt in this directory for details of the common GPIO
+bindings used by client devices.
+
+Example:
+ dspgpio0: keystone_dsp_gpio@2620240 {
+ compatible = "ti,keystone-dsp-gpio";
+ ti,syscon-dev = <&devctrl 0x240>;
+ gpio-controller;

+Aeroflex Gaisler GRGPIO General Purpose I/O cores.
+
+The GRGPIO GPIO core is available in the GRLIB VHDL IP core library.
+
+Note: In the ordinary environment for the GRGPIO core, a Leon SPARC system,
+these properties are built from information in the AMBA plug&play.
+
+Required properties:
+
+- name : Should be "GAISLER_GPIO" or "01_01a"
+
+- reg : Address and length of the register set for the device
+
+- interrupts : Interrupt numbers for this device
+
+Optional properties:
+
+- nbits : The number of gpio lines. If not present driver assumes 32 lines.
+
+- irqmap : An array with an index for each gpio line. An index is either a valid
+ index into the interrupts property array, or 0xffffffff that indicates
+ no irq for that line. Driver provides no interrupt support if not
+ present.
+
+For further information look in the documentation for the GLIB IP core library:

+
+description: |
+ The Freescale MXS GPIO controller is part of MXS PIN controller.
+ The GPIOs are organized in port/bank, each port consists of 32 GPIOs.
+ As the GPIO controller is embedded in the PIN controller and all the
+ GPIO ports share the same IO space with PIN controller, the GPIO node
+ will be represented as sub-nodes of MXS pinctrl node.

+Generic Parallel-in/Serial-out Shift Register GPIO Driver
+
+This binding describes generic parallel-in/serial-out shift register
+devices that can be used for GPI (General Purpose Input). This includes
+SN74165 serial-out shift registers and the SN65HVS88x series of
+industrial serializers.
+
+Required properties:
+ - compatible : Should be "pisosr-gpio".
+ - gpio-controller : Marks the device node as a GPIO controller.
+ - #gpio-cells : Should be two. For consumer use see gpio.txt.
+
+Optional properties:
+ - ngpios : Number of used GPIO lines (0..n-1), default is 8.
+ - load-gpios : GPIO pin specifier attached to load enable, this
+ pin is pulsed before reading from the device to
+ load input pin values into the device.
+
+For other required and optional properties of SPI slave
+nodes please refer to ../spi/spi-bus.txt.
+
+Example:
+
+ gpio@0 {
+ compatible = "ti,sn65hvs882", "pisosr-gpio";
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ load-gpios = <&gpio2 23 GPIO_ACTIVE_LOW>;

+Specifying GPIO information for devices
+=======================================
+
+1) gpios property
+-----------------
+
+GPIO properties should be named "[<name>-]gpios", with <name> being the purpose
+of this GPIO for the device. While a non-existent <name> is considered valid
+for compatibility reasons (resolving to the "gpios" property), it is not allowed
+for new bindings. Also, GPIO properties named "[<name>-]gpio" are valid and old
+bindings use it, but are only supported for compatibility reasons and should not
+be used for newer bindings since it has been deprecated.
+
+GPIO properties can contain one or more GPIO phandles, but only in exceptional
+cases should they contain more than one. If your device uses several GPIOs with
+distinct functions, reference each of them under its own property, giving it a
+meaningful name. The only case where an array of GPIOs is accepted is when
+several GPIOs serve the same function (e.g. a parallel data line).
+
+The exact purpose of each gpios property must be documented in the device tree
+binding of the device.
+
+The following example could be used to describe GPIO pins used as device enable
+and bit-banged data signals:
+
+ gpio1: gpio1 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+ [...]
+
+ data-gpios = <&gpio1 12 0>,
+ <&gpio1 13 0>,
+ <&gpio1 14 0>,
+ <&gpio1 15 0>;
+
+In the above example, &gpio1 uses 2 cells to specify a gpio. The first cell is
+a local offset to the GPIO line and the second cell represent consumer flags,
+such as if the consumer desire the line to be active low (inverted) or open
+drain. This is the recommended practice.
+
+The exact meaning of each specifier cell is controller specific, and must be
+documented in the device tree binding for the device, but it is strongly
+recommended to use the two-cell approach.
+
+Most controllers are specifying a generic flag bitfield in the last cell, so
+for these, use the macros defined in
+include/dt-bindings/gpio/gpio.h whenever possible:
+
+Example of a node using GPIOs:
+
+ node {
+ enable-gpios = <&qe_pio_e 18 GPIO_ACTIVE_HIGH>;
+ };
+
+GPIO_ACTIVE_HIGH is 0, so in this example gpio-specifier is "18 0" and encodes
+GPIO pin number, and GPIO flags as accepted by the "qe_pio_e" gpio-controller.
+
+Optional standard bitfield specifiers for the last cell:
+
+- Bit 0: 0 means active high, 1 means active low
+- Bit 1: 0 mean push-pull wiring, see:
+ https://en.wikipedia.org/wiki/Push-pull_output
+ 1 means single-ended wiring, see:
+ https://en.wikipedia.org/wiki/Single-ended_triode
+- Bit 2: 0 means open-source, 1 means open drain, see:
+ https://en.wikipedia.org/wiki/Open_collector
+- Bit 3: 0 means the output should be maintained during sleep/low-power mode
+ 1 means the output state can be lost during sleep/low-power mode
+- Bit 4: 0 means no pull-up resistor should be enabled
+ 1 means a pull-up resistor should be enabled
+ This setting only applies to hardware with a simple on/off
+ control for pull-up configuration. If the hardware has more
+ elaborate pull-up configuration, it should be represented
+ using a pin control binding.
+- Bit 5: 0 means no pull-down resistor should be enabled
+ 1 means a pull-down resistor should be enabled
+ This setting only applies to hardware with a simple on/off
+ control for pull-down configuration. If the hardware has more
+ elaborate pull-down configuration, it should be represented
+ using a pin control binding.
+
+1.1) GPIO specifier best practices
+----------------------------------
+
+A gpio-specifier should contain a flag indicating the GPIO polarity; active-
+high or active-low. If it does, the following best practices should be
+followed:
+
+The gpio-specifier's polarity flag should represent the physical level at the
+GPIO controller that achieves (or represents, for inputs) a logically asserted
+value at the device. The exact definition of logically asserted should be
+defined by the binding for the device. If the board inverts the signal between
+the GPIO controller and the device, then the gpio-specifier will represent the
+opposite physical level than the signal at the device's pin.
+
+When the device's signal polarity is configurable, the binding for the
+device must either:
+
+a) Define a single static polarity for the signal, with the expectation that
+any software using that binding would statically program the device to use
+that signal polarity.
+
+The static choice of polarity may be either:
+
+a1) (Preferred) Dictated by a binding-specific DT property.
+
+or:
+
+a2) Defined statically by the DT binding itself.
+
+In particular, the polarity cannot be derived from the gpio-specifier, since
+that would prevent the DT from separately representing the two orthogonal
+concepts of configurable signal polarity in the device, and possible board-
+level signal inversion.
+
+or:
+
+b) Pick a single option for device signal polarity, and document this choice
+in the binding. The gpio-specifier should represent the polarity of the signal
+(at the GPIO controller) assuming that the device is configured for this
+particular signal polarity choice. If software chooses to program the device
+to generate or receive a signal of the opposite polarity, software will be
+responsible for correctly interpreting (inverting) the GPIO signal at the GPIO
+controller.
+
+2) gpio-controller nodes
+------------------------
+
+Every GPIO controller node must contain both an empty "gpio-controller"
+property, and a #gpio-cells integer property, which indicates the number of
+cells in a gpio-specifier.
+
+Some system-on-chips (SoCs) use the concept of GPIO banks. A GPIO bank is an
+instance of a hardware IP core on a silicon die, usually exposed to the
+programmer as a coherent range of I/O addresses. Usually each such bank is
+exposed in the device tree as an individual gpio-controller node, reflecting
+the fact that the hardware was synthesized by reusing the same IP block a
+few times over.
+
+Optionally, a GPIO controller may have a "ngpios" property. This property
+indicates the number of in-use slots of available slots for GPIOs. The
+typical example is something like this: the hardware register is 32 bits
+wide, but only 18 of the bits have a physical counterpart. The driver is
+generally written so that all 32 bits can be used, but the IP block is reused
+in a lot of designs, some using all 32 bits, some using 18 and some using
+12. In this case, setting "ngpios = <18>;" informs the driver that only the
+first 18 GPIOs, at local offset 0 .. 17, are in use.
+
+If these GPIOs do not happen to be the first N GPIOs at offset 0...N-1, an
+additional set of tuples is needed to specify which GPIOs are unusable, with
+the gpio-reserved-ranges binding. This property indicates the start and size
+of the GPIOs that can't be used.
+
+Optionally, a GPIO controller may have a "gpio-line-names" property. This is
+an array of strings defining the names of the GPIO lines going out of the
+GPIO controller.
+
+For lines which are routed to on-board devices, this name should be
+the most meaningful producer name for the system, such as a rail name
+indicating the usage. Package names, such as a pin name, are discouraged:
+such lines have opaque names (since they are by definition general-purpose)
+and such names are usually not very helpful. For example "MMC-CD", "Red LED
+Vdd" and "ethernet reset" are reasonable line names as they describe what
+the line is used for. "GPIO0" is not a good name to give to a GPIO line
+that is hard-wired to a specific device.
+
+However, in the case of lines that are routed to a general purpose header
+(e.g. the Raspberry Pi 40-pin header), and therefore are not hard-wired to
+specific devices, using a pin number or the names on the header is fine
+provided these are real (preferably unique) names. Using an SoC's pad name
+or package name, or names made up from kernel-internal software constructs,
+are strongly discouraged. For example "pin8 [gpio14/uart0_txd]" is fine
+if the board's documentation labels pin 8 as such. However "PortB_24" (an
+example of a name from an SoC's reference manual) would not be desirable.
+
+In either case placeholders are discouraged: rather use the "" (blank
+string) if the use of the GPIO line is undefined in your design. Ideally,
+try to add comments to the dts file describing the naming the convention
+you have chosen, and specifying from where the names are derived.
+
+The names are assigned starting from line offset 0, from left to right,
+from the passed array. An incomplete array (where the number of passed
+names is less than ngpios) will be used up until the last provided valid
+line index.
+
+Example:
+
+gpio-controller@00000000 {
+ compatible = "foo";
+ reg = <0x00000000 0x1000>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ ngpios = <18>;
+ gpio-reserved-ranges = <0 4>, <12 2>;
+ gpio-line-names = "MMC-CD", "MMC-WP", "VDD eth", "RST eth", "LED R",
+ "LED G", "LED B", "Col A", "Col B", "Col C", "Col D",
+ "Row A", "Row B", "Row C", "Row D", "NMI button",
+ "poweroff", "reset";
+}
+
+The GPIO chip may contain GPIO hog definitions. GPIO hogging is a mechanism
+providing automatic GPIO request and configuration as part of the
+gpio-controller's driver probe function.
+
+Each GPIO hog definition is represented as a child node of the GPIO controller.
+Required properties:
+- gpio-hog: A property specifying that this child node represents a GPIO hog.
+- gpios: Store the GPIO information (id, flags, ...) for each GPIO to
+ affect. Shall contain an integer multiple of the number of cells
+ specified in its parent node (GPIO controller node).
+Only one of the following properties scanned in the order shown below.
+This means that when multiple properties are present they will be searched
+in the order presented below and the first match is taken as the intended
+configuration.
+- input: A property specifying to set the GPIO direction as input.
+- output-low A property specifying to set the GPIO direction as output with
+ the value low.
+- output-high A property specifying to set the GPIO direction as output with
+ the value high.
+
+Optional properties:
+- line-name: The GPIO label name. If not present the node name is used.
+
+Example of two SOC GPIO banks defined as gpio-controller nodes:
+
+ qe_pio_a: gpio-controller@1400 {
+ compatible = "fsl,qe-pario-bank-a", "fsl,qe-pario-bank";
+ reg = <0x1400 0x18>;
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ line_b-hog {
+ gpio-hog;
+ gpios = <6 0>;
+ output-low;
+ line-name = "foo-bar-gpio";
+ };
+ };
+
+ qe_pio_e: gpio-controller@1460 {
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1460 0x18>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+2.1) gpio- and pin-controller interaction
+-----------------------------------------
+
+Some or all of the GPIOs provided by a GPIO controller may be routed to pins
+on the package via a pin controller. This allows muxing those pins between
+GPIO and other functions. It is a fairly common practice among silicon
+engineers.
+
+2.2) Ordinary (numerical) GPIO ranges
+-------------------------------------
+
+It is useful to represent which GPIOs correspond to which pins on which pin
+controllers. The gpio-ranges property described below represents this with
+a discrete set of ranges mapping pins from the pin controller local number space
+to pins in the GPIO controller local number space.
+
+The format is: <[pin controller phandle], [GPIO controller offset],
+ [pin controller offset], [number of pins]>;
+
+The GPIO controller offset pertains to the GPIO controller node containing the
+range definition.
+
+The pin controller node referenced by the phandle must conform to the bindings
+described in pinctrl/pinctrl-bindings.txt.
+
+Each offset runs from 0 to N. It is perfectly fine to pile any number of
+ranges with just one pin-to-GPIO line mapping if the ranges are concocted, but
+in practice these ranges are often lumped in discrete sets.
+
+Example:
+
+ gpio-ranges = <&foo 0 20 10>, <&bar 10 50 20>;
+
+This means:
+- pins 20..29 on pin controller "foo" is mapped to GPIO line 0..9 and
+- pins 50..69 on pin controller "bar" is mapped to GPIO line 10..29
+
+
+Verbose example:
+
+ qe_pio_e: gpio-controller@1460 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1460 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 0 20 10>, <&pinctrl2 10 50 20>;
+ };
+
+Here, a single GPIO controller has GPIOs 0..9 routed to pin controller
+pinctrl1's pins 20..29, and GPIOs 10..29 routed to pin controller pinctrl2's
+pins 50..69.
+
+
+2.3) GPIO ranges from named pin groups
+--------------------------------------
+
+It is also possible to use pin groups for gpio ranges when pin groups are the
+easiest and most convenient mapping.
+
+Both both <pinctrl-base> and <count> must set to 0 when using named pin groups
+names.
+
+The property gpio-ranges-group-names must contain exactly one string for each
+range.
+
+Elements of gpio-ranges-group-names must contain the name of a pin group
+defined in the respective pin controller. The number of pins/GPIO lines in the
+range is the number of pins in that pin group. The number of pins of that
+group is defined int the implementation and not in the device tree.
+
+If numerical and named pin groups are mixed, the string corresponding to a
+numerical pin range in gpio-ranges-group-names must be empty.
+
+Example:
+
+ gpio_pio_i: gpio-controller@14b0 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1480 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 0 20 10>,
+ <&pinctrl2 10 0 0>,
+ <&pinctrl1 15 0 10>,
+ <&pinctrl2 25 0 0>;
+ gpio-ranges-group-names = "",
+ "foo",
+ "",
+ "bar";
+ };
+
+Here, three GPIO ranges are defined referring to two pin controllers.
+
+pinctrl1 GPIO ranges are defined using pin numbers whereas the GPIO ranges
+in pinctrl2 are defined using the pin groups named "foo" and "bar".
+
+Previous versions of this binding required all pin controller nodes that
+were referenced by any gpio-ranges property to contain a property named
+#gpio-range-cells with value <3>. This requirement is now deprecated.
+However, that property may still exist in older device trees for
+compatibility reasons, and would still be required even in new device
+trees that need to be compatible with older software.

+description: |
+ The IP core used inside these SoCs has 3 banks of 32 GPIOs each.
+ The registers of all the banks are interwoven inside one single IO range.
+ We load one GPIO controller instance per bank. Also the GPIO controller can receive
+ interrupts on any of the GPIOs, either edge or level. It then interrupts the CPU
+ using GIC INT12.

+title: NVIDIA Tegra GPIO Controller (Tegra186 and later)
+
+maintainers:
+ - Thierry Reding <thierry.reding@gmail.com>
+ - Jon Hunter <jonathanh@nvidia.com>
+
+description: |
+ Tegra186 contains two GPIO controllers; a main controller and an "AON"
+ controller. This binding document applies to both controllers. The register
+ layouts for the controllers share many similarities, but also some
+ significant differences. Hence, this document describes closely related but
+ different bindings and compatible values.
+
+ The Tegra186 GPIO controller allows software to set the IO direction of,
+ and read/write the value of, numerous GPIO signals. Routing of GPIO signals
+ to package balls is under the control of a separate pin controller hardware
+ block. Two major sets of registers exist:
+
+ a) Security registers, which allow configuration of allowed access to the
+ GPIO register set. These registers exist in a single contiguous block
+ of physical address space. The size of this block, and the security
+ features available, varies between the different GPIO controllers.
+
+ Access to this set of registers is not necessary in all circumstances.
+ Code that wishes to configure access to the GPIO registers needs access
+ to these registers to do so. Code which simply wishes to read or write
+ GPIO data does not need access to these registers.
+
+ b) GPIO registers, which allow manipulation of the GPIO signals. In some
+ GPIO controllers, these registers are exposed via multiple "physical
+ aliases" in address space, each of which access the same underlying
+ state. See the hardware documentation for rationale. Any particular
+ GPIO client is expected to access just one of these physical aliases.
+
+ Tegra HW documentation describes a unified naming convention for all GPIOs
+ implemented by the SoC. Each GPIO is assigned to a port, and a port may
+ control a number of GPIOs. Thus, each GPIO is named according to an
+ alphabetical port name and an integer GPIO name within the port. For
+ example, GPIO_PA0, GPIO_PN6, or GPIO_PCC3.
+
+ The number of ports implemented by each GPIO controller varies. The number
+ of implemented GPIOs within each port varies. GPIO registers within a
+ controller are grouped and laid out according to the port they affect.
+
+ The mapping from port name to the GPIO controller that implements that
+ port, and the mapping from port name to register offset within a
+ controller, are both extremely non-linear. The header file
+ <dt-bindings/gpio/tegra186-gpio.h> describes the port-level mapping. In
+ that file, the naming convention for ports matches the HW documentation.
+ The values chosen for the names are alphabetically sorted within a
+ particular controller. Drivers need to map between the DT GPIO IDs and HW
+ register offsets using a lookup table.
+
+ Each GPIO controller can generate a number of interrupt signals. Each
+ signal represents the aggregate status for all GPIOs within a set of
+ ports. Thus, the number of interrupt signals generated by a controller
+ varies as a rough function of the number of ports it implements. Note
+ that the HW documentation refers to both the overall controller HW
+ module and the sets-of-ports as "controllers".
+
+ Each GPIO controller in fact generates multiple interrupts signals for
+ each set of ports. Each GPIO may be configured to feed into a specific
+ one of the interrupt signals generated by a set-of-ports. The intent is
+ for each generated signal to be routed to a different CPU, thus allowing
+ different CPUs to each handle subsets of the interrupts within a port.
+ The status of each of these per-port-set signals is reported via a
+ separate register. Thus, a driver needs to know which status register to
+ observe. This binding currently defines no configuration mechanism for
+ this. By default, drivers should use register
+ GPIO_${port}_INTERRUPT_STATUS_G1_0. Future revisions to the binding could
+ define a property to configure this.

+description:
+ The PCF857x-compatible chips have "quasi-bidirectional" I/O lines that can be
+ driven high by a pull-up current source or driven low to ground. This
+ combines the direction and output level into a single bit per line, which
+ can't be read back. We can't actually know at initialization time whether a
+ line is configured (a) as output and driving the signal low/high, or (b) as
+ input and reporting a low/high value, without knowing the last value written
+ since the chip came out of reset (if any). The only reliable solution for
+ setting up line direction is thus to do it explicitly.

+Raspberry Pi GPIO expander
+
+The Raspberry Pi 3 GPIO expander is controlled by the VC4 firmware. The
+firmware exposes a mailbox interface that allows the ARM core to control the
+GPIO lines on the expander.
+
+The Raspberry Pi GPIO expander node must be a child node of the Raspberry Pi
+firmware node.
+
+Required properties:
+
+- compatible : Should be "raspberrypi,firmware-gpio"
+- gpio-controller : Marks the device node as a gpio controller
+- #gpio-cells : Should be two. The first cell is the pin number, and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+
+Example:

+firmware: firmware-rpi {

+ mboxes = <&mailbox>;
+
+ expgpio: gpio {

+description: |
+ Realtek's GPIO controller on their MIPS switch SoCs (Otto platform) consists
+ of two banks of 32 GPIOs. These GPIOs can generate edge-triggered interrupts.
+ Each bank's interrupts are cascased into one interrupt line on the parent

+ This binding allows defining a single bank in the devicetree. The interrupt
+ controller is not supported on the fallback compatible name, which only

+description:
+ The Rockchip RK3328 General Register File (GRF) outputs only the
+ GPIO_MUTE pin, originally for codec mute control, but it can also be used
+ for general purpose. It is manipulated by the GRF_SOC_CON10 register.
+ If needed in the future support for the HDMI pins can also be added.
+ The GPIO node should be declared as the child of the GRF node.

+GPIO controller on CE4100 / Sodaville SoCs
+==========================================
+
+The bindings for CE4100's GPIO controller match the generic description
+which is covered by the gpio.txt file in this folder.
+
+The only additional property is the intel,muxctl property which holds the
+value which is written into the MUXCNTL register.
+
+There is no compatible property for now because the driver is probed via
+PCI id (vendor 0x8086 device 0x2e67).
+
+The interrupt specifier consists of two cells encoded as follows:
+ - <1st cell>: The interrupt-number that identifies the interrupt source.
+ - <2nd cell>: The level-sense information, encoded as follows:
+ 4 - active high level-sensitive
+ 8 - active low level-sensitive
+
+Example of the GPIO device and one user:
+
+ pcigpio: gpio@b,1 {
+ /* two cells for GPIO and interrupt */
+ #gpio-cells = <2>;
+ #interrupt-cells = <2>;

+=== ST Microelectronics SPEAr SPI CS Driver ===
+
+SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
+Cell spi controller through its system registers, which otherwise remains under
+PL022 control. If chipselect remain under PL022 control then they would be
+released as soon as transfer is over and TxFIFO becomes empty. This is not
+desired by some of the device protocols above spi which expect (multiple)
+transfers without releasing their chipselects.
+
+Chipselects can be controlled by software by turning them as GPIOs. SPEAr
+provides another interface through system registers through which software can
+directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
+the control of this interface as gpio.
+
+Required properties:
+
+ * compatible: should be defined as "st,spear-spics-gpio"
+ * reg: mentioning address range of spics controller
+ * st-spics,peripcfg-reg: peripheral configuration register offset
+ * st-spics,sw-enable-bit: bit offset to enable sw control
+ * st-spics,cs-value-bit: bit offset to drive chipselect low or high
+ * st-spics,cs-enable-mask: chip select number bit mask
+ * st-spics,cs-enable-shift: chip select number program offset
+ * gpio-controller: Marks the device node as gpio controller
+ * #gpio-cells: should be 1 and will mention chip select number
+
+All the above bit offsets are within peripcfg register.
+
+Example:

+description: |
+ The EIC is the abbreviation of external interrupt controller, which can
+ be used only in input mode. The Spreadtrum platform has 2 EIC controllers,
+ one is in digital chip, and another one is in PMIC. The digital chip EIC
+ controller contains 4 sub-modules, i.e. EIC-debounce, EIC-latch, EIC-async and
+ EIC-sync. But the PMIC EIC controller contains only one EIC-debounce sub-
+ module.
+
+ The EIC-debounce sub-module provides up to 8 source input signal
+ connections. A debounce mechanism is used to capture the input signals'
+ stable status (millisecond resolution) and a single-trigger mechanism
+ is introduced into this sub-module to enhance the input event detection
+ reliability. In addition, this sub-module's clock can be shut off
+ automatically to reduce power dissipation. Moreover the debounce range
+ is from 1ms to 4s with a step size of 1ms. The input signal will be
+ ignored if it is asserted for less than 1 ms.
+
+ The EIC-latch sub-module is used to latch some special power down signals
+ and generate interrupts, since the EIC-latch does not depend on the APB
+ clock to capture signals.
+
+ The EIC-async sub-module uses a 32kHz clock to capture the short signals
+ (microsecond resolution) to generate interrupts by level or edge trigger.
+
+ The EIC-sync is similar with GPIO's input function, which is a synchronized
+ signal input register. It can generate interrupts by level or edge trigger
+ when detecting input signals.

+Required properties:
+- compatible: "nvidia,<gpu>"
+ Currently recognized values:
+ - nvidia,gk20a
+ - nvidia,gm20b
+ - nvidia,gp10b
+ - nvidia,gv11b
+- reg: Physical base address and length of the controller's registers.
+ Must contain two entries:
+ - first entry for bar0
+ - second entry for bar1
+- interrupts: Must contain an entry for each entry in interrupt-names.
+ See ../interrupt-controller/interrupts.txt for details.
+- interrupt-names: Must include the following entries:
+ - stall
+ - nonstall
+- vdd-supply: regulator for supply voltage. Only required for GPUs not using
+ power domains.
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - gpu
+ - pwr
+If the compatible string is "nvidia,gm20b", then the following clock
+is also required:
+ - ref
+If the compatible string is "nvidia,gv11b", then the following clock is also
+required:
+ - fuse
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - gpu
+- power-domains: GPUs that make use of power domains can define this property
+ instead of vdd-supply. Currently "nvidia,gp10b" makes use of this.
+
+Optional properties:

+OMAP SSI controller bindings
+
+OMAP3's Synchronous Serial Interface (SSI) controller implements a
+legacy variant of MIPI's High Speed Synchronous Serial Interface (HSI),
+while the controller found inside OMAP4 is supposed to be fully compliant
+with the HSI standard.
+
+Required properties:
+- compatible: Should include "ti,omap3-ssi" or "ti,omap4-hsi"
+- reg-names: Contains the values "sys" and "gdd" (in this order).
+- reg: Contains a matching register specifier for each entry
+ in reg-names.
+- interrupt-names: Contains the value "gdd_mpu".
+- interrupts: Contains matching interrupt information for each entry
+ in interrupt-names.
+- ranges: Represents the bus address mapping between the main
+ controller node and the child nodes below.
+- clock-names: Must include the following entries:
+ "ssi_ssr_fck": The OMAP clock of that name
+ "ssi_sst_fck": The OMAP clock of that name
+ "ssi_ick": The OMAP clock of that name
+- clocks: Contains a matching clock specifier for each entry in
+ clock-names.
+- #address-cells: Should be set to <1>
+- #size-cells: Should be set to <1>
+
+Each port is represented as a sub-node of the ti,omap3-ssi device.
+
+Required Port sub-node properties:
+- compatible: Should be set to the following value
+ ti,omap3-ssi-port (applicable to OMAP34xx devices)
+ ti,omap4-hsi-port (applicable to OMAP44xx devices)
+- reg-names: Contains the values "tx" and "rx" (in this order).
+- reg: Contains a matching register specifier for each entry
+ in reg-names.
+- interrupts: Should contain interrupt specifiers for mpu interrupts
+ 0 and 1 (in this order).
+- ti,ssi-cawake-gpio: Defines which GPIO pin is used to signify CAWAKE
+ events for the port. This is an optional board-specific
+ property. If it's missing the port will not be
+ enabled.
+
+Optional properties:
+- ti,hwmods: Shall contain TI interconnect module name if needed
+ by the SoC
+

+Generic hwlock bindings
+=======================
+
+Generic bindings that are common to all the hwlock platform specific driver
+implementations.
+
+Please also look through the individual platform specific hwlock binding
+documentations for identifying any additional properties specific to that
+platform.
+
+hwlock providers:
+=================
+
+Required properties:
+- #hwlock-cells: Specifies the number of cells needed to represent a
+ specific lock.
+
+hwlock users:
+=============
+
+Consumers that require specific hwlock(s) should specify them using the
+property "hwlocks", and an optional "hwlock-names" property.
+
+Required properties:
+- hwlocks: List of phandle to a hwlock provider node and an
+ associated hwlock args specifier as indicated by
+ #hwlock-cells. The list can have just a single hwlock
+ or multiple hwlocks, with each hwlock represented by
+ a phandle and a corresponding args specifier.
+
+Optional properties:
+- hwlock-names: List of hwlock name strings defined in the same order
+ as the hwlocks, with one name per hwlock. Consumers can
+ use the hwlock-names to match and get a specific hwlock.
+
+
+1. Example of a node using a single specific hwlock:
+
+The following example has a node requesting a hwlock in the bank defined by
+the node hwlock1. hwlock1 is a hwlock provider with an argument specifier
+of length 1.
+
+ node {
+ ...
+ hwlocks = <&hwlock1 2>;
+ ...
+ };
+
+2. Example of a node using multiple specific hwlocks:
+
+The following example has a node requesting two hwlocks, a hwlock within
+the hwlock device node 'hwlock1' with #hwlock-cells value of 1, and another
+hwlock within the hwlock device node 'hwlock2' with #hwlock-cells value of 2.
+
+ node {
+ ...
+ hwlocks = <&hwlock1 2>, <&hwlock2 0 3>;
+ ...
+ };

+SPRD Hardware Spinlock Device Binding
+-------------------------------------
+
+Required properties :
+- compatible : should be "sprd,hwspinlock-r3p0".
+- reg : the register address of hwspinlock.
+- #hwlock-cells : hwlock users only use the hwlock id to represent a specific
+ hwlock, so the number of cells should be <1> here.
+- clock-names : Must contain "enable".
+- clocks : Must contain a phandle entry for the clock in clock-names, see the
+ common clock bindings.
+
+Please look at the generic hwlock binding for usage information for consumers,
+"Documentation/devicetree/bindings/hwlock/hwlock.txt"

+Required properties:

+Optional properties:
+- gpios: Specifies the pins that map to bits in the control value,
+ ordered MSB-->LSB.
+- gpio-fan,speed-map: A mapping of possible fan RPM speeds and the
+ control value that should be set to achieve them. This array
+ must have the RPM values in ascending order.
+- alarm-gpios: This pin going active indicates something is wrong with

+- #cooling-cells: If used as a cooling device, must be <2>
+ Also see:
+ Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml
+ min and max states are derived from the speed-map of the fan.

+
+maintainers:

+
+description: |
+ A Moortec PVT (Process, Voltage, Temperature) monitoring logic design can
+ include many different units.
+ Such a design will usually consists of several Moortec's embedded analog IPs,
+ and a single Moortec controller (mr75203) to configure and control the IPs.
+
+ Some of the Moortec's analog hard IPs that can be used in a design:
+ *) Temperature Sensor (TS) - used to monitor core temperature (e.g. mr74137).
+ *) Voltage Monitor (VM) - used to monitor voltage levels (e.g. mr74138).
+ *) Process Detector (PD) - used to assess silicon speed (e.g. mr74139).
+ *) Delay Chain - ring oscillator connected to the PD, used to measure IO
+ based transistors (e.g. mr76008 ring oscillator at 1.1V, mr76007 ring
+ oscillator at 1.8V).
+ *) Pre Scaler - provides divide-by-X scaling of input voltage, which can then
+ be presented for VM for measurement within its range (e.g. mr76006 -
+ divide by 2 pre-scaler).
+
+ TS, VM & PD also include a digital interface, which consists of configuration
+ inputs and measurement outputs.
+
+ Some of the units have number of series, each series can have slightly
+ different characteristics.
+
+ The mr75203 binding describes configuration for the controller unit, but also
+ for some of the analog IPs.

+title: NTC thermistor temperature sensors

+
+description: |
+ Thermistors with negative temperature coefficient (NTC) are resistors that
+ vary in resistance in an often non-linear way in relation to temperature.
+ The negative temperature coefficient means that the resistance decreases
+ as the temperature rises. Since the relationship between resistance and
+ temperature is non-linear, software drivers most often need to use a look
+ up table and interpolation to get from resistance to temperature.
+
+ When used in practice, a thermistor is often connected between ground, a
+ pull-up resistor or/and a pull-down resistor and a fixed voltage like this:
+
+ + e.g. 5V = pull-up voltage (puv)
+ |
+ +-+
+ | |
+ | | Pull-up resistor
+ | | (puo)
+ +-+
+ |-------------------------o
+ +-+ | ^
+ | |/ |
+ | / |
+ |/| Thermistor | Measured voltage (mv)
+ / | | "connected ground"
+ /| | |
+ +-+ |
+ |-------------------------o
+ +-+ ^
+ | | |
+ | | Pull-down resistor | Measured voltage (mv)
+ | | (pdo) | "connected positive"
+ +-+ |
+ | |
+ | v
+ + GND GND
+
+ The arrangements of where we measure the voltage over the thermistor are
+ called "connected ground" and "connected positive" and shall be understood as
+ the cases when either pull-up or pull-down resistance is zero.
+
+ If the pull-up resistance is 0 one end of the thermistor is connected to the
+ positive voltage and we get the thermistor on top of a pull-down resistor
+ and we take the measure between the thermistor and the pull-down resistor.
+
+ Conversely if the pull-down resistance is zero, one end of the thermistor is
+ connected to ground and we get the thermistor under the pull-up resistor
+ and we take the measure between the pull-up resistor and the thermistor.
+
+ We can use both pull-up and pull-down resistors at the same time, and then
+ the figure illustrates where the voltage will be measured for the "connected
+ ground" and "connected positive" cases.

+ current shunt monitor. These system monitors have the capability of measuring
+ remote temperatures, on-chip temperatures, and system voltage/power/current
+ consumption.

+title: GPIO-based I2C Arbitration Using a Challenge & Response Mechanism
+
+maintainers:
+ - Doug Anderson <dianders@chromium.org>
+ - Peter Rosin <peda@axentia.se>
+
+description: |
+ This uses GPIO lines and a challenge & response mechanism to arbitrate who is
+ the master of an I2C bus in a multimaster situation.
+
+ In many cases using GPIOs to arbitrate is not needed and a design can use the
+ standard I2C multi-master rules. Using GPIOs is generally useful in the case
+ where there is a device on the bus that has errata and/or bugs that makes
+ standard multimaster mode not feasible.
+
+ Note that this scheme works well enough but has some downsides:
+ * It is nonstandard (not using standard I2C multimaster)
+ * Having two masters on a bus in general makes it relatively hard to debug
+ problems (hard to tell if i2c issues were caused by one master, another,
+ or some device on the bus).
+
+ Algorithm:
+ All masters on the bus have a 'bus claim' line which is an output that the
+ others can see. These are all active low with pull-ups enabled. We'll
+ describe these lines as:
+ * OUR_CLAIM: output from us signaling to other hosts that we want the bus
+ * THEIR_CLAIMS: output from others signaling that they want the bus
+
+ The basic algorithm is to assert your line when you want the bus, then make
+ sure that the other side doesn't want it also. A detailed explanation is
+ best done with an example.
+
+ Let's say we want to claim the bus. We:
+ 1. Assert OUR_CLAIM.
+ 2. Waits a little bit for the other sides to notice (slew time, say 10
+ microseconds).
+ 3. Check THEIR_CLAIMS. If none are asserted then the we have the bus and we
+ are done.
+ 4. Otherwise, wait for a few milliseconds and see if THEIR_CLAIMS are released.
+ 5. If not, back off, release the claim and wait for a few more milliseconds.
+ 6. Go back to 1 (until retry time has expired).

+description:
+ An I2C Address Translator (ATR) is a device with an I2C slave parent
+ ("upstream") port and N I2C master child ("downstream") ports, and
+ forwards transactions from upstream to the appropriate downstream port
+ with a modified slave address. The address used on the parent bus is
+ called the "alias" and is (potentially) different from the physical
+ slave address of the child bus. Address translation is done by the
+ hardware.
+
+properties:
+ i2c-alias-pool:
+ $ref: /schemas/types.yaml#/definitions/uint32-array
+ description:
+ I2C alias pool is a pool of I2C addresses on the main I2C bus that can be
+ used to access the remote peripherals on the serializer's I2C bus. The
+ addresses must be available, not used by any other peripheral. Each
+ remote peripheral is assigned an alias from the pool, and transactions to
+ that address will be forwarded to the remote peripheral, with the address
+ translated to the remote peripheral's real address. This property is not
+ needed if there are no I2C addressable remote peripherals.

+Pinctrl-based I2C Bus DeMux
+
+This binding describes an I2C bus demultiplexer that uses pin multiplexing to
+route the I2C signals, and represents the pin multiplexing configuration using
+the pinctrl device tree bindings. This may be used to select one I2C IP core at
+runtime which may have a better feature set for a given task than another I2C
+IP core on the SoC. The most simple example is to fall back to GPIO bitbanging
+if your current runtime configuration hits an errata of the internal IP core.
+
+ +-------------------------------+

+ | |I2C IP Core1|--\ | +-----+ +-----+

+ | |Pinctrl|--|------+--------+
+ | +------------+ +-------+ |
+ | |I2C IP Core2|--/ |
+ | +------------+ |
+ | |
+ +-------------------------------+
+
+Required properties:
+- compatible: "i2c-demux-pinctrl"
+- i2c-parent: List of phandles of I2C masters available for selection. The first
+ one will be used as default.
+- i2c-bus-name: The name of this bus. Also needed as pinctrl-name for the I2C
+ parents.
+
+Furthermore, I2C mux properties and child nodes. See i2c-mux.yaml in this
+directory.
+
+Example:
+
+Here is a snipplet for a bus to be demuxed. It contains various i2c clients for
+HDMI, so the bus is named "i2c-hdmi":
+
+ i2chdmi: i2c@8 {
+
+ compatible = "i2c-demux-pinctrl";
+ i2c-parent = <&gpioi2c>, <&iic2>, <&i2c2>;
+ i2c-bus-name = "i2c-hdmi";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ak4643: sound-codec@12 {
+ compatible = "asahi-kasei,ak4643";
+
+ #sound-dai-cells = <0>;
+ reg = <0x12>;
+ };
+
+ composite-in@20 {
+ compatible = "adi,adv7180";
+ reg = <0x20>;
+ remote = <&vin1>;
+
+ port {
+ adv7180: endpoint {
+ bus-width = <8>;
+ remote-endpoint = <&vin1ep0>;
+ };
+ };
+ };
+
+ hdmi@39 {
+ compatible = "adi,adv7511w";
+ reg = <0x39>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <15 IRQ_TYPE_LEVEL_LOW>;
+
+ adi,input-depth = <8>;
+ adi,input-colorspace = "rgb";
+ adi,input-clock = "1x";
+ adi,input-style = <1>;
+ adi,input-justification = "evenly";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ adv7511_in: endpoint {
+ remote-endpoint = <&du_out_lvds0>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+ adv7511_out: endpoint {
+ remote-endpoint = <&hdmi_con>;
+ };
+ };
+ };
+ };
+ };
+
+And for clarification, here are the snipplets for the i2c-parents:
+
+ gpioi2c: i2c@9 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "i2c-gpio";
+ gpios = <&gpio5 6 GPIO_ACTIVE_HIGH /* sda */
+ &gpio5 5 GPIO_ACTIVE_HIGH /* scl */
+ >;
+ i2c-gpio,delay-us = <5>;
+ };
+
+...
+
+&i2c2 {
+ pinctrl-0 = <&i2c2_pins>;
+ pinctrl-names = "i2c-hdmi";
+
+ clock-frequency = <100000>;
+};
+

+
+&iic2 {
+ pinctrl-0 = <&iic2_pins>;
+ pinctrl-names = "i2c-hdmi";
+
+ clock-frequency = <100000>;
+};
+
+Please note:
+
+- pinctrl properties for the parent I2C controllers need a pinctrl state
+ with the same name as i2c-bus-name, not "default"!
+
+- the i2c masters must have their status "disabled". This driver will
+ enable them at runtime when needed.

+Register-based I2C Bus Mux
+
+This binding describes an I2C bus multiplexer that uses a single register
+to route the I2C signals.
+
+Required properties:
+- compatible: i2c-mux-reg
+- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
+ port is connected to.
+* Standard I2C mux properties. See i2c-mux.yaml in this directory.
+* I2C child bus nodes. See i2c-mux.yaml in this directory.
+
+Optional properties:
+- reg: this pair of <offset size> specifies the register to control the mux.
+ The <offset size> depends on its parent node. It can be any memory-mapped
+ address. The size must be either 1, 2, or 4 bytes. If reg is omitted, the
+ resource of this device will be used.
+- little-endian: The existence indicates the register is in little endian.
+- big-endian: The existence indicates the register is in big endian.
+ If both little-endian and big-endian are omitted, the endianness of the
+ CPU will be used.
+- write-only: The existence indicates the register is write-only.
+- idle-state: value to set the muxer to when idle. When no value is
+ given, it defaults to the last value used.
+
+Whenever an access is made to a device on a child bus, the value set
+in the relevant node's reg property will be output to the register.
+
+If an idle state is defined, using the idle-state (optional) property,
+whenever an access is not being made to a device on a child bus, the
+register will be set according to the idle value.
+
+If an idle state is not defined, the most recently used value will be
+left programmed into the register.
+
+Example of a mux on PCIe card, the host is a powerpc SoC (big endian):
+
+ i2c-mux {
+ /* the <offset size> depends on the address translation
+ * of the parent device. If omitted, device resource
+ * will be used instead. The size is to determine

+Device-tree bindings for I2C OPAL driver
+----------------------------------------
+
+Most of the device node and properties layout is specific to the firmware and
+used by the firmware itself for configuring the port. From the linux
+perspective, the properties of use are "ibm,port-name" and "ibm,opal-id".
+
+Required properties:
+
+- reg: Port-id within a given master
+- compatible: must be "ibm,opal-i2c"
+- ibm,opal-id: Refers to a specific bus and used to identify it when calling
+ the relevant OPAL functions.
+- bus-frequency: Operating frequency of the i2c bus (in HZ). Informational for
+ linux, used by the FW though.
+
+Optional properties:
+- ibm,port-name: Firmware provides this name that uniquely identifies the i2c
+ port.
+
+The node contains a number of other properties that are used by the FW itself
+and depend on the specific hardware implementation. The example below depicts
+a P8 on-chip bus.

+* NXP PCA PCA9564/PCA9665 I2C controller
+
+The PCA9564/PCA9665 serves as an interface between most standard
+parallel-bus microcontrollers/microprocessors and the serial I2C-bus
+and allows the parallel bus system to communicate bi-directionally
+with the I2C-bus.
+
+Required properties :
+
+ - reg : Offset and length of the register set for the device
+ - compatible : one of "nxp,pca9564" or "nxp,pca9665"
+
+Optional properties
+ - interrupts : the interrupt number
+ - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line
+ is active low, it should be marked GPIO_ACTIVE_LOW.
+ - clock-frequency : I2C bus frequency.
+
+Example:
+ i2c0: i2c@80000 {
+ compatible = "nxp,pca9564";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x80000 0x4>;
+ reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;

+CE4100 I2C
+----------
+
+CE4100 has one PCI device which is described as the I2C-Controller. This
+PCI device has three PCI-bars, each bar contains a complete I2C
+controller. So we have a total of three independent I2C-Controllers
+which share only an interrupt line.
+The driver is probed via the PCI-ID and is gathering the information of
+attached devices from the devices tree.
+Grant Likely recommended to use the ranges property to map the PCI-Bar
+number to its physical address and to use this to find the child nodes
+of the specific I2C controller. This were his exact words:
+
+ Here's where the magic happens. Each entry in
+ ranges describes how the parent pci address space
+ (middle group of 3) is translated to the local
+ address space (first group of 2) and the size of
+ each range (last cell). In this particular case,
+ the first cell of the local address is chosen to be
+ 1:1 mapped to the BARs, and the second is the
+ offset from be base of the BAR (which would be
+ non-zero if you had 2 or more devices mapped off
+ the same BAR)
+
+ ranges allows the address mapping to be described
+ in a way that the OS can interpret without
+ requiring custom device driver code.
+
+This is an example which is used on FalconFalls:
+------------------------------------------------
+ i2c-controller@b,2 {
+ #address-cells = <2>;
+ #size-cells = <1>;

+ "pciclass,ff0000",
+ "pciclass,ff00";
+
+ reg = <0x15a00 0x0 0x0 0x0 0x0>;
+ interrupts = <16 1>;
+
+ /* as described by Grant, the first number in the group of
+ * three is the bar number followed by the 64bit bar address
+ * followed by size of the mapping. The bar address
+ * requires also a valid translation in parents ranges
+ * property.
+ */

+Generic device tree bindings for I2C busses
+===========================================
+
+This document describes generic bindings which can be used to describe I2C
+busses and their child devices in a device tree.
+
+Required properties (per bus)
+-----------------------------
+
+- #address-cells - should be <1>. Read more about addresses below.
+- #size-cells - should be <0>.
+- compatible - name of I2C bus controller
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+
+The cells properties above define that an address of children of an I2C bus
+are described by a single value.
+
+Optional properties (per bus)
+-----------------------------
+
+These properties may not be supported by all drivers. However, if a driver
+wants to support one of the below features, it should adapt these bindings.
+
+- clock-frequency
+ frequency of bus clock in Hz.
+
+- i2c-bus
+ For I2C adapters that have child nodes that are a mixture of both I2C
+ devices and non-I2C devices, the 'i2c-bus' subnode can be used for
+ populating I2C devices. If the 'i2c-bus' subnode is present, only
+ subnodes of this will be considered as I2C slaves. The properties,
+ '#address-cells' and '#size-cells' must be defined under this subnode
+ if present.
+
+- i2c-scl-falling-time-ns
+ Number of nanoseconds the SCL signal takes to fall; t(f) in the I2C
+ specification.
+
+- i2c-scl-internal-delay-ns
+ Number of nanoseconds the IP core additionally needs to setup SCL.
+
+- i2c-scl-rising-time-ns
+ Number of nanoseconds the SCL signal takes to rise; t(r) in the I2C
+ specification.
+
+- i2c-sda-falling-time-ns
+ Number of nanoseconds the SDA signal takes to fall; t(f) in the I2C
+ specification.
+
+- i2c-analog-filter
+ Enable analog filter for i2c lines.
+
+- i2c-digital-filter
+ Enable digital filter for i2c lines.
+
+- i2c-digital-filter-width-ns
+ Width of spikes which can be filtered by digital filter
+ (i2c-digital-filter). This width is specified in nanoseconds.
+
+- i2c-analog-filter-cutoff-frequency
+ Frequency that the analog filter (i2c-analog-filter) uses to distinguish
+ which signal to filter. Signal with higher frequency than specified will
+ be filtered out. Only lower frequency will pass (this is applicable to
+ a low-pass analog filter). Typical value should be above the normal
+ i2c bus clock frequency (clock-frequency).
+ Specified in Hz.
+
+- multi-master
+ states that there is another master active on this bus. The OS can use
+ this information to adapt power management to keep the arbitration awake
+ all the time, for example. Can not be combined with 'single-master'.
+
+- pinctrl
+ add extra pinctrl to configure SCL/SDA pins to GPIO function for bus
+ recovery, call it "gpio" or "recovery" (deprecated) state
+
+- scl-gpios
+ specify the gpio related to SCL pin. Used for GPIO bus recovery.
+
+- sda-gpios
+ specify the gpio related to SDA pin. Optional for GPIO bus recovery.
+
+- single-master
+ states that there is no other master active on this bus. The OS can use
+ this information to detect a stalled bus more reliably, for example.
+ Can not be combined with 'multi-master'.
+
+- smbus
+ states that additional SMBus restrictions and features apply to this bus.
+ An example of feature is SMBusHostNotify. Examples of restrictions are
+ more reserved addresses and timeout definitions.
+
+- smbus-alert
+ states that the optional SMBus-Alert feature apply to this bus.
+
+- mctp-controller
+ indicates that the system is accessible via this bus as an endpoint for
+ MCTP over I2C transport.
+
+Required properties (per child device)
+--------------------------------------
+
+- compatible
+ name of I2C slave device
+
+- reg
+ One or many I2C slave addresses. These are usually a 7 bit addresses.
+ However, flags can be attached to an address. I2C_TEN_BIT_ADDRESS is
+ used to mark a 10 bit address. It is needed to avoid the ambiguity
+ between e.g. a 7 bit address of 0x50 and a 10 bit address of 0x050
+ which, in theory, can be on the same bus.
+ Another flag is I2C_OWN_SLAVE_ADDRESS to mark addresses on which we
+ listen to be devices ourselves.
+
+Optional properties (per child device)
+--------------------------------------
+
+These properties may not be supported by all drivers. However, if a driver
+wants to support one of the below features, it should adapt these bindings.
+
+- host-notify
+ device uses SMBus host notify protocol instead of interrupt line.
+
+- interrupts
+ interrupts used by the device.
+
+- interrupt-names
+ "irq", "wakeup" and "smbus_alert" names are recognized by I2C core,
+ other names are left to individual drivers.
+
+- reg-names
+ Names of map programmable addresses.
+ It can contain any map needing another address than default one.
+
+- wakeup-source
+ device can be used as a wakeup source.
+
+Binding may contain optional "interrupts" property, describing interrupts
+used by the device. I2C core will assign "irq" interrupt (or the very first
+interrupt if not using interrupt names) as primary interrupt for the slave.
+
+Alternatively, devices supporting SMBus Host Notify, and connected to
+adapters that support this feature, may use "host-notify" property. I2C
+core will create a virtual interrupt for Host Notify and assign it as
+primary interrupt for the slave.
+
+Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
+interrupt for the device. If "wakeup" interrupt name is not present in the
+binding, then primary interrupt will be used as wakeup interrupt.

+description: |
+ The ADXL367 is an ultralow power, 3-axis MEMS accelerometer.
+
+ The ADXL367 does not alias input signals by to achieve ultralow power
+ consumption, it samples the full bandwidth of the sensor at all
+ data rates. Measurement ranges of +-2g, +-4g, and +-8g are available,
+ with a resolution of 0.25mg/LSB on the +-2 g range.
+
+ In addition to its ultralow power consumption, the ADXL367
+ has many features to enable true system level power reduction.
+ It includes a deep multimode output FIFO, a built-in micropower
+ temperature sensor, and an internal ADC for synchronous conversion
+ of an additional analog input.

+LIS302 accelerometer devicetree bindings
+
+This device is matched via its bus drivers, and has a number of properties
+that apply in on the generic device (independent from the bus).
+
+
+Required properties for the SPI bindings:
+ - compatible: should be set to "st,lis3lv02d-spi"
+ - reg: the chipselect index
+ - spi-max-frequency: maximal bus speed, should be set to 1000000 unless
+ constrained by external circuitry
+ - interrupts: the interrupt generated by the device
+
+Required properties for the I2C bindings:
+ - compatible: should be set to "st,lis3lv02d"
+ - reg: i2c slave address
+ - Vdd-supply: The input supply for Vdd
+ - Vdd_IO-supply: The input supply for Vdd_IO
+
+
+Optional properties for all bus drivers:
+
+ - st,click-single-{x,y,z}: if present, tells the device to issue an
+ interrupt on single click events on the
+ x/y/z axis.
+ - st,click-double-{x,y,z}: if present, tells the device to issue an
+ interrupt on double click events on the
+ x/y/z axis.
+ - st,click-thresh-{x,y,z}: set the x/y/z axis threshold
+ - st,click-click-time-limit: click time limit, from 0 to 127.5msec
+ with step of 0.5 msec
+ - st,click-latency: click latency, from 0 to 255 msec with
+ step of 1 msec.
+ - st,click-window: click window, from 0 to 255 msec with
+ step of 1 msec.
+ - st,irq{1,2}-disable: disable IRQ 1/2
+ - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition
+ - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition
+ - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition
+ - st,irq{1,2}-click: raise IRQ 1/2 on click condition
+ - st,irq-open-drain: consider IRQ lines open-drain
+ - st,irq-active-low: make IRQ lines active low
+ - st,wu-duration-1: duration register for Free-Fall/Wake-Up
+ interrupt 1
+ - st,wu-duration-2: duration register for Free-Fall/Wake-Up
+ interrupt 2
+ - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit
+ - st,wakeup-threshold: set wakeup threshold
+ - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit for second wakeup
+ engine.
+ - st,wakeup2-threshold: set wakeup threshold for second wakeup
+ engine.
+ - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
+ highpass cut-off frequency
+ - st,hipass{1,2}-disable: disable highpass 1/2.
+ - st,default-rate=: set the default rate
+ - st,axis-{x,y,z}=: set the axis to map to the three coordinates.
+ Negative values can be used for inverted axis.
+ - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis
+ (used by self-test)
+
+

+description: |
+ STM32 ADC is a successive approximation analog-to-digital converter.
+ It has several multiplexed input channels. Conversions can be performed
+ in single, continuous, scan or discontinuous mode. Result of the ADC is
+ stored in a left-aligned or right-aligned 32-bit data register.
+ Conversions can be launched in software or using hardware triggers.
+
+ The analog watchdog feature allows the application to detect if the input
+ voltage goes beyond the user-defined, higher or lower thresholds.
+
+ Each STM32 ADC block can have up to 3 ADC instances.

+description: |
+ STM32 DFSDM ADC is a sigma delta analog-to-digital converter dedicated to
+ interface external sigma delta modulators to STM32 micro controllers.
+ It is mainly targeted for:
+ - Sigma delta modulators (motor control, metering...)
+ - PDM microphones (audio digital microphone)
+
+ It features up to 8 serial digital interfaces (SPI or Manchester) and
+ up to 4 filters on stm32h7 or 6 filters on stm32mp1.
+
+ Each child node matches with a filter instance.

+Xilinx XADC device driver
+
+This binding document describes the bindings for the Xilinx 7 Series XADC as well
+as the UltraScale/UltraScale+ System Monitor.
+
+The Xilinx XADC is an ADC that can be found in the Series 7 FPGAs from Xilinx.
+The XADC has a DRP interface for communication. Currently two different
+frontends for the DRP interface exist. One that is only available on the ZYNQ
+family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
+on all series 7 platforms and is a softmacro with a AXI interface. This binding
+document describes the bindings for both of them since the bindings are very
+similar.
+
+The Xilinx System Monitor is an ADC that is found in the UltraScale and
+UltraScale+ FPGAs from Xilinx. The System Monitor provides a DRP interface for
+communication. Xilinx provides a standard IP core that can be used to access the
+System Monitor through an AXI interface in the FPGA fabric. This IP core is
+called the Xilinx System Management Wizard. This document describes the bindings
+for this IP.
+
+Required properties:
+ - compatible: Should be one of
+ * "xlnx,zynq-xadc-1.00.a": When using the ZYNQ device
+ configuration interface to interface to the XADC hardmacro.
+ * "xlnx,axi-xadc-1.00.a": When using the axi-xadc pcore to
+ interface to the XADC hardmacro.
+ * "xlnx,system-management-wiz-1.3": When using the
+ Xilinx System Management Wizard fabric IP core to access the
+ UltraScale and UltraScale+ System Monitor.
+ - reg: Address and length of the register set for the device
+ - interrupts: Interrupt for the XADC control interface.
+ - clocks: When using the ZYNQ this must be the ZYNQ PCAP clock,
+ when using the axi-xadc or the axi-system-management-wizard this must be
+ the clock that provides the clock to the AXI bus interface of the core.
+
+Optional properties:
+ - xlnx,external-mux:
+ * "none": No external multiplexer is used, this is the default
+ if the property is omitted.
+ * "single": External multiplexer mode is used with one
+ multiplexer.
+ * "dual": External multiplexer mode is used with two
+ multiplexers for simultaneous sampling.
+ - xlnx,external-mux-channel: Configures which pair of pins is used to
+ sample data in external mux mode.
+ Valid values for single external multiplexer mode are:
+ 0: VP/VN
+ 1: VAUXP[0]/VAUXN[0]
+ 2: VAUXP[1]/VAUXN[1]
+ ...
+ 16: VAUXP[15]/VAUXN[15]
+ Valid values for dual external multiplexer mode are:
+ 1: VAUXP[0]/VAUXN[0] - VAUXP[8]/VAUXN[8]
+ 2: VAUXP[1]/VAUXN[1] - VAUXP[9]/VAUXN[9]
+ ...
+ 8: VAUXP[7]/VAUXN[7] - VAUXP[15]/VAUXN[15]
+
+ This property needs to be present if the device is configured for
+ external multiplexer mode (either single or dual). If the device is
+ not using external multiplexer mode the property is ignored.
+ - xnlx,channels: List of external channels that are connected to the ADC
+ Required properties:
+ * #address-cells: Should be 1.
+ * #size-cells: Should be 0.
+
+ The child nodes of this node represent the external channels which are
+ connected to the ADC. If the property is no present no external
+ channels will be assumed to be connected.
+
+ Each child node represents one channel and has the following
+ properties:
+ Required properties:
+ * reg: Pair of pins the channel is connected to.
+ 0: VP/VN
+ 1: VAUXP[0]/VAUXN[0]
+ 2: VAUXP[1]/VAUXN[1]
+ ...
+ 16: VAUXP[15]/VAUXN[15]
+ Note each channel number should only be used at most
+ once.
+ Optional properties:
+ * xlnx,bipolar: If set the channel is used in bipolar
+ mode.

+description: |
+ The AMS (Analog Monitoring System) includes an ADC as well as on-chip sensors
+ that can be used to sample external voltages and monitor on-die operating
+ conditions, such as temperature and supply voltage levels.
+ The AMS has two SYSMON blocks which are PL (Programmable Logic) SYSMON and
+ PS (Processing System) SYSMON.
+ All designs should have AMS registers, but PS and PL are optional. The
+ AMS controller can work with only PS, only PL and both PS and PL
+ configurations. Please specify registers according to your design. Devicetree
+ should always have AMS module property. Providing PS & PL module is optional.

+description: |
+ A temperature transducer is a device that converts a thermal quantity
+ into any other physical quantity. This binding applies to temperature to
+ voltage (like the LTC2997), and temperature to current (like the AD590)
+ linear transducers.
+ In both cases these are assumed to be connected to a voltage ADC.
+
+ When an io-channel measures the output voltage of a temperature analog front
+ end such as a temperature transducer, the interesting measurement is almost
+ always the corresponding temperature, not the voltage output. This binding
+ describes such a circuit.
+
+ The general transfer function here is (using SI units)
+ V(T) = Rsense * Isense(T)
+ T = (Isense(T) / alpha) + offset
+ T = 1 / (Rsense * alpha) * (V + offset * Rsense * alpha)
+
+ When using a temperature to voltage transducer, Rsense is set to 1.
+
+ The following circuits show a temperature to current and a temperature to
+ voltage transducer that can be used with this binding.

+ aperture. This value gives an indication to userspace for which
+ sensor readings this is the case.

+
+ Programmable Power Control (PPC)
+ In this mode, the VDPC+ voltage is user-programmable to a fixed level

+For discussion. Unclear are:

+
+====
+
+
+Mounting matrix
+
+The mounting matrix is a device tree property used to orient any device
+that produce three-dimensional data in relation to the world where it is
+deployed.
+
+The purpose of the mounting matrix is to translate the sensor frame of
+reference into the device frame of reference using a translation matrix as
+defined in linear algebra.
+
+The typical usecase is that where a component has an internal representation
+of the (x,y,z) triplets, such as different registers to read these coordinates,
+and thus implying that the component should be mounted in a certain orientation
+relative to some specific device frame of reference.
+
+For example a device with some kind of screen, where the user is supposed to
+interact with the environment using an accelerometer, gyroscope or magnetometer
+mounted on the same chassis as this screen, will likely take the screen as
+reference to (x,y,z) orientation, with (x,y) corresponding to these axes on the
+screen and (z) being depth, the axis perpendicular to the screen.
+
+For a screen you probably want (x) coordinates to go from negative on the left
+to positive on the right, (y) from negative on the bottom to positive on top
+and (z) depth to be negative under the screen and positive in front of it,
+toward the face of the user.
+
+A sensor can be mounted in any angle along the axes relative to the frame of
+reference. This means that the sensor may be flipped upside-down, left-right,
+or tilted at any angle relative to the frame of reference.
+
+Another frame of reference is how the device with its sensor relates to the
+external world, the environment where the device is deployed. Usually the data
+from the sensor is used to figure out how the device is oriented with respect
+to this world. When using the mounting matrix, the sensor and device orientation
+becomes identical and we can focus on the data as it relates to the surrounding
+world.
+
+Device-to-world examples for some three-dimensional sensor types:
+
+- Accelerometers have their world frame of reference toward the center of
+ gravity, usually to the core of the planet. A reading of the (x,y,z) values
+ from the sensor will give a projection of the gravity vector through the
+ device relative to the center of the planet, i.e. relative to its surface at
+ this point. Up and down in the world relative to the device frame of
+ reference can thus be determined. and users would likely expect a value of
+ 9.81 m/s^2 upwards along the (z) axis, i.e. out of the screen when the device
+ is held with its screen flat on the planets surface and 0 on the other axes,
+ as the gravity vector is projected 1:1 onto the sensors (z)-axis.
+
+ If you tilt the device, the g vector virtually coming out of the display
+ is projected onto the (x,y) plane of the display panel.
+
+ Example:
+
+ ^ z: +g ^ z: > 0
+ ! /!
+ ! x=y=0 / ! x: > 0
+ +--------+ +--------+
+ ! ! ! !
+ +--------+ +--------+
+ ! /
+ ! /
+ v v
+ center of center of
+ gravity gravity
+
+
+ If the device is tilted to the left, you get a positive x value. If you point
+ its top towards surface, you get a negative y axis.
+
+ (---------)
+ ! ! y: -g
+ ! ! ^
+ ! ! !
+ ! !
+ ! ! x: +g <- z: +g -> x: -g
+ ! 1 2 3 !
+ ! 4 5 6 ! !
+ ! 7 8 9 ! v
+ ! * 0 # ! y: +g
+ (---------)
+
+
+- Magnetometers (compasses) have their world frame of reference relative to the
+ geomagnetic field. The system orientation vis-a-vis the world is defined with
+ respect to the local earth geomagnetic reference frame where (y) is in the
+ ground plane and positive towards magnetic North, (x) is in the ground plane,
+ perpendicular to the North axis and positive towards the East and (z) is
+ perpendicular to the ground plane and positive upwards.
+
+
+ ^^^ North: y > 0
+
+ (---------)
+ ! !
+ ! !
+ ! !
+ ! ! >
+ ! ! > North: x > 0
+ ! 1 2 3 ! >
+ ! 4 5 6 !
+ ! 7 8 9 !
+ ! * 0 # !
+ (---------)
+
+ Since the geomagnetic field is not uniform this definition fails if we come
+ closer to the poles.
+
+ Sensors and driver can not and should not take care of this because there
+ are complex calculations and empirical data to be taken care of. We leave
+ this up to user space.
+
+ The definition we take:
+
+ If the device is placed at the equator and the top is pointing north, the
+ display is readable by a person standing upright on the earth surface, this
+ defines a positive y value.
+
+
+- Gyroscopes detects the movement relative the device itself. The angular
+ velocity is defined as orthogonal to the plane of rotation, so if you put the
+ device on a flat surface and spin it around the z axis (such as rotating a
+ device with a screen lying flat on a table), you should get a negative value
+ along the (z) axis if rotated clockwise, and a positive value if rotated
+ counter-clockwise according to the right-hand rule.
+
+
+ (---------) y > 0
+ ! ! v---\
+ ! !
+ ! !
+ ! ! <--\
+ ! ! ! z > 0
+ ! 1 2 3 ! --/
+ ! 4 5 6 !
+ ! 7 8 9 !
+ ! * 0 # !
+ (---------)
+
+
+So unless the sensor is ideally mounted, we need a means to indicate the
+relative orientation of any given sensor of this type with respect to the
+frame of reference.
+
+To achieve this, use the device tree property "mount-matrix" for the sensor.
+
+This supplies a 3x3 rotation matrix in the strict linear algebraic sense,
+to orient the senor axes relative to a desired point of reference. This means
+the resulting values from the sensor, after scaling to proper units, should be
+multiplied by this matrix to give the proper vectors values in three-dimensional
+space, relative to the device or world point of reference.
+
+For more information, consult:
+https://en.wikipedia.org/wiki/Rotation_matrix
+
+The mounting matrix has the layout:
+
+ (mxx, myx, mzx)
+ (mxy, myy, mzy)
+ (mxz, myz, mzz)
+
+Values are intended to be multiplied as:
+
+ x' = mxx * x + myx * y + mzx * z
+ y' = mxy * x + myy * y + mzy * z
+ z' = mxz * x + myz * y + mzz * z
+
+It is represented as an array of strings containing the real values for
+producing the transformation matrix.
+
+Examples:
+
+Identity matrix (nothing happens to the coordinates, which means the device was
+mechanically mounted in an ideal way and we need no transformation):
+
+mount-matrix = "1", "0", "0",
+ "0", "1", "0",
+ "0", "0", "1";
+
+The sensor is mounted 30 degrees (Pi/6 radians) tilted along the X axis, so we
+compensate by performing a -30 degrees rotation around the X axis:
+
+mount-matrix = "1", "0", "0",
+ "0", "0.866", "0.5",
+ "0", "-0.5", "0.866";
+
+The sensor is flipped 180 degrees (Pi radians) around the Z axis, i.e. mounted
+upside-down:
+
+mount-matrix = "0.998", "0.054", "0",
+ "-0.054", "0.998", "0",
+ "0", "0", "1";
+
+???: this does not match "180 degrees" - factors indicate ca. 3 degrees compensation

+ Honeywell pressure sensor of model mprls0025pa.
+
+ This sensor has an I2C and SPI interface. Only the I2C interface is
+ implemented.
+
+ There are many models with different pressure ranges available. The vendor
+ calls them "mpr series". All of them have the identical programming model and
+ differ in the pressure range, unit and transfer function.
+
+ To support different models one need to specify the pressure range as well as
+ the transfer function. Pressure range needs to be converted from its unit to
+ pascal.
+
+ The transfer function defines the ranges of numerical values delivered by the
+ sensor. The minimal range value stands for the minimum pressure and the
+ maximum value also for the maximum pressure with linear relation inside the
+ range.
+
+ Specifications about the devices can be found at:

+
+ There are various applications for the Infra Red contactless temperature
+ sensor and MLX90632 is most suitable for consumer applications where
+ measured object temperature is in range between -20 to 200 degrees
+ Celsius with relative error of measurement below 1 degree Celsius in
+ object temperature range for industrial applications. Since it can
+ operate and measure ambient temperature in range of -20 to 85 degrees
+ Celsius it is suitable also for outdoor use.
+
+ Be aware that electronics surrounding the sensor can increase ambient
+ temperature. MLX90632 can be calibrated to reduce the housing effect via
+ already existing EEPROM parameters.
+
+ Since measured object emissivity effects Infra Red energy emitted,
+ emissivity should be set before requesting the object temperature.

+* Broadcom Keypad Controller device tree bindings
+
+Broadcom Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+This binding is based on the matrix-keymap binding with the following
+changes:
+
+keypad,num-rows and keypad,num-columns are required.
+
+Required SoC Specific Properties:
+- compatible: should be "brcm,bcm-keypad"
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- interrupts: The interrupt number to the cpu.
+
+Board Specific Properties:
+- keypad,num-rows: Number of row lines connected to the keypad
+ controller.
+
+- keypad,num-columns: Number of column lines connected to the
+ keypad controller.
+
+- col-debounce-filter-period: The debounce period for the Column filter.
+
+ KEYPAD_DEBOUNCE_1_ms = 0
+ KEYPAD_DEBOUNCE_2_ms = 1
+ KEYPAD_DEBOUNCE_4_ms = 2

+ KEYPAD_DEBOUNCE_32_ms = 5
+ KEYPAD_DEBOUNCE_64_ms = 6
+ KEYPAD_DEBOUNCE_128_ms = 7
+
+- status-debounce-filter-period: The debounce period for the Status filter.

+ KEYPAD_DEBOUNCE_32_ms = 5
+ KEYPAD_DEBOUNCE_64_ms = 6
+ KEYPAD_DEBOUNCE_128_ms = 7
+
+- row-output-enabled: An optional property indicating whether the row or
+ column is being used as output. If specified the row is being used
+ as the output. Else defaults to column.
+
+- pull-up-enabled: An optional property indicating the Keypad scan mode.
+ If specified implies the keypad scan pull-up has been enabled.
+
+- autorepeat: Boolean, Enable auto repeat feature of Linux input
+ subsystem (optional).
+
+- linux,keymap: The keymap for keys as described in the binding document
+ devicetree/bindings/input/matrix-keymap.txt.
+
+Example:

+* GPIO driven matrix keypad device tree bindings
+
+GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
+The matrix keypad supports multiple row and column lines, a key can be
+placed at each intersection of a unique row and a unique column. The matrix
+keypad can sense a key-press and key-release by means of GPIO lines and
+report the event using GPIO interrupts to the cpu.
+
+Required Properties:
+- compatible: Should be "gpio-matrix-keypad"
+- row-gpios: List of gpios used as row lines. The gpio specifier
+ for this property depends on the gpio controller to
+ which these row lines are connected.
+- col-gpios: List of gpios used as column lines. The gpio specifier
+ for this property depends on the gpio controller to
+ which these column lines are connected.
+- linux,keymap: The definition can be found at
+ bindings/input/matrix-keymap.txt
+
+Optional Properties:
+- linux,no-autorepeat: do no enable autorepeat feature.
+- wakeup-source: use any event on keypad as wakeup event.
+ (Legacy property supported: "linux,wakeup")
+- debounce-delay-ms: debounce interval in milliseconds
+- col-scan-delay-us: delay, measured in microseconds, that is needed
+ before we can scan keypad after activating column gpio
+- drive-inactive-cols: drive inactive columns during scan,
+ default is to turn inactive columns into inputs.
+
+Example:
+ matrix-keypad {
+ compatible = "gpio-matrix-keypad";
+ debounce-delay-ms = <5>;
+ col-scan-delay-us = <2>;
+
+ row-gpios = <&gpio2 25 0

+Input: sysrq reset sequence
+
+A simple binding to represent a set of keys as described in
+include/uapi/linux/input.h. This is to communicate a sequence of keys to the
+sysrq driver. Upon holding the keys for a specified amount of time (if
+specified) the system is sync'ed and reset.
+
+Key sequences are global to the system but all the keys in a set must be coming
+from the same input device.
+
+The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define
+a set of keys.
+
+Required property:
+keyset: array of Linux keycodes, one keycode per cell.
+
+Optional property:
+timeout-ms: duration keys must be pressed together in milliseconds before
+generating a sysrq. If omitted the system is rebooted immediately when a valid
+sequence has been recognized.
+
+Example:
+
+ chosen {
+ linux,sysrq-reset-seq {
+ keyset = <0x03
+ 0x04
+ 0x0a>;
+ timeout-ms = <3000>;
+ };
+ };
+
+Would represent KEY_2, KEY_3 and KEY_9.

+Microchip AT42QT1050 Five-channel Touch Sensor IC
+
+The AT42QT1050 (QT1050) is a QTouchADC sensor device. The device can sense from
+one to five keys, dependent on mode. The QT1050 includes all signal processing
+functions necessary to provide stable sensing under a wide variety of changing
+conditions, and the outputs are fully debounced.
+
+The touchkey device node should be placed inside an I2C bus node.
+
+Required properties:
+- compatible: Must be "microchip,qt1050"
+- reg: The I2C address of the device
+- interrupts: The sink for the touchpad's IRQ output,
+ see ../interrupt-controller/interrupts.txt
+
+Optional properties:
+- wakeup-source: touch keys can be used as a wakeup source
+
+Each button (key) is represented as a sub-node:
+
+Each not specified key or key with linux,code set to KEY_RESERVED gets disabled
+in HW.
+
+Subnode properties:
+- linux,code: Keycode to emit.
+- reg: The key number. Valid values: 0, 1, 2, 3, 4.
+
+Optional subnode-properties:
+
+If a optional property is missing or has a invalid value the default value is
+taken.
+
+- microchip,pre-charge-time-ns:
+ Each touchpad need some time to precharge. The value depends on the mechanical
+ layout.
+ Valid value range: 0 - 637500; values must be a multiple of 2500;
+ default is 0.
+- microchip,average-samples:
+ Number of data samples which are averaged for each read.
+ Valid values: 1, 4, 16, 64, 256, 1024, 4096, 16384; default is 1.
+- microchip,average-scaling:
+ The scaling factor which is used to scale the average-samples.
+ Valid values: 1, 2, 4, 8, 16, 32, 64, 128; default is 1.
+- microchip,threshold:

+* Marvell PXA Keypad controller
+
+Required Properties
+- compatible : should be "marvell,pxa27x-keypad"
+- reg : Address and length of the register set for the device
+- interrupts : The interrupt for the keypad controller
+- marvell,debounce-interval : How long time the key will be
+ recognized when it is pressed. It is a u32 value, and bit[31:16]
+ is debounce interval for direct key and bit[15:0] is debounce
+ interval for matrix key. The value is in binary number of 2ms
+
+Optional Properties For Matrix Keyes
+Please refer to matrix-keymap.txt
+
+Optional Properties for Direct Keyes
+- marvell,direct-key-count : How many direct keyes are used.
+- marvell,direct-key-mask : The mask indicates which keyes
+ are used. If bit[X] of the mask is set, the direct key X
+ is used.
+- marvell,direct-key-low-active : Direct key status register
+ tells the level of pins that connects to the direct keyes.
+ When this property is set, it means that when the pin level
+ is low, the key is pressed(active).
+- marvell,direct-key-map : It is a u16 array. Each item indicates
+ the linux key-code for the direct key.
+
+Optional Properties For Rotary
+- marvell,rotary0 : It is a u32 value. Bit[31:16] is the
+ linux key-code for rotary up. Bit[15:0] is the linux key-code
+ for rotary down. It is for rotary 0.
+- marvell,rotary1 : Same as marvell,rotary0. It is for rotary 1.
+- marvell,rotary-rel-key : When rotary is used for relative axes
+ in the device, the value indicates the key-code for relative
+ axes measurement in the device. It is a u32 value. Bit[31:16]
+ is for rotary 1, and Bit[15:0] is for rotary 0.

+Rotary encoder DT bindings
+
+Required properties:
+- gpios: a spec for at least two GPIOs to be used, most significant first
+
+Optional properties:
+- linux,axis: the input subsystem axis to map to this rotary encoder.
+ Defaults to 0 (ABS_X / REL_X)
+- rotary-encoder,steps: Number of steps in a full turnaround of the
+ encoder. Only relevant for absolute axis. Defaults to 24 which is a
+ typical value for such devices.
+- rotary-encoder,relative-axis: register a relative axis rather than an
+ absolute one. Relative axis will only generate +1/-1 events on the input
+ device, hence no steps need to be passed.
+- rotary-encoder,rollover: Automatic rollover when the rotary value becomes
+ greater than the specified steps or smaller than 0. For absolute axis only.
+- rotary-encoder,steps-per-period: Number of steps (stable states) per period.
+ The values have the following meaning:
+ 1: Full-period mode (default)
+ 2: Half-period mode
+ 4: Quarter-period mode
+- wakeup-source: Boolean, rotary encoder can wake up the system.
+- rotary-encoder,encoding: String, the method used to encode steps.
+ Supported are "gray" (the default and more common) and "binary".
+
+Deprecated properties:
+- rotary-encoder,half-period: Makes the driver work on half-period mode.
+ This property is deprecated. Instead, a 'steps-per-period ' value should
+ be used, such as "rotary-encoder,steps-per-period = <2>".
+
+See Documentation/input/devices/rotary-encoder.rst for more information.

+Example:
+
+ rotary@0 {

+* Samsung's Keypad Controller device tree bindings
+
+Samsung's Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+Required SoC Specific Properties:
+- compatible: should be one of the following
+ - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad
+ controller.
+ - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad
+ controller.
+

+Required Board Specific Properties:
+- samsung,keypad-num-rows: Number of row lines connected to the keypad
+ controller.
+
+- samsung,keypad-num-columns: Number of column lines connected to the
+ keypad controller.
+
+- Keys represented as child nodes: Each key connected to the keypad
+ controller is represented as a child node to the keypad controller
+ device node and should include the following properties.
+ - keypad,row: the row number to which the key is connected.
+ - keypad,column: the column number to which the key is connected.
+ - linux,code: the key-code to be reported when the key is pressed
+ and released.
+
+- pinctrl-0: Should specify pin control groups used for this controller.
+- pinctrl-names: Should contain only one value - "default".
+
+Optional Properties:
+- wakeup-source: use any event on keypad as wakeup event.
+ (Legacy property supported: "linux,input-wakeup")

+Optional Properties:
+
+- ti,palmas-long-press-seconds: Duration in seconds which the power
+ button should be kept pressed for Palmas to power off automatically.
+ NOTE: This depends on OTP support and POWERHOLD signal configuration
+ on platform. Valid values are 6, 8, 10 and 12.
+- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds
+ which the power button should be kept pressed for Palmas to register
+ a press for debouncing purposes. NOTE: This depends on specific
+ Palmas variation capability. Valid values are 15, 100, 500 and 1000.

+Freescale mx25 TS conversion queue module
+
+mx25 touchscreen conversion queue module which controls the ADC unit of the
+mx25 for attached touchscreens.
+
+Required properties:
+ - compatible: Should be "fsl,imx25-tcq".
+ - reg: Memory range of the device.
+ - interrupts: Should be the interrupt number associated with this module within
+ the tscadc unit (<0>).
+ - fsl,wires: Should be '<4>' or '<5>'
+
+Optional properties:
+ - fsl,pen-debounce-ns: Pen debounce time in nanoseconds.
+ - fsl,pen-threshold: Pen-down threshold for the touchscreen. This is a value
+ between 1 and 4096. It is the ratio between the internal reference voltage
+ and the measured voltage after the plate was precharged. Resistance between
+ plates and therefore the voltage decreases with pressure so that a smaller
+ value is equivalent to a higher pressure.
+ - fsl,settling-time-ns: Settling time in nanoseconds. The settling time is before
+ the actual touch detection to wait for an even charge distribution in the
+ plate.
+
+This device includes two conversion queues which can be added as subnodes.
+The first queue is for the touchscreen, the second for general purpose ADC.
+
+Example:
+ tsc: tcq@50030400 {
+ compatible = "fsl,imx25-tcq";
+ reg = <0x50030400 0x60>;

+Interconnect Provider Device Tree Bindings
+=========================================
+
+The purpose of this document is to define a common set of generic interconnect
+providers/consumers properties.
+
+
+= interconnect providers =
+
+The interconnect provider binding is intended to represent the interconnect
+controllers in the system. Each provider registers a set of interconnect
+nodes, which expose the interconnect related capabilities of the interconnect
+to consumer drivers. These capabilities can be throughput, latency, priority
+etc. The consumer drivers set constraints on interconnect path (or endpoints)
+depending on the use case. Interconnect providers can also be interconnect
+consumers, such as in the case where two network-on-chip fabrics interface
+directly.
+
+Required properties:
+- compatible : contains the interconnect provider compatible string
+- #interconnect-cells : number of cells in a interconnect specifier needed to
+ encode the interconnect node id and optionally add a
+ path tag
+
+Example:
+
+ snoc: interconnect@580000 {
+ compatible = "qcom,msm8916-snoc";
+ #interconnect-cells = <1>;
+ reg = <0x580000 0x14000>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
+ <&rpmcc RPM_SMD_SNOC_A_CLK>;
+ };
+
+
+= interconnect consumers =
+
+The interconnect consumers are device nodes which dynamically express their
+bandwidth requirements along interconnect paths they are connected to. There
+can be multiple interconnect providers on a SoC and the consumer may consume
+multiple paths from different providers depending on use case and the
+components it has to interact with.
+
+Required properties:
+interconnects : Pairs of phandles and interconnect provider specifier to denote
+ the edge source and destination ports of the interconnect path.
+ An optional path tag value could specified as additional argument
+ to both endpoints and in such cases, this information will be passed
+ to the interconnect framework to do aggregation based on the attached
+ tag.
+
+Optional properties:
+interconnect-names : List of interconnect path name strings sorted in the same
+ order as the interconnects property. Consumers drivers will use
+ interconnect-names to match interconnect paths with interconnect
+ specifier pairs.
+
+ Reserved interconnect names:
+ * dma-mem: Path from the device to the main memory of
+ the system
+
+Example:
+
+ sdhci@7864000 {
+ ...
+ interconnects = <&pnoc MASTER_SDCC_1 &bimc SLAVE_EBI_CH0>;
+ interconnect-names = "sdhc-mem";
+ };
+
+Example with path tags:
+
+ gnoc: interconnect@17900000 {
+ ...
+ interconnect-cells = <2>;
+ };
+
+ mnoc: interconnect@1380000 {
+ ...
+ interconnect-cells = <2>;
+ };
+
+ cpu@0 {
+ ...
+ interconnects = <&gnoc MASTER_APPSS_PROC 3 &mnoc SLAVE_EBI1 3>;
+ }

+
+description: |
+ The Samsung Exynos SoC has many buses for data transfer between DRAM and
+ sub-blocks in SoC. Most Exynos SoCs share the common architecture for buses.
+ Generally, each bus of Exynos SoC includes a source clock and a power line,
+ which are able to change the clock frequency of the bus in runtime. To
+ monitor the usage of each bus in runtime, the driver uses the PPMU (Platform
+ Performance Monitoring Unit), which is able to measure the current load of
+ sub-blocks.
+
+ The Exynos SoC includes the various sub-blocks which have the each AXI bus.
+ The each AXI bus has the owned source clock but, has not the only owned power
+ line. The power line might be shared among one more sub-blocks. So, we can
+ divide into two type of device as the role of each sub-block. There are two
+ type of bus devices as following::
+ - parent bus device
+ - passive bus device
+
+ Basically, parent and passive bus device share the same power line. The
+ parent bus device can only change the voltage of shared power line and the
+ rest bus devices (passive bus device) depend on the decision of the parent
+ bus device. If there are three blocks which share the VDD_xxx power line,
+ Only one block should be parent device and then the rest blocks should depend
+ on the parent device as passive device.
+
+ VDD_xxx |--- A block (parent)
+ |--- B block (passive)
+ |--- C block (passive)
+
+ There are a little different composition among Exynos SoC because each Exynos
+ SoC has different sub-blocks. Therefore, such difference should be specified
+ in devicetree file instead of each device driver. In result, this driver is
+ able to support the bus frequency for all Exynos SoCs.
+
+ Detailed correlation between sub-blocks and power line according
+ to Exynos SoC::
+ - In case of Exynos3250, there are two power line as following::
+ VDD_MIF |--- DMC (Dynamic Memory Controller)
+

+TB10x Top Level Interrupt Controller
+====================================
+
+The Abilis TB10x SOC contains a custom interrupt controller. It performs
+one-to-one mapping of external interrupt sources to CPU interrupts and
+provides support for reconfigurable trigger modes.
+
+Required properties
+-------------------
+
+- compatible: Should be "abilis,tb10x-ictl"
+- reg: specifies physical base address and size of register range.
+- interrupt-congroller: Identifies the node as an interrupt controller.
+- #interrupt cells: Specifies the number of cells used to encode an interrupt
+ source connected to this controller. The value shall be 2.

+ The Apple Interrupt Controller is a simple interrupt controller present on

+ "Apple Silicon" Macs.
+
+ It provides the following features:
+
+ - Level-triggered hardware IRQs wired to SoC blocks
+ - Single mask bit per IRQ
+ - Per-IRQ affinity setting
+ - Automatic masking on event delivery (auto-ack)
+ - Software triggering (ORed with hw line)
+ - 2 per-CPU IPIs (meant as "self" and "other", but they are interchangeable
+ if not symmetric)
+ - Automatic prioritization (single event/ack register per CPU, lower IRQs =
+ higher priority)
+ - Automatic masking on ack
+ - Default "this CPU" register view and explicit per-CPU views
+
+ This device also represents the FIQ interrupt sources on platforms using AIC,

+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ The 1st cell contains the interrupt number for the interrupt type.
+
+ The 2nd cell is the priority of the interrupt.
+
+- reg : Specifies base physical address(s) and size of the NVIC registers.
+ This is at a fixed address (0xe000e100) and size (0xc00).
+
+- arm,num-irq-priority-bits: The number of priority bits implemented by the
+ given SoC
+
+Example:

+* ARM Versatile FPGA interrupt controller
+
+One or more FPGA IRQ controllers can be synthesized in an ARM reference board
+such as the Integrator or Versatile family. The output of these different

+- compatible: "arm,versatile-fpga-irq"
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells: The number of cells to define the interrupts. Must be 1

+- reg: The register bank for the FPGA interrupt controller.
+- clear-mask: a u32 number representing the mask written to clear all IRQs
+ on the controller at boot for example.
+- valid-mask: a u32 number representing a bit mask determining which of
+ the interrupts are valid. Unconnected/unused lines are set to 0, and
+ the system till not make it possible for devices to request these
+ interrupts.
+
+The "oxsemi,ox810se-rps-irq" compatible is deprecated.

+
+Optional properties:
+- interrupts: if the FPGA IRQ controller is cascaded, i.e. if its IRQ
+ output is simply connected to the input of another IRQ controller,
+ then the parent IRQ shall be specified in this property.

+Broadcom BCM6345-style Level 1 interrupt controller
+
+This block is a first level interrupt controller that is typically connected
+directly to one of the HW INT lines on each CPU.
+
+Key elements of the hardware design include:
+
+- 32, 64 or 128 incoming level IRQ lines
+
+- Most onchip peripherals are wired directly to an L1 input
+
+- A separate instance of the register set for each CPU, allowing individual
+ peripheral IRQs to be routed to any CPU
+
+- Contains one or more enable/status word pairs per CPU
+
+- No atomic set/clear operations
+
+- No polarity/level/edge settings
+
+- No FIFO or priority encoder logic; software is expected to read all
+ 2-4 status words to determine which IRQs are pending
+
+Required properties:
+
+- compatible: should be "brcm,bcm<soc>-l1-intc", "brcm,bcm6345-l1-intc"
+- reg: specifies the base physical address and size of the registers;
+ the number of supported IRQs is inferred from the size argument
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+ source, should be 1.
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node; valid values depend on the type of parent interrupt controller
+
+If multiple reg ranges and interrupt-parent entries are present on an SMP
+system, the driver will allow IRQ SMP affinity to be set up through the
+/proc/irq/ interface. In the simplest possible configuration, only one
+reg range and one interrupt-parent is needed.
+
+The driver operates in native CPU endian by default, there is no support for
+specifying an alternative endianness.
+
+Example:
+
+periph_intc: interrupt-controller@10000000 {

+ This interrupt controller hardware is a second level interrupt controller that
+ is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based
+ platforms. It can be found on BCM7xxx products starting with BCM7120.
+
+ Such an interrupt controller has the following hardware design:
+
+ - outputs multiple interrupts signals towards its interrupt controller parent
+
+ - controls how some of the interrupts will be flowing, whether they will
+ directly output an interrupt signal towards the interrupt controller parent,
+ or if they will output an interrupt signal at this 2nd level interrupt
+ controller, in particular for UARTs
+
+ - has one 32-bit enable word and one 32-bit status word
+
+ - no atomic set/clear operations
+
+ - not all bits within the interrupt controller actually map to an interrupt
+
+ The typical hardware layout for this controller is represented below:
+
+ 2nd level interrupt line Outputs for the parent controller (e.g: ARM GIC)
+
+ 0 -----[ MUX ] ------------|==========> GIC interrupt 75
+ \-----------\

+
+ The BCM3380 Level 1 / Level 2 interrupt controller shows up in various forms

+===========================================
+C-SKY Multi-processors Interrupt Controller
+===========================================
+
+C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
+SMP soc, and it also could be used in non-SMP system.
+
+Interrupt number definition:
+ 0-15 : software irq, and we use 15 as our IPI_IRQ.
+ 16-31 : private irq, and we use 16 as the co-processor timer.
+ 31-1024: common irq for soc ip.
+
+Interrupt trigger mode: (Defined in dt-bindings/interrupt-controller/irq.h)
+ IRQ_TYPE_LEVEL_HIGH (default)
+ IRQ_TYPE_LEVEL_LOW
+ IRQ_TYPE_EDGE_RISING
+ IRQ_TYPE_EDGE_FALLING

+description: |
+ The Messaging Unit module enables two processors within the SoC to
+ communicate and coordinate by passing messages (e.g. data, status
+ and control) through the MU interface. The MU also provides the ability
+ for one processor (A side) to signal the other processor (B side) using
+ interrupts.
+
+ Because the MU manages the messaging between processors, the MU uses
+ different clocks (from each side of the different peripheral buses).
+ Therefore, the MU must synchronize the accesses from one side to the
+ other. The MU accomplishes synchronization using two sets of matching
+ registers (Processor A-side, Processor B-side).

+Hisilicon mbigen device tree bindings.
+=======================================
+
+Mbigen means: message based interrupt generator.
+
+MBI is kind of msi interrupt only used on Non-PCI devices.
+
+To reduce the wired interrupt number connected to GIC,
+Hisilicon designed mbigen to collect and generate interrupt.
+
+
+Non-pci devices can connect to mbigen and generate the
+interrupt by writing ITS register.
+
+The mbigen chip and devices connect to mbigen have the following properties:
+
+Mbigen main node required properties:
+-------------------------------------------
+- compatible: Should be "hisilicon,mbigen-v2"
+
+- reg: Specifies the base physical address and size of the Mbigen
+ registers.
+
+Mbigen sub node required properties:
+------------------------------------------
+- interrupt controller: Identifies the node as an interrupt controller
+
+- msi-parent: Specifies the MSI controller this mbigen use.
+ For more detail information,please refer to the generic msi-parent binding in
+ Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+- num-pins: the total number of pins implemented in this Mbigen
+ instance.
+
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value must be 2.
+
+ The 1st cell is hardware pin number of the interrupt.This number is local to
+ each mbigen chip and in the range from 0 to the maximum interrupts number
+ of the mbigen.
+
+ The 2nd cell is the interrupt trigger type.
+ The value of this cell should be:
+ 1: rising edge triggered
+ or
+ 4: high level triggered
+
+Examples:
+
+ mbigen_chip_dsa {
+ compatible = "hisilicon,mbigen-v2";
+ reg = <0x0 0xc0080000 0x0 0x10000>;
+
+ mbigen_gmac:intc_gmac {
+ interrupt-controller;
+ msi-parent = <&its_dsa 0x40b1c>;
+ num-pins = <9>;
+ #interrupt-cells = <2>;
+ };
+
+ mbigen_i2c:intc_i2c {
+ interrupt-controller;
+ msi-parent = <&its_dsa 0x40b0e>;
+ num-pins = <2>;
+ #interrupt-cells = <2>;
+ };
+ };
+
+Devices connect to mbigen required properties:
+----------------------------------------------------
+-interrupts:Specifies the interrupt source.
+ For the specific information of each cell in this property,please refer to
+ the "interrupt-cells" description mentioned above.
+
+Examples:
+ gmac0: ethernet@c2080000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0 0xc2080000 0 0x20000>,
+ <0 0xc0000000 0 0x1000>;
+ interrupt-parent = <&mbigen_device_gmac>;
+ interrupts = <656 1>,
+ <657 1>;

+* ImgTec Powerdown Controller (PDC) Interrupt Controller Binding
+
+This binding specifies what properties must be available in the device tree
+representation of a PDC IRQ controller. This has a number of input interrupt
+lines which can wake the system, and are passed on through output interrupt
+lines.
+
+Required properties:
+
+ - compatible: Specifies the compatibility list for the interrupt controller.
+ The type shall be <string> and the value shall include "img,pdc-intc".
+
+ - reg: Specifies the base PDC physical address(s) and size(s) of the
+ addressable register space. The type shall be <prop-encoded-array>.
+
+ - interrupt-controller: The presence of this property identifies the node
+ as an interrupt controller. No property value shall be defined.
+
+ - #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ - num-perips: Number of waking peripherals.
+
+ - num-syswakes: Number of SysWake inputs.
+
+ - interrupts: List of interrupt specifiers. The first specifier shall be the
+ shared SysWake interrupt, and remaining specifies shall be PDC peripheral
+ interrupts in order.
+
+* Interrupt Specifier Definition
+
+ Interrupt specifiers consists of 2 cells encoded as follows:
+
+ - <1st-cell>: The interrupt-number that identifies the interrupt source.
+ 0-7: Peripheral interrupts
+ 8-15: SysWake interrupts
+
+ - <2nd-cell>: The level-sense information, encoded using the Linux interrupt
+ flags as follows (only 4 valid for peripheral interrupts):
+ 0 = none (decided by software)
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 3 = both edge triggered
+ 4 = active-high level-sensitive (required for perip irqs)
+ 8 = active-low level-sensitive
+
+* Examples
+
+Example 1:
+
+ /*
+ * TZ1090 PDC block
+ */
+ pdc: pdc@02006000 {
+ // This is an interrupt controller node.
+ interrupt-controller;
+
+ // Three cells to encode interrupt sources.
+ #interrupt-cells = <2>;
+
+ // Offset address of 0x02006000 and size of 0x1000.
+ reg = <0x02006000 0x1000>;
+
+ // Compatible with Meta hardware trigger block.
+ compatible = "img,pdc-intc";
+
+ // Three peripherals are connected.
+ num-perips = <3>;
+
+ // Four SysWakes are connected.
+ num-syswakes = <4>;
+
+ interrupts = <18 4 /* level */>, /* Syswakes */
+ <30 4 /* level */>, /* Peripheral 0 (RTC) */
+ <29 4 /* level */>, /* Peripheral 1 (IR) */
+ <31 4 /* level */>; /* Peripheral 2 (WDT) */
+ };
+
+Example 2:
+
+ /*
+ * An SoC peripheral that is wired through the PDC.
+ */
+ rtc0 {
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&pdc>;
+
+ // Interrupt source Peripheral 0
+ interrupts = <0 /* Peripheral 0 (RTC) */
+ 4> /* IRQ_TYPE_LEVEL_HIGH */
+ };
+
+Example 3:
+
+ /*
+ * An interrupt generating device that is wired to a SysWake pin.
+ */
+ touchscreen0 {
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&pdc>;
+
+ // Interrupt source SysWake 0 that is active-low level-sensitive
+ interrupts = <8 /* SysWake0 */
+ 8 /* IRQ_TYPE_LEVEL_LOW */>;
+ };

+Specifying interrupt information for devices
+============================================
+
+1) Interrupt client nodes
+-------------------------
+
+Nodes that describe devices which generate interrupts must contain an
+"interrupts" property, an "interrupts-extended" property, or both. If both are
+present, the latter should take precedence; the former may be provided simply
+for compatibility with software that does not recognize the latter. These
+properties contain a list of interrupt specifiers, one per output interrupt. The
+format of the interrupt specifier is determined by the interrupt controller to
+which the interrupts are routed; see section 2 below for details.
+
+ Example:
+ interrupt-parent = <&intc1>;
+ interrupts = <5 0>, <6 0>;
+
+The "interrupt-parent" property is used to specify the controller to which
+interrupts are routed and contains a single phandle referring to the interrupt
+controller node. This property is inherited, so it may be specified in an
+interrupt client node or in any of its parent nodes. Interrupts listed in the
+"interrupts" property are always in reference to the node's interrupt parent.
+
+The "interrupts-extended" property is a special form; useful when a node needs
+to reference multiple interrupt parents or a different interrupt parent than
+the inherited one. Each entry in this property contains both the parent phandle
+and the interrupt specifier.
+
+ Example:
+ interrupts-extended = <&intc1 5 1>, <&intc2 1 0>;
+
+2) Interrupt controller nodes
+-----------------------------
+
+A device is marked as an interrupt controller with the "interrupt-controller"
+property. This is a empty, boolean property. An additional "#interrupt-cells"
+property defines the number of cells needed to specify a single interrupt.
+
+It is the responsibility of the interrupt controller's binding to define the
+length and format of the interrupt specifier. The following two variants are
+commonly used:
+
+ a) one cell
+ -----------
+ The #interrupt-cells property is set to 1 and the single cell defines the
+ index of the interrupt within the controller.
+
+ Example:
+
+ vic: intc@10140000 {
+ compatible = "arm,versatile-vic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x10140000 0x1000>;
+ };
+
+ sic: intc@10003000 {
+ compatible = "arm,versatile-sic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x10003000 0x1000>;
+ interrupt-parent = <&vic>;
+ interrupts = <31>; /* Cascaded to vic */
+ };
+
+ b) two cells
+ ------------
+ The #interrupt-cells property is set to 2 and the first cell defines the
+ index of the interrupt within the controller, while the second cell is used
+ to specify any of the following flags:
+ - bits[3:0] trigger type and level flags
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+
+ Example:
+
+ i2c@7000c000 {
+ gpioext: gpio-adnp@41 {
+ compatible = "ad,gpio-adnp";
+ reg = <0x41>;
+
+ interrupt-parent = <&gpio>;
+ interrupts = <160 1>;
+
+ gpio-controller;
+ #gpio-cells = <1>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+
+ nr-gpios = <64>;
+ };
+
+ sx8634@2b {
+ compatible = "smtc,sx8634";
+ reg = <0x2b>;
+
+ interrupt-parent = <&gpioext>;
+ interrupts = <3 0x8>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ threshold = <0x40>;
+ sensitivity = <7>;
+ };
+ };
+
+3) Interrupt wakeup parent
+--------------------------
+
+Some interrupt controllers in a SoC, are always powered on and have a select
+interrupts routed to them, so that they can wakeup the SoC from suspend. These
+interrupt controllers do not fall into the category of a parent interrupt
+controller and can be specified by the "wakeup-parent" property and contain a
+single phandle referring to the wakeup capable interrupt controller.
+
+ Example:
+ wakeup-parent = <&pdc_intc>;

+The Marvell ICU (Interrupt Consolidation Unit) controller is

+requests on input wires to MSG memory mapped transactions to the GIC.

+
+Required properties:
+
+- compatible: Should be "marvell,cp110-icu"
+
+- reg: Should contain ICU registers location and length.
+
+Subnodes: Each group of interrupt is declared as a subnode of the ICU,

+Marvell SEI (System Error Interrupt) Controller
+-----------------------------------------------
+
+Marvell SEI (System Error Interrupt) controller is an interrupt
+aggregator. It receives interrupts from several sources and aggregates
+them to a single interrupt line (an SPI) on the parent interrupt
+controller.
+
+This interrupt controller can handle up to 64 SEIs, a set comes from the
+AP and is wired while a second set comes from the CPs by the mean of
+MSIs.
+
+Required properties:
+
+- compatible: should be one of:
+ * "marvell,ap806-sei"
+- reg: SEI registers location and length.
+- interrupts: identifies the parent IRQ that will be triggered.
+- #interrupt-cells: number of cells to define an SEI wired interrupt
+ coming from the AP, should be 1. The cell is the IRQ
+ number.
+- interrupt-controller: identifies the node as an interrupt controller
+ for AP interrupts.
+- msi-controller: identifies the node as an MSI controller for the CPs
+ interrupts.
+
+Example:
+
+ sei: interrupt-controller@3f0200 {
+ compatible = "marvell,ap806-sei";
+ reg = <0x3f0200 0x40>;
+ interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
+ #interrupt-cells = <1>;

+ interrupts and generate a pulse signal to parent interrupt controller when
+ flush command is executed. With CIRQ, MCUSYS can be completely turned off

+Microchip PIC32 Interrupt Controller
+====================================
+
+The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
+It handles all internal and external interrupts. This controller exists outside
+of the CPU and is the arbitrator of all interrupts (including interrupts from
+the CPU itself) before they are presented to the CPU.
+
+External interrupts have a software configurable edge polarity. Non external
+interrupts have a type and polarity that is determined by the source of the
+interrupt.
+
+Required properties
+-------------------
+
+- compatible: Should be "microchip,pic32mzda-evic"
+- reg: Specifies physical base address and size of register range.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt cells: Specifies the number of cells used to encode an interrupt
+ source connected to this controller. The value shall be 2 and interrupt
+ descriptor shall have the following format:
+
+ <hw_irq irq_type>
+
+ hw_irq - represents the hardware interrupt number as in the data sheet.
+ irq_type - is used to describe the type and polarity of an interrupt. For
+ internal interrupts use IRQ_TYPE_EDGE_RISING for non persistent interrupts and
+ IRQ_TYPE_LEVEL_HIGH for persistent interrupts. For external interrupts use
+ IRQ_TYPE_EDGE_RISING or IRQ_TYPE_EDGE_FALLING to select the desired polarity.
+
+Optional properties
+-------------------
+- microchip,external-irqs: u32 array of external interrupts with software
+ polarity configuration. This array corresponds to the bits in the INTCON
+ SFR.
+
+Example
+-------
+
+evic: interrupt-controller@1f810000 {
+ compatible = "microchip,pic32mzda-evic";
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ reg = <0x1f810000 0x1000>;
+ microchip,external-irqs = <3 8 13 18 23>;
+};
+
+Each device/peripheral must request its interrupt line with the associated type
+and polarity.
+
+Internal interrupt DTS snippet
+------------------------------
+
+device@1f800000 {
+ ...
+ interrupts = <113 IRQ_TYPE_LEVEL_HIGH>;
+ ...
+};
+
+External interrupt DTS snippet
+------------------------------
+

+This document describes the generic device tree binding for MSI controllers and
+their master(s).
+
+Message Signaled Interrupts (MSIs) are a class of interrupts generated by a
+write to an MMIO address.
+
+MSIs were originally specified by PCI (and are used with PCIe), but may also be
+used with other busses, and hence a mechanism is required to relate devices on
+those busses to the MSI controllers which they are capable of using,
+potentially including additional information.
+
+MSIs are distinguished by some combination of:
+
+- The doorbell (the MMIO address written to).
+
+ Devices may be configured by software to write to arbitrary doorbells which
+ they can address. An MSI controller may feature a number of doorbells.
+
+- The payload (the value written to the doorbell).
+
+ Devices may be configured to write an arbitrary payload chosen by software.
+ MSI controllers may have restrictions on permitted payloads.
+
+- Sideband information accompanying the write.
+
+ Typically this is neither configurable nor probeable, and depends on the path
+ taken through the memory system (i.e. it is a property of the combination of
+ MSI controller and device rather than a property of either in isolation).
+
+
+MSI controllers:
+================
+
+An MSI controller signals interrupts to a CPU when a write is made to an MMIO
+address by some master. An MSI controller may feature a number of doorbells.
+
+Required properties:
+--------------------
+
+- msi-controller: Identifies the node as an MSI controller.
+
+Optional properties:
+--------------------
+
+- #msi-cells: The number of cells in an msi-specifier, required if not zero.
+
+ Typically this will encode information related to sideband data, and will
+ not encode doorbells or payloads as these can be configured dynamically.
+
+ The meaning of the msi-specifier is defined by the device tree binding of
+ the specific MSI controller.
+
+
+MSI clients
+===========
+
+MSI clients are devices which generate MSIs. For each MSI they wish to
+generate, the doorbell and payload may be configured, though sideband
+information may not be configurable.
+
+Required properties:
+--------------------
+
+- msi-parent: A list of phandle + msi-specifier pairs, one for each MSI
+ controller which the device is capable of using.
+
+ This property is unordered, and MSIs may be allocated from any combination of
+ MSI controllers listed in the msi-parent property.
+
+ If a device has restrictions on the allocation of MSIs, these restrictions
+ must be described with additional properties.

+NVIDIA Legacy Interrupt Controller
+
+All Tegra SoCs contain a legacy interrupt controller that routes
+interrupts to the GIC, and also serves as a wakeup source. It is also
+referred to as "ictlr", hence the name of the binding.
+
+The HW block exposes a number of interrupt controllers, each
+implementing a set of 32 interrupts.
+
+Required properties:
+
+- compatible : should be: "nvidia,tegra<chip>-ictlr". The LIC on
+ subsequent SoCs remained backwards-compatible with Tegra30, so on
+ Tegra generations later than Tegra30 the compatible value should
+ include "nvidia,tegra30-ictlr".
+- reg : Specifies base physical address and size of the registers.
+ Each controller must be described separately (Tegra20 has 4 of them,
+ whereas Tegra30 and later have 5).
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value must be 3.
+
+Notes:
+
+- Because this HW ultimately routes interrupts to the GIC, the
+ interrupt specifier must be that of the GIC.
+- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
+ are explicitly forbidden.
+
+Example:
+
+ ictlr: interrupt-controller@60004000 {
+ compatible = "nvidia,tegra20-ictlr", "nvidia,tegra-ictlr";
+ reg = <0x60004000 64>,

+* Open PIC Binding
+
+This binding specifies what properties must be available in the device tree
+representation of an Open PIC compliant interrupt controller. This binding is
+based on the binding defined for Open PIC in [1] and is a superset of that
+binding.
+
+Required properties:
+
+ NOTE: Many of these descriptions were paraphrased here from [1] to aid
+ readability.
+
+ - compatible: Specifies the compatibility list for the PIC. The type
+ shall be <string> and the value shall include "open-pic".
+
+ - reg: Specifies the base physical address(s) and size(s) of this
+ PIC's addressable register space. The type shall be <prop-encoded-array>.
+
+ - interrupt-controller: The presence of this property identifies the node
+ as an Open PIC. No property value shall be defined.
+
+ - #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ - #address-cells: Specifies the number of cells needed to encode an
+ address. The type shall be <u32> and the value shall be 0. As such,
+ 'interrupt-map' nodes do not have to specify a parent unit address.
+
+Optional properties:
+
+ - pic-no-reset: The presence of this property indicates that the PIC
+ shall not be reset during runtime initialization. No property value shall
+ be defined. The presence of this property also mandates that any
+ initialization related to interrupt sources shall be limited to sources
+ explicitly referenced in the device tree.
+
+* Interrupt Specifier Definition
+
+ Interrupt specifiers consists of 2 cells encoded as
+ follows:
+
+ - <1st-cell>: The interrupt-number that identifies the interrupt source.
+
+ - <2nd-cell>: The level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+* Examples
+
+Example 1:
+
+ /*
+ * An Open PIC interrupt controller
+ */
+ mpic: pic@40000 {
+ // This is an interrupt controller node.
+ interrupt-controller;
+
+ // No address cells so that 'interrupt-map' nodes which reference
+ // this Open PIC node do not need a parent address specifier.
+ #address-cells = <0>;
+
+ // Two cells to encode interrupt sources.
+ #interrupt-cells = <2>;
+
+ // Offset address of 0x40000 and size of 0x40000.
+ reg = <0x40000 0x40000>;
+
+ // Compatible with Open PIC.
+ compatible = "open-pic";
+
+ // The PIC shall not be reset.
+ pic-no-reset;
+ };
+
+Example 2:
+
+ /*
+ * An interrupt generating device that is wired to an Open PIC.
+ */
+ serial0: serial@4500 {
+ // Interrupt source '42' that is active high level-sensitive.
+ // Note that there are only two cells as specified in the interrupt
+ // parent's '#interrupt-cells' property.
+ interrupts = <42 2>;
+
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&mpic>;

+description: |
+ Qualcomm Technologies Inc. SoCs based on the RPM Hardened architecture have a
+ Power Domain Controller (PDC) that is on always-on domain. In addition to
+ providing power control for the power domains, the hardware also has an
+ interrupt controller that can be used to help detect edge low interrupts as
+ well detect interrupts when the GIC is non-operational.
+
+ GIC is parent interrupt controller at the highest level. Platform interrupt
+ controller PDC is next in hierarchy, followed by others. Drivers requiring
+ wakeup capabilities of their device interrupts routed through the PDC, must
+ specify PDC as their interrupt controller and request the PDC port associated
+ with the GIC interrupt. See example below.

+RISC-V Hart-Level Interrupt Controller (HLIC)
+---------------------------------------------
+
+RISC-V cores include Control Status Registers (CSRs) which are local to each
+CPU core (HART in RISC-V terminology) and can be read or written by software.
+Some of these CSRs are used to control local interrupts connected to the core.
+Every interrupt is ultimately routed through a hart's HLIC before it
+interrupts that hart.
+
+The RISC-V supervisor ISA manual specifies three interrupt sources that are
+attached to every HLIC: software interrupts, the timer interrupt, and external
+interrupts. Software interrupts are used to send IPIs between cores. The
+timer interrupt comes from an architecturally mandated real-time timer that is
+controlled via Supervisor Binary Interface (SBI) calls and CSR reads. External
+interrupts connect all other device interrupts to the HLIC, which are routed
+via the platform-level interrupt controller (PLIC).
+
+All RISC-V systems that conform to the supervisor ISA specification are
+required to have a HLIC with these three interrupt sources present. Since the
+interrupt map is defined by the ISA it's not listed in the HLIC's device tree
+entry, though external interrupt controllers (like the PLIC, for example) will
+need to define how their interrupts map to the relevant HLICs. This means
+a PLIC interrupt property will typically list the HLICs for all present HARTs
+in the system.
+
+Required properties:
+- compatible : "riscv,cpu-intc"
+- #interrupt-cells : should be <1>. The interrupt sources are defined by the
+ RISC-V supervisor ISA manual, with only the following three interrupts being
+ defined for supervisor mode:
+ - Source 1 is the supervisor software interrupt, which can be sent by an SBI
+ call and is reserved for use by software.
+ - Source 5 is the supervisor timer interrupt, which can be configured by
+ SBI calls and implements a one-shot timer.
+ - Source 9 is the supervisor external interrupt, which chains to all other
+ device interrupts.
+- interrupt-controller : Identifies the node as an interrupt controller
+
+Furthermore, this interrupt-controller MUST be embedded inside the cpu
+definition of the hart whose CSRs control these local interrupts.
+
+An example device tree entry for a HLIC is show below.
+
+ cpu1: cpu@1 {
+ compatible = "riscv";
+ ...
+ cpu1-intc: interrupt-controller {
+ #interrupt-cells = <1>;
+ compatible = "sifive,fu540-c000-cpu-intc", "riscv,cpu-intc";
+ interrupt-controller;

+description: |
+ Samsung's Exynos4 architecture includes a interrupt combiner controller which
+ can combine interrupt sources as a group and provide a single interrupt
+ request for the group. The interrupt request from each group are connected to
+ a parent interrupt controller, such as GIC in case of Exynos4210.
+
+ The interrupt combiner controller consists of multiple combiners. Up to eight
+ interrupt sources can be connected to a combiner. The combiner outputs one
+ combined interrupt for its eight interrupt sources. The combined interrupt is
+ usually connected to a parent interrupt controller.
+
+ A single node in the device tree is used to describe the interrupt combiner
+ controller module (which includes multiple combiners). A combiner in the
+ interrupt controller module shares config/control registers with other
+ combiners. For example, a 32-bit interrupt enable/disable config register can
+ accommodate up to 4 interrupt combiners (with each combiner supporting up to
+ 8 interrupt sources).

+title: SiFive Platform-Level Interrupt Controller (PLIC)
+
+description:
+ SiFive SoCs and other RISC-V SoCs include an implementation of the
+ Platform-Level Interrupt Controller (PLIC) high-level specification in
+ the RISC-V Privileged Architecture specification. The PLIC connects all
+ external interrupts in the system to all hart contexts in the system, via
+ the external interrupt source in each hart.
+
+ A hart context is a privilege mode in a hardware execution thread. For example,
+ in an 4 core system with 2-way SMT, you have 8 harts and probably at least two
+ privilege modes per hart; machine mode and supervisor mode.
+
+ Each interrupt can be enabled on per-context basis. Any context can claim
+ a pending enabled interrupt and then release it once it has been handled.
+
+ Each interrupt has a configurable priority. Higher priority interrupts are
+ serviced first. Each context can specify a priority threshold. Interrupts
+ with priority below this threshold will not cause the PLIC to raise its
+ interrupt line leading to the context.
+
+ The PLIC supports both edge-triggered and level-triggered interrupts. For
+ edge-triggered interrupts, the RISC-V PLIC spec allows two responses to edges
+ seen while an interrupt handler is active; the PLIC may either queue them or
+ ignore them. In the first case, handlers are oblivious to the trigger type, so
+ it is not included in the interrupt specifier. In the second case, software
+ needs to know the trigger type, so it can reorder the interrupt flow to avoid
+ missing interrupts. This special handling is needed by at least the Renesas
+ RZ/Five SoC (AX45MP AndesCore with a NCEPLIC100) and the T-HEAD C900 PLIC.
+
+ While the RISC-V ISA doesn't specify a memory layout for the PLIC, the
+ "sifive,plic-1.0.0" device is a concrete implementation of the PLIC that
+ contains a specific memory layout, which is documented in chapter 8 of the
+ SiFive U5 Coreplex Series Manual <https://static.dev.sifive.com/U54-MC-RVCoreIP.pdf>.
+
+ The thead,c900-plic is different from sifive,plic-1.0.0 in opensbi, the
+ T-HEAD PLIC implementation requires setting a delegation bit to allow access
+ from S-mode. So add thead,c900-plic to distinguish them.

+ Value of the first cell specifies the "common" IRQ from peripheral to IDU.
+ Number N of the particular interrupt line of IDU corresponds to the line N+24
+ of the core interrupt controller.
+
+ The (optional) second cell specifies any of the following flags:
+ - bits[3:0] trigger type and level flags
+ 1 = low-to-high edge triggered
+ 2 = NOT SUPPORTED (high-to-low edge triggered)
+ 4 = active high level-sensitive <<< DEFAULT
+ 8 = NOT SUPPORTED (active low level-sensitive)
+ When no second cell is specified, the interrupt is assumed to be level
+ sensitive.
+
+ The interrupt controller is accessed via the special ARC AUX register
+ interface, hence "reg" property is not specified.
+

+Synopsys DesignWare APB interrupt controller (dw_apb_ictl)
+
+Synopsys DesignWare provides interrupt controller IP for APB known as
+dw_apb_ictl. The IP is used as secondary interrupt controller in some SoCs with
+APB bus, e.g. Marvell Armada 1500. It can also be used as primary interrupt
+controller in some SoCs, e.g. Hisilicon SD5203.
+
+Required properties:
+- compatible: shall be "snps,dw-apb-ictl"
+- reg: physical base address of the controller and length of memory mapped
+ region starting with ENABLE_LOW register
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: number of cells to encode an interrupt-specifier, shall be 1
+
+Additional required property when it's used as secondary interrupt controller:
+- interrupts: interrupt reference to primary interrupt controller
+
+The interrupt sources map to the corresponding bits in the interrupt
+registers, i.e.
+- 0 maps to bit 0 of low interrupts,
+- 1 maps to bit 1 of low interrupts,
+- 32 maps to bit 0 of high interrupts,
+- 33 maps to bit 1 of high interrupts,
+- (optional) fast interrupts start at 64.

+* SPEAr Shared IRQ layer (shirq)
+
+SPEAr3xx architecture includes shared/multiplexed irqs for certain set
+of devices. The multiplexor provides a single interrupt to parent
+interrupt controller (VIC) on behalf of a group of devices.
+
+There can be multiple groups available on SPEAr3xx variants but not
+exceeding 4. The number of devices in a group can differ, further they
+may share same set of status/mask registers spanning across different
+bit masks. Also in some cases the group may not have enable or other
+registers. This makes software little complex.
+
+A single node in the device tree is used to describe the shared
+interrupt multiplexor (one node for all groups). A group in the
+interrupt controller shares config/control registers with other groups.
+For example, a 32-bit interrupt enable/disable config register can
+accommodate up to 4 interrupt groups.
+
+Required properties:
+ - compatible: should be, either of
+ - "st,spear300-shirq"
+ - "st,spear310-shirq"
+ - "st,spear320-shirq"
+ - interrupt-controller: Identifies the node as an interrupt controller.
+ - #interrupt-cells: should be <1> which basically contains the offset
+ (starting from 0) of interrupts for all the groups.
+ - reg: Base address and size of shirq registers.
+ - interrupts: The list of interrupts generated by the groups which are
+ then connected to a parent interrupt controller. Each group is
+ associated with one of the interrupts, hence number of interrupts (to
+ parent) is equal to number of groups. The format of the interrupt
+ specifier depends in the interrupt parent controller.
+
+Example:
+
+The following is an example from the SPEAr320 SoC dtsi file.
+
+shirq: interrupt-controller@b3000000 {
+ compatible = "st,spear320-shirq";
+ reg = <0xb3000000 0x1000>;
+ interrupts = <28 29 30 1>;

+TI OMAP4 Wake-up Generator
+
+All TI OMAP4/5 (and their derivatives) an interrupt controller that
+routes interrupts to the GIC, and also serves as a wakeup source. It
+is also referred to as "WUGEN-MPU", hence the name of the binding.
+
+Required properties:
+
+- compatible : should contain at least "ti,omap4-wugen-mpu" or
+ "ti,omap5-wugen-mpu"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value must be 3.
+
+Notes:
+
+- Because this HW ultimately routes interrupts to the GIC, the
+ interrupt specifier must be that of the GIC.
+- Only SPIs can use the WUGEN as an interrupt parent. SGIs and PPIs
+ are explicitly forbidden.
+
+Example:
+
+ wakeupgen: interrupt-controller@48281000 {
+ compatible = "ti,omap5-wugen-mpu", "ti,omap4-wugen-mpu";
+ interrupt-controller;
+ #interrupt-cells = <3>;
+ reg = <0x48281000 0x1000>;
+ interrupt-parent = <&gic>;

+
+description: |
+ Each PRU-ICSS has a single interrupt controller instance that is common
+ to all the PRU cores. Most interrupt controllers can route 64 input events
+ which are then mapped to 10 possible output interrupts through two levels
+ of mapping. The input events can be triggered by either the PRUs and/or
+ various other PRUSS internal and external peripherals. The first 2 output
+ interrupts (0, 1) are fed exclusively to the internal PRU cores, with the
+ remaining 8 (2 through 9) connected to external interrupt controllers
+ including the MPU and/or other PRUSS instances, DSPs or devices.
+
+ The property "ti,irqs-reserved" is used for denoting the connection
+ differences on the output interrupts 2 through 9. If this property is not
+ defined, it implies that all the PRUSS INTC output interrupts 2 through 9
+ (host_intr0 through host_intr7) are connected exclusively to the Arm interrupt
+ controller.
+
+ The K3 family of SoCs can handle 160 input events that can be mapped to 20
+ different possible output interrupts. The additional output interrupts (10
+ through 19) are connected to new sub-modules within the ICSSG instances.
+
+ This interrupt-controller node should be defined as a child node of the
+ corresponding PRUSS node. The node should be named "interrupt-controller".

+description:
+ Apple SART is a simple address filter for DMA transactions. Regions of
+ physical memory must be added to the SART's allow list before any
+ DMA can target these. Unlike a proper IOMMU no remapping can be done and
+ special support in the consumer driver is required since not all DMA
+ transactions of a single device are subject to SART filtering.
+
+ SART1 has first been used since at least the A11 (iPhone 8 and iPhone X)
+ and allows 36 bit of physical address space and filter entries with sizes
+ up to 24 bit.
+
+ SART2, first seen in A14 and M1, allows 36 bit of physical address space
+ and filter entry size up to 36 bit.

+This document describes the generic device tree binding for IOMMUs and their
+master(s).
+
+
+IOMMU device node:
+==================
+
+An IOMMU can provide the following services:
+
+* Remap address space to allow devices to access physical memory ranges that
+ they otherwise wouldn't be capable of accessing.
+
+ Example: 32-bit DMA to 64-bit physical addresses
+
+* Implement scatter-gather at page level granularity so that the device does
+ not have to.
+
+* Provide system protection against "rogue" DMA by forcing all accesses to go
+ through the IOMMU and faulting when encountering accesses to unmapped
+ address regions.
+
+* Provide address space isolation between multiple contexts.
+
+ Example: Virtualization
+
+Device nodes compatible with this binding represent hardware with some of the
+above capabilities.
+
+IOMMUs can be single-master or multiple-master. Single-master IOMMU devices
+typically have a fixed association to the master device, whereas multiple-
+master IOMMU devices can translate accesses from more than one master.
+
+The device tree node of the IOMMU device's parent bus must contain a valid
+"dma-ranges" property that describes how the physical address space of the
+IOMMU maps to memory. An empty "dma-ranges" property means that there is a
+1:1 mapping from IOMMU to memory.
+
+Required properties:
+--------------------
+- #iommu-cells: The number of cells in an IOMMU specifier needed to encode an
+ address.
+
+The meaning of the IOMMU specifier is defined by the device tree binding of
+the specific IOMMU. Below are a few examples of typical use-cases:
+
+- #iommu-cells = <0>: Single master IOMMU devices are not configurable and
+ therefore no additional information needs to be encoded in the specifier.
+ This may also apply to multiple master IOMMU devices that do not allow the
+ association of masters to be configured. Note that an IOMMU can by design
+ be multi-master yet only expose a single master in a given configuration.
+ In such cases the number of cells will usually be 1 as in the next case.
+- #iommu-cells = <1>: Multiple master IOMMU devices may need to be configured
+ in order to enable translation for a given master. In such cases the single
+ address cell corresponds to the master device's ID. In some cases more than
+ one cell can be required to represent a single master ID.
+- #iommu-cells = <4>: Some IOMMU devices allow the DMA window for masters to
+ be configured. The first cell of the address in this may contain the master
+ device's ID for example, while the second cell could contain the start of
+ the DMA window for the given device. The length of the DMA window is given
+ by the third and fourth cells.
+
+Note that these are merely examples and real-world use-cases may use different
+definitions to represent their individual needs. Always refer to the specific
+IOMMU binding for the exact meaning of the cells that make up the specifier.
+
+
+IOMMU master node:
+==================
+
+Devices that access memory through an IOMMU are called masters. A device can
+have multiple master interfaces (to one or more IOMMU devices).
+
+Required properties:
+--------------------
+- iommus: A list of phandle and IOMMU specifier pairs that describe the IOMMU
+ master interfaces of the device. One entry in the list describes one master
+ interface of the device.
+
+When an "iommus" property is specified in a device tree node, the IOMMU will
+be used for address translation. If a "dma-ranges" property exists in the
+device's parent node it will be ignored. An exception to this rule is if the
+referenced IOMMU is disabled, in which case the "dma-ranges" property of the
+parent shall take effect. Note that merely disabling a device tree node does
+not guarantee that the IOMMU is really disabled since the hardware may not
+have a means to turn off translation. But it is invalid in such cases to
+disable the IOMMU's device tree node in the first place because it would
+prevent any driver from properly setting up the translations.
+
+Optional properties:
+--------------------
+- pasid-num-bits: Some masters support multiple address spaces for DMA, by
+ tagging DMA transactions with an address space identifier. By default,
+ this is 0, which means that the device only has one address space.
+
+- dma-can-stall: When present, the master can wait for a transaction to
+ complete for an indefinite amount of time. Upon translation fault some
+ IOMMUs, instead of aborting the translation immediately, may first
+ notify the driver and keep the transaction in flight. This allows the OS
+ to inspect the fault and, for example, make physical pages resident
+ before updating the mappings and completing the transaction. Such IOMMU
+ accepts a limited number of simultaneous stalled transactions before
+ having to either put back-pressure on the master, or abort new faulting
+ transactions.
+
+ Firmware has to opt-in stalling, because most buses and masters don't
+ support it. In particular it isn't compatible with PCI, where
+ transactions have to complete before a time limit. More generally it
+ won't work in systems and masters that haven't been designed for
+ stalling. For example the OS, in order to handle a stalled transaction,
+ may attempt to retrieve pages from secondary storage in a stalled
+ domain, leading to a deadlock.
+
+
+Notes:
+======
+
+One possible extension to the above is to use an "iommus" property along with
+a "dma-ranges" property in a bus device node (such as PCI host bridges). This
+can be useful to describe how children on the bus relate to the IOMMU if they
+are not explicitly listed in the device tree (e.g. PCI devices). However, the
+requirements of that use-case haven't been fully determined yet. Implementing
+this is therefore not recommended without further discussion and extension of
+this binding.
+
+
+Examples:
+=========
+
+Single-master IOMMU:
+--------------------
+
+ iommu {
+ #iommu-cells = <0>;
+ };
+
+ master {
+ iommus = <&{/iommu}>;
+ };
+
+Multiple-master IOMMU with fixed associations:
+----------------------------------------------
+
+ /* multiple-master IOMMU */
+ iommu {
+ /*
+ * Masters are statically associated with this IOMMU and share
+ * the same address translations because the IOMMU does not
+ * have sufficient information to distinguish between masters.
+ *
+ * Consequently address translation is always on or off for
+ * all masters at any given point in time.
+ */
+ #iommu-cells = <0>;
+ };
+
+ /* static association with IOMMU */
+ master@1 {
+ reg = <1>;
+ iommus = <&{/iommu}>;
+ };
+
+ /* static association with IOMMU */
+ master@2 {
+ reg = <2>;
+ iommus = <&{/iommu}>;
+ };
+
+Multiple-master IOMMU:
+----------------------
+
+ iommu {
+ /* the specifier represents the ID of the master */
+ #iommu-cells = <1>;
+ };
+
+ master@1 {
+ /* device has master ID 42 in the IOMMU */
+ iommus = <&{/iommu} 42>;
+ };
+
+ master@2 {
+ /* device has master IDs 23 and 24 in the IOMMU */
+ iommus = <&{/iommu} 23>, <&{/iommu} 24>;
+ };
+
+Multiple-master IOMMU with configurable DMA window:
+---------------------------------------------------
+
+ / {
+ iommu {
+ /*
+ * One cell for the master ID and one cell for the
+ * address of the DMA window. The length of the DMA
+ * window is encoded in two cells.
+ *
+ * The DMA window is the range addressable by the
+ * master (i.e. the I/O virtual address space).
+ */
+ #iommu-cells = <4>;
+ };
+
+ master {
+ /* master ID 42, 4 GiB DMA window starting at 0 */
+ iommus = <&{/iommu} 42 0 0x1 0x0>;
+ };
+ };

+description: |+
+ Some MediaTek SOCs contain a Multimedia Memory Management Unit (M4U), and
+ this M4U have two generations of HW architecture. Generation one uses flat
+ pagetable, and only supports 4K size page mapping. Generation two uses the
+ ARM Short-Descriptor translation table format for address translation.
+
+ About the M4U Hardware Block Diagram, please check below:
+
+ EMI (External Memory Interface)
+ |
+ m4u (Multimedia Memory Management Unit)
+ |
+ +--------+
+ | |
+ gals0-rx gals1-rx (Global Async Local Sync rx)
+ | |
+ | |
+ gals0-tx gals1-tx (Global Async Local Sync tx)
+ | | Some SoCs may have GALS.
+ +--------+
+ |
+ SMI Common(Smart Multimedia Interface Common)
+ |
+ +----------------+-------
+ | |
+ | gals-rx There may be GALS in some larbs.
+ | |
+ | |
+ | gals-tx
+ | |
+ SMI larb0 SMI larb1 ... SoCs have several SMI local arbiter(larb).
+ (display) (vdec)
+ | |
+ | |
+ +-----+-----+ +----+----+
+ | | | | | |
+ | | |... | | | ... There are different ports in each larb.
+ | | | | | |
+ OVL0 RDMA0 WDMA0 MC PP VLD
+
+ As above, The Multimedia HW will go through SMI and M4U while it
+ access EMI. SMI is a bridge between m4u and the Multimedia HW. It contain
+ smi local arbiter and smi common. It will control whether the Multimedia
+ HW should go though the m4u for translation or bypass it and talk
+ directly with EMI. And also SMI help control the power domain and clocks for
+ each local arbiter.
+
+ Normally we specify a local arbiter(larb) for each multimedia HW
+ like display, video decode, and camera. And there are different ports
+ in each larb. Take a example, There are many ports like MC, PP, VLD in the
+ video decode local arbiter, all these ports are according to the video HW.
+
+ In some SoCs, there may be a GALS(Global Async Local Sync) module between
+ smi-common and m4u, and additional GALS module between smi-larb and
+ smi-common. GALS can been seen as a "asynchronous fifo" which could help
+ synchronize for the modules in different clock frequency.

+* QCOM IOMMU
+
+The MSM IOMMU is an implementation compatible with the ARM VMSA short
+descriptor page tables. It provides address translation for bus masters outside
+of the CPU, each connected to the IOMMU through a port called micro-TLB.
+
+Required Properties:
+
+ - compatible: Must contain "qcom,apq8064-iommu".
+ - reg: Base address and size of the IOMMU registers.
+ - interrupts: Specifiers for the MMU fault interrupts. For instances that
+ support secure mode two interrupts must be specified, for non-secure and
+ secure mode, in that order. For instances that don't support secure mode a
+ single interrupt must be specified.
+ - #iommu-cells: The number of cells needed to specify the stream id. This
+ is always 1.
+ - qcom,ncb: The total number of context banks in the IOMMU.
+ - clocks : List of clocks to be used during SMMU register access. See
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ for information about the format. For each clock specified
+ here, there must be a corresponding entry in clock-names
+ (see below).
+
+ - clock-names : List of clock names corresponding to the clocks specified in
+ the "clocks" property (above).
+ Should be "smmu_pclk" for specifying the interface clock
+ required for iommu's register accesses.
+ Should be "smmu_clk" for specifying the functional clock
+ required by iommu for bus accesses.
+
+Each bus master connected to an IOMMU must reference the IOMMU in its device
+node with the following property:
+
+ - iommus: A reference to the IOMMU in multiple cells. The first cell is a
+ phandle to the IOMMU and the second cell is the stream id.
+ A single master device can be connected to more than one iommu
+ and multiple contexts in each of the iommu. So multiple entries
+ are required to list all the iommus and the stream ids that the
+ master is connected to.
+
+Example: mdp iommu and its bus master
+
+ mdp_port0: iommu@7500000 {
+ compatible = "qcom,apq8064-iommu";
+ #iommu-cells = <1>;

+
+maintainers:

+
+description: |+
+ Samsung's Exynos architecture contains System MMUs that enables scattered
+ physical memory chunks visible as a contiguous region to DMA-capable peripheral
+ devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
+
+ System MMU is an IOMMU and supports identical translation table format to
+ ARMv7 translation tables with minimum set of page properties including access
+ permissions, shareability and security protection. In addition, System MMU has
+ another capabilities like L2 TLB or block-fetch buffers to minimize translation
+ latency.
+
+ System MMUs are in many to one relation with peripheral devices, i.e. single
+ peripheral device might have multiple System MMUs (usually one for each bus
+ master), but one System MMU can handle transactions from only one peripheral
+ device. The relation between a System MMU and the peripheral device needs to be
+ defined in device node of the peripheral device.
+
+ MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
+ MMUs.
+ * MFC has one System MMU on its left and right bus.
+ * FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
+ for window 1, 2 and 3.
+ * M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
+ the other System MMU on the write channel.
+
+ For information on assigning System MMU controller to its peripheral devices,
+ see generic IOMMU bindings.

+description:
+ LED and flash LED devices provide the same basic functionality as current
+ regulators, but extended with LED and flash LED specific features like
+ blinking patterns, flash timeout, flash faults and external flash strobe mode.
+
+ Many LED devices expose more than one current output that can be connected
+ to one or more discrete LED component. Since the arrangement of connections
+ can influence the way of the LED device initialization, the LED components
+ have to be tightly coupled with the LED device binding. They are represented
+ by child nodes of the parent LED device binding.
+
+properties:
+ led-sources:

+ Another common example is switch or router with multiple Ethernet ports
+ each of them having its own LED assigned (assuming they are not
+ hardwired). In such cases this property should contain phandle(s) of
+ related source device(s).
+ In many cases LED can be related to more than one device (e.g. one USB LED
+ vs. multiple USB ports). Each source should be represented by a node in

+maintainers:

+
+description: |
+ This controller is present on BCM6318, BCM6328, BCM6362 and BCM63268.
+ In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
+ However, on some devices there are Serial LEDs (LEDs connected to a 74x164
+ controller), which can either be controlled by software (exporting the 74x164
+ as spi-gpio. See
+ Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or by hardware
+ using this driver.
+ Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
+ exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
+ controlled, so the only chance to keep them working is by using this driver.
+
+ BCM6328 LED controller has a HWDIS register, which controls whether a LED
+ should be controlled by a hardware signal instead of the MODE register value,
+ with 0 meaning hardware control enabled and 1 hardware control disabled. This
+ is usually 1:1 for hardware to LED signals, but through the activity/link
+ registers you have some limited control over rerouting the LEDs (as
+ explained later in brcm,link-signal-sources). Even if a LED is hardware
+ controlled you are still able to make it blink or light it up if it isn't,
+ but you can't turn it off if the hardware decides to light it up. For this
+ reason, hardware controlled LEDs aren't registered as LED class devices.
+
+ Each LED is represented as a sub-node of the brcm,bcm6328-leds device.

+LEDs connected to Broadcom BCM6358 controller
+
+This controller is present on BCM6358 and BCM6368.
+In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
+which can either be controlled by software (exporting the 74x164 as spi-gpio.
+See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
+by hardware using this driver.
+
+Required properties:
+ - compatible : should be "brcm,bcm6358-leds".
+ - #address-cells : must be 1.
+ - #size-cells : must be 0.
+ - reg : BCM6358 LED controller address and size.
+
+Optional properties:
+ - brcm,clk-div : SCK signal divider. Possible values are 1, 2, 4 and 8.
+ Default : 1
+ - brcm,clk-dat-low : Boolean, makes clock and data signals active low.
+ Default : false
+
+Each LED is represented as a sub-node of the brcm,bcm6358-leds device.
+
+LED sub-node required properties:
+ - reg : LED pin number (only LEDs 0 to 31 are valid).
+
+LED sub-node optional properties:
+ - label : see Documentation/devicetree/bindings/leds/common.txt

+* Texas Instruments - lm3532 White LED driver with ambient light sensing
+capability.
+
+The LM3532 provides the 3 high-voltage, low-side current sinks. The device is
+programmable over an I2C-compatible interface and has independent
+current control for all three channels. The adaptive current regulation
+method allows for different LED currents in each current sink thus allowing
+for a wide variety of backlight and keypad applications.
+
+The main features of the LM3532 include dual ambient light sensor inputs
+each with 32 internal voltage setting resistors, 8-bit logarithmic and linear
+brightness control, dual external PWM brightness control inputs, and up to
+1000:1 dimming ratio with programmable fade in and fade out settings.
+
+Required properties:
+ - compatible : "ti,lm3532"
+ - reg : I2C slave address
+ - #address-cells : 1
+ - #size-cells : 0
+
+Optional properties:
+ - enable-gpios : gpio pin to enable (active high)/disable the device.
+ - ramp-up-us - The Run time ramp rates/step are from one current
+ set-point to another after the device has reached its
+ initial target set point from turn-on
+ - ramp-down-us - The Run time ramp rates/step are from one current
+ set-point to another after the device has reached its
+ initial target set point from turn-on
+ Range for ramp settings: 8us - 65536us
+

+ - ti,als-vmin - Minimum ALS voltage defined in Volts
+ - ti,als-vmax - Maximum ALS voltage defined in Volts
+ Per the data sheet the max ALS voltage is 2V and the min is 0V
+
+ - ti,als1-imp-sel - ALS1 impedance resistor selection in Ohms
+ - ti,als2-imp-sel - ALS2 impedance resistor selection in Ohms
+ Range for impedance select: 37000 Ohms - 1190 Ohms
+ Values above 37kohms will be set to the "High Impedance" setting
+
+ - ti,als-avrg-time-us - Determines the length of time the device needs to
+ average the two ALS inputs. This is only used if
+ the input mode is LM3532_ALS_INPUT_AVRG.
+ Range: 17920us - 2293760us
+ - ti,als-input-mode - Determines how the device uses the attached ALS
+ devices.

+* Single Byte SPI LED Device Driver.
+
+The driver can be used for controllers with a very simple SPI protocol:
+- one LED is controlled by a single byte on MOSI
+- the value of the byte gives the brightness between two values (lowest to
+ highest)
+- no return value is necessary (no MISO signal)
+
+The value for lowest and highest brightness is dependent on the device and
+therefore on the compatible string.
+
+Depending on the compatible string some special functions (like hardware
+accelerated blinking) might can be supported too.
+
+The driver currently only supports one LED. The properties of the LED are
+configured in a sub-node in the device node.
+
+Required properties:
+- compatible: should be one of
+ * "ubnt,acb-spi-led" microcontroller (SONiX 8F26E611LA) based device

+* Pattern format for LED pattern trigger
+
+The pattern is given by a series of tuples, of brightness and duration (ms).
+The LED is expected to traverse the series and each brightness value for the
+specified duration. Duration of 0 means brightness should immediately change to
+new value, and writing malformed pattern deactivates any active one.
+
+1. For gradual dimming, the dimming interval now is set as 50 milliseconds. So
+the tuple with duration less than dimming interval (50ms) is treated as a step
+change of brightness, i.e. the subsequent brightness will be applied without
+adding intervening dimming intervals.
+
+The gradual dimming format of the software pattern values should be:
+"brightness_1 duration_1 brightness_2 duration_2 brightness_3 duration_3 ...".
+For example (using sysfs interface):
+
+echo 0 1000 255 2000 > pattern
+
+It will make the LED go gradually from zero-intensity to max (255) intensity in
+1000 milliseconds, then back to zero intensity in 2000 milliseconds:
+
+LED brightness
+ ^
+255-| / \ / \ /
+ | / \ / \ /
+ | / \ / \ /
+ | / \ / \ /
+ 0-| / \/ \/
+ +---0----1----2----3----4----5----6------------> time (s)
+
+2. To make the LED go instantly from one brightness value to another, we should
+use zero-time lengths (the brightness must be same as the previous tuple's). So
+the format should be: "brightness_1 duration_1 brightness_1 0 brightness_2
+duration_2 brightness_2 0 ...".
+For example (using sysfs interface):
+
+echo 0 1000 0 0 255 2000 255 0 > pattern
+
+It will make the LED stay off for one second, then stay at max brightness for
+two seconds:

+description: |
+ The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has 3
+ independent channels/links to communicate with remote processor(s). MHU links
+ are hardwired on a platform. A link raises interrupt for any received data.
+ However, there is no specified way of knowing if the sent data has been read
+ by the remote. This driver assumes the sender polls STAT register and the
+ remote clears it after having read the data. The last channel is specified to
+ be a 'Secure' resource, hence can't be used by Linux running NS.
+
+ The MHU hardware also allows operations in doorbell mode. The MHU drives the
+ interrupt signal using a 32-bit register, with all 32-bits logically ORed
+ together. It provides a set of registers to enable software to set, clear and
+ check the status of each of the bits of this register independently. The use
+ of 32 bits per interrupt line enables software to provide more information
+ about the source of the interrupt. For example, each bit of the register can
+ be associated with a type of event that can contribute to raising the
+ interrupt. Each of the 32-bits can be used as "doorbell" to alert the remote
+ processor.

+description: |
+ The Arm Message Handling Unit (MHU) Version 2 is a mailbox controller that has
+ between 1 and 124 channel windows (each 32-bit wide) to provide unidirectional
+ communication with remote processor(s), where the number of channel windows
+ are implementation dependent.
+
+ Given the unidirectional nature of the controller, an MHUv2 mailbox may only
+ be written to or read from. If a pair of MHU controllers is implemented
+ between two processing elements to provide bidirectional communication, these
+ must be specified as two separate mailboxes.
+
+ If the interrupts property is present in device tree node, then its treated as
+ a "receiver" mailbox, otherwise a "sender".
+
+ An MHU controller must be specified along with the supported transport
+ protocols. The transport protocols determine the method of data transmission
+ as well as the number of provided mailbox channels.
+
+ Following are the possible transport protocols.
+
+ - Data-transfer: Each transfer is made of one or more words, using one or more
+ channel windows.
+
+ - Doorbell: Each transfer is made up of single bit flag, using any one of the
+ bits in a channel window. A channel window can support up to 32 doorbells
+ and the entire window shall be used in doorbell protocol. Optionally, data
+ may be transmitted through a shared memory region, wherein the MHU is used
+ strictly as an interrupt generation mechanism but that is out of the scope
+ of these bindings.

+
+ The first field of a tuple signifies the transfer protocol, 0 is reserved
+ for doorbell protocol, and 1 is reserved for data-transfer protocol.
+ Using any other value in the first field of a tuple makes it invalid.
+
+ The second field of a tuple signifies the number of channel windows where
+ the protocol would be used and should be set to a non zero value. For
+ doorbell protocol this field signifies the number of 32-bit channel
+ windows that implement the doorbell protocol. For data-transfer protocol,
+ this field signifies the number of 32-bit channel windows that implement
+ the data-transfer protocol.

+Broadcom FlexRM Ring Manager
+============================
+The Broadcom FlexRM ring manager provides a set of rings which can be
+used to submit work to offload engines. An SoC may have multiple FlexRM
+hardware blocks. There is one device tree entry per FlexRM block. The
+FlexRM driver will create a mailbox-controller instance for given FlexRM
+hardware block where each mailbox channel is a separate FlexRM ring.
+
+Required properties:
+--------------------
+- compatible: Should be "brcm,iproc-flexrm-mbox"
+- reg: Specifies base physical address and size of the FlexRM
+ ring registers
+- msi-parent: Phandles (and potential Device IDs) to MSI controllers
+ The FlexRM engine will send MSIs (instead of wired
+ interrupts) to CPU. There is one MSI for each FlexRM ring.
+ Refer devicetree/bindings/interrupt-controller/msi.txt
+- #mbox-cells: Specifies the number of cells needed to encode a mailbox
+ channel. This should be 3.
+
+ The 1st cell is the mailbox channel number.
+
+ The 2nd cell contains MSI completion threshold. This is the
+ number of completion messages for which FlexRM will inject
+ one MSI interrupt to CPU.
+
+ The 3nd cell contains MSI timer value representing time for
+ which FlexRM will wait to accumulate N completion messages
+ where N is the value specified by 2nd cell above. If FlexRM
+ does not get required number of completion messages in time
+ specified by this cell then it will inject one MSI interrupt
+ to CPU provided at least one completion message is available.
+
+Optional properties:
+--------------------
+- dma-coherent: Present if DMA operations made by the FlexRM engine (such
+ as DMA descriptor access, access to buffers pointed by DMA
+ descriptors and read/write pointer updates to DDR) are
+ cache coherent with the CPU.
+
+Example:
+--------
+crypto_mbox: mbox@67000000 {
+ compatible = "brcm,iproc-flexrm-mbox";
+ reg = <0x67000000 0x200000>;

+
+description: |
+ The Messaging Unit module enables two processors within the SoC to
+ communicate and coordinate by passing messages (e.g. data, status
+ and control) through the MU interface. The MU also provides the ability
+ for one processor to signal the other processor using interrupts.
+
+ Because the MU manages the messaging between processors, the MU uses
+ different clocks (from each side of the different peripheral buses).
+ Therefore, the MU must synchronize the accesses from one side to the
+ other. The MU accomplishes synchronization using two sets of matching
+ registers (Processor A-facing, Processor B-facing).

+Hisilicon Hi6220 Mailbox Driver
+===============================
+
+Hisilicon Hi6220 mailbox supports up to 32 channels. Each channel
+is unidirectional with a maximum message size of 8 words. I/O is
+performed using register access (there is no DMA) and the cell
+raises an interrupt when messages are received.
+
+Mailbox Device Node:
+====================
+
+Required properties:
+--------------------
+- compatible: Shall be "hisilicon,hi6220-mbox"
+- reg: Contains the mailbox register address range (base
+ address and length); the first item is for IPC
+ registers, the second item is shared buffer for
+ slots.
+- #mbox-cells: Common mailbox binding property to identify the number
+ of cells required for the mailbox specifier. Must be 3.
+ <&phandle slot_id dst_irq ack_irq>
+ phandle: Label name of mailbox controller
+ slot_id: Slot id used either for TX or RX
+ dst_irq: IRQ identifier index number which used by MCU
+ ack_irq: IRQ identifier index number with generating a
+ TX/RX interrupt to application processor,
+ mailbox driver uses it to acknowledge interrupt
+- interrupts: Contains the interrupt information for the mailbox
+ device. The format is dependent on which interrupt
+ controller the SoCs use.
+
+Optional Properties:
+--------------------
+- hi6220,mbox-tx-noirq: Property of MCU firmware's feature, so mailbox driver
+ use this flag to ask MCU to enable "automatic idle
+ flag" mode or IRQ generated mode to acknowledge a TX
+ completion.
+
+Example:
+--------
+
+ mailbox: mailbox@f7510000 {
+ compatible = "hisilicon,hi6220-mbox";
+ reg = <0x0 0xf7510000 0x0 0x1000>, /* IPC_S */

+title: NVIDIA Tegra Hardware Synchronization Primitives (HSP)
+
+maintainers:
+ - Thierry Reding <thierry.reding@gmail.com>
+ - Jon Hunter <jonathanh@nvidia.com>
+
+description: |
+ The HSP modules are used for the processors to share resources and
+ communicate together. It provides a set of hardware synchronization
+ primitives for interprocessor communication. So the interprocessor
+ communication (IPC) protocols can use hardware synchronization
+ primitives, when operating between two processors not in an SMP
+ relationship.
+
+ The features that HSP supported are shared mailboxes, shared
+ semaphores, arbitrated semaphores and doorbells.
+
+ The mbox specifier of the "mboxes" property in the client node should
+ contain two cells. The first cell determines the HSP type and the
+ second cell is used to identify the mailbox that the client is going
+ to use.
+
+ For shared mailboxes, the first cell composed of two fields:
+ - bits 15..8:
+ A bit mask of flags that further specifies the type of shared
+ mailbox to be used (based on the data size). If no flag is
+ specified then, 32-bit shared mailbox is used.
+ - bits 7..0:
+ Defines the type of the mailbox to be used. This field should be
+ TEGRA_HSP_MBOX_TYPE_SM for shared mailboxes.
+
+ For doorbells, the second cell specifies the index of the doorbell to
+ use.
+
+ For shared mailboxes, the second cell is composed of two fields:
+ - bits 31..24:
+ A bit mask of flags that further specify how the shared mailbox
+ will be used. Valid flags are:
+ - bit 31:
+ Defines the direction of the mailbox. If set, the mailbox
+ will be used as a producer (i.e. used to send data). If
+ cleared, the mailbox is the consumer of data sent by a
+ producer.
+
+ - bits 23..0:
+ The index of the shared mailbox to use. The number of available
+ mailboxes may vary by instance of the HSP block and SoC
+ generation.
+
+ The following file contains definitions that can be used to
+ construct mailbox specifiers:

+Texas Instruments' Message Manager Driver
+========================================
+
+The Texas Instruments' Message Manager is a mailbox controller that has
+configurable queues selectable at SoC(System on Chip) integration. The Message
+manager is broken up into queues in different address regions that are called
+"proxies" - each instance is unidirectional and is instantiated at SoC
+integration level to indicate receive or transmit path.
+
+Message Manager Device Node:
+===========================
+Required properties:
+--------------------
+- compatible: Shall be: "ti,k2g-message-manager"
+- reg-names queue_proxy_region - Map the queue proxy region.
+ queue_state_debug_region - Map the queue state debug
+ region.
+- reg: Contains the register map per reg-names.
+- #mbox-cells Shall be 2. Contains the queue ID and proxy ID in that
+ order referring to the transfer path.
+- interrupt-names: Contains interrupt names matching the rx transfer path
+ for a given SoC. Receive interrupts shall be of the
+ format: "rx_<QID>".
+ For ti,k2g-message-manager, this shall contain:
+ "rx_005", "rx_057"
+- interrupts: Contains the interrupt information corresponding to
+ interrupt-names property.
+
+Example(K2G):
+------------
+
+ msgmgr: msgmgr@2a00000 {
+ compatible = "ti,k2g-message-manager";
+ #mbox-cells = <2>;
+ reg-names = "queue_proxy_region", "queue_state_debug_region";

+
+maintainers:
+ - Suman Anna <s-anna@ti.com>
+
+description: |
+ The OMAP Mailbox hardware facilitates communication between different
+ processors using a queued mailbox interrupt mechanism. The IP block is
+ external to the various processor subsystems and is connected on an
+ interconnect bus. The communication is achieved through a set of registers
+ for message storage and interrupt configuration registers.
+
+ Each mailbox IP block/cluster has a certain number of h/w fifo queues and
+ output interrupt lines. An output interrupt line is routed to an interrupt
+ controller within a processor subsystem, and there can be more than one line
+ going to a specific processor's interrupt controller. The interrupt line
+ connections are fixed for an instance and are dictated by the IP integration
+ into the SoC (excluding the SoCs that have an Interrupt Crossbar or an
+ Interrupt Router IP). Each interrupt line is programmable through a set of
+ interrupt configuration registers, and have a rx and tx interrupt source per
+ h/w fifo. Communication between different processors is achieved through the
+ appropriate programming of the rx and tx interrupt sources on the appropriate
+ interrupt lines.
+
+ The number of h/w fifo queues and interrupt lines dictate the usable
+ registers. All the current OMAP SoCs except for the newest DRA7xx SoC has a
+ single IP instance. DRA7xx has multiple instances with different number of
+ h/w fifo queues and interrupt lines between different instances. The interrupt
+ lines can also be routed to different processor sub-systems on DRA7xx as they
+ are routed through the Crossbar, a kind of interrupt router/multiplexer. The
+ K3 AM65x, J721E and J7200 SoCs has each of these instances form a cluster and
+ combine multiple clusters into a single IP block present within the Main
+ NavSS. The interrupt lines from all these clusters are multiplexed and routed
+ to different processor subsystems over a limited number of common interrupt
+ output lines of an Interrupt Router. The AM64x SoCS also uses a single IP
+ block comprising of multiple clusters, but the number of clusters are
+ smaller, and the interrupt output lines are connected directly to various
+ processors.
+
+ Mailbox Controller Nodes
+ =========================
+ A Mailbox device node is used to represent a Mailbox IP instance/cluster
+ within a SoC. The sub-mailboxes (actual communication channels) are
+ represented as child nodes of this parent node.
+
+ Mailbox Users
+ ==============
+ A device needing to communicate with a target processor device should specify
+ them using the common mailbox binding properties, "mboxes" and the optional
+ "mbox-names" (please see Documentation/devicetree/bindings/mailbox/mailbox.txt
+ for details). Each value of the mboxes property should contain a phandle to
+ the mailbox controller device node and an args specifier that will be the
+ phandle to the intended sub-mailbox child node to be used for communication.
+ The equivalent "mbox-names" property value can be used to give a name to the
+ communication channel to be used by the client user.

+The APM X-Gene SLIMpro mailbox is used to communicate messages between
+the ARM64 processors and the Cortex M3 (dubbed SLIMpro). It uses a simple
+interrupt based door bell mechanism and can exchange simple messages using the
+internal registers.
+
+There are total of 8 interrupts in this mailbox. Each used for an individual
+door bell (or mailbox channel).
+
+Required properties:
+- compatible: Should be as "apm,xgene-slimpro-mbox".
+
+- reg: Contains the mailbox register address range.
+
+- interrupts: 8 interrupts must be from 0 to 7, interrupt 0 define the
+ the interrupt for mailbox channel 0 and interrupt 1 for
+ mailbox channel 1 and so likewise for the reminder.
+
+- #mbox-cells: only one to specify the mailbox channel number.
+
+Example:
+
+Mailbox Node:
+ mailbox: mailbox@10540000 {
+ compatible = "apm,xgene-slimpro-mbox";
+ reg = <0x0 0x10540000 0x0 0xa000>;

+description: |
+ The video decoding IP lies within the DOS memory region,
+ except for the hardware bitstream parser that makes use of an undocumented
+ region.
+
+ It makes use of the following blocks:
+ - ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
+ then feed from this VIFIFO.
+ - VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
+ - VDEC_HEVC can decode HEVC and VP9.
+
+ Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
+ concurrently.

+Cadence MIPI-CSI2 TX controller
+===============================
+
+The Cadence MIPI-CSI2 TX controller is a CSI-2 bridge supporting up to
+4 CSI lanes in output, and up to 4 different pixel streams in input.
+
+Required properties:
+ - compatible: must be set to "cdns,csi2tx" or "cdns,csi2tx-1.3"
+ for version 1.3 of the controller, "cdns,csi2tx-2.1" for v2.1
+ - reg: base address and size of the memory mapped region
+ - clocks: phandles to the clocks driving the controller
+ - clock-names: must contain:
+ * esc_clk: escape mode clock
+ * p_clk: register bank clock
+ * pixel_if[0-3]_clk: pixel stream output clock, one for each stream
+ implemented in hardware, between 0 and 3
+
+Optional properties
+ - phys: phandle to the D-PHY. If it is set, phy-names need to be set
+ - phy-names: must contain "dphy"
+
+Required subnodes:
+ - ports: A ports node with one port child node per device input and output
+ port, in accordance with the video interface bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ port nodes are numbered as follows.
+
+ Port Description
+ -----------------------------
+ 0 CSI-2 output
+ 1 Stream 0 input
+ 2 Stream 1 input
+ 3 Stream 2 input
+ 4 Stream 3 input
+
+ The stream input port nodes are optional if they are not
+ connected to anything at the hardware level or implemented
+ in the design. Since there is only one endpoint per port,
+ the endpoints are not numbered.
+
+Example:
+
+csi2tx: csi-bridge@0d0e1000 {
+ compatible = "cdns,csi2tx";
+ reg = <0x0d0e1000 0x1000>;
+ clocks = <&byteclock>, <&byteclock>,
+ <&coreclock>, <&coreclock>,
+ <&coreclock>, <&coreclock>;
+ clock-names = "p_clk", "esc_clk",
+ "pixel_if0_clk", "pixel_if1_clk",
+ "pixel_if2_clk", "pixel_if3_clk";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ csi2tx_out: endpoint {
+ remote-endpoint = <&remote_in>;
+ clock-lanes = <0>;
+ data-lanes = <1 2>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ csi2tx_in_stream0: endpoint {
+ remote-endpoint = <&stream0_out>;
+ };
+ };
+
+ port@2 {
+ reg = <2>;
+
+ csi2tx_in_stream1: endpoint {
+ remote-endpoint = <&stream1_out>;
+ };
+ };
+
+ port@3 {
+ reg = <3>;
+
+ csi2tx_in_stream2: endpoint {
+ remote-endpoint = <&stream2_out>;
+ };
+ };
+
+ port@4 {
+ reg = <4>;
+
+ csi2tx_in_stream3: endpoint {
+ remote-endpoint = <&stream3_out>;
+ };
+ };
+ };
+};

+description:
+ The ADV7604 and ADV7610/11/12 are multiformat video decoders with
+ an integrated HDMI receiver. The ADV7604 has four multiplexed HDMI inputs
+ and one analog input, and the ADV7610/11 have one HDMI input and no analog
+ input. The ADV7612 is similar to the ADV7610/11 but has 2 HDMI inputs.
+
+ These device tree bindings support the ADV7610/11/12 only at the moment.

+description: -|
+ The IMI D&D RDACM20 and RDACM21 are GMSL-compatible camera designed for
+ automotive applications.
+
+ The RDACM20 camera module encloses a Maxim Integrated MAX9271 GMSL serializer,
+ coupled with an OV10635 image sensor and an embedded MCU. Both the MCU and
+ the image sensor are connected to the serializer local I2C bus and are
+ accessible by the host SoC by direct addressing.
+
+ The RDACM21 camera module encloses the same serializer, coupled with an
+ OV10640 image sensor and an OV490 ISP. Only the OV490 ISP is interfaced to
+ the serializer local I2C bus while the image sensor is not accessible from
+ the host SoC.
+
+ They both connect to a remote GMSL endpoint through a coaxial cable.
+

+ | | <- I2C messages -> | | |
+ | de-serializer | | OV10640 <-------| |
+ +---------------+ +--------------------------------+
+
+ Both camera modules serialize video data generated by the embedded camera
+ sensor on the GMSL serial channel to a remote GMSL de-serializer. They also
+ receive and transmit I2C messages encapsulated and transmitted on the GMSL
+ bidirectional control channel.
+
+ All I2C traffic received on the GMSL link not directed to the serializer is
+ propagated on the local I2C bus to the remote device there connected. All the
+ I2C traffic generated on the local I2C bus not directed to the serializer is
+ propagated to the remote de-serializer encapsulated in the GMSL control
+ channel.
+
+ The RDACM20 and RDACM21 DT node should be a direct child of the GMSL
+ deserializer's I2C bus corresponding to the GMSL link that the camera is
+ attached to.

+Maxim Integrated MAX2175 RF to Bits tuner
+-----------------------------------------
+
+The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with
+RF to Bits® front-end designed for software-defined radio solutions.
+
+Required properties:
+--------------------
+- compatible: "maxim,max2175" for MAX2175 RF-to-bits tuner.
+- clocks: clock specifier.
+- port: child port node corresponding to the I2S output, in accordance with
+ the video interface bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The port
+ node must contain at least one endpoint.
+
+Optional properties:
+--------------------
+- maxim,master : phandle to the master tuner if it is a slave. This
+ is used to define two tuners in diversity mode
+ (1 master, 1 slave). By default each tuner is an
+ individual master.
+- maxim,refout-load : load capacitance value (in picofarads) on reference
+ output drive level. The possible load values are:
+ 0 (default - refout disabled)
+ 10
+ 20
+ 30
+ 40
+ 60
+ 70
+- maxim,am-hiz-filter : empty property indicates the AM Hi-Z filter is used
+ in this hardware for AM antenna input.
+
+Example:
+--------
+
+Board specific DTS file
+
+/* Fixed XTAL clock node */
+maxim_xtal: clock {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <36864000>;

+ The MAX9286 deserializer receives video data on up to 4 Gigabit Multimedia
+ Serial Links (GMSL) and outputs them on a CSI-2 D-PHY port using up to 4 data
+ lanes.
+
+ In addition to video data, the GMSL links carry a bidirectional control
+ channel that encapsulates I2C messages. The MAX9286 forwards all I2C traffic

+ serializer will output it on a local I2C bus. In the other direction all I2C
+ traffic received over GMSL by the MAX9286 is output on the local I2C bus.

+
+maintainers:
+ - Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
+
+description: |
+ The MAX96712 deserializer converts GMSL2 or GMSL1 serial inputs into MIPI
+ CSI-2 D-PHY or C-PHY formatted outputs. The device allows each link to
+ simultaneously transmit bidirectional control-channel data while forward
+ video transmissions are in progress. The MAX96712 can accommodate as many as
+ four remotely located sensors using industry-standard coax or STP
+ interconnects.
+
+ Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the
+ forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the
+ MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1
+ serializers or operate up to 3.12Gbps with GMSL2 serializers in GMSL1 mode.

+ image sensors that deliver 2592x1944 at 30fps. It provides full-frame,
+ sub-sampled, and windowed 10-bit MIPI images in various formats via the
+ Serial Camera Control Bus (SCCB) interface.
+
+ OV5693/OV5695 are controlled via I2C and two-wire Serial Camera Control Bus
+ (SCCB). The sensor output is available via CSI-2 serial data output (up to

+* Toshiba TC358743 HDMI-RX to MIPI CSI2-TX Bridge
+
+The Toshiba TC358743 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts
+a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C.
+
+Required Properties:
+
+- compatible: value should be "toshiba,tc358743"
+- clocks, clock-names: should contain a phandle link to the reference clock
+ source, the clock input is named "refclk".
+
+Optional Properties:
+
+- reset-gpios: gpio phandle GPIO connected to the reset pin
+- interrupts: GPIO connected to the interrupt pin
+- data-lanes: should be <1 2 3 4> for four-lane operation,
+ or <1 2> for two-lane operation
+- clock-lanes: should be <0>
+- clock-noncontinuous: Presence of this boolean property decides whether the
+ MIPI CSI-2 clock is continuous or non-continuous.
+- link-frequencies: List of allowed link frequencies in Hz. Each frequency is
+ expressed as a 64-bit big-endian integer. The frequency
+ is half of the bps per lane due to DDR transmission.
+
+For further information on the MIPI CSI-2 endpoint node properties, see
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:

+Device-Tree bindings for the NXP TDA1997x HDMI receiver
+
+The TDA19971/73 are HDMI video receivers.
+
+The TDA19971 Video port output pins can be used as follows:
+ - RGB 8bit per color (24 bits total): R[11:4] B[11:4] G[11:4]
+ - YUV444 8bit per color (24 bits total): Y[11:4] Cr[11:4] Cb[11:4]
+ - YUV422 semi-planar 8bit per component (16 bits total): Y[11:4] CbCr[11:4]
+ - YUV422 semi-planar 10bit per component (20 bits total): Y[11:2] CbCr[11:2]
+ - YUV422 semi-planar 12bit per component (24 bits total): - Y[11:0] CbCr[11:0]
+ - YUV422 BT656 8bit per component (8 bits total): YCbCr[11:4] (2-cycles)
+ - YUV422 BT656 10bit per component (10 bits total): YCbCr[11:2] (2-cycles)
+ - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
+
+The TDA19973 Video port output pins can be used as follows:
+ - RGB 12bit per color (36 bits total): R[11:0] B[11:0] G[11:0]
+ - YUV444 12bit per color (36 bits total): Y[11:0] Cb[11:0] Cr[11:0]
+ - YUV422 semi-planar 12bit per component (24 bits total): Y[11:0] CbCr[11:0]
+ - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
+
+The Video port output pins are mapped via 4-bit 'pin groups' allowing
+for a variety of connection possibilities including swapping pin order within
+pin groups. The video_portcfg device-tree property consists of register mapping
+pairs which map a chip-specific VP output register to a 4-bit pin group. If
+the pin group needs to be bit-swapped you can use the *_S pin-group defines.
+
+Required Properties:
+ - compatible :
+ - "nxp,tda19971" for the TDA19971
+ - "nxp,tda19973" for the TDA19973
+ - reg : I2C slave address
+ - interrupts : The interrupt number
+ - DOVDD-supply : Digital I/O supply
+ - DVDD-supply : Digital Core supply
+ - AVDD-supply : Analog supply
+ - nxp,vidout-portcfg : array of pairs mapping VP output pins to pin groups.
+
+Optional Properties:
+ - nxp,audout-format : DAI bus format: "i2s" or "spdif".
+ - nxp,audout-width : width of audio output data bus (1-4).
+ - nxp,audout-layout : data layout (0=AP0 used, 1=AP0/AP1/AP2/AP3 used).
+ - nxp,audout-mclk-fs : Multiplication factor between stream rate and codec
+ mclk.
+
+The port node shall contain one endpoint child node for its digital
+output video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Optional Endpoint Properties:

+--------------
+
+This is the device node for the MIPI CSI-2 Receiver core in the i.MX
+SoC. This is a Synopsys Designware MIPI CSI-2 host controller core
+combined with a D-PHY core mixed into the same register block. In
+addition this device consists of an i.MX-specific "CSI2IPU gasket"
+glue logic, also controlled from the same register block. The CSI2IPU
+gasket demultiplexes the four virtual channel streams from the host
+controller's 32-bit output image bus onto four 16-bit parallel busses
+to the i.MX IPU CSIs.
+
+Required properties:
+- compatible : "fsl,imx6-mipi-csi2";
+- reg : physical base address and length of the register set;

+ (the D-PHY clock), video_27m (D-PHY PLL reference
+ clock), and eim_podf;
+- clock-names : must contain "dphy", "ref", "pix";
+- port@* : five port nodes must exist, containing endpoints
+ connecting to the source and sink devices according to
+ of_graph bindings. The first port is an input port,
+ connecting with a MIPI CSI-2 source, and ports 1
+ through 4 are output ports connecting with parallel
+ bus sink endpoint nodes and correspond to the four
+ MIPI CSI-2 virtual channel outputs.
+
+Optional properties:

+
+description: |
+ Mediatek Video Decode is the video decode hardware present in Mediatek
+ SoCs which supports high resolution decoding functionalities. Required
+ parent and child device node.
+
+ About the Decoder Hardware Block Diagram, please check below:
+
+ +------------------------------------------------+-------------------------------------+
+ | | |
+ | input -> lat soc HW -> lat HW -> lat buffer --|--> lat buffer -> core HW -> output |
+ | || || | || |

+ \/ \/ \/

+ | enable/disable |
+ | clk power irq iommu |
+ | (lat/lat soc/core0/core1) |
+ +-------------------------------------------------------------+
+
+ As above, there are parent and child devices, child mean each hardware. The child device
+ controls the information of each hardware independent which include clk/power/irq.
+
+ There are two workqueues in parent device: lat workqueue and core workqueue. They are used
+ to lat and core hardware decoder. Lat workqueue need to get input bitstream and lat buffer,
+ then enable lat to decode, writing the result to lat buffer, dislabe hardware when lat decode
+ done. Core workqueue need to get lat buffer and output buffer, then enable core to decode,
+ writing the result to output buffer, disable hardware when core decode done. These two
+ hardwares will decode each frame cyclically.
+
+ For the smi common may not the same for each hardware, can't combine all hardware in one node,
+ or leading to iommu fault when access dram data.
+
+ Lat soc is a hardware which is related with some larb(local arbiter) ports. For mt8195
+ platform, there are some ports like RDMA, UFO in lat soc larb, need to enable its power and
+ clock when lat start to work, don't have interrupt.

+title: Microchip CSI2 Demux Controller (CSI2DC)
+
+maintainers:
+ - Eugen Hristev <eugen.hristev@microchip.com>
+
+description:
+ CSI2DC - Camera Serial Interface 2 Demux Controller
+
+ CSI2DC is a hardware block that receives incoming data from either from an
+ IDI interface or from a parallel bus interface.
+ It filters IDI packets based on their data type and virtual channel
+ identifier, then converts the byte stream to a pixel stream into a cross
+ clock domain towards a parallel interface that can be read by a sensor
+ controller.
+ IDI interface is Synopsys proprietary.
+ CSI2DC can act a simple bypass bridge if the incoming data is coming from
+ a parallel interface.
+
+ CSI2DC provides two pipes, one video pipe and one data pipe. Video pipe
+ is connected at the output to a sensor controller and the data pipe is
+ accessible as a DMA slave port to a DMA controller.
+
+ CSI2DC supports a single 'port' node as a sink port with either Synopsys
+ 32-bit IDI interface or a parallel interface.
+
+ CSI2DC supports one 'port' node as source port with parallel interface.
+ This is called video pipe.
+ This port has an 'endpoint' that can be connected to a sink port of another
+ controller (next in pipeline).
+
+ CSI2DC also supports direct access to the data through AHB, via DMA channel,
+ called data pipe.
+ For data pipe to be available, a dma controller and a dma channel must be
+ referenced.

+ This is named 'pclk'. The second clock must be the cross domain clock,
+ in which CSI2DC will perform clock crossing. This clock must be fed
+ by the next controller in pipeline, which usually is a sensor controller.
+ Normally this clock should be given by this sensor controller who
+ is also a clock source. This clock is named 'scck', sensor controller clock.

+description: |-
+ The NXP i.MX7 and i.MX8 families contain SoCs that include a MIPI CSI-2
+ receiver IP core named CSIS. The IP core originates from Samsung, and may be
+ compatible with some of the Exynos4 and S5P SoCs. i.MX7 SoCs use CSIS version
+ 3.3, and i.MX8 SoCs use CSIS version 3.6.3.
+
+ While the CSI-2 receiver is separate from the MIPI D-PHY IP core, the PHY is
+ completely wrapped by the CSIS and doesn't expose a control interface of its
+ own. This binding thus covers both IP cores.

+title: Renesas R-Car Gen3 Digital Radio Interface Controller (DRIF)
+
+maintainers:
+ - Ramesh Shanmugasundaram <rashanmu@gmail.com>
+ - Fabrizio Castro <fabrizio.castro.jz@renesas.com>
+
+description: |
+ R-Car Gen3 DRIF is a SPI like receive only slave device. A general
+ representation of DRIF interfacing with a master device is shown below.
+
+ +---------------------+ +---------------------+
+ | |-----SCK------->|CLK |
+ | Master |-----SS-------->|SYNC DRIFn (slave) |
+ | |-----SD0------->|D0 |
+ | |-----SD1------->|D1 |
+ +---------------------+ +---------------------+
+
+ As per datasheet, each DRIF channel (drifn) is made up of two internal
+ channels (drifn0 & drifn1). These two internal channels share the common
+ CLK & SYNC. Each internal channel has its own dedicated resources like
+ irq, dma channels, address space & clock. This internal split is not
+ visible to the external master device.
+
+ The device tree model represents each internal channel as a separate node.
+ The internal channels sharing the CLK & SYNC are tied together by their
+ phandles using a property called "renesas,bonding". For the rest of
+ the documentation, unless explicitly stated, the word channel implies an
+ internal channel.
+
+ When both internal channels are enabled they need to be managed together
+ as one (i.e.) they cannot operate alone as independent devices. Out of the
+ two, one of them needs to act as a primary device that accepts common
+ properties of both the internal channels. This channel is identified by a
+ property called "renesas,primary-bond".
+
+ To summarize,
+ * When both the internal channels that are bonded together are enabled,
+ the zeroth channel is selected as primary-bond. This channels accepts
+ properties common to all the members of the bond.
+ * When only one of the bonded channels need to be enabled, the property
+ "renesas,bonding" or "renesas,primary-bond" will have no effect. That
+ enabled channel can act alone as any other independent device.

+ The FCP is a companion module of video processing modules in the Renesas
+ R-Car Gen3 and RZ/G2 SoCs. It provides data compression and decompression,

+ memory bandwidth.
+
+ There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and
+ FCP for FDP (FCPF). Their configuration and behaviour depend on the module
+ they are paired with. These DT bindings currently support the FCPV and FCPF.

+description:
+ The R-Car Video Input (VIN) device provides video input capabilities for the
+ Renesas R-Car family of devices.
+
+ Each VIN instance has a single parallel input that supports RGB and YUV video,
+ with both external synchronization and BT.656 synchronization for the latter.
+ Depending on the instance the VIN input is connected to external SoC pins, or
+ on Gen3 and RZ/G2 platforms to a CSI-2 receiver.

+description:
+ The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656)
+ video data busses. The I2C bus is the main control bus and additionally the
+ SPI bus is used, mostly for transferring the firmware to and from the
+ device. Two slave device nodes corresponding to these control bus
+ interfaces are required and should be placed under respective bus
+ controller nodes.

+STMicroelectronics STi c8sectpfe binding
+============================================
+
+This document describes the c8sectpfe device bindings that is used to get transport
+stream data into the SoC on the TS pins, and into DDR for further processing.
+
+It is typically used in conjunction with one or more demodulator and tuner devices
+which converts from the RF to digital domain. Demodulators and tuners are usually
+located on an external DVB frontend card connected to SoC TS input pins.
+
+Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
+
+Required properties (controller (parent) node):
+- compatible : Should be "stih407-c8sectpfe"
+
+- reg : Address and length of register sets for each device in
+ "reg-names"
+
+- reg-names : The names of the register addresses corresponding to the
+ registers filled in "reg":
+ - c8sectpfe: c8sectpfe registers
+ - c8sectpfe-ram: c8sectpfe internal sram
+
+- clocks : phandle list of c8sectpfe clocks
+- clock-names : should be "c8sectpfe"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- pinctrl-names : a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
+ must be defined for each tsin child node.
+- pinctrl-0 : phandle referencing pin configuration for this tsin configuration
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+
+Required properties (tsin (child) node):
+
+- tsin-num : tsin id of the InputBlock (must be between 0 to 6)
+- i2c-bus : phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
+- reset-gpios : reset gpio for this tsin channel.
+
+Optional properties (tsin (child) node):
+
+- invert-ts-clk : Bool property to control sense of ts input clock (data stored on falling edge of clk).
+- serial-not-parallel : Bool property to configure input bus width (serial on ts_data<7>).
+- async-not-sync : Bool property to control if data is received in asynchronous mode
+ (all bits/bytes with ts_valid or ts_packet asserted are valid).
+
+- dvb-card : Describes the NIM card connected to this tsin channel.
+
+Example:
+
+/* stih410 SoC b2120 + b2004a + stv0367-pll(NIMB) + stv0367-tda18212 (NIMA) DT example) */

+Texas Instruments VPIF
+----------------------
+
+The TI Video Port InterFace (VPIF) is the primary component for video
+capture and display on the DA850/AM18x family of TI DaVinci/Sitara
+SoCs.
+
+TI Document reference: SPRUH82C, Chapter 35
+http://www.ti.com/lit/pdf/spruh82
+
+Required properties:
+- compatible: must be "ti,da850-vpif"
+- reg: physical base address and length of the registers set for the device;
+- interrupts: should contain IRQ line for the VPIF
+
+Video Capture:
+
+VPIF has a 16-bit parallel bus input, supporting 2 8-bit channels or a
+single 16-bit channel. It should contain one or two port child nodes
+with child 'endpoint' node. If there are two ports then port@0 must
+describe the input and port@1 output channels. Please refer to the
+bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example using 2 8-bit input channels, one of which is connected to an
+I2C-connected TVP5147 decoder:
+
+ vpif: vpif@217000 {
+ compatible = "ti,da850-vpif";
+ reg = <0x217000 0x1000>;
+ interrupts = <92>;
+

+ vpif_input_ch0: endpoint@0 {
+ reg = <0>;
+ bus-width = <8>;
+ remote-endpoint = <&composite_in>;
+ };
+
+ vpif_input_ch1: endpoint@1 {
+ reg = <1>;
+ bus-width = <8>;
+ data-shift = <8>;
+ };
+ };
+
+ port@1 {
+ vpif_output_ch0: endpoint {
+ bus-width = <8>;
+ remote-endpoint = <&composite_out>;
+ };
+ };
+ };
+
+[ ... ]
+
+&i2c0 {
+
+ tvp5147@5d {
+ compatible = "ti,tvp5147";
+ reg = <0x5d>;
+
+ port {
+ composite_in: endpoint {
+ hsync-active = <1>;
+ vsync-active = <1>;
+ pclk-sample = <0>;
+
+ /* VPIF channel 0 (lower 8-bits) */
+ remote-endpoint = <&vpif_input_ch0>;
+ bus-width = <8>;
+ };
+ };
+ };
+
+ adv7343@2a {
+ compatible = "adi,adv7343";
+ reg = <0x2a>;
+
+ port {
+ composite_out: endpoint {
+ adi,dac-enable = <1 1 1>;
+ adi,sd-dac-enable = <1>;
+
+ remote-endpoint = <&vpif_output_ch0>;
+ bus-width = <8>;
+ };
+ };
+ };
+};
+
+
+Alternatively, an example when the bus is configured as a single
+16-bit input (e.g. for raw-capture mode):
+
+ vpif: vpif@217000 {
+ compatible = "ti,da850-vpif";
+ reg = <0x217000 0x1000>;
+ interrupts = <92>;

+ description: |
+ The camera rotation is expressed as the angular difference in degrees
+ between two reference systems, one relative to the camera module, and one
+ defined on the external world scene to be captured when projected on the
+ image sensor pixel array.
+
+ A camera sensor has a 2-dimensional reference system 'Rc' defined by its
+ pixel array read-out order. The origin is set to the first pixel being
+ read out, the X-axis points along the column read-out direction towards
+ the last columns, and the Y-axis along the row read-out direction towards
+ the last row.
+
+ A typical example for a sensor with a 2592x1944 pixel array matrix
+ observed from the front is:
+
+ 2591 X-axis 0
+ <------------------------+ 0
+ .......... ... ..........!
+ .......... ... ..........! Y-axis
+ ... !
+ .......... ... ..........!
+ .......... ... ..........! 1943
+ V
+
+ The external world scene reference system 'Rs' is a 2-dimensional
+ reference system on the focal plane of the camera module. The origin is
+ placed on the top-left corner of the visible scene, the X-axis points
+ towards the right, and the Y-axis points towards the bottom of the scene.
+ The top, bottom, left and right directions are intentionally not defined
+ and depend on the environment in which the camera is used.
+
+ A typical example of a (very common) picture of a shark swimming from left
+ to right, as seen from the camera, is:
+
+ 0 X-axis

+ +-/ \-+¸.·˙ !
+ | (o) | ! Camera focal plane
+ +-----+˙·.¸ !
+ ˙·.¸ !
+ ˙·.¸ !
+ ˙·.¸!
+
+ When projected on the sensor's pixel array, the image and the associated
+ reference system 'Rs' are typically (but not always) inverted, due to the
+ camera module's lens optical inversion effect.
+
+ Assuming the above represented scene of the swimming shark, the lens
+ inversion projects the scene and its reference system onto the sensor
+ pixel array, seen from the front of the camera sensor, as follows:

+ 0 +------------------------------------->
+ 0 X-axis
+
+ Note the shark being upside-down.
+
+ The resulting projected reference system is named 'Rp'.
+
+ The camera rotation property is then defined as the angular difference in
+ the counter-clockwise direction between the camera reference system 'Rc'
+ and the projected scene reference system 'Rp'. It is expressed in degrees
+ as a number in the range [0, 360[.

+description: |
+ Video data pipelines usually consist of external devices, e.g. camera sensors,
+ controlled over an I2C, SPI or UART bus, and SoC internal IP blocks, including
+ video DMA engines and video data processors.
+
+ SoC internal blocks are described by DT nodes, placed similarly to other SoC
+ blocks. External devices are represented as child nodes of their respective
+ bus controller nodes, e.g. I2C.
+
+ Data interfaces on all video devices are described by their child 'port' nodes.
+ Configuration of a port depends on other devices participating in the data
+ transfer and is described by 'endpoint' subnodes.
+
+ device {
+ ...
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ ...
+ endpoint@0 { ... };
+ endpoint@1 { ... };
+ };
+ port@1 { ... };
+ };
+ };
+
+ If a port can be configured to work with more than one remote device on the same
+ bus, an 'endpoint' child node must be provided for each of them. If more than
+ one port is present in a device node or there is more than one endpoint at a
+ port, or port node needs to be associated with a selected hardware interface,
+ a common scheme using '#address-cells', '#size-cells' and 'reg' properties is
+ used.
+
+ All 'port' nodes can be grouped under optional 'ports' node, which allows to
+ specify #address-cells, #size-cells properties independently for the 'port'
+ and 'endpoint' nodes and any child device nodes a device might have.
+
+ Two 'endpoint' nodes are linked with each other through their 'remote-endpoint'
+ phandles. An endpoint subnode of a device contains all properties needed for
+ configuration of this device for data exchange with other device. In most
+ cases properties at the peer 'endpoint' nodes will be identical, however they
+ might need to be different when there is any signal modifications on the bus
+ between two devices, e.g. there are logic signal inverters on the lines.
+
+ It is allowed for multiple endpoints at a port to be active simultaneously,
+ where supported by a device. For example, in case where a data interface of
+ a device is partitioned into multiple data busses, e.g. 16-bit input port
+ divided into two separate ITU-R BT.656 8-bit busses. In such case bus-width
+ and data-shift properties can be used to assign physical data lines to each
+ endpoint node (logical bus).
+
+ Documenting bindings for devices
+ --------------------------------
+
+ All required and optional bindings the device supports shall be explicitly
+ documented in device DT binding documentation. This also includes port and
+ endpoint nodes for the device, including unit-addresses and reg properties
+ where relevant.

+DT bindings for Xilinx video IP cores
+-------------------------------------
+
+Xilinx video IP cores process video streams by acting as video sinks and/or
+sources. They are connected by links through their input and output ports,
+creating a video pipeline.
+
+Each video IP core is represented by an AMBA bus child node in the device
+tree using bindings documented in this directory. Connections between the IP
+cores are represented as defined in ../video-interfaces.txt.
+
+The whole pipeline is represented by an AMBA bus child node in the device
+tree using bindings documented in ./xlnx,video.txt.
+
+Common properties
+-----------------
+
+The following properties are common to all Xilinx video IP cores.
+
+- xlnx,video-format: This property represents a video format transmitted on an
+ AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
+ Video IP and System Design Guide" [UG934]. How the format relates to the IP
+ core is described in the IP core bindings documentation.
+
+- xlnx,video-width: This property qualifies the video format with the sample
+ width expressed as a number of bits per pixel component. All components must
+ use the same width.
+
+- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
+ describes the sensor's color filter array pattern. Supported values are
+ "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
+ defaults to "mono".

+
+description: |
+ The Xilinx MIPI CSI-2 Receiver Subsystem is used to capture MIPI CSI-2
+ traffic from compliant camera sensors and send the output as AXI4 Stream
+ video data for image processing.
+ The subsystem consists of a MIPI D-PHY in slave mode which captures the
+ data packets. This is passed along the MIPI CSI-2 Rx IP which extracts the
+ packet data. The optional Video Format Bridge (VFB) converts this data to
+ AXI4 Stream video data.
+ For more details, please refer to PG232 Xilinx MIPI CSI-2 Receiver Subsystem.
+ Please note that this bindings includes only the MIPI CSI-2 Rx controller
+ and Video Format Bridge and not D-PHY.

+
+Xilinx video IP pipeline processes video streams through one or more Xilinx
+video IP cores. Each video IP core is represented as documented in video.txt
+and IP core specific documentation, xlnx,v-*.txt, in this directory. The DT
+node of the VIPP represents as a top level node of the pipeline and defines
+mappings between DMAs and the video IP cores.
+
+Required properties:
+
+- compatible: Must be "xlnx,video".
+
+- dmas, dma-names: List of one DMA specifier and identifier string (as defined
+ in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port
+ requires a DMA channel with the identifier string set to "port" followed by
+ the port index.
+
+- ports: Video port, using the DT bindings defined in ../video-interfaces.txt.
+
+Required port properties:
+
+- direction: should be either "input" or "output" depending on the direction
+ of stream.

+* Device tree bindings for Atmel EBI
+
+The External Bus Interface (EBI) controller is a bus where you can connect
+asynchronous (NAND, NOR, SRAM, ....) and synchronous memories (SDR/DDR SDRAMs).
+The EBI provides a glue-less interface to asynchronous memories through the SMC
+(Static Memory Controller).
+
+Required properties:
+
+- compatible: "atmel,at91sam9260-ebi"
+ "atmel,at91sam9261-ebi"
+ "atmel,at91sam9263-ebi0"

+ "atmel,at91sam9g45-ebi"
+ "atmel,at91sam9x5-ebi"
+ "atmel,sama5d3-ebi"
+ "microchip,sam9x60-ebi"
+
+- reg: Contains offset/length value for EBI memory mapping.
+ This property might contain several entries if the EBI
+ memory range is not contiguous
+
+- #address-cells: Must be 2.
+ The first cell encodes the CS.
+ The second cell encode the offset into the CS memory
+ range.
+
+- #size-cells: Must be set to 1.
+
+- ranges: Encodes CS to memory region association.
+
+- clocks: Clock feeding the EBI controller.
+ See clock-bindings.txt
+
+Children device nodes are representing device connected to the EBI bus.
+
+Required device node properties:
+
+- reg: Contains the chip-select id, the offset and the length
+ of the memory region requested by the device.
+
+EBI bus configuration will be defined directly in the device subnode.
+
+Optional EBI/SMC properties:
+
+- atmel,smc-bus-width: width of the asynchronous device's data bus
+ 8, 16 or 32.
+ Default to 8 when undefined.
+
+- atmel,smc-byte-access-type "write" or "select" (see Atmel datasheet).
+ Default to "select" when undefined.
+
+- atmel,smc-read-mode "nrd" or "ncs".
+ Default to "ncs" when undefined.
+
+- atmel,smc-write-mode "nwe" or "ncs".
+ Default to "ncs" when undefined.
+
+- atmel,smc-exnw-mode "disabled", "frozen" or "ready".
+ Default to "disabled" when undefined.
+
+- atmel,smc-page-mode enable page mode if present. The provided value
+ defines the page size (supported values: 4, 8,
+ 16 and 32).
+
+- atmel,smc-tdf-mode: "normal" or "optimized". When set to
+ "optimized" the data float time is optimized
+ depending on the next device being accessed
+ (next device setup time is subtracted to the
+ current device data float time).
+ Default to "normal" when undefined.
+
+If at least one atmel,smc- property is defined the following SMC timing
+properties become mandatory. In the other hand, if none of the atmel,smc-
+properties are specified, we assume that the EBI bus configuration will be
+handled by the sub-device driver, and none of those properties should be
+defined.
+
+All the timings are expressed in nanoseconds (see Atmel datasheet for a full
+description).

+description:
+ The DDRC block is integrated in i.MX8M for interfacing with DDR based
+ memories.
+
+ It supports switching between different frequencies at runtime but during
+ this process RAM itself becomes briefly inaccessible so actual frequency
+ switching is implemented by TF-A code which runs from a SRAM area.
+
+ The Linux driver for the DDRC doesn't even map registers (they're included
+ for the sake of "describing hardware"), it mostly just exposes firmware
+ capabilities through standard Linux mechanism like devfreq and OPP tables.

+ The hardware block diagram please check bindings/iommu/mediatek,iommu.yaml
+
+ MediaTek SMI have two generations of HW architecture, here is the list
+ which generation the SoCs use:
+ generation 1: mt2701 and mt7623.
+ generation 2: mt2712, mt6779, mt8167, mt8173, mt8183, mt8186, mt8188, mt8192 and mt8195.
+
+ There's slight differences between the two SMI, for generation 2, the
+ register which control the iommu port is at each larb's register base. But
+ for generation 1, the register is at smi ao base(smi always on register
+ base). Besides that, the smi async clock should be prepared and enabled for
+ SMI generation 1 to transform the smi clock into emi clock domain, but that is
+ not needed for SMI generation 2.

+Device tree bindings for MVEBU Device Bus controllers
+
+The Device Bus controller available in some Marvell's SoC allows to control
+different types of standard memory and I/O devices such as NOR, NAND, and FPGA.
+The actual devices are instantiated from the child nodes of a Device Bus node.
+
+Required properties:
+
+ - compatible: Armada 370/XP SoC are supported using the
+ "marvell,mvebu-devbus" compatible string.
+
+ Orion5x SoC are supported using the
+ "marvell,orion-devbus" compatible string.
+
+ - reg: A resource specifier for the register space.
+ This is the base address of a chip select within
+ the controller's register space.
+ (see the example below)
+
+ - #address-cells: Must be set to 1
+ - #size-cells: Must be set to 1
+ - ranges: Must be set up to reflect the memory layout with four
+ integer values for each chip-select line in use:
+ 0 <physical address of mapping> <size>
+
+Optional properties:
+
+ - devbus,keep-config This property can optionally be used to keep
+ using the timing parameters set by the
+ bootloader. It makes all the timing properties
+ described below unused.
+
+Timing properties for child nodes:
+
+Read parameters:
+
+ - devbus,turn-off-ps: Defines the time during which the controller does not
+ drive the AD bus after the completion of a device read.
+ This prevents contentions on the Device Bus after a read
+ cycle from a slow device.
+ Mandatory, except if devbus,keep-config is used.
+
+ - devbus,bus-width: Defines the bus width, in bits (e.g. <16>).
+ Mandatory, except if devbus,keep-config is used.
+
+ - devbus,badr-skew-ps: Defines the time delay from from A[2:0] toggle,
+ to read data sample. This parameter is useful for
+ synchronous pipelined devices, where the address
+ precedes the read data by one or two cycles.
+ Mandatory, except if devbus,keep-config is used.
+
+ - devbus,acc-first-ps: Defines the time delay from the negation of
+ ALE[0] to the cycle that the first read data is sampled
+ by the controller.
+ Mandatory, except if devbus,keep-config is used.
+
+ - devbus,acc-next-ps: Defines the time delay between the cycle that
+ samples data N and the cycle that samples data N+1
+ (in burst accesses).
+ Mandatory, except if devbus,keep-config is used.
+
+ - devbus,rd-setup-ps: Defines the time delay between DEV_CSn assertion to
+ DEV_OEn assertion. If set to 0 (default),
+ DEV_OEn and DEV_CSn are asserted at the same cycle.
+ This parameter has no affect on <acc-first-ps> parameter
+ (no affect on first data sample). Set <rd-setup-ps>
+ to a value smaller than <acc-first-ps>.
+ Mandatory for "marvell,mvebu-devbus" compatible string,
+ except if devbus,keep-config is used.
+
+ - devbus,rd-hold-ps: Defines the time between the last data sample to the
+ de-assertion of DEV_CSn. If set to 0 (default),
+ DEV_OEn and DEV_CSn are de-asserted at the same cycle
+ (the cycle of the last data sample).
+ This parameter has no affect on DEV_OEn de-assertion.
+ DEV_OEn is always de-asserted the next cycle after
+ last data sampled. Also this parameter has no
+ affect on <turn-off-ps> parameter.
+ Set <rd-hold-ps> to a value smaller than <turn-off-ps>.
+ Mandatory for "marvell,mvebu-devbus" compatible string,
+ except if devbus,keep-config is used.
+
+Write parameters:
+
+ - devbus,ale-wr-ps: Defines the time delay from the ALE[0] negation cycle
+ to the DEV_WEn assertion.
+ Mandatory.
+
+ - devbus,wr-low-ps: Defines the time during which DEV_WEn is active.
+ A[2:0] and Data are kept valid as long as DEV_WEn
+ is active. This parameter defines the setup time of
+ address and data to DEV_WEn rise.
+ Mandatory.
+
+ - devbus,wr-high-ps: Defines the time during which DEV_WEn is kept
+ inactive (high) between data beats of a burst write.
+ DEV_A[2:0] and Data are kept valid (do not toggle) for
+ <wr-high-ps> - <tick> ps.
+ This parameter defines the hold time of address and
+ data after DEV_WEn rise.
+ Mandatory.
+
+ - devbus,sync-enable: Synchronous device enable.
+ 1: True
+ 0: False
+ Mandatory for "marvell,mvebu-devbus" compatible string,
+ except if devbus,keep-config is used.
+
+An example for an Armada XP GP board, with a 16 MiB NOR device as child
+is showed below. Note that the Device Bus driver is in charge of allocating
+the mbus address decoding window for each of its child devices.
+The window is created using the chip select specified in the child
+device node together with the base address and size specified in the ranges
+property. For instance, in the example below the allocated decoding window
+will start at base address 0xf0000000, with a size 0x1000000 (16 MiB)
+for chip select 0 (a.k.a DEV_BOOTCS).
+
+This address window handling is done in this mvebu-devbus only as a temporary
+solution. It will be removed when the support for mbus device tree binding is
+added.
+
+The reg property implicitly specifies the chip select as this:
+
+ 0x10400: DEV_BOOTCS
+ 0x10408: DEV_CS0
+ 0x10410: DEV_CS1
+ 0x10418: DEV_CS2
+ 0x10420: DEV_CS3

+description: |
+ The Nuvoton BMC SoC supports DDR4 memory with or without ECC (error correction
+ check).
+
+ The memory controller supports single bit error correction, double bit error
+ detection (in-line ECC in which a section (1/8th) of the memory device used to
+ store data is used for ECC storage).
+
+ Note, the bootloader must configure ECC mode for the memory controller.

+description: |
+ The NVIDIA Tegra186 SoC features a 128 bit memory controller that is split
+ into four 32 bit channels to support LPDDR4 with x16 subpartitions. The MC
+ handles memory requests for 40-bit virtual addresses from internal clients
+ and arbitrates among them to allocate memory bandwidth.
+
+ Up to 15 GiB of physical memory can be supported. Security features such as
+ encryption of traffic to and from DRAM via general security apertures are
+ available for video and other secure applications, as well as DRAM ECC for
+ automotive safety applications (single bit error correction and double bit
+ error detection).

+ The Tegra20 Memory Controller merges request streams from various client
+ interfaces into request stream(s) for the various memory target devices,
+ and returns response data to the various clients. The Memory Controller
+ has a configurable arbitration algorithm to allow the user to fine-tune
+ performance among the various clients.
+
+ Tegra20 Memory Controller includes the GART (Graphics Address Relocation
+ Table) which allows Memory Controller to provide a linear view of a
+ fragmented memory pages.

+description: |
+ Tegra30 Memory Controller architecturally consists of the following parts:
+
+ Arbitration Domains, which can handle a single request or response per
+ clock from a group of clients. Typically, a system has a single Arbitration
+ Domain, but an implementation may divide the client space into multiple
+ Arbitration Domains to increase the effective system bandwidth.
+
+ Protocol Arbiter, which manage a related pool of memory devices. A system
+ may have a single Protocol Arbiter or multiple Protocol Arbiters.
+
+ Memory Crossbar, which routes request and responses between Arbitration
+ Domains and Protocol Arbiters. In the simplest version of the system, the
+ Memory Crossbar is just a pass through between a single Arbitration Domain
+ and a single Protocol Arbiter.
+
+ Global Resources, which include things like configuration registers which
+ are shared across the Memory Subsystem.
+
+ The Tegra30 Memory Controller handles memory requests from internal clients
+ and arbitrates among them to allocate memory bandwidth for DDR3L and LPDDR2
+ SDRAMs.

+description: |
+ The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the
+ DRAM memory chips are connected. The driver is to monitor the controller in
+ runtime and switch frequency and voltage. To monitor the usage of the
+ controller in runtime, the driver uses the PPMU (Platform Performance
+ Monitoring Unit), which is able to measure the current load of the memory.
+ When 'userspace' governor is used for the driver, an application is able to
+ switch the DMC and memory frequency.

+ - to meet the access time requirements of the external devices
+ All external devices share the addresses, data and control signals with the
+ controller. Each external device is accessed by means of a unique Chip

+ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
+can be accessed at any given time via four chip selects with 64M byte access
+per chip select. Synchronous memories such as DDR1 SD RAM, SDR SDRAM
+and Mobile SDR are not supported.

+Kestone - http://www.ti.com/lit/ug/sprugz3a/sprugz3a.pdf
+
+Required properties:
+
+- compatible: "ti,davinci-aemif"
+ "ti,keystone-aemif"
+ "ti,da850-aemif"
+
+- reg: contains offset/length value for AEMIF control registers
+ space.
+
+- #address-cells: Must be 2. The partition number has to be encoded in the
+ first address cell and it may accept values 0..N-1
+ (N - total number of partitions). It's recommended to
+ assign N-1 number for the control partition. The second
+ cell is the offset into the partition.
+
+- #size-cells: Must be set to 1.
+
+- ranges: Contains memory regions. There are two types of
+ ranges/partitions:
+ - CS-specific partition/range. If continuous, must be
+ set up to reflect the memory layout for 4 chipselects,
+ if not then additional range/partition can be added and
+ child device can select the proper one.
+ - control partition which is common for all CS
+ interfaces.
+
+- clocks: the clock feeding the controller clock. Required only
+ if clock tree data present in device tree.
+ See clock-bindings.txt
+
+- clock-names: clock name. It has to be "aemif". Required only if clock
+ tree data present in device tree, in another case don't
+ use it.
+ See clock-bindings.txt
+
+- clock-ranges: Empty property indicating that child nodes can inherit
+ named clocks. Required only if clock tree data present
+ in device tree.
+ See clock-bindings.txt
+
+
+Child chip-select (cs) nodes contain the memory devices nodes connected to
+such as NOR (e.g. cfi-flash) and NAND (ti,davinci-nand, see davinci-nand.txt).
+There might be board specific devices like FPGAs.
+
+Required child cs node properties:
+
+- #address-cells: Must be 2.
+
+- #size-cells: Must be 1.
+
+- ranges: Empty property indicating that child nodes can inherit
+ memory layout.

+- clock-ranges: Empty property indicating that child nodes can inherit
+ named clocks. Required only if clock tree data present
+ in device tree.
+
+- ti,cs-chipselect: number of chipselect. Indicates on the aemif driver
+ which chipselect is used for accessing the memory. For
+ compatibles "ti,davinci-aemif" and "ti,keystone-aemif"
+ it can be in range [0-3]. For compatible
+ "ti,da850-aemif" range is [2-5].
+
+Optional child cs node properties:
+
+- ti,cs-bus-width: width of the asynchronous device's data bus
+ 8 or 16 if not preset 8
+
+- ti,cs-select-strobe-mode: enable/disable select strobe mode
+ In select strobe mode chip select behaves as
+ the strobe and is active only during the strobe
+ period. If present then enable.
+
+- ti,cs-extended-wait-mode: enable/disable extended wait mode
+ if set, the controller monitors the EMIFWAIT pin
+ mapped to that chip select to determine if the
+ device wants to extend the strobe period. If
+ present then enable.
+
+- ti,cs-min-turnaround-ns: minimum turn around time, ns
+ Time between the end of one asynchronous memory
+ access and the start of another asynchronous
+ memory access. This delay is not incurred
+ between a read followed by read or a write
+ followed by a write to same chip select.
+
+- ti,cs-read-setup-ns: read setup width, ns
+ Time between the beginning of a memory cycle
+ and the activation of read strobe.
+ Minimum value is 1 (0 treated as 1).
+
+- ti,cs-read-strobe-ns: read strobe width, ns
+ Time between the activation and deactivation of
+ the read strobe.
+ Minimum value is 1 (0 treated as 1).
+
+- ti,cs-read-hold-ns: read hold width, ns
+ Time between the deactivation of the read
+ strobe and the end of the cycle (which may be
+ either an address change or the deactivation of
+ the chip select signal.
+ Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-setup-ns: write setup width, ns
+ Time between the beginning of a memory cycle
+ and the activation of write strobe.
+ Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-strobe-ns: write strobe width, ns
+ Time between the activation and deactivation of
+ the write strobe.
+ Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-hold-ns: write hold width, ns
+ Time between the deactivation of the write
+ strobe and the end of the cycle (which may be
+ either an address change or the deactivation of
+ the chip select signal.
+ Minimum value is 1 (0 treated as 1).
+
+If any of the above parameters are absent, current parameter value will be taken

+* EMIF family of TI SDRAM controllers
+
+EMIF - External Memory Interface - is an SDRAM controller used in
+TI SoCs. EMIF supports, based on the IP revision, one or more of
+DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance
+of the EMIF IP and memory parts attached to it. Certain revisions
+of the EMIF controller also contain optional ECC support, which
+corrects one bit errors and detects two bit errors.
+
+Required properties:
+- compatible : Should be of the form "ti,emif-<ip-rev>" where <ip-rev>
+ is the IP revision of the specific EMIF instance. For newer controllers,
+ compatible should be one of the following:
+ "ti,emif-am3352"
+ "ti,emif-am4372"
+ "ti,emif-dra7xx"
+ "ti,emif-keystone"
+
+- phy-type : <u32> indicating the DDR phy type. Following are the
+ allowed values
+ <1> : Attila PHY
+ <2> : Intelli PHY
+
+- device-handle : phandle to a "lpddr2" node representing the memory part
+
+- ti,hwmods : For TI hwmods processing and omap device creation
+ the value shall be "emif<n>" where <n> is the number of the EMIF
+ instance with base 1.
+- interrupts : interrupt used by the controller
+
+Required only for "ti,emif-am3352" and "ti,emif-am4372":
+- sram : Phandles for generic sram driver nodes,
+ first should be type 'protect-exec' for the driver to use to copy
+ and run PM functions, second should be regular pool to be used for
+ data region for code. See Documentation/devicetree/bindings/sram/sram.yaml
+ for more details.
+
+Optional properties:
+- cs1-used : Have this property if CS1 of this EMIF
+ instance has a memory part attached to it. If there is a memory
+ part attached to CS1, it should be the same type as the one on CS0,
+ so there is no need to give the details of this memory part.
+
+- cal-resistor-per-cs : Have this property if the board has one
+ calibration resistor per chip-select.
+
+- hw-caps-read-idle-ctrl: Have this property if the controller
+ supports read idle window programming
+
+- hw-caps-dll-calib-ctrl: Have this property if the controller
+ supports dll calibration control
+
+- hw-caps-ll-interface : Have this property if the controller
+ has a low latency interface and corresponding interrupt events

+ The OCM supports 64-bit wide ECC functionality to detect multi-bit errors
+ and recover from a single-bit memory fault.On a write, if all bytes are
+ being written, the ECC is generated and written into the ECC RAM along with
+ the write-data that is written into the data RAM. If one or more bytes are
+ not written, then the read operation results in an correctable error or
+ uncorrectable error.

+
+description:
+ The LPC bus is a means to bridge a host CPU to a number of low-bandwidth
+ peripheral devices, replacing the use of the ISA bus in the age of PCI[0]. The
+ primary use case of the Aspeed LPC controller is as a slave on the bus
+ (typically in a Baseboard Management Controller SoC), but under certain
+ conditions it can also take the role of bus master.
+
+ The LPC controller is represented as a multi-function device to account for the
+ mix of functionality, which includes, but is not limited to
+
+ * An IPMI Block Transfer[2] Controller
+
+ * An LPC Host Interface Controller manages functions exposed to the host such
+ as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
+ management and bus snoop configuration.
+
+ * A set of SuperIO[3] scratch registers enabling implementation of e.g. custom
+ hardware management protocols for handover between the host and baseboard
+ management controller.
+
+ Additionally the state of the LPC controller influences the pinmux
+ configuration, therefore the host portion of the controller is exposed as a
+ syscon as a means to arbitrate access.

+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: is <2> and their usage is compliant to the 2 cells

+
+- system-power-controller: Indicates that this PMIC is controlling the
+ system power, see [1] for more details.
+
+[1] Documentation/devicetree/bindings/power/power-controller.txt
+
+Optional subnodes and their properties:
+=======================================
+
+Flexible power sequence configurations:
+--------------------------------------
+The Flexible Power Sequencer (FPS) allows each regulator to power up under
+hardware or software control. Additionally, each regulator can power on
+independently or among a group of other regulators with an adjustable power-up
+and power-down delays (sequencing). GPIO1, GPIO2, and GPIO3 can be programmed
+to be part of a sequence allowing external regulators to be sequenced along
+with internal regulators. 32KHz clock can be programmed to be part of a
+sequence.
+
+The flexible sequencing structure consists of two hardware enable inputs
+(EN0, EN1), and 3 master sequencing timers called FPS0, FPS1 and FPS2.
+Each master sequencing timer is programmable through its configuration
+register to have a hardware enable source (EN1 or EN2) or a software enable
+source (SW). When enabled/disabled, the master sequencing timer generates
+eight sequencing events on different time periods called slots. The time
+period between each event is programmable within the configuration register.
+Each regulator, GPIO1, GPIO2, GPIO3, and 32KHz clock has a flexible power
+sequence slave register which allows its enable source to be specified as
+a flexible power sequencer timer or a software bit. When a FPS source of
+regulators, GPIOs and clocks specifies the enable source to be a flexible
+power sequencer, the power up and power down delays can be specified in
+the regulators, GPIOs and clocks flexible power sequencer configuration
+registers.
+
+When FPS event cleared (set to LOW), regulators, GPIOs and 32KHz
+clock are set into following state at the sequencing event that
+corresponds to its flexible sequencer configuration register.
+ Sleep state: In this state, regulators, GPIOs
+ and 32KHz clock get disabled at
+ the sequencing event.
+ Global Low Power Mode (GLPM): In this state, regulators are set in
+ low power mode at the sequencing event.
+
+The configuration parameters of FPS is provided through sub-node "fps"
+and their child for FPS specific. The child node name for FPS are "fps0",
+"fps1", and "fps2" for FPS0, FPS1 and FPS2 respectively.
+
+The FPS configurations like FPS source, power up and power down slots for
+regulators, GPIOs and 32kHz clocks are provided in their respective
+configuration nodes which is explained in respective sub-system DT
+binding document.
+
+There is need for different FPS configuration parameters based on system
+state like when system state changed from active to suspend or active to
+power off (shutdown).
+
+Optional properties:
+-------------------
+-maxim,fps-event-source: u32, FPS event source like external
+ hardware input to PMIC i.e. EN0, EN1 or
+ software (SW).
+ The macros are defined on
+ dt-bindings/mfd/max77620.h
+ for different control source.
+ - MAX77620_FPS_EVENT_SRC_EN0
+ for hardware input pin EN0.
+ - MAX77620_FPS_EVENT_SRC_EN1
+ for hardware input pin EN1.
+ - MAX77620_FPS_EVENT_SRC_SW
+ for software control.
+
+-maxim,shutdown-fps-time-period-us: u32, FPS time period in microseconds
+ when system enters in to shutdown
+ state.
+
+-maxim,suspend-fps-time-period-us: u32, FPS time period in microseconds
+ when system enters in to suspend state.
+
+-maxim,device-state-on-disabled-event: u32, describe the PMIC state when FPS
+ event cleared (set to LOW) whether it
+ should go to sleep state or low-power
+ state. Following are valid values:
+ - MAX77620_FPS_INACTIVE_STATE_SLEEP
+ to set the PMIC state to sleep.
+ - MAX77620_FPS_INACTIVE_STATE_LOW_POWER
+ to set the PMIC state to low
+ power.
+ Absence of this property or other value
+ will not change device state when FPS
+ event get cleared.
+
+Here supported time periods by device in microseconds are as follows:
+MAX77620 supports 40, 80, 160, 320, 640, 1280, 2560 and 5120 microseconds.
+MAX20024 supports 20, 40, 80, 160, 320, 640, 1280 and 2540 microseconds.
+MAX77663 supports 20, 40, 80, 160, 320, 640, 1280 and 2540 microseconds.
+
+-maxim,power-ok-control: configure map power ok bit
+ 1: Enables POK(Power OK) to control nRST_IO and GPIO1
+ POK function.
+ 0: Disables POK control.
+ if property missing, do not configure MPOK bit.
+ If POK mapping is enabled for GPIO1/nRST_IO then,
+ GPIO1/nRST_IO pins are HIGH only if all rails
+ that have POK control enabled are HIGH.
+ If any of the rails goes down(which are enabled for POK
+ control) then, GPIO1/nRST_IO goes LOW.
+ this property is valid for max20024 only.
+
+For DT binding details of different sub modules like GPIO, pincontrol,
+regulator, power, please refer respective device-tree binding document
+under their respective sub-system directories.
+
+Example:
+--------
+#include <dt-bindings/mfd/max77620.h>
+
+max77620@3c {
+ compatible = "maxim,max77620";
+ reg = <0x3c>;

+* Maxim MAX8998, National/TI LP3974 multi-function device
+
+The Maxim MAX8998 is a multi-function device which includes voltage/current
+regulators, real time clock, battery charging controller and several
+other sub-blocks. It is interfaced using an I2C interface. Each sub-block
+is addressed by the host system using different i2c slave address.
+
+PMIC sub-block
+--------------
+
+The PMIC sub-block contains a number of voltage and current regulators,
+with controllable parameters and dynamic voltage scaling capability.
+In addition, it includes a real time clock and battery charging controller
+as well. It is accessible at I2C address 0x66.
+
+Required properties:
+- compatible: Should be one of the following:
+ - "maxim,max8998" for Maxim MAX8998
+ - "national,lp3974" or "ti,lp3974" for National/TI LP3974.
+- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
+
+Optional properties:
+- interrupts: Interrupt specifiers for two interrupt sources.
+ - First interrupt specifier is for main interrupt.
+ - Second interrupt specifier is for power-on/-off interrupt.
+- max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
+ for buck 1 dvs. The format of the gpio specifier depends on the gpio
+ controller.
+- max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
+ for buck 2 dvs. The format of the gpio specifier depends on the gpio
+ controller.
+- max8998,pmic-buck1-default-dvs-idx: Default voltage setting selected from
+ the possible 4 options selectable by the dvs gpios. The value of this
+ property should be 0, 1, 2 or 3. If not specified or out of range,
+ a default value of 0 is taken.
+- max8998,pmic-buck2-default-dvs-idx: Default voltage setting selected from
+ the possible 2 options selectable by the dvs gpios. The value of this
+ property should be 0 or 1. If not specified or out of range, a default
+ value of 0 is taken.
+- max8998,pmic-buck-voltage-lock: If present, disallows changing of
+ preprogrammed buck dvfs voltages.
+
+Additional properties required if max8998,pmic-buck1-dvs-gpios is defined:
+- max8998,pmic-buck1-dvs-voltage: An array of 4 voltage values in microvolts
+ for buck1 regulator that can be selected using dvs gpio.
+
+Additional properties required if max8998,pmic-buck2-dvs-gpio is defined:
+- max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts
+ for buck2 regulator that can be selected using dvs gpio.
+
+Regulators: All the regulators of MAX8998 to be instantiated shall be
+listed in a child node named 'regulators'. Each regulator is represented
+by a child node of the 'regulators' node.
+
+ regulator-name {
+ /* standard regulator bindings here */
+ };
+
+Following regulators of the MAX8998 PMIC block are supported. Note that
+the 'n' in regulator name, as in LDOn or BUCKn, represents the LDO or BUCK
+number as described in MAX8998 datasheet.
+
+ - LDOn
+ - valid values for n are 2 to 17
+ - Example: LDO2, LDO10, LDO17
+ - BUCKn
+ - valid values for n are 1 to 4.
+ - Example: BUCK1, BUCK2, BUCK3, BUCK4
+
+ - ENVICHG: Battery Charging Current Monitor Output. This is a fixed
+ voltage type regulator
+
+ - ESAFEOUT1: (ldo19)
+ - ESAFEOUT2: (ld020)
+
+ - CHARGER: main battery charger current control
+
+Standard regulator bindings are used inside regulator subnodes. Check
+ Documentation/devicetree/bindings/regulator/regulator.txt
+for more details.

+description: |
+ This is a part of device tree bindings for Maxim MAX77802 Power Management
+ Integrated Circuit (PMIC).
+
+ The Maxim MAX77802 is a Power Management IC which includes voltage and
+ current regulators (10 high efficiency Buck regulators and 32 Low-DropOut
+ (LDO)), RTC and clock outputs.
+
+ The MAX77802 provides two 32.768khz clock outputs that can be controlled
+ (gated/ungated) over I2C. The clock IDs are defined as preprocessor macros
+ in dt-bindings/clock/maxim,max77802.h.

+Multi-Function Devices (MFD)
+
+These devices comprise a nexus for heterogeneous hardware blocks containing
+more than one non-unique yet varying hardware functionality.
+
+A typical MFD can be:
+
+- A mixed signal ASIC on an external bus, sometimes a PMIC (Power Management
+ Integrated Circuit) that is manufactured in a lower technology node (rough
+ silicon) that handles analog drivers for things like audio amplifiers, LED
+ drivers, level shifters, PHY (physical interfaces to things like USB or
+ ethernet), regulators etc.
+
+- A range of memory registers containing "miscellaneous system registers" also
+ known as a system controller "syscon" or any other memory range containing a
+ mix of unrelated hardware devices.
+
+Optional properties:
+
+- compatible : "simple-mfd" - this signifies that the operating system should
+ consider all subnodes of the MFD device as separate devices akin to how
+ "simple-bus" indicates when to see subnodes as children for a simple
+ memory-mapped bus. For more complex devices, when the nexus driver has to
+ probe registers to figure out what child devices exist etc, this should not
+ be used. In the latter case the child devices will be determined by the
+ operating system.
+
+- ranges: Describes the address mapping relationship to the parent. Should set
+ the child's base address to 0, the physical address within parent's address
+ space, and the length of the address map.
+
+- #address-cells: Specifies the number of cells used to represent physical base
+ addresses. Must be present if ranges is used.
+
+- #size-cells: Specifies the number of cells used to represent the size of an
+ address. Must be present if ranges is used.
+
+Example:
+
+foo@1000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x01000 0x1000>;
+
+ led@8.0 {
+ compatible = "register-bit-led";
+ offset = <0x08>;
+ mask = <0x01>;
+ label = "myled";
+ default-state = "on";

+Motorola CPCAP PMIC device tree binding
+
+Required properties:
+- compatible : One or both of "motorola,cpcap" or "ste,6556002"
+- reg : SPI chip select
+- interrupts : The interrupt line the device is connected to
+- interrupt-controller : Marks the device node as an interrupt controller
+- #interrupt-cells : The number of cells to describe an IRQ, should be 2
+- #address-cells : Child device offset number of cells, should be 1
+- #size-cells : Child device size number of cells, should be 0
+- spi-max-frequency : Typically set to 3000000
+- spi-cs-high : SPI chip select direction
+
+Optional subnodes:
+
+The sub-functions of CPCAP get their own node with their own compatible values,
+which are described in the following files:
+
+- Documentation/devicetree/bindings/power/supply/cpcap-battery.yaml
+- Documentation/devicetree/bindings/power/supply/cpcap-charger.yaml

+- Documentation/devicetree/bindings/leds/leds-cpcap.txt
+- Documentation/devicetree/bindings/iio/adc/motorola,cpcap-adc.yaml
+
+The only exception is the audio codec. Instead of a compatible value its
+node must be named "audio-codec".
+
+Required properties for the audio-codec subnode:
+
+- #sound-dai-cells = <1>;
+
+The audio-codec provides two DAIs. The first one is connected to the
+Stereo HiFi DAC and the second one is connected to the Voice DAC.

+description: |
+ The Ocelot ethernet switch family contains chips that have an internal CPU
+ (VSC7513, VSC7514) and chips that don't (VSC7511, VSC7512). All switches have
+ the option to be controlled externally via external interfaces like SPI or
+ PCIe.
+
+ The switch family is a multi-port networking switch that supports many
+ interfaces. Additionally, the device can perform pin control, MDIO buses, and
+ external GPIO expanders.

+title: Qualcomm SPMI PMICs multi-function device
+
+description: |
+ Some Qualcomm PMICs used with the Snapdragon series SoCs are interfaced
+ to the chip via the SPMI (System Power Management Interface) bus.
+ Support for multiple independent functions are implemented by splitting the
+ 16-bit SPMI peripheral address space into 256 smaller fixed-size regions, 256 bytes
+ each. A function can consume one or more of these fixed-size register regions.
+
+ The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other
+ PMICs. These PMICs use a "QPNP" scheme through SPMI interface.
+ QPNP is effectively a partitioning scheme for dividing the SPMI extended
+ register space up into logical pieces, and set of fixed register
+ locations/definitions within these regions, with some of these regions
+ specifically used for interrupt handling.

+# i.MX8 documentation for further information regarding SNVS state. When a
+# reset is done via SNVS state the PMIC OTP data is not reload. This causes
+# power outputs that have been under SW control to stay down when reset has
+# switched power state to SNVS. If reset is done via READY state the power
+# outputs will be returned to HW control by OTP loading. Thus the reset
+# target state is set to READY by default. If SNVS state is used the boot

+description: |
+ BD71847AMWV and BD71850MWV are programmable Power Management ICs for powering
+ single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is
+ optimized for low BOM cost and compact solution footprint. BD71847MWV and
+ BD71850MWV integrate 6 Buck regulators and 6 LDOs.
+ Datasheets are available at

+# The BD71847 abd BD71850 support two different HW states as reset target

+# and external devices apart from the SNVS power domain are shut off. Please
+# refer to NXP i.MX8 documentation for further information regarding SNVS
+# state. When a reset is done via SNVS state the PMIC OTP data is not reload.
+# This causes power outputs that have been under SW control to stay down when
+# reset has switched power state to SNVS. If reset is done via READY state the

+The Spreadtrum SC27xx series PMICs contain SC2720, SC2721, SC2723, SC2730
+and SC2731. The Spreadtrum PMIC belonging to SC27xx series integrates all
+mobile handset power management, audio codec, battery management and user
+interface support function in a single chip. It has 6 major functional
+blocks:
+- DCDCs to support CPU, memory.
+- LDOs to support both internal and external requirement.
+- Battery management system, such as charger, fuel gauge.
+- Audio codec.
+- User interface function, such as indicator, flash LED and so on.
+- IC level interface, such as power on/off control, RTC and typec and so on.
+
+Required properties:
+- compatible: Should be one of the following:
+ "sprd,sc2720"
+ "sprd,sc2721"
+ "sprd,sc2723"
+ "sprd,sc2730"
+ "sprd,sc2731"
+- reg: The address of the device chip select, should be 0.
+- spi-max-frequency: Typically set to 26000000.
+- interrupts: The interrupt line the device is connected to.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: The number of cells to describe an PMIC IRQ, must be 2.
+- #address-cells: Child device offset number of cells, must be 1.
+- #size-cells: Child device size number of cells, must be 0.
+
+Example:
+pmic@0 {
+ compatible = "sprd,sc2731";
+ reg = <0>;
+ spi-max-frequency = <26000000>;
+ interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};

+title: ST-Ericsson Analog Baseband AB8500 and AB8505
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description:
+ the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
+ handling power management (regulators), analog-to-digital conversion
+ (ADC), battery charging, fuel gauging of the battery, battery-backed
+ RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
+ in connection with the DB8500 digital baseband. The DB8500 PRCMU
+ communicates directly and autonomously with the AB8500 and thus it
+ appears as a subnode of the DB8500 PRCMU. An altered version called
+ AB8505 also exist, the difference in AB8505 is that some of the USB and
+ USB charging handling has changed, and it has an embedded USB-to-serial
+ converter. Most subblocks takes their interrupts directly from the
+ AB8500 embedded interrupt controller.

+* Toshiba TC3589x multi-purpose expander
+
+The Toshiba TC3589x series are I2C-based MFD devices which may expose the
+following built-in devices: gpio, keypad, rotator (vibrator), PWM (for
+e.g. LEDs or vibrators) The included models are:
+
+- TC35890
+- TC35892
+- TC35893
+- TC35894
+- TC35895
+- TC35896
+
+Required properties:
+ - compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
+ "toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
+ - reg : I2C address of the device
+ - interrupts : the interrupt on the parent the controller is connected to
+ - interrupt-controller : marks the device node as an interrupt controller
+ - #interrupt-cells : should be <1>, the first cell is the IRQ offset on this
+ TC3589x interrupt controller.
+
+Optional nodes:
+
+- GPIO
+ This GPIO module inside the TC3589x has 24 (TC35890, TC35892) or 20
+ (other models) GPIO lines.
+ - compatible : must be "toshiba,tc3589x-gpio"
+ - interrupts : interrupt on the parent, which must be the tc3589x MFD device
+ - interrupt-controller : marks the device node as an interrupt controller
+ - #interrupt-cells : should be <2>, the first cell is the IRQ offset on this
+ TC3589x GPIO interrupt controller, the second cell is the interrupt flags
+ in accordance with <dt-bindings/interrupt-controller/irq.h>. The following
+ flags are valid:
+ - IRQ_TYPE_LEVEL_LOW
+ - IRQ_TYPE_LEVEL_HIGH
+ - IRQ_TYPE_EDGE_RISING
+ - IRQ_TYPE_EDGE_FALLING
+ - IRQ_TYPE_EDGE_BOTH
+ - gpio-controller : marks the device node as a GPIO controller
+ - #gpio-cells : should be <2>, the first cell is the GPIO offset on this
+ GPIO controller, the second cell is the flags.
+
+- Keypad
+ This keypad is the same on all variants, supporting up to 96 different
+ keys. The linux-specific properties are modeled on those already existing
+ in other input drivers.
+ - compatible : must be "toshiba,tc3589x-keypad"
+ - debounce-delay-ms : debounce interval in milliseconds
+ - keypad,num-rows : number of rows in the matrix, see
+ bindings/input/matrix-keymap.txt
+ - keypad,num-columns : number of columns in the matrix, see
+ bindings/input/matrix-keymap.txt
+ - linux,keymap: the definition can be found in
+ bindings/input/matrix-keymap.txt
+ - linux,no-autorepeat: do no enable autorepeat feature.
+ - wakeup-source: use any event on keypad as wakeup event.
+ (Legacy property supported: "linux,wakeup")
+
+Example:
+
+tc35893@44 {

+Texas Instruments TWL family (twl4030) reset and power management module
+
+The power management module inside the TWL family provides several facilities
+to control the power resources, including power scripts. For now, the
+binding only supports the complete shutdown of the system after poweroff.
+
+Required properties:
+- compatible : must be one of the following
+ "ti,twl4030-power"
+ "ti,twl4030-power-reset"
+ "ti,twl4030-power-idle"
+ "ti,twl4030-power-idle-osc-off"
+
+The use of ti,twl4030-power-reset is recommended at least on
+3530 that needs a special configuration for warm reset to work.
+
+When using ti,twl4030-power-idle, the TI recommended configuration
+for idle modes is loaded to the tlw4030 PMIC.
+
+When using ti,twl4030-power-idle-osc-off, the TI recommended
+configuration is used with the external oscillator being shut
+down during off-idle. Note that this does not work on all boards
+depending on how the external oscillator is wired.
+
+Optional properties:
+
+- ti,system-power-controller: This indicates that TWL4030 is the
+ power supply master of the system. With this flag, the chip will
+ initiate an ACTIVE-to-OFF or SLEEP-to-OFF transition when the
+ system poweroffs.
+
+- ti,use_poweroff: Deprecated name for ti,system-power-controller
+
+Example:
+&i2c1 {
+ clock-frequency = <2600000>;
+
+ twl: twl@48 {

+
+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:
+- compatible : should be one of
+ "brcm,bcm7425-aon-ctrl"
+ "brcm,bcm7429-aon-ctrl"
+ "brcm,bcm7435-aon-ctrl" and
+ "brcm,brcmstb-aon-ctrl"
+- reg : the register start and length for the AON CTRL block
+
+Example:
+
+syscon@410000 {
+ compatible = "brcm,bcm7425-aon-ctrl", "brcm,brcmstb-aon-ctrl";
+ reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY.
+
+== MEMC (MEMory Controller)
+
+Represents a single memory controller instance.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-memc" and "simple-bus"
+- ranges : should contain the child address in the parent address
+ space, must be 0 here, and the register start and length of
+ the entire memory controller (including all sub nodes: DDR PHY,
+ arbiter, etc.)
+- #address-cells : must be 1
+- #size-cells : must be 1
+
+Example:
+
+ memory-controller@0 {
+ compatible = "brcm,brcmstb-memc", "simple-bus";
+ ranges = <0x0 0x0 0xa000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ memc-arb@1000 {
+ ...
+ };
+
+ memc-ddr@2000 {
+ ...
+ };
+
+ ddr-phy@6000 {
+ ...
+ };
+ };
+
+Should contain subnodes for any of the following relevant hardware resources:
+
+== DDR PHY control
+
+Control registers for this memory controller's DDR PHY.
+
+Required properties:
+- compatible : should contain one of these
+ "brcm,brcmstb-ddr-phy-v64.5"
+ "brcm,brcmstb-ddr-phy"
+
+- reg : the DDR PHY register range and length
+
+Example:
+
+ ddr-phy@6000 {
+ compatible = "brcm,brcmstb-ddr-phy-v64.5";
+ reg = <0x6000 0xc8>;
+ };
+
+== DDR memory controller sequencer
+
+Control registers for this memory controller's DDR memory sequencer
+
+Required properties:
+- compatible : should contain one of these
+ "brcm,bcm7425-memc-ddr"
+ "brcm,bcm7429-memc-ddr"
+ "brcm,bcm7435-memc-ddr" and
+ "brcm,brcmstb-memc-ddr"
+
+- reg : the DDR sequencer register range and length
+
+Example:
+
+ memc-ddr@2000 {
+ compatible = "brcm,bcm7425-memc-ddr", "brcm,brcmstb-memc-ddr";
+ reg = <0x2000 0x300>;
+ };
+
+== MEMC Arbiter
+
+The memory controller arbiter is responsible for memory clients allocation
+(bandwidth, priorities etc.) and needs to have its contents restored during
+deep sleep states (S3).
+
+Required properties:
+
+- compatible : should contain one of these
+ "brcm,brcmstb-memc-arb-v10.0.0.0"
+ "brcm,brcmstb-memc-arb"
+
+- reg : the DDR Arbiter register range and length
+
+Example:
+
+ memc-arb@1000 {
+ compatible = "brcm,brcmstb-memc-arb-v10.0.0.0";
+ reg = <0x1000 0x248>;
+ };
+
+== Timers
+
+The Broadcom STB chips contain a timer block with several general purpose
+timers that can be used.
+
+Required properties:
+
+- compatible : should contain one of:
+ "brcm,bcm7425-timers"
+ "brcm,bcm7429-timers"
+ "brcm,bcm7435-timers" and
+ "brcm,brcmstb-timers"
+- reg : the timers register range
+- interrupts : the interrupt line for this timer block
+
+Example:
+
+ timers: timer@4067c0 {
+ compatible = "brcm,bcm7425-timers", "brcm,brcmstb-timers";
+ reg = <0x4067c0 0x40>;
+ interrupts = <&periph_intc 19>;
+ };

+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Since the topology may
+be probed via CPS, it is not necessary to specify secondary CPUs. Required
+propertis:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mti,interaptiv".
+ - reg: CPU number.
+ - clocks: Must include the CPU clock. See ../../clock/clock-bindings.txt for
+ details on clock bindings.
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {

+ clocks = <&clk_core CLK_MIPS>;
+ };
+ };
+
+
+Boot protocol:
+--------------
+In accordance with the MIPS UHI specification[1], the bootloader must pass the
+following arguments to the kernel:
+ - $a0: -2.
+ - $a1: KSEG0 address of the flattened device-tree blob.

+Imagination University Program MIPSfpga
+=======================================
+
+Under the Imagination University Program, a microAptiv UP core has been
+released for academic usage.
+
+As we are dealing with a MIPS core instantiated on an FPGA, specifications
+are fluid and can be varied in RTL.
+
+This binding document is provided as baseline guidance for the example
+project provided by IMG.
+
+The example project runs on the Nexys4DDR board by Digilent powered by
+the ARTIX-7 FPGA by Xilinx.
+
+Relevant details about the example project and the Nexys4DDR board:
+
+- microAptiv UP core m14Kc
+- 50MHz clock speed
+- 128Mbyte DDR RAM at 0x0000_0000
+- 8Kbyte RAM at 0x1000_0000
+- axi_intc at 0x1020_0000
+- axi_uart16550 at 0x1040_0000
+- axi_gpio at 0x1060_0000
+- axi_i2c at 0x10A0_0000
+- custom_gpio at 0x10C0_0000
+- axi_ethernetlite at 0x10E0_0000
+- 8Kbyte BootRAM at 0x1FC0_0000
+
+Required properties:
+--------------------
+ - compatible: Must include "digilent,nexys4ddr","img,xilfpga".
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Required properties:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mips,m14Kc".
+ - reg: Must be <0>.
+ - clocks: phandle to ext clock for fixed-clock received by MIPS core.
+
+Example:
+
+ compatible = "img,xilfpga","digilent,nexys4ddr";
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "mips,m14Kc";
+ reg = <0>;
+ clocks = <&ext>;
+ };
+ };
+
+ ext: ext {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <50000000>;
+ };
+
+Boot protocol:
+--------------
+
+The BootRAM is a writeable "RAM" in FPGA at 0x1FC0_0000.
+This is for easy reprogrammibility via JTAG.
+
+The BootRAM initializes the cache and the axi_uart peripheral.
+
+DDR initialization is already handled by a HW IP block.
+
+When the example project bitstream is loaded, the cpu_reset button
+needs to be pressed.
+
+The bootram initializes the cache and axi_uart.
+Then outputs MIPSFPGA\n\r on the serial port on the Nexys4DDR board.
+
+At this point, the board is ready to load the Linux kernel
+vmlinux file via JTAG.

+Lantiq XWAY SoC RCU binding
+===========================
+
+This binding describes the RCU (reset controller unit) multifunction device,
+where each sub-device has its own set of registers.
+
+The RCU register range is used for multiple purposes. Mostly one device
+uses one or multiple register exclusively, but for some registers some
+bits are for one driver and some other bits are for a different driver.
+With this patch all accesses to the RCU registers will go through
+syscon.
+
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible : The first and second values must be:
+ "lantiq,xrx200-rcu", "simple-mfd", "syscon"
+- reg : The address and length of the system control registers
+
+
+-------------------------------------------------------------------------------
+Example of the RCU bindings on a xRX200 SoC:
+ rcu0: rcu@203000 {
+ compatible = "lantiq,xrx200-rcu", "simple-mfd", "syscon";
+ reg = <0x203000 0x100>;
+ ranges = <0x0 0x203000 0x100>;
+ big-endian;
+
+ reset0: reset-controller@10 {
+ compatible = "lantiq,xrx200-reset";
+ reg = <0x10 4>, <0x14 4>;
+
+ #reset-cells = <2>;
+ };
+
+ reset1: reset-controller@48 {
+ compatible = "lantiq,xrx200-reset";
+ reg = <0x48 4>, <0x24 4>;
+
+ #reset-cells = <2>;
+ };
+
+ usb_phy0: usb2-phy@18 {
+ compatible = "lantiq,xrx200-usb2-phy";
+ reg = <0x18 4>, <0x38 4>;
+
+ resets = <&reset1 4 4>, <&reset0 4 4>;
+ reset-names = "phy", "ctrl";
+ #phy-cells = <0>;
+ };
+
+ usb_phy1: usb2-phy@34 {

+ reg = <0x34 4>, <0x3C 4>;
+
+ resets = <&reset1 5 4>, <&reset0 4 4>;
+ reset-names = "phy", "ctrl";
+ #phy-cells = <0>;
+ };
+
+ reboot@10 {
+ compatible = "syscon-reboot";
+ reg = <0x10 4>;
+
+ regmap = <&rcu0>;
+ offset = <0x10>;
+ mask = <0x40000000>;

+* ASPEED AST2400 and AST2500 coprocessor interrupt controller
+
+This file describes the bindings for the interrupt controller present
+in the AST2400 and AST2500 BMC SoCs which provides interrupt to the
+ColdFire coprocessor.
+
+It is not a normal interrupt controller and it would be rather
+inconvenient to create an interrupt tree for it as it somewhat shares
+some of the same sources as the main ARM interrupt controller but with
+different numbers.
+
+The AST2500 supports a SW generated interrupt
+
+Required properties:
+- reg: address and length of the register for the device.
+- compatible: "aspeed,cvic" and one of:
+ "aspeed,ast2400-cvic"
+ or
+ "aspeed,ast2500-cvic"
+
+- valid-sources: One cell, bitmap of supported sources for the implementation
+
+Optional properties;
+- copro-sw-interrupts: List of interrupt numbers that can be used as
+ SW interrupts from the ARM to the coprocessor.
+ (AST2500 only)
+
+Example:
+
+ cvic: copro-interrupt-controller@1e6c2000 {
+ compatible = "aspeed,ast2500-cvic";
+ valid-sources = <0xffffffff>;
+ copro-sw-interrupts = <1>;
+ reg = <0x1e6c2000 0x80>;

+======================================================================
+Device tree bindings for Aspeed AST2400/AST2500 PCI-to-AHB Bridge Control Driver
+======================================================================
+
+The bridge is available on platforms with the VGA enabled on the Aspeed device.
+In this case, the host has access to a 64KiB window into all of the BMC's
+memory. The BMC can disable this bridge. If the bridge is enabled, the host
+has read access to all the regions of memory, however the host only has read
+and write access depending on a register controlled by the BMC.
+
+Required properties:
+===================
+
+ - compatible: must be one of:
+ - "aspeed,ast2400-p2a-ctrl"
+ - "aspeed,ast2500-p2a-ctrl"
+
+Optional properties:
+===================
+
+- reg: A hint for the memory regions associated with the P2A controller
+- memory-region: A phandle to a reserved_memory region to be used for the PCI
+ to AHB mapping
+
+The p2a-control node should be the child of a syscon node with the required
+property:
+
+- compatible : Should be one of the following:
+ "aspeed,ast2400-scu", "syscon", "simple-mfd"
+ "aspeed,ast2500-scu", "syscon", "simple-mfd"
+
+Example
+===================
+
+g4 Example
+----------
+
+syscon: scu@1e6e2000 {
+ compatible = "aspeed,ast2400-scu", "syscon", "simple-mfd";
+ reg = <0x1e6e2000 0x1a8>;

+* Atmel SSC driver.
+
+Required properties:
+- compatible: "atmel,at91rm9200-ssc" or "atmel,at91sam9g45-ssc"
+ - atmel,at91rm9200-ssc: support pdc transfer
+ - atmel,at91sam9g45-ssc: support dma transfer
+- reg: Should contain SSC registers location and length
+- interrupts: Should contain SSC interrupt
+- clock-names: tuple listing input clock names.
+ Required elements: "pclk"
+- clocks: phandles to input clocks.
+
+
+Required properties for devices compatible with "atmel,at91sam9g45-ssc":
+- dmas: DMA specifier, consisting of a phandle to DMA controller node,
+ the memory interface and SSC DMA channel ID (for tx and rx).
+ See Documentation/devicetree/bindings/dma/atmel-dma.txt for details.
+- dma-names: Must be "tx", "rx".
+
+Optional properties:
+ - atmel,clk-from-rk-pin: bool property.
+ - When SSC works in slave mode, according to the hardware design, the
+ clock can get from TK pin, and also can get from RK pin. So, add
+ this parameter to choose where the clock from.
+ - By default the clock is from TK pin, if the clock from RK pin, this
+ property is needed.
+ - #sound-dai-cells: Should contain <0>.
+ - This property makes the SSC into an automatically registered DAI.
+
+Examples:
+- PDC transfer:

+* Freescale Management Complex
+
+The Freescale Management Complex (fsl-mc) is a hardware resource
+manager that manages specialized hardware objects used in
+network-oriented packet processing applications. After the fsl-mc
+block is enabled, pools of hardware resources are available, such as
+queues, buffer pools, I/O interfaces. These resources are building
+blocks that can be used to create functional hardware objects/devices
+such as network interfaces, crypto accelerator instances, L2 switches,
+etc.
+
+For an overview of the DPAA2 architecture and fsl-mc bus see:
+Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst
+
+As described in the above overview, all DPAA2 objects in a DPRC share the
+same hardware "isolation context" and a 10-bit value called an ICID
+(isolation context id) is expressed by the hardware to identify
+the requester.
+
+The generic 'iommus' property is insufficient to describe the relationship
+between ICIDs and IOMMUs, so an iommu-map property is used to define
+the set of possible ICIDs under a root DPRC and how they map to
+an IOMMU.
+
+For generic IOMMU bindings, see
+Documentation/devicetree/bindings/iommu/iommu.txt.
+
+For arm-smmu binding, see:
+Documentation/devicetree/bindings/iommu/arm,smmu.yaml.
+
+The MSI writes are accompanied by sideband data which is derived from the ICID.
+The msi-map property is used to associate the devices with both the ITS
+controller and the sideband data which accompanies the writes.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+For GICv3 and GIC ITS bindings, see:
+Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml.
+
+Required properties:
+
+ - compatible
+ Value type: <string>
+ Definition: Must be "fsl,qoriq-mc". A Freescale Management Complex
+ compatible with this binding must have Block Revision
+ Registers BRR1 and BRR2 at offset 0x0BF8 and 0x0BFC in
+ the MC control register region.
+
+ - reg
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies one or two regions
+ defining the MC's registers:
+
+ -the first region is the command portal for the
+ this machine and must always be present
+
+ -the second region is the MC control registers. This
+ region may not be present in some scenarios, such
+ as in the device tree presented to a virtual machine.
+
+ - ranges
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Defines the mapping between the child
+ MC address space and the parent system address space.
+
+ The MC address space is defined by 3 components:
+ <region type> <offset hi> <offset lo>
+
+ Valid values for region type are
+ 0x0 - MC portals
+ 0x1 - QBMAN portals
+
+ - #address-cells
+ Value type: <u32>
+ Definition: Must be 3. (see definition in 'ranges' property)
+
+ - #size-cells
+ Value type: <u32>
+ Definition: Must be 1.
+
+Sub-nodes:
+
+ The fsl-mc node may optionally have dpmac sub-nodes that describe
+ the relationship between the Ethernet MACs which belong to the MC
+ and the Ethernet PHYs on the system board.
+
+ The dpmac nodes must be under a node named "dpmacs" which contains
+ the following properties:
+
+ - #address-cells
+ Value type: <u32>
+ Definition: Must be present if dpmac sub-nodes are defined and must
+ have a value of 1.
+
+ - #size-cells
+ Value type: <u32>
+ Definition: Must be present if dpmac sub-nodes are defined and must
+ have a value of 0.
+
+ These nodes must have the following properties:
+
+ - compatible
+ Value type: <string>
+ Definition: Must be "fsl,qoriq-mc-dpmac".
+
+ - reg
+ Value type: <prop-encoded-array>
+ Definition: Specifies the id of the dpmac.
+
+ - phy-handle
+ Value type: <phandle>
+ Definition: Specifies the phandle to the PHY device node associated
+ with the this dpmac.
+Optional properties:
+
+- iommu-map: Maps an ICID to an IOMMU and associated iommu-specifier
+ data.
+
+ The property is an arbitrary number of tuples of
+ (icid-base,iommu,iommu-base,length).
+
+ Any ICID i in the interval [icid-base, icid-base + length) is
+ associated with the listed IOMMU, with the iommu-specifier
+ (i - icid-base + iommu-base).
+
+- msi-map: Maps an ICID to a GIC ITS and associated msi-specifier
+ data.
+
+ The property is an arbitrary number of tuples of
+ (icid-base,gic-its,msi-base,length).
+
+ Any ICID in the interval [icid-base, icid-base + length) is
+ associated with the listed GIC ITS, with the msi-specifier
+ (i - icid-base + msi-base).
+
+Deprecated properties:
+
+ - msi-parent
+ Value type: <phandle>
+ Definition: Describes the MSI controller node handling message
+ interrupts for the MC. When there is no translation
+ between the ICID and deviceID this property can be used
+ to describe the MSI controller used by the devices on the
+ mc-bus.
+ The use of this property for mc-bus is deprecated. Please
+ use msi-map.

+ on a OLPC XO-1.75 laptop computer.
+
+ The embedded controller requires the SPI controller driver to signal
+ readiness to receive a transfer (that is, when TX FIFO contains the

+* Xilinx SDFEC(16nm) IP *
+
+The Soft Decision Forward Error Correction (SDFEC) Engine is a Hard IP block
+which provides high-throughput LDPC and Turbo Code implementations.
+The LDPC decode & encode functionality is capable of covering a range of
+customer specified Quasi-cyclic (QC) codes. The Turbo decode functionality
+principally covers codes used by LTE. The FEC Engine offers significant
+power and area savings versus implementations done in the FPGA fabric.
+
+
+Required properties:
+- compatible: Must be "xlnx,sd-fec-1.1"
+- clock-names : List of input clock names from the following:
+ - "core_clk", Main processing clock for processing core (required)
+ - "s_axi_aclk", AXI4-Lite memory-mapped slave interface clock (required)
+ - "s_axis_din_aclk", DIN AXI4-Stream Slave interface clock (optional)
+ - "s_axis_din_words-aclk", DIN_WORDS AXI4-Stream Slave interface clock (optional)
+ - "s_axis_ctrl_aclk", Control input AXI4-Stream Slave interface clock (optional)
+ - "m_axis_dout_aclk", DOUT AXI4-Stream Master interface clock (optional)
+ - "m_axis_dout_words_aclk", DOUT_WORDS AXI4-Stream Master interface clock (optional)

+ location and length.
+- xlnx,sdfec-code : Should contain "ldpc" or "turbo" to describe the codes
+ being used.
+- xlnx,sdfec-din-words : A value 0 indicates that the DIN_WORDS interface is
+ driven with a fixed value and is not present on the device, a value of 1
+ configures the DIN_WORDS to be block based, while a value of 2 configures the
+ DIN_WORDS input to be supplied for each AXI transaction.
+- xlnx,sdfec-din-width : Configures the DIN AXI stream where a value of 1
+ configures a width of "1x128b", 2 a width of "2x128b" and 4 configures a width
+ of "4x128b".
+- xlnx,sdfec-dout-words : A value 0 indicates that the DOUT_WORDS interface is
+ driven with a fixed value and is not present on the device, a value of 1
+ configures the DOUT_WORDS to be block based, while a value of 2 configures the

+* Amlogic Meson6, Meson8 and Meson8b SDIO/MMC controller
+
+The highspeed MMC host controller on Amlogic SoCs provides an interface
+for MMC, SD, SDIO and SDHC types of memory cards.
+
+Supported maximum speeds are the ones of the eMMC standard 4.41 as well
+as the speed of SD standard 2.0.
+
+The hardware provides an internal "mux" which allows up to three slots
+to be controlled. Only one slot can be accessed at a time.
+
+Required properties:
+ - compatible : must be one of
+ - "amlogic,meson8-sdio"
+ - "amlogic,meson8b-sdio"
+ along with the generic "amlogic,meson-mx-sdio"
+ - reg : mmc controller base registers
+ - interrupts : mmc controller interrupt
+ - #address-cells : must be 1
+ - size-cells : must be 0
+ - clocks : phandle to clock providers
+ - clock-names : must contain "core" and "clkin"
+
+Required child nodes:
+A node for each slot provided by the MMC controller is required.
+NOTE: due to a driver limitation currently only one slot (= child node)
+ is supported!
+
+Required properties on each child node (= slot):
+ - compatible : must be "mmc-slot" (see mmc.txt within this directory)
+ - reg : the slot (or "port") ID
+
+Optional properties on each child node (= slot):
+ - bus-width : must be 1 or 4 (8-bit bus is not supported)
+ - for cd and all other additional generic mmc parameters
+ please refer to mmc.txt within this directory
+
+Examples:
+ mmc@c1108c20 {
+ compatible = "amlogic,meson8-sdio", "amlogic,meson-mx-sdio";
+ reg = <0xc1108c20 0x20>;
+ interrupts = <0 28 1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&clkc CLKID_SDIO>, <&clkc CLKID_CLK81>;
+ clock-names = "core", "clkin";
+
+ slot@1 {
+ compatible = "mmc-slot";
+ reg = <1>;
+
+ bus-width = <4>;
+ };
+ };

+* Atmel High Speed MultiMedia Card Interface
+
+This controller on atmel products provides an interface for MMC, SD and SDIO
+types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the atmel-mci driver.
+
+1) MCI node
+
+Required properties:
+- compatible: should be "atmel,hsmci"
+- #address-cells: should be one. The cell is the slot id.
+- #size-cells: should be zero.
+- at least one slot node
+- clock-names: tuple listing input clock names.
+ Required elements: "mci_clk"
+- clocks: phandles to input clocks.
+
+The node contains child nodes for each slot that the platform uses
+
+Example MCI node:
+
+mmc0: mmc@f0008000 {
+ compatible = "atmel,hsmci";
+ reg = <0xf0008000 0x600>;
+ interrupts = <12 4>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clock-names = "mci_clk";
+ clocks = <&mci0_clk>;
+
+ [ child node definitions...]
+};
+
+2) slot nodes
+
+Required properties:
+- reg: should contain the slot id.
+- bus-width: number of data lines connected to the controller
+
+Optional properties:
+- cd-gpios: specify GPIOs for card detection
+- cd-inverted: invert the value of external card detect gpio line
+- wp-gpios: specify GPIOs for write protection
+
+Example slot node:
+
+slot@0 {
+ reg = <0>;
+ bus-width = <4>;
+ cd-gpios = <&pioD 15 0>
+ cd-inverted;
+};
+
+Example full MCI node:

+ #size-cells = <0>;
+ slot@0 {
+ reg = <0>;
+ bus-width = <4>;
+ cd-gpios = <&pioD 15 0>
+ cd-inverted;
+ };
+ slot@1 {
+ reg = <1>;
+ bus-width = <4>;
+ };

+* Cavium Octeon & ThunderX MMC controller
+
+The highspeed MMC host controller on Caviums SoCs provides an interface
+for MMC and SD types of memory cards.
+
+Supported maximum speeds are the ones of the eMMC standard 4.41 as well
+as the speed of SD standard 4.0. Only 3.3 Volt is supported.
+
+Required properties:
+ - compatible : should be one of:
+ cavium,octeon-6130-mmc
+ cavium,octeon-7890-mmc
+ cavium,thunder-8190-mmc
+ cavium,thunder-8390-mmc
+ mmc-slot
+ - reg : mmc controller base registers
+ - clocks : phandle
+
+Optional properties:
+ - for cd, bus-width and additional generic mmc parameters
+ please refer to mmc.txt within this directory
+ - cavium,cmd-clk-skew : number of coprocessor clocks before sampling command
+ - cavium,dat-clk-skew : number of coprocessor clocks before sampling data
+
+Deprecated properties:
+- spi-max-frequency : use max-frequency instead
+- cavium,bus-max-width : use bus-width instead
+- power-gpios : use vmmc-supply instead
+- cavium,octeon-6130-mmc-slot : use mmc-slot instead
+
+Examples:

+* Freescale Enhanced Secure Digital Host Controller (eSDHC)
+
+The Enhanced Secure Digital Host Controller provides an interface
+for MMC, SD, and SDIO types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the sdhci-esdhc driver.
+
+Required properties:
+ - compatible : should be "fsl,esdhc", or "fsl,<chip>-esdhc".
+ Possible compatibles for PowerPC:
+ "fsl,mpc8536-esdhc"
+ "fsl,mpc8378-esdhc"
+ "fsl,p2020-esdhc"
+ "fsl,p4080-esdhc"
+ "fsl,t1040-esdhc"
+ "fsl,t4240-esdhc"
+ Possible compatibles for ARM:
+ "fsl,ls1012a-esdhc"
+ "fsl,ls1028a-esdhc"
+ "fsl,ls1088a-esdhc"
+ "fsl,ls1043a-esdhc"
+ "fsl,ls1046a-esdhc"
+ "fsl,ls2080a-esdhc"
+ - clock-frequency : specifies eSDHC base clock frequency.
+
+Optional properties:
+ - sdhci,wp-inverted : specifies that eSDHC controller reports
+ inverted write-protect state; New devices should use the generic
+ "wp-inverted" property.
+ - sdhci,1-bit-only : specifies that a controller can only handle
+ 1-bit data transfers. New devices should use the generic
+ "bus-width = <1>" property.
+ - sdhci,auto-cmd12: specifies that a controller can only handle auto
+ CMD12.
+ - voltage-ranges : two cells are required, first cell specifies minimum
+ slot voltage (mV), second cell specifies maximum slot voltage (mV).
+ Several ranges could be specified.
+ - little-endian : If the host controller is little-endian mode, specify
+ this property. The default endian mode is big-endian.
+
+Example:
+
+sdhci@2e000 {
+ compatible = "fsl,mpc8378-esdhc", "fsl,esdhc";

+
+Read synopsys-dw-mshc.txt for more details
+
+The Synopsys designware mobile storage host controller is used to interface
+a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
+differences between the core Synopsys dw mshc controller properties described
+by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific
+extensions to the Synopsys Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be one of the following.
+ - "hisilicon,hi3660-dw-mshc": for controllers with hi3660 specific extensions.
+ - "hisilicon,hi3670-dw-mshc", "hisilicon,hi3660-dw-mshc": for controllers
+ with hi3670 specific extensions.

+description: |
+ These properties are common to multiple MMC host controllers. Any host
+ that requires the respective functionality should implement them using
+ these definitions.
+
+ It is possible to assign a fixed index mmcN to an MMC host controller
+ (and the corresponding mmcblkN devices) by defining an alias in the
+ /aliases device tree node.

+ # *NOTE* on CD and WP polarity. To use common for all SD/MMC host
+ # controllers line polarity properties, we have to fix the meaning
+ # of the "normal" and "inverted" line levels. We choose to follow
+ # the SDHCI standard, which specifies both those lines as "active
+ # low." Therefore, using the "cd-inverted" property means, that the
+ # CD line is active high, i.e. it is high, when a card is
+ # inserted. Similar logic applies to the "wp-inverted" property.
+ #
+ # CD and WP lines can be implemented on the hardware in one of two
+ # ways: as GPIOs, specified in cd-gpios and wp-gpios properties, or
+ # as dedicated pins. Polarity of dedicated pins can be specified,
+ # using *-inverted properties. GPIO polarity can also be specified
+ # using the GPIO_ACTIVE_LOW flag. This creates an ambiguity in the
+ # latter case. We choose to use the XOR logic for GPIO CD and WP
+ # lines. This means, the two properties are "superimposed," for
+ # example leaving the GPIO_ACTIVE_LOW flag clear and specifying the
+ # respective *-inverted property property results in a
+ # double-inversion and actually means the "normal" line polarity is
+ # in effect.

+* Atmel SDHCI controller
+
+This file documents the differences between the core properties in
+Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
+sdhci-of-at91 driver.
+
+Required properties:
+- compatible: Must be "atmel,sama5d2-sdhci" or "microchip,sam9x60-sdhci"
+ or "microchip,sam9x7-sdhci", "microchip,sam9x60-sdhci".
+- clocks: Phandlers to the clocks.
+- clock-names: Must be "hclock", "multclk", "baseclk" for
+ "atmel,sama5d2-sdhci".
+ Must be "hclock", "multclk" for "microchip,sam9x60-sdhci".
+ Must be "hclock", "multclk" for "microchip,sam9x7-sdhci".
+
+Optional properties:
+- assigned-clocks: The same with "multclk".
+- assigned-clock-rates The rate of "multclk" in order to not rely on the
+ gck configuration set by previous components.
+- microchip,sdcal-inverted: when present, polarity on the SDCAL SoC pin is
+ inverted. The default polarity for this signal is described in the datasheet.
+ For instance on SAMA5D2, the pin is usually tied to the GND with a resistor
+ and a capacitor (see "SDMMC I/O Calibration" chapter).
+
+Example:
+
+mmc0: sdio-host@a0000000 {
+ compatible = "atmel,sama5d2-sdhci";
+ reg = <0xa0000000 0x300>;

+ clocks = <&sdmmc0_hclk>, <&sdmmc0_gclk>, <&main>;
+ clock-names = "hclock", "multclk", "baseclk";
+ assigned-clocks = <&sdmmc0_gclk>;
+ assigned-clock-rates = <480000000>;

+
+Required properties:
+- compatible: "socionext,milbeaut-m10v-sdhci-3.0"
+- clocks: Must contain an entry for each entry in clock-names. It is a
+ list of phandles and clock-specifier pairs.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Should contain the following two entries:

+ "core" - core clock for sdhci controller
+
+Optional properties:
+- fujitsu,cmd-dat-delay-select: boolean property indicating that this host
+ requires the CMD_DAT_DELAY control to be enabled.

+* TI OMAP SDHCI Controller
+
+Refer to mmc.txt for standard MMC bindings.
+
+For UHS devices which require tuning, the device tree should have a "cpu_thermal" node which maps to the appropriate thermal zone. This is used to get the temperature of the zone during tuning.
+
+Required properties:
+- compatible: Should be "ti,omap2430-sdhci" for omap2430 controllers
+ Should be "ti,omap3-sdhci" for omap3 controllers
+ Should be "ti,omap4-sdhci" for omap4 and ti81 controllers
+ Should be "ti,omap5-sdhci" for omap5 controllers
+ Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
+ Should be "ti,k2g-sdhci" for K2G
+ Should be "ti,am335-sdhci" for am335x controllers
+ Should be "ti,am437-sdhci" for am437x controllers
+- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1
+ (Not required for K2G).
+- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50",
+ "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104",
+ "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11",
+ "hs200_1_8v",
+- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
+
+Optional properties:
+- dmas: List of DMA specifiers with the controller specific format as described
+ in the generic DMA client binding. A tx and rx specifier is required.
+- dma-names: List of DMA request names. These strings correspond 1:1 with the
+ DMA specifiers listed in dmas. The string naming is to be "tx"
+ and "rx" for TX and RX DMA requests, respectively.
+
+Deprecated properties:
+- ti,non-removable: Compatible with the generic non-removable property
+
+Example:
+ mmc1: mmc@4809c000 {
+ compatible = "ti,dra7-sdhci";

+* Spreadtrum SDHCI controller (sdhci-sprd)
+
+The Secure Digital (SD) Host controller on Spreadtrum SoCs provides an interface
+for MMC, SD and SDIO types of cards.
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the sdhci-sprd driver.

+- clocks: Should contain phandle for the clock feeding the SDHCI controller
+- clock-names: Should contain the following:
+ "sdio" - SDIO source clock (required)
+ "enable" - gate clock which used for enabling/disabling the device (required)
+ "2x_enable" - gate clock controlling the device for some special platforms (optional)
+
+Optional properties:

+- pinctrl-1: should contain uhs mode pin control
+
+PHY DLL delays are used to delay the data valid window, and align the window
+to sampling clock. PHY DLL delays can be configured by following properties,
+and each property contains 4 cells which are used to configure the clock data
+write line delay value, clock read command line delay value, clock read data
+positive edge delay value and clock read data negative edge delay value.
+Each cell's delay value unit is cycle of the PHY clock.
+
+- sprd,phy-delay-legacy: Delay value for legacy timing.
+- sprd,phy-delay-sd-highspeed: Delay value for SD high-speed timing.
+- sprd,phy-delay-sd-uhs-sdr50: Delay value for SD UHS SDR50 timing.

+ family.
+ See: Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- bus-width: Number of data lines.
+ See: Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- max-frequency: Can be 200MHz, 100MHz or 50MHz (default) and used for
+ configuring the CCONFIG3 in the mmcss.
+ See: Documentation/devicetree/bindings/mmc/mmc.txt.
+

+* TI Highspeed MMC host controller for OMAP and 66AK2G family.
+
+The Highspeed MMC Host Controller on TI OMAP and 66AK2G family
+provides an interface for MMC, SD, and SDIO types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the omap_hsmmc driver.
+
+Required properties:
+--------------------
+- compatible:
+ Should be "ti,omap2-hsmmc", for OMAP2 controllers
+ Should be "ti,omap3-hsmmc", for OMAP3 controllers
+ Should be "ti,omap3-pre-es3-hsmmc" for OMAP3 controllers pre ES3.0
+ Should be "ti,omap4-hsmmc", for OMAP4 controllers
+ Should be "ti,am33xx-hsmmc", for AM335x controllers
+ Should be "ti,k2g-hsmmc", "ti,omap4-hsmmc" for 66AK2G controllers.
+
+SoC specific required properties:
+---------------------------------
+The following are mandatory properties for OMAPs, AM33xx and AM43xx SoCs only:
+- ti,hwmods: Must be "mmc<n>", n is controller instance starting 1.
+
+The following are mandatory properties for 66AK2G SoCs only:
+- power-domains:Should contain a phandle to a PM domain provider node
+ and an args specifier containing the MMC device id
+ value. This property is as per the binding,
+ Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
+- clocks: Must contain an entry for each entry in clock-names. Should
+ be defined as per the he appropriate clock bindings consumer
+ usage in Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
+- clock-names: Shall be "fck" for the functional clock,
+ and "mmchsdb_fck" for the debounce clock.
+
+
+Optional properties:
+--------------------
+- ti,dual-volt: boolean, supports dual voltage cards
+- <supply-name>-supply: phandle to the regulator device tree node
+ "supply-name" examples are "vmmc",
+ "vmmc_aux"(deprecated)/"vqmmc" etc
+- ti,non-removable: non-removable slot (like eMMC)
+- ti,needs-special-reset: Requires a special softreset sequence
+- ti,needs-special-hs-handling: HSMMC IP needs special setting
+ for handling High Speed
+- dmas: List of DMA specifiers with the controller specific
+ format as described in the generic DMA client
+ binding. A tx and rx specifier is required.
+- dma-names: List of DMA request names. These strings correspond
+ 1:1 with the DMA specifiers listed in dmas.
+ The string naming is to be "rx" and "tx" for
+ RX and TX DMA requests, respectively.
+
+Examples:
+
+[hwmod populated DMA resources]
+
+ mmc1: mmc@4809c000 {
+ compatible = "ti,omap4-hsmmc";
+ reg = <0x4809c000 0x400>;
+ ti,hwmods = "mmc1";
+ ti,dual-volt;
+ bus-width = <4>;
+ vmmc-supply = <&vmmc>; /* phandle to regulator node */
+ ti,non-removable;
+ };
+
+[generic DMA request binding]
+
+ mmc1: mmc@4809c000 {
+ compatible = "ti,omap4-hsmmc";
+ reg = <0x4809c000 0x400>;
+ ti,hwmods = "mmc1";
+ ti,dual-volt;
+ bus-width = <4>;
+ vmmc-supply = <&vmmc>; /* phandle to regulator node */
+ ti,non-removable;
+ dmas = <&edma 24
+ &edma 25>;
+ dma-names = "tx", "rx";
+ };
+
+[workaround for missing swakeup on am33xx]
+
+This SOC is missing the swakeup line, it will not detect SDIO irq
+while in suspend.
+
+ ------
+ | PRCM |
+ ------
+ ^ |
+ swakeup | | fclk
+ | v
+ ------ ------- -----
+ | card | -- CIRQ --> | hsmmc | -- IRQ --> | CPU |
+ ------ ------- -----
+
+In suspend the fclk is off and the module is dysfunctional. Even register reads
+will fail. A small logic in the host will request fclk restore, when an
+external event is detected. Once the clock is restored, the host detects the
+event normally. Since am33xx doesn't have this line it never wakes from
+suspend.
+
+The workaround is to reconfigure the dat1 line as a GPIO upon suspend. To make
+this work, we need to set the named pinctrl states "default" and "idle".
+Prepare idle to remux dat1 as a gpio, and default to remux it back as sdio
+dat1. The MMC driver will then toggle between idle and default state during
+runtime.
+
+In summary:
+1. select matching 'compatible' section, see example below.
+2. specify pinctrl states "default" and "idle", "sleep" is optional.
+3. specify the gpio irq used for detecting sdio irq in suspend
+
+If configuration is incomplete, a warning message is emitted "falling back to
+polling". Also check the "sdio irq mode" in /sys/kernel/debug/mmc0/regs. Mind
+not every application needs SDIO irq, e.g. MMC cards.
+
+ mmc1: mmc@48060100 {
+ compatible = "ti,am33xx-hsmmc";
+ ...
+ pinctrl-names = "default", "idle", "sleep"
+ pinctrl-0 = <&mmc1_pins>;
+ pinctrl-1 = <&mmc1_idle>;
+ pinctrl-2 = <&mmc1_sleep>;
+ ...
+ interrupts-extended = <&intc 64 &gpio2 28 IRQ_TYPE_LEVEL_LOW>;
+ };
+
+ mmc1_idle : pinmux_cirq_pin {
+ pinctrl-single,pins = <
+ 0x0f8 0x3f /* GPIO2_28 */
+ >;

+Atmel NAND flash controller bindings
+
+The NAND flash controller node should be defined under the EBI bus (see
+Documentation/devicetree/bindings/memory-controllers/atmel,ebi.txt).
+One or several NAND devices can be defined under this NAND controller.
+The NAND controller might be connected to an ECC engine.
+
+* NAND controller bindings:
+
+Required properties:
+- compatible: should be one of the following
+ "atmel,at91rm9200-nand-controller"
+ "atmel,at91sam9260-nand-controller"
+ "atmel,at91sam9261-nand-controller"
+ "atmel,at91sam9g45-nand-controller"
+ "atmel,sama5d3-nand-controller"
+ "microchip,sam9x60-nand-controller"
+- ranges: empty ranges property to forward EBI ranges definitions.
+- #address-cells: should be set to 2.
+- #size-cells: should be set to 1.
+- atmel,nfc-io: phandle to the NFC IO block. Only required for sama5d3
+ controllers.
+- atmel,nfc-sram: phandle to the NFC SRAM block. Only required for sama5d3
+ controllers.
+
+Optional properties:
+- ecc-engine: phandle to the PMECC block. Only meaningful if the SoC embeds
+ a PMECC engine.
+
+* NAND device/chip bindings:
+
+Required properties:
+- reg: describes the CS lines assigned to the NAND device. If the NAND device
+ exposes multiple CS lines (multi-dies chips), your reg property will
+ contain X tuples of 3 entries.
+ 1st entry: the CS line this NAND chip is connected to
+ 2nd entry: the base offset of the memory region assigned to this
+ device (always 0)
+ 3rd entry: the memory region size (always 0x800000)
+
+Optional properties:
+- rb-gpios: the GPIO(s) used to check the Ready/Busy status of the NAND.
+- cs-gpios: the GPIO(s) used to control the CS line.
+- det-gpios: the GPIO used to detect if a Smartmedia Card is present.
+- atmel,rb: an integer identifying the native Ready/Busy pin. Only meaningful
+ on sama5 SoCs.
+
+All generic properties are described in the generic yaml files under
+Documentation/devicetree/bindings/mtd/.

+ "atmel,sama5d4-pmecc"
+ "atmel,sama5d2-pmecc"
+ "microchip,sam9x60-pmecc"
+- reg: should contain 2 register ranges. The first one is pointing to the PMECC
+ block, and the second one to the PMECC_ERRLOC block.
+
+* SAMA5 NFC I/O bindings:
+
+SAMA5 SoCs embed an advanced NAND controller logic to automate READ/WRITE page
+operations. This interface to this logic is placed in a separate I/O range and
+should thus have its own DT node.

+
+description: |
+ The Broadcom Set-Top Box NAND controller supports low-level access to raw NAND
+ flash chips. It has a memory-mapped register interface for both control
+ registers and for its data input/output buffer. On some SoCs, this controller
+ is paired with a custom DMA engine (inventively named "Flash DMA") which
+ supports basic PROGRAM and READ functions, among other features.
+
+ This controller was originally designed for STB SoCs (BCM7xxx) but is now
+ available on a variety of Broadcom SoCs, including some BCM3xxx, BCM63xx, and
+ iProc/Cygnus. Its history includes several similar (but not fully register
+ compatible) versions.
+
+ -- Additional SoC-specific NAND controller properties --
+
+ The NAND controller is integrated differently on the variety of SoCs on which
+ it is found. Part of this integration involves providing status and enable
+ bits with which to control the 8 exposed NAND interrupts, as well as hardware
+ for configuring the endianness of the data bus. On some SoCs, these features
+ are handled via standard, modular components (e.g., their interrupts look like
+ a normal IRQ chip), but on others, they are controlled in unique and
+ interesting ways, sometimes with registers that lump multiple NAND-related
+ functions together. The former case can be described simply by the standard
+ interrupts properties in the main controller node. But for the latter
+ exceptional cases, we define additional 'compatible' properties and associated
+ register resources within the NAND controller node above.

+ strapped to LOW, the status register nonvolatile bits become read-only and
+ the WRITE STATUS REGISTER operation will not execute. The only way to exit
+ this hardware-protected mode is to drive WP# HIGH. If the WP# signal of the
+ flash device is not connected or is wrongly tied to GND (that includes internal
+ pull-downs) then status register permanently becomes read-only as the SRWD bit

+Macronix NANDs Device Tree Bindings
+-----------------------------------
+
+Macronix NANDs support randomizer operation for scrambling user data,
+which can be enabled with a SET_FEATURE. The penalty when using the
+randomizer are subpage accesses prohibited and more time period needed
+for program operation, i.e., tPROG 300us to 340us (randomizer enabled).
+Enabling the randomizer is a one time persistent and non reversible
+operation.
+
+For more high-reliability concern, if subpage write is not available
+with hardware ECC and not enabled at UBI level, then enabling the
+randomizer is recommended by default by adding a new specific property
+in children nodes.
+
+Required NAND chip properties in children mode:
+- randomizer enable: should be "mxic,enable-randomizer-otp"
+
+Example:
+
+ nand: nand-controller@unit-address {
+
+ nand@0 {
+ reg = <0>;
+ mxic,enable-randomizer-otp;
+ };

+* NXP SPI Flash Interface (SPIFI)
+
+NXP SPIFI is a specialized SPI interface for serial Flash devices.
+It supports one Flash device with 1-, 2- and 4-bits width in SPI
+mode 0 or 3. The controller operates in either command or memory
+mode. In memory mode the Flash is accessible from the CPU as
+normal memory.
+
+Required properties:
+ - compatible : Should be "nxp,lpc1773-spifi"
+ - reg : the first contains the register location and length,
+ the second contains the memory mapping address and length
+ - reg-names: Should contain the reg names "spifi" and "flash"
+ - interrupts : Should contain the interrupt for the device
+ - clocks : The clocks needed by the SPIFI controller
+ - clock-names : Should contain the clock names "spifi" and "reg"
+
+Optional properties:
+ - resets : phandle + reset specifier
+
+The SPI Flash must be a child of the SPIFI node and must have a
+compatible property as specified in bindings/mtd/jedec,spi-nor.txt
+
+Optionally it can also contain the following properties.
+ - spi-cpol : Controller only supports mode 0 and 3 so either
+ both spi-cpol and spi-cpha should be present or
+ none of them
+ - spi-cpha : See above
+ - spi-rx-bus-width : Used to select how many pins that are used
+ for input on the controller
+
+See bindings/spi/spi-bus.txt for more information.

+title: Broadcom BCM47xx Partitions
+
+description: |
+ Broadcom is one of hardware manufacturers providing SoCs (BCM47xx) used in
+ home routers. Their BCM947xx boards using CFE bootloader have several
+ partitions without any on-flash partition table. On some devices their sizes
+ and/or meanings can also vary so fixed partitioning can't be used.
+
+ Discovering partitions on these devices is possible thanks to having a special
+ header and/or magic signature at the beginning of each of them. They are also
+ block aligned which is important for determinig a size.
+
+ Most of partitions use ASCII text based magic for determining a type. More
+ complex partitions (like TRX with its HDR0 magic) may include extra header
+ containing some details, including a length.
+
+ A list of supported partitions includes:
+ 1) Bootloader with Broadcom's CFE (Common Firmware Environment)
+ 2) NVRAM with configuration/calibration data
+ 3) Device manufacturer's data with some default values (e.g. SSIDs)
+ 4) TRX firmware container which can hold up to 4 subpartitions
+ 5) Backup TRX firmware used after failed upgrade
+
+ As mentioned earlier, role of some partitions may depend on extra
+ configuration. For example both: main firmware and backup firmware use the
+ same TRX format with the same header. To distinguish currently used firmware a
+ CFE's environment variable "bootpartition" is used.

+Most Broadcom BCM63XX SoC based devices follow the Broadcom reference layout for

+header found at beginning of the second erase block, containing the rootfs and

+Broadcom TRX Container Partition
+================================
+
+TRX is Broadcom's official firmware format for the BCM947xx boards. It's used by
+most of the vendors building devices based on Broadcom's BCM47xx SoCs and is
+supported by the CFE bootloader.
+
+Design of the TRX format is very minimalistic. Its header contains
+identification fields, CRC32 checksum and the locations of embedded partitions.
+Its purpose is to store a few partitions in a format that can be distributed as
+a standalone file and written in a flash memory.
+
+Container can hold up to 4 partitions. The first partition has to contain a
+device executable binary (e.g. a kernel) as it's what the CFE bootloader starts
+executing. Other partitions can be used for operating system purposes. This is
+useful for systems that keep kernel and rootfs separated.
+
+TRX doesn't enforce any strict partition boundaries or size limits. All
+partitions have to be less than the 4GiB max size limit.
+
+There are two existing/known TRX variants:
+1) v1 which contains 3 partitions
+2) v2 which contains 4 partitions
+
+There aren't separated compatible bindings for them as version can be trivialy
+detected by a software parsing TRX header.
+
+Required properties:
+- compatible : (required) must be "brcm,trx"
+
+Optional properties:
+
+- brcm,trx-magic: TRX magic, if it is different from the default magic
+ 0x30524448 as a u32.
+
+Example:
+
+flash@0 {
+ partitions {
+ compatible = "brcm,trx";
+ };
+};

+ It uses one single flash eraseblock in the flash to store an index of
+ all images in the flash.
+ This block size will vary depending on flash but is typically

+title: TP-Link SafeLoader partitions
+
+description: |
+ TP-Link home routers store various data on flash (e.g. bootloader,
+ flash layout, firmware, product info, configuration, calibration
+ data). That requires flash partitioning.
+
+ Flash space layout of TP-Link devices is stored on flash itself using
+ a custom ASCII-based format. That format was first found in TP-Link
+ devices with a custom SafeLoader bootloader. Later it was adapted to
+ CFE and U-Boot bootloaders.
+
+ Partitions specified in partitions table cover whole flash space. Some
+ contain static data that shouldn't get modified (device's MAC or WiFi
+ calibration data). Others are semi-static (like kernel). Finally some
+ partitions contain fully changeable content (like rootfs).
+
+ This binding describes partitioning method and defines offset of ASCII
+ based partitions table. That offset is picked at manufacturing process
+ and doesn't change.

+Freescale's NAND flash controller (NFC)
+
+This variant of the Freescale NAND flash controller (NFC) can be found on
+Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc".
+- reg: address range of the NFC.
+- interrupts: interrupt of the NFC.
+- #address-cells: shall be set to 1. Encode the nand CS.
+- #size-cells : shall be set to 0.
+- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
+- assigned-clock-rates: The NAND bus timing is derived from this clock
+ rate and should not exceed maximum timing for any NAND memory chip
+ in a board stuffing. Typical NAND memory timings derived from this
+ clock are found in the SoC hardware reference manual. Furthermore,
+ there might be restrictions on maximum rates when using hardware ECC.
+
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+ representing partitions.
+
+Required children nodes:
+Children nodes represent the available nand chips. Currently the driver can
+only handle one NAND chip.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc-cs".
+- nand-bus-width: see nand-controller.yaml
+- nand-ecc-mode: see nand-controller.yaml
+
+Required properties for hardware ECC:
+- nand-ecc-strength: supported strengths are 24 and 32 bit (see nand-controller.yaml)
+- nand-ecc-step-size: step size equals page size, currently only 2k pages are
+ supported
+- nand-on-flash-bbt: see nand-controller.yaml
+
+Example:
+
+ nfc: nand@400e0000 {
+ compatible = "fsl,vf610-nfc";
+ #address-cells = <1>;

+description: |
+ A multiplexer (or mux) controller will have one, or several, consumer devices
+ that uses the mux controller. Thus, a mux controller can possibly control
+ several parallel multiplexers. Presumably there will be at least one
+ multiplexer needed by each consumer, but a single mux controller can of course
+ control several multiplexers for a single consumer.
+
+ A mux controller provides a number of states to its consumers, and the state
+ space is a simple zero-based enumeration. I.e. 0-1 for a 2-way multiplexer,
+ 0-7 for an 8-way multiplexer, etc.
+
+
+ Mux controller nodes
+ --------------------
+
+ Mux controller nodes must specify the number of cells used for the
+ specifier using the '#mux-control-cells' or '#mux-state-cells' property.
+ The value of '#mux-state-cells' will always be one greater than the value
+ of '#mux-control-cells'.
+
+ Optionally, mux controller nodes can also specify the state the mux should
+ have when it is idle. The idle-state property is used for this. If the
+ idle-state is not present, the mux controller is typically left as is when
+ it is idle. For multiplexer chips that expose several mux controllers, the
+ idle-state property is an array with one idle state for each mux controller.
+
+ The special value (-1) may be used to indicate that the mux should be left
+ as is when it is idle. This is the default, but can still be useful for
+ mux controller chips with more than one mux controller, particularly when
+ there is a need to "step past" a mux controller and set some other idle
+ state for a mux controller with a higher index.
+
+ Some mux controllers have the ability to disconnect the input/output of the
+ multiplexer. Using this disconnected high-impedance state as the idle state
+ is indicated with idle state (-2).
+
+ These constants are available in
+
+ #include <dt-bindings/mux/mux.h>
+
+ as MUX_IDLE_AS_IS (-1) and MUX_IDLE_DISCONNECT (-2).
+
+ An example mux controller node look like this (the adg972a chip is a triple
+ 4-way multiplexer):
+
+ mux: mux-controller@50 {
+ compatible = "adi,adg792a";
+ reg = <0x50>;

+description: |
+ The ADIN1110 is a low power single port 10BASE-T1L MAC-
+ PHY designed for industrial Ethernet applications. It integrates
+ an Ethernet PHY core with a MAC and all the associated analog
+ circuitry, input and output clock buffering.
+
+ The ADIN2111 is a low power, low complexity, two-Ethernet ports
+ switch with integrated 10BASE-T1L PHYs and one serial peripheral
+ interface (SPI) port. The device is designed for industrial Ethernet
+ applications using low power constrained nodes and is compliant
+ with the IEEE 802.3cg-2019 Ethernet standard for long reach
+ 10 Mbps single pair Ethernet (SPE).
+
+ The device has a 4-wire SPI interface for communication
+ between the MAC and host processor.

+* AMD 10GbE driver (amd-xgbe)
+
+Required properties:
+- compatible: Should be "amd,xgbe-seattle-v1a"
+- reg: Address and length of the register sets for the device
+ - MAC registers
+ - PCS registers
+ - SerDes Rx/Tx registers
+ - SerDes integration registers (1/2)
+ - SerDes integration registers (2/2)
+- interrupts: Should contain the amd-xgbe interrupt(s). The first interrupt
+ listed is required and is the general device interrupt. If the optional
+ amd,per-channel-interrupt property is specified, then one additional
+ interrupt for each DMA channel supported by the device should be specified.
+ The last interrupt listed should be the PCS auto-negotiation interrupt.
+- clocks:
+ - DMA clock for the amd-xgbe device (used for calculating the
+ correct Rx interrupt watchdog timer value on a DMA channel
+ for coalescing)
+ - PTP clock for the amd-xgbe device
+- clock-names: Should be the names of the clocks
+ - "dma_clk" for the DMA clock
+ - "ptp_clk" for the PTP clock
+- phy-mode: See ethernet.txt file in the same directory
+
+Optional properties:
+- dma-coherent: Present if dma operations are coherent
+- amd,per-channel-interrupt: Indicates that Rx and Tx complete will generate
+ a unique interrupt for each DMA channel - this requires an additional
+ interrupt be configured for each DMA channel
+- amd,speed-set: Speed capabilities of the device
+ 0 - 1GbE and 10GbE (default)
+ 1 - 2.5GbE and 10GbE
+
+The MAC address will be determined using the optional properties defined in
+ethernet.txt.
+
+The following optional properties are represented by an array with each
+value corresponding to a particular speed. The first array value represents
+the setting for the 1GbE speed, the second value for the 2.5GbE speed and
+the third value for the 10GbE speed. All three values are required if the
+property is used.
+- amd,serdes-blwc: Baseline wandering correction enablement
+ 0 - Off
+ 1 - On
+- amd,serdes-cdr-rate: CDR rate speed selection
+- amd,serdes-pq-skew: PQ (data sampling) skew
+- amd,serdes-tx-amp: TX amplitude boost
+- amd,serdes-dfe-tap-config: DFE taps available to run
+- amd,serdes-dfe-tap-enable: DFE taps to enable

+* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
+
+Required properties:
+- compatible: Should be "snps,arc-emac"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the EMAC interrupts
+- max-speed: see ethernet.txt file in the same directory.
+- phy: see ethernet.txt file in the same directory.
+
+Optional properties:
+- phy-reset-gpios : Should specify the gpio for phy reset
+- phy-reset-duration : Reset duration in milliseconds. Should present
+ only if property "phy-reset-gpios" is available. Missing the property
+ will have the duration be 1 millisecond. Numbers greater than 1000 are
+ invalid and 1 millisecond will be used instead.
+
+Clock handling:
+The clock frequency is needed to calculate and set polling period of EMAC.
+It must be provided by one of:
+- clock-frequency: CPU frequency.
+- clocks: reference to the clock supplying the EMAC.
+
+Child nodes of the driver are the individual PHY devices connected to the
+MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
+
+Examples:
+
+ ethernet@c0fc2000 {
+ compatible = "snps,arc-emac";
+ reg = <0xc0fc2000 0x3c>;
+ interrupts = <6>;
+ mac-address = [ 00 11 22 33 44 55 ];
+
+ clock-frequency = <80000000>;
+ /* or */
+ clocks = <&emac_clock>;
+
+ max-speed = <100>;
+ phy = <&phy0>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+ phy0: ethernet-phy@0 {
+ reg = <1>;
+ };

+The Broadcom BCM87XX devices are a family of 10G Ethernet PHYs. They
+have these bindings in addition to the standard PHY bindings.
+
+Compatible: Should contain "broadcom,bcm8706" or "broadcom,bcm8727" and
+ "ethernet-phy-ieee802.3-c45"
+
+Optional Properties:
+
+- broadcom,c45-reg-init : one of more sets of 4 cells. The first cell
+ is the MDIO Manageable Device (MMD) address, the second a register
+ address within the MMD, the third cell contains a mask to be ANDed

+Generic Bluetooth controller over USB (btusb driver)
+---------------------------------------------------
+
+Required properties:
+
+ - compatible : should comply with the format "usbVID,PID" specified in
+ Documentation/devicetree/bindings/usb/usb-device.yaml
+ At the time of writing, the only OF supported devices
+ (more may be added later) are:
+
+ "usb1286,204e" (Marvell 8997)
+ "usbcf3,e300" (Qualcomm QCA6174A)
+ "usb4ca,301a" (Qualcomm QCA6174A (Lite-On))
+
+
+Also, vendors that use btusb may have device additional properties, e.g:
+Documentation/devicetree/bindings/net/marvell-bt-8xxx.txt
+
+Optional properties:
+
+ - interrupt-names: (see below)
+ - interrupts : The interrupt specified by the name "wakeup" is the interrupt
+ that shall be used for out-of-band wake-on-bt. Driver will
+ request this interrupt for wakeup. During system suspend, the
+ irq will be enabled so that the bluetooth chip can wakeup host
+ platform out of band. During system resume, the irq will be
+ disabled to make sure unnecessary interrupt is not received.
+
+Example:
+
+Following example uses irq pin number 3 of gpio0 for out of band wake-on-bt:
+
+&usb_host1_ehci {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ mvl_bt1: bt@1 {
+ compatible = "usb1286,204e";

+ Message RAM configuration data.
+ Multiple M_CAN instances can share the same Message RAM
+ and each element(e.g Rx FIFO or Tx Buffer and etc) number
+ in Message RAM is also configurable, so this property is
+ telling driver how the shared or private Message RAM are
+ used by this M_CAN controller.
+
+ The format should be as follows:
+ <offset sidf_elems xidf_elems rxf0_elems rxf1_elems rxb_elems txe_elems txb_elems>
+ The 'offset' is an address offset of the Message RAM where
+ the following elements start from. This is usually set to
+ 0x0 if you're using a private Message RAM. The remain cells
+ are used to specify how many elements are used for each FIFO/Buffer.
+
+ M_CAN includes the following elements according to user manual:
+ 11-bit Filter 0-128 elements / 0-128 words
+ 29-bit Filter 0-64 elements / 0-128 words
+ Rx FIFO 0 0-64 elements / 0-1152 words
+ Rx FIFO 1 0-64 elements / 0-1152 words
+ Rx Buffers 0-64 elements / 0-1152 words

+Memory mapped Bosch CC770 and Intel AN82527 CAN controller
+
+Note: The CC770 is a CAN controller from Bosch, which is 100%
+compatible with the old AN82527 from Intel, but with "bugs" being fixed.
+
+Required properties:
+
+- compatible : should be "bosch,cc770" for the CC770 and "intc,82527"
+ for the AN82527.
+
+- reg : should specify the chip select, address offset and size required
+ to map the registers of the controller. The size is usually 0x80.
+
+- interrupts : property with a value describing the interrupt source
+ (number and sensitivity) required for the controller.
+
+Optional properties:
+
+- bosch,external-clock-frequency : frequency of the external oscillator
+ clock in Hz. Note that the internal clock frequency used by the
+ controller is half of that value. If not specified, a default
+ value of 16000000 (16 MHz) is used.
+
+- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin.
+ If not specified or if the specified value is 0, the CLKOUT pin
+ will be disabled.
+
+- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified,
+ a reasonable value will be calculated.
+
+- bosch,disconnect-rx0-input : see data sheet.
+
+- bosch,disconnect-rx1-input : see data sheet.
+
+- bosch,disconnect-tx1-output : see data sheet.
+
+- bosch,polarity-dominant : see data sheet.
+
+- bosch,divide-memory-clock : see data sheet.
+
+- bosch,iso-low-speed-mux : see data sheet.
+
+For further information, please have a look to the CC770 or AN82527.
+
+Examples:
+
+can@3,100 {
+ compatible = "bosch,cc770";
+ reg = <3 0x100 0x80>;
+ interrupts = <2 0>;
+ interrupt-parent = <&mpic>;
+ bosch,external-clock-frequency = <16000000>;

+Aeroflex Gaisler GRCAN and GRHCAN CAN controllers.
+
+The GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
+library.
+
+Note: These properties are built from the AMBA plug&play in a Leon SPARC system
+(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
+sparc.
+
+Required properties:
+
+- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
+
+- reg : Address and length of the register set for the device
+
+- freq : Frequency of the external oscillator clock in Hz (the frequency of
+ the amba bus in the ordinary case)
+
+- interrupts : Interrupt number for this device
+
+Optional properties:
+
+- systemid : If not present or if the value of the least significant 16 bits
+ of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
+ a bug workaround is activated.
+
+For further information look in the documentation for the GLIB IP core library:

+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source shall be used for the controller:
+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+ are: "ip" for ip bus clock
+ "ref" for reference clock (XTAL)
+ "ref" is default in case this property is not
+ present.
+
+fsl,mpc5121-mscan nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source and divider shall be used for the controller:
+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+ are: "ip" for ip bus clock
+ "ref" for reference clock
+ "sys" for system clock
+ If this property is not present, an optimal CAN
+ clock source and frequency based on the system
+ clock will be selected. If this is not possible,
+ the reference clock will be used.
+
+- fsl,mscan-clock-divider: for the reference and system clock, an additional
+ clock divider can be specified. By default, a
+ value of 1 is used.
+
+Note that the MPC5121 Rev. 1 processor is not supported.

+Cortina Phy Driver Device Tree Bindings
+---------------------------------------
+
+CORTINA is a registered trademark of Cortina Systems, Inc.
+
+The driver supports the Cortina Electronic Dispersion Compensation (EDC)
+devices, equipped with clock and data recovery (CDR) circuits. These
+devices make use of registers that are not compatible with Clause 45 or
+Clause 22, therefore they need to be described using the
+"ethernet-phy-id" compatible.
+
+Since the driver only implements polling mode support, interrupts info
+can be skipped.
+
+Example (CS4340 phy):
+ mdio {
+ cs4340_phy@10 {
+ compatible = "ethernet-phy-id13e5.1002";
+ reg = <0x10>;
+ };

+TI SoC Ethernet Switch Controller Device Tree Bindings
+------------------------------------------------------
+
+Required properties:
+- compatible : Should be one of the below:-
+ "ti,cpsw" for backward compatible
+ "ti,am335x-cpsw" for AM335x controllers
+ "ti,am4372-cpsw" for AM437x controllers
+ "ti,dra7-cpsw" for DRA7x controllers
+- reg : physical base address and size of the cpsw
+ registers map
+- interrupts : property with a value describing the interrupt
+ number
+- cpdma_channels : Specifies number of channels in CPDMA
+- ale_entries : Specifies No of entries ALE can hold
+- bd_ram_size : Specifies internal descriptor RAM size
+- mac_control : Specifies Default MAC control register content
+ for the specific platform
+- slaves : Specifies number for slaves
+- active_slave : Specifies the slave to use for time stamping,
+ ethtool and SIOCGMIIPHY
+- cpsw-phy-sel : Specifies the phandle to the CPSW phy mode selection
+ device. See also cpsw-phy-sel.txt for its binding.
+ Note that in legacy cases cpsw-phy-sel may be
+ a child device instead of a phandle
+ (DEPRECATED, use phys property instead).
+
+Optional properties:
+- ti,hwmods : Must be "cpgmac0"
+- dual_emac : Specifies Switch to act as Dual EMAC
+- syscon : Phandle to the system control device node, which is
+ the control module device of the am33x
+- mode-gpios : Should be added if one/multiple gpio lines are
+ required to be driven so that cpsw data lines
+ can be connected to the phy via selective mux.
+ For example in dra72x-evm, pcf gpio has to be
+ driven low so that cpsw slave 0 and phy data
+ lines are connected via mux.
+- cpts_clock_mult : Numerator to convert input clock ticks into nanoseconds
+- cpts_clock_shift : Denominator to convert input clock ticks into nanoseconds
+ Mult and shift will be calculated basing on CPTS
+ rftclk frequency if both cpts_clock_shift and
+ cpts_clock_mult properties are not provided.
+
+Slave Properties:
+Required properties:
+- phy-mode : See ethernet.txt file in the same directory
+- phys : phandle on phy-gmii-sel PHY (see phy/ti-phy-gmii-sel.txt)
+
+Optional properties:
+- dual_emac_res_vlan : Specifies VID to be used to segregate the ports
+- phy_id : Specifies slave phy id (deprecated, use phy-handle)
+- phy-handle : See ethernet.txt file in the same directory
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Slave sub-nodes:
+- fixed-link : See fixed-link.txt file in the same directory
+
+Note: Exactly one of phy_id, phy-handle, or fixed-link must be specified.
+
+Note: "ti,hwmods" field is used to fetch the base address and irq
+resources from TI, omap hwmod data base during device registration.
+Future plan is to migrate hwmod data base contents into device tree
+blob so that, all the required data will be used from device tree dts
+file.

+
+ - compatible: should be: "qca,ar9331-switch"
+ - reg: Address on the MII bus for the switch.
+ - resets : Must contain an entry for each entry in reset-names.
+ - reset-names : Must include the following entries: "switch"
+ - interrupt-parent: Phandle to the parent interrupt controller
+ - interrupts: IRQ line for the switch
+ - interrupt-controller: Indicates the switch is itself an interrupt
+ controller. This is used for the PHY interrupts.
+ - #interrupt-cells: must be 1

+- compatible: should be
+ - "smsc,lan9303-i2c" for I2C managed mode
+ or
+ - "smsc,lan9303-mdio" for mdio managed mode
+
+Optional properties:
+
+- reset-gpios: GPIO to be used to reset the whole device
+- reset-duration: reset duration in milliseconds, defaults to 200 ms
+
+Subnodes:
+
+The integrated switch subnode should be specified according to the binding
+described in dsa/dsa.txt. The CPU port of this switch is always port 0.
+
+Note: always use 'reg = <0/1/2>;' for the three DSA ports, even if the device is
+configured to use 1/2/3 instead. This hardware configuration will be
+auto-detected and mapped accordingly.

+Marvell DSA Switch Device Tree Bindings
+---------------------------------------
+
+WARNING: This binding is currently unstable. Do not program it into a

+
+If you need a stable binding, use the old dsa.txt binding.
+
+Marvell Switches are MDIO devices. The following properties should be
+placed as a child node of an mdio device.
+
+The properties described here are those specific to Marvell devices.
+Additional required and optional properties can be found in dsa.txt.
+
+The compatibility string is used only to find an identification register,
+which is at a different MDIO base address in different switch families.
+- "marvell,mv88e6085" : Switch has base address 0x10. Use with models:
+ 6085, 6095, 6097, 6123, 6131, 6141, 6161, 6165,
+ 6171, 6172, 6175, 6176, 6185, 6240, 6320, 6321,
+ 6341, 6350, 6351, 6352
+- "marvell,mv88e6190" : Switch has base address 0x00. Use with models:
+ 6190, 6190X, 6191, 6290, 6361, 6390, 6390X
+- "marvell,mv88e6250" : Switch has base address 0x08 or 0x18. Use with model:
+ 6220, 6250
+
+Required properties:

+ "marvell,mv88e6190" or "marvell,mv88e6250" as
+ indicated above
+- reg : Address on the MII bus for the switch.
+
+Optional properties:
+
+- reset-gpios : Should be a gpio specifier for a reset line
+- interrupts : Interrupt from the switch
+- interrupt-controller : Indicates the switch is itself an interrupt
+ controller. This is used for the PHY interrupts.
+#interrupt-cells = <2> : Controller uses two cells, number and flag
+- eeprom-length : Set to the length of an EEPROM connected to the
+ switch. Must be set if the switch can not detect
+ the presence and/or size of a connected EEPROM,
+ otherwise optional.
+- mdio : Container of PHY and devices on the switches MDIO
+ bus.
+- mdio? : Container of PHYs and devices on the external MDIO
+ bus. The node must contains a compatible string of
+ "marvell,mv88e6xxx-mdio-external"
+
+Example:
+
+ mdio {

+description: |
+ There are three versions of MT7530, standalone, in a multi-chip module and
+ built-into a SoC.
+
+ MT7530 is a part of the multi-chip module in MT7620AN, MT7620DA, MT7620DAN,
+ MT7620NN, MT7621AT, MT7621DAT, MT7621ST and MT7623AI SoCs.
+
+ The MT7988 SoC comes with a built-in switch similar to MT7531 as well as four
+ Gigabit Ethernet PHYs. The switch registers are directly mapped into the SoC's
+ memory map rather than using MDIO. The switch got an internally connected 10G
+ CPU port and 4 user ports connected to the built-in Gigabit Ethernet PHYs.
+
+ MT7530 in MT7620AN, MT7620DA, MT7620DAN and MT7620NN SoCs has got 10/100 PHYs
+ and the switch registers are directly mapped into SoC's memory map rather than
+ using MDIO. The DSA driver currently doesn't support MT7620 variants.
+
+ There is only the standalone version of MT7531.
+
+ Port 5 on MT7530 has got various ways of configuration:
+
+ - Port 5 can be used as a CPU port.
+
+ - PHY 0 or 4 of the switch can be muxed to gmac5 of the switch. Therefore,
+ the gmac of the SoC which is wired to port 5 can connect to the PHY.
+ This is usually used for connecting the wan port directly to the CPU to
+ achieve 2 Gbps routing in total.
+
+ The driver looks up the reg on the ethernet-phy node, which the phy-handle
+ property on the gmac node refers to, to mux the specified phy.
+
+ The driver requires the gmac of the SoC to have "mediatek,eth-mac" as the
+ compatible string and the reg must be 1. So, for now, only gmac1 of a
+ MediaTek SoC can benefit this. Banana Pi BPI-R2 suits this.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+
+ Check out example 5.
+
+ - For the multi-chip module MT7530, in case of an external phy wired to
+ gmac1 of the SoC, port 5 must not be enabled.
+
+ In case of muxing PHY 0 or 4, the external phy must not be enabled.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+
+ Check out example 6.
+
+ - Port 5 can be wired to an external phy. Port 5 becomes a DSA slave.
+
+ For the multi-chip module MT7530, the external phy must be wired TX to TX
+ to gmac1 of the SoC for this to work. Ubiquiti EdgeRouter X SFP is wired
+ this way.
+
+ For the multi-chip module MT7530, muxing PHY 0 or 4 won't work when the
+ external phy is connected TX to TX.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with gpio function.
+
+ Check out example 7.

+description: |
+ There are multiple switches which are either part of the Ocelot-1 family, or
+ derivatives of this architecture. These switches can be found embedded in
+ various SoCs and accessed using MMIO, or as discrete chips and accessed over
+ SPI or PCIe. The present DSA binding shall be used when the host controlling
+ them performs packet I/O primarily through an Ethernet port of the switch
+ (which is attached to an Ethernet port of the host), rather than through
+ Frame DMA or register-based I/O.
+
+ VSC9953 (Seville):
+
+ This is found in the NXP T1040, where it is a memory-mapped platform
+ device.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 8 and 9
+ - phy-mode = "sgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7
+ - phy-mode = "qsgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7
+ - phy-mode = "1000base-x": on ports 0, 1, 2, 3, 4, 5, 6, 7
+
+ VSC9959 (Felix):
+
+ This is found in the NXP LS1028A. It is a PCI device, part of the larger
+ enetc root complex. As a result, the ethernet-switch node is a sub-node of
+ the PCIe root complex node and its "reg" property conforms to the parent
+ node bindings, describing it as PF 5 of device 0, bus 0.
+
+ If any external switch port is enabled, the enetc PF2 (enetc_port2) should
+ be enabled as well. This is because the internal MDIO bus (exposed through
+ EA BAR 0) used to access the MAC PCS registers truly belongs to the enetc
+ port 2 and not to Felix.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 4 and 5
+ - phy-mode = "sgmii": on ports 0, 1, 2, 3
+ - phy-mode = "qsgmii": on ports 0, 1, 2, 3
+ - phy-mode = "usxgmii": on ports 0, 1, 2, 3
+ - phy-mode = "1000base-x": on ports 0, 1, 2, 3

+description:
+ If the QCA8K switch is connect to an SoC's external mdio-bus, each subnode
+ describing a port needs to have a valid phandle referencing the internal PHY
+ it is connected to. This is because there is no N:N mapping of port and PHY
+ ID. To declare the internal mdio-bus configuration, declare an MDIO node in
+ the switch node and declare the phandle for the port, referencing the internal
+ PHY it is connected to. In this config, an internal mdio-bus is registered and
+ the MDIO master is used for communication. Mixed external and internal
+ mdio-bus configurations are not supported by the hardware.
+ Each phy has at most 3 LEDs connected and can be declared
+ using the standard LEDs structure.

+description:
+ Realtek advertises these chips as fast/gigabit switches or unmanaged
+ switches. They can be controlled using different interfaces, like SMI,
+ MDIO or SPI.
+
+ The SMI "Simple Management Interface" is a two-wire protocol using
+ bit-banged GPIO that while it reuses the MDIO lines MCK and MDIO does
+ not use the MDIO protocol. This binding defines how to specify the
+ SMI-based Realtek devices. The realtek-smi driver is a platform driver
+ and it must be inserted inside a platform node.
+
+ The MDIO-connected switches use MDIO protocol to access their registers.
+ The realtek-mdio driver is an MDIO driver and it must be inserted inside
+ an MDIO node.
+
+ The compatible string is only used to identify which (silicon) family the
+ switch belongs to. Roughly speaking, a family is any set of Realtek switches
+ whose chip identification register(s) have a common location and semantics.
+ The different models in a given family can be automatically disambiguated by
+ parsing the chip identification register(s) according to the given family,
+ avoiding the need for a unique compatible string for each model.

+Vitesse VSC73xx Switches
+========================
+
+This defines device tree bindings for the Vitesse VSC73xx switch chips.
+The Vitesse company has been acquired by Microsemi and Microsemi has
+been acquired Microchip but retains this vendor branding.
+
+The currently supported switch chips are:
+Vitesse VSC7385 SparX-G5 5+1-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch
+
+This switch could have two different management interface.
+
+If SPI interface is used, the device tree node is an SPI device so it must
+reside inside a SPI bus device tree node, see spi/spi-bus.txt
+
+When the chip is connected to a parallel memory bus and work in memory-mapped
+I/O mode, a platform device is used to represent the vsc73xx. In this case it
+must reside inside a platform bus device tree node.
+
+Required properties:
+
+- compatible: must be exactly one of:
+ "vitesse,vsc7385"
+ "vitesse,vsc7388"
+ "vitesse,vsc7395"
+ "vitesse,vsc7398"
+- gpio-controller: indicates that this switch is also a GPIO controller,
+ see gpio/gpio.txt
+- #gpio-cells: this must be set to <2> and indicates that we are a twocell
+ GPIO controller, see gpio/gpio.txt
+
+Optional properties:
+
+- reset-gpios: a handle to a GPIO line that can issue reset of the chip.
+ It should be tagged as active low.
+
+Required subnodes:
+
+See net/dsa/dsa.txt for a list of additional required and optional properties
+and subnodes of DSA switches.
+
+Examples:
+
+SPI:
+switch@0 {
+ compatible = "vitesse,vsc7395";
+ reg = <0>;
+ /* Specified for 2.5 MHz or below */
+ spi-max-frequency = <2500000>;

+ };
+ port@2 {
+ reg = <2>;
+ label = "lan3";
+ };
+ port@3 {

+* ENETC ethernet device tree bindings
+
+Depending on board design and ENETC port type (internal or
+external) there are two supported link modes specified by
+below device tree bindings.
+
+Required properties:
+
+- reg : Specifies PCIe Device Number and Function
+ Number of the ENETC endpoint device, according
+ to parent node bindings.
+- compatible : Should be "fsl,enetc".
+
+1. The ENETC external port is connected to a MDIO configurable phy
+
+1.1. Using the local ENETC Port MDIO interface
+
+In this case, the ENETC node should include a "mdio" sub-node
+that in turn should contain the "ethernet-phy" node describing the
+external phy. Below properties are required, their bindings
+already defined in Documentation/devicetree/bindings/net/ethernet.txt or
+Documentation/devicetree/bindings/net/phy.txt.
+
+Required:
+
+- phy-handle : Phandle to a PHY on the MDIO bus.
+ Defined in ethernet.txt.
+
+- phy-connection-type : Defined in ethernet.txt.
+
+- mdio : "mdio" node, defined in mdio.txt.
+
+- ethernet-phy : "ethernet-phy" node, defined in phy.txt.
+
+Example:
+
+ ethernet@0,0 {
+ compatible = "fsl,enetc";
+ reg = <0x000000 0 0 0 0>;
+ phy-handle = <&sgmii_phy0>;
+ phy-connection-type = "sgmii";
+
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ sgmii_phy0: ethernet-phy@2 {
+ reg = <0x2>;
+ };
+ };
+ };
+
+1.2. Using the central MDIO PCIe endpoint device
+
+In this case, the mdio node should be defined as another PCIe
+endpoint node, at the same level with the ENETC port nodes.
+
+Required properties:
+
+- reg : Specifies PCIe Device Number and Function
+ Number of the ENETC endpoint device, according
+ to parent node bindings.
+- compatible : Should be "fsl,enetc-mdio".
+
+The remaining required mdio bus properties are standard, their bindings
+already defined in Documentation/devicetree/bindings/net/mdio.txt.
+
+Example:
+
+ ethernet@0,0 {
+ compatible = "fsl,enetc";
+ reg = <0x000000 0 0 0 0>;
+ phy-handle = <&sgmii_phy0>;
+ phy-connection-type = "sgmii";
+ };
+
+ mdio@0,3 {
+ compatible = "fsl,enetc-mdio";
+ reg = <0x000300 0 0 0 0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ sgmii_phy0: ethernet-phy@2 {
+ reg = <0x2>;
+ };
+ };
+
+2. The ENETC port is an internal port or has a fixed-link external
+connection
+
+In this case, the ENETC port node defines a fixed link connection,
+as specified by Documentation/devicetree/bindings/net/fixed-link.txt.
+
+Required:
+
+- fixed-link : "fixed-link" node, defined in "fixed-link.txt".
+
+Example:
+ ethernet@0,2 {
+ compatible = "fsl,enetc";
+ reg = <0x000200 0 0 0 0>;
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ };
+
+* Integrated Endpoint Register Block bindings
+
+Optionally, the fsl_enetc driver can probe on the Integrated Endpoint Register
+Block, which preconfigures the FIFO limits for the ENETC ports. This is a node
+with the following properties:
+
+- reg : Specifies the address in the SoC memory space.
+- compatible : Must be "fsl,ls1028a-enetc-ierb".
+
+Example:
+ ierb@1f0800000 {
+ compatible = "fsl,ls1028a-enetc-ierb";
+ reg = <0x01 0xf0800000 0x0 0x10000>;
+ };

+* MDIO IO device
+
+The MDIO is a bus to which the PHY devices are connected. For each
+device that exists on this bus, a child node should be created. See
+the definition of the PHY node in booting-without-of.txt for an example
+of how to define a PHY.
+
+Required properties:
+ - reg : Offset and length of the register set for the device, and optionally
+ the offset and length of the TBIPA register (TBI PHY address
+ register). If TBIPA register is not specified, the driver will
+ attempt to infer it from the register set specified (your mileage may
+ vary).
+ - compatible : Should define the compatible device type for the
+ mdio. Currently supported strings/devices are:
+ - "fsl,gianfar-tbi"
+ - "fsl,gianfar-mdio"
+ - "fsl,etsec2-tbi"
+ - "fsl,etsec2-mdio"
+ - "fsl,ucc-mdio"
+ - "fsl,fman-mdio"
+ When device_type is "mdio", the following strings are also considered:
+ - "gianfar"
+ - "ucc_geth_phy"
+
+Example:
+
+ mdio@24520 {
+ reg = <24520 20>;
+ compatible = "fsl,gianfar-mdio";
+
+ ethernet-phy@0 {
+ ......
+ };
+ };
+
+* TBI Internal MDIO bus
+
+As of this writing, every tsec is associated with an internal TBI PHY.
+This PHY is accessed through the local MDIO bus. These buses are defined
+similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi".
+The TBI PHYs underneath them are similar to normal PHYs, but the reg property
+is considered instructive, rather than descriptive. The reg property should
+be chosen so it doesn't interfere with other PHYs on the bus.
+
+* Gianfar-compatible ethernet nodes
+
+Properties:
+
+ - device_type : Should be "network"
+ - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC"
+ - compatible : Should be "gianfar"
+ - reg : Offset and length of the register set for the device
+ - interrupts : For FEC devices, the first interrupt is the device's
+ interrupt. For TSEC and eTSEC devices, the first interrupt is
+ transmit, the second is receive, and the third is error.
+ - phy-handle : See ethernet.txt file in the same directory.
+ - fixed-link : See fixed-link.txt in the same directory.
+ - phy-connection-type : See ethernet.txt file in the same directory.
+ This property is only really needed if the connection is of type
+ "rgmii-id", as all other connection types are detected by hardware.
+ - fsl,magic-packet : If present, indicates that the hardware supports
+ waking up via magic packet.
+ - fsl,wake-on-filer : If present, indicates that the hardware supports
+ waking up by Filer General Purpose Interrupt (FGPI) asserted on the
+ Rx int line. This is an advanced power management capability allowing
+ certain packet types (user) defined by filer rules to wake up the system.
+ - bd-stash : If present, indicates that the hardware supports stashing
+ buffer descriptors in the L2.
+ - rx-stash-len : Denotes the number of bytes of a received buffer to stash
+ in the L2.
+ - rx-stash-idx : Denotes the index of the first byte from the received
+ buffer to stash in the L2.
+
+Example:
+ ethernet@24000 {
+ device_type = "network";
+ model = "TSEC";
+ compatible = "gianfar";
+ reg = <0x24000 0x1000>;
+ local-mac-address = [ 00 E0 0C 00 73 00 ];
+ interrupts = <29 2 30 2 34 2>;
+ interrupt-parent = <&mpic>;
+ phy-handle = <&phy0>
+ };

+ 4xx/Axon EMAC ethernet nodes
+
+ The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+ the Axon bridge. To operate this needs to interact with a this
+ special McMAL DMA controller, and sometimes an RGMII or ZMII
+ interface. In addition to the nodes and properties described
+ below, the node for the OPB bus on which the EMAC sits must have a
+ correct clock-frequency property.
+
+ i) The EMAC node itself
+
+ Required properties:
+ - device_type : "network"
+
+ - compatible : compatible list, contains 2 entries, first is
+ "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
+ 405gp, Axon) and second is either "ibm,emac" or
+ "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
+ "ibm,emac4"
+ - interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
+ - reg : <registers mapping>
+ - local-mac-address : 6 bytes, MAC address
+ - mal-device : phandle of the associated McMAL node
+ - mal-tx-channel : 1 cell, index of the tx channel on McMAL associated
+ with this EMAC
+ - mal-rx-channel : 1 cell, index of the rx channel on McMAL associated
+ with this EMAC
+ - cell-index : 1 cell, hardware index of the EMAC cell on a given
+ ASIC (typically 0x0 and 0x1 for EMAC0 and EMAC1 on
+ each Axon chip)
+ - max-frame-size : 1 cell, maximum frame size supported in bytes
+ - rx-fifo-size : 1 cell, Rx fifo size in bytes for 10 and 100 Mb/sec
+ operations.
+ For Axon, 2048
+ - tx-fifo-size : 1 cell, Tx fifo size in bytes for 10 and 100 Mb/sec
+ operations.
+ For Axon, 2048.
+ - fifo-entry-size : 1 cell, size of a fifo entry (used to calculate
+ thresholds).
+ For Axon, 0x00000010
+ - mal-burst-size : 1 cell, MAL burst size (used to calculate thresholds)
+ in bytes.
+ For Axon, 0x00000100 (I think ...)
+ - phy-mode : string, mode of operations of the PHY interface.
+ Supported values are: "mii", "rmii", "smii", "rgmii",
+ "tbi", "gmii", rtbi", "sgmii".
+ For Axon on CAB, it is "rgmii"
+ - mdio-device : 1 cell, required iff using shared MDIO registers
+ (440EP). phandle of the EMAC to use to drive the
+ MDIO lines for the PHY used by this EMAC.
+ - zmii-device : 1 cell, required iff connected to a ZMII. phandle of
+ the ZMII device node
+ - zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
+ channel or 0xffffffff if ZMII is only used for MDIO.
+ - rgmii-device : 1 cell, required iff connected to an RGMII. phandle
+ of the RGMII device node.
+ For Axon: phandle of plb5/plb4/opb/rgmii
+ - rgmii-channel : 1 cell, required iff connected to an RGMII. Which
+ RGMII channel is used by this EMAC.
+ Fox Axon: present, whatever value is appropriate for each
+ EMAC, that is the content of the current (bogus) "phy-port"
+ property.
+
+ Optional properties:
+ - phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
+ a search is performed.
+ - phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
+ for, used if phy-address is absent. bit 0x00000001 is
+ MDIO address 0.
+ For Axon it can be absent, though my current driver
+ doesn't handle phy-address yet so for now, keep
+ 0x00ffffff in it.
+ - phy-handle : Used to describe configurations where a external PHY
+ is used. Please refer to:
+ Documentation/devicetree/bindings/net/ethernet.txt
+ - rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
+ operations (if absent the value is the same as
+ rx-fifo-size). For Axon, either absent or 2048.
+ - tx-fifo-size-gige : 1 cell, Tx fifo size in bytes for 1000 Mb/sec
+ operations (if absent the value is the same as
+ tx-fifo-size). For Axon, either absent or 2048.
+ - tah-device : 1 cell, optional. If connected to a TAH engine for
+ offload, phandle of the TAH device node.
+ - tah-channel : 1 cell, optional. If appropriate, channel used on the
+ TAH engine.
+ - fixed-link : Fixed-link subnode describing a link to a non-MDIO
+ managed entity. See
+ Documentation/devicetree/bindings/net/fixed-link.txt
+ for details.
+ - mdio subnode : When the EMAC has a phy connected to its local
+ mdio, which us supported by the kernel's network
+ PHY library in drivers/net/phy, there must be device
+ tree subnode with the following required properties:
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+
+ For PHY definitions: Please refer to
+ Documentation/devicetree/bindings/net/phy.txt and

+This document describes the device tree bindings associated with the
+keystone network coprocessor(NetCP) driver support.
+
+The network coprocessor (NetCP) is a hardware accelerator that processes
+Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet
+switch sub-module to send and receive packets. NetCP also includes a packet
+accelerator (PA) module to perform packet classification operations such as
+header matching, and packet modification operations such as checksum
+generation. NetCP can also optionally include a Security Accelerator (SA)
+capable of performing IPSec operations on ingress/egress packets.
+
+Keystone II SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which
+includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
+per Ethernet port.
+
+Keystone NetCP driver has a plug-in module architecture where each of the NetCP
+sub-modules exist as a loadable kernel module which plug in to the netcp core.
+These sub-modules are represented as "netcp-devices" in the dts bindings. It is
+mandatory to have the ethernet switch sub-module for the ethernet interface to
+be operational. Any other sub-module like the PA is optional.
+
+NetCP Ethernet SubSystem Layout:
+
+-----------------------------
+ NetCP subsystem(10G or 1G)
+-----------------------------
+ |
+ |-> NetCP Devices -> |
+ | |-> GBE/XGBE Switch
+ | |
+ | |-> Packet Accelerator
+ | |
+ | |-> Security Accelerator

+ |
+ |
+ |-> NetCP Interfaces -> |
+ |-> Ethernet Port 0
+ |
+ |-> Ethernet Port 1
+ |
+ |-> Ethernet Port 2
+ |
+ |-> Ethernet Port 3
+
+
+NetCP subsystem properties:
+Required properties:
+- compatible: Should be "ti,netcp-1.0"
+- clocks: phandle to the reference clocks for the subsystem.
+- dma-id: Navigator packet dma instance id.
+- ranges: address range of NetCP (includes, Ethernet SS, PA and SA)
+
+Optional properties:
+- reg: register location and the size for the following register
+ regions in the specified order.
+ - Efuse MAC address register
+- dma-coherent: Present if dma operations are coherent
+- big-endian: Keystone devices can be operated in a mode where the DSP is in
+ the big endian mode. In such cases enable this option. This
+ option should also be enabled if the ARM is operated in
+ big endian mode with the DSP in little endian.
+
+NetCP device properties: Device specification for NetCP sub-modules.
+1Gb/10Gb (gbe/xgbe) ethernet switch sub-module specifications.
+Required properties:
+- label: Must be "netcp-gbe" for 1Gb & "netcp-xgbe" for 10Gb.
+- compatible: Must be one of below:-
+ "ti,netcp-gbe" for 1GbE on NetCP 1.4
+ "ti,netcp-gbe-5" for 1GbE N NetCP 1.5 (N=5)
+ "ti,netcp-gbe-9" for 1GbE N NetCP 1.5 (N=9)
+ "ti,netcp-gbe-2" for 1GbE N NetCP 1.5 (N=2)
+ "ti,netcp-xgbe" for 10 GbE
+
+- reg: register location and the size for the following register
+ regions in the specified order.
+ - switch subsystem registers
+ - sgmii port3/4 module registers (only for NetCP 1.4)
+ - switch module registers
+ - serdes registers (only for 10G)
+
+ NetCP 1.4 ethss, here is the order
+ index #0 - switch subsystem registers
+ index #1 - sgmii port3/4 module registers
+ index #2 - switch module registers
+
+ NetCP 1.5 ethss 9 port, 5 port and 2 port
+ index #0 - switch subsystem registers
+ index #1 - switch module registers
+ index #2 - serdes registers
+
+- tx-channel: the navigator packet dma channel name for tx.
+- tx-queue: the navigator queue number associated with the tx dma channel.
+- interfaces: specification for each of the switch port to be registered as a
+ network interface in the stack.
+-- slave-port: Switch port number, 0 based numbering.
+-- link-interface: type of link interface, supported options are
+ - mac<->mac auto negotiate mode: 0
+ - mac<->phy mode: 1
+ - mac<->mac forced mode: 2
+ - mac<->fiber mode: 3
+ - mac<->phy mode with no mdio: 4
+ - 10Gb mac<->phy mode : 10
+ - 10Gb mac<->mac forced mode : 11
+----phy-handle: phandle to PHY device
+
+- cpts: sub-node time synchronization (CPTS) submodule configuration
+-- clocks: CPTS reference clock. Should point on cpts-refclk-mux clock.
+-- clock-names: should be "cpts"
+-- cpts-refclk-mux: multiplexer clock definition sub-node for CPTS reference (RFTCLK) clock
+--- #clock-cells: should be 0
+--- clocks: list of CPTS reference (RFTCLK) clock's parents as defined in Data manual
+--- ti,mux-tbl: array of multiplexer indexes as defined in Data manual
+--- assigned-clocks: should point on cpts-refclk-mux clock
+--- assigned-clock-parents: should point on required RFTCLK clock parent to be selected
+-- cpts_clock_mult: (optional) Numerator to convert input clock ticks
+ into nanoseconds
+-- cpts_clock_shift: (optional) Denominator to convert input clock ticks into
+ nanoseconds.
+ Mult and shift will be calculated basing on CPTS
+ rftclk frequency if both cpts_clock_shift and
+ cpts_clock_mult properties are not provided.
+
+Optional properties:
+- enable-ale: NetCP driver keeps the address learning feature in the ethernet
+ switch module disabled. This attribute is to enable the address
+ learning.
+- secondary-slave-ports: specification for each of the switch port not be
+ registered as a network interface. NetCP driver
+ will only initialize these ports and attach PHY
+ driver to them if needed.
+
+NetCP interface properties: Interface specification for NetCP sub-modules.
+Required properties:
+- rx-channel: the navigator packet dma channel name for rx.
+- rx-queue: the navigator queue number associated with rx dma channel.
+- rx-pool: specifies the number of descriptors to be used & the region-id
+ for creating the rx descriptor pool.
+- tx-pool: specifies the number of descriptors to be used & the region-id
+ for creating the tx descriptor pool.
+- rx-queue-depth: number of descriptors in each of the free descriptor
+ queue (FDQ) for the pktdma Rx flow. There can be at
+ present a maximum of 4 queues per Rx flow.
+- rx-buffer-size: the buffer size for each of the Rx flow FDQ.
+- tx-completion-queue: the navigator queue number where the descriptors are
+ recycled after Tx DMA completion.
+
+Optional properties:
+- efuse-mac: If this is 1, then the MAC address for the interface is
+ obtained from the device efuse mac address register.
+ If this is 2, the two DWORDs occupied by the MAC address
+ are swapped. The netcp driver will swap the two DWORDs
+ back to the proper order when this property is set to 2
+ when it obtains the mac address from efuse.
+- "netcp-device label": phandle to the device specification for each of NetCP
+ sub-module attached to this interface.
+
+The MAC address will be determined using the optional properties defined in
+ethernet.txt and only if efuse-mac is set to 0. If all of the optional MAC
+address properties are not present, then the driver will use a random MAC
+address.
+
+Example binding:

+ This controller is mounted on development boards for Marvell's Link Street
+ family of Ethernet switches. It allows you to configure the switch's registers
+ using the standard MDIO interface.
+
+ Since the device is connected over USB, there is no strict requirement of
+ having a device tree representation of the device. But in order to use it with
+ the mv88e6xxx driver, you need a device tree node in which to place the switch
+ definition.

+Marvell 8897/8997 (sd8897/sd8997) bluetooth devices (SDIO or USB based)
+------
+The 8997 devices supports multiple interfaces. When used on SDIO interfaces,
+the btmrvl driver is used and when used on USB interface, the btusb driver is
+used.
+
+Required properties:
+
+ - compatible : should be one of the following:
+ * "marvell,sd8897-bt" (for SDIO)
+ * "marvell,sd8997-bt" (for SDIO)
+ * "usb1286,204e" (for USB)
+
+Optional properties:
+
+ - marvell,cal-data: Calibration data downloaded to the device during
+ initialization. This is an array of 28 values(u8).
+ This is only applicable to SDIO devices.
+
+ - marvell,wakeup-pin: It represents wakeup pin number of the bluetooth chip.
+ firmware will use the pin to wakeup host system (u16).
+ - marvell,wakeup-gap-ms: wakeup gap represents wakeup latency of the host
+ platform. The value will be configured to firmware. This
+ is needed to work chip's sleep feature as expected (u16).
+ - interrupt-names: Used only for USB based devices (See below)
+ - interrupts : specifies the interrupt pin number to the cpu. For SDIO, the
+ driver will use the first interrupt specified in the interrupt
+ array. For USB based devices, the driver will use the interrupt
+ named "wakeup" from the interrupt-names and interrupt arrays.
+ The driver will request an irq based on this interrupt number.
+ During system suspend, the irq will be enabled so that the
+ bluetooth chip can wakeup host platform under certain
+ conditions. During system resume, the irq will be disabled
+ to make sure unnecessary interrupt is not received.
+
+Example:
+
+IRQ pin 119 is used as system wakeup source interrupt.
+wakeup pin 13 and gap 100ms are configured so that firmware can wakeup host
+using this device side pin and wakeup latency.
+
+Example for SDIO device follows (calibration data is also available in
+below example).

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - compatible: shall be one of "marvell,orion-eth-port",
+ "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: See ethernet.txt file in the same directory.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: See ethernet.txt file in the same directory.
+ - phy-mode: See ethernet.txt file in the same directory.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.

+description: |
+ An mctp-i2c-controller defines a local MCTP endpoint on an I2C controller.
+ MCTP I2C is specified by DMTF DSP0237.
+
+ An mctp-i2c-controller must be attached to an I2C adapter which supports
+ slave functionality. I2C busses (either directly or as subordinate mux
+ busses) are attached to the mctp-i2c-controller with a 'mctp-controller'
+ property on each used bus. Each mctp-controller I2C bus will be presented
+ to the host system as a separate MCTP I2C instance.

+MediaTek SoC built-in Bluetooth Devices
+==================================
+
+This device is a serial attached device to BTIF device and thus it must be a
+child node of the serial node with BTIF. The dt-bindings details for BTIF
+device can be known via Documentation/devicetree/bindings/serial/8250.yaml.
+
+Required properties:
+
+- compatible: Must be
+ "mediatek,mt7622-bluetooth": for MT7622 SoC
+- clocks: Should be the clock specifiers corresponding to the entry in
+ clock-names property.
+- clock-names: Should contain "ref" entries.
+- power-domains: Phandle to the power domain that the device is part of
+
+Example:
+
+ btif: serial@1100c000 {
+ compatible = "mediatek,mt7622-btif",
+ "mediatek,mtk-btif";
+ reg = <0 0x1100c000 0 0x1000>;
+ interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&pericfg CLK_PERI_BTIF_PD>;
+ clock-names = "main";
+ reg-shift = <2>;
+ reg-io-width = <4>;
+
+ bluetooth {
+ compatible = "mediatek,mt7622-bluetooth";
+ power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
+ clocks = <&clk25m>;
+ clock-names = "ref";
+ };
+ };
+
+MediaTek UART based Bluetooth Devices
+==================================
+
+This device is a serial attached device to UART device and thus it must be a
+child node of the serial node with UART.
+
+Please refer to the following documents for generic properties:
+
+ Documentation/devicetree/bindings/serial/serial.yaml
+
+Required properties:
+
+- compatible: Must be
+ "mediatek,mt7663u-bluetooth": for MT7663U device
+ "mediatek,mt7668u-bluetooth": for MT7668U device
+- vcc-supply: Main voltage regulator
+
+If the pin controller on the platform can support both pinmux and GPIO
+control such as the most of MediaTek platform. Please use below properties.
+
+- pinctrl-names: Should be "default", "runtime"
+- pinctrl-0: Should contain UART RXD low when the device is powered up to
+ enter proper bootstrap mode.
+- pinctrl-1: Should contain UART mode pin ctrl
+
+Else, the pin controller on the platform only can support pinmux control and
+the GPIO control still has to rely on the dedicated GPIO controller such as
+a legacy MediaTek SoC, MT7621. Please use the below properties.
+
+- boot-gpios: GPIO same to the pin as UART RXD and used to keep LOW when
+ the device is powered up to enter proper bootstrap mode when
+- pinctrl-names: Should be "default"
+- pinctrl-0: Should contain UART mode pin ctrl
+
+Optional properties:
+
+- reset-gpios: GPIO used to reset the device whose initial state keeps low,
+ if the GPIO is missing, then board-level design should be
+ guaranteed.
+- clocks: Should be the clock specifiers corresponding to the entry in
+ clock-names property. If the clock is missing, then board-level
+ design should be guaranteed.
+- clock-names: Should contain "osc" entry for the external oscillator.
+- current-speed: Current baud rate of the device whose defaults to 921600
+
+Example:
+
+ uart1_pins_boot: uart1-default {
+ pins-dat {
+ pinmux = <MT7623_PIN_81_URXD1_FUNC_GPIO81>;
+ output-low;
+ };

+ pinmux = <MT7623_PIN_81_URXD1_FUNC_URXD1>,
+ <MT7623_PIN_82_UTXD1_FUNC_UTXD1>;
+ };
+ };

+Micrel KSZ9021/KSZ9031/KSZ9131 Gigabit Ethernet PHY
+
+Some boards require special tuning values, particularly when it comes
+to clock delays. You can specify clock delay values in the PHY OF
+device node. Deprecated, but still supported, these properties can
+also be added to an Ethernet OF device node.
+
+Note that these settings are applied after any phy-specific fixup from
+phy_fixup_list (see phy_init_hw() from drivers/net/phy/phy_device.c),
+and therefore may overwrite them.
+
+KSZ9021:
+
+ All skew control options are specified in picoseconds. The minimum
+ value is 0, the maximum value is 3000, and it can be specified in 200ps
+ steps, *but* these values are in not fact what you get because this chip's
+ skew values actually increase in 120ps steps, starting from -840ps. The
+ incorrect values came from an error in the original KSZ9021 datasheet
+ before it was corrected in revision 1.2 (Feb 2014), but it is too late to
+ change the driver now because of the many existing device trees that have
+ been created using values that go up in increments of 200.
+
+ The following table shows the actual skew delay you will get for each of the
+ possible devicetree values, and the number that will be programmed into the
+ corresponding pad skew register:
+
+ Device Tree Value Delay Pad Skew Register Value
+ -----------------------------------------------------
+ 0 -840ps 0000

+ - txd3-skew-ps : Skew control of TX data 3 pad
+
+KSZ9031:
+
+ All skew control options are specified in picoseconds. The minimum
+ value is 0, and the maximum is property-dependent. The increment
+ step is 60ps. The default value is the neutral setting, so setting
+ rxc-skew-ps=<0> actually results in -900 picoseconds adjustment.
+
+ The KSZ9031 hardware supports a range of skew values from negative to
+ positive, where the specific range is property dependent. All values
+ specified in the devicetree are offset by the minimum value so they
+ can be represented as positive integers in the devicetree since it's
+ difficult to represent a negative number in the devictree.
+
+ The following 5-bit values table apply to rxc-skew-ps and txc-skew-ps.

+
+ See the respective PHY datasheet for the mode values.
+
+ - micrel,rmii-reference-clock-select-25-mhz: RMII Reference Clock Select
+ bit selects 25 MHz mode
+
+ Setting the RMII Reference Clock Select bit enables 25 MHz rather
+ than 50 MHz clock mode.
+
+ Note that this option in only needed for certain PHY revisions with a
+ non-standard, inverted function of this configuration bit.
+ Specifically, a clock reference ("rmii-ref" below) is always needed to
+ actually select a mode.
+
+ - clocks, clock-names: contains clocks according to the common clock bindings.
+
+ supported clocks:
+ - KSZ8021, KSZ8031, KSZ8081, KSZ8091: "rmii-ref": The RMII reference
+ input clock. Used to determine the XI input clock.
+
+ - micrel,fiber-mode: If present the PHY is configured to operate in fiber mode
+
+ Some PHYs, such as the KSZ8041FTL variant, support fiber mode, enabled
+ by the FXEN boot strapping pin. It can't be determined from the PHY
+ registers whether the PHY is in fiber mode, so this boolean device tree
+ property can be used to describe it.
+
+ In fiber mode, auto-negotiation is disabled and the PHY can only work in
+ 100base-fx (full and half duplex) modes.
+
+ - coma-mode-gpios: If present the given gpio will be deasserted when the
+ PHY is probed.
+
+ Some PHYs have a COMA mode input pin which puts the PHY into
+ isolate and power-down mode. On some boards this input is connected
+ to a GPIO of the SoC.
+
+ Supported on the LAN8814.

+* Microchip ENC28J60
+
+This is a standalone 10 MBit ethernet controller with SPI interface.
+
+For each device connected to a SPI bus, define a child node within
+the SPI master node.
+
+Required properties:
+- compatible: Should be "microchip,enc28j60"
+- reg: Specify the SPI chip select the ENC28J60 is wired to
+- interrupts: Specify the interrupt index within the interrupt controller (referred
+ to above in interrupt-parent) and interrupt type. The ENC28J60 natively
+ generates falling edge interrupts, however, additional board logic
+ might invert the signal.
+- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
+- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
+ see also generic and your platform specific pinctrl binding
+ documentation.
+
+Optional properties:
+- spi-max-frequency: Maximum frequency of the SPI bus when accessing the ENC28J60.
+ According to the ENC28J80 datasheet, the chip allows a maximum of 20 MHz, however,
+ board designs may need to limit this value.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Example (for NXP i.MX28 with pin control stuff for GPIO irq):
+
+ ssp2: ssp@80014000 {
+ compatible = "fsl,imx28-spi";
+ pinctrl-names = "default";

+Microchip LAN78xx Gigabit Ethernet controller
+
+The LAN78XX devices are usually configured by programming their OTP or with
+an external EEPROM, but some platforms (e.g. Raspberry Pi 3 B+) have neither.
+The Device Tree properties, if present, override the OTP and EEPROM.
+
+Required properties:
+- compatible: Should be one of "usb424,7800", "usb424,7801" or "usb424,7850".
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Optional properties of the embedded PHY:
+- microchip,led-modes: a 0..4 element vector, with each element configuring
+ the operating mode of an LED. Omitted LEDs are turned off. Allowed values
+ are defined in "include/dt-bindings/net/microchip-lan78xx.h".
+
+Example:
+
+/* Based on the configuration for a Raspberry Pi 3 B+ */
+&usb {
+ usb-port@1 {
+ compatible = "usb424,2514";
+ reg = <1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ usb-port@1 {
+ compatible = "usb424,2514";
+ reg = <1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ethernet: ethernet@1 {
+ compatible = "usb424,7800";
+ reg = <1>;
+ local-mac-address = [ 00 11 22 33 44 55 ];
+
+ mdio {
+ #address-cells = <0x1>;
+ #size-cells = <0x0>;
+ eth_phy: ethernet-phy@1 {
+ reg = <1>;
+ microchip,led-modes = <
+ LAN78XX_LINK_1000_ACTIVITY

+description: |
+ The SparX-5 Enterprise Ethernet switch family provides a rich set of
+ Enterprise switching features such as advanced TCAM-based VLAN and
+ QoS processing enabling delivery of differentiated services, and
+ security through TCAM-based frame processing using versatile content
+ aware processor (VCAP).
+
+ IPv4/IPv6 Layer 3 (L3) unicast and multicast routing is supported
+ with up to 18K IPv4/9K IPv6 unicast LPM entries and up to 9K IPv4/3K
+ IPv6 (S,G) multicast groups.
+
+ L3 security features include source guard and reverse path
+ forwarding (uRPF) tasks. Additional L3 features include VRF-Lite and
+ IP tunnels (IP over GRE/IP).
+
+ The SparX-5 switch family targets managed Layer 2 and Layer 3
+ equipment in SMB, SME, and Enterprise where high port count
+ 1G/2.5G/5G/10G switching with 10G/25G aggregation links is required.

+
+Optional properties:
+- vsc8531,vddmac : The vddmac in mV. Allowed values is listed
+ in the first row of Table 1 (below).
+ This property is only used in combination
+ with the 'edge-slowdown' property.
+ Default value is 3300.
+- vsc8531,edge-slowdown : % the edge should be slowed down relative to
+ the fastest possible edge time.
+ Edge rate sets the drive strength of the MAC
+ interface output signals. Changing the
+ drive strength will affect the edge rate of
+ the output signal. The goal of this setting
+ is to help reduce electrical emission (EMI)
+ by being able to reprogram drive strength
+ and in effect slow down the edge rate if
+ desired.
+ To adjust the edge-slowdown, the 'vddmac'
+ must be specified. Table 1 lists the
+ supported edge-slowdown values for a given
+ 'vddmac'.
+ Default value is 0%.
+ Ref: Table:1 - Edge rate change (below).
+- vsc8531,led-[N]-mode : LED mode. Specify how the LED[N] should behave.
+ N depends on the number of LEDs supported by a
+ PHY.
+ Allowed values are defined in
+ "include/dt-bindings/net/mscc-phy-vsc8531.h".
+ Default values are VSC8531_LINK_1000_ACTIVITY (1),
+ VSC8531_LINK_100_ACTIVITY (2),
+ VSC8531_LINK_ACTIVITY (0) and
+ VSC8531_DUPLEX_COLLISION (8).
+- load-save-gpios : GPIO used for the load/save operation of the PTP
+ hardware clock (PHC).
+

+Nokia Bluetooth Chips
+---------------------
+
+Nokia phones often come with UART connected bluetooth chips from different
+vendors and modified device API. Those devices speak a protocol named H4+
+(also known as h4p) by Nokia, which is similar to the H4 protocol from the
+Bluetooth standard. In addition to the H4 protocol it specifies two more
+UART status lines for wakeup of UART transceivers to improve power management
+and a few new packet types used to negotiate uart speed.
+
+Required properties:
+
+ - compatible: should contain "nokia,h4p-bluetooth" as well as one of the following:
+ * "brcm,bcm2048-nokia"
+ * "ti,wl1271-bluetooth-nokia"
+ - reset-gpios: GPIO specifier, used to reset the BT module (active low)
+ - bluetooth-wakeup-gpios: GPIO specifier, used to wakeup the BT module (active high)
+ - host-wakeup-gpios: GPIO specifier, used to wakeup the host processor (active high)
+ - clock-names: should be "sysclk"
+ - clocks: should contain a clock specifier for every name in clock-names
+
+Optional properties:
+
+ - None
+
+Example:
+
+/ {
+ /* controlled (enabled/disabled) directly by BT module */
+ bluetooth_clk: vctcxo {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <38400000>;
+ };
+};

+* Qualcomm QCA7000
+
+The QCA7000 is a serial-to-powerline bridge with a host interface which could
+be configured either as SPI or UART slave. This configuration is done by
+the QCA7000 firmware.
+
+(a) Ethernet over SPI
+
+In order to use the QCA7000 as SPI device it must be defined as a child of a
+SPI master in the device tree.
+
+Required properties:
+- compatible : Should be "qca,qca7000"
+- reg : Should specify the SPI chip select
+- interrupts : The first cell should specify the index of the source
+ interrupt and the second cell should specify the trigger
+ type as rising edge
+- spi-cpha : Must be set
+- spi-cpol : Must be set
+
+Optional properties:
+- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at.
+ Numbers smaller than 1000000 or greater than 16000000
+ are invalid. Missing the property will set the SPI
+ frequency to 8000000 Hertz.
+- qca,legacy-mode : Set the SPI data transfer of the QCA7000 to legacy mode.
+ In this mode the SPI master must toggle the chip select
+ between each data word. In burst mode these gaps aren't
+ necessary, which is faster. This setting depends on how
+ the QCA7000 is setup via GPIO pin strapping. If the
+ property is missing the driver defaults to burst mode.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+SPI Example:
+
+/* Freescale i.MX28 SPI master*/
+ssp2: spi@80014000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-spi";
+ pinctrl-names = "default";
+ pinctrl-0 = <&spi2_pins_a>;
+
+ qca7000: ethernet@0 {
+ compatible = "qca,qca7000";
+ reg = <0x0>;
+ interrupt-parent = <&gpio3>; /* GPIO Bank 3 */
+ interrupts = <25 0x1>; /* Index: 25, rising edge */
+ spi-cpha; /* SPI mode: CPHA=1 */
+ spi-cpol; /* SPI mode: CPOL=1 */
+ spi-max-frequency = <8000000>; /* freq: 8 MHz */
+ local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
+ };
+};
+
+(b) Ethernet over UART
+
+In order to use the QCA7000 as UART slave it must be defined as a child of a
+UART master in the device tree. It is possible to preconfigure the UART
+settings of the QCA7000 firmware, but it's not possible to change them during
+runtime.
+
+Required properties:
+- compatible : Should be "qca,qca7000"
+
+Optional properties:
+- local-mac-address : see ./ethernet.txt
+- current-speed : current baud rate of QCA7000 which defaults to 115200
+ if absent, see also ../serial/serial.yaml
+
+UART Example:
+
+/* Freescale i.MX28 UART */
+auart0: serial@8006a000 {
+ compatible = "fsl,imx28-auart", "fsl,imx23-auart";
+ reg = <0x8006a000 0x2000>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&auart0_2pins_a>;
+
+ qca7000: ethernet {
+ compatible = "qca,qca7000";
+ local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
+ current-speed = <38400>;
+ };
+};

+
+description: |
+ The BAM Data Multiplexer provides access to the network data channels
+ of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916
+ or MSM8974. It is built using a simple protocol layer on top of a DMA engine
+ (Qualcomm BAM DMA) and bidirectional interrupts to coordinate power control.
+
+ Note that this schema does not directly describe a hardware block but rather
+ a firmware convention that combines several other hardware blocks (such as the
+ DMA engine). As such it is specific to a firmware version, not a particular
+ SoC or hardware version.

+description:
+ This binding describes the Qualcomm IPA. The IPA is capable of offloading
+ certain network processing tasks (e.g. filtering, routing, and NAT) from
+ the main processor.
+
+ The IPA sits between multiple independent "execution environments,"

+ a Generic Software Interface (GSI) to each execution environment.
+ The GSI is an integral part of the IPA, but it is logically isolated

+Qualcomm Technologies EMAC Gigabit Ethernet Controller
+
+This network controller consists of two devices: a MAC and an SGMII
+internal PHY. Each device is represented by a device tree node. A phandle
+connects the MAC node to its corresponding internal phy node. Another
+phandle points to the external PHY node.
+
+Required properties:
+
+MAC node:
+- compatible : Should be "qcom,fsm9900-emac".
+- reg : Offset and length of the register regions for the device
+- interrupts : Interrupt number used by this controller
+- mac-address : The 6-byte MAC address. If present, it is the default
+ MAC address.
+- internal-phy : phandle to the internal PHY node
+- phy-handle : phandle to the external PHY node
+
+Internal PHY node:
+- compatible : Should be "qcom,fsm9900-emac-sgmii" or "qcom,qdf2432-emac-sgmii".
+- reg : Offset and length of the register region(s) for the device
+- interrupts : Interrupt number used by this controller
+
+The external phy child node:
+- reg : The phy address
+

+* Samsung 10G Ethernet driver (SXGBE)
+
+Required properties:
+- compatible: Should be "samsung,sxgbe-v2.0a"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the SXGBE interrupts
+ These interrupts are ordered by fixed and follows variable
+ transmit DMA interrupts, receive DMA interrupts and lpi interrupt.
+ index 0 - this is fixed common interrupt of SXGBE and it is always
+ available.
+ index 1 to 25 - 8 variable transmit interrupts, variable 16 receive interrupts
+ and 1 optional lpi interrupt.
+- phy-mode: String, operation mode of the PHY interface.
+ Supported values are: "sgmii", "xgmii".
+- samsung,pbl: Integer, Programmable Burst Length.
+ Supported values are 1, 2, 4, 8, 16, or 32.
+- samsung,burst-map: Integer, Program the possible bursts supported by sxgbe
+ This is an integer and represents allowable DMA bursts when fixed burst.
+ Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled.
+ When fixed length is needed for burst mode, it can be set within allowable
+ range.
+
+Optional properties:
+- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather
+ than the maximum frame size.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.

+* Synopsys DWC Ethernet QoS IP version 4.10 driver (GMAC)
+
+This binding is deprecated, but it continues to be supported, but new
+features should be preferably added to the stmmac binding document.
+
+This binding supports the Synopsys Designware Ethernet QoS (Quality Of Service)
+IP block. The IP supports multiple options for bus type, clocking and reset
+structure, and feature list. Consequently, a number of properties and list
+entries in properties are marked as optional, or only required in specific HW
+configurations.
+
+Required properties:
+- compatible: One of:
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10"
+ Represents the IP core when integrated into the Axis ARTPEC-6 SoC.
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10"
+ Represents the IP core when integrated into the NVIDIA Tegra186 SoC.
+ - "snps,dwc-qos-ethernet-4.10"
+ This combination is deprecated. It should be treated as equivalent to
+ "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10". It is supported to be
+ compatible with earlier revisions of this binding.
+- reg: Address and length of the register set for the device
+- clocks: Phandle and clock specifiers for each entry in clock-names, in the
+ same order. See ../clock/clock-bindings.txt.
+- clock-names: May contain any/all of the following depending on the IP
+ configuration, in any order:
+ - "tx"
+ The EQOS transmit path clock. The HW signal name is clk_tx_i.
+ In some configurations (e.g. GMII/RGMII), this clock also drives the PHY TX
+ path. In other configurations, other clocks (such as tx_125, rmii) may
+ drive the PHY TX path.
+ - "rx"
+ The EQOS receive path clock. The HW signal name is clk_rx_i.
+ In some configurations (e.g. GMII/RGMII), this clock is derived from the
+ PHY's RX clock output. In other configurations, other clocks (such as
+ rx_125, rmii) may drive the EQOS RX path.
+ In cases where the PHY clock is directly fed into the EQOS receive path
+ without intervening logic, the DT need not represent this clock, since it
+ is assumed to be fully under the control of the PHY device/driver. In
+ cases where SoC integration adds additional logic to this path, such as a
+ SW-controlled clock gate, this clock should be represented in DT.
+ - "slave_bus"
+ The CPU/slave-bus (CSR) interface clock. This applies to any bus type;
+ APB, AHB, AXI, etc. The HW signal name is hclk_i (AHB) or clk_csr_i (other
+ buses).
+ - "master_bus"
+ The master bus interface clock. Only required in configurations that use a
+ separate clock for the master and slave bus interfaces. The HW signal name
+ is hclk_i (AHB) or aclk_i (AXI).
+ - "ptp_ref"
+ The PTP reference clock. The HW signal name is clk_ptp_ref_i.
+ - "phy_ref_clk"
+ This clock is deprecated and should not be used by new compatible values.
+ It is equivalent to "tx".
+ - "apb_pclk"
+ This clock is deprecated and should not be used by new compatible values.
+ It is equivalent to "slave_bus".
+
+ Note: Support for additional IP configurations may require adding the
+ following clocks to this list in the future: clk_rx_125_i, clk_tx_125_i,
+ clk_pmarx_0_i, clk_pmarx1_i, clk_rmii_i, clk_revmii_rx_i, clk_revmii_tx_i.
+ Configurations exist where multiple similar clocks are used at once, e.g. all
+ of clk_rx_125_i, clk_pmarx_0_i, clk_pmarx1_i. For this reason it is best to
+ extend the binding with a separate clock-names entry for each of those RX
+ clocks, rather than repurposing the existing "rx" clock-names entry as a
+ generic/logical clock in a similar fashion to "master_bus" and "slave_bus".
+ This will allow easy support for configurations that support multiple PHY
+ interfaces using a mux, and hence need to have explicit control over
+ specific RX clocks.
+
+ The following compatible values require the following set of clocks:
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "slave_bus"
+ - "master_bus"
+ - "rx"
+ - "tx"
+ - "ptp_ref"
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "slave_bus"
+ - "master_bus"
+ - "tx"
+ - "ptp_ref"
+ - "snps,dwc-qos-ethernet-4.10" (deprecated):
+ - "phy_ref_clk"
+ - "apb_clk"
+- interrupts: Should contain the core's combined interrupt signal
+- phy-mode: See ethernet.txt file in the same directory
+- resets: Phandle and reset specifiers for each entry in reset-names, in the
+ same order. See ../reset/reset.txt.
+- reset-names: May contain any/all of the following depending on the IP
+ configuration, in any order:
+ - "eqos". The reset to the entire module. The HW signal name is hreset_n
+ (AHB) or aresetn_i (AXI).
+
+ The following compatible values require the following set of resets:
+ (the reset properties may be omitted if empty)
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "eqos".
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10":
+ - None.
+ - "snps,dwc-qos-ethernet-4.10" (deprecated):
+ - None.
+
+Optional properties:
+- dma-coherent: Present if dma operations are coherent
+- phy-reset-gpios: Phandle and specifier for any GPIO used to reset the PHY.
+ See ../gpio/gpio.txt.
+- snps,en-lpi: If present it enables use of the AXI low-power interface
+- snps,write-requests: Number of write requests that the AXI port can issue.
+ It depends on the SoC configuration.
+- snps,read-requests: Number of read requests that the AXI port can issue.
+ It depends on the SoC configuration.
+- snps,burst-map: Bitmap of allowed AXI burst lengths, with the LSB
+ representing 4, then 8 etc.
+- snps,txpbl: DMA Programmable burst length for the TX DMA
+- snps,rxpbl: DMA Programmable burst length for the RX DMA
+- snps,en-tx-lpi-clockgating: Enable gating of the MAC TX clock during
+ TX low-power mode.
+- phy-handle: See ethernet.txt file in the same directory
+- mdio device tree subnode: When the GMAC has a phy connected to its local
+ mdio, there must be device tree subnode with the following
+ required properties:
+ - compatible: Must be "snps,dwc-qos-ethernet-mdio".
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+
+ For each phy on the mdio bus, there must be a node with the following
+ fields:
+
+ - reg: phy id used to communicate to phy.
+ - device_type: Must be "ethernet-phy".
+ - fixed-mode device tree subnode: see fixed-link.txt in the same directory
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.

+Altera SOCFPGA SoC DWMAC controller
+
+This is a variant of the dwmac/stmmac driver an inherits all descriptions
+present in Documentation/devicetree/bindings/net/stmmac.txt.
+
+The device node has additional properties:
+
+Required properties:
+ - compatible : For Cyclone5/Arria5 SoCs it should contain
+ "altr,socfpga-stmmac". For Arria10/Agilex/Stratix10 SoCs
+ "altr,socfpga-stmmac-a10-s10".
+ Along with "snps,dwmac" and any applicable more detailed
+ designware version numbers documented in stmmac.txt
+ - altr,sysmgr-syscon : Should be the phandle to the system manager node that
+ encompasses the glue register, the register offset, and the register shift.
+ On Cyclone5/Arria5, the register shift represents the PHY mode bits, while
+ on the Arria10/Stratix10/Agilex platforms, the register shift represents
+ bit for each emac to enable/disable signals from the FPGA fabric to the
+ EMAC modules.
+ - altr,f2h_ptp_ref_clk use f2h_ptp_ref_clk instead of default eosc1 clock
+ for ptp ref clk. This affects all emacs as the clock is common.
+
+Optional properties:
+altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if
+ DWMAC controller is connected emac splitter.
+phy-mode: The phy mode the ethernet operates in
+altr,sgmii-to-sgmii-converter: phandle to the TSE SGMII converter
+
+This device node has additional phandle dependency, the sgmii converter:
+
+Required properties:

+STMicroelectronics SoC DWMAC glue layer controller
+
+This file documents differences between the core properties in
+Documentation/devicetree/bindings/net/stmmac.txt
+and what is needed on STi platforms to program the stmmac glue logic.
+
+The device node has following properties.
+
+Required properties:
+ - compatible : "st,stih407-dwmac"
+ - st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
+ encompases the glue register, and the offset of the control register.
+ - st,gmac_en: this is to enable the gmac into a dedicated sysctl control
+ register available on STiH407 SoC.
+ - pinctrl-0: pin-control for all the MII mode supported.
+
+Optional properties:
+ - resets : phandle pointing to the system reset controller with correct
+ reset line index for ethernet reset.
+ - st,ext-phyclk: valid only for RMII where PHY can generate 50MHz clock or
+ MAC can generate it.
+ - st,tx-retime-src: This specifies which clk is wired up to the mac for
+ retimeing tx lines. This is totally board dependent and can take one of the
+ possible values from "txclk", "clk_125" or "clkgen".
+ If not passed, the internal clock will be used by default.
+ - sti-ethclk: this is the phy clock.
+ - sti-clkconf: this is an extra sysconfig register, available in new SoCs,
+ to program the clk retiming.
+ - st,gmac_en: to enable the GMAC, this only is present in some SoCs; e.g.
+ STiH407.
+
+Example:
+
+ethernet0: dwmac@9630000 {
+ device_type = "network";
+ compatible = "st,stih407-dwmac", "snps,dwmac", "snps,dwmac-3.710";

+
+ st,syscon = <&syscfg_sbc_reg 0x80>;
+ st,gmac_en;
+ resets = <&softreset STIH407_ETH1_SOFTRESET>;
+ reset-names = "stmmaceth";
+
+ interrupts = <GIC_SPI 98 IRQ_TYPE_NONE>,
+ <GIC_SPI 99 IRQ_TYPE_NONE>,
+ <GIC_SPI 100 IRQ_TYPE_NONE>;
+ interrupt-names = "macirq", "eth_wake_irq", "eth_lpi";
+
+ snps,pbl = <32>;
+ snps,mixed-burst;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_rgmii1>;
+
+ clock-names = "stmmaceth", "sti-ethclk";
+ clocks = <&CLK_S_C0_FLEXGEN CLK_EXT2F_A9>,
+ <&CLK_S_C0_FLEXGEN CLK_ETH_PHY>;

+ This documents the binding structure and common properties for serial
+ attached TI Bluetooth devices. The following chips are included in this
+ binding:
+
+ * TI CC256x Bluetooth devices
+ * TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices
+
+ TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
+ and GPS over what's called "shared transport". The shared transport is
+ standard BT HCI protocol with additional channels for the other functions.
+
+ TI WiLink devices also have a separate WiFi interface as described in
+ wireless/ti,wlcore.yaml.
+
+ This bindings follows the UART slave device binding in ../serial/serial.yaml.

+title: The TI AM654x/J721E Common Platform Time Sync (CPTS) module

+ - Sekhar Nori <nsekhar@ti.com>
+
+description: |+
+ The TI AM654x/J721E CPTS module is used to facilitate host control of time
+ sync operations.
+ Main features of CPTS module are
+ - selection of multiple external clock sources
+ - Software control of time sync events via interrupt or polling
+ - 64-bit timestamp mode in ns with PPM and nudge adjustment.
+ - hardware timestamp push inputs (HWx_TS_PUSH)
+ - timestamp counter compare output (TS_COMP)
+ - timestamp counter bit output (TS_SYNC)
+ - periodic Generator function outputs (TS_GENFx)
+ - Ethernet Enhanced Scheduled Traffic Operations (CPTS_ESTFn) (TSN)
+ - external hardware timestamp push inputs (HWx_TS_PUSH) timestamping
+
+ Depending on integration it enables compliance with the IEEE 1588-2008
+ standard for a precision clock synchronization protocol, Ethernet Enhanced
+ Scheduled Traffic Operations (CPTS_ESTFn) and PCIe Subsystem Precision Time
+ Measurement (PTM).
+
+ TI AM654x/J721E SoCs has several similar CPTS modules integrated into the
+ different parts of the system which could be synchronized with each other
+ - Main CPTS
+ - MCU CPSW CPTS with IEEE 1588-2008 support
+ - PCIe subsystem CPTS for PTM support
+
+ Depending on CPTS module integration and when CPTS is integral part of
+ another module (MCU CPSW for example) "compatible" and "reg" can
+ be omitted - parent module is fully responsible for CPTS enabling and
+ configuration.

+------
+
+This node provides properties for controlling the Marvell SDIO/PCIE wireless device.
+The node is expected to be specified as a child node to the SDIO/PCIE controller that
+connects the device to the system.
+
+Required properties:
+
+ - compatible : should be one of the following:
+ * "marvell,sd8787"
+ * "marvell,sd8897"
+ * "marvell,sd8978"
+ * "marvell,sd8997"
+ * "nxp,iw416"
+ * "pci11ab,2b42"
+ * "pci1b4b,2b42"
+
+Optional properties:
+
+ - marvell,caldata* : A series of properties with marvell,caldata prefix,
+ represent calibration data downloaded to the device during
+ initialization. This is an array of unsigned 8-bit values.
+ the properties should follow below property name and
+ corresponding array length:
+ "marvell,caldata-txpwrlimit-2g" (length = 566).
+ "marvell,caldata-txpwrlimit-5g-sub0" (length = 502).
+ "marvell,caldata-txpwrlimit-5g-sub1" (length = 688).
+ "marvell,caldata-txpwrlimit-5g-sub2" (length = 750).
+ "marvell,caldata-txpwrlimit-5g-sub3" (length = 502).
+ - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured
+ to firmware. Firmware will wakeup the host using this pin
+ during suspend/resume.
+ - interrupts : interrupt pin number to the cpu. driver will request an irq based on
+ this interrupt number. during system suspend, the irq will be enabled
+ so that the wifi chip can wakeup host platform under certain condition.
+ during system resume, the irq will be disabled to make sure
+ unnecessary interrupt is not received.
+ - vmmc-supply: a phandle of a regulator, supplying VCC to the card
+ - mmc-pwrseq: phandle to the MMC power sequence node. See "mmc-pwrseq-*"
+ for documentation of MMC power sequence bindings.
+
+Example:
+
+Tx power limit calibration data is configured in below example.
+The calibration data is an array of unsigned values, the length
+can vary between hw versions.
+IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured
+so that firmware can wakeup host using this device side pin.

+description: >
+ Support for the Wifi chip WFxxx from Silicon Labs. Currently, the only device
+ from the WFxxx series is the WF200 described here:
+ https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf
+
+ The WF200 can be connected via SPI or via SDIO.
+
+ For SDIO:
+
+ Declaring the WFxxx chip in device tree is mandatory (usually, the VID/PID is
+ sufficient for the SDIO devices).
+
+ It is recommended to declare a mmc-pwrseq on SDIO host above WFx. Without
+ it, you may encounter issues during reboot. The mmc-pwrseq should be
+ compatible with mmc-pwrseq-simple. Please consult
+ Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
+ information.

+* Wiznet w5x00
+
+This is a standalone 10/100 MBit Ethernet controller with SPI interface.
+
+For each device connected to a SPI bus, define a child node within
+the SPI master node.
+
+Required properties:
+- compatible: Should be one of the following strings:
+ "wiznet,w5100"
+ "wiznet,w5200"
+ "wiznet,w5500"
+- reg: Specify the SPI chip select the chip is wired to.
+- interrupts: Specify the interrupt index within the interrupt controller (referred
+ to above in interrupt-parent) and interrupt type. w5x00 natively
+ generates falling edge interrupts, however, additional board logic
+ might invert the signal.
+- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
+- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
+ see also generic and your platform specific pinctrl binding
+ documentation.
+
+Optional properties:
+- spi-max-frequency: Maximum frequency of the SPI bus when accessing the w5500.
+ According to the w5500 datasheet, the chip allows a maximum of 80 MHz, however,
+ board designs may need to limit this value.
+- local-mac-address: See ethernet.txt in the same directory.
+
+
+Example (for Raspberry Pi with pin control stuff for GPIO irq):
+

+==============================================================================
+NUMA binding description.
+==============================================================================
+
+==============================================================================
+1 - Introduction
+==============================================================================
+
+Systems employing a Non Uniform Memory Access (NUMA) architecture contain
+collections of hardware resources including processors, memory, and I/O buses,
+that comprise what is commonly known as a NUMA node.
+Processor accesses to memory within the local NUMA node is generally faster
+than processor accesses to memory outside of the local NUMA node.
+DT defines interfaces that allow the platform to convey NUMA node
+topology information to OS.
+
+==============================================================================
+2 - numa-node-id
+==============================================================================
+
+For the purpose of identification, each NUMA node is associated with a unique
+token known as a node id. For the purpose of this binding
+a node id is a 32-bit integer.
+
+A device node is associated with a NUMA node by the presence of a
+numa-node-id property which contains the node id of the device.
+
+Example:
+ /* numa node 0 */
+ numa-node-id = <0>;
+
+ /* numa node 1 */
+ numa-node-id = <1>;
+
+==============================================================================
+3 - distance-map
+==============================================================================
+
+The optional device tree node distance-map describes the relative
+distance (memory latency) between all numa nodes.
+
+- compatible : Should at least contain "numa-distance-map-v1".
+
+- distance-matrix
+ This property defines a matrix to describe the relative distances
+ between all numa nodes.
+ It is represented as a list of node pairs and their relative distance.
+
+ Note:
+ 1. Each entry represents distance from first node to second node.
+ The distances are equal in either direction.
+ 2. The distance from a node to self (local distance) is represented
+ with value 10 and all internode distance should be represented with
+ a value greater than 10.
+ 3. distance-matrix should have entries in lexicographical ascending
+ order of nodes.
+ 4. There must be only one device node distance-map which must
+ reside in the root node.
+ 5. If the distance-map node is not present, a default
+ distance-matrix is used.
+
+Example:
+ 4 nodes connected in mesh/ring topology as below,
+
+ 0_______20______1
+ | |
+ | |
+ 20 20
+ | |
+ | |
+ |_______________|
+ 3 20 2
+
+ if relative distance for each hop is 20,
+ then internode distance would be,
+ 0 -> 1 = 20
+ 1 -> 2 = 20
+ 2 -> 3 = 20
+ 3 -> 0 = 20
+ 0 -> 2 = 40
+ 1 -> 3 = 40
+
+ and dt presentation for this distance matrix is,
+
+ distance-map {
+ compatible = "numa-distance-map-v1";
+ distance-matrix = <0 0 10>,
+ <0 1 20>,
+ <0 2 40>,
+ <0 3 20>,
+ <1 0 20>,
+ <1 1 10>,
+ <1 2 20>,
+ <1 3 40>,
+ <2 0 40>,
+ <2 1 20>,
+ <2 2 10>,
+ <2 3 20>,
+ <3 0 20>,
+ <3 1 40>,
+ <3 2 20>,
+ <3 3 10>;
+ };
+
+==============================================================================
+4 - Empty memory nodes
+==============================================================================
+
+Empty memory nodes, which no memory resides in, are allowed. There are no
+device nodes for these empty memory nodes. However, the NUMA node IDs and
+distance maps are still valid and memory may be added into them through
+hotplug afterwards.
+
+Example:
+
+ memory@0 {
+ device_type = "memory";
+ reg = <0x0 0x0 0x0 0x80000000>;
+ numa-node-id = <0>;
+ };
+
+ memory@80000000 {
+ device_type = "memory";
+ reg = <0x0 0x80000000 0x0 0x80000000>;
+ numa-node-id = <1>;
+ };
+
+ /* Empty memory node 2 and 3 */
+ distance-map {
+ compatible = "numa-distance-map-v1";
+ distance-matrix = <0 0 10>,
+ <0 1 20>,
+ <0 2 40>,
+ <0 3 20>,
+ <1 0 20>,
+ <1 1 10>,
+ <1 2 20>,
+ <1 3 40>,
+ <2 0 40>,
+ <2 1 20>,
+ <2 2 10>,
+ <2 3 20>,
+ <3 0 20>,
+ <3 1 40>,
+ <3 2 20>,
+ <3 3 10>;
+ };
+
+==============================================================================
+5 - Example dts

+Dual socket system consists of 2 boards connected through ccn bus and
+each board having one socket/soc of 8 cpus, memory and pci bus.

+title: U-Boot environment variables
+
+description: |
+ U-Boot uses environment variables to store device parameters and
+ configuration. They may be used for booting process, setup or keeping end user
+ info.
+
+ Data is stored using U-Boot specific formats (variant specific header and NUL
+ separated key-value pairs).
+
+ Environment data can be stored on various storage entities, e.g.:
+ 1. Raw flash partition
+ 2. UBI volume
+
+ This binding allows marking storage device (as containing env data) and
+ specifying used format.
+
+ Right now only flash partition case is covered but it may be extended to e.g.
+ UBI volumes in the future.
+
+ Variables can be defined as NVMEM device subnodes.

+OpenRISC Generic SoC
+====================
+
+Boards and FPGA SoC's which support the OpenRISC standard platform. The
+platform essentially follows the conventions of the OpenRISC architecture
+specification, however some aspects, such as the boot protocol have been defined
+by the Linux port.
+
+Required properties
+-------------------
+ - compatible: Must include "opencores,or1ksim"
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Since the topology may
+be probed via CPS, it is not necessary to specify secondary CPUs. Required
+properties:
+ - compatible: Must be "opencores,or1200-rtlsvn481".
+ - reg: CPU number.
+ - clock-frequency: The CPU clock frequency in Hz.
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cpu@0 {
+ compatible = "opencores,or1200-rtlsvn481";
+ reg = <0>;
+ clock-frequency = <20000000>;
+ };
+ };
+
+
+Boot protocol
+-------------
+The bootloader may pass the following arguments to the kernel:
+ - r3: address of a flattened device-tree blob or 0x0.

+description: |
+ In certain Qualcomm Technologies, Inc. SoCs like APQ8096 and MSM8996,
+ the CPU frequencies subset and voltage value of each OPP varies based on
+ the silicon variant in use.
+ Qualcomm Technologies, Inc. Process Voltage Scaling Tables
+ defines the voltage and frequency value based on the speedbin blown in
+ the efuse combination.
+ The qcom-cpufreq-nvmem driver reads the efuse value from the SoC to provide
+ the OPP framework with required information (existing HW bitmap).
+ This is used to determine the voltage and frequency value for each OPP of
+ operating-points-v2 table when it is parsed by the OPP framework.

+description:
+ OMAP5, DRA7, and AM57 families of SoCs have Class 0 AVS eFuse
+ registers, which contain OPP-specific voltage information tailored
+ for the specific device. This binding provides the information
+ needed to describe such a hardware values and relate them to program
+ the primary regulator during an OPP transition.
+
+ Also, some supplies may have an associated vbb-supply, an Adaptive
+ Body Bias regulator, which must transition in a specific sequence
+ w.r.t the vdd-supply and clk when making an OPP transition. By
+ supplying two regulators to the device that will undergo OPP
+ transitions, we can use the multi-regulator support implemented by
+ the OPP core to describe both regulators the platform needs. The
+ OPP core binding Documentation/devicetree/bindings/opp/opp-v2.yaml
+ provides further information (refer to Example 4 Handling multiple
+ regulators).

+description: |
+ The Apple PCIe host controller is a PCIe host controller with
+ multiple root ports present in Apple ARM SoC platforms, including
+ various iPhone and iPad devices and the "Apple Silicon" Macs.
+ The controller incorporates Synopsys DesigWare PCIe logic to
+ implements its root ports. But the ATU found on most DesignWare
+ PCIe host bridges is absent.
+
+ All root ports share a single ECAM space, but separate GPIOs are
+ used to take the PCI devices on those ports out of reset. Therefore
+ the standard "reset-gpios" and "max-link-speed" properties appear on
+ the child nodes that represent the PCI bridges that correspond to
+ the individual root ports.
+
+ MSIs are handled by the PCIe controller and translated into regular
+ interrupts. A range of 32 MSIs is provided. These 32 MSIs can be
+ distributed over the root ports as the OS sees fit by programming
+ the PCIe controller's port registers.

+* Axis ARTPEC-6 PCIe interface
+
+This PCIe host controller is based on the Synopsys DesignWare PCIe IP
+and thus inherits all the common properties defined in snps,dw-pcie.yaml.
+
+Required properties:
+- compatible: "axis,artpec6-pcie", "snps,dw-pcie" for ARTPEC-6 in RC mode;
+ "axis,artpec6-pcie-ep", "snps,dw-pcie" for ARTPEC-6 in EP mode;
+ "axis,artpec7-pcie", "snps,dw-pcie" for ARTPEC-7 in RC mode;
+ "axis,artpec7-pcie-ep", "snps,dw-pcie" for ARTPEC-7 in EP mode;
+- reg: base addresses and lengths of the PCIe controller (DBI),
+ the PHY controller, and configuration address space.
+- reg-names: Must include the following entries:
+ - "dbi"
+ - "phy"
+ - "config"
+- interrupts: A list of interrupt outputs of the controller. Must contain an
+ entry for each entry in the interrupt-names property.
+- interrupt-names: Must include the following entries:
+ - "msi": The interrupt that is asserted when an MSI is received
+- axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
+ used to enable and control the Synopsys IP.

+ activated. It's based on the DWC RC PCIe v4.60a IP-core, which is configured
+ to have just a single Root Port function and is capable of establishing the
+ link up to Gen.3 speed on x4 lanes. It doesn't have embedded clock and reset
+ control module, so the proper interface initialization is supposed to be

+title: Faraday Technology FTPCI100 PCI Host Bridge
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ This PCI bridge is found inside that Cortina Systems Gemini SoC platform and
+ is a generic IP block from Faraday Technology. It exists in two variants:
+ plain and dual PCI. The plain version embeds a cascading interrupt controller
+ into the host bridge. The dual version routes the interrupts to the host
+ chips interrupt controller.
+ The host controller appear on the PCI bus with vendor ID 0x159b (Faraday
+ Technology) and product ID 0x4321.
+ I/O space considerations:
+ The plain variant has 128MiB of non-prefetchable memory space, whereas the
+ "dual" variant has 64MiB. Take this into account when describing the ranges.
+
+ Interrupt map considerations:
+
+ The "dual" variant will get INT A, B, C, D from the system interrupt controller
+ and should point to respective interrupt in that controller in its interrupt-map.
+
+ The code which is the only documentation of how the Faraday PCI (the non-dual
+ variant) interrupts assigns the default interrupt mapping/swizzling has
+ typically been like this, doing the swizzling on the interrupt controller side
+ rather than in the interconnect:
+
+ interrupt-map-mask = <0xf800 0 0 7>;
+ interrupt-map =
+ <0x4800 0 0 1 &pci_intc 0>, /* Slot 9 */
+ <0x4800 0 0 2 &pci_intc 1>,
+ <0x4800 0 0 3 &pci_intc 2>,

+* Bus Enumeration by Freescale PCI-X Agent
+
+Typically any Freescale PCI-X bridge hardware strapped into Agent mode
+is prevented from enumerating the bus. The PrPMC form-factor requires
+all mezzanines to be PCI-X Agents, but one per system may still
+enumerate the bus.
+
+The property defined below will allow a PCI-X bridge to be used for bus
+enumeration despite being strapped into Agent mode.
+
+Required properties:
+- fsl,pci-agent-force-enum : There is no value associated with this
+ property. The property itself is treated as a boolean.
+
+Example:
+
+ /* PCI-X bridge known to be PrPMC Monarch */
+ pci0: pci@ef008000 {
+ fsl,pci-agent-force-enum;
+ #interrupt-cells = <1>;
+ #size-cells = <2>;

+description: |
+ Firmware-initialised PCI host controllers and PCI emulations, such as the
+ virtio-pci implementations found in kvmtool and other para-virtualised
+ systems, do not require driver support for complexities such as regulator
+ and clock management. In fact, the controller may not even require the
+ configuration of a control interface by the operating system, instead
+ presenting a set of fixed windows describing a subset of IO, Memory and
+ Configuration Spaces.
+
+ Configuration Space is assumed to be memory-mapped (as opposed to being
+ accessed via an ioport) and laid out with a direct correspondence to the
+ geography of a PCI bus address by concatenating the various components to
+ form an offset.
+
+ For CAM, this 24-bit offset is:
+
+ cfg_offset(bus, device, function, register) =
+ bus << 16 | device << 11 | function << 8 | register
+
+ While ECAM extends this by 4 bits to accommodate 4k of function space:
+
+ cfg_offset(bus, device, function, register) =
+ bus << 20 | device << 15 | function << 12 | register
+
+properties:
+ compatible:

+ respectively). May also have more specific compatibles.

+

+Freescale Layerscape PCIe controller
+
+This PCIe host controller is based on the Synopsys DesignWare PCIe IP
+and thus inherits all the common properties defined in snps,dw-pcie.yaml.
+
+This controller derives its clocks from the Reset Configuration Word (RCW)
+which is used to describe the PLL settings at the time of chip-reset.
+
+Also as per the available Reference Manuals, there is no specific 'version'
+register available in the Freescale PCIe controller register set,
+which can allow determining the underlying DesignWare PCIe controller version
+information.
+
+Required properties:

+- interrupt-names: It could include the following entries:
+ "aer": Used for interrupt line which reports AER events when

+ "pme": Used for interrupt line which reports PME events when
+ non MSI/MSI-X/INTx mode is used
+ "intr": Used for SoCs(like ls2080a, lx2160a, ls2080a, ls2088a, ls1088a)
+ which has a single interrupt line for miscellaneous controller
+ events(could include AER and PME events).
+- fsl,pcie-scfg: Must include two entries.
+ The first entry must be a link to the SCFG device node
+ The second entry is the physical PCIe controller index starting from '0'.
+ This is used to get SCFG PEXN registers
+- dma-coherent: Indicates that the hardware IP block can ensure the coherency

+NXP Layerscape PCIe Gen4 controller
+
+This PCIe controller is based on the Mobiveil PCIe IP and thus inherits all
+the common properties defined in mobiveil-pcie.txt.
+
+Required properties:
+- compatible: should contain the platform identifier such as:
+ "fsl,lx2160a-pcie"
+- reg: base addresses and lengths of the PCIe controller register blocks.
+ "csr_axi_slave": Bridge config registers
+ "config_axi_slave": PCIe controller registers
+- interrupts: A list of interrupt outputs of the controller. Must contain an
+ entry for each entry in the interrupt-names property.
+- interrupt-names: It could include the following entries:
+ "intr": The interrupt that is asserted for controller interrupts
+ "aer": Asserted for aer interrupt when chip support the aer interrupt with
+ none MSI/MSI-X/INTx mode,but there is interrupt line for aer.
+ "pme": Asserted for pme interrupt when chip support the pme interrupt with
+ none MSI/MSI-X/INTx mode,but there is interrupt line for pme.
+- dma-coherent: Indicates that the hardware IP block can ensure the coherency
+ of the data transferred from/to the IP block. This can avoid the software
+ cache flush/invalid actions, and improve the performance significantly.
+- msi-parent : See the generic MSI binding described in
+ Documentation/devicetree/bindings/interrupt-controller/msi.txt.

+* Marvell EBU PCIe interfaces
+
+Mandatory properties:
+
+- compatible: one of the following values:
+ marvell,armada-370-pcie
+ marvell,armada-xp-pcie
+ marvell,dove-pcie
+ marvell,kirkwood-pcie
+- #address-cells, set to <3>
+- #size-cells, set to <2>
+- #interrupt-cells, set to <1>
+- bus-range: PCI bus numbers covered
+- device_type, set to "pci"
+- ranges: ranges describing the MMIO registers to control the PCIe
+ interfaces, and ranges describing the MBus windows needed to access
+ the memory and I/O regions of each PCIe interface.
+- msi-parent: Link to the hardware entity that serves as the Message
+ Signaled Interrupt controller for this PCI controller.
+
+The ranges describing the MMIO registers have the following layout:
+
+ 0x82000000 0 r MBUS_ID(0xf0, 0x01) r 0 s
+
+where:
+
+ * r is a 32-bits value that gives the offset of the MMIO
+ registers of this PCIe interface, from the base of the internal
+ registers.
+
+ * s is a 32-bits value that give the size of this MMIO
+ registers area. This range entry translates the '0x82000000 0 r' PCI
+ address into the 'MBUS_ID(0xf0, 0x01) r' CPU address, which is part
+ of the internal register window (as identified by MBUS_ID(0xf0,
+ 0x01)).
+
+The ranges describing the MBus windows have the following layout:
+
+ 0x8t000000 s 0 MBUS_ID(w, a) 0 1 0
+
+where:
+
+ * t is the type of the MBus window (as defined by the standard PCI DT
+ bindings), 1 for I/O and 2 for memory.
+
+ * s is the PCI slot that corresponds to this PCIe interface
+
+ * w is the 'target ID' value for the MBus window
+
+ * a the 'attribute' value for the MBus window.
+
+Since the location and size of the different MBus windows is not fixed in
+hardware, and only determined in runtime, those ranges cover the full first
+4 GB of the physical address space, and do not translate into a valid CPU
+address.
+
+In addition, the device tree node must have sub-nodes describing each
+PCIe interface, having the following mandatory properties:
+
+- reg: used only for interrupt mapping, so only the first four bytes
+ are used to refer to the correct bus number and device number.
+- assigned-addresses: reference to the MMIO registers used to control
+ this PCIe interface.
+- clocks: the clock associated to this PCIe interface
+- marvell,pcie-port: the physical PCIe port number
+- status: either "disabled" or "okay"
+- device_type, set to "pci"
+- #address-cells, set to <3>
+- #size-cells, set to <2>
+- #interrupt-cells, set to <1>
+- ranges, translating the MBus windows ranges of the parent node into
+ standard PCI addresses.
+- interrupt-map-mask and interrupt-map, standard PCI properties to
+ define the mapping of the PCIe interface to interrupt numbers.
+
+and the following optional properties:
+- marvell,pcie-lane: the physical PCIe lane number, for ports having
+ multiple lanes. If this property is not found, we assume that the
+ value is 0.
+- num-lanes: number of SerDes PCIe lanes for this link (1 or 4)
+- reset-gpios: optional GPIO to PERST#
+- reset-delay-us: delay in us to wait after reset de-assertion, if not
+ specified will default to 100ms, as required by the PCIe specification.
+- interrupt-names: list of interrupt names, supported are:
+ - "intx" - interrupt line triggered by one of the legacy interrupt
+- interrupts or interrupts-extended: List of the interrupt sources which
+ corresponding to the "interrupt-names". If non-empty then also additional
+ 'interrupt-controller' subnode must be defined.

+
+description: |
+ This PCIe controller is based on the Synopsys DesignWare PCIe IP and thus
+ inherits all the common properties defined in snps,dw-pcie-ep.yaml. Some
+ of the controller instances are dual mode; they can work either in Root
+ Port mode or Endpoint mode but one at a time.
+
+ On Tegra194, controllers C0, C4 and C5 support Endpoint mode.
+ On Tegra234, controllers C5, C6, C7 and C10 support Endpoint mode.
+
+ Note: On Tegra194's P2972-0000 platform, only C5 controller can be enabled to
+ operate in the Endpoint mode because of the way the platform is designed.

+description: |
+ This PCIe controller is based on the Synopsys DesignWare PCIe IP and thus
+ inherits all the common properties defined in snps,dw-pcie.yaml. Some of
+ the controller instances are dual mode where in they can work either in
+ Root Port mode or Endpoint mode but one at a time.
+
+ See nvidia,tegra194-pcie-ep.yaml for details on the Endpoint mode device
+ tree bindings.

+
+Note that devices on the PCI bus are dynamically discovered using PCI's bus
+enumeration and therefore don't need corresponding device nodes in DT. However
+if a device on the PCI bus provides a non-probeable bus such as I2C or SPI,
+device nodes need to be added in order to allow the bus' children to be
+instantiated at the proper location in the operating system's device tree (as
+illustrated by the optional nodes in the example above).

+* Marvell Armada 7K/8K PCIe interface
+
+This PCIe host controller is based on the Synopsys DesignWare PCIe IP
+and thus inherits all the common properties defined in snps,dw-pcie.yaml.
+
+Required properties:
+- compatible: "marvell,armada8k-pcie"
+- reg: must contain two register regions
+ - the control register region
+ - the config space region
+- reg-names:
+ - "ctrl" for the control register region
+ - "config" for the config space region
+- interrupts: Interrupt specifier for the PCIe controller
+- clocks: reference to the PCIe controller clocks
+- clock-names: mandatory if there is a second clock, in this case the
+ name must be "core" for the first clock and "reg" for the second
+ one
+
+Optional properties:
+- phys: phandle(s) to PHY node(s) following the generic PHY bindings.
+ Either 1, 2 or 4 PHYs might be needed depending on the number of
+ PCIe lanes.
+- phy-names: names of the PHYs corresponding to the number of lanes.
+ Must be "cp0-pcie0-x4-lane0-phy", "cp0-pcie0-x4-lane1-phy" for
+ 2 PHYs.
+
+Example:
+
+ pcie@f2600000 {

+This document describes the generic device tree binding for describing the
+relationship between PCI(e) devices and IOMMU(s).
+
+Each PCI(e) device under a root complex is uniquely identified by its Requester
+ID (AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
+Function number.
+
+For the purpose of this document, when treated as a numeric value, a RID is
+formatted such that:
+
+* Bits [15:8] are the Bus number.
+* Bits [7:3] are the Device number.
+* Bits [2:0] are the Function number.
+* Any other bits required for padding must be zero.
+
+IOMMUs may distinguish PCI devices through sideband data derived from the
+Requester ID. While a given PCI device can only master through one IOMMU, a
+root complex may split masters across a set of IOMMUs (e.g. with one IOMMU per
+bus).
+
+The generic 'iommus' property is insufficient to describe this relationship,
+and a mechanism is required to map from a PCI device to its IOMMU and sideband
+data.
+
+For generic IOMMU bindings, see
+Documentation/devicetree/bindings/iommu/iommu.txt.

+This document describes the generic device tree binding for describing the
+relationship between PCI devices and MSI controllers.
+
+Each PCI device under a root complex is uniquely identified by its Requester ID
+(AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
+Function number.
+
+For the purpose of this document, when treated as a numeric value, a RID is
+formatted such that:
+
+* Bits [15:8] are the Bus number.
+* Bits [7:3] are the Device number.
+* Bits [2:0] are the Function number.
+* Any other bits required for padding must be zero.
+
+MSIs may be distinguished in part through the use of sideband data accompanying
+writes. In the case of PCI devices, this sideband data may be derived from the
+Requester ID. A mechanism is required to associate a device with both the MSI
+controllers it can address, and the sideband data that will be associated with
+its writes to those controllers.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+
+PCI root complex
+================
+
+Optional properties
+-------------------
+
+- msi-map: Maps a Requester ID to an MSI controller and associated
+ msi-specifier data. The property is an arbitrary number of tuples of
+ (rid-base,msi-controller,msi-base,length), where:
+
+ * rid-base is a single cell describing the first RID matched by the entry.
+
+ * msi-controller is a single phandle to an MSI controller
+
+ * msi-base is an msi-specifier describing the msi-specifier produced for the
+ first RID matched by the entry.
+
+ * length is a single cell describing how many consecutive RIDs are matched
+ following the rid-base.
+
+ Any RID r in the interval [rid-base, rid-base + length) is associated with
+ the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
+
+- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
+ to an msi-specifier per the msi-map property.
+
+- msi-parent: Describes the MSI parent of the root complex itself. Where
+ the root complex and MSI controller do not pass sideband data with MSI
+ writes, this property may be used to describe the MSI controller(s)
+ used by PCI devices under the root complex, if defined as such in the
+ binding for the root complex.
+

+PCI bus bridges have standardized Device Tree bindings:
+
+PCI Bus Binding to: IEEE Std 1275-1994
+https://www.devicetree.org/open-firmware/bindings/pci/pci2_1.pdf
+
+And for the interrupt mapping part:
+
+Open Firmware Recommended Practice: Interrupt Mapping
+https://www.devicetree.org/open-firmware/practice/imap/imap0_9d.pdf
+
+Additionally to the properties specified in the above standards a host bridge
+driver implementation may support the following properties:
+
+- linux,pci-domain:
+ If present this property assigns a fixed PCI domain number to a host bridge,
+ otherwise an unstable (across boots) unique number will be assigned.
+ It is required to either not set this property at all or set it for all
+ host bridges in the system, otherwise potentially conflicting domain numbers
+ may be assigned to root buses behind different host bridges. The domain
+ number for each host bridge in the system must be unique.
+- max-link-speed:
+ If present this property specifies PCI gen for link capability. Host
+ drivers could add this as a strategy to avoid unnecessary operation for
+ unsupported link speed, for instance, trying to do training for
+ unsupported link speed, etc. Must be '4' for gen4, '3' for gen3, '2'
+ for gen2, and '1' for gen1. Any other values are invalid.
+- reset-gpios:
+ If present this property specifies PERST# GPIO. Host drivers can parse the
+ GPIO and apply fundamental reset to endpoints.
+- supports-clkreq:
+ If present this property specifies that CLKREQ signal routing exists from
+ root port to downstream device and host bridge drivers can do programming
+ which depends on CLKREQ signal existence. For example, programming root port
+ not to advertise ASPM L1 Sub-States support if there is no CLKREQ signal.
+
+PCI-PCI Bridge properties
+-------------------------
+
+PCIe root ports and switch ports may be described explicitly in the device
+tree, as children of the host bridge node. Even though those devices are
+discoverable by probing, it might be necessary to describe properties that
+aren't provided by standard PCIe capabilities.
+
+Required properties:
+
+- reg:
+ Identifies the PCI-PCI bridge. As defined in the IEEE Std 1275-1994
+ document, it is a five-cell address encoded as (phys.hi phys.mid
+ phys.lo size.hi size.lo). phys.hi should contain the device's BDF as
+ 0b00000000 bbbbbbbb dddddfff 00000000. The other cells should be zero.
+
+ The bus number is defined by firmware, through the standard bridge
+ configuration mechanism. If this port is a switch port, then firmware
+ allocates the bus number and writes it into the Secondary Bus Number
+ register of the bridge directly above this port. Otherwise, the bus
+ number of a root port is the first number in the bus-range property,
+ defaulting to zero.
+
+ If firmware leaves the ARI Forwarding Enable bit set in the bridge
+ above this port, then phys.hi contains the 8-bit function number as
+ 0b00000000 bbbbbbbb ffffffff 00000000. Note that the PCIe specification
+ recommends that firmware only leaves ARI enabled when it knows that the
+ OS is ARI-aware.
+
+Optional properties:
+
+- external-facing:
+ When present, the port is external-facing. All bridges and endpoints
+ downstream of this port are external to the machine. The OS can, for
+ example, use this information to identify devices that cannot be
+ trusted with relaxed DMA protection, as users could easily attach
+ malicious devices to this port.
+
+Example:
+
+pcie@10000000 {
+ compatible = "pci-host-ecam-generic";
+ ...
+ pcie@0008 {
+ /* Root port 00:01.0 is external-facing */
+ reg = <0x00000800 0 0 0 0>;
+ external-facing;
+ };
+};

+* Mediatek/Ralink RT3883 PCI controller
+
+1) Main node
+
+ Required properties:
+
+ - compatible: must be "ralink,rt3883-pci"
+
+ - reg: specifies the physical base address of the controller and
+ the length of the memory mapped region.
+
+ - #address-cells: specifies the number of cells needed to encode an
+ address. The value must be 1.
+
+ - #size-cells: specifies the number of cells used to represent the size
+ of an address. The value must be 1.
+
+ - ranges: specifies the translation between child address space and parent
+ address space
+
+ Optional properties:
+
+ - status: indicates the operational status of the device.
+ Value must be either "disabled" or "okay".
+
+2) Child nodes
+
+ The main node must have two child nodes which describes the built-in
+ interrupt controller and the PCI host bridge.
+
+ a) Interrupt controller:
+
+ Required properties:
+
+ - interrupt-controller: identifies the node as an interrupt controller
+
+ - #address-cells: specifies the number of cells needed to encode an
+ address. The value must be 0. As such, 'interrupt-map' nodes do not
+ have to specify a parent unit address.
+
+ - #interrupt-cells: specifies the number of cells needed to encode an
+ interrupt source. The value must be 1.
+
+ - interrupts: specifies the interrupt source of the parent interrupt
+ controller. The format of the interrupt specifier depends on the
+ parent interrupt controller.
+
+ b) PCI host bridge:
+
+ Required properties:
+
+ - #address-cells: specifies the number of cells needed to encode an
+ address. The value must be 0.
+
+ - #size-cells: specifies the number of cells used to represent the size
+ of an address. The value must be 2.
+
+ - #interrupt-cells: specifies the number of cells needed to encode an
+ interrupt source. The value must be 1.
+
+ - device_type: must be "pci"
+
+ - bus-range: PCI bus numbers covered
+
+ - ranges: specifies the ranges for the PCI memory and I/O regions
+
+ - interrupt-map-mask,
+ - interrupt-map: standard PCI properties to define the mapping of the
+ PCI interface to interrupt numbers.
+
+ The PCI host bridge node might have additional sub-nodes representing
+ the onboard PCI devices/PCI slots. Each such sub-node must have the
+ following mandatory properties:
+
+ - reg: used only for interrupt mapping, so only the first four bytes
+ are used to refer to the correct bus number and device number.
+
+ - device_type: must be "pci"
+
+ If a given sub-node represents a PCI bridge it must have following
+ mandatory properties as well:
+
+ - #address-cells: must be set to <3>
+
+ - #size-cells: must set to <2>
+
+ - #interrupt-cells: must be set to <1>
+
+ - interrupt-map-mask,
+ - interrupt-map: standard PCI properties to define the mapping of the
+ PCI interface to interrupt numbers.
+
+ Besides the required properties the sub-nodes may have these optional
+ properties:
+
+ - status: indicates the operational status of the sub-node.
+ Value must be either "disabled" or "okay".
+
+3) Example:

+ #interrupt-cells = <1>;
+
+ device_type = "pci";

+
+ host-bridge {
+ pci-bridge@1 {

+ Should be "ti,dra726-pcie-ep" for dra72x in EP mode
+ - phys : list of PHY specifiers (used by generic PHY framework)
+ - phy-names : must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
+ number of PHYs as specified in *phys* property.
+ - ti,hwmods : Name of the hwmod associated to the pcie, "pcie<X>",
+ where <X> is the instance number of the pcie from the HW spec.
+ - num-lanes as specified in ../snps,dw-pcie.yaml
+ - ti,syscon-lane-sel : phandle/offset pair. Phandle to the system control
+ module and the register offset to specify lane
+ selection.
+
+HOST MODE
+=========
+ - reg : Two register ranges as listed in the reg-names property
+ - reg-names : The first entry must be "ti-conf" for the TI-specific registers
+ The second entry must be "rc-dbics" for the DesignWare PCIe
+ registers
+ The third entry must be "config" for the PCIe configuration space
+ - interrupts : Two interrupt entries must be specified. The first one is for
+ main interrupt line and the second for MSI interrupt line.
+ - #address-cells,
+ #size-cells,
+ #interrupt-cells,
+ device_type,
+ ranges,
+ interrupt-map-mask,
+ interrupt-map : as specified in ../snps,dw-pcie.yaml
+ - ti,syscon-unaligned-access: phandle to the syscon DT node. The 1st argument
+ should contain the register offset within syscon
+ and the 2nd argument should contain the bit field
+ for setting the bit to enable unaligned
+ access.
+
+DEVICE MODE
+===========
+ - reg : Four register ranges as listed in the reg-names property
+ - reg-names : "ti-conf" for the TI-specific registers
+ "ep_dbics" for the standard configuration registers as
+ they are locally accessed within the DIF CS space
+ "ep_dbics2" for the standard configuration registers as
+ they are locally accessed within the DIF CS2 space
+ "addr_space" used to map remote RC address space
+ - interrupts : one interrupt entries must be specified for main interrupt.
+ - num-ib-windows : number of inbound address translation windows
+ - num-ob-windows : number of outbound address translation windows
+ - ti,syscon-unaligned-access: phandle to the syscon DT node. The 1st argument
+ should contain the register offset within syscon
+ and the 2nd argument should contain the bit field
+ for setting the bit to enable unaligned
+ access.
+
+Optional Property:
+ - gpios : Should be added if a GPIO line is required to drive PERST# line
+
+NOTE: Two DT nodes may be added for each PCI controller; one for host
+mode and another for device mode. So in order for PCI to
+work in host mode, EP mode DT node should be disabled and in order to PCI to
+work in EP mode, host mode DT node should be disabled. Host mode and EP
+mode are mutually exclusive.

+V3 Semiconductor V360 EPC PCI bridge
+
+This bridge is found in the ARM Integrator/AP (Application Platform)
+
+Required properties:
+- compatible: should be one of:
+ "v3,v360epc-pci"
+ "arm,integrator-ap-pci", "v3,v360epc-pci"
+- reg: should contain two register areas:
+ first the base address of the V3 host bridge controller, 64KB
+ second the configuration area register space, 16MB
+- interrupts: should contain a reference to the V3 error interrupt
+ as routed on the system.
+- bus-range: see pci.txt
+- ranges: this follows the standard PCI bindings in the IEEE Std
+ 1275-1994 (see pci.txt) with the following restriction:
+ - The non-prefetchable and prefetchable memory windows must
+ each be exactly 256MB (0x10000000) in size.
+ - The prefetchable memory window must be immediately adjacent
+ to the non-prefetcable memory window
+- dma-ranges: three ranges for the inbound memory region. The ranges must
+ be aligned to a 1MB boundary, and may be 1MB, 2MB, 4MB, 8MB, 16MB, 32MB,
+ 64MB, 128MB, 256MB, 512MB, 1GB or 2GB in size. The memory should be marked
+ as pre-fetchable. Two ranges are supported by the hardware.
+
+Integrator-specific required properties:
+- syscon: should contain a link to the syscon device node, since
+ on the Integrator, some registers in the syscon are required to
+ operate the V3 host bridge.
+
+Example:

+- msi-controller: indicates that this is an X-Gene v1 PCIe MSI controller node
+- reg: physical base address (0x79000000) and length (0x900000) for controller
+ registers. These registers include the MSI termination address and data

+title: RISC-V SBI PMU events
+
+maintainers:

+
+description: |
+ The SBI PMU extension allows supervisor software to configure, start and
+ stop any performance counter at anytime. Thus, a user can leverage all
+ capabilities of performance analysis tools, such as perf, if the SBI PMU
+ extension is enabled. The following constraints apply:
+
+ The platform must provide information about PMU event to counter mappings
+ either via device tree or another way, specific to the platform.
+ Without the event to counter mappings, the SBI PMU extension cannot be used.
+
+ Platforms should provide information about the PMU event selector values
+ that should be encoded in the expected value of MHPMEVENTx while configuring
+ MHPMCOUNTERx for that specific event. The can either be done via device tree
+ or another way, specific to the platform.
+ The exact value to be written to MHPMEVENTx is completely dependent on the
+ platform.
+
+ For information on the SBI specification see the section "Performance
+ Monitoring Unit Extension" of:
+ https://github.com/riscv-non-isa/riscv-sbi-doc/blob/master/riscv-sbi.adoc

+* APM X-Gene 15Gbps Multi-purpose PHY nodes
+
+PHY nodes are defined to describe on-chip 15Gbps Multi-purpose PHY. Each
+PHY (pair of lanes) has its own node.
+
+Required properties:
+- compatible : Shall be "apm,xgene-phy".
+- reg : PHY memory resource is the SDS PHY access resource.
+- #phy-cells : Shall be 1 as it expects one argument for setting
+ the mode of the PHY. Possible values are 0 (SATA),
+ 1 (SGMII), 2 (PCIe), 3 (USB), and 4 (XFI).
+
+Optional properties:
+- status : Shall be "ok" if enabled or "disabled" if disabled.
+ Default is "ok".
+- clocks : Reference to the clock entry.
+- apm,tx-eye-tuning : Manual control to fine tune the capture of the serial
+ bit lines from the automatic calibrated position.
+ Two set of 3-tuple setting for each (up to 3)
+ supported link speed on the host. Range from 0 to
+ 127 in unit of one bit period. Default is 10.
+- apm,tx-eye-direction : Eye tuning manual control direction. 0 means sample
+ data earlier than the nominal sampling point. 1 means
+ sample data later than the nominal sampling point.
+ Two set of 3-tuple setting for each (up to 3)
+ supported link speed on the host. Default is 0.
+- apm,tx-boost-gain : Frequency boost AC (LSB 3-bit) and DC (2-bit)
+ gain control. Two set of 3-tuple setting for each
+ (up to 3) supported link speed on the host. Range is
+ between 0 to 31 in unit of dB. Default is 3.
+- apm,tx-amplitude : Amplitude control. Two set of 3-tuple setting for
+ each (up to 3) supported link speed on the host.
+ Range is between 0 to 199500 in unit of uV.
+ Default is 199500 uV.
+- apm,tx-pre-cursor1 : 1st pre-cursor emphasis taps control. Two set of
+ 3-tuple setting for each (up to 3) supported link
+ speed on the host. Range is 0 to 273000 in unit of
+ uV. Default is 0.
+- apm,tx-pre-cursor2 : 2st pre-cursor emphasis taps control. Two set of
+ 3-tuple setting for each (up to 3) supported link
+ speed on the host. Range is 0 to 127400 in unit uV.
+ Default is 0x0.
+- apm,tx-post-cursor : Post-cursor emphasis taps control. Two set of
+ 3-tuple setting for Gen1, Gen2, and Gen3. Range is
+ between 0 to 0x1f in unit of 18.2mV. Default is 0xf.
+- apm,tx-speed : Tx operating speed. One set of 3-tuple for each
+ supported link speed on the host.
+ 0 = 1-2Gbps
+ 1 = 2-4Gbps (1st tuple default)
+ 2 = 4-8Gbps
+ 3 = 8-15Gbps (2nd tuple default)
+ 4 = 2.5-4Gbps
+ 5 = 4-5Gbps
+ 6 = 5-6Gbps
+ 7 = 6-16Gbps (3rd tuple default)
+
+NOTE: PHY override parameters are board specific setting.
+
+Example:
+ phy1: phy@1f21a000 {
+ compatible = "apm,xgene-phy";
+ reg = <0x0 0x1f21a000 0x0 0x100>;
+ #phy-cells = <1>;
+ };
+
+ phy2: phy@1f22a000 {
+ compatible = "apm,xgene-phy";
+ reg = <0x0 0x1f22a000 0x0 0x100>;
+ #phy-cells = <1>;
+ };
+
+ phy3: phy@1f23a000 {
+ compatible = "apm,xgene-phy";
+ reg = <0x0 0x1f23a000 0x0 0x100>;
+ #phy-cells = <1>;

+
+maintainers:
+ - Liu Ying <victor.liu@nxp.com>
+
+description: |
+ The Mixel LVDS PHY IP block is found on Freescale i.MX8qm SoC.
+ It converts two groups of four 7/10 bits of CMOS data into two
+ groups of four data lanes of LVDS data streams. A phase-locked
+ transmit clock is transmitted in parallel with each group of
+ data streams over a fifth LVDS link. Every cycle of the transmit
+ clock, 56/80 bits of input data are sampled and transmitted
+ through the two groups of LVDS data streams. Together with the
+ transmit clocks, the two groups of LVDS data streams form two
+ LVDS channels.
+
+ The Mixel LVDS PHY found on Freescale i.MX8qm SoC is controlled
+ by Control and Status Registers(CSR) module in the SoC. The CSR
+ module, as a system controller, contains the PHY's registers.

+ Lan966x has 7 interfaces, consisting of 2 copper transceivers(CU),
+ 3 SERDES6G and 2 RGMII interfaces. Two of the SERDES6G support QSGMII.
+ Also it has 8 logical Ethernet ports which can be connected to these
+ interfaces. The Serdes controller will allow to configure these interfaces
+ and allows to "mux" the interfaces to different ports.
+
+ For simple selection of the interface that is used with a port, the
+ following macros are defined CU(X), SERDES6G(X), RGMII(X). Where X is a
+ number that represents the index of that interface type. For example
+ CU(1) means use interface copper transceivers 1. SERDES6G(2) means use
+ interface SerDes 2.

+
+description: |
+ On Microsemi Ocelot, there is a handful of registers in HSIO address
+ space for setting up the SerDes to switch port muxing.
+
+ A SerDes X can be "muxed" to work with switch port Y or Z for example.
+ One specific SerDes can also be used as a PCIe interface.
+
+ Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
+
+ There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
+ half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
+ 10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
+
+ Also, SERDES6G number (aka "macro") 0 is the only interface supporting
+ QSGMII.
+
+ This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
+ Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.

+title: NVIDIA Tegra124 XUSB pad controller
+
+maintainers:
+ - Thierry Reding <thierry.reding@gmail.com>
+ - Jon Hunter <jonathanh@nvidia.com>
+
+description: |
+ The Tegra XUSB pad controller manages a set of I/O lanes (with differential
+ signals) which connect directly to pins/pads on the SoC package. Each lane
+ is controlled by a HW block referred to as a "pad" in the Tegra hardware
+ documentation. Each such "pad" may control either one or multiple lanes,
+ and thus contains any logic common to all its lanes. Each lane can be
+ separately configured and powered up.
+
+ Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
+ super-speed USB. Other lanes are for various types of low-speed, full-speed
+ or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
+ contains a software-configurable mux that sits between the I/O controller
+ ports (e.g. PCIe) and the lanes.
+
+ In addition to per-lane configuration, USB 3.0 ports may require additional
+ settings on a per-board basis.
+
+ Pads will be represented as children of the top-level XUSB pad controller
+ device tree node. Each lane exposed by the pad will be represented by its
+ own subnode and can be referenced by users of the lane using the standard
+ PHY bindings, as described by the phy-bindings.txt file in this directory.
+
+ The Tegra hardware documentation refers to the connection between the XUSB
+ pad controller and the XUSB controller as "ports". This is confusing since
+ "port" is typically used to denote the physical USB receptacle. The device
+ tree binding in this document uses the term "port" to refer to the logical
+ abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+ for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+ USB 3.0 receptacles, ...).

+

+ - Jon Hunter <jonathanh@nvidia.com>
+
+description: |
+ The Tegra XUSB pad controller manages a set of I/O lanes (with differential
+ signals) which connect directly to pins/pads on the SoC package. Each lane
+ is controlled by a HW block referred to as a "pad" in the Tegra hardware
+ documentation. Each such "pad" may control either one or multiple lanes,
+ and thus contains any logic common to all its lanes. Each lane can be
+ separately configured and powered up.
+
+ Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
+ super-speed USB. Other lanes are for various types of low-speed, full-speed
+ or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
+ contains a software-configurable mux that sits between the I/O controller
+ ports (e.g. PCIe) and the lanes.
+
+ In addition to per-lane configuration, USB 3.0 ports may require additional
+ settings on a per-board basis.
+
+ Pads will be represented as children of the top-level XUSB pad controller
+ device tree node. Each lane exposed by the pad will be represented by its
+ own subnode and can be referenced by users of the lane using the standard
+ PHY bindings, as described by the phy-bindings.txt file in this directory.
+
+ The Tegra hardware documentation refers to the connection between the XUSB
+ pad controller and the XUSB controller as "ports". This is confusing since
+ "port" is typically used to denote the physical USB receptacle. The device
+ tree binding in this document uses the term "port" to refer to the logical
+ abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+ for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+ USB 3.0 receptacles, ...).

+ "port" is typically used to denote the physical USB receptacle. The device
+ tree binding in this document uses the term "port" to refer to the logical
+ abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+ for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+ USB 3.0 receptacles, ...).

+

+
+description: |
+ The Tegra XUSB pad controller manages a set of I/O lanes (with differential
+ signals) which connect directly to pins/pads on the SoC package. Each lane
+ is controlled by a HW block referred to as a "pad" in the Tegra hardware
+ documentation. Each such "pad" may control either one or multiple lanes,
+ and thus contains any logic common to all its lanes. Each lane can be
+ separately configured and powered up.
+
+ Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
+ super-speed USB. Other lanes are for various types of low-speed, full-speed
+ or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
+ contains a software-configurable mux that sits between the I/O controller
+ ports (e.g. PCIe) and the lanes.
+
+ In addition to per-lane configuration, USB 3.0 ports may require additional
+ settings on a per-board basis.
+
+ Pads will be represented as children of the top-level XUSB pad controller
+ device tree node. Each lane exposed by the pad will be represented by its
+ own subnode and can be referenced by users of the lane using the standard
+ PHY bindings, as described by the phy-bindings.txt file in this directory.
+
+ The Tegra hardware documentation refers to the connection between the XUSB
+ pad controller and the XUSB controller as "ports". This is confusing since
+ "port" is typically used to denote the physical USB receptacle. The device
+ tree binding in this document uses the term "port" to refer to the logical
+ abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+ for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+ USB 3.0 receptacles, ...).

+This document explains only the device tree data binding. For general
+information about PHY subsystem refer to Documentation/driver-api/phy/phy.rst
+
+PHY device node
+===============
+
+Required Properties:
+#phy-cells: Number of cells in a PHY specifier; The meaning of all those
+ cells is defined by the binding for the phy node. The PHY
+ provider can use the values in cells to find the appropriate
+ PHY.
+
+Optional Properties:
+phy-supply: Phandle to a regulator that provides power to the PHY. This
+ regulator will be managed during the PHY power on/off sequence.
+
+For example:
+
+phys: phy {
+ compatible = "xxx";
+ reg = <...>;
+ .
+ .
+ #phy-cells = <1>;
+ .
+ .
+};
+
+That node describes an IP block (PHY provider) that implements 2 different PHYs.
+In order to differentiate between these 2 PHYs, an additional specifier should be
+given while trying to get a reference to it.
+
+PHY user node
+=============
+
+Required Properties:
+phys : the phandle for the PHY device (used by the PHY subsystem; not to be
+ confused with the Ethernet specific 'phy' and 'phy-handle' properties,
+ see Documentation/devicetree/bindings/net/ethernet.txt for these)
+phy-names : the names of the PHY corresponding to the PHYs present in the
+ *phys* phandle
+
+Example 1:
+usb1: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&usb2_phy>, <&usb3_phy>;
+ phy-names = "usb2phy", "usb3phy";
+ .
+ .
+};
+
+This node represents a controller that uses two PHYs, one for usb2 and one for
+usb3.
+
+Example 2:
+usb2: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&phys 1>;
+ phy-names = "usbphy";
+ .
+ .
+};
+
+This node represents a controller that uses one of the PHYs of the PHY provider
+device defined previously. Note that the phy handle has an additional specifier
+"1" to differentiate between the two PHYs.

+STMicroelectronics STi MIPHY28LP PHY binding
+============================================
+
+This binding describes a miphy device that is used to control PHY hardware
+for SATA, PCIe or USB3.
+
+Required properties (controller (parent) node):
+- compatible : Should be "st,miphy28lp-phy".
+- st,syscfg : Should be a phandle of the system configuration register group
+ which contain the SATA, PCIe or USB3 mode setting bits.
+
+Required nodes : A sub-node is required for each channel the controller
+ provides. Address range information including the usual
+ 'reg' and 'reg-names' properties are used inside these
+ nodes to describe the controller's topology. These nodes
+ are translated by the driver's .xlate() function.
+
+Required properties (port (child) node):
+- #phy-cells : Should be 1 (See second example)
+ Cell after port phandle is device type from:
+ - PHY_TYPE_SATA
+ - PHY_TYPE_PCI
+ - PHY_TYPE_USB3
+- reg : Address and length of the register set for the device.
+- reg-names : The names of the register addresses corresponding to the registers
+ filled in "reg". It can also contain the offset of the system configuration
+ registers used as glue-logic to setup the device for SATA/PCIe or USB3
+ devices.
+- st,syscfg : Offset of the parent configuration register.
+- resets : phandle to the parent reset controller.
+- reset-names : Associated name must be "miphy-sw-rst".
+
+Optional properties (port (child) node):
+- st,osc-rdy : to check the MIPHY0_OSC_RDY status in the glue-logic. This
+ is not available in all the MiPHY. For example, for STiH407, only the
+ MiPHY0 has this bit.
+- st,osc-force-ext : to select the external oscillator. This can change from
+ different MiPHY inside the same SoC.
+- st,sata_gen : to select which SATA_SPDMODE has to be set in the SATA system config
+ register.
+- st,px_rx_pol_inv : to invert polarity of RXn/RXp (respectively negative line and positive
+ line).
+- st,scc-on : enable ssc to reduce effects of EMI (only for sata or PCIe).
+- st,tx-impedance-comp : to compensate tx impedance avoiding out of range values.
+
+example:
+
+ miphy28lp_phy: miphy28lp@9b22000 {
+ compatible = "st,miphy28lp-phy";

+Rockchip EMMC PHY
+-----------------------
+
+Required properties:
+ - compatible: rockchip,rk3399-emmc-phy
+ - #phy-cells: must be 0
+ - reg: PHY register address offset and length in "general
+ register files"
+
+Optional properties:
+ - clock-names: Should contain "emmcclk". Although this is listed as optional
+ (because most boards can get basic functionality without having
+ access to it), it is strongly suggested.
+ See ../clock/clock-bindings.txt for details.
+ - clocks: Should have a phandle to the card clock exported by the SDHCI driver.
+ - drive-impedance-ohm: Specifies the drive impedance in Ohm.
+ Possible values are 33, 40, 50, 66 and 100.
+ If not set, the default value of 50 will be applied.
+ - rockchip,enable-strobe-pulldown: Enable internal pull-down for the strobe
+ line. If not set, pull-down is not used.
+ - rockchip,output-tapdelay-select: Specifies the phyctrl_otapdlysec register.
+ If not set, the register defaults to 0x4.
+ Maximum value 0xf.
+
+Example:
+
+
+grf: syscon@ff770000 {
+ compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";

+Rockchip PCIE PHY
+-----------------------
+
+Required properties:
+ - compatible: rockchip,rk3399-pcie-phy
+ - clocks: Must contain an entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+ - clock-names: Must be "refclk"
+ - resets: Must contain an entry in reset-names.
+ See ../reset/reset.txt for details.
+ - reset-names: Must be "phy"
+
+Required properties for legacy PHY mode (deprecated):

+ For samsung,exynos5250-usbdrd-phy and samsung,exynos5420-usbdrd-phy

+ 0 - UTMI+ type phy,
+ 1 - PIPE3 type phy.
+
+ For SoCs like Exynos5420 having multiple USB 3.0 DRD PHY controllers,
+ 'usbdrd_phy' nodes should have numbered alias in the aliases node, in the

+Abilis Systems TB10x pin controller
+===================================
+
+Required properties
+-------------------
+
+- compatible: should be "abilis,tb10x-iomux";
+- reg: should contain the physical address and size of the pin controller's
+ register range.
+
+
+Function definitions
+--------------------
+
+Functions are defined (and referenced) by sub-nodes of the pin controller.
+Every sub-node defines exactly one function (implying a set of pins).
+Every function is associated to one named pin group inside the pin controller
+driver and these names are used to associate pin group predefinitions to pin
+controller sub-nodes.
+
+Required function definition subnode properties:
+ - abilis,function: should be set to the name of the function's pin group.
+
+The following pin groups are available:
+ - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
+ gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
+ - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
+ - Parallel TS input ports: mip1, mip3, mip5, mip7
+ - Serial TS output ports: mos0, mos1, mos2, mos3
+ - Parallel TS output port: mop
+ - CI+ port: ciplus
+ - CableCard (Mcard) port: mcard
+ - Smart card ports: stc0, stc1
+ - UART ports: uart0, uart1
+ - SPI ports: spi1, spi3
+ - JTAG: jtag
+
+All other ports of the chip are not multiplexed and thus not managed by this
+driver.
+
+
+GPIO ranges definition
+----------------------
+
+The named pin groups of GPIO ports can be used to define GPIO ranges as
+explained in Documentation/devicetree/bindings/gpio/gpio.txt.
+
+
+Example
+-------

+Actions Semi S700 Pin Controller
+
+This binding describes the pin controller found in the S700 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s700-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the pin controller
+- gpio-controller: Marks the device node as a GPIO controller.
+- gpio-ranges: Specifies the mapping between gpio controller and
+ pin-controller pins.
+- #gpio-cells: Should be two. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends
+ on the number of GPIO banks on the SoC. The interrupts must be
+ ordered by bank, starting with bank 0.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+Required Properties:

+* Atmel AT91 Pinmux Controller
+
+The AT91 Pinmux Controller, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called periph modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the controller controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Atmel AT91 pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'pins' selects the function mode(also named pin
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, multi drive, etc.
+
+Required properties for iomux controller:
+- compatible: "atmel,at91rm9200-pinctrl" or "atmel,at91sam9x5-pinctrl"
+ or "atmel,sama5d3-pinctrl" or "microchip,sam9x60-pinctrl"
+- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
+ configured in this periph mode. All the periph and bank need to be describe.
+
+How to create such array:
+
+Each column will represent the possible peripheral of the pinctrl
+Each line will represent a pio bank
+
+Take an example on the 9260
+Peripheral: 2 ( A and B)
+Bank: 3 (A, B and C)

+ /* A B */
+ 0xffffffff 0xffc00c3b /* pioA */
+ 0xffffffff 0x7fff3ccf /* pioB */
+ 0xffffffff 0x007fffff /* pioC */
+
+For each peripheral/bank we will describe in a u32 if a pin can be
+configured in it by putting 1 to the pin bit (1 << pin)
+
+Let's take the pioA on peripheral B
+From the datasheet Table 10-2.

+
+Required properties for pin configuration node:
+- atmel,pins: 4 integers array, represents a group of pins mux and config
+ setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
+ The PERIPH 0 means gpio, PERIPH 1 is periph A, PERIPH 2 is periph B...
+ PIN_BANK 0 is pioA, PIN_BANK 1 is pioB...
+
+Bits used for CONFIG:
+PULL_UP (1 << 0): indicate this pin needs a pull up.
+MULTIDRIVE (1 << 1): indicate this pin needs to be configured as multi-drive.
+ Multi-drive is equivalent to open-drain type output.
+DEGLITCH (1 << 2): indicate this pin needs deglitch.
+PULL_DOWN (1 << 3): indicate this pin needs a pull down.
+DIS_SCHMIT (1 << 4): indicate this pin needs to the disable schmitt trigger.
+DRIVE_STRENGTH (3 << 5): indicate the drive strength of the pin using the
+ following values:
+ 00 - No change (reset state value kept)
+ 01 - Low
+ 10 - Medium
+ 11 - High
+OUTPUT (1 << 7): indicate this pin need to be configured as an output.
+OUTPUT_VAL (1 << 8): output val (1 = high, 0 = low)
+SLEWRATE (1 << 9): slew rate of the pin: 0 = disable, 1 = enable
+DEBOUNCE (1 << 16): indicate this pin needs debounce.
+DEBOUNCE_VAL (0x3fff << 17): debounce value.
+
+NOTE:
+Some requirements for using atmel,at91rm9200-pinctrl binding:
+1. We have pin function node defined under at91 controller node to represent
+ what pinmux functions this SoC supports.
+2. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux at91 pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+3. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+4. The gpio controller must be describe in the pinctrl simple-bus.
+
+For each bank the required properties are:
+- compatible: "atmel,at91sam9x5-gpio" or "atmel,at91rm9200-gpio" or
+ "microchip,sam9x60-gpio"
+- reg: physical base address and length of the controller's registers
+- interrupts: interrupt outputs from the controller
+- interrupt-controller: marks the device node as an interrupt controller
+- #interrupt-cells: should be 2; refer to ../interrupt-controller/interrupts.txt
+ for more details.
+- gpio-controller
+- #gpio-cells: should be 2; the first cell is the GPIO number and the second
+ cell specifies GPIO flags as defined in <dt-bindings/gpio/gpio.h>.
+- clocks: bank clock

+Broadcom BCM2835 GPIO (and pinmux) controller
+
+The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
+controller, and pinmux/control device.
+
+Required properties:
+- compatible: "brcm,bcm2835-gpio"
+- compatible: should be one of:
+ "brcm,bcm2835-gpio" - BCM2835 compatible pinctrl
+ "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
+ "brcm,bcm2711-gpio" - BCM2711 compatible pinctrl
+ "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
+- reg: Should contain the physical address of the GPIO module's registers.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters:
+ - bit 0 specifies polarity (0 for normal, 1 for inverted)
+- interrupts : The interrupt outputs from the controller. One interrupt per
+ individual bank followed by the "all banks" interrupt. For BCM7211, an
+ additional set of per-bank interrupt line and an "all banks" wake-up
+ interrupt may be specified.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2.
+ The first cell is the GPIO number.
+ The second cell is used to specify flags:
+ bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 4 = active high level-sensitive.
+ 8 = active low level-sensitive.
+ Valid combinations are 1, 2, 3, 4, 8.
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux function to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pul parameter implies no information about the mux function.
+
+The BCM2835 pin configuration and multiplexing supports the generic bindings.
+For details on each properties, you can refer to ./pinctrl-bindings.txt.
+
+Required sub-node properties:
+ - pins
+ - function
+
+Optional sub-node properties:
+ - bias-disable
+ - bias-pull-up
+ - bias-pull-down
+ - output-high
+ - output-low
+
+Legacy pin configuration and multiplexing binding:
+*** (Its use is deprecated, use generic multiplexing and configuration
+bindings instead)
+
+Required subnode-properties:
+- brcm,pins: An array of cells. Each cell contains the ID of a pin. Valid IDs
+ are the integer GPIO IDs; 0==GPIO0, 1==GPIO1, ... 53==GPIO53.
+
+Optional subnode-properties:
+- brcm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alt5
+ 3: alt4
+ 4: alt0
+ 5: alt1
+ 6: alt2
+ 7: alt3
+- brcm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of brcm,function and brcm,pull may contain either a single value which
+will be applied to all pins in brcm,pins, or 1 value for each entry in
+brcm,pins.
+
+Example:
+
+ gpio: gpio {
+ compatible = "brcm,bcm2835-gpio";
+ reg = <0x2200000 0xb4>;
+ interrupts = <2 17>, <2 19>, <2 18>, <2 20>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;

+Broadcom iProc GPIO/PINCONF Controller
+
+Required properties:
+
+- compatible:
+ "brcm,iproc-gpio" for the generic iProc based GPIO controller IP that
+ supports full-featured pinctrl and GPIO functions used in various iProc
+ based SoCs
+
+ May contain an SoC-specific compatibility string to accommodate any
+ SoC-specific features
+
+ "brcm,cygnus-ccm-gpio", "brcm,cygnus-asiu-gpio", or
+ "brcm,cygnus-crmu-gpio" for Cygnus SoCs
+
+ "brcm,iproc-nsp-gpio" for the iProc NSP SoC that has drive strength support
+ disabled
+
+ "brcm,iproc-stingray-gpio" for the iProc Stingray SoC that has the general
+ pinctrl support completely disabled in this IP block. In Stingray, a
+ different IP block is used to handle pinctrl related functions
+
+- reg:
+ Define the base and range of the I/O address space that contains SoC
+GPIO/PINCONF controller registers
+
+- ngpios:
+ Total number of in-use slots in GPIO controller
+
+- #gpio-cells:
+ Must be two. The first cell is the GPIO pin number (within the
+controller's pin space) and the second cell is used for the following:
+ bit[0]: polarity (0 for active high and 1 for active low)
+
+- gpio-controller:
+ Specifies that the node is a GPIO controller
+
+Optional properties:
+
+- interrupts:
+ Interrupt ID
+
+- interrupt-controller:
+ Specifies that the node is an interrupt controller
+
+- gpio-ranges:
+ Specifies the mapping between gpio controller and pin-controllers pins.
+ This requires 4 fields in cells defined as -
+ 1. Phandle of pin-controller.
+ 2. GPIO base pin offset.
+ 3 Pin-control base pin offset.
+ 4. number of gpio pins which are linearly mapped from pin base.
+
+Supported generic PINCONF properties in child nodes:
+
+- pins:
+ The list of pins (within the controller's own pin space) that properties
+in the node apply to. Pin names are "gpio-<pin>"
+
+- bias-disable:
+ Disable pin bias
+
+- bias-pull-up:
+ Enable internal pull up resistor
+
+- bias-pull-down:
+ Enable internal pull down resistor
+
+- drive-strength:
+ Valid drive strength values include 2, 4, 6, 8, 10, 12, 14, 16 (mA)

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+ size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+ second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+ for possible values.
+
+For example, the following is the bare minimum node:
+
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+ configured by this node. The format of a pin name string is "GP_xy", where x
+ is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+ "gpio", "client_a", "client_b", "client_c"
+
+Example:
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+
+ uart0_default: uart0_active {
+ data_signals {
+ pins = "GP_O0", "GP_O1";
+ function = "client_b";
+ };
+ };
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ ...
+ pinctrl-0 = <&uart0_default>;
+ pinctrl-names = "default";
+ };
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Freescale IMX pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+ Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx*-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. And that's why fsl,pins entry
+ looks like <PIN_FUNC_ID CONFIG> in the example below.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+ what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+ to be defined under that specific function node.
+ The function node's name should represent well about what function
+ this group of pins in this pin configuration node are working on.
+3. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux IMX pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+4. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@219c000 { /* uSDHC4 */
+ non-removable;
+ vmmc-supply = <&reg_3p3v>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@20e0000 {
+ compatible = "fsl,imx6q-iomuxc";
+ reg = <0x020e0000 0x4000>;
+
+ /* shared pinctrl settings */
+ usdhc4 {
+ pinctrl_usdhc4_1: usdhc4grp-1 {
+ fsl,pins = <
+ MX6QDL_PAD_SD4_CMD__SD4_CMD 0x17059
+ MX6QDL_PAD_SD4_CLK__SD4_CLK 0x10059
+ MX6QDL_PAD_SD4_DAT0__SD4_DATA0 0x17059

+ MX6QDL_PAD_SD4_DAT7__SD4_DATA7 0x17059
+ >;
+ };
+ ....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.

+
+ PIN is an integer between 0 and 0xbf. imx27 has 6 ports with 32 configurable

+
+ direction defines the data direction of the pin.
+ Possible values:
+ 0 - Input
+ 1 - Output
+ Register: DDIR
+
+ gpio_oconf configures the gpio submodule output signal. This does not
+ have any effect unless GPIO function is selected. A/B/C_IN are output
+ signals of function blocks A,B and C. Specific function blocks are
+ described in the reference manual.
+ Possible values:
+ 0 - A_IN
+ 1 - B_IN
+ 2 - C_IN
+ 3 - Data Register
+ Registers: OCR1, OCR2
+
+ gpio_iconfa/b configures the gpio submodule input to functionblocks A and

+ Registers ICONFA1, ICONFA2, ICONFB1 and ICONFB2
+
+ CONFIG can be 0 or 1, meaning Pullup disable/enable.
+
+
+The iomux controller has gpio child nodes which are embedded in the iomux
+control registers. They have to be defined as child nodes of the iomux device
+node. If gpio subnodes are defined "#address-cells", "#size-cells" and "ranges"
+properties for the iomux device node are required.
+
+Example:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO. The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document. The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node. The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit. That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes. It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
+ with given mux function, with bank, pin and mux packed as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ This integer with mux selection packed is used as an entity by both group
+ and config nodes to identify a pin. The mux selection in the integer takes
+ effects only on group node, and will get ignored by driver with config node,
+ since config node is only meant to set up pin configurations.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function. This property
+ is required only for group nodes, and should not be present in any config
+ nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+ 0: MXS_DRIVE_4mA
+ 1: MXS_DRIVE_8mA
+ 2: MXS_DRIVE_12mA
+ 3: MXS_DRIVE_16mA
+- fsl,voltage: Integer.
+ 0: MXS_VOLTAGE_LOW - 1.8 V
+ 1: MXS_VOLTAGE_HIGH - 3.3 V
+- fsl,pull-up: Integer.
+ 0: MXS_PULL_DISABLE - Disable the internal pull-up
+ 1: MXS_PULL_ENABLE - Enable the internal pull-up
+
+Note that when enabling the pull-up, the internal pad keeper gets disabled.
+Also, some pins doesn't have a pull up, in that case, setting the fsl,pull-up
+will only disable the internal pad keeper.
+
+Examples:
+
+pinctrl@80018000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-pinctrl";
+ reg = <0x80018000 2000>;
+
+ mmc0_8bit_pins_a: mmc0-8bit@0 {
+ reg = <0>;
+ fsl,pinmux-ids = <
+ MX28_PAD_SSP0_DATA0__SSP0_D0
+ MX28_PAD_SSP0_DATA1__SSP0_D1
+ MX28_PAD_SSP0_DATA2__SSP0_D2
+ MX28_PAD_SSP0_DATA3__SSP0_D3
+ MX28_PAD_SSP0_DATA4__SSP0_D4
+ MX28_PAD_SSP0_DATA5__SSP0_D5
+ MX28_PAD_SSP0_DATA6__SSP0_D6
+ MX28_PAD_SSP0_DATA7__SSP0_D7
+ MX28_PAD_SSP0_CMD__SSP0_CMD
+ MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT
+ MX28_PAD_SSP0_SCK__SSP0_SCK
+ >;
+ fsl,drive-strength = <MXS_DRIVE_4mA>;
+ fsl,voltage = <MXS_VOLTAGE_HIGH>;
+ fsl,pull-up = <MXS_PULL_ENABLE>;
+ };
+
+ mmc_cd_cfg: mmc-cd-cfg {
+ fsl,pinmux-ids = <MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT>;
+ fsl,pull-up = <MXS_PULL_DISABLE>;
+ };
+
+ mmc_sck_cfg: mmc-sck-cfg {
+ fsl,pinmux-ids = <MX28_PAD_SSP0_SCK__SSP0_SCK>;
+ fsl,drive-strength = <MXS_DRIVE_12mA>;
+ fsl,pull-up = <MXS_PULL_DISABLE>;
+ };
+};
+
+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines. Only the configuration properties to be adjusted need
+to be listed in the config nodes.
+
+Valid values for i.MX28/i.MX23 pinmux-id are defined in
+arch/arm/boot/dts/imx28-pinfunc.h and arch/arm/boot/dts/imx23-pinfunc.h.
+The definitions for the padconfig properties can be found in
+arch/arm/boot/dts/mxs-pinfunc.h.

+Imagination Technologies Pistachio SoC pin controllers
+======================================================
+
+The pin controllers on Pistachio are a combined GPIO controller, (GPIO)
+interrupt controller, and pinmux + pinconf device. The system ("east") pin
+controller on Pistachio has 99 pins, 90 of which are MFIOs which can be
+configured as GPIOs. The 90 GPIOs are divided into 6 banks of up to 16 GPIOs
+each. The GPIO banks are represented as sub-nodes of the pad controller node.
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+Required properties for pin controller node:
+--------------------------------------------
+ - compatible: "img,pistachio-system-pinctrl".
+ - reg: Address range of the pinctrl registers.
+
+Required properties for GPIO bank sub-nodes:
+--------------------------------------------
+ - interrupts: Interrupt line for the GPIO bank.
+ - gpio-controller: Indicates the device is a GPIO controller.
+ - #gpio-cells: Must be two. The first cell is the GPIO pin number and the
+ second cell indicates the polarity. See <dt-bindings/gpio/gpio.h> for
+ a list of possible values.
+ - interrupt-controller: Indicates the device is an interrupt controller.
+ - #interrupt-cells: Must be two. The first cell is the GPIO pin number and
+ the second cell encodes the interrupt flags. See
+ <dt-bindings/interrupt-controller/irq.h> for a list of valid flags.
+
+Note that the N GPIO bank sub-nodes *must* be named gpio0, gpio1, ... gpioN-1.
+
+Required properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - pins: List of pins to which the configuration applies. See below for a
+ list of possible pins.

+description: >
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
+ may be used as GPIOs, multiplexed device functions are configured within the
+ GPIO port configuration registers and it is typical to refer to pins using the
+ naming scheme "PxN" where x is a character identifying the GPIO port with
+ which the pin is associated and N is an integer from 0 to 31 identifying the
+ pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
+ and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B,
+ the X1000 and the X1830 contains 4 GPIO ports, PA to PD, for a total of 128
+ pins. The X2000 and the X2100 contains 5 GPIO ports, PA to PE, for a total of
+ 160 pins. The JZ4750, the JZ4755 the JZ4760, the JZ4770 and the JZ4780 contains
+ 6 GPIO ports, PA to PF, for a total of 192 pins. The JZ4775 contains 7 GPIO
+ ports, PA to PG, for a total of 224 pins.

+Lantiq FALCON pinmux controller
+
+Required properties:
+- compatible: "lantiq,pinctrl-falcon"
+- reg: Should contain the physical address and length of the gpio/pinmux
+ register range
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Lantiq's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and two pin configuration parameters:
+pull-up and open-drain
+
+The name of each subnode is not important as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+We support 2 types of nodes.
+
+Definition of mux function groups:
+
+Required subnode-properties:
+- lantiq,groups : An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+- lantiq,function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+Valid values for group and function names:
+
+ mux groups:
+ por, ntr, ntr8k, hrst, mdio, bootled, asc0, spi, spi cs0, spi cs1, i2c,
+ jtag, slic, pcm, asc1
+
+ functions:
+ rst, ntr, mdio, led, asc, spi, i2c, jtag, slic, pcm
+
+
+Definition of pin configurations:
+
+Required subnode-properties:
+- lantiq,pins : An array of strings. Each string contains the name of a pin.
+ Valid values for these names are listed below.
+
+Optional subnode-properties:
+- lantiq,pull: Integer, representing the pull-down/up to apply to the pin.
+ 0: none, 1: down
+- lantiq,drive-current: Boolean, enables drive-current
+- lantiq,slew-rate: Boolean, enables slew-rate

+* Marvell Armada 37xx SoC pin and gpio controller
+
+Each Armada 37xx SoC come with two pin and gpio controller one for the
+south bridge and the other for the north bridge.
+
+Inside this set of register the gpio latch allows exposing some
+configuration of the SoC and especially the clock frequency of the
+xtal. Hence, this node is a represent as syscon allowing sharing the
+register between multiple hardware block.
+
+GPIO and pin controller:
+------------------------
+
+Main node:

+* Marvell SoC pinctrl core driver for mpp
+
+The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins
+(mpp) to a specific function. For each SoC family there is a SoC specific
+driver using this core driver.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+A Marvell SoC pin configuration node is a node of a group of pins which can
+be used for a specific device or function. Each node requires one or more
+mpp pins or group of pins and a mpp function common to all pins.
+
+Required properties for pinctrl driver:
+- compatible: "marvell,<soc>-pinctrl"
+ Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- marvell,pins: string array of mpp pins or group of pins to be muxed.
+- marvell,function: string representing a function to mux to for all
+ marvell,pins given in this pin configuration node. The function has to be
+ common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for
+ valid pin/pin group names and available function names for each SoC.
+
+Examples:
+
+uart1: serial@12100 {
+ compatible = "ns16550a";
+ reg = <0x12100 0x100>;
+ reg-shift = <2>;
+ interrupts = <7>;
+
+ pinctrl-0 = <&pmx_uart1_sw>;
+ pinctrl-names = "default";
+};
+
+pinctrl: pinctrl@d0200 {
+ compatible = "marvell,dove-pinctrl";
+ reg = <0xd0200 0x14>, <0xd0440 0x04>, <0xd802c 0x08>;
+
+ pmx_uart1_sw: pmx-uart1-sw {
+ marvell,pins = "mpp_uart1";
+ marvell,function = "uart1";
+ };
+};

+ DEPRECATED: Please use drive-strength-microamp instead.
+ Describe the specific driving setup property.
+ For I2C pins, the existing generic driving setup can only support
+ 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
+ can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+ driving setup, the existing generic setup will be disabled.
+ The specific driving setup is controlled by E1E0EN.
+ When E1=0/E0=0, the strength is 0.125mA.
+ When E1=0/E0=1, the strength is 0.25mA.
+ When E1=1/E0=0, the strength is 0.5mA.
+ When E1=1/E0=1, the strength is 1mA.
+ EN is used to enable or disable the specific driving setup.
+ Valid arguments are described as below:
+ 0: (E1, E0, EN) = (0, 0, 0)
+ 1: (E1, E0, EN) = (0, 0, 1)
+ 2: (E1, E0, EN) = (0, 1, 0)
+ 3: (E1, E0, EN) = (0, 1, 1)
+ 4: (E1, E0, EN) = (1, 0, 0)
+ 5: (E1, E0, EN) = (1, 0, 1)
+ 6: (E1, E0, EN) = (1, 1, 0)
+ 7: (E1, E0, EN) = (1, 1, 1)
+ So the valid arguments are from 0 to 7.

+ driving setup, the existing generic setup will be disabled.
+ The specific driving setup is controlled by E1E0EN.
+ When E1=0/E0=0, the strength is 0.125mA.
+ When E1=0/E0=1, the strength is 0.25mA.
+ When E1=1/E0=0, the strength is 0.5mA.
+ When E1=1/E0=1, the strength is 1mA.
+ EN is used to enable or disable the specific driving setup.
+ Valid arguments are described as below:
+ 0: (E1, E0, EN) = (0, 0, 0)

+* Microchip PIC32 Pin Controller
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+PIC32 'pin configuration node' is a node of a group of pins which can be
+used for a specific device or function. This node represents configurations of
+pins, optional function, and optional mux related configuration.
+
+Required properties for pin controller node:
+ - compatible: "microchip,pic32mada-pinctrl"
+ - reg: Address range of the pinctrl registers.
+ - clocks: Clock specifier (see clock bindings for details)
+
+Required properties for pin configuration sub-nodes:
+ - pins: List of pins to which the configuration applies.
+
+Optional properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - function: Mux function for the specified pins.
+ - bias-pull-up: Enable weak pull-up.
+ - bias-pull-down: Enable weak pull-down.
+ - input-enable: Set the pin as an input.
+ - output-low: Set the pin as an output level low.
+ - output-high: Set the pin as an output level high.
+ - microchip,digital: Enable digital I/O.
+ - microchip,analog: Enable analog I/O.

+Nuvoton NPCM7XX Pin Controllers
+
+The Nuvoton BMC NPCM7XX Pin Controller multi-function routed through
+the multiplexing block, Each pin supports GPIO functionality (GPIOx)
+and multiple functions that directly connect the pin to different
+hardware blocks.
+
+Required properties:
+- #address-cells : should be 1.
+- #size-cells : should be 1.
+- compatible : "nuvoton,npcm750-pinctrl" for Poleg NPCM7XX.
+- ranges : defines mapping ranges between pin controller node (parent)
+ to GPIO bank node (children).
+
+=== GPIO Bank Subnode ===
+
+The NPCM7XX has 8 GPIO Banks each GPIO bank supports 32 GPIO.
+
+Required GPIO Bank subnode-properties:
+- reg : specifies physical base address and size of the GPIO
+ bank registers.
+- gpio-controller : Marks the device node as a GPIO controller.
+- #gpio-cells : Must be <2>. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupts : contain the GPIO bank interrupt with flags for falling edge.
+- gpio-ranges : defines the range of pins managed by the GPIO bank controller.
+
+For example, GPIO bank subnodes like the following:
+ gpio0: gpio@f0010000 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x0 0x80>;
+ interrupts = <GIC_SPI 116 IRQ_TYPE_LEVEL_HIGH>;
+ gpio-ranges = <&pinctrl 0 0 32>;
+ };
+
+=== Pin Mux Subnode ===
+
+- pin: A string containing the name of the pin
+ An array of strings, each string containing the name of a pin.
+ These pin are used for selecting pin configuration.
+
+The following are the list of pins available:
+ "GPIO0/IOX1DI", "GPIO1/IOX1LD", "GPIO2/IOX1CK", "GPIO3/IOX1D0",

+For example, pinctrl might have pinmux subnodes like the following:
+
+ gpio0_iox1d1_pin: gpio0-iox1d1-pin {
+ pins = "GPIO0/IOX1DI";
+ output-high;
+ };
+ gpio0_iox1ck_pin: gpio0-iox1ck-pin {
+ pins = "GPIO2/IOX1CK";
+ output_high;
+ };
+
+=== Pin Group Subnode ===
+
+Required pin group subnode-properties:
+- groups : A string containing the name of the group to mux.
+- function: A string containing the name of the function to mux to the
+ group.
+
+The following are the list of the available groups and functions :
+ smb0, smb0b, smb0c, smb0d, smb0den, smb1, smb1b, smb1c, smb1d,
+ smb2, smb2b, smb2c, smb2d, smb3, smb3b, smb3c, smb3d, smb4, smb4b,

+ groups = "r1err";
+ function = "r1err";
+ };
+ r1md_pins: r1md-pins {

+description: |
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of
+ the phrase "pin configuration node".
+
+ Tegra's pin configuration nodes act as a container for an arbitrary number
+ of subnodes. Each of these subnodes represents some desired configuration
+ for a pin, a group, or a list of pins or groups. This configuration can
+ include the mux function to select on those pin(s)/ group(s), and various
+ pin configuration parameters, such as pull-up, tristate, drive strength,
+ etc.
+
+ The name of each subnode is not important; all subnodes should be
+ enumerated and processed purely based on their content.
+
+ Each subnode only affects those parameters that are explicitly listed. In
+ other words, a subnode that lists a mux function but no pin configuration
+ parameters implies no information about any pin configuration parameters.
+
+ Similarly, a pin subnode that describes a pullup parameter implies no
+ information about e.g. the mux function or tristate parameter. For this
+ reason, even seemingly boolean values are actually tristates in this
+ binding: unspecified, off, or on. Unspecified is represented as an absent
+ property, and off/on are represented as integer values 0 and 1.
+
+ Note that many of these properties are only valid for certain specific pins
+ or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+ details regarding which groups support which functionality. The Linux
+ pinctrl driver may also be a useful reference, since it consolidates,
+ disambiguates, and corrects data from all those sources.

+description: The Tegra124 pinctrl binding is very similar to the Tegra20 and
+ Tegra30 pinctrl binding, as described in nvidia,tegra20-pinmux.yaml and
+ nvidia,tegra30-pinmux.yaml. In fact, this document assumes that binding as a
+ baseline, and only documents the differences between the two bindings.

+Device tree binding for NVIDIA Tegra XUSB pad controller
+========================================================
+
+NOTE: It turns out that this binding isn't an accurate description of the XUSB
+pad controller. While the description is good enough for the functional subset
+required for PCIe and SATA, it lacks the flexibility to represent the features
+needed for USB. For the new binding, see ../phy/nvidia,tegra-xusb-padctl.txt.
+The binding described in this file is deprecated and should not be used.
+
+The Tegra XUSB pad controller manages a set of lanes, each of which can be
+assigned to one out of a set of different pads. Some of these pads have an
+associated PHY that must be powered up before the pad can be used.
+
+This document defines the device-specific binding for the XUSB pad controller.
+
+Refer to pinctrl-bindings.txt in this directory for generic information about
+pin controller device tree bindings and ../phy/phy-bindings.txt for details on
+how to describe and reference PHYs in device trees.
+
+Required properties:
+--------------------
+- compatible: For Tegra124, must contain "nvidia,tegra124-xusb-padctl".
+ Otherwise, must contain '"nvidia,<chip>-xusb-padctl",
+ "nvidia-tegra124-xusb-padctl"', where <chip> is tegra132 or tegra210.
+- reg: Physical base address and length of the controller's registers.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - padctl
+- #phy-cells: Should be 1. The specifier is the index of the PHY to reference.
+ See <dt-bindings/pinctrl/pinctrl-tegra-xusb.h> for the list of valid values.
+
+Lane muxing:
+------------
+
+Child nodes contain the pinmux configurations following the conventions from
+the pinctrl-bindings.txt document. Typically a single, static configuration is
+given and applied at boot time.
+
+Each subnode describes groups of lanes along with parameters and pads that
+they should be assigned to. The name of these subnodes is not important. All
+subnodes should be parsed solely based on their content.
+
+Each subnode only applies the parameters that are explicitly listed. In other
+words, if a subnode that lists a function but no pin configuration parameters
+implies no information about any pin configuration parameters. Similarly, a
+subnode that describes only an IDDQ parameter implies no information about
+what function the pins are assigned to. For this reason even seemingly boolean
+values are actually tristates in this binding: unspecified, off or on.
+Unspecified is represented as an absent property, and off/on are represented
+as integer values 0 and 1.
+
+Required properties:
+- nvidia,lanes: An array of strings. Each string is the name of a lane.
+
+Optional properties:
+- nvidia,function: A string that is the name of the function (pad) that the
+ pin or group should be assigned to. Valid values for function names are
+ listed below.
+- nvidia,iddq: Enables IDDQ mode of the lane. (0: no, 1: yes)
+
+Note that not all of these properties are valid for all lanes. Lanes can be
+divided into three groups:
+
+ - otg-0, otg-1, otg-2:
+
+ Valid functions for this group are: "snps", "xusb", "uart", "rsvd".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - ulpi-0, hsic-0, hsic-1:
+
+ Valid functions for this group are: "snps", "xusb".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - pcie-0, pcie-1, pcie-2, pcie-3, pcie-4, sata-0:
+
+ Valid functions for this group are: "pcie", "usb3", "sata", "rsvd".
+

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states that must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0: List of phandles, each pointing at a pin configuration
+ node. These referenced pin configuration nodes must be child
+ nodes of the pin controller that they configure. Multiple
+ entries may exist in this list so that multiple pin
+ controllers may be configured, or so that a state may be built
+ from multiple nodes for a single pin controller, each
+ contributing part of the overall configuration. See the next
+ section of this document for details of the format of these
+ pin configuration nodes.
+
+ In some cases, it may be useful to define a state, but for it
+ to be empty. This may be required when a common IP block is
+ used in an SoC either without a pin controller, or where the
+ pin controller does not affect the HW module in question. If
+ the binding for that IP block requires certain pin states to
+ exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+...
+pinctrl-n: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+pinctrl-names: The list of names to assign states. List entry 0 defines the
+ name for integer state ID 0, list entry 1 for state ID 1, and
+ so on.
+
+For example:
+
+ /* For a client device requiring named states */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a>, <&state_1_node_b>;
+ };
+
+ /* For the same device if using state IDs */
+ device {
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a>, <&state_1_node_b>;
+ };
+
+ /*
+ * For an IP block whose binding supports pin configuration,
+ * but in use on an SoC that doesn't have any pin control hardware
+ */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <>;
+ pinctrl-1 = <>;

+ - "mcp,mcp23s08" (DEPRECATED) for 8 GPIO SPI version
+ - "mcp,mcp23s17" (DEPRECATED) for 16 GPIO SPI version
+ - "mcp,mcp23008" (DEPRECATED) for 8 GPIO I2C version or
+ - "mcp,mcp23017" (DEPRECATED) for 16 GPIO I2C version of the chip
+
+ - "microchip,mcp23s08" for 8 GPIO SPI version
+ - "microchip,mcp23s17" for 16 GPIO SPI version
+ - "microchip,mcp23s18" for 16 GPIO SPI version
+ - "microchip,mcp23008" for 8 GPIO I2C version or
+ - "microchip,mcp23017" for 16 GPIO I2C version of the chip
+ - "microchip,mcp23018" for 16 GPIO I2C version
+ NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
+ removed.
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify flags as described in
+ 'Documentation/devicetree/bindings/gpio/gpio.txt'. Allowed values defined by
+ 'include/dt-bindings/gpio/gpio.h' (e.g. GPIO_ACTIVE_LOW).
+- gpio-controller : Marks the device node as a GPIO controller.
+- reg : For an address on its bus. I2C uses this a the I2C address of the chip.
+ SPI uses this to specify the chipselect line which the chip is
+ connected to. The driver and the SPI variant of the chip support
+ multiple chips on the same chipselect. Have a look at
+ microchip,spi-present-mask below.
+
+Required device specific properties (only for SPI chips):
+- mcp,spi-present-mask (DEPRECATED)
+- microchip,spi-present-mask : This is a present flag, that makes only sense for SPI
+ chips - as the name suggests. Multiple SPI chips can share the same
+ SPI chipselect. Set a bit in bit0-7 in this mask to 1 if there is a
+ chip connected with the corresponding spi address set. For example if
+ you have a chip with address 3 connected, you have to set bit3 to 1,
+ which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
+ possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
+ least one bit to 1 for SPI chips.
+ NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
+ removed.
+- spi-max-frequency = The maximum frequency this chip is able to handle
+
+Optional properties:
+- #interrupt-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify flags.
+- interrupt-controller: Marks the device node as a interrupt controller.
+- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
+ the IRQ output as open drain active low.
+- reset-gpios: Corresponds to the active-low RESET# pin for the chip
+
+Optional device specific properties:
+- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
+ with two interrupt outputs (these are the devices ending with 17 and
+ those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
+ IO 8-15 are bank 2. These chips have two different interrupt outputs:
+ One for bank 1 and another for bank 2. If irq-mirror is set, both
+ interrupts are generated regardless of the bank that an input change
+ occurred on. If it is not set, the interrupt are only generated for the
+ bank they belong to.
+ On devices with only one interrupt output this property is useless.
+- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
+ configures the IRQ output polarity as active high.
+
+Example I2C (with interrupt):
+gpiom1: gpio@20 {
+ compatible = "microchip,mcp23017";
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x20>;
+
+ interrupt-parent = <&gpio1>;
+ interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #interrupt-cells=<2>;
+ microchip,irq-mirror;
+};
+
+Example SPI:
+gpiom1: gpio@0 {
+ compatible = "microchip,mcp23s17";
+ gpio-controller;
+ #gpio-cells = <2>;
+ microchip,spi-present-mask = <0x01>;
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+};
+
+Pull-up configuration
+=====================
+
+If pins are used as output, they can also be configured with pull-ups. This is
+done with pinctrl.
+
+Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
+for details of the common pinctrl bindings used by client devices,
+including the meaning of the phrase "pin configuration node".
+
+Optional Pinmux properties:
+--------------------------
+Following properties are required if default setting of pins are required
+at boot.
+- pinctrl-names: A pinctrl state named per <pinctrl-bindings.txt>.
+- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
+ <pinctrl-bindings.txt>.
+
+The pin configurations are defined as child of the pinctrl states node. Each
+sub-node have following properties:
+
+Required properties:
+------------------
+- pins: List of pins. Valid values of pins properties are:
+ gpio0 ... gpio7 for the devices with 8 GPIO pins and
+ gpio0 ... gpio15 for the devices with 16 GPIO pins.
+
+Optional properties:
+-------------------
+The following optional property is defined in the pinmux DT binding document
+<pinctrl-bindings.txt>. Absence of this property will leave the configuration
+in its default state.
+ bias-pull-up
+
+Example with pinctrl to pull-up output pins:

+Palmas Pincontrol bindings
+
+The pins of Palmas device can be set on different option and provides
+the configuration for Pull UP/DOWN, open drain etc.
+
+Required properties:
+- compatible: It must be one of following:
+ - "ti,palmas-pinctrl" for Palma series of the pincontrol.
+ - "ti,tps65913-pinctrl" for Palma series device TPS65913.
+ - "ti,tps80036-pinctrl" for Palma series device TPS80036.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Palmas's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+list of pins. This configuration can include the mux function to select on
+those pin(s), and various pin configuration parameters, such as pull-up,
+open drain.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Optional properties:
+- ti,palmas-enable-dvfs1: Enable DVFS1. Configure pins for DVFS1 mode.
+ Selection primary or secondary function associated to I2C2_SCL_SCE,
+ I2C2_SDA_SDO pin/pad for DVFS1 interface
+- ti,palmas-enable-dvfs2: Enable DVFS2. Configure pins for DVFS2 mode.
+ Selection primary or secondary function associated to GPADC_START
+ and SYSEN2 pin/pad for DVFS2 interface
+- ti,palmas-override-powerhold: This is applicable for PMICs for which
+ GPIO7 is configured in POWERHOLD mode which has higher priority
+ over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON
+ bit is turned off. This property enables driver to over ride the
+ POWERHOLD value to GPIO7 so as to turn off the PMIC in power off
+ scenarios. So for GPIO7 if ti,palmas-override-powerhold is set
+ then the GPIO_7 field should never be muxed to anything else.
+ It should be set to POWERHOLD by default and only in case of
+ power off scenarios the driver will over ride the mux value.
+
+This binding uses the following generic properties as defined in
+pinctrl-bindings.txt:
+
+Required: pins
+Options: function, bias-disable, bias-pull-up, bias-pull-down,
+ drive-open-drain.
+
+Note that many of these properties are only valid for certain specific pins.
+See the Palmas device datasheet for complete details regarding which pins
+support which functionality.
+
+Valid values for pin names are:
+ gpio0, gpio1, gpio2, gpio3, gpio4, gpio5, gpio6, gpio7, gpio8, gpio9,
+ gpio10, gpio11, gpio12, gpio13, gpio14, gpio15, vac, powergood,
+ nreswarm, pwrdown, gpadc_start, reset_in, nsleep, enable1, enable2,
+ int.
+
+Valid value of function names are:
+ gpio, led, pwm, regen, sysen, clk32kgaudio, id, vbus_det, chrg_det,
+ vac, vacok, powergood, usb_psel, msecure, pwrhold, int, nreswarm,
+ simrsto, simrsti, low_vbat, wireless_chrg1, rcm, pwrdown, gpadc_start,
+ reset_in, nsleep, enable.
+
+There are 4 special functions: opt0, opt1, opt2 and opt3. If any of these
+functions is selected then directly pins register will be written with 0, 1, 2
+or 3 respectively if it is valid for that pins or list of pins.
+
+Example:
+ palmas: tps65913 {
+ ....
+ pinctrl {
+ compatible = "ti,tps65913-pinctrl";
+ ti,palmas-enable-dvfs1;
+ pinctrl-names = "default";

+*ST pin controller.
+
+Each multi-function pin is controlled, driven and routed through the
+PIO multiplexing block. Each pin supports GPIO functionality (ALT0)
+and multiple alternate functions(ALT1 - ALTx) that directly connect
+the pin to different hardware blocks.
+
+When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and
+Pull Up (PU) are driven by the related PIO block.
+
+ST pinctrl driver controls PIO multiplexing block and also interacts with
+gpio driver to configure a pin.
+
+GPIO bank can have one of the two possible types of interrupt-wirings.
+
+First type is via irqmux, single interrupt is used by multiple gpio banks. This
+reduces number of overall interrupts numbers required. All these banks belong to
+a single pincontroller.
+ _________
+ | |----> [gpio-bank (n) ]
+ | |----> [gpio-bank (n + 1)]
+ [irqN]-- | irq-mux |----> [gpio-bank (n + 2)]
+ | |----> [gpio-bank (... )]
+ |_________|----> [gpio-bank (n + 7)]
+
+Second type has a dedicated interrupt per gpio bank.
+
+ [irqN]----> [gpio-bank (n)]
+
+
+Pin controller node:
+Required properties:
+- compatible : should be "st,stih407-<pio-block>-pinctrl"
+- st,syscfg : Should be a phandle of the syscfg node.
+- st,retime-pin-mask : Should be mask to specify which pins can be retimed.
+ If the property is not present, it is assumed that all the pins in the
+ bank are capable of retiming. Retiming is mainly used to improve the
+ IO timing margins of external synchronous interfaces.
+- ranges : defines mapping between pin controller node (parent) to gpio-bank
+ node (children).
+
+Optional properties:
+- interrupts : Interrupt number of the irqmux. If the interrupt is shared
+ with other gpio banks via irqmux.
+ a irqline and gpio banks.
+- reg : irqmux memory resource. If irqmux is present.
+- reg-names : irqmux resource should be named as "irqmux".

+Required properties:
+- gpio-controller : Indicates this device is a GPIO controller
+- #gpio-cells : Must be two.

+ - Second cell: specifies whether the pin is logically inverted.
+ - 0 = active high

+- st,bank-name : Should be a name string for this bank as specified in
+ datasheet.
+
+Optional properties:
+- interrupts : Interrupt number for this gpio bank. If there is a dedicated
+ interrupt wired up for this gpio bank.
+
+- interrupt-controller : Indicates this device is a interrupt controller. GPIO
+ bank can be an interrupt controller iff one of the interrupt type either via
+irqmux or a dedicated interrupt per bank is specified.

+ gpio interrupt space of the controller.
+ - Second Cell: flags to identify the type of the interrupt
+ - 1 = rising edge triggered

+VIA VT8500 and Wondermedia WM8xxx-series pinmux/gpio controller
+
+These SoCs contain a combined Pinmux/GPIO module. Each pin may operate as
+either a GPIO in, GPIO out or as an alternate function (I2C, SPI etc).
+
+Required properties:
+- compatible: "via,vt8500-pinctrl", "wm,wm8505-pinctrl", "wm,wm8650-pinctrl",
+ "wm8750-pinctrl" or "wm,wm8850-pinctrl"
+- reg: Should contain the physical address of the module's registers.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters.
+ bit 0 - active low
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux functions to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pull parameter implies no information about the mux function.
+
+Required subnode-properties:
+- wm,pins: An array of cells. Each cell contains the ID of a pin.
+
+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alternate
+
+- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of wm,function and wm,pull may contain either a single value which
+will be applied to all pins in wm,pins, or one value for each entry in
+wm,pins.
+
+Example:
+
+ pinctrl: pinctrl {
+ compatible = "wm,wm8505-pinctrl";
+ reg = <0xD8110000 0x10000>;
+ interrupt-controller;

+SPEAr's pinmux nodes act as a container for an arbitrary number of subnodes. Each
+of these subnodes represents muxing for a pin, a group, or a list of pins or

+- st,function: A string containing the name of the function to mux to the pin or
+ group. See the SPEAr's TRM to determine which are valid for each pin or group.

+title: Generic Pin Multiplexing Node
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ The contents of the pin configuration child nodes are defined by the binding
+ for the individual pin controller device. The pin configuration nodes need not
+ be direct children of the pin controller device; they may be grandchildren,
+ for example. Whether this is legal, and whether there is any interaction
+ between the child and intermediate parent nodes, is again defined entirely by
+ the binding for the individual pin controller device.
+
+ While not required to be used, there are 3 generic forms of pin muxing nodes
+ which pin controller devices can use.
+
+ pin multiplexing nodes:
+
+ Example:
+
+ state_0_node_a {
+ uart0 {
+ function = "uart0";
+ groups = "u0rxtx", "u0rtscts";
+ };
+ };
+ state_1_node_a {
+ spi {
+ function = "spi0";
+ groups = "spi0pins";
+ };
+ };
+ state_2_node_a {
+ function = "i2c0";
+ pins = "mfio29", "mfio30";
+ };
+
+ Optionally an alternative binding can be used if more suitable depending on the
+ pin controller hardware. For hardware where there is a large number of identical
+ pin controller instances, naming each pin and function can easily become
+ unmaintainable. This is especially the case if the same controller is used for
+ different pins and functions depending on the SoC revision and packaging.
+
+ For cases like this, the pin controller driver may use pinctrl-pin-array helper
+ binding with a hardware based index and a number of pin configuration values:
+
+ pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+ #pinctrl-cells = <2>;
+
+ state_0_node_a {
+ pinctrl-pin-array = <
+ 0 A_DELAY_PS(0) G_DELAY_PS(120)
+ 4 A_DELAY_PS(0) G_DELAY_PS(360)
+ ...
+ >;
+ };
+ ...
+ };
+
+ Above #pinctrl-cells specifies the number of value cells in addition to the
+ index of the registers. This is similar to the interrupts-extended binding with
+ one exception. There is no need to specify the phandle for each entry as that
+ is already known as the defined pins are always children of the pin controller
+ node. Further having the phandle pointing to another pin controller would not
+ currently work as the pinctrl framework uses named modes to group pins for each
+ pin control device.
+
+ The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+ registers, and must not be a virtual index of pin instances. The reason for
+ this is to avoid mapping of the index in the dts files and the pin controller
+ driver as it can change.
+
+ For hardware where pin multiplexing configurations have to be specified for
+ each single pin the number of required sub-nodes containing "pin" and
+ "function" properties can quickly escalate and become hard to write and
+ maintain.
+
+ For cases like this, the pin controller driver may use the pinmux helper
+ property, where the pin identifier is provided with mux configuration settings
+ in a pinmux group. A pinmux group consists of the pin identifier and mux
+ settings represented as a single integer or an array of integers.
+
+ The pinmux property accepts an array of pinmux groups, each of them describing
+ a single pin multiplexing configuration.
+
+ pincontroller {
+ state_0_node_a {
+ pinmux = <PINMUX_GROUP>, <PINMUX_GROUP>, ...;
+ };
+ };
+
+ Each individual pin controller driver bindings documentation shall specify
+ how pin IDs and pin multiplexing configuration are defined and assembled
+ together in a pinmux group.

+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for pins are:
+ gpio0-gpio89
+
+Valid values for function are:
+ cam_mclk, codec_mic_i2s, codec_spkr_i2s, gp_clk_0a, gp_clk_0b, gp_clk_1a,
+ gp_clk_1b, gp_clk_2a, gp_clk_2b, gpio, gsbi1, gsbi2, gsbi3, gsbi4,
+ gsbi4_cam_i2c, gsbi5, gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6,
+ gsbi6_spi_cs1, gsbi6_spi_cs2, gsbi6_spi_cs3, gsbi7, gsbi7_spi_cs1,

+Qualcomm IPQ8064 TLMM block
+
+Required properties:
+- compatible: "qcom,ipq8064-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+- gpio-ranges: see ../gpio/gpio.txt
+
+Optional properties:
+
+- gpio-reserved-ranges: see ../gpio/gpio.txt
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for qcom,pins are:
+ gpio0-gpio68
+ Supports mux, bias, and drive-strength
+
+ sdc3_clk, sdc3_cmd, sdc3_data
+ Supports bias and drive-strength
+
+
+Valid values for function are:
+ mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gpio, gsbi1, gsbi2, gsbi4, gsbi5,
+ gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
+ spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
+ pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,
+ pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
+ pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
+ pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold
+
+Example:
+
+ pinmux: pinctrl@800000 {
+ compatible = "qcom,ipq8064-pinctrl";
+ reg = <0x800000 0x4000>;
+

+ A pin multiplexing sub-node describes how to configure a set of (or a
+ single) pin in some desired alternate function mode.
+ A single sub-node may define several pin configurations.
+ A few alternate function require special pin configuration flags to be
+ supplied along with the alternate function configuration number.
+ The hardware reference manual specifies when a pin function requires
+ "software IO driven" mode to be specified. To do so use the generic
+ properties from the <include/linux/pinctrl/pinconf_generic.h> header
+ file to instruct the pin controller to perform the desired pin
+ configuration operation.
+ The hardware reference manual specifies when a pin has to be configured
+ to work in bi-directional mode and when the IO direction has to be
+ specified by software. Bi-directional pins must be managed by the pin
+ controller driver internally, while software driven IO direction has to
+ be explicitly selected when multiple options are available.

+ When multiple pins are required to be configured as part of the
+ same alternate function they shall be specified as members of the
+ same argument list of a single "pinmux" property.
+ Helper macros to ease assembling the pin index from its position
+ (port where it sits on and pin number) and alternate function

+ The output pins(GTIOCxA and GTIOCxB) of the general PWM timer (GPT) can be
+ disabled by using the port output enabling function for the GPT (POEG).
+ Specifically, either of the following ways can be used.
+ * Input level detection of the GTETRGA to GTETRGD pins.
+ * Output-disable request from the GPT.
+ * SSF bit setting(ie, by setting POEGGn.SSF to 1)
+
+ The state of the GTIOCxA and the GTIOCxB pins when the output is disabled,

+
+description: |
+ The Rockchip Pinmux Controller enables the IC to share one PAD
+ to several functional blocks. The sharing is done by multiplexing
+ the PAD input/output signals. For each PAD there are several muxing
+ options with option 0 being used as a GPIO.
+
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ The Rockchip pin configuration node is a node of a group of pins which can be
+ used for a specific device or function. This node represents both mux and
+ config of the pins in that group. The 'pins' selects the function mode
+ (also named pin mode) this pin can work on and the 'config' configures
+ various pad settings such as pull-up, etc.
+
+ The pins are grouped into up to 9 individual pin banks which need to be
+ defined as gpio sub-nodes of the pinmux controller.

+* Spreadtrum Pin Controller
+
+The Spreadtrum pin controller are organized in 3 blocks (types).
+
+The first block comprises some global control registers, and each
+register contains several bit fields with one bit or several bits
+to configure for some global common configuration, such as domain
+pad driving level, system control select and so on ("domain pad
+driving level": One pin can output 3.0v or 1.8v, depending on the
+related domain pad driving selection, if the related domain pad
+select 3.0v, then the pin can output 3.0v. "system control" is used
+to choose one function (like: UART0) for which system, since we
+have several systems (AP/CP/CM4) on one SoC.).
+
+There are too much various configuration that we can not list all
+of them, so we can not make every Spreadtrum-special configuration
+as one generic configuration, and maybe it will add more strange
+global configuration in future. Then we add one "sprd,control" to
+set these various global control configuration, and we need use
+magic number for this property.
+
+Moreover we recognise every fields comprising one bit or several
+bits in one global control register as one pin, thus we should
+record every pin's bit offset, bit width and register offset to
+configure this field (pin).
+
+The second block comprises some common registers which have unified
+register definition, and each register described one pin is used
+to configure the pin sleep mode, function select and sleep related
+configuration.
+
+Now we have 4 systems for sleep mode on SC9860 SoC: AP system,
+PUBCP system, TGLDSP system and AGDSP system. And the pin sleep
+related configuration are:
+- input-enable
+- input-disable
+- output-high
+- output-low
+- bias-pull-up
+- bias-pull-down
+
+In some situation we need set the pin sleep mode and pin sleep related
+configuration, to set the pin sleep related configuration automatically
+by hardware when the system specified by sleep mode goes into deep
+sleep mode. For example, if we set the pin sleep mode as PUBCP_SLEEP
+and set the pin sleep related configuration as "input-enable", which
+means when PUBCP system goes into deep sleep mode, this pin will be set
+input enable automatically.
+
+Moreover we can not use the "sleep" state, since some systems (like:
+PUBCP system) do not run linux kernel OS (only AP system run linux
+kernel on SC9860 platform), then we can not select "sleep" state
+when the PUBCP system goes into deep sleep mode. Thus we introduce
+"sprd,sleep-mode" property to set pin sleep mode.
+
+The last block comprises some misc registers which also have unified
+register definition, and each register described one pin is used to
+configure drive strength, pull up/down and so on. Especially for pull
+up, we have two kind pull up resistor: 20K and 4.7K.
+
+Required properties for Spreadtrum pin controller:
+- compatible: "sprd,<soc>-pinctrl"
+ Please refer to each sprd,<soc>-pinctrl.txt binding doc for supported SoCs.
+- reg: The register address of pin controller device.
+- pins : An array of pin names.
+
+Optional properties:
+- function: Specified the function name.
+- drive-strength: Drive strength in mA.
+- input-schmitt-disable: Enable schmitt-trigger mode.
+- input-schmitt-enable: Disable schmitt-trigger mode.
+- bias-disable: Disable pin bias.
+- bias-pull-down: Pull down on pin.
+- bias-pull-up: Pull up on pin.
+- input-enable: Enable pin input.
+- input-disable: Enable pin output.
+- output-high: Set the pin as an output level high.
+- output-low: Set the pin as an output level low.
+- sleep-hardware-state: Indicate these configs in this state are sleep related.
+- sprd,control: Control values referring to databook for global control pins.
+- sprd,sleep-mode: Sleep mode selection.
+
+Please refer to each sprd,<soc>-pinctrl.txt binding doc for supported values.

+
+ The big MUX in the diagram only has 7 different ways of mapping peripherals
+ on the left to pins on the right. StarFive calls the 7 configurations "signal
+ groups".
+ However some peripherals have their I/O go through the 64 "GPIOs". The
+ diagram only shows UART0 and UART1, but this also includes a number of other
+ UARTs, I2Cs, SPIs, PWMs etc. All these peripherals are connected to all 64
+ GPIOs such that any GPIO can be set up to be controlled by any of the
+ peripherals.
+ Note that signal group 0 doesn't map any of the GPIOs to pins, and only
+ signal group 1 maps the GPIOs to the pins named PAD_GPIO[0] to PAD_GPIO[63].

+ST Ericsson Nomadik pinmux controller
+
+Required properties:
+- compatible: "stericsson,db8500-pinctrl", "stericsson,db8540-pinctrl",
+ "stericsson,stn8815-pinctrl"
+- nomadik-gpio-chips: array of phandles to the corresponding GPIO chips
+ (these have the register ranges used by the pin controller).
+- prcm: phandle to the PRCMU managing the back end of this pin controller
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as input, output, pull up, pull down...
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content. The subnodes use the generic
+pin multiplexing node layout from the standard pin control bindings
+(see pinctrl-bindings.txt):
+
+Required pin multiplexing subnode properties:
+- function: A string containing the name of the function to mux to the
+ pin or group.
+- groups : An array of strings. Each string contains the name of a pin
+ group that will be combined with the function to form a multiplexing
+ set-up.
+
+Required pin configuration subnode properties:
+- pins: A string array describing the pins affected by the configuration
+ in the node.
+- ste,config: Handle of pin configuration node
+ (e.g. ste,config = <&slpm_in_wkup_pdis>)
+
+- ste,input : <0/1/2>
+ 0: input with no pull
+ 1: input with pull up,
+ 2: input with pull down,
+
+- ste,output: <0/1/2>
+ 0: output low,
+ 1: output high,
+ 2: output (value is not specified).
+
+- ste,sleep: <0/1>
+ 0: sleep mode disable,
+ 1: sleep mode enable.
+
+- ste,sleep-input: <0/1/2/3>
+ 0: sleep input with no pull,
+ 1: sleep input with pull up,
+ 2: sleep input with pull down.
+ 3: sleep input and keep last input configuration (no pull, pull up or pull down).
+
+- ste,sleep-output: <0/1/2>
+ 0: sleep output low,
+ 1: sleep output high,
+ 2: sleep output (value is not specified).
+
+- ste,sleep-gpio: <0/1>
+ 0: disable sleep gpio mode,
+ 1: enable sleep gpio mode.
+
+- ste,sleep-wakeup: <0/1>
+ 0: wake-up detection enabled,
+ 1: wake-up detection disabled.
+
+- ste,sleep-pull-disable: <0/1>
+ 0: GPIO pull-up or pull-down resistor is enabled, when pin is an input,
+ 1: GPIO pull-up and pull-down resistor are disabled.

+
+description: |
+ The Sunplus SP7021 pin controller is used to control SoC pins. Please
+ refer to pinctrl-bindings.txt in this directory for details of the common
+ pinctrl bindings used by client devices.
+
+ SP7021 has 99 digital GPIO pins which are numbered from GPIO 0 to 98. All
+ are multiplexed with some special function pins. SP7021 has 3 types of
+ special function pins:
+
+ (1) function-group pins:
+ Ex 1 (SPI-NOR flash):
+ If control-field SPI_FLASH_SEL is set to 1, GPIO 83, 84, 86 and 87
+ will be pins of SPI-NOR flash. If it is set to 2, GPIO 76, 78, 79
+ and 81 will be pins of SPI-NOR flash.
+
+ Ex 2 (UART_0):
+ If control-bit UA0_SEL is set to 1, GPIO 88 and 89 will be TX and
+ RX pins of UART_0 (UART channel 0).
+
+ Ex 3 (eMMC):
+ If control-bit EMMC_SEL is set to 1, GPIO 72, 73, 74, 75, 76, 77,
+ 78, 79, 80, 81 will be pins of an eMMC device.
+
+ Properties "function" and "groups" are used to select function-group
+ pins.
+
+ (2) fully pin-mux (like phone exchange mux) pins:
+ GPIO 8 to 71 are 'fully pin-mux' pins. Any pins of peripherals of
+ SP7021 (ex: UART_1, UART_2, UART_3, UART_4, I2C_0, I2C_1, and etc.)
+ can be routed to any pins of fully pin-mux pins.
+
+ Ex 1 (UART channel 1):
+ If control-field UA1_TX_SEL is set to 3, TX pin of UART_1 will be
+ routed to GPIO 10 (3 - 1 + 8 = 10).
+ If control-field UA1_RX_SEL is set to 4, RX pin of UART_1 will be
+ routed to GPIO 11 (4 - 1 + 8 = 11).
+ If control-field UA1_RTS_SEL is set to 5, RTS pin of UART_1 will
+ be routed to GPIO 12 (5 - 1 + 8 = 12).
+ If control-field UA1_CTS_SEL is set to 6, CTS pin of UART_1 will
+ be routed to GPIO 13 (6 - 1 + 8 = 13).
+
+ Ex 2 (I2C channel 0):
+ If control-field I2C0_CLK_SEL is set to 20, CLK pin of I2C_0 will
+ be routed to GPIO 27 (20 - 1 + 8 = 27).
+ If control-field I2C0_DATA_SEL is set to 21, DATA pin of I2C_0
+ will be routed to GPIO 28 (21 - 1 + 9 = 28).
+
+ Totally, SP7021 has 120 peripheral pins. The peripheral pins can be
+ routed to any of 64 'fully pin-mux' pins.
+
+ (3) I/O processor pins
+ SP7021 has a built-in I/O processor.
+ Any GPIO pins (GPIO 0 to 98) can be set to pins of I/O processor.
+
+ Vendor property "sunplus,pins" is used to select "fully pin-mux" pins,
+ "I/O processor pins" and "digital GPIO" pins.
+
+ The device node of pin controller of Sunplus SP7021 has following
+ properties.

+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ Zynq's pin configuration nodes act as a container for an arbitrary number of
+ subnodes. Each of these subnodes represents some desired configuration for a
+ pin, a group, or a list of pins or groups. This configuration can include the
+ mux function to select on those pin(s)/group(s), and various pin configuration
+ parameters, such as pull-up, slew rate, etc.
+
+ Each configuration node can consist of multiple nodes describing the pinmux and
+ pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
+
+ The name of each subnode is not important; all subnodes should be enumerated
+ and processed purely based on their content.

+Device-tree bindings for persistent memory regions
+-----------------------------------------------------
+
+Persistent memory refers to a class of memory devices that are:
+
+ a) Usable as main system memory (i.e. cacheable), and
+ b) Retain their contents across power failure.
+
+Given b) it is best to think of persistent memory as a kind of memory mapped
+storage device. To ensure data integrity the operating system needs to manage
+persistent regions separately to the normal memory pool. To aid with that this
+binding provides a standardised interface for discovering where persistent
+memory regions exist inside the physical address space.
+
+Bindings for the region nodes:
+-----------------------------
+
+Required properties:
+ - compatible = "pmem-region"
+
+ - reg = <base, size>;
+ The reg property should specify an address range that is
+ translatable to a system physical address range. This address
+ range should be mappable as normal system memory would be
+ (i.e cacheable).
+
+ If the reg property contains multiple address ranges
+ each address range will be treated as though it was specified
+ in a separate device node. Having multiple address ranges in a
+ node implies no special relationship between the two ranges.
+
+Optional properties:
+ - Any relevant NUMA associativity properties for the target platform.
+
+ - volatile; This property indicates that this region is actually
+ backed by non-persistent memory. This lets the OS know that it
+ may skip the cache flushes required to ensure data is made
+ persistent after a write.
+
+ If this property is absent then the OS must assume that the region
+ is backed by non-volatile memory.
+
+Examples:
+--------------------
+
+ /*
+ * This node specifies one 4KB region spanning from
+ * 0x5000 to 0x5fff that is backed by non-volatile memory.
+ */
+ pmem@5000 {
+ compatible = "pmem-region";
+ reg = <0x00005000 0x00001000>;
+ };
+
+ /*
+ * This node specifies two 4KB regions that are backed by
+ * volatile (normal) memory.
+ */
+ pmem@6000 {
+ compatible = "pmem-region";
+ reg = < 0x00006000 0x00001000
+ 0x00008000 0x00001000 >;
+ volatile;
+ };

+Amlogic Meson Power Controller (deprecated)
+===========================================
+
+The Amlogic Meson SoCs embeds an internal Power domain controller.
+
+VPU Power Domain
+----------------
+
+The Video Processing Unit power domain is controlled by this power controller,
+but the domain requires some external resources to meet the correct power
+sequences.
+The bindings must respect the power domain bindings as described in the file
+power-domain.yaml
+
+Device Tree Bindings:
+---------------------
+
+Required properties:
+- compatible: should be one of the following :
+ - "amlogic,meson-gx-pwrc-vpu" for the Meson GX SoCs
+ - "amlogic,meson-g12a-pwrc-vpu" for the Meson G12A SoCs
+- #power-domain-cells: should be 0
+- amlogic,hhi-sysctrl: phandle to the HHI sysctrl node
+- resets: phandles to the reset lines needed for this power demain sequence
+ as described in ../reset/reset.txt
+- clocks: from common clock binding: handle to VPU and VAPB clocks
+- clock-names: from common clock binding: must contain "vpu", "vapb"
+ corresponding to entry in the clocks property.
+
+Parent node should have the following properties :
+- compatible: "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"
+- reg: base address and size of the AO system control register space.
+
+Example:
+-------
+
+ao_sysctrl: sys-ctrl@0 {
+ compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd";
+ reg = <0x0 0x0 0x0 0x100>;
+
+ pwrc_vpu: power-controller-vpu {

+description: |
+ CPR (Core Power Reduction) is a technology to reduce core power on a CPU
+ or other device. Each OPP of a device corresponds to a "corner" that has
+ a range of valid voltages for a particular frequency. While the device is
+ running at a particular frequency, CPR monitors dynamic factors such as
+ temperature, etc. and suggests adjustments to the voltage to save power
+ and meet silicon characteristic requirements.

+* Generic system power control capability
+
+Power-management integrated circuits or miscellaneous hardware components are
+sometimes able to control the system power. The device driver associated with these
+components might need to define this capability, which tells the kernel that
+it can be used to switch off the system. The corresponding device must have the
+standard property "system-power-controller" in its device node. This property
+marks the device as able to control the system power. In order to test if this
+property is found programmatically, use the helper function
+"of_device_is_system_power_controller" from of.h .

+* Generic PM domains
+
+System on chip designs are often divided into multiple PM domains that can be
+used for power gating of selected IP blocks for power saving by reduced leakage
+current.
+
+This device tree binding can be used to bind PM domain consumer devices with
+their PM domains provided by PM domain providers. A PM domain provider can be
+represented by any node in the device tree and can provide one or more PM
+domains. A consumer node can refer to the provider by a phandle and a set of
+phandle arguments (so called PM domain specifiers) of length specified by the
+#power-domain-cells property in the PM domain provider node.
+
+==PM domain providers==
+
+See power-domain.yaml.
+
+==PM domain consumers==
+
+Required properties:
+ - power-domains : A list of PM domain specifiers, as defined by bindings of
+ the power controller that is the PM domain provider.
+
+Optional properties:
+ - power-domain-names : A list of power domain name strings sorted in the same
+ order as the power-domains property. Consumers drivers will use
+ power-domain-names to match power domains with power-domains
+ specifiers.
+
+Example:
+
+ leaky-device@12350000 {
+ compatible = "foo,i-leak-current";
+ reg = <0x12350000 0x1000>;
+ power-domains = <&power 0>;
+ power-domain-names = "io";
+ };
+
+ leaky-device@12351000 {

+ reg = <0x12351000 0x1000>;
+ power-domains = <&power 0>, <&power 1> ;
+ power-domain-names = "io", "clk";
+ };
+
+The first example above defines a typical PM domain consumer device, which is
+located inside a PM domain with index 0 of a power controller represented by a
+node with the label "power".
+In the second example the consumer device are partitioned across two PM domains,
+the first with index 0 and the second with index 1, of a power controller that
+is represented by a node with the label "power".
+
+Optional properties:
+- required-opps: This contains phandle to an OPP node in another device's OPP
+ table. It may contain an array of phandles, where each phandle points to an
+ OPP of a different device. It should not contain multiple phandles to the OPP
+ nodes in the same OPP table. This specifies the minimum required OPP of the
+ device(s), whose OPP's phandle is present in this property, for the
+ functioning of the current device at the current OPP (where this property is
+ present).
+
+Example:

+ Drive a GPIO line that can be used to restart the system from a restart handler.
+
+ This binding supports level and edge triggered reset. At driver load time, the driver will
+ request the given gpio line and install a restart handler. If the optional properties
+ 'open-source' is not found, the GPIO line will be driven in the inactive state. Otherwise its
+ not driven until the restart is initiated.
+
+ When the system is restarted, the restart handler will be invoked in priority order. The GPIO
+ is configured as an output, and driven active, triggering a level triggered reset condition.
+ This will also cause an inactive->active edge condition, triggering positive edge triggered
+ reset. After a delay specified by active-delay, the GPIO is set to inactive, thus causing an
+ active->inactive edge, triggering negative edge triggered reset. After a delay specified by
+ inactive-delay, the GPIO is driven active again. After a delay specified by wait-delay, the
+ restart handler completes allowing other restart handlers to be attempted.

+* Device tree bindings for Texas Instruments keystone reset
+
+This node is intended to allow SoC reset in case of software reset
+of selected watchdogs.
+
+The Keystone SoCs can contain up to 4 watchdog timers to reset
+SoC. Each watchdog timer event input is connected to the Reset Mux
+block. The Reset Mux block can be configured to cause reset or not.
+
+Additionally soft or hard reset can be configured.
+
+Required properties:
+
+- compatible: ti,keystone-reset
+
+- ti,syscon-pll: phandle/offset pair. The phandle to syscon used to
+ access pll controller registers and the offset to use
+ reset control registers.
+
+- ti,syscon-dev: phandle/offset pair. The phandle to syscon used to
+ access device state control registers and the offset
+ in order to use mux block registers for all watchdogs.
+
+Optional properties:
+
+- ti,soft-reset: Boolean option indicating soft reset.
+ By default hard reset is used.
+
+- ti,wdt-list: WDT list that can cause SoC reset. It's not related
+ to WDT driver, it's just needed to enable a SoC related
+ reset that's triggered by one of WDTs. The list is
+ in format: <0>, <2>; It can be in random order and
+ begins from 0 to 3, as keystone can contain up to 4 SoC
+ reset watchdogs and can be in random order.
+
+Example 1:
+Setup keystone reset so that in case software reset or
+WDT0 is triggered it issues hard reset for SoC.
+
+pllctrl: pll-controller@2310000 {
+ compatible = "ti,keystone-pllctrl", "syscon";
+ reg = <0x02310000 0x200>;

+title: Rockchip SRAM for IO Voltage Domains
+
+maintainers:
+ - Heiko Stuebner <heiko@sntech.de>
+
+description: |
+ IO domain voltages on some Rockchip SoCs are variable but need to be
+ kept in sync between the regulators and the SoC using a special
+ register.
+
+ A specific example using rk3288
+ If the regulator hooked up to a pin like SDMMC0_VDD is 3.3V then
+ bit 7 of GRF_IO_VSEL needs to be 0. If the regulator hooked up to
+ that same pin is 1.8V then bit 7 of GRF_IO_VSEL needs to be 1.
+
+ Said another way, this driver simply handles keeping bits in the SoCs
+ General Register File (GRF) in sync with the actual value of a voltage
+ hooked up to the pins.
+
+ Note that this driver specifically does not include
+ any logic for deciding what voltage we should set regulators to
+ any logic for deciding whether regulators (or internal SoC blocks)
+ should have power or not have power
+
+ If there were some other software that had the smarts of making
+ decisions about regulators, it would work in conjunction with this
+ driver. When that other software adjusted a regulators voltage then
+ this driver would handle telling the SoC about it. A good example is
+ vqmmc for SD. In that case the dw_mmc driver simply is told about a
+ regulator. It changes the regulator between 3.3V and 1.8V at the
+ right time. This driver notices the change and makes sure that the
+ SoC is on the same page.
+
+ You specify supplies using the standard regulator bindings by including
+ a phandle the relevant regulator. All specified supplies must be able
+ to report their voltage. The IO Voltage Domain for any non-specified
+ supplies will be not be touched.

+
+description: |
+ The devicetree battery node provides static battery characteristics.
+ In smart batteries, these are typically stored in non-volatile memory
+ on a fuel gauge chip. The battery node should be used where there is
+ no appropriate non-volatile memory, or it is unprogrammed/incorrect.
+
+ Upstream dts files should not include battery nodes, unless the battery
+ represented cannot easily be replaced in the system by one of a
+ different type. This prevents unpredictable, potentially harmful,
+ behavior should a replacement that changes the battery type occur
+ without a corresponding update to the dtb.
+
+ Battery properties are named, where possible, for the corresponding elements
+ in enum power_supply_property, defined in include/linux/power_supply.h
+
+ Batteries must be referenced by chargers and/or fuel-gauges using a phandle.
+ The phandle's property should be named "monitored-battery".

+ After the hardware of MT6370 completes the BC1.2 detection,

+ Samsung SDI (Samsung Digital Interface) batteries are all different versions
+ of lithium ion chemistry devices used for mobile phones, laptops and other
+ portable electronics. The batteries are adapted to a specific product and
+ the physical restrictions make it impossible to use another battery with the
+ product, so product device trees can specify these batteries. Operating
+ systems should determine hardware characteristics of the batteries from the

+ A boolean value indicating thermistor interface to battery
+
+ Note:
+ 'btemp' and 'batctrl' are the pins interfaced for battery temperature

+ The battery charger needs to interact with the USB phy in order to know when
+ charging is permissible, and when there is a connection or disconnection.
+
+ The choice of phy cannot be configured at a hardware level, so there is no
+ value in explicit configuration in device-tree. Rather if there is a sibling
+ of the BCI node which is compatible with "ti,twl4030-usb", then that is used
+ to determine when and how use USB power for charging.

+Specifying wakeup capability for devices
+============================================
+
+Any device nodes
+----------------
+Nodes that describe devices which has wakeup capability must contain an
+"wakeup-source" boolean property.
+
+Also, if device is marked as a wakeup source, then all the primary
+interrupt(s) can be used as wakeup interrupt(s).
+
+However if the devices have dedicated interrupt as the wakeup source
+then they need to specify/identify the same using device specific
+interrupt name. In such cases only that interrupt can be used as wakeup
+interrupt.

+ Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
+ ID/CoreNet Snoop ID to cpu mapping functions. Certain bits from
+ these registers should be set if the corresponding CPU should be

+DMA driver, such as the SSI sound drivers for the MPC8610. Therefore, any DMA
+channel that should be used for another driver should not use
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel". For the SSI drivers, for
+example, the compatible property should be "fsl,ssi-dma-channel". See ssi.txt

+Interlaken Look-Aside Controller (LAC) Node
+
+DESCRIPTION
+
+The Interlaken is a narrow, high speed channelized chip-to-chip interface. To
+facilitate interoperability between a data path device and a look-aside
+co-processor, the Interlaken Look-Aside protocol is defined for short
+transaction-related transfers. Although based on the Interlaken protocol,
+Interlaken Look-Aside is not directly compatible with Interlaken and can be
+considered a different operation mode.
+
+The Interlaken LA controller connects internal platform to Interlaken serial
+interface. It accepts LA command through software portals, which are system
+memory mapped 4KB spaces. The LA commands are then translated into the
+Interlaken control words and data words, which are sent on TX side to TCAM
+through SerDes lanes.
+
+There are two 4KiB spaces defined within the LAC global register memory map.
+There is a full register set at 0x0000-0x0FFF (also known as the "hypervisor"
+version), and a subset at 0x1000-0x1FFF. The former is a superset of the
+latter, and includes certain registers that should not be accessible to
+partitioned software. Separate nodes are used for each region, with a phandle
+linking the hypervisor node to the normal operating node.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,interlaken-lac". This represents only
+ those LAC CCSR registers not protected in partitioned
+ software. The version of the device is determined by the LAC

+
+ Table of correspondences between IPBRR0 values and example
+ chips:
+ Value Device
+ ----------- -------
+ 0x02000100 T4240
+
+ The Hypervisor node has a different compatible. It must include
+ "fsl,interlaken-lac-hv". This node represents the protected
+ LAC register space and is required except inside a partition
+ where access to the hypervisor node is to be denied.

+DESCRIPTION
+The Interlaken Look-Aside Controller (LAC) utilizes Software Portals to accept
+Interlaken Look-Aside (ILA) commands. The Interlaken LAC software portal
+memory map occupies 128KB of memory space. The software portal memory space is
+intended to be cache-enabled. WIMG for each software space is required to be
+0010 if stashing is enabled; otherwise, WIMG can be 0000 or 0010.

+MPC5121 PSC Device Tree Bindings
+
+PSC in UART mode
+----------------
+
+For PSC in UART mode the needed PSC serial devices
+are specified by fsl,mpc5121-psc-uart nodes in the
+fsl,mpc5121-immr SoC node. Additionally the PSC FIFO
+Controller node fsl,mpc5121-psc-fifo is required there:
+
+fsl,mpc512x-psc-uart nodes
+--------------------------
+
+Required properties :
+ - compatible : Should contain "fsl,<soc>-psc-uart" and "fsl,<soc>-psc"
+ Supported <soc>s: mpc5121, mpc5125
+ - reg : Offset and length of the register set for the PSC device
+ - interrupts : <a b> where a is the interrupt number of the
+ PSC FIFO Controller and b is a field that represents an
+ encoding of the sense and level information for the interrupt.
+
+Recommended properties :
+ - fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
+ - fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)
+
+PSC in SPI mode
+---------------
+
+Similar to the UART mode a PSC can be operated in SPI mode. The compatible used
+for that is fsl,mpc5121-psc-spi. It requires a fsl,mpc5121-psc-fifo as well.
+The required and recommended properties are identical to the
+fsl,mpc5121-psc-uart nodes, just use spi instead of uart in the compatible
+string.
+
+fsl,mpc512x-psc-fifo node
+-------------------------
+
+Required properties :
+ - compatible : Should be "fsl,<soc>-psc-fifo"
+ Supported <soc>s: mpc5121, mpc5125
+ - reg : Offset and length of the register set for the PSC
+ FIFO Controller
+ - interrupts : <a b> where a is the interrupt number of the
+ PSC FIFO Controller and b is a field that represents an
+ encoding of the sense and level information for the interrupt.
+
+Recommended properties :
+ - clocks : specifies the clock needed to operate the fifo controller
+ - clock-names : name(s) for the clock(s) listed in clocks
+
+Example for a board using PSC0 and PSC1 devices in serial mode:
+

+MPC5200 Device Tree Bindings
+----------------------------
+
+(c) 2006-2009 Secret Lab Technologies Ltd
+Grant Likely <grant.likely@secretlab.ca>
+
+Naming conventions
+------------------
+For mpc5200 on-chip devices, the format for each compatible value is
+<chip>-<device>[-<mode>]. The OS should be able to match a device driver
+to the device based solely on the compatible value. If two drivers
+match on the compatible list; the 'most compatible' driver should be
+selected.
+
+The split between the MPC5200 and the MPC5200B leaves a bit of a
+conundrum. How should the compatible property be set up to provide
+maximum compatibility information; but still accurately describe the
+chip? For the MPC5200; the answer is easy. Most of the SoC devices
+originally appeared on the MPC5200. Since they didn't exist anywhere
+else; the 5200 compatible properties will contain only one item;
+"fsl,mpc5200-<device>".
+
+The 5200B is almost the same as the 5200, but not quite. It fixes
+silicon bugs and it adds a small number of enhancements. Most of the
+devices either provide exactly the same interface as on the 5200. A few
+devices have extra functions but still have a backwards compatible mode.
+To express this information as completely as possible, 5200B device trees
+should have two items in the compatible list:
+ compatible = "fsl,mpc5200b-<device>","fsl,mpc5200-<device>";
+
+It is *strongly* recommended that 5200B device trees follow this convention
+(instead of only listing the base mpc5200 item).
+
+ie. ethernet on mpc5200: compatible = "fsl,mpc5200-fec";
+ ethernet on mpc5200b: compatible = "fsl,mpc5200b-fec", "fsl,mpc5200-fec";
+
+Modal devices, like PSCs, also append the configured function to the
+end of the compatible field. ie. A PSC in i2s mode would specify
+"fsl,mpc5200-psc-i2s", not "fsl,mpc5200-i2s". This convention is chosen to
+avoid naming conflicts with non-psc devices providing the same
+function. For example, "fsl,mpc5200-spi" and "fsl,mpc5200-psc-spi" describe
+the mpc5200 simple spi device and a PSC spi mode respectively.
+
+At the time of writing, exact chip may be either 'fsl,mpc5200' or
+'fsl,mpc5200b'.
+
+The soc node
+------------
+This node describes the on chip SOC peripherals. Every mpc5200 based
+board will have this node, and as such there is a common naming
+convention for SOC devices.
+
+Required properties:
+name description
+---- -----------
+ranges Memory range of the internal memory mapped registers.
+ Should be <0 [baseaddr] 0xc000>
+reg Should be <[baseaddr] 0x100>
+compatible mpc5200: "fsl,mpc5200-immr"
+ mpc5200b: "fsl,mpc5200b-immr"
+system-frequency 'fsystem' frequency in Hz; XLB, IPB, USB and PCI
+ clocks are derived from the fsystem clock.
+bus-frequency IPB bus frequency in Hz. Clock rate
+ used by most of the soc devices.
+
+soc child nodes
+---------------
+Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
+
+Note: The tables below show the value for the mpc5200. A mpc5200b device
+tree should use the "fsl,mpc5200b-<device>","fsl,mpc5200-<device>" form.

+
+fsl,mpc5200-gpt nodes
+---------------------
+On the mpc5200 and 5200b, GPT0 has a watchdog timer function. If the board
+design supports the internal wdt, then the device node for GPT0 should
+include the empty property 'fsl,has-wdt'. Note that this does not activate
+the watchdog. The timer will function as a GPT if the timer api is used, and
+it will function as watchdog if the watchdog device is used. The watchdog
+mode has priority over the gpt mode, i.e. if the watchdog is activated, any
+gpt api call to this timer will fail with -EBUSY.
+
+If you add the property
+ fsl,wdt-on-boot = <n>;
+GPT0 will be marked as in-use watchdog, i.e. blocking every gpt access to it.
+If n>0, the watchdog is started with a timeout of n seconds. If n=0, the
+configuration of the watchdog is not touched. This is useful in two cases:
+- just mark GPT0 as watchdog, blocking gpt accesses, and configure it later;
+- do not touch a configuration assigned by the boot loader which supervises
+ the boot process itself.
+
+The watchdog will respect the CONFIG_WATCHDOG_NOWAYOUT option.
+
+An mpc5200-gpt can be used as a single line GPIO controller. To do so,
+add the following properties to the gpt node:
+ gpio-controller;
+ #gpio-cells = <2>;
+When referencing the GPIO line from another node, the first cell must always
+be zero and the second cell represents the gpio flags and described in the
+gpio device tree binding.
+
+An mpc5200-gpt can be used as a single line edge sensitive interrupt
+controller. To do so, add the following properties to the gpt node:
+ interrupt-controller;
+ #interrupt-cells = <1>;
+When referencing the IRQ line from another node, the cell represents the
+sense mode; 1 for edge rising, 2 for edge falling.
+
+fsl,mpc5200-psc nodes
+---------------------
+The PSCs should include a cell-index which is the index of the PSC in
+hardware. cell-index is used to determine which shared SoC registers to
+use when setting up PSC clocking. cell-index number starts at '0'. ie:
+ PSC1 has 'cell-index = <0>'
+ PSC4 has 'cell-index = <3>'
+
+PSC in i2s mode: The mpc5200 and mpc5200b PSCs are not compatible when in
+i2s mode. An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
+compatible field.
+
+
+fsl,mpc5200-gpio and fsl,mpc5200-gpio-wkup nodes
+------------------------------------------------
+Each GPIO controller node should have the empty property gpio-controller and
+#gpio-cells set to 2. First cell is the GPIO number which is interpreted
+according to the bit numbers in the GPIO control registers. The second cell
+is for flags which is currently unused.
+
+fsl,mpc5200-fec nodes
+---------------------
+The FEC node can specify one of the following properties to configure
+the MII link:
+- fsl,7-wire-mode - An empty property that specifies the link uses 7-wire
+ mode instead of MII
+- current-speed - Specifies that the MII should be configured for a fixed
+ speed. This property should contain two cells. The
+ first cell specifies the speed in Mbps and the second
+ should be '0' for half duplex and '1' for full duplex
+- phy-handle - Contains a phandle to an Ethernet PHY.
+
+Interrupt controller (fsl,mpc5200-pic) node
+-------------------------------------------
+The mpc5200 pic binding splits hardware IRQ numbers into two levels. The
+split reflects the layout of the PIC hardware itself, which groups
+interrupts into one of three groups; CRIT, MAIN or PERP. Also, the
+Bestcomm dma engine has its own set of interrupt sources which are
+cascaded off of peripheral interrupt 0, which the driver interprets as a
+fourth group, SDMA.
+
+The interrupts property for device nodes using the mpc5200 pic consists
+of three cells; <L1 L2 level>
+
+ L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
+ L2 := interrupt number; directly mapped from the value in the
+ "ICTL PerStat, MainStat, CritStat Encoded Register"
+ level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
+
+For external IRQs, use the following interrupt property values (how to
+specify external interrupts is a frequently asked question):
+External interrupts:
+ external irq0: interrupts = <0 0 n>;
+ external irq1: interrupts = <1 1 n>;
+ external irq2: interrupts = <1 2 n>;
+ external irq3: interrupts = <1 3 n>;
+'n' is sense (0: level high, 1: edge rising, 2: edge falling 3: level low)

+* FSL MPIC Message Registers
+
+This binding specifies what properties must be available in the device tree
+representation of the message register blocks found in some FSL MPIC
+implementations.
+
+Required properties:
+
+ - compatible: Specifies the compatibility list for the message register
+ block. The type shall be <string-list> and the value shall be of the form
+ "fsl,mpic-v<version>-msgr", where <version> is the version number of
+ the MPIC containing the message registers.
+
+ - reg: Specifies the base physical address(s) and size(s) of the
+ message register block's addressable register space. The type shall be
+ <prop-encoded-array>.
+
+ - interrupts: Specifies a list of interrupt-specifiers which are available
+ for receiving interrupts. Interrupt-specifier consists of two cells: first
+ cell is interrupt-number and second cell is level-sense. The type shall be
+ <prop-encoded-array>.
+
+Optional properties:
+
+ - mpic-msgr-receive-mask: Specifies what registers in the containing block
+ are allowed to receive interrupts. The value is a bit mask where a set
+ bit at bit 'n' indicates that message register 'n' can receive interrupts.
+ Note that "bit 'n'" is numbered from LSB for PPC hardware. The type shall
+ be <u32>. If not present, then all of the message registers in the block
+ are available.
+
+Aliases:
+
+ An alias should be created for every message register block. They are not
+ required, though. However, a particular implementation of this binding
+ may require aliases to be present. Aliases are of the form
+ 'mpic-msgr-block<n>', where <n> is an integer specifying the block's number.
+ Numbers shall start at 0.
+
+Example:
+
+ aliases {
+ mpic-msgr-block0 = &mpic_msgr_block0;
+ mpic-msgr-block1 = &mpic_msgr_block1;

+=====================================================================
+Freescale MPIC Interrupt Controller Node
+Copyright (C) 2010,2011 Freescale Semiconductor Inc.
+=====================================================================
+
+The Freescale MPIC interrupt controller is found on all PowerQUICC
+and QorIQ processors and is compatible with the Open PIC. The
+notable difference from Open PIC binding is the addition of 2
+additional cells in the interrupt specifier defining interrupt type
+information.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Shall include "fsl,mpic". Freescale MPIC
+ controllers compatible with this binding have Block
+ Revision Registers BRR1 and BRR2 at offset 0x0 and
+ 0x10 in the MPIC.
+
+ - reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies the physical
+ offset and length of the device's registers within the
+ CCSR address space.
+
+ - interrupt-controller
+ Usage: required
+ Value type: <empty>
+ Definition: Specifies that this node is an interrupt
+ controller
+
+ - #interrupt-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Shall be 2 or 4. A value of 2 means that interrupt
+ specifiers do not contain the interrupt-type or type-specific
+ information cells.
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Shall be 0.
+
+ - pic-no-reset
+ Usage: optional
+ Value type: <empty>
+ Definition: The presence of this property specifies that the
+ MPIC must not be reset by the client program, and that
+ the boot program has initialized all interrupt source
+ configuration registers to a sane state-- masked or
+ directed at other cores. This ensures that the client
+ program will not receive interrupts for sources not belonging
+ to the client. The presence of this property also mandates
+ that any initialization related to interrupt sources shall
+ be limited to sources explicitly referenced in the device tree.
+
+ - big-endian
+ Usage: optional
+ Value type: <empty>
+ If present the MPIC will be assumed to be big-endian. Some
+ device-trees omit this property on MPIC nodes even when the MPIC is
+ in fact big-endian, so certain boards override this property.
+
+ - single-cpu-affinity
+ Usage: optional
+ Value type: <empty>
+ If present the MPIC will be assumed to only be able to route
+ non-IPI interrupts to a single CPU at a time (EG: Freescale MPIC).
+
+ - last-interrupt-source
+ Usage: optional
+ Value type: <u32>
+ Some MPICs do not correctly report the number of hardware sources
+ in the global feature registers. If specified, this field will
+ override the value read from MPIC_GREG_FEATURE_LAST_SRC.
+
+INTERRUPT SPECIFIER DEFINITION
+
+ Interrupt specifiers consists of 4 cells encoded as
+ follows:
+
+ <1st-cell> interrupt-number
+
+ Identifies the interrupt source. The meaning
+ depends on the type of interrupt.
+
+ Note: If the interrupt-type cell is undefined
+ (i.e. #interrupt-cells = 2), this cell
+ should be interpreted the same as for
+ interrupt-type 0-- i.e. an external or
+ normal SoC device interrupt.
+
+ <2nd-cell> level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+ <3rd-cell> interrupt-type
+
+ The following types are supported:
+
+ 0 = external or normal SoC device interrupt
+
+ The interrupt-number cell contains
+ the SoC device interrupt number. The
+ type-specific cell is undefined. The
+ interrupt-number is derived from the
+ MPIC a block of registers referred to as
+ the "Interrupt Source Configuration Registers".
+ Each source has 32-bytes of registers
+ (vector/priority and destination) in this
+ region. So interrupt 0 is at offset 0x0,
+ interrupt 1 is at offset 0x20, and so on.
+
+ 1 = error interrupt
+
+ The interrupt-number cell contains
+ the SoC device interrupt number for
+ the error interrupt. The type-specific
+ cell identifies the specific error
+ interrupt number.
+
+ 2 = MPIC inter-processor interrupt (IPI)
+
+ The interrupt-number cell identifies
+ the MPIC IPI number. The type-specific
+ cell is undefined.
+
+ 3 = MPIC timer interrupt
+
+ The interrupt-number cell identifies
+ the MPIC timer number. The type-specific
+ cell is undefined.
+
+ <4th-cell> type-specific information
+
+ The type-specific cell is encoded as follows:
+
+ - For interrupt-type 1 (error interrupt),
+ the type-specific cell contains the
+ bit number of the error interrupt in the
+ Error Interrupt Summary Register.
+
+EXAMPLE 1
+ /*
+ * mpic interrupt controller with 4 cells per specifier
+ */
+ mpic: pic@40000 {
+ compatible = "fsl,mpic";
+ interrupt-controller;
+ #interrupt-cells = <4>;
+ #address-cells = <0>;
+ reg = <0x40000 0x40000>;

+ * interrupt number of 27. As per the reference manual
+ * this corresponds to interrupt source configuration
+ * registers at 0x5_0560.

+* Freescale MSI interrupt controller
+
+Required properties:
+- compatible : compatible list, may contain one or two entries
+ The first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
+ etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" or
+ "fsl,mpic-msi-v4.3" depending on the parent type and version. If mpic
+ version is 4.3, the number of MSI registers is increased to 16, MSIIR1 is
+ provided to access these 16 registers, and compatible "fsl,mpic-msi-v4.3"
+ should be used. The first entry is optional; the second entry is
+ required.
+
+- reg : It may contain one or two regions. The first region should contain
+ the address and the length of the shared message interrupt register set.
+ The second region should contain the address of aliased MSIIR or MSIIR1
+ register for platforms that have such an alias, if using MSIIR1, the second
+ region must be added because different MSI group has different MSIIR1 offset.
+
+- interrupts : each one of the interrupts here is one entry per 32 MSIs,
+ and routed to the host interrupt controller. the interrupts should
+ be set as edge sensitive. If msi-available-ranges is present, only
+ the interrupts that correspond to available ranges shall be present.
+
+Optional properties:
+- msi-available-ranges: use <start count> style section to define which
+ msi interrupt can be used in the 256 msi interrupts. This property is
+ optional, without this, all the MSI interrupts can be used.
+ Each available range must begin and end on a multiple of 32 (i.e.
+ no splitting an individual MSI register or the associated PIC interrupt).
+ MPIC v4.3 does not support this property because the 32 interrupts of an
+ individual register are not continuous when using MSIIR1.
+
+- msi-address-64: 64-bit PCI address of the MSIIR register. The MSIIR register
+ is used for MSI messaging. The address of MSIIR in PCI address space is
+ the MSI message address.
+
+ This property may be used in virtualized environments where the hypervisor
+ has created an alternate mapping for the MSIR block. See below for an
+ explanation.
+
+
+Example:
+ msi@41600 {
+ compatible = "fsl,mpc8610-msi", "fsl,mpic-msi";
+ reg = <0x41600 0x80>;

+ 0x107 0 0 0>;
+ };
+
+The Freescale hypervisor and msi-address-64
+-------------------------------------------
+Normally, PCI devices have access to all of CCSR via an ATMU mapping. The
+Freescale MSI driver calculates the address of MSIIR (in the MSI register
+block) and sets that address as the MSI message address.
+
+In a virtualized environment, the hypervisor may need to create an IOMMU
+mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement
+because of hardware limitations of the Peripheral Access Management Unit
+(PAMU), which is currently the only IOMMU that the hypervisor supports.
+The ATMU is programmed with the guest physical address, and the PAMU
+intercepts transactions and reroutes them to the true physical address.
+
+In the PAMU, each PCI controller is given only one primary window. The
+PAMU restricts DMA operations so that they can only occur within a window.
+Because PCI devices must be able to DMA to memory, the primary window must
+be used to cover all of the guest's memory space.
+
+PAMU primary windows can be divided into 256 subwindows, and each
+subwindow can have its own address mapping ("guest physical" to "true
+physical"). However, each subwindow has to have the same alignment, which
+means they cannot be located at just any address. Because of these
+restrictions, it is usually impossible to create a 4KB subwindow that
+covers MSIIR where it's normally located.
+
+Therefore, the hypervisor has to create a subwindow inside the same
+primary window used for memory, but mapped to the MSIR block (where MSIIR
+lives). The first subwindow after the end of guest memory is used for
+this. The address specified in the msi-address-64 property is the PCI
+address of MSIIR. The hypervisor configures the PAMU to map that address to
+the true physical address of MSIIR.

+Freescale Peripheral Management Access Unit (PAMU) Device Tree Binding
+
+DESCRIPTION
+
+The PAMU is an I/O MMU that provides device-to-memory access control and
+address translation capabilities.
+
+Required properties:
+
+- compatible : <string>
+ First entry is a version-specific string, such as
+ "fsl,pamu-v1.0". The second is "fsl,pamu".
+- ranges : <prop-encoded-array>
+ A standard property. Utilized to describe the memory mapped
+ I/O space utilized by the controller. The size should
+ be set to the total size of the register space of all
+ physically present PAMU controllers. For example, for
+ PAMU v1.0, on an SOC that has five PAMU devices, the size
+ is 0x5000.
+- interrupts : <prop-encoded-array>
+ Interrupt mappings. The first tuple is the normal PAMU
+ interrupt, used for reporting access violations. The second
+ is for PAMU hardware errors, such as PAMU operation errors
+ and ECC errors.
+- #address-cells: <u32>
+ A standard property.
+- #size-cells : <u32>
+ A standard property.
+
+Optional properties:
+- reg : <prop-encoded-array>
+ A standard property. It represents the CCSR registers of
+ all child PAMUs combined. Include it to provide support
+ for legacy drivers.
+- fsl,portid-mapping : <u32>
+ The Coherency Subdomain ID Port Mapping Registers and
+ Snoop ID Port Mapping registers, which are part of the
+ CoreNet Coherency fabric (CCF), provide a CoreNet
+ Coherency Subdomain ID/CoreNet Snoop ID to pamu mapping
+ functions. Certain bits from these registers should be
+ set if PAMUs should be snooped. This property defines
+ a bitmask which selects the bits that should be set if
+ PAMUs should be snooped.
+
+Child nodes:
+
+Each child node represents one PAMU controller. Each SOC device that is
+connected to a specific PAMU device should have a "fsl,pamu-phandle" property
+that links to the corresponding specific child PAMU controller.
+
+- reg : <prop-encoded-array>
+ A standard property. Specifies the physical address and
+ length (relative to the parent 'ranges' property) of this
+ PAMU controller's configuration registers. The size should
+ be set to the size of this PAMU controllers's register space.
+ For PAMU v1.0, this size is 0x1000.
+- fsl,primary-cache-geometry
+ : <prop-encoded-array>
+ Two cells that specify the geometry of the primary PAMU
+ cache. The first is the number of cache lines, and the
+ second is the number of "ways". For direct-mapped caches,
+ specify a value of 1.
+- fsl,secondary-cache-geometry
+ : <prop-encoded-array>
+ Two cells that specify the geometry of the secondary PAMU
+ cache. The first is the number of cache lines, and the
+ second is the number of "ways". For direct-mapped caches,
+ specify a value of 1.
+
+Device nodes:
+
+Devices that have LIODNs need to specify links to the parent PAMU controller
+(the actual PAMU controller that this device is connected to) and a pointer to
+the LIODN register, if applicable.
+
+- fsl,iommu-parent
+ : <phandle>
+ Phandle to the single, specific PAMU controller node to which
+ this device is connect. The PAMU topology is represented in
+ the device tree to assist code that dynamically determines the
+ best LIODN values to minimize PAMU cache thrashing.
+
+- fsl,liodn-reg : <prop-encoded-array>
+ Two cells that specify the location of the LIODN register
+ for this device. Required for devices that have a single
+ LIODN. The first cell is a phandle to a node that contains
+ the registers where the LIODN is to be set. The second is
+ the offset from the first "reg" resource of the node where
+ the specific LIODN register is located.
+
+
+Example:
+
+ iommu@20000 {
+ compatible = "fsl,pamu-v1.0", "fsl,pamu";
+ reg = <0x20000 0x5000>;
+ ranges = <0 0x20000 0x5000>;
+ fsl,portid-mapping = <0xf80000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ interrupts = <
+ 24 2 0 0

+
+Properties:
+- compatible: "fsl,<chip>-pmc".
+
+ "fsl,mpc8349-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8313-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8548-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8536-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8641d-pmc" should be listed for any chip whose PMC is
+ compatible; all statements below that apply to "fsl,mpc8548-pmc" also
+ apply to "fsl,mpc8641d-pmc".
+
+ Compatibility does not include bit assignments in SCCR/PMCDR/DEVDISR; these
+ bit assignments are indicated via the sleep specifier in each device's
+ sleep property.
+
+- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
+ is the PMC block, and the second resource is the Clock Configuration
+ block.
+
+ For devices compatible with "fsl,mpc8548-pmc", the first resource
+ is a 32-byte block beginning with DEVDISR.
+
+- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
+ resource is the PMC block interrupt.
+
+- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
+ this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
+ a wakeup source from deep sleep.
+
+Sleep specifiers:
+
+ fsl,mpc8349-pmc: Sleep specifiers consist of one cell. For each bit
+ that is set in the cell, the corresponding bit in SCCR will be saved
+ and cleared on suspend, and restored on resume. This sleep controller
+ supports disabling and resuming devices at any time.
+
+ fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
+ which will be ORed into PMCDR upon suspend, and cleared from PMCDR
+ upon resume. The first two cells are as described for fsl,mpc8578-pmc.
+ This sleep controller only supports disabling devices during system
+ sleep, or permanently.
+
+ fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
+ first of which will be ORed into DEVDISR (and the second into
+ DEVDISR2, if present -- this cell should be zero or absent if the
+ hardware does not have DEVDISR2) upon a request for permanent device
+ disabling. This sleep controller does not support configuring devices
+ to disable during system sleep (unless supported by another compatible
+ match), or dynamically.

+ibm,powerpc-cpu-features binding
+================================
+
+This device tree binding describes CPU features available to software, with
+enablement, privilege, and compatibility metadata.
+
+More general description of design and implementation of this binding is
+found in design.txt, which also points to documentation of specific features.
+
+
+/cpus/ibm,powerpc-cpu-features node binding
+-------------------------------------------
+
+Node: ibm,powerpc-cpu-features
+
+Description: Container of CPU feature nodes.
+
+The node name must be "ibm,powerpc-cpu-features".
+
+It is implemented as a child of the node "/cpus", but this must not be
+assumed by parsers.
+
+The node is optional but should be provided by new OPAL firmware.
+
+Properties:
+
+- compatible
+ Usage: required
+ Value type: string
+ Definition: "ibm,powerpc-cpu-features"
+
+ This compatibility refers to backwards compatibility of the overall
+ design with parsers that behave according to these guidelines. This can
+ be extended in a backward compatible manner which would not warrant a
+ revision of the compatible property.
+
+- isa
+ Usage: required
+ Value type: <u32>
+ Definition:
+
+ isa that the CPU is currently running in. This provides instruction set
+ compatibility, less the individual feature nodes. For example, an ISA v3.0
+ implementation that lacks the "transactional-memory" cpufeature node
+ should not use transactional memory facilities.
+
+ Value corresponds to the "Power ISA Version" multiplied by 1000.
+ For example, <3000> corresponds to Version 3.0, <2070> to Version 2.07.
+ The minor digit is available for revisions.
+
+- display-name
+ Usage: optional
+ Value type: string
+ Definition:
+
+ A human readable name for the CPU.
+
+/cpus/ibm,powerpc-cpu-features/example-feature node bindings
+----------------------------------------------------------------
+
+Each child node of cpu-features represents a CPU feature / capability.
+
+Node: A string describing an architected CPU feature, e.g., "floating-point".
+
+Description: A feature or capability supported by the CPUs.
+
+The name of the node is a human readable string that forms the interface
+used to describe features to software. Features are currently documented
+in the code where they are implemented in skiboot/core/cpufeatures.c
+
+Presence of the node indicates the feature is available.
+
+Properties:
+
+- isa
+ Usage: required
+ Value type: <u32>
+ Definition:
+
+ First level of the Power ISA that the feature appears in.
+ Software should filter out features when constraining the
+ environment to a particular ISA version.
+
+ Value is defined similarly to /cpus/features/isa
+
+- usable-privilege
+ Usage: required
+ Value type: <u32> bit mask
+ Definition:
+ Bit numbers are LSB0
+ bit 0 - PR (problem state / user mode)
+ bit 1 - OS (privileged state)
+ bit 2 - HV (hypervisor state)
+ All other bits reserved and should be zero.
+
+ This property describes the privilege levels and/or software components
+ that can use the feature.
+
+ If bit 0 is set, then the hwcap-bit-nr property will exist.
+
+
+- hv-support
+ Usage: optional
+ Value type: <u32> bit mask
+ Definition:
+ Bit numbers are LSB0
+ bit 0 - HFSCR
+ All other bits reserved and should be zero.
+
+ This property describes the HV privilege support required to enable the
+ feature to lesser privilege levels. If the property does not exist then no
+ support is required.
+
+ If no bits are set, the hypervisor must have explicit/custom support for
+ this feature.
+
+ If the HFSCR bit is set, then the hfscr-bit-nr property will exist and
+ the feature may be enabled by setting this bit in the HFSCR register.
+
+
+- os-support
+ Usage: optional
+ Value type: <u32> bit mask
+ Definition:
+ Bit numbers are LSB0
+ bit 0 - FSCR
+ All other bits reserved and should be zero.
+
+ This property describes the OS privilege support required to enable the
+ feature to lesser privilege levels. If the property does not exist then no
+ support is required.
+
+ If no bits are set, the operating system must have explicit/custom support
+ for this feature.
+
+ If the FSCR bit is set, then the fscr-bit-nr property will exist and
+ the feature may be enabled by setting this bit in the FSCR register.
+
+
+- hfscr-bit-nr
+ Usage: optional
+ Value type: <u32>
+ Definition: HFSCR bit position (LSB0)
+
+ This property exists when the hv-support property HFSCR bit is set. This
+ property describes the bit number in the HFSCR register that the
+ hypervisor must set in order to enable this feature.
+
+ This property also exists if an HFSCR bit corresponds with this feature.
+ This makes CPU feature parsing slightly simpler.
+
+
+- fscr-bit-nr
+ Usage: optional
+ Value type: <u32>
+ Definition: FSCR bit position (LSB0)
+
+ This property exists when the os-support property FSCR bit is set. This
+ property describes the bit number in the FSCR register that the
+ operating system must set in order to enable this feature.
+
+ This property also exists if an FSCR bit corresponds with this feature.
+ This makes CPU feature parsing slightly simpler.
+
+
+- hwcap-bit-nr
+ Usage: optional
+ Value type: <u32>
+ Definition: Linux ELF AUX vector bit position (LSB0)
+
+ This property may exist when the usable-privilege property value has PR bit set.
+ This property describes the bit number that should be set in the ELF AUX
+ hardware capability vectors in order to advertise this feature to userspace.

+IBM Power-Management Bindings
+=============================
+
+Linux running on baremetal POWER machines has access to the processor
+idle states. The description of these idle states is exposed via the
+node @power-mgt in the device-tree by the firmware.
+
+Definitions:
+----------------
+Typically each idle state has the following associated properties:
+
+- name: The name of the idle state as defined by the firmware.
+
+- flags: indicating some aspects of this idle states such as the
+ extent of state-loss, whether timebase is stopped on this
+ idle states and so on. The flag bits are as follows:
+
+- exit-latency: The latency involved in transitioning the state of the
+ CPU from idle to running.
+
+- target-residency: The minimum time that the CPU needs to reside in
+ this idle state in order to accrue power-savings
+ benefit.
+
+Properties
+----------------
+The following properties provide details about the idle states. These
+properties are exposed as arrays. Each entry in the property array
+provides the value of that property for the idle state associated with
+the array index of that entry.
+
+If idle-states are defined, then the properties
+"ibm,cpu-idle-state-names" and "ibm,cpu-idle-state-flags" are
+required. The other properties are required unless mentioned
+otherwise. The length of all the property arrays must be the same.
+
+- ibm,cpu-idle-state-names:
+ Array of strings containing the names of the idle states.
+
+- ibm,cpu-idle-state-flags:
+ Array of unsigned 32-bit values containing the values of the
+ flags associated with the aforementioned idle-states. The
+ flag bits are as follows:
+ 0x00000001 /* Decrementer would stop */
+ 0x00000002 /* Needs timebase restore */
+ 0x00001000 /* Restore GPRs like nap */
+ 0x00002000 /* Restore hypervisor resource from PACA pointer */
+ 0x00004000 /* Program PORE to restore PACA pointer */
+ 0x00010000 /* This is a nap state (POWER7,POWER8) */
+ 0x00020000 /* This is a fast-sleep state (POWER8)*/
+ 0x00040000 /* This is a winkle state (POWER8) */
+ 0x00080000 /* This is a fast-sleep state which requires a */
+ /* software workaround for restoring the */
+ /* timebase (POWER8) */
+ 0x00800000 /* This state uses SPR PMICR instruction */
+ /* (POWER8)*/
+ 0x00100000 /* This is a fast stop state (POWER9) */
+ 0x00200000 /* This is a deep-stop state (POWER9) */
+
+- ibm,cpu-idle-state-latencies-ns:
+ Array of unsigned 32-bit values containing the values of the
+ exit-latencies (in ns) for the idle states in
+ ibm,cpu-idle-state-names.
+
+- ibm,cpu-idle-state-residency-ns:
+ Array of unsigned 32-bit values containing the values of the
+ target-residency (in ns) for the idle states in
+ ibm,cpu-idle-state-names. On POWER8 this is an optional
+ property. If the property is absent, the target residency for
+ the "Nap", "FastSleep" are defined to 10000 and 300000000
+ respectively by the kernel. On POWER9 this property is required.
+
+- ibm,cpu-idle-state-psscr:
+ Array of unsigned 64-bit values containing the values for the
+ PSSCR for each of the idle states in ibm,cpu-idle-state-names.
+ This property is required on POWER9 and absent on POWER8.
+
+- ibm,cpu-idle-state-psscr-mask:
+ Array of unsigned 64-bit values containing the masks
+ indicating which psscr fields are set in the corresponding
+ entries of ibm,cpu-idle-state-psscr. This property is
+ required on POWER9 and absent on POWER8.
+
+ Whenever the firmware sets an entry in
+ ibm,cpu-idle-state-psscr-mask value to 0xf, it implies that
+ only the Requested Level (RL) field of the corresponding entry
+ in ibm,cpu-idle-state-psscr should be considered by the
+ kernel. For such idle states, the kernel would set the
+ remaining fields of the psscr to the following sane-default
+ values.
+
+ - ESL and EC bits are to 1. So wakeup from any stop
+ state will be at vector 0x100.
+
+ - MTL and PSLL are set to the maximum allowed value as
+ per the ISA, i.e. 15.
+
+ - The Transition Rate, TR is set to the Maximum value
+ 3.
+
+ For all the other values of the entry in
+ ibm,cpu-idle-state-psscr-mask, the kernel expects all the
+ psscr fields of the corresponding entry in
+ ibm,cpu-idle-state-psscr to be correctly set by the firmware.
+
+- ibm,cpu-idle-state-pmicr:
+ Array of unsigned 64-bit values containing the pmicr values
+ for the idle states in ibm,cpu-idle-state-names. This 64-bit
+ register value is to be set in pmicr for the corresponding
+ state if the flag indicates that pmicr SPR should be set. This
+ is an optional property on POWER8 and is absent on
+ POWER9.
+
+- ibm,cpu-idle-state-pmicr-mask:
+ Array of unsigned 64-bit values containing the mask indicating
+ which of the fields of the PMICR are set in the corresponding
+ entries in ibm,cpu-idle-state-pmicr. This is an optional
+ property on POWER8 and is absent on POWER9.

+
+maintainers:
+ - Rob Herring <robh@kernel.org>
+
+description: |
+ Devices on SOCs often have mechanisms for placing devices into low-power
+ states that are decoupled from the devices' own register blocks. Sometimes,
+ this information is more complicated than a cell-index property can
+ reasonably describe. Thus, each device controlled in such a manner
+ may contain a "sleep" property which describes these connections.
+
+ The sleep property consists of one or more sleep resources, each of
+ which consists of a phandle to a sleep controller, followed by a
+ controller-specific sleep specifier of zero or more cells.
+
+ The semantics of what type of low power modes are possible are defined
+ by the sleep controller. Some examples of the types of low power modes
+ that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+ awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+ reset).
+
+ Some devices may share a clock domain with each other, such that they should
+ only be suspended when none of the devices are in use. Where reasonable,
+ such nodes should be placed on a virtual bus, where the bus has the sleep
+ property. If the clock domain is shared among devices that cannot be
+ reasonably grouped in this manner, then create a virtual sleep controller
+ (similar to an interrupt nexus, except that defining a standardized
+ sleep-map should wait until its necessity is demonstrated).

+ZHAW InES PTP time stamping IP core
+
+The IP core needs two different kinds of nodes. The control node
+lives somewhere in the memory map and specifies the address of the
+control registers. There can be up to three port handles placed as
+attributes of PHY nodes. These associate a particular MII bus with a
+port index within the IP core.
+
+Required properties of the control node:
+
+- compatible: "ines,ptp-ctrl"
+- reg: physical address and size of the register bank
+
+Required format of the port handle within the PHY node:
+
+- timestamper: provides control node reference and
+ the port channel within the IP core
+
+Example:
+
+ tstamper: timestamper@60000000 {
+ compatible = "ines,ptp-ctrl";
+ reg = <0x60000000 0x80>;
+ };
+

+* Freescale QorIQ 1588 timer based PTP clock
+
+General Properties:
+
+ - compatible Should be "fsl,etsec-ptp" for eTSEC
+ Should be "fsl,fman-ptp-timer" for DPAA FMan
+ Should be "fsl,dpaa2-ptp" for DPAA2
+ Should be "fsl,enetc-ptp" for ENETC
+ - reg Offset and length of the register set for the device
+ - interrupts There should be at least two interrupts. Some devices
+ have as many as four PTP related interrupts.
+
+Clock Properties:
+
+ - fsl,cksel Timer reference clock source.
+ - fsl,tclk-period Timer reference clock period in nanoseconds.
+ - fsl,tmr-prsc Prescaler, divides the output clock.
+ - fsl,tmr-add Frequency compensation value.
+ - fsl,tmr-fiper1 Fixed interval period pulse generator.
+ - fsl,tmr-fiper2 Fixed interval period pulse generator.
+ - fsl,tmr-fiper3 Fixed interval period pulse generator.
+ Supported only on DPAA2 and ENETC hardware.
+ - fsl,max-adj Maximum frequency adjustment in parts per billion.
+ - fsl,extts-fifo The presence of this property indicates hardware
+ support for the external trigger stamp FIFO.
+ - little-endian The presence of this property indicates the 1588 timer
+ IP block is little-endian mode. The default endian mode
+ is big-endian.
+
+ These properties set the operational parameters for the PTP
+ clock. You must choose these carefully for the clock to work right.
+ Here is how to figure good values:
+
+ TimerOsc = selected reference clock MHz
+ tclk_period = desired clock period nanoseconds
+ NominalFreq = 1000 / tclk_period MHz
+ FreqDivRatio = TimerOsc / NominalFreq (must be greater that 1.0)
+ tmr_add = ceil(2^32 / FreqDivRatio)
+ OutputClock = NominalFreq / tmr_prsc MHz
+ PulseWidth = 1 / OutputClock microseconds
+ FiperFreq1 = desired frequency in Hz
+ FiperDiv1 = 1000000 * OutputClock / FiperFreq1
+ tmr_fiper1 = tmr_prsc * tclk_period * FiperDiv1 - tclk_period
+ max_adj = 1000000000 * (FreqDivRatio - 1.0) - 1
+
+ The calculation for tmr_fiper2 is the same as for tmr_fiper1. The
+ driver expects that tmr_fiper1 will be correctly set to produce a 1
+ Pulse Per Second (PPS) signal, since this will be offered to the PPS
+ subsystem to synchronize the Linux clock.
+
+ Reference clock source is determined by the value, which is holded
+ in CKSEL bits in TMR_CTRL register. "fsl,cksel" property keeps the
+ value, which will be directly written in those bits, that is why,
+ according to reference manual, the next clock sources can be used:
+
+ For eTSEC,
+ <0> - external high precision timer reference clock (TSEC_TMR_CLK
+ input is used for this purpose);
+ <1> - eTSEC system clock;
+ <2> - eTSEC1 transmit clock;
+ <3> - RTC clock input.
+
+ For DPAA FMan,
+ <0> - external high precision timer reference clock (TMR_1588_CLK)
+ <1> - MAC system clock (1/2 FMan clock)
+ <2> - reserved
+ <3> - RTC clock oscillator
+
+ When this attribute is not used, the IEEE 1588 timer reference clock
+ will use the eTSEC system clock (for Gianfar) or the MAC system
+ clock (for DPAA).
+
+Example:
+
+ ptp_clock@24e00 {
+ compatible = "fsl,etsec-ptp";
+ reg = <0x24E00 0xB0>;
+ interrupts = <12 0x8 13 0x8>;
+ interrupt-parent = < &ipic >;
+ fsl,cksel = <1>;
+ fsl,tclk-period = <10>;
+ fsl,tmr-prsc = <100>;
+ fsl,tmr-add = <0x999999A4>;
+ fsl,tmr-fiper1 = <0x3B9AC9F6>;
+ fsl,tmr-fiper2 = <0x00018696>;
+ fsl,max-adj = <659999998>;

+Time stamps from MII bus snooping devices
+
+This binding supports non-PHY devices that snoop the MII bus and
+provide time stamps. In contrast to PHY time stamping drivers (which
+can simply attach their interface directly to the PHY instance), stand
+alone MII time stamping drivers use this binding to specify the
+connection between the snooping device and a given network interface.
+
+Non-PHY MII time stamping drivers typically talk to the control
+interface over another bus like I2C, SPI, UART, or via a memory mapped
+peripheral. This controller device is associated with one or more
+time stamping channels, each of which snoops on a MII bus.
+
+The "timestamper" property lives in a phy node and links a time
+stamping channel from the controller device to that phy's MII bus.
+
+Example:
+
+ tstamper: timestamper@10000000 {
+ compatible = "ines,ptp-ctrl";
+ reg = <0x10000000 0x80>;
+ };
+
+ ethernet@20000000 {
+ mdio {
+ ethernet-phy@1 {
+ timestamper = <&tstamper 0>;
+ };
+ };
+ };
+
+ ethernet@30000000 {
+ mdio {
+ ethernet-phy@2 {
+ timestamper = <&tstamper 1>;
+ };
+ };
+ };
+
+In this example, time stamps from the MII bus attached to phy@1 will
+appear on time stamp channel 0 (zero), and those from phy@2 appear on
+channel 1.

+ A 16 bit wide "SHADOW_REG_EN" parameter of the IP core controls whether synchronous
+ mode is possible for each channel, and is set by the bitstream programmed to the
+ FPGA. If the IP core is instantiated with SHADOW_REG_ENx=1, both registers that
+ control the duty cycle for channel x have a second "shadow"/buffer reg synthesised.
+ At runtime a bit wide register exposed to APB can be used to toggle on/off
+ synchronised mode for all channels it has been synthesised for.
+ Each bit of "microchip,sync-update-mask" corresponds to a PWM channel & represents

+ standard PWM algorithm can achieve. A 16 bit DAC_MODE module parameter of the IP
+ core, set at instantiation and by the bitstream programmed to the FPGA, determines
+ whether a given channel operates in regular PWM or DAC mode.
+ Each bit corresponds to a PWM channel & represents whether DAC mode is enabled

+Freescale FlexTimer Module (FTM) PWM controller
+
+The same FTM PWM device can have a different endianness on different SoCs. The
+device tree provides a property to describing this so that an operating system
+device driver can handle all variants of the device. Refer to the table below
+for the endianness of the FTM PWM block as integrated into the existing SoCs:
+
+ SoC | FTM-PWM endianness
+ --------+-------------------
+ Vybrid | LE
+ LS1 | BE
+ LS2 | LE
+
+Please see ../regmap/regmap.txt for more detail about how to specify endian
+modes in device tree.
+
+
+Required properties:
+- compatible : should be "fsl,<soc>-ftm-pwm" and one of the following
+ compatible strings:
+ - "fsl,vf610-ftm-pwm" for PWM compatible with the one integrated on VF610
+ - "fsl,imx8qm-ftm-pwm" for PWM compatible with the one integrated on i.MX8QM
+- reg: Physical base address and length of the controller's registers
+- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
+ the cells format.
+- clock-names: Should include the following module clock source entries:
+ "ftm_sys" (module clock, also can be used as counter clock),
+ "ftm_ext" (external counter clock),
+ "ftm_fix" (fixed counter clock),
+ "ftm_cnt_clk_en" (external and fixed counter clock enable/disable).
+- clocks: Must contain a phandle and clock specifier for each entry in
+ clock-names, please see clock/clock-bindings.txt for details of the property
+ values.
+- pinctrl-names: Must contain a "default" entry.
+- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
+ See pinctrl/pinctrl-bindings.txt for details of the property values.
+- big-endian: Boolean property, required if the FTM PWM registers use a big-

+ achievable period. PWM RTL that corresponds to the IP block version

+Specifying PWM information for devices
+======================================
+
+1) PWM user nodes
+-----------------
+
+PWM users should specify a list of PWM devices that they want to use
+with a property containing a 'pwm-list':
+
+ pwm-list ::= <single-pwm> [pwm-list]
+ single-pwm ::= <pwm-phandle> <pwm-specifier>
+ pwm-phandle : phandle to PWM controller node
+ pwm-specifier : array of #pwm-cells specifying the given PWM
+ (controller specific)
+
+PWM properties should be named "pwms". The exact meaning of each pwms
+property must be documented in the device tree binding for each device.
+An optional property "pwm-names" may contain a list of strings to label
+each of the PWM devices listed in the "pwms" property. If no "pwm-names"
+property is given, the name of the user node will be used as fallback.
+
+Drivers for devices that use more than a single PWM device can use the
+"pwm-names" property to map the name of the PWM device requested by the
+pwm_get() call to an index into the list given by the "pwms" property.
+
+The following example could be used to describe a PWM-based backlight
+device:
+
+ pwm: pwm {
+ #pwm-cells = <2>;
+ };
+
+ [...]
+
+ bl: backlight {
+ pwms = <&pwm 0 5000000>;
+ pwm-names = "backlight";
+ };
+
+Note that in the example above, specifying the "pwm-names" is redundant
+because the name "backlight" would be used as fallback anyway.
+
+pwm-specifier typically encodes the chip-relative PWM number and the PWM
+period in nanoseconds.
+
+Optionally, the pwm-specifier can encode a number of flags (defined in
+<dt-bindings/pwm/pwm.h>) in a third cell:
+- PWM_POLARITY_INVERTED: invert the PWM signal polarity
+
+Example with optional PWM specifier for inverse polarity
+
+ bl: backlight {
+ pwms = <&pwm 0 5000000 PWM_POLARITY_INVERTED>;
+ pwm-names = "backlight";
+ };
+
+2) PWM controller nodes
+-----------------------
+
+See pwm.yaml.

+
+Note:
+Regmap defaults to little-endian register access on MMIO based
+devices, this is by far the most common setting. On CPU
+architectures that typically run big-endian operating systems
+(e.g. PowerPC), registers can be defined as big-endian and must
+be marked that way in the devicetree.
+
+On SoCs that can be operated in both big-endian and little-endian
+modes, with a single hardware switch controlling both the endianness
+of the CPU and a byteswap for MMIO registers (e.g. many Broadcom MIPS
+chips), "native-endian" is used to allow using the same device tree
+blob in both cases.
+
+Examples:
+Scenario 1 : a register set in big-endian mode.

+Regulator of AMS AS3722 PMIC.
+Name of the regulator subnode must be "regulators".
+
+Optional properties:
+--------------------
+The input supply of regulators are the optional properties on the
+regulator node. The AS3722 is having 7 DCDC step-down regulators as
+sd[0-6], 10 LDOs as ldo[0-7], ldo[9-11]. The input supply of these
+regulators are provided through following properties:
+vsup-sd2-supply: Input supply for SD2.
+vsup-sd3-supply: Input supply for SD3.
+vsup-sd4-supply: Input supply for SD4.
+vsup-sd5-supply: Input supply for SD5.
+vin-ldo0-supply: Input supply for LDO0.
+vin-ldo1-6-supply: Input supply for LDO1 and LDO6.
+vin-ldo2-5-7-supply: Input supply for LDO2, LDO5 and LDO7.

+vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
+vin-ldo11-supply: Input supply for LDO11.
+
+Optional nodes:
+--------------
+- regulators : Must contain a sub-node per regulator from the list below.
+ Each sub-node should contain the constraints and initialization
+ information for that regulator. See regulator.txt for a
+ description of standard properties for these sub-nodes.
+ Additional custom properties are listed below.
+ sd[0-6], ldo[0-7], ldo[9-11].
+
+ Optional sub-node properties:
+ ----------------------------
+ ams,ext-control: External control of the rail. The option of
+ this properties will tell which external input is
+ controlling this rail. Valid values are 0, 1, 2 ad 3.
+ 0: There is no external control of this rail.
+ 1: Rail is controlled by ENABLE1 input pin.
+ 2: Rail is controlled by ENABLE2 input pin.
+ 3: Rail is controlled by ENABLE3 input pin.
+ ams,enable-tracking: Enable tracking with SD1, only supported
+ by LDO3.

+ documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The

+
+Required properties (not on ldo3, ldo4):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+ values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, and ldo2 can regulate the feedback reference from
+0.3625 V to 0.75 V in 12.5 mV steps. The output voltage thus ranges between
+0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1
+have a fixed 0.8 V reference and thus output 0.8 * (1 + R1/R2) V. The ldo3
+regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4
+regulator can output between 1.8 V and 3.3 V on LTC3589 and between 1.2 V
+and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not

+MAX8907 regulator
+
+Required properties:
+- compatible: "maxim,max8907"
+- reg: I2C slave address
+- interrupts: The interrupt output of the controller
+- mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
+- in-v1-supply: The input supply for SD1.
+- in-v2-supply: The input supply for SD2.
+- in-v3-supply: The input supply for SD3.
+- in1-supply: The input supply for LDO1.
+...
+- in20-supply: The input supply for LDO20.
+- regulators: A node that houses a sub-node for each regulator within the
+ device. Each sub-node is identified using the node's name (or the deprecated
+ regulator-compatible property if present), with valid values listed below.
+ The content of each sub-node is defined by the standard binding for
+ regulators; see regulator.txt.
+
+Optional properties:
+- maxim,system-power-controller: Boolean property indicating that the PMIC
+ controls the overall system power.
+
+The valid names for regulators are:
+
+ sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,

+ regulators.
+
+ See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for

+
+ Certain regulators support "regulator-initial-mode" and "regulator-mode".
+ The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
+ and their meaning is::
+ 1 - Normal regulator voltage output mode.
+ 3 - Low Power which reduces the quiescent current down to only 1uA
+
+ The standard "regulator-mode" property can only be used for regulators that
+ support changing their mode to Low Power Mode during suspend. These
+ regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
+ regulator has been enabled for the given suspend state using
+ "regulator-on-in-suspend" and has not been disabled for that state using
+ "regulator-off-in-suspend".

+MCP16502 PMIC
+
+Required properties:
+- compatible: "microchip,mcp16502"
+- reg: I2C slave address
+- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
+ suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
+ property is optional;
+- regulators: A node that houses a sub-node for each regulator within
+ the device. Each sub-node is identified using the node's
+ name. The content of each sub-node is defined by the
+ standard binding for regulators; see regulator.txt.
+
+Regulators of MCP16502 PMIC:
+1) VDD_IO - Buck (1.2 - 3.7 V)
+2) VDD_DDR - Buck (0.6 - 1.85 V)
+3) VDD_CORE - Buck (0.6 - 1.85 V)
+4) VDD_OTHER - BUCK (0.6 - 1.85 V)
+5) LDO1 - LDO (1.2 - 3.7 V)
+6) LDO2 - LDO (1.2 - 3.7 V)
+
+Regulator modes:
+2 - FPWM: higher precision, higher consumption
+4 - AutoPFM: lower precision, lower consumption
+
+Each regulator is defined using the standard binding for regulators.

+MediaTek MT6358 Regulator
+
+All voltage regulators provided by the MT6358 PMIC are described as the
+subnodes of the MT6358 regulators node. Each regulator is named according
+to its regulator type, buck_<name> and ldo_<name>. The definition for each
+of these nodes is defined using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are::
+BUCK:
+ buck_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
+ buck_vs2, buck_vmodem, buck_vs1
+LDO:
+ ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
+ ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
+ ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
+ ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+ as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+ as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+ as the "CPU domain" voltage regulator.
+
+Example:
+
+ pmic {
+ regulators {
+ core_vdd_reg: core {
+ regulator-name = "vdd_core";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-core-regulator;
+ };
+
+ rtc_vdd_reg: rtc {
+ regulator-name = "vdd_rtc";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-rtc-regulator;
+ };
+
+ cpu_vdd_reg: cpu {
+ regulator-name = "vdd_cpu";
+ regulator-min-microvolt = <750000>;
+ regulator-max-microvolt = <1125000>;
+ regulator-coupled-with = <&core_vdd_reg &rtc_vdd_reg>;
+ regulator-coupled-max-spread = <550000 550000>;
+
+ nvidia,tegra-cpu-regulator;
+ };
+ };
+ };

+- interrupts-name: The names of the individual interrupts.
+
+Optional properties:
+- ti,ldo6-vibrator : ldo6 is in vibrator mode
+
+Optional nodes:
+- regulators : Must contain a sub-node per regulator from the list below.
+ Each sub-node should contain the constraints and initialization
+ information for that regulator. See regulator.txt for a
+ description of standard properties for these sub-nodes.
+ Additional custom properties are listed below.
+
+ For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
+ smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
+ smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
+
+ Optional sub-node properties:
+ ti,warm-reset - maintain voltage during warm reset(boolean)
+ ti,roof-floor - This takes as optional argument on platform supporting
+ the rail from desired external control. If there is no argument then
+ it will be assume that it is controlled by NSLEEP pin.
+ The valid value for external pins are:
+ ENABLE1 then 1,
+ ENABLE2 then 2 or
+ NSLEEP then 3.
+ ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
+ 2 - eco, 3 - forced pwm
+ ti,smps-range - OTP has the wrong range set for the hardware so override
+ 0 - low range, 1 - high range.
+
+- ti,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+pmic {

+description: |
+ Currently supports 2 modes of operation:
+
+ Voltage Table:
+ When in this mode, a voltage table (See below) of predefined voltage <=>
+ duty-cycle values must be provided via DT. Limitations are that the
+ regulator can only operate at the voltages supplied in the table.
+ Intermediary duty-cycle values which would normally allow finer grained
+ voltage selection are ignored and rendered useless. Although more control
+ is given to the user if the assumptions made in continuous-voltage mode do
+ not reign true.
+
+ Continuous Voltage:
+ This mode uses the regulator's maximum and minimum supplied voltages
+ specified in the regulator-{min,max}-microvolt properties to calculate
+ appropriate duty-cycle values. This allows for a much more fine grained
+ solution when compared with voltage-table mode above. This solution does
+ make an assumption that a %50 duty-cycle value will cause the regulator
+ voltage to run at half way between the supplied max_uV and min_uV values.
+
+ If voltage-table is provided, then the device will be used in Voltage Table
+ Mode. If no voltage-table is provided, then the device will be used in
+ Continuous Voltage Mode.

+description: |
+ rpmh-regulator devices support PMIC regulator management via the Voltage
+ Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators.
+ The APPS processor communicates with these hardware blocks via a
+ Resource State Coordinator (RSC) using command packets. The VRM allows
+ changing three parameters for a given regulator, enable state, output
+ voltage, and operating mode. The XOB allows changing only a single
+ parameter for a given regulator, its enable state. Despite its name,
+ the XOB is capable of controlling the enable state of any PMIC peripheral.
+ It is used for clock buffers, low-voltage switches, and LDO/SMPS regulators
+ which have a fixed voltage and mode.
+
+ =======================
+ Required Node Structure
+ =======================
+
+ RPMh regulators must be described in two levels of device nodes. The first
+ level describes the PMIC containing the regulators and must reside within an
+ RPMh device node. The second level describes each regulator within the PMIC
+ which is to be used on the board. Each of these regulators maps to a single
+ RPMh resource.
+
+ The names used for regulator nodes must match those supported by a given
+ PMIC. Supported regulator node names are
+ For PM6150, smps1 - smps5, ldo1 - ldo19
+ For PM6150L, smps1 - smps8, ldo1 - ldo11, bob
+ For PM6350, smps1 - smps5, ldo1 - ldo22
+ For PM660, smps1 - smps6, ldo1 - ldo3, ldo5 - ldo19
+ For PM660L, smps1 - smps3, smps5, ldo1 - ldo8, bob
+ For PM7325, smps1 - smps8, ldo1 - ldo19
+ For PM8005, smps1 - smps4
+ For PM8009, smps1 - smps2, ldo1 - ldo7
+ For PM8150, smps1 - smps10, ldo1 - ldo18
+ For PM8150L, smps1 - smps8, ldo1 - ldo11, bob, flash, rgb

+title: QCOM SMD RPM REGULATOR
+
+description:
+ The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+ Because SMD is used as the communication transport mechanism, the RPM
+ resides as a subnode of the SMD. As such, the SMD-RPM regulator requires
+ that the SMD and RPM nodes be present.
+
+ Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.yaml for
+ information pertaining to the SMD node.
+
+ Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.yaml
+ for information regarding the RPM node.
+
+ The regulator node houses sub-nodes for each regulator within the device.
+ Each sub-node is identified using the node's name, with valid values listed
+ for each of the pmics below.

+Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
+
+Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
+of these regulators are defined under parent device node.
+Details of regulator properties are defined as child node under
+sub-node "regulators" which is child node of device node.
+
+Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
+for common regulator bindings used by client.
+
+Following are properties of parent node related to regulators.
+
+Optional properties:
+-------------------
+The input supply of regulators are the optional properties on the
+parent device node. The input supply of these regulators are provided
+through following properties:
+in-sd0-supply: Input supply for SD0, INA-SD0 or INB-SD0 pins.
+in-sd1-supply: Input supply for SD1.
+in-sd2-supply: Input supply for SD2.
+in-sd3-supply: Input supply for SD3.
+in-ldo0-1-supply: Input supply for LDO0 and LDO1.
+in-ldo2-supply: Input supply for LDO2.
+in-ldo3-5-supply: Input supply for LDO3 and LDO5
+in-ldo4-6-supply: Input supply for LDO4 and LDO6.
+in-ldo7-8-supply: Input supply for LDO7 and LDO8.
+
+Optional sub nodes for regulators under "regulators" subnode:
+------------------------------------------------------------
+The subnodes name is the name of regulator and it must be one of:
+ sd[0-3], ldo[0-8]
+
+Each sub-node should contain the constraints and initialization
+information for that regulator. The definition for each of these
+nodes is defined using the standard binding for regulators found at
+<Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+There are also additional properties for SD/LDOs. These additional properties
+are required to configure FPS configuration parameters for SDs and LDOs.
+Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
+Power Sequence (FPS).
+Following are additional properties:
+
+- maxim,active-fps-source: FPS source for the regulators to get
+ enabled/disabled when system is in
+ active state. Valid values are:
+ - MAX77620_FPS_SRC_0,
+ FPS source is FPS0.
+ - MAX77620_FPS_SRC_1,
+ FPS source is FPS1
+ - MAX77620_FPS_SRC_2 and
+ FPS source is FPS2
+ - MAX77620_FPS_SRC_NONE.
+ Regulator is not controlled
+ by FPS events and it gets
+ enabled/disabled by register
+ access.
+ Absence of this property will leave
+ the FPS configuration register for that
+ regulator to default configuration.
+
+- maxim,active-fps-power-up-slot: Sequencing event slot number on which
+ the regulator get enabled when
+ master FPS input event set to HIGH.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,active-fps-power-down-slot: Sequencing event slot number on which
+ the regulator get disabled when master
+ FPS input event set to LOW.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,suspend-fps-source: This is same as property
+ "maxim,active-fps-source" but value
+ get configured when system enters in
+ to suspend state.
+
+- maxim,suspend-fps-power-up-slot: This is same as property
+ "maxim,active-fps-power-up-slot" but
+ this value get configured into FPS
+ configuration register when system
+ enters into suspend.
+ This is applicable if suspend state
+ FPS source is selected as FPS0, FPS1 or
+
+- maxim,suspend-fps-power-down-slot: This is same as property
+ "maxim,active-fps-power-down-slot" but
+ this value get configured into FPS
+ configuration register when system
+ enters into suspend.
+ This is applicable if suspend state
+ FPS source is selected as FPS0, FPS1 or
+ FPS2.
+- maxim,ramp-rate-setting: integer, ramp rate(uV/us) setting to be
+ configured to the device.
+ The platform may have different ramp
+ rate than advertised ramp rate if it has
+ design variation from Maxim's
+ recommended. On this case, platform
+ specific ramp rate is used for ramp time
+ calculation and this property is used
+ for device register configurations.
+ The measured ramp rate of platform is
+ provided by the regulator-ramp-delay
+ as described in <devicetree/bindings/
+ regulator/regulator.txt>.
+ Maxim Max77620 supports following ramp
+ delay:
+ SD: 13.75mV/us, 27.5mV/us, 55mV/us
+ LDOs: 5mV/us, 100mV/us
+
+Note: If the measured ramp delay is same as advertised ramp delay then it is not
+required to provide the ramp delay with property "maxim,ramp-rate-setting". The
+ramp rate can be provided by the regulator-ramp-delay which will be used for
+ramp time calculation for voltage change as well as for device configuration.

+description: |
+ The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for
+ 32-bit and 64-bit MCU and MPU applications. It supports DDR3, DDR3L, DDR4,
+ and LPDDR4 memory power requirements. The internally compensated regulators,
+ built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell
+ battery charger provide a highly integrated, small footprint power solution
+ ideal for System-On-Module (SOM) applications. A spread spectrum feature
+ provides an ease-of-use solution for noise-sensitive audio or RF applications.
+
+ This device exposes two devices via I2C. One for the integrated RTC IP, and
+ one for everything else.

+description: |
+ RTQ2208 is a highly integrated power converter that offers functional safety dual
+ multi-configurable synchronous buck converters and two LDOs.
+
+ Bucks support "regulator-allowed-modes" and "regulator-mode". The former defines the permitted
+ switching operation in normal mode; the latter defines the operation in suspend to RAM mode.
+
+ No matter the RTQ2208 is configured to normal or suspend to RAM mode, there are two switching
+ operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
+ conduction mode (FCCM).
+
+ The definition of modes is in the datasheet which is available in below link
+ and their meaning is::
+ 0 - Auto mode for power saving, which reducing the switching frequency at light load condition
+ to maintain high frequency.
+ 1 - FCCM to meet the strict voltage regulation accuracy, which keeping constant switching frequency.
+
+ Datasheet will be available soon at
+ https://www.richtek.com/assets/Products

+Spreadtrum SC2731 Voltage regulators
+
+The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
+14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have

+
+Required properties:
+ - compatible: should be "sprd,sc27xx-regulator".

+Adaptive Body Bias(ABB) SoC internal LDO regulator for Texas Instruments SoCs
+
+Required Properties:
+- compatible: Should be one of:
+ - "ti,abb-v1" for older SoCs like OMAP3
+ - "ti,abb-v2" for newer SoCs like OMAP4, OMAP5
+ - "ti,abb-v3" for a generic definition where setup and control registers are
+ provided (example: DRA7)
+- reg: Address and length of the register set for the device. It contains
+ the information of registers in the same order as described by reg-names
+- reg-names: Should contain the reg names
+ - "base-address" - contains base address of ABB module (ti,abb-v1,ti,abb-v2)
+ - "control-address" - contains control register address of ABB module (ti,abb-v3)
+ - "setup-address" - contains setup register address of ABB module (ti,abb-v3)
+ - "int-address" - contains address of interrupt register for ABB module
+ (also see Optional properties)
+- #address-cells: should be 0
+- #size-cells: should be 0
+- clocks: should point to the clock node used by ABB module
+- ti,settling-time: Settling time in uSecs from SoC documentation for ABB module
+ to settle down(target time for SR2_WTCNT_VALUE).
+- ti,clock-cycles: SoC specific data about count of system ti,clock-cycles used for
+ computing settling time from SoC Documentation for ABB module(clock
+ cycles for SR2_WTCNT_VALUE).
+- ti,tranxdone-status-mask: Mask to the int-register to write-to-clear mask
+ indicating LDO tranxdone (operation complete).
+- ti,abb_info: An array of 6-tuples u32 items providing information about ABB
+ configuration needed per operational voltage of the device.
+ Each item consists of the following in the same order:
+ volt: voltage in uV - Only used to index ABB information.
+ ABB mode: one of the following:
+ 0-bypass
+ 1-Forward Body Bias(FBB)
+ 3-Reverse Body Bias(RBB)
+ efuse: (see Optional properties)
+ RBB enable efuse Mask: (See Optional properties)
+ FBB enable efuse Mask: (See Optional properties)
+ Vset value efuse Mask: (See Optional properties)
+
+ NOTE: If more than 1 entry is present, then regulator is setup to change
+ voltage, allowing for various modes to be selected indexed off
+ the regulator. Further, ABB LDOs are considered always-on by
+ default.
+
+Optional Properties:
+- reg-names: In addition to the required properties, the following are optional
+ - "efuse-address" - Contains efuse base address used to pick up ABB info.
+ - "ldo-address" - Contains address of ABB LDO override register.
+ "efuse-address" is required for this.
+- ti,ldovbb-vset-mask - Required if ldo-address is set, mask for LDO override
+ register to provide override vset value.
+- ti,ldovbb-override-mask - Required if ldo-address is set, mask for LDO
+ override register to enable override vset value.
+- ti,abb_opp_sel: Addendum to the description in required properties
+ efuse: Mandatory if 'efuse-address' register is defined. Provides offset
+ from efuse-address to pick up ABB characteristics. Set to 0 if
+ 'efuse-address' is not defined.
+ RBB enable efuse Mask: Optional if 'efuse-address' register is defined.
+ 'ABB mode' is force set to RBB mode if value at "efuse-address"
+ + efuse maps to RBB mask. Set to 0 to ignore this.
+ FBB enable efuse Mask: Optional if 'efuse-address' register is defined.
+ 'ABB mode' is force set to FBB mode if value at "efuse-address"
+ + efuse maps to FBB mask (valid only if RBB mask does not match)
+ Set to 0 to ignore this.
+ Vset value efuse Mask: Mandatory if ldo-address is set. Picks up from
+ efuse the value to set in 'ti,ldovbb-vset-mask' at ldo-address.
+

+- ovp-threshold-percent : overvoltage protection (OVP) threshold of the
+ regulator in percent. Some regulators have an OVP
+ circuitry which shuts down the regulator when the
+ actual output voltage deviates beyond a certain
+ margin from the expected value for a given control
+ voltage. On larger voltage decreases this can occur
+ undesiredly since the output voltage does not adjust
+ immediately to changes in the control voltage. To
+ avoid this situation the vctrl driver breaks down
+ larger voltage decreases into multiple steps, where
+ each step is within the OVP threshold.
+- min-slew-down-rate : Describes how slowly the regulator voltage will decay
+ down in the worst case (lightest expected load).
+ Specified in uV / us (like main regulator ramp rate).
+ This value is required when ovp-threshold-percent is
+ specified.
+
+Example:
+
+ vctrl-reg {
+ compatible = "vctrl-regulator";
+ regulator-name = "vctrl_reg";
+
+ ctrl-supply = <&ctrl_reg>;
+
+ regulator-min-microvolt = <800000>;
+ regulator-max-microvolt = <1500000>;
+
+ ctrl-voltage-range = <200000 500000>;
+
+ min-slew-down-rate = <225>;
+ ovp-threshold-percent = <16>;
+ };

+Versatile Express voltage regulators
+------------------------------------
+
+Requires node properties:
+- "compatible" value: "arm,vexpress-volt"
+- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
+ (see Documentation/devicetree/bindings/arm/vexpress-config.yaml
+ for more details)
+
+Required regulator properties:
+- "regulator-name"
+- "regulator-always-on"
+
+Optional regulator properties:
+- "regulator-min-microvolt"
+- "regulator-max-microvolt"
+
+See Documentation/devicetree/bindings/regulator/regulator.txt
+for more details about the regulator properties.
+
+When no "regulator-[min|max]-microvolt" properties are defined,
+the device is treated as fixed (or rather "read-only") regulator.
+
+Example:
+ volt@0 {
+ compatible = "arm,vexpress-volt";
+ arm,vexpress-sysreg,func = <2 0>;
+ regulator-name = "Cores";
+ regulator-min-microvolt = <800000>;

+ The firmware running on the processor inside the RPM subsystem allows each

+ clocks, regulators and bus frequencies. It implements multiple separate
+ communication interfaces that are described in subnodes, e.g. SMD and MPM:

+
+This binding provides support for adjunct processors found on ST SoCs.
+
+Co-processors can be controlled from the bootloader or the primary OS. If
+the bootloader starts a co-processor, the primary OS must detect its state
+and act accordingly.
+
+Required properties:
+- compatible Should be one of:
+ "st,st231-rproc"
+ "st,st40-rproc"
+- memory-region Reserved memory (See: ../reserved-memory/reserved-memory.txt)
+- resets Reset lines (See: ../reset/reset.txt)
+- reset-names Must be "sw_reset" and "pwr_reset"
+- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
+- clock-frequency Clock frequency to set co-processor at if the bootloader
+ hasn't already done so
+- st,syscfg System configuration register which holds the boot vector
+ for the co-processor
+ 1st cell: Phandle to syscon block

+TI Davinci DSP devices
+=======================
+
+Binding status: Unstable - Subject to changes for DT representation of clocks
+ and resets
+
+The TI Davinci family of SoCs usually contains a TI DSP Core sub-system that
+is used to offload some of the processor-intensive tasks or algorithms, for
+achieving various system level goals.
+
+The processor cores in the sub-system usually contain additional sub-modules
+like L1 and/or L2 caches/SRAMs, an Interrupt Controller, an external memory
+controller, a dedicated local power/sleep controller etc. The DSP processor
+core used in Davinci SoCs is usually a C674x DSP CPU.
+
+DSP Device Node:
+================
+Each DSP Core sub-system is represented as a single DT node.
+
+Required properties:
+--------------------
+The following are the mandatory properties:
+
+- compatible: Should be one of the following,
+ "ti,da850-dsp" for DSPs on OMAP-L138 SoCs
+
+- reg: Should contain an entry for each value in 'reg-names'.
+ Each entry should have the memory region's start address
+ and the size of the region, the representation matching
+ the parent node's '#address-cells' and '#size-cells' values.
+
+- reg-names: Should contain strings with the following names, each
+ representing a specific internal memory region or a
+ specific register space,
+ "l2sram", "l1pram", "l1dram", "host1cfg", "chipsig_base"
+
+- interrupts: Should contain the interrupt number used to receive the
+ interrupts from the DSP. The value should follow the
+ interrupt-specifier format as dictated by the
+ 'interrupt-parent' node.
+
+- memory-region: phandle to the reserved memory node to be associated
+ with the remoteproc device. The reserved memory node
+ can be a CMA memory node, and should be defined as
+ per the bindings in
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
+
+
+Example:
+--------
+
+ /* DSP Reserved Memory node */
+ reserved-memory {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ dsp_memory_region: dsp-memory@c3000000 {

+TI Keystone DSP devices
+=======================
+
+The TI Keystone 2 family of SoCs usually have one or more (upto 8) TI DSP Core
+sub-systems that are used to offload some of the processor-intensive tasks or
+algorithms, for achieving various system level goals.
+
+These processor sub-systems usually contain additional sub-modules like L1
+and/or L2 caches/SRAMs, an Interrupt Controller, an external memory controller,
+a dedicated local power/sleep controller etc. The DSP processor core in
+Keystone 2 SoCs is usually a TMS320C66x CorePac processor.
+
+DSP Device Node:
+================
+Each DSP Core sub-system is represented as a single DT node, and should also
+have an alias with the stem 'rproc' defined. Each node has a number of required
+or optional properties that enable the OS running on the host processor (ARM
+CorePac) to perform the device management of the remote processor and to
+communicate with the remote processor.
+
+Required properties:
+--------------------
+The following are the mandatory properties:
+
+- compatible: Should be one of the following,
+ "ti,k2hk-dsp" for DSPs on Keystone 2 66AK2H/K SoCs
+ "ti,k2l-dsp" for DSPs on Keystone 2 66AK2L SoCs
+ "ti,k2e-dsp" for DSPs on Keystone 2 66AK2E SoCs
+ "ti,k2g-dsp" for DSPs on Keystone 2 66AK2G SoCs
+
+- reg: Should contain an entry for each value in 'reg-names'.
+ Each entry should have the memory region's start address
+ and the size of the region, the representation matching
+ the parent node's '#address-cells' and '#size-cells' values.
+
+- reg-names: Should contain strings with the following names, each
+ representing a specific internal memory region, and
+ should be defined in this order,
+ "l2sram", "l1pram", "l1dram"
+
+- ti,syscon-dev: Should be a pair of the phandle to the Keystone Device
+ State Control node, and the register offset of the DSP
+ boot address register within that node's address space.
+
+- resets: Should contain the phandle to the reset controller node
+ managing the resets for this device, and a reset
+ specifier. Please refer to either of the following reset
+ bindings for the reset argument specifier as per SoC,
+ Documentation/devicetree/bindings/reset/ti-syscon-reset.txt
+ for 66AK2HK/66AK2L/66AK2E SoCs or,
+ Documentation/devicetree/bindings/reset/ti,sci-reset.yaml
+ for 66AK2G SoCs
+
+- interrupts: Should contain an entry for each value in 'interrupt-names'.
+ Each entry should have the interrupt source number used by
+ the remote processor to the host processor. The values should
+ follow the interrupt-specifier format as dictated by the
+ 'interrupt-parent' node. The purpose of each is as per the
+ description in the 'interrupt-names' property.
+
+- interrupt-names: Should contain strings with the following names, each
+ representing a specific interrupt,
+ "vring" - interrupt for virtio based IPC
+ "exception" - interrupt for exception notification
+
+- kick-gpios: Should specify the gpio device needed for the virtio IPC
+ stack. This will be used to interrupt the remote processor.
+ The gpio device to be used is as per the bindings in,
+ Documentation/devicetree/bindings/gpio/gpio-dsp-keystone.txt
+
+SoC-specific Required properties:
+---------------------------------
+The following are mandatory properties for Keystone 2 66AK2HK, 66AK2L and 66AK2E
+SoCs only:
+
+- clocks: Should contain the device's input clock, and should be
+ defined as per the bindings in,
+ Documentation/devicetree/bindings/clock/keystone-gate.txt
+
+The following are mandatory properties for Keystone 2 66AK2G SoCs only:
+
+- power-domains: Should contain a phandle to a PM domain provider node
+ and an args specifier containing the DSP device id
+ value. This property is as per the binding,
+ Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
+
+Optional properties:
+--------------------
+
+- memory-region: phandle to the reserved memory node to be associated
+ with the remoteproc device. The reserved memory node
+ can be a CMA memory node, and should be defined as
+ per the bindings in
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt

+description: |
+ Each Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS or PRUSS) has two 32-bit load/store RISC CPU cores called
+ Programmable Real-Time Units (PRUs), each represented by a node. Each PRU
+ core has a dedicated Instruction RAM, Control and Debug register sets, and
+ use the Data RAMs present within the PRU-ICSS for code execution.
+
+ The K3 SoCs containing ICSSG v1.0 (eg: AM65x SR1.0) also have two Auxiliary
+ PRU cores called RTUs with slightly different IP integration. The K3 SoCs
+ containing the revised ICSSG v1.1 (eg: J721E, AM65x SR2.0) have an extra two
+ auxiliary Transmit PRU cores called Tx_PRUs that augment the PRUs. Each RTU
+ or Tx_PRU core can also be used independently like a PRU, or alongside a
+ corresponding PRU core to provide/implement auxiliary functionality/support.
+
+ Each PRU, RTU or Tx_PRU core node should be defined as a child node of the
+ corresponding PRU-ICSS node. Each node can optionally be rendered inactive by
+ using the standard DT string property, "status".
+
+ Please see the overall PRU-ICSS bindings document for additional details
+ including a complete example,

+TI Wakeup M3 Remoteproc Driver
+==============================
+
+The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+that cannot be controlled from the MPU. This CM3 processor requires a firmware
+binary to accomplish this. The wkup_m3 remoteproc driver handles the loading of
+the firmware and booting of the CM3.
+
+Wkup M3 Device Node:
+====================
+A wkup_m3 device node is used to represent the Wakeup M3 processor instance
+within the SoC. It is added as a child node of the parent interconnect bus
+(l4_wkup) through which it is accessible to the MPU.
+
+Required properties:
+--------------------
+- compatible: Should be one of,
+ "ti,am3352-wkup-m3" for AM33xx SoCs
+ "ti,am4372-wkup-m3" for AM43xx SoCs
+- reg: Should contain the address ranges for the two internal
+ memory regions, UMEM and DMEM. The parent node should
+ provide an appropriate ranges property for properly
+ translating these into bus addresses.
+- reg-names: Contains the corresponding names for the two memory
+ regions. These should be named "umem" & "dmem".
+- ti,hwmods: Name of the hwmod associated with the wkupm3 device.
+- ti,pm-firmware: Name of firmware file to be used for loading and
+ booting the wkup_m3 remote processor.
+
+Example:
+--------
+/* AM33xx */
+ocp {
+ l4_wkup: l4_wkup@44c00000 {
+ compatible = "am335-l4-wkup", "simple-bus";
+ ranges = <0 0x44c00000 0x400000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+

+ compatible = "ti,am3352-wkup-m3";
+ reg = <0x100000 0x4000>,
+ <0x180000 0x2000>;
+ reg-names = "umem", "dmem";
+ ti,hwmods = "wkup_m3";
+ ti,pm-firmware = "am335x-pm-firmware.elf";

+ create child nodes describing particular reserved (excluded from normal use)
+ memory regions. Such memory regions are usually designed for the special

+

+ optional constraints to request a dynamically allocated block of
+ memory.
+
+ Following the generic-names recommended practice, node names should
+ reflect the purpose of the node (ie. "framebuffer" or "dma-pool").
+ Unit address (@<address>) should be appended to the name if the node
+ is a static allocation.

+Pistachio Reset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable individual IP blocks within the Pistachio SoC using "soft reset"
+control bits found in the Pistachio SoC top level registers.
+
+The actual action taken when soft reset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers, and following an assert/deassert sequence the hardware's previous
+state may no longer be valid.
+
+Please refer to Documentation/devicetree/bindings/reset/reset.txt
+for common reset controller binding usage.
+
+Required properties:
+
+- compatible: Contains "img,pistachio-reset"
+
+- #reset-cells: Contains 1
+
+Example:
+
+ cr_periph: clk@18148000 {
+ compatible = "img,pistachio-cr-periph", "syscon", "simple-mfd";
+ reg = <0x18148000 0x1000>;
+ clocks = <&clk_periph PERIPH_CLK_SYS>;
+ clock-names = "sys";
+ #clock-cells = <1>;
+
+ pistachio_reset: reset-controller {
+ compatible = "img,pistachio-reset";
+ #reset-cells = <1>;
+ };
+ };
+
+Specifying reset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the pistachio reset device node and an
+index specifying which reset to use, as described in
+Documentation/devicetree/bindings/reset/reset.txt.
+
+Example:
+
+ spdif_out: spdif-out@18100d00 {
+ ...
+ resets = <&pistachio_reset PISTACHIO_RESET_SPDIF_OUT>;
+ reset-names = "rst";
+ ...
+ };
+
+Macro definitions for the supported resets can be found in:
+include/dt-bindings/reset/pistachio-resets.h

+= Reset Signal Device Tree Bindings =
+
+This binding is intended to represent the hardware reset signals present
+internally in most IC (SoC, FPGA, ...) designs. Reset signals for whole
+standalone chips are most likely better represented as GPIOs, although there
+are likely to be exceptions to this rule.
+
+Hardware blocks typically receive a reset signal. This signal is generated by
+a reset provider (e.g. power management or clock module) and received by a
+reset consumer (the module being reset, or a module managing when a sub-
+ordinate module is reset). This binding exists to represent the provider and
+consumer, and provide a way to couple the two together.
+
+A reset signal is represented by the phandle of the provider, plus a reset
+specifier - a list of DT cells that represents the reset signal within the
+provider. The length (number of cells) and semantics of the reset specifier
+are dictated by the binding of the reset provider, although common schemes
+are described below.
+
+A word on where to place reset signal consumers in device tree: It is possible
+in hardware for a reset signal to affect multiple logically separate HW blocks
+at once. In this case, it would be unwise to represent this reset signal in
+the DT node of each affected HW block, since if activated, an unrelated block
+may be reset. Instead, reset signals should be represented in the DT node
+where it makes most sense to control it; this may be a bus node if all
+children of the bus are affected by the reset signal, or an individual HW
+block node for dedicated reset signals. The intent of this binding is to give
+appropriate software access to the reset signals in order to manage the HW,
+rather than to slavishly enumerate the reset signal that affects each HW
+block.
+
+= Reset providers =
+
+Required properties:
+#reset-cells: Number of cells in a reset specifier; Typically 0 for nodes
+ with a single reset output and 1 for nodes with multiple
+ reset outputs.
+
+For example:
+
+ rst: reset-controller {
+ #reset-cells = <1>;
+ };
+
+= Reset consumers =
+
+Required properties:
+resets: List of phandle and reset specifier pairs, one pair
+ for each reset signal that affects the device, or that the
+ device manages. Note: if the reset provider specifies '0' for
+ #reset-cells, then only the phandle portion of the pair will
+ appear.
+
+Optional properties:
+reset-names: List of reset signal name strings sorted in the same order as
+ the resets property. Consumers drivers will use reset-names to
+ match reset signal names with reset specifiers.
+
+For example:
+
+ device {
+ resets = <&rst 20>;
+ reset-names = "reset";
+ };
+
+This represents a device with a single reset signal named "reset".
+
+ bus {
+ resets = <&rst 10> <&rst 11> <&rst 12> <&rst 11>;
+ reset-names = "i2s1", "i2s2", "dma", "mixer";
+ };
+
+This represents a bus that controls the reset signal of each of four sub-
+ordinate devices. Consider for example a bus that fails to operate unless no
+child device has reset asserted.

+STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable on-chip peripheral controllers such as USB and SATA, using
+"softreset" control bits found in the STi family SoC system configuration
+registers.
+
+The actual action taken when softreset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers and after an assert/deassert sequence the hardware's previous state
+may no longer be valid.
+
+Please refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,stih407-softreset";
+- #reset-cells: 1, see below
+
+example:
+
+ softreset: softreset-controller {
+ #reset-cells = <1>;
+ compatible = "st,stih407-softreset";
+ };
+
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the softreset device node and an
+index specifying which channel to use, as described in reset.txt
+
+example:
+
+ ethernet0{
+ resets = <&softreset STIH415_ETH0_SOFTRESET>;
+ };

+TI SysCon Reset Controller
+=======================
+
+Almost all SoCs have hardware modules that require reset control in addition
+to clock and power control for their functionality. The reset control is
+typically provided by means of memory-mapped I/O registers. These registers are
+sometimes a part of a larger register space region implementing various
+functionalities. This register range is best represented as a syscon node to
+allow multiple entities to access their relevant registers in the common
+register space.
+
+A SysCon Reset Controller node defines a device that uses a syscon node
+and provides reset management functionality for various hardware modules
+present on the SoC.
+
+SysCon Reset Controller Node
+============================
+Each of the reset provider/controller nodes should be a child of a syscon
+node and have the following properties.
+
+Required properties:
+--------------------
+ - compatible : Should be,
+ "ti,k2e-pscrst"
+ "ti,k2l-pscrst"
+ "ti,k2hk-pscrst"
+ "ti,syscon-reset"
+ - #reset-cells : Should be 1. Please see the reset consumer node below
+ for usage details
+ - ti,reset-bits : Contains the reset control register information
+ Should contain 7 cells for each reset exposed to
+ consumers, defined as:
+ Cell #1 : offset of the reset assert control
+ register from the syscon register base
+ Cell #2 : bit position of the reset in the reset
+ assert control register
+ Cell #3 : offset of the reset deassert control
+ register from the syscon register base
+ Cell #4 : bit position of the reset in the reset
+ deassert control register
+ Cell #5 : offset of the reset status register
+ from the syscon register base
+ Cell #6 : bit position of the reset in the
+ reset status register
+ Cell #7 : Flags used to control reset behavior,
+ available flags defined in the DT include
+ file <dt-bindings/reset/ti-syscon.h>
+
+SysCon Reset Consumer Nodes
+===========================
+Each of the reset consumer nodes should have the following properties,
+in addition to their own properties.
+
+Required properties:
+--------------------
+ - resets : A phandle to the reset controller node and an index number
+ to a reset specifier as defined above.
+
+Please also refer to Documentation/devicetree/bindings/reset/reset.txt for
+common reset controller usage by consumers.
+
+Example:
+--------
+The following example demonstrates a syscon node, the reset controller node
+using the syscon node, and a consumer (a DSP device) on the TI Keystone 2
+66AK2E SoC.
+
+/ {
+ soc {
+ psc: power-sleep-controller@2350000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x02350000 0x1000>;
+
+ pscrst: reset-controller {
+ compatible = "ti,k2e-pscrst", "ti,syscon-reset";
+ #reset-cells = <1>;
+
+ ti,reset-bits = <
+ 0xa3c 8 0xa3c 8 0x83c 8 (ASSERT_CLEAR | DEASSERT_SET | STATUS_CLEAR) /* 0: dsp0 */
+ 0xa40 5 0xa44 3 0 0 (ASSERT_SET | DEASSERT_CLEAR | STATUS_NONE) /* 1: example */
+ >;
+ };
+ };
+
+ dsp0: dsp0 {
+ ...
+ resets = <&pscrst 0>;
+ ...
+ };
+ };
+};

+description: |
+ RISC-V has a large number of extensions, some of which are "standard"
+ extensions, meaning they are ratified by RISC-V International, and others
+ are "vendor" extensions.
+ This document defines properties that indicate whether a hart supports a
+ given extension.
+
+ Once a standard extension has been ratified, no changes in behaviour can be
+ made without the creation of a new extension.
+ The properties for standard extensions therefore map to their originally
+ ratified states, with the exception of the I, Zicntr & Zihpm extensions.
+ See the "i" property for more information.

+ User-Level ISA document, available from
+ https://riscv.org/specifications/
+
+ Due to revisions of the ISA specification, some deviations
+ have arisen over time.
+ Notably, riscv,isa was defined prior to the creation of the
+ Zicntr, Zicsr, Zifencei and Zihpm extensions and thus "i"
+ implies "zicntr_zicsr_zifencei_zihpm".
+
+ While the isa strings in ISA specification are case
+ insensitive, letters in the riscv,isa string must be all
+ lowercase.

+ an alarm time (in seconds) is to be written.
+ The alarm register is a simple scratch register shared between the
+ application processors (AP) and the secure co-processor (SCP.) When
+ the AP suspends, the SCP will use the value of this register to
+ program an always-on timer before going sleep. When the timer expires,
+ the SCP will wake up and will then wake the AP.

+Intersil ISL12057 I2C RTC/Alarm chip
+
+ISL12057 is a trivial I2C device (it has simple device tree bindings,
+consisting of a compatible field, an address and possibly an interrupt
+line).
+
+Nonetheless, it also supports an option boolean property
+("wakeup-source") to handle the specific use-case found
+on at least three in-tree users of the chip (NETGEAR ReadyNAS 102, 104
+and 2120 ARM-based NAS); On those devices, the IRQ#2 pin of the chip
+(associated with the alarm supported by the driver) is not connected
+to the SoC but to a PMIC. It allows the device to be powered up when
+RTC alarm rings. In order to mark the device has a wakeup source and
+get access to the 'wakealarm' sysfs entry, this specific property can
+be set when the IRQ#2 pin of the chip is not connected to the SoC but
+can wake up the device.
+
+Required properties supported by the device:
+
+ - "compatible": must be "isil,isl12057"
+ - "reg": I2C bus address of the device
+
+Optional properties:
+
+ - "wakeup-source": mark the chip as a wakeup source, independently of
+ the availability of an IRQ line connected to the SoC.
+
+
+Example isl12057 node without IRQ#2 pin connected (no alarm support):
+
+ isl12057: isl12057@68 {
+ compatible = "isil,isl12057";
+ reg = <0x68>;
+ };
+
+
+Example isl12057 node with IRQ#2 pin connected to main SoC via MPP6 (note
+that the pinctrl-related properties below are given for completeness and
+may not be required or may be different depending on your system or
+SoC, and the main function of the MPP used as IRQ line, i.e.
+"interrupt-parent" and "interrupts" are usually sufficient):
+
+ pinctrl {
+ ...
+
+ rtc_alarm_pin: rtc_alarm_pin {
+ marvell,pins = "mpp6";
+ marvell,function = "gpio";
+ };
+
+ ...
+
+ };
+

+
+ isl12057: isl12057@68 {

+ pinctrl-0 = <&rtc_alarm_pin>;
+ pinctrl-names = "default";
+ interrupt-parent = <&gpio0>;
+ interrupts = <6 IRQ_TYPE_EDGE_FALLING>;
+ };
+
+
+Example isl12057 node without IRQ#2 pin connected to the SoC but to a
+PMIC, allowing the device to be started based on configured alarm:
+
+ isl12057: isl12057@68 {
+ compatible = "isil,isl12057";
+ reg = <0x68>;
+ wakeup-source;

+* Maxim/Dallas Semiconductor DS-1302 RTC
+
+Simple device which could be used to store date/time between reboots.
+
+The device uses the standard MicroWire half-duplex transfer timing.
+Master output is set on low clock and sensed by the RTC on the rising
+edge. Master input is set by the RTC on the trailing edge and is sensed
+by the master on low clock.
+
+Required properties:
+
+- compatible : Should be "maxim,ds1302"
+
+Required SPI properties:
+
+- reg : Should be address of the device chip select within
+ the controller.
+
+- spi-max-frequency : DS-1302 has 500 kHz if powered at 2.2V,
+ and 2MHz if powered at 5V.
+
+- spi-3wire : The device has a shared signal IN/OUT line.
+
+- spi-lsb-first : DS-1302 requires least significant bit first
+ transfers.
+
+- spi-cs-high: DS-1302 has active high chip select line. This is
+ required unless inverted in hardware.

+Palmas RTC controller bindings
+
+Required properties:
+- compatible:
+ - "ti,palmas-rtc" for palma series of the RTC controller
+- interrupts: Interrupt number of RTC submodule on device.
+
+Optional properties:
+
+- ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
+ TPS80036 supports the backup battery for powering the RTC when main
+ battery is removed or in very low power state. The backup battery
+ can be chargeable or non-chargeable. This flag will tells whether
+ battery is chargeable or not. If charging battery then driver can
+ enable the charging.
+- ti,backup-battery-charge-high-current: Enable high current charging in
+ backup battery. Device supports the < 100uA and > 100uA charging.
+ The high current will be > 100uA. Absence of this property will
+ charge battery to lower current i.e. < 100uA.
+
+Example:
+ palmas: tps65913@58 {
+ ...
+ palmas_rtc: rtc {
+ compatible = "ti,palmas-rtc";
+ interrupt-parent = <&palmas>;
+ interrupts = <8 0>;

+
+LPC currently supports Watchdog OR Real Time Clock OR Clocksource
+functionality.
+
+[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
+[See: ../timer/st,stih407-lpc for Clocksource options]
+
+Required properties
+
+- compatible : Must be: "st,stih407-lpc"
+- reg : LPC registers base address + size
+- interrupts : LPC interrupt line number and associated flags
+- clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
+- st,lpc-mode : The LPC can run either one of three modes:
+ ST_LPC_MODE_RTC [0]
+ ST_LPC_MODE_WDT [1]
+ ST_LPC_MODE_CLKSRC [2]
+ One (and only one) mode must be selected.
+
+Example:
+ lpc@fde05000 {
+ compatible = "st,stih407-lpc";
+ reg = <0xfde05000 0x1000>;
+ clocks = <&clk_s_d3_flexgen CLK_LPC_0>;

+ (c) "hisilicon,hip07-sas-v2" for v2 hw in hip07 chipset
+ - sas-addr : array of 8 bytes for host SAS address
+ - reg : Contains two regions. The first is the address and length of the SAS
+ register. The second is the address and length of CPLD register for
+ SGPIO control. The second is optional, and should be set only when
+ we use a CPLD for directly attached disk LED control.
+ - hisilicon,sas-syscon: phandle of syscon used for sas control
+ - ctrl-reset-reg : offset to controller reset register in ctrl reg
+ - ctrl-reset-sts-reg : offset to controller reset status register in ctrl reg
+ - ctrl-clock-ena-reg : offset to controller clock enable register in ctrl reg
+ - queue-count : number of delivery and completion queues in the controller
+ - phy-count : number of phys accessible by the controller
+ - interrupts : For v1 hw: Interrupts for phys, completion queues, and fatal
+ sources; the interrupts are ordered in 3 groups, as follows:
+ - Phy interrupts
+ - Completion queue interrupts
+ - Fatal interrupts
+ Phy interrupts : Each phy has 3 interrupt sources:
+ - broadcast
+ - phyup
+ - abnormal
+ The phy interrupts are ordered into groups of 3 per phy
+ (broadcast, phyup, and abnormal) in increasing order.
+ Completion queue interrupts : each completion queue has 1
+ interrupt source.
+ The interrupts are ordered in increasing order.
+ Fatal interrupts : the fatal interrupts are ordered as follows:
+ - ECC
+ - AXI bus
+ For v2 hw: Interrupts for phys, Sata, and completion queues;
+ the interrupts are ordered in 3 groups, as follows:
+ - Phy interrupts
+ - Sata interrupts
+ - Completion queue interrupts
+ Phy interrupts : Each controller has 2 phy interrupts:
+ - phy up/down
+ - channel interrupt
+ Sata interrupts : Each phy on the controller has 1 Sata
+ interrupt. The interrupts are ordered in increasing
+ order.
+ Completion queue interrupts : each completion queue has 1
+ interrupt source. The interrupts are ordered in
+ increasing order.
+
+Optional main node properties:
+ - hip06-sas-v2-quirk-amt : when set, indicates that the v2 controller has the
+ "am-max-transmissions" limitation.
+ - hisilicon,signal-attenuation : array of 3 32-bit values, containing de-emphasis,
+ preshoot, and boost attenuation readings for the board. They
+ are used to describe the signal attenuation of the board. These
+ values' range is 7600 to 12400, and used to represent -24dB to

+* Marvell UART : Non standard UART used in some of Marvell EBU SoCs
+ e.g., Armada-3700.
+
+Required properties:
+- compatible:
+ - "marvell,armada-3700-uart" for the standard variant of the UART
+ (32 bytes FIFO, no DMA, level interrupts, 8-bit access to the
+ FIFO), called also UART1.
+ - "marvell,armada-3700-uart-ext" for the extended variant of the
+ UART (128 bytes FIFO, DMA, front interrupts, 8-bit or 32-bit
+ accesses to the FIFO), called also UART2.
+- reg: offset and length of the register set for the device.
+- clocks: UART reference clock used to derive the baudrate. If no clock
+ is provided (possible only with the "marvell,armada-3700-uart"
+ compatible string for backward compatibility), it will only work
+ if the baudrate was initialized by the bootloader and no baudrate
+ change will then be possible. When provided it should be UART1-clk
+ for standard variant of UART and UART2-clk for extended variant
+ of UART. TBG clock (with UART TBG divisors d1=d2=1) or xtal clock
+ should not be used and are supported only for backward compatibility.
+- interrupts:
+ - Must contain three elements for the standard variant of the IP
+ (marvell,armada-3700-uart): "uart-sum", "uart-tx" and "uart-rx",
+ respectively the UART sum interrupt, the UART TX interrupt and
+ UART RX interrupt. A corresponding interrupt-names property must
+ be defined.
+ - Must contain two elements for the extended variant of the IP
+ (marvell,armada-3700-uart-ext): "uart-tx" and "uart-rx",
+ respectively the UART TX interrupt and the UART RX interrupt. A
+ corresponding interrupt-names property must be defined.
+ - For backward compatibility reasons, a single element interrupts
+ property is also supported for the standard variant of the IP,
+ containing only the UART sum interrupt. This form is deprecated
+ and should no longer be used.
+
+Example:
+ uart0: serial@12000 {
+ compatible = "marvell,armada-3700-uart";
+ reg = <0x12000 0x18>;
+ clocks = <&uartclk 0>;

+description:
+ The TCU is a system for sharing a hardware UART instance among multiple
+ systems within the Tegra SoC. It is implemented through a mailbox-
+ based protocol where each "virtual UART" has a pair of mailboxes, one
+ for transmitting and one for receiving, that is used to communicate
+ with the hardware implementing the TCU.

+ controller falls within the range mentioned in this field, the baud rate will be adjusted by
+ percentage mentioned here.
+
+ Example: <9600 115200 200>
+
+ Increase baud rate by 2% when set baud rate falls within range 9600 to 115200.
+
+ Standard UART devices are expected to have tolerance for baud rate error by -4 to +4 %. All
+ Tegra devices till Tegra210 had this support. However, Tegra186 chip has a known hardware
+ issue. UART RX baud rate tolerance level is 0% to +4% in 1-stop config. Otherwise, the
+ received data will have corruption/invalid framing errors. Parker errata suggests adjusting
+ baud rate to be higher than the deviations observed in TX.
+
+ TX deviation of connected device can be captured over scope (or noted from its spec) for
+ valid range and Tegra baud rate has to be set above actual TX baud rate observed. To do this
+ we use nvidia,adjust-baud-rates.
+
+ As an example, consider there is deviation observed in TX for baud rates as listed below. 0
+ to 9600 has 1% deviation 9600 to 115200 2% deviation. This slight deviation is expcted and
+ Tegra UART is expected to handle it. Due to the issue stated above, baud rate on Tegra UART
+ should be set equal to or above deviation observed for avoiding frame errors. Property
+ should be set like this:
+
+ nvidia,adjust-baud-rates = <0 9600 100>,
+ <9600 115200 200>;

+DT compatible string versioning for SiFive open-source IP blocks
+
+This document describes the version specification for DT "compatible"
+strings for open-source SiFive IP blocks. HDL for these IP blocks
+can be found in this public repository:
+
+https://github.com/sifive/sifive-blocks
+
+IP block-specific DT compatible strings are contained within the HDL,
+in the form "sifive,<ip-block-name><integer version number>".
+
+An example is "sifive,uart0" from:
+
+https://github.com/sifive/sifive-blocks/blob/v1.0/src/main/scala/devices/uart/UART.scala#L43
+
+Until these IP blocks (or IP integration) support version
+auto-discovery, the maintainers of these IP blocks intend to increment
+the suffixed number in the compatible string whenever the software
+interface to these IP blocks changes, or when the functionality of the
+underlying IP blocks changes in a way that software should be aware of.
+
+Driver developers can use compatible string "match" values such as
+"sifive,uart0" to indicate that their driver is compatible with the
+register interface and functionality associated with the relevant
+upstream sifive-blocks commits. It is expected that most drivers will
+match on these IP block-specific compatible strings.
+
+DT data authors, when writing data for a particular SoC, should
+continue to specify an SoC-specific compatible string value, such as
+"sifive,fu540-c000-uart". This way, if SoC-specific
+integration-specific bug fixes or workarounds are needed, the kernel
+or other system software can match on this string to apply them. The
+IP block-specific compatible string (such as "sifive,uart0") should
+then be specified as a subsequent value.
+
+An example of this style:
+
+ compatible = "sifive,fu540-c000-uart", "sifive,uart0";

+description:
+ The Aspeed UART routing control allow to dynamically route the inputs for
+ the built-in UARTS and physical serial I/O ports.
+
+ This allows, for example, to connect the output of UART to another UART.
+ This can be used to enable Host <-> BMC communication via UARTs, e.g. to
+ allow access to the Host's serial console.
+
+ This driver is for the BMC side. The sysfs files allow the BMC userspace
+ which owns the system configuration policy, to configure how UARTs and
+ physical serial I/O ports are routed.

+
+The Buffer Manager is part of the Data-Path Acceleration Architecture (DPAA).
+BMan supports hardware allocation and deallocation of buffers belonging to pools
+originally created by software with configurable depletion thresholds. This
+binding covers the CCSR space programming model

+BMan Private Memory Node
+
+BMan requires a contiguous range of physical memory used for the backing store
+for BMan Free Buffer Proxy Records (FBPR). This memory is reserved/allocated as
+a node under the /reserved-memory node.
+
+The BMan FBPR memory node must be named "bman-fbpr"
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: PPC platforms: Must include "fsl,bman-fbpr"
+ ARM platforms: Must include "shared-dma-pool"
+ as well as the "no-map" property
+
+The following constraints are relevant to the FBPR private memory:
+ - The size must be 2^(size + 1), with size = 11..33. That is 4 KiB to
+ 16 GiB
+ - The alignment must be a muliptle of the memory size
+
+The size of the FBPR must be chosen by observing the hardware features configured
+via the Reset Configuration Word (RCW) and that are relevant to a specific board
+(e.g. number of MAC(s) pinned-out, number of offline/host command FMan ports,
+etc.). The size configured in the DT must reflect the hardware capabilities and
+not the specific needs of an application
+
+For additional details about reserved memory regions see reserved-memory.txt
+
+EXAMPLE
+
+The example below shows a BMan FBPR dynamic allocation memory node
+
+ reserved-memory {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ ranges;
+
+ bman_fbpr: bman-fbpr {
+ compatible = "shared-mem-pool";
+ size = <0 0x1000000>;
+ alignment = <0 0x1000000>;
+ no-map;
+ };

+* Freescale Communications Processor Module
+
+NOTE: This is an interim binding, and will likely change slightly,
+as more devices are supported. The QE bindings especially are
+incomplete.
+
+* Root CPM node
+
+Properties:
+- compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
+- reg : A 48-byte region beginning with CPCR.
+
+Example:
+ cpm@119c0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ compatible = "fsl,mpc8272-cpm", "fsl,cpm2";
+ reg = <119c0 30>;
+ }
+
+* Properties common to multiple CPM/QE devices
+
+- fsl,cpm-command : This value is ORed with the opcode and command flag
+ to specify the device on which a CPM command operates.
+
+- fsl,cpm-brg : Indicates which baud rate generator the device
+ is associated with. If absent, an unused BRG
+ should be dynamically allocated. If zero, the
+ device uses an external clock rather than a BRG.
+
+- reg : Unless otherwise specified, the first resource represents the
+ scc/fcc/ucc registers, and the second represents the device's
+ parameter RAM region (if it has one).
+
+* Multi-User RAM (MURAM)
+
+The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+Ranges must be set up subject to the following restrictions:
+
+- Children's reg nodes must be offsets from the start of all muram, even
+ if the user-data area does not begin at zero.
+- If multiple range entries are used, the difference between the parent
+ address and the child address must be the same in all, so that a single
+ mapping can cover them all while maintaining the ability to determine
+ CPM-side offsets with pointer subtraction. It is recommended that
+ multiple range entries not be used.
+- A child address of zero must be translatable, even if no reg resources
+ contain it.
+
+A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+indicate the portion of muram that is usable by the OS for arbitrary
+purposes. The data node may have an arbitrary number of reg resources,
+all of which contribute to the allocatable muram pool.
+
+Example, based on mpc8272:
+ muram@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0 10000>;
+
+ data@0 {
+ compatible = "fsl,cpm-muram-data";
+ reg = <0 2000 9800 800>;
+ };

+* I2C
+
+The I2C controller is expressed as a bus under the CPM node.
+
+Properties:
+- compatible : "fsl,cpm1-i2c", "fsl,cpm2-i2c"
+- reg : On CPM2 devices, the second resource doesn't specify the I2C
+ Parameter RAM itself, but the I2C_BASE field of the CPM2 Parameter RAM
+ (typically 0x8afc 0x2).
+- #address-cells : Should be one. The cell is the i2c device address with
+ the r/w bit set to zero.
+- #size-cells : Should be zero.
+- clock-frequency : Can be used to set the i2c clock frequency. If
+ unspecified, a default frequency of 60kHz is being used.
+The following two properties are deprecated. They are only used by legacy
+i2c drivers to find the bus to probe:
+- linux,i2c-index : Can be used to hard code an i2c bus number. By default,
+ the bus number is dynamically assigned by the i2c core.
+- linux,i2c-class : Can be used to override the i2c class. The class is used
+ by legacy i2c device drivers to find a bus in a specific context like
+ system management, video or sound. By default, I2C_CLASS_HWMON (1) is
+ being used. The definition of the classes can be found in
+ include/i2c/i2c.h

+Every GPIO controller node must have #gpio-cells property defined,
+this information will be used to translate gpio-specifiers.
+
+On CPM1 devices, all ports are using slightly different register layouts.
+Ports A, C and D are 16bit ports and Ports B and E are 32bit ports.
+
+On CPM2 devices, all ports are 32bit ports and use a common register layout.
+
+Required properties:
+- compatible : "fsl,cpm1-pario-bank-a", "fsl,cpm1-pario-bank-b",
+ "fsl,cpm1-pario-bank-c", "fsl,cpm1-pario-bank-d",
+ "fsl,cpm1-pario-bank-e", "fsl,cpm2-pario-bank"
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+- gpio-controller : Marks the port as GPIO controller.
+Optional properties:
+- fsl,cpm1-gpio-irq-mask : For banks having interrupt capability (like port C
+ on CPM1), this item tells which ports have an associated interrupt (ports are
+ listed in the same order as in PCINT register)
+- interrupts : This property provides the list of interrupt for each GPIO having
+ one as described by the fsl,cpm1-gpio-irq-mask property. There should be as
+ many interrupts as number of ones in the mask property. The first interrupt in
+ the list corresponds to the most significant bit of the mask.
+

+
+ CPM1_PIO_A: gpio-controller@950 {
+ #gpio-cells = <2>;
+ compatible = "fsl,cpm1-pario-bank-a";

+* Freescale QUICC Engine module (QE)
+This represents qe module that is installed on PowerQUICC II Pro.
+
+NOTE: This is an interim binding; it should be updated to fit
+in with the CPM binding later in this document.
+
+Basically, it is a bus of devices, that could act more or less
+as a complete entity (UCC, USB etc ). All of them should be siblings on
+the "root" qe node, using the common properties from there.
+The description below applies to the qe of MPC8360 and
+more nodes and properties would be extended in the future.
+
+i) Root QE device
+
+Required properties:
+- compatible : should be "fsl,qe";
+- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
+- reg : offset and length of the device registers.
+- bus-frequency : the clock frequency for QUICC Engine.
+- fsl,qe-num-riscs: define how many RISC engines the QE has.
+- fsl,qe-snums: This property has to be specified as '/bits/ 8' value,
+ defining the array of serial number (SNUM) values for the virtual
+ threads.
+
+Optional properties:
+- fsl,firmware-phandle:
+ Usage: required only if there is no fsl,qe-firmware child node
+ Value type: <phandle>
+ Definition: Points to a firmware node (see "QE Firmware Node" below)
+ that contains the firmware that should be uploaded for this QE.
+ The compatible property for the firmware node should say,
+ "fsl,qe-firmware".
+
+Recommended properties
+- brg-frequency : the internal clock source frequency for baud-rate
+ generators in Hz.
+
+Deprecated properties
+- fsl,qe-num-snums: define how many serial number(SNUM) the QE can use
+ for the threads. Use fsl,qe-snums instead to not only specify the
+ number of snums, but also their values.
+
+Example:
+ qe@e0100000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ compatible = "fsl,qe";
+ ranges = <0 e0100000 00100000>;
+ reg = <e0100000 480>;
+ brg-frequency = <0>;
+ bus-frequency = <179A7B00>;
+ fsl,qe-snums = /bits/ 8 <
+ 0x04 0x05 0x0C 0x0D 0x14 0x15 0x1C 0x1D
+ 0x24 0x25 0x2C 0x2D 0x34 0x35 0x88 0x89
+ 0x98 0x99 0xA8 0xA9 0xB8 0xB9 0xC8 0xC9

+ }
+
+* Multi-User RAM (MURAM)
+
+Required properties:
+- compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
+- mode : the could be "host" or "slave".
+- ranges : Should be defined as specified in 1) to describe the

+- data-only : sub-node which defines the address area under MURAM
+ bus that can be allocated as data/parameter
+
+Example:
+
+ muram@10000 {
+ compatible = "fsl,qe-muram", "fsl,cpm-muram";
+ ranges = <0 00010000 0000c000>;
+
+ data-only@0{
+ compatible = "fsl,qe-muram-data",
+ "fsl,cpm-muram-data";
+ reg = <0 c000>;

+
+Required properties:
+- compatible : should be "fsl,qe-ic".

+* Serial Interface Block (SI)
+
+The SI manages the routing of eight TDM lines to the QE block serial drivers
+, the MCC and the UCCs, for receive and transmit.
+
+Required properties:
+- compatible : must be "fsl,<chip>-qe-si". For t1040, must contain
+ "fsl,t1040-qe-si".
+- reg : Address range of SI register set.
+
+Example:
+
+ si1: si@700 {
+ compatible = "fsl,t1040-qe-si";
+ reg = <0x700 0x80>;
+ };
+
+* Serial Interface Block RAM(SIRAM)
+
+store the routing entries of SI
+
+Required properties:
+- compatible : should be "fsl,<chip>-qe-siram". For t1040, must contain
+ "fsl,t1040-qe-siram".
+- reg : Address range of SI RAM.
+
+Example:
+
+ siram1: siram@1000 {
+ compatible = "fsl,t1040-qe-siram";
+ reg = <0x1000 0x800>;
+ };
+
+* QE Firmware Node
+
+This node defines a firmware binary that is embedded in the device tree, for
+the purpose of passing the firmware from bootloader to the kernel, or from
+the hypervisor to the guest.
+
+The firmware node itself contains the firmware binary contents, a compatible
+property, and any firmware-specific properties. The node should be placed
+inside a QE node that needs it. Doing so eliminates the need for a
+fsl,firmware-phandle property. Other QE nodes that need the same firmware
+should define an fsl,firmware-phandle property that points to the firmware node
+in the first QE node.
+
+The fsl,firmware property can be specified in the DTS (possibly using incbin)
+or can be inserted by the boot loader at boot time.
+
+Required properties:
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: A standard property. Specify a string that indicates what
+ kind of firmware it is. For QE, this should be "fsl,qe-firmware".
+
+ - fsl,firmware
+ Usage: required
+ Value type: <prop-encoded-array>, encoded as an array of bytes
+ Definition: A standard property. This property contains the firmware
+ binary "blob".
+
+Example:
+ qe1@e0080000 {
+ compatible = "fsl,qe";
+ qe_firmware:qe-firmware {
+ compatible = "fsl,qe-firmware";
+ fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
+ };
+ ...
+ };
+
+ qe2@e0090000 {
+ compatible = "fsl,qe";
+ fsl,firmware-phandle = <&qe_firmware>;
+ ...
+ };

+* Uploaded QE firmware
+
+ If a new firmware has been uploaded to the QE (usually by the
+ boot loader), then a 'firmware' child node should be added to the QE
+ node. This node provides information on the uploaded firmware that
+ device drivers may need.
+
+ Required properties:
+ - id: The string name of the firmware. This is taken from the 'id'
+ member of the qe_firmware structure of the uploaded firmware.
+ Device drivers can search this string to determine if the
+ firmware they want is already present.
+ - extended-modes: The Extended Modes bitfield, taken from the
+ firmware binary. It is a 64-bit number represented
+ as an array of two 32-bit numbers.

+This node configures Parallel I/O ports for CPUs with QE support.
+The node should reside in the "soc" node of the tree. For each
+device that using parallel I/O ports, a child node should be created.
+See the definition of the Pin configuration nodes below for more
+information.
+
+Required properties:
+- device_type : should be "par_io".
+- reg : offset to the register set and its length.
+- num-ports : number of Parallel I/O ports

+ #size-cells = <0>;
+ device_type = "par_io";
+ num-ports = <7>;
+ ucc_pin@1 {
+ ......
+ };
+
+Note that "par_io" nodes are obsolete, and should not be used for
+the new device trees. Instead, each Par I/O bank should be represented
+via its own gpio-controller node:
+
+Required properties:
+- #gpio-cells : should be "2".
+- compatible : should be "fsl,<chip>-qe-pario-bank",
+ "fsl,mpc8323-qe-pario-bank".
+- reg : offset to the register set and its length.

+ open_drain, assignment, has_irq.
+ - port : port number of the pin; 0-6 represent port A-G in UM.
+ - pin : pin number in the port.
+ - dir : direction of the pin, should encode as follows:
+
+ 0 = The pin is disabled
+ 1 = The pin is an output
+ 2 = The pin is an input
+ 3 = The pin is I/O
+
+ - open_drain : indicates the pin is normal or wired-OR:

+ 0 = The pin is actively driven as an output
+ 1 = The pin is an open-drain driver. As an output, the pin is
+ driven active-low, otherwise it is three-stated.
+
+ - assignment : function number of the pin according to the Pin Assignment
+ tables in User Manual. Each pin can have up to 4 possible functions in
+ QE and two options for CPM.

+- compatible : could be "ucc_geth" or "fsl_atm" and so on.
+- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
+- reg : Offset and length of the register set for the device
+- interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+- pio-handle : The phandle for the Parallel I/O port configuration.
+- port-number : for UART drivers, the port number to use, between 0 and 3.
+ This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
+ The port number is added to the minor number of the device. Unlike the
+ CPM UART driver, the port-number is required for the QE UART driver.
+- soft-uart : for UART drivers, if specified this means the QE UART device
+ driver should use "Soft-UART" mode, which is needed on some SOCs that have
+ broken UART hardware. Soft-UART is provided via a microcode upload.
+- rx-clock-name: the UCC receive clock source
+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively

+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+The following two properties are deprecated. rx-clock has been replaced
+with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
+Drivers that currently use the deprecated properties should continue to
+do so, in order to support older device trees, but they should be updated
+to check for the new properties first.
+- rx-clock : represents the UCC receive clock source.
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+- tx-clock: represents the UCC transmit clock source;
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+
+Required properties for network device_type:
+- mac-address : list of bytes representing the ethernet address.
+- phy-handle : The phandle for the PHY connected to this controller.
+
+Recommended properties:
+- phy-connection-type : a string naming the controller/PHY interface type,
+ i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id" (Internal

+The Queue Manager is part of the Data-Path Acceleration Architecture (DPAA). QMan
+supports queuing and QoS scheduling of frames to CPUs, network interfaces and
+DPAA logic modules, maintains packet ordering within flows. Besides providing
+flow-level queuing, is also responsible for congestion management functions such
+as RED/WRED, congestion notifications and tail discards. This binding covers the
+CCSR space programming model

+
+QMan Private Memory Nodes
+
+QMan requires two contiguous range of physical memory used for the backing store
+for QMan Frame Queue Descriptor (FQD) and Packed Frame Descriptor Record (PFDR).
+This memory is reserved/allocated as a node under the /reserved-memory node.
+
+For additional details about reserved memory regions see reserved-memory.txt
+
+The QMan FQD memory node must be named "qman-fqd"
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: PPC platforms: Must include "fsl,qman-fqd"
+ ARM platforms: Must include "shared-dma-pool"
+ as well as the "no-map" property
+
+The QMan PFDR memory node must be named "qman-pfdr"
+
+PROPERTIES
+
+- compatible
+ Usage: required
+ Value type: <stringlist>
+ Definition: PPC platforms: Must include "fsl,qman-pfdr"
+ ARM platforms: Must include "shared-dma-pool"
+ as well as the "no-map" property
+
+The following constraints are relevant to the FQD and PFDR private memory:
+ - The size must be 2^(size + 1), with size = 11..29. That is 4 KiB to
+ 1 GiB
+ - The alignment must be a muliptle of the memory size
+
+The size of the FQD and PFDP must be chosen by observing the hardware features
+configured via the Reset Configuration Word (RCW) and that are relevant to a
+specific board (e.g. number of MAC(s) pinned-out, number of offline/host command
+FMan ports, etc.). The size configured in the DT must reflect the hardware
+capabilities and not the specific needs of an application
+
+For additional details about reserved memory regions see reserved-memory.txt
+
+EXAMPLE
+
+The example below shows a QMan FQD and a PFDR dynamic allocation memory nodes

+* Run Control and Power Management
+-------------------------------------------
+The RCPM performs all device-level tasks associated with device run control
+and power management.
+
+Required properites:
+ - reg : Offset and length of the register set of the RCPM block.
+ - #fsl,rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
+ fsl,rcpm-wakeup property.
+ - compatible : Must contain a chip-specific RCPM block compatible string
+ and (if applicable) may contain a chassis-version RCPM compatible
+ string. Chip-specific strings are of the form "fsl,<chip>-rcpm",
+ such as:
+ * "fsl,p2041-rcpm"
+ * "fsl,p5020-rcpm"
+ * "fsl,t4240-rcpm"
+
+ Chassis-version strings are of the form "fsl,qoriq-rcpm-<version>",
+ such as:
+ * "fsl,qoriq-rcpm-1.0": for chassis 1.0 rcpm
+ * "fsl,qoriq-rcpm-2.0": for chassis 2.0 rcpm
+ * "fsl,qoriq-rcpm-2.1": for chassis 2.1 rcpm
+ * "fsl,qoriq-rcpm-2.1+": for chassis 2.1+ rcpm
+
+All references to "1.0" and "2.0" refer to the QorIQ chassis version to
+which the chip complies.
+Chassis Version Example Chips
+--------------- -------------------------------
+1.0 p4080, p5020, p5040, p2041, p3041
+2.0 t4240, b4860, b4420
+2.1 t1040,
+2.1+ ls1021a, ls1012a, ls1043a, ls1046a
+
+Optional properties:
+ - little-endian : RCPM register block is Little Endian. Without it RCPM
+ will be Big Endian (default case).
+
+Example:
+The RCPM node for T4240:
+ rcpm: global-utilities@e2000 {
+ compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
+ reg = <0xe2000 0x1000>;
+ #fsl,rcpm-wakeup-cells = <2>;
+ };
+
+* Freescale RCPM Wakeup Source Device Tree Bindings
+-------------------------------------------
+Required fsl,rcpm-wakeup property should be added to a device node if the device
+can be used as a wakeup source.
+
+ - fsl,rcpm-wakeup: Consists of a phandle to the rcpm node and the IPPDEXPCR
+ register cells. The number of IPPDEXPCR register cells is defined in
+ "#fsl,rcpm-wakeup-cells" in the rcpm node. The first register cell is
+ the bit mask that should be set in IPPDEXPCR0, and the second register
+ cell is for IPPDEXPCR1, and so on.
+
+ Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
+ mechanism for keeping certain blocks awake during STANDBY and MEM, in
+ order to use them as wake-up sources.
+
+Example:
+ lpuart0: serial@2950000 {
+ compatible = "fsl,ls1021a-lpuart";
+ reg = <0x0 0x2950000 0x0 0x1000>;
+ interrupts = <GIC_SPI 80 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&sysclk>;
+ clock-names = "ipg";
+ fsl,rcpm-wakeup = <&rcpm 0x0 0x40000000>;
+ };

+The System Control Processor System (SCPSYS) has several power management
+related tasks in the system. The tasks include thermal measurement, dynamic
+voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
+The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
+domain control.
+
+The driver implements the Generic PM domain bindings described in
+power/power-domain.yaml. It provides the power domains defined in
+- include/dt-bindings/power/mt8173-power.h
+- include/dt-bindings/power/mt6797-power.h

+description: |
+ The Qualcomm RPM (Resource Power Manager) architecture includes a concept
+ of "RPM Masters". They can be thought of as "the local gang leaders", usually
+ spanning a single subsystem (e.g. APSS, ADSP, CDSP). All of the RPM decisions
+ (particularly around entering hardware-driven low power modes: XO shutdown
+ and total system-wide power collapse) are first made at Master-level, and
+ only then aggregated for the entire system.
+
+ The Master Stats provide a few useful bits that can be used to assess whether
+ our device has entered the desired low-power mode, how long it took to do so,
+ the duration of that residence, how long it took to come back online,
+ how many times a given sleep state was entered and which cores are actively
+ voting for staying awake.
+
+ This scheme has been used on various SoCs in the 2013-2023 era, with some
+ newer or higher-end designs providing this information through an SMEM query.

+
+description: |
+ Resource Power Manager Hardened (RPMH) is the mechanism for communicating
+ with the hardened resource accelerators on Qualcomm SoCs. Requests to the
+ resources can be written to the Trigger Command Set (TCS) registers and
+ using a (addr, val) pair and triggered. Messages in the TCS are then sent in
+ sequence over an internal bus.
+
+ The hardware block (Direct Resource Voter or DRV) is a part of the h/w entity
+ (Resource State Coordinator a.k.a RSC) that can handle multiple sleep and
+ active/wake resource requests. Multiple such DRVs can exist in a SoC and can
+ be written to from Linux. The structure of each DRV follows the same template
+ with a few variations that are captured by the properties here.
+
+ A TCS may be triggered from Linux or triggered by the F/W after all the CPUs
+ have powered off to facilitate idle power saving. TCS could be classified as::
+ ACTIVE - Triggered by Linux
+ SLEEP - Triggered by F/W
+ WAKE - Triggered by F/W
+ CONTROL - Triggered by F/W
+ See also:: <dt-bindings/soc/qcom,rpmh-rsc.h>
+
+ The order in which they are described in the DT, should match the hardware
+ configuration.
+
+ Requests can be made for the state of a resource, when the subsystem is
+ active or idle. When all subsystems like Modem, GPU, CPU are idle, the
+ resource state will be an aggregate of the sleep votes from each of those
+ subsystems. Clients may request a sleep value for their shared resources in
+ addition to the active mode requests.
+
+ Drivers that want to use the RSC to communicate with RPMH must specify their
+ bindings as child nodes of the RSC controllers they wish to communicate with.

+ The Ring Accelerator (RA) is a machine which converts read/write accesses

+ state of the ring (base address, current offset). The DMA controller
+ performs a read or write access to a specific address range (which maps to the
+ source interface on the RA) and the RA replaces the address for the transaction
+ with a new address which corresponds to the head or tail element of the ring
+ (head for reads, tail for writes).
+
+ The Ring Accelerator is a hardware module that is responsible for accelerating
+ management of the packet queues. The K3 SoCs can have more than one RA instances

+Keystone Navigator DMA Controller
+
+This document explains the device tree bindings for the packet dma
+on keystone devices. The Keystone Navigator DMA driver sets up the dma
+channels and flows for the QMSS(Queue Manager SubSystem) who triggers
+the actual data movements across clients using destination queues. Every
+client modules like NETCP(Network Coprocessor), SRIO(Serial Rapid IO),
+CRYPTO Engines etc has its own instance of dma hardware. QMSS has also
+an internal packet DMA module which is used as an infrastructure DMA
+with zero copy.
+
+Navigator DMA cloud layout:
+ ------------------
+ | Navigator DMAs |
+ ------------------
+ |
+ |-> DMA instance #0
+ |
+ |-> DMA instance #1
+ .
+ .
+ |
+ |-> DMA instance #n
+
+Navigator DMA properties:
+Required properties:
+ - compatible: Should be "ti,keystone-navigator-dma"
+ - clocks: phandle to dma instances clocks. The clock handles can be as
+ many as the dma instances. The order should be maintained as per
+ the dma instances.
+ - ti,navigator-cloud-address: Should contain base address for the multi-core
+ navigator cloud and number of addresses depends on SOC integration
+ configuration.. Navigator cloud global address needs to be programmed
+ into DMA and the DMA uses it as the physical addresses to reach queue
+ managers. Note that these addresses though points to queue managers,
+ they are relevant only from DMA perspective. The QMSS may not choose to
+ use them since it has a different address space view to reach all
+ its components.
+
+DMA instance properties:
+Required properties:
+ - reg: Should contain register location and length of the following dma
+ register regions. Register regions should be specified in the following
+ order.
+ - Global control register region (global).
+ - Tx DMA channel configuration register region (txchan).
+ - Rx DMA channel configuration register region (rxchan).
+ - Tx DMA channel Scheduler configuration register region (txsched).
+ - Rx DMA flow configuration register region (rxflow).
+
+Optional properties:
+ - reg-names: Names for the register regions.
+ - ti,enable-all: Enable all DMA channels vs clients opening specific channels
+ what they need. This property is useful for the userspace fast path
+ case where the linux drivers enables the channels used by userland
+ stack.
+ - ti,loop-back: To loopback Tx streaming I/F to Rx streaming I/F. Used for
+ infrastructure transfers.
+ - ti,rx-retry-timeout: Number of dma cycles to wait before retry on buffer
+ starvation.
+
+Example:
+
+ knav_dmas: knav_dmas@0 {
+ compatible = "ti,keystone-navigator-dma";
+ clocks = <&papllclk>, <&clkxge>;
+ #address-cells = <1>;

+ ranges;
+ ti,navigator-cloud-address = <0x23a80000 0x23a90000
+ 0x23aa0000 0x23ab0000>;
+

+ <0x2fa2000 0x400>;
+ reg-names = "global", "txchan", "rxchan",
+ "txsched", "rxflow";

+ };
+
+Navigator DMA client:
+Required properties:
+ - ti,navigator-dmas: List of one or more DMA specifiers, each consisting of
+ - A phandle pointing to DMA instance node
+ - A DMA channel number as a phandle arg.
+ - ti,navigator-dma-names: Contains dma channel name for each DMA specifier in
+ the 'ti,navigator-dmas' property.

+* Texas Instruments Keystone Navigator Queue Management SubSystem driver
+
+The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
+the main hardware sub system which forms the backbone of the Keystone
+multi-core Navigator. QMSS consist of queue managers, packed-data structure
+processors(PDSP), linking RAM, descriptor pools and infrastructure
+Packet DMA.
+The Queue Manager is a hardware module that is responsible for accelerating
+management of the packet queues. Packets are queued/de-queued by writing or
+reading descriptor address to a particular memory mapped location. The PDSPs
+perform QMSS related functions like accumulation, QoS, or event management.
+Linking RAM registers are used to link the descriptors which are stored in
+descriptor RAM. Descriptor RAM is configurable as internal or external memory.
+The QMSS driver manages the PDSP setups, linking RAM regions,
+queue pool management (allocation, push, pop and notify) and descriptor
+pool management.
+
+
+Required properties:
+- compatible : Must be "ti,keystone-navigator-qmss".
+ : Must be "ti,66ak2g-navss-qm" for QMSS on K2G SoC.
+- clocks : phandle to the reference clock for this device.
+- queue-range : <start number> total range of queue numbers for the device.
+- linkram0 : <address size> for internal link ram, where size is the total
+ link ram entries.
+- linkram1 : <address size> for external link ram, where size is the total
+ external link ram entries. If the address is specified as "0"
+ driver will allocate memory.
+- qmgrs : child node describing the individual queue managers on the
+ SoC. On keystone 1 devices there should be only one node.
+ On keystone 2 devices there can be more than 1 node.
+ -- managed-queues : the actual queues managed by each queue manager
+ instance, specified as <"base queue #" "# of queues">.
+ -- reg : Address and size of the register set for the device.
+ Register regions should be specified in the following
+ order
+ - Queue Peek region.
+ - Queue status RAM.
+ - Queue configuration region.
+ - Descriptor memory setup region.
+ - Queue Management/Queue Proxy region for queue Push.
+ - Queue Management/Queue Proxy region for queue Pop.
+
+For QMSS on K2G SoC, following QM reg indexes are used in that order
+ - Queue Peek region.
+ - Queue configuration region.
+ - Queue Management/Queue Proxy region for queue Push/Pop.
+
+- queue-pools : child node classifying the queue ranges into pools.
+ Queue ranges are grouped into 3 type of pools:
+ - qpend : pool of qpend(interruptible) queues
+ - general-purpose : pool of general queues, primarily used
+ as free descriptor queues or the
+ transmit DMA queues.
+ - accumulator : pool of queues on PDSP accumulator channel
+ Each range can have the following properties:
+ -- qrange : number of queues to use per queue range, specified as
+ <"base queue #" "# of queues">.
+ -- interrupts : Optional property to specify the interrupt mapping
+ for interruptible queues. The driver additionally sets
+ the interrupt affinity hint based on the cpu mask.
+ -- qalloc-by-id : Optional property to specify that the queues in this
+ range can only be allocated by queue id.
+ -- accumulator : Accumulator channel specification. Any of the PDSPs in
+ QMSS can be loaded with the accumulator firmware. The
+ accumulator firmware’s job is to poll a select number of
+ queues looking for descriptors that have been pushed
+ into them. Descriptors are popped from the queue and
+ placed in a buffer provided by the host. When the list
+ becomes full or a programmed time period expires, the
+ accumulator triggers an interrupt to the host to read
+ the buffer for descriptor information. This firmware
+ comes in 16, 32, and 48 channel builds. Each of these
+ channels can be configured to monitor 32 contiguous
+ queues. Accumulator channel property is specified as:
+ <pdsp-id, channel, entries, pacing mode, latency>
+ pdsp-id : QMSS PDSP running accumulator firmware
+ on which the channel has to be
+ configured
+ channel : Accumulator channel number
+ entries : Size of the accumulator descriptor list
+ pacing mode : Interrupt pacing mode
+ 0 : None, i.e interrupt on list full only
+ 1 : Time delay since last interrupt
+ 2 : Time delay since first new packet
+ 3 : Time delay since last new packet
+ latency : time to delay the interrupt, specified
+ in microseconds.
+ -- multi-queue : Optional property to specify that the channel has to
+ monitor up to 32 queues starting at the base queue #.
+- descriptor-regions : child node describing the memory regions for keystone
+ navigator packet DMA descriptors. The memory for
+ descriptors will be allocated by the driver.
+ -- id : region number in QMSS.
+ -- region-spec : specifies the number of descriptors in the
+ region, specified as
+ <"# of descriptors" "descriptor size">.
+ -- link-index : start index, i.e. index of the first
+ descriptor in the region.
+
+Optional properties:
+- dma-coherent : Present if DMA operations are coherent.
+- pdsps : child node describing the PDSP configuration.
+ -- firmware : firmware to be loaded on the PDSP.
+ -- id : the qmss pdsp that will run the firmware.
+ -- reg : Address and size of the register set for the PDSP.
+ Register regions should be specified in the following
+ order
+ - PDSP internal RAM region.
+ - PDSP control/status region registers.
+ - QMSS interrupt distributor registers.
+ - PDSP command interface region.

+ TI Programmable Real-Time Unit and Industrial Communication Subsystem

+
+description: |+
+
+ The Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
+ Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
+ cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
+ instruction RAMs, some internal peripheral modules to facilitate industrial
+ communication, and an interrupt controller.
+
+ The programmable nature of the PRUs provide flexibility to implement custom
+ peripheral interfaces, fast real-time responses, or specialized data handling.
+ The common peripheral modules include the following,
+ - an Ethernet MII_RT module with two MII ports
+ - an MDIO port to control external Ethernet PHYs
+ - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial
+ Ethernet functions
+ - an Enhanced Capture Module (eCAP)
+ - an Industrial Ethernet Timer with 7/9 capture and 16 compare events
+ - a 16550-compatible UART to support PROFIBUS
+ - Enhanced GPIO with async capture and serial support
+
+ A PRU-ICSS subsystem can have up to three shared data memories. A PRU core
+ acts on a primary Data RAM (there are usually 2 Data RAMs) at its address
+ 0x0, but also has access to a secondary Data RAM (primary to the other PRU
+ core) at its address 0x2000. A shared Data RAM, if present, can be accessed
+ by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
+ common to both the PRU cores. Each PRU core also has a private instruction
+ RAM, and specific register spaces for Control and Debug functionalities.
+
+ Various sub-modules within a PRU-ICSS subsystem are represented as individual
+ nodes and are defined using a parent-child hierarchy depending on their
+ integration within the IP and the SoC. These nodes are described in the
+ following sections.
+
+
+ PRU-ICSS Node
+ ==============
+ Each PRU-ICSS instance is represented as its own node with the individual PRU
+ processor cores, the memories node, an INTC node and an MDIO node represented
+ as child nodes within this PRUSS node. This node shall be a child of the
+ corresponding interconnect bus nodes or target-module nodes.
+
+ See ../../mfd/syscon.yaml for generic SysCon binding details.

+
+description: |+
+ The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+ (commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+ that cannot be controlled from the MPU, like suspend/resume and certain deep
+ C-states for CPU Idle. Once the wkup_m3_ipc driver uses the wkup_m3_rproc driver
+ to boot the wkup_m3, it handles communication with the CM3 using IPC registers
+ present in the SoC's control module and a mailbox. The wkup_m3_ipc exposes an
+ API to allow the SoC PM code to execute specific PM tasks.
+
+ Wkup M3 Device Node
+ ====================
+ A wkup_m3_ipc device node is used to represent the IPC registers within an
+ SoC.
+
+ Support for VTT Toggle with GPIO pin
+ ====================================
+ On some boards like the AM335x EVM-SK and the AM437x GP EVM, a GPIO pin is
+ connected to the enable pin on the DDR VTT regulator. This allows the
+ regulator to be disabled upon suspend and enabled upon resume. Please note
+ that the GPIO pin must be part of the GPIO0 module as only this GPIO module
+ is in the wakeup power domain.
+
+ Support for IO Isolation
+ ========================
+ On AM437x SoCs, certain pins can be forced into an alternate state when IO
+ isolation is activated. Those pins have pad control registers prefixed by
+ 'CTRL_CONF_' that contain DS0 (e.g. deep sleep) configuration bits that can
+ override the pin's existing bias (pull-up/pull-down) and value (high/low) when
+ IO isolation is active.
+
+ Support for I2C PMIC Voltage Scaling
+ ====================================
+ It is possible to pass the name of a binary file to load into the CM3 memory.
+ The binary data is the I2C sequences for the CM3 to send out to the PMIC
+ during low power mode entry.

+Device Tree bindings for the Armada 370 DB audio
+================================================
+
+These Device Tree bindings are used to describe the audio complex
+found on the Armada 370 DB platform.
+
+Mandatory properties:
+
+ * compatible: must be "marvell,a370db-audio"
+
+ * marvell,audio-controller: a phandle that points to the audio
+ controller of the Armada 370 SoC.
+
+ * marvell,audio-codec: a set of three phandles that points to:
+
+ 1/ the analog audio codec connected to the Armada 370 SoC
+ 2/ the S/PDIF transceiver
+ 3/ the S/PDIF receiver
+
+Example:
+
+ sound {
+ compatible = "marvell,a370db-audio";
+ marvell,audio-controller = <&audio_controller>;
+ marvell,audio-codec = <&audio_codec &spdif_out &spdif_in>;

+Devicetree bindings for the Axentia TSE-850 audio complex
+
+Required properties:
+ - compatible: "axentia,tse850-pcm5142"
+ - axentia,cpu-dai: The phandle of the cpu dai.
+ - axentia,audio-codec: The phandle of the PCM5142 codec.
+ - axentia,add-gpios: gpio specifier that controls the mixer.
+ - axentia,loop1-gpios: gpio specifier that controls loop relays on channel 1.
+ - axentia,loop2-gpios: gpio specifier that controls loop relays on channel 2.
+ - axentia,ana-supply: Regulator that supplies the output amplifier. Must
+ support voltages in the 2V - 20V range, in 1V steps.
+
+The schematics explaining the gpios are as follows:
+
+ loop1 relays
+ IN1 +---o +------------+ o---+ OUT1
+ \ /
+ + +
+ | / |
+ +--o +--. |
+ | add | |
+ | V |
+ | .---. |
+ DAC +----------->|Sum|---+
+ | '---' |
+ | |
+ + +
+
+ IN2 +---o--+------------+--o---+ OUT2
+ loop2 relays
+
+The 'loop1' gpio pin controls two relays, which are either in loop position,
+meaning that input and output are directly connected, or they are in mixer
+position, meaning that the signal is passed through the 'Sum' mixer. Similarly
+for 'loop2'.
+
+In the above, the 'loop1' relays are inactive, thus feeding IN1 to the mixer
+(if 'add' is active) and feeding the mixer output to OUT1. The 'loop2' relays
+are active, short-cutting the TSE-850 from channel 2. IN1, IN2, OUT1 and OUT2
+are TSE-850 connectors and DAC is the PCB name of the (filtered) output from
+the PCM5142 codec.
+
+Example:
+
+ &ssc0 {
+ #sound-dai-cells = <0>;
+
+ };

+ high performance analog to digital conversion, 4 channels of high
+ performance digital to analog conversion for audio, and 1 channel of

+
+ - reg : the I2C address of the device for I2C
+
+ - VA-supply, VP-supply : power supplies for the device,
+ as covered in
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Optional properties:
+
+ - reset-gpios : gpio used to reset the amplifier
+
+ - interrupts : IRQ line info CS35L33.
+ (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+ for further information relating to interrupt properties)
+
+ - cirrus,boost-ctl : Booster voltage use to supply the amp. If the value is
+ 0, then VBST = VP. If greater than 0, the boost voltage will be 3300mV with
+ a value of 1 and will increase at a step size of 100mV until a maximum of
+ 8000mV.
+
+ - cirrus,ramp-rate : On power up, it affects the time from when the power
+ up sequence begins to the time the audio reaches a full-scale output.
+ On power down, it affects the time from when the power-down sequence
+ begins to when the amplifier disables the PWM outputs. If this property
+ is not set then soft ramping will be disabled and ramp time would be
+ 20ms. If this property is set to 0,1,2,3 then ramp times would be 40ms,
+ 60ms,100ms,175ms respectively for 48KHz sample rate.
+
+ - cirrus,boost-ipk : The maximum current allowed for the boost converter.
+ The range starts at 1850000uA and goes to a maximum of 3600000uA
+ with a step size of 15625uA. The default is 2500000uA.
+
+ - cirrus,imon-adc-scale : Configures the scaling of data bits from the IMON
+ ADC data word. This property can be set as a value of 0 for bits 15 down
+ to 0, 6 for 21 down to 6, 7, for 22 down to 7, 8 for 23 down to 8.
+
+
+Optional H/G Algorithm sub-node:
+
+The cs35l33 node can have a single "cirrus,hg-algo" sub-node that will enable
+the internal H/G Algorithm.
+
+ - cirrus,hg-algo : Sub-node for internal Class H/G algorithm that
+ controls the amplifier supplies.
+
+Optional properties for the "cirrus,hg-algo" sub-node:
+
+ - cirrus,mem-depth : Memory depth for the Class H/G algorithm measured in
+ LRCLK cycles. If this property is set to 0, 1, 2, or 3 then the memory
+ depths will be 1, 4, 8, 16 LRCLK cycles. The default is 16 LRCLK cycles.
+
+ cirrus,release-rate : The number of consecutive LRCLK periods before
+ allowing release condition tracking updates. The number of LRCLK periods
+ start at 3 to a maximum of 255.
+
+ - cirrus,ldo-thld : Configures the signal threshold at which the PWM output
+ stage enters LDO operation. Starts as a default value of 50mV for a value
+ of 1 and increases with a step size of 50mV to a maximum of 750mV (value of
+ 0xF).
+
+ - cirrus,ldo-path-disable : This is a boolean property. If present, the H/G
+ algorithm uses the max detection path. If not present, the LDO
+ detection path is used.
+
+ - cirrus,ldo-entry-delay : The LDO entry delay in milliseconds before the H/G
+ algorithm switches to the LDO voltage. This property can be set to values
+ from 0 to 7 for delays of 5ms, 10ms, 50ms, 100ms, 200ms, 500ms, 1000ms.
+ The default is 100ms.
+
+ - cirrus,vp-hg-auto : This is a boolean property. When set, class H/G VPhg
+ automatic updating is enabled.
+
+ - cirrus,vp-hg : Class H/G algorithm VPhg. Controls the H/G algorithm's
+ reference to the VP voltage for when to start generating a boosted VBST.
+ The reference voltage starts at 3000mV with a value of 0x3 and is increased
+ by 100mV per step to a maximum of 5500mV.
+
+ - cirrus,vp-hg-rate : The rate (number of LRCLK periods) at which the VPhg is
+ allowed to increase to a higher voltage when using VPhg automatic
+ tracking. This property can be set to values from 0 to 3 with rates of 128
+ periods, 2048 periods, 32768 periods, and 524288 periods.
+ The default is 32768 periods.
+
+ - cirrus,vp-hg-va : VA calculation reference for automatic VPhg tracking
+ using VPMON. This property can be set to values from 0 to 6 starting at
+ 1800mV with a step size of 50mV up to a maximum value of 1750mV.

+Texas Instruments DaVinci McBSP module
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
+audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
+
+
+Required properties:
+~~~~~~~~~~~~~~~~~~~~
+- compatible :
+ "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
+
+- reg : physical base address and length of the controller memory mapped
+ region(s).
+- reg-names : Should contain:
+ * "mpu" for the main registers (required).
+ * "dat" for the data FIFO (optional).
+
+- dmas: three element list of DMA controller phandles, DMA request line and
+ TC channel ordered triplets.
+- dma-names: identifier string for each DMA request line in the dmas property.
+ These strings correspond 1:1 with the ordered pairs in dmas. The dma
+ identifiers must be "rx" and "tx".
+
+Optional properties:
+~~~~~~~~~~~~~~~~~~~~
+- interrupts : Interrupt numbers for McBSP
+- interrupt-names : Known interrupt names are "rx" and "tx"
+
+- pinctrl-0: Should specify pin control group used for this controller.
+- pinctrl-names: Should contain only one value - "default", for more details
+ please refer to pinctrl-bindings.txt
+
+Example (AM1808):
+~~~~~~~~~~~~~~~~~
+
+mcbsp0: mcbsp@1d10000 {
+ compatible = "ti,da850-mcbsp";
+ pinctrl-names = "default";
+ pinctrl-0 = <&mcbsp0_pins>;

+NXP Audio Mixer (AUDMIX).
+
+The Audio Mixer is a on-chip functional module that allows mixing of two
+audio streams into a single audio stream. Audio Mixer has two input serial
+audio interfaces. These are driven by two Synchronous Audio interface
+modules (SAI). Each input serial interface carries 8 audio channels in its
+frame in TDM manner. Mixer mixes audio samples of corresponding channels
+from two interfaces into a single sample. Before mixing, audio samples of
+two inputs can be attenuated based on configuration. The output of the
+Audio Mixer is also a serial audio interface. Like input interfaces it has
+the same TDM frame format. This output is used to drive the serial DAC TDM
+interface of audio codec and also sent to the external pins along with the
+receive path of normal audio SAI module for readback by the CPU.
+
+The output of Audio Mixer can be selected from any of the three streams
+ - serial audio input 1
+ - serial audio input 2
+ - mixed audio
+
+Mixing operation is independent of audio sample rate but the two audio
+input streams must have same audio sample rate with same number of channels
+in TDM frame to be eligible for mixing.
+
+Device driver required properties:
+=================================
+ - compatible : Compatible list, contains "fsl,imx8qm-audmix"
+
+ - reg : Offset and length of the register set for the device.
+
+ - clocks : Must contain an entry for each entry in clock-names.
+
+ - clock-names : Must include the "ipg" for register access.
+
+ - power-domains : Must contain the phandle to AUDMIX power domain node
+
+ - dais : Must contain a list of phandles to AUDMIX connected
+ DAIs. The current implementation requires two phandles
+ to SAI interfaces to be provided, the first SAI in the
+ list being used to route the AUDMIX output.
+

+Freescale Synchronous Serial Interface
+
+The SSI is a serial device that communicates with audio codecs. It can
+be programmed in AC97, I2S, left-justified, or right-justified modes.
+
+Required properties:
+- compatible: Compatible list, should contain one of the following
+ compatibles:
+ fsl,mpc8610-ssi
+ fsl,imx51-ssi
+ fsl,imx35-ssi
+ fsl,imx21-ssi
+- cell-index: The SSI, <0> = SSI1, <1> = SSI2, and so on.
+- reg: Offset and length of the register set for the device.
+- interrupts: <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and
+ level information for the interrupt. This should be
+ encoded based on the information in section 2)
+ depending on the type of interrupt controller you
+ have.
+- fsl,fifo-depth: The number of elements in the transmit and receive FIFOs.
+ This number is the maximum allowed value for SFCSR[TFWM0].
+ - clocks: "ipg" - Required clock for the SSI unit
+ "baud" - Required clock for SSI master mode. Otherwise this
+ clock is not used
+
+Required are also ac97 link bindings if ac97 is used. See
+Documentation/devicetree/bindings/sound/soc-ac97link.txt for the necessary
+bindings.
+
+Optional properties:
+- codec-handle: Phandle to a 'codec' node that defines an audio
+ codec connected to this SSI. This node is typically
+ a child of an I2C or other control node.
+- fsl,fiq-stream-filter: Bool property. Disabled DMA and use FIQ instead to
+ filter the codec stream. This is necessary for some boards
+ where an incompatible codec is connected to this SSI, e.g.
+ on pca100 and pcm043.
+- dmas: Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names: Two dmas have to be defined, "tx" and "rx", if fsl,imx-fiq
+ is not defined.
+- fsl,mode: The operating mode for the AC97 interface only.
+ "ac97-slave" - AC97 mode, SSI is clock slave
+ "ac97-master" - AC97 mode, SSI is clock master
+- fsl,ssi-asynchronous:
+ If specified, the SSI is to be programmed in asynchronous
+ mode. In this mode, pins SRCK, STCK, SRFS, and STFS must
+ all be connected to valid signals. In synchronous mode,
+ SRCK and SRFS are ignored. Asynchronous mode allows
+ playback and capture to use different sample sizes and
+ sample rates. Some drivers may require that SRCK and STCK
+ be connected together, and SRFS and STFS be connected
+ together. This would still allow different sample sizes,
+ but not different sample rates.
+- fsl,playback-dma: Phandle to a node for the DMA channel to use for
+ playback of audio. This is typically dictated by SOC
+ design. See the notes below.
+ Only used on Power Architecture.
+- fsl,capture-dma: Phandle to a node for the DMA channel to use for
+ capture (recording) of audio. This is typically dictated
+ by SOC design. See the notes below.
+ Only used on Power Architecture.
+
+Child 'codec' node required properties:
+- compatible: Compatible list, contains the name of the codec
+
+Child 'codec' node optional properties:
+- clock-frequency: The frequency of the input clock, which typically comes
+ from an on-board dedicated oscillator.
+
+Notes on fsl,playback-dma and fsl,capture-dma:
+
+On SOCs that have an SSI, specific DMA channels are hard-wired for playback
+and capture. On the MPC8610, for example, SSI1 must use DMA channel 0 for
+playback and DMA channel 1 for capture. SSI2 must use DMA channel 2 for
+playback and DMA channel 3 for capture. The developer can choose which
+DMA controller to use, but the channels themselves are hard-wired. The
+purpose of these two properties is to represent this hardware design.
+
+The device tree nodes for the DMA channels that are referenced by
+"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
+"fsl,ssi-dma-channel". The SOC-specific compatible string (e.g.
+"fsl,mpc8610-dma-channel") can remain. If these nodes are left as
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
+drivers (fsldma) will attempt to use them, and it will conflict with the
+sound drivers.

+Freescale Generic ASoC Sound Card with ASRC support
+
+The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
+SoCs connecting with external CODECs.
+
+The idea of this generic sound card is a bit like ASoC Simple Card. However,
+for Freescale SoCs (especially those released in recent years), most of them
+have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
+this is a specific feature that might be painstakingly controlled and merged
+into the Simple Card.
+
+So having this generic sound card allows all Freescale SoC users to benefit
+from the simplification of a new card support and the capability of the wide
+sample rates support through ASRC.
+
+Note: The card is initially designed for those sound cards who use AC'97, I2S
+ and PCM DAI formats. However, it'll be also possible to support those non
+ AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
+ long as the driver has been properly upgraded.
+
+
+The compatible list for this generic sound card currently:
+ "fsl,imx-audio-ac97"
+
+ "fsl,imx-audio-cs42888"
+
+ "fsl,imx-audio-cs427x"
+ (compatible with CS4271 and CS4272)
+
+ "fsl,imx-audio-wm8962"
+
+ "fsl,imx-audio-sgtl5000"
+ (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
+
+ "fsl,imx-audio-wm8960"
+
+ "fsl,imx-audio-mqs"
+
+ "fsl,imx-audio-wm8524"
+
+ "fsl,imx-audio-tlv320aic32x4"
+
+ "fsl,imx-audio-tlv320aic31xx"
+
+ "fsl,imx-audio-si476x"
+
+ "fsl,imx-audio-wm8958"
+
+ "fsl,imx-audio-nau8822"
+
+Required properties:
+
+ - compatible : Contains one of entries in the compatible list.
+
+ - model : The user-visible name of this sound complex
+
+ - audio-cpu : The phandle of an CPU DAI controller
+
+ - audio-codec : The phandle of an audio codec
+
+Optional properties:
+
+ - audio-asrc : The phandle of ASRC. It can be absent if there's no
+ need to add ASRC support via DPCM.
+
+ - audio-routing : A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the
+ connection's sink, the second being the connection's
+ source. There're a few pre-designed board connectors:
+ * Line Out Jack
+ * Line In Jack
+ * Headphone Jack
+ * Mic Jack
+ * Ext Spk
+ * AMIC (stands for Analog Microphone Jack)
+ * DMIC (stands for Digital Microphone Jack)
+
+ Note: The "Mic Jack" and "AMIC" are redundant while
+ coexisting in order to support the old bindings
+ of wm8962 and sgtl5000.
+
+ - hp-det-gpio : The GPIO that detect headphones are plugged in
+ - mic-det-gpio : The GPIO that detect microphones are plugged in
+ - bitclock-master : Indicates dai-link bit clock master; for details see simple-card.yaml.
+ - frame-master : Indicates dai-link frame master; for details see simple-card.yaml.
+ - dai-format : audio format, for details see simple-card.yaml.
+ - frame-inversion : dai-link uses frame clock inversion, for details see simple-card.yaml.
+ - bitclock-inversion : dai-link uses bit clock inversion, for details see simple-card.yaml.
+ - mclk-id : main clock id, specific for each card configuration.
+
+Optional unless SSI is selected as a CPU DAI:
+
+ - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
+
+ - mux-ext-port : The external port of the i.MX audio muxer
+
+Example:
+sound-cs42888 {
+ compatible = "fsl,imx-audio-cs42888";
+ model = "cs42888-audio";
+ audio-cpu = <&esai>;

+description: |
+ The Infineon PEB2466 codec is a programmable DSP-based four channels codec
+ with filters capabilities.
+
+ The time-slots used by the codec must be set and so, the properties
+ 'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and
+ 'dai-tdm-slot-rx-mask' must be present in the sound card node for sub-nodes
+ that involve the codec. The codec uses one 8bit time-slot per channel.
+ 'dai-tdm-tdm-slot-with' must be set to 8.
+
+ The PEB2466 codec also supports 28 gpios (signaling pins).

+ The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and

+ On later I2SMCC versions (starting with Microchip's SAMA7G5) I2S

+Required properties:

+- compatible:

+ "marvell,dove-audio" for Dove platforms
+ "marvell,armada370-audio" for Armada 370 platforms
+ "marvell,armada-380-audio" for Armada 38x platforms
+
+- reg: physical base address of the controller and length of memory mapped
+ region (named "i2s_regs").
+ With "marvell,armada-380-audio" two other regions are required:
+ first of those is dedicated for Audio PLL Configuration registers
+ (named "pll_regs") and the second one ("soc_ctrl") - for register
+ where one of exceptive I/O types (I2S or S/PDIF) is set.
+
+- interrupts:
+ with "marvell,kirkwood-audio", the audio interrupt
+ with "marvell,dove-audio", a list of two interrupts, the first for
+ the data flow, and the second for errors.
+
+- clocks: one or two phandles.
+ The first one is mandatory and defines the internal clock.
+ The second one is optional and defines an external clock.
+
+- clock-names: names associated to the clocks:
+ "internal" for the internal clock
+ "extclk" for the external clock
+
+Optional properties:
+
+- spdif-mode:
+ Enable S/PDIF mode on Armada 38x SoC. Using this property
+ disables standard I2S I/O. Valid only with "marvell,armada-380-audio"
+ compatible string.
+
+Example:
+
+i2s1: audio-controller@b4000 {

+description: |
+ Asynchronous Sample Rate Converter (ASRC) converts the sampling frequency
+ of the input signal from one frequency to another. It can handle over a
+ wide range of sample rate ratios (freq_in/freq_out) from 1:24 to 24:1.
+ ASRC has two modes of operation. One where ratio can be programmed in SW
+ and the other where it gets the information from ratio estimator module.
+
+ It supports sample rate conversions in the range of 8 to 192 kHz and
+ supports 6 streams upto 12 total channels. The input data size can be
+ 16, 24 and 32 bits.

+=============================================
+* SRC (Sampling Rate Converter)
+=============================================
+
+ [xx]Hz [yy]Hz
+ ------> [SRC] ------>
+
+SRC can convert [xx]Hz to [yy]Hz. Then, it has below 2 modes
+
+ Asynchronous mode: input data / output data are based on different clocks.
+ you can use this mode on Playback / Capture
+ Synchronous mode: input data / output data are based on same clocks.
+ This mode will be used if system doesn't have its input clock,
+ for example digital TV case.
+ you can use this mode on Playback
+
+------------------
+** Asynchronous mode
+------------------
+
+You need to use "simple-scu-audio-card" or "audio-graph-scu-card" for it.
+see "Example: simple sound card for Asynchronous mode"
+
+------------------
+** Synchronous mode
+------------------
+
+ > amixer set "SRC Out Rate" on
+ > aplay xxxx.wav
+ > amixer set "SRC Out Rate" 48000
+ > amixer set "SRC Out Rate" 44100
+
+=============================================
+* CTU (Channel Transfer Unit)
+=============================================
+
+ [xx]ch [yy]ch
+ ------> [CTU] -------->
+
+CTU can convert [xx]ch to [yy]ch, or exchange outputted channel.
+CTU conversion needs matrix settings.
+For more detail information, see below
+
+ Renesas R-Car datasheet
+ - Sampling Rate Converter Unit (SCU)
+ - SCU Operation
+ - CMD Block
+ - Functional Blocks in CMD

+ - Register Description
+ - CTUn Scale Value exx Register (CTUn_SVxxR)
+
+ ${LINUX}/sound/soc/sh/rcar/ctu.c
+ - comment of header
+
+You need to use "simple-scu-audio-card" or "audio-graph-scu-card" for it.
+see "Example: simple sound card for channel convert"
+
+Ex) Exchange output channel
+ Input -> Output
+ 1ch -> 0ch
+ 0ch -> 1ch
+
+ example of using matrix
+ output 0ch = (input 0ch x 0) + (input 1ch x 1)
+ output 1ch = (input 0ch x 1) + (input 1ch x 0)
+
+ amixer set "CTU Reset" on

+ amixer set "CTU SV1" 4194304,0
+
+ example of changing connection
+ amixer set "CTU Reset" on
+ amixer set "CTU Pass" 2,1
+
+=============================================
+* MIX (Mixer)
+=============================================
+
+MIX merges 2 sounds path. You can see 2 sound interface on system,
+and these sounds will be merged by MIX.
+
+ aplay -D plughw:0,0 xxxx.wav &
+ aplay -D plughw:0,1 yyyy.wav
+
+You need to use "simple-scu-audio-card" or "audio-graph-scu-card" for it.
+Ex)
+ [MEM] -> [SRC1] -> [CTU02] -+-> [MIX0] -> [DVC0] -> [SSI0]
+ |
+ [MEM] -> [SRC2] -> [CTU03] -+
+
+see "Example: simple sound card for MIXer"
+
+=============================================
+* DVC (Digital Volume and Mute Function)
+=============================================
+
+DVC controls Playback/Capture volume.
+
+Playback Volume
+ amixer set "DVC Out" 100%
+
+Capture Volume
+ amixer set "DVC In" 100%
+
+Playback Mute
+ amixer set "DVC Out Mute" on
+
+Capture Mute
+ amixer set "DVC In Mute" on
+
+Volume Ramp
+ amixer set "DVC Out Ramp Up Rate" "0.125 dB/64 steps"
+ amixer set "DVC Out Ramp Down Rate" "0.125 dB/512 steps"
+ amixer set "DVC Out Ramp" on
+ aplay xxx.wav &
+ amixer set "DVC Out" 80% // Volume Down
+ amixer set "DVC Out" 100% // Volume Up
+
+=============================================
+* SSIU (Serial Sound Interface Unit)
+=============================================
+
+SSIU can avoid some under/over run error, because it has some buffer.
+But you can't use it if SSI was PIO mode.
+In DMA mode, you can select not to use SSIU by using "no-busif" via SSI.
+
+SSIU handles BUSIF which will be used for TDM Split mode.
+This driver is assuming that audio-graph card will be used.
+
+TDM Split mode merges 4 sounds. You can see 4 sound interface on system,
+and these sounds will be merged SSIU/SSI.
+
+ aplay -D plughw:0,0 xxxx.wav &
+ aplay -D plughw:0,1 xxxx.wav &
+ aplay -D plughw:0,2 xxxx.wav &
+ aplay -D plughw:0,3 xxxx.wav
+
+ 2ch 8ch
+ [MEM] -> [SSIU 30] -+-> [SSIU 3] --> [Codec]
+ 2ch |
+ [MEM] -> [SSIU 31] -+
+ 2ch |
+ [MEM] -> [SSIU 32] -+
+ 2ch |
+ [MEM] -> [SSIU 33] -+
+
+see "Example: simple sound card for TDM Split"
+
+=============================================
+* SSI (Serial Sound Interface)
+=============================================
+
+** PIO mode
+
+You can use PIO mode which is for connection check by using.
+Note: The system will drop non-SSI modules in PIO mode
+even though if DT is selecting other modules.
+
+ &ssi0 {
+ pio-transfer
+ };
+
+** DMA mode without SSIU
+
+You can use DMA without SSIU.
+Note: under/over run, or noise are likely to occur
+
+ &ssi0 {
+ no-busif;
+ };
+
+** PIN sharing
+
+Each SSI can share WS pin. It is based on platform.
+This is example if SSI1 want to share WS pin with SSI0
+
+ &ssi1 {
+ shared-pin;
+ };
+
+** Multi-SSI
+
+You can use Multi-SSI.
+This is example of SSI0/SSI1/SSI2 (= for 6ch)
+
+see "Example: simple sound card for Multi channel"
+
+** TDM-SSI
+
+You can use TDM with SSI.
+This is example of TDM 6ch.
+Driver can automatically switches TDM <-> stereo mode in this case.
+
+see "Example: simple sound card for TDM"

+- "realtek,dc_offset_l_manual_mic"
+- "realtek,dc_offset_r_manual_mic"
+ Based on the different PCB layout, add the manual offset value to
+ compensate the DC offset for each L and R channel, and they are different
+ between headphone and headset.
+- "realtek,impedance_sensing_num"
+ The matrix row number of the impedance sensing table.
+ If the value is 0, it means the impedance sensing is not supported.
+- "realtek,impedance_sensing_table"
+ The matrix rows of the impedance sensing table are consisted by impedance
+ minimum, impedance maximum, volume, DC offset w/o and w/ mic of each L and
+ R channel accordingly. Example is shown as following.
+ < 0 300 7 0xffd160 0xffd1c0 0xff8a10 0xff8ab0
+ 301 65535 4 0xffe470 0xffe470 0xffb8e0 0xffb8e0>
+ The first and second column are defined for the impedance range. If the
+ detected impedance value is in the range, then the volume value of the
+ third column will be set to codec. In our codec design, each volume value
+ should compensate different DC offset to avoid the pop sound, and it is
+ also different between headphone and headset. In the example, the
+ "realtek,impedance_sensing_num" is 2. It means that there are 2 ranges of
+ impedance in the impedance sensing function.

+description:
+ Generic MIDI interface using a serial device. This denotes that a serial device is
+ dedicated to MIDI communication, either to an external MIDI device through a DIN5
+ or other connector, or to a known hardwired MIDI controller. This device must be a
+ child node of a serial node.
+
+ Can only be set to use standard baud rates corresponding to supported rates of the
+ parent serial device. If the standard MIDI baud of 31.25 kBaud is needed
+ (as would be the case if interfacing with arbitrary external MIDI devices),
+ configure the clocks of the parent serial device so that a requested baud of 38.4 kBaud
+ results in the standard MIDI baud rate, and set the 'current-speed' property to 38400 (default)

+The tas2552 serial control bus communicates through I2C protocols
+
+Required properties:
+ - compatible - One of:
+ "ti,tas2552" - TAS2552
+ - reg - I2C slave address: it can be 0x40 if ADDR pin is 0
+ or 0x41 if ADDR pin is 1.
+ - supply-*: Required supply regulators are:
+ "vbat" battery voltage
+ "iovdd" I/O Voltage
+ "avdd" Analog DAC Voltage
+
+Optional properties:
+ - enable-gpio - gpio pin to enable/disable the device
+
+tas2552 can receive its reference clock via MCLK, BCLK, IVCLKIN pin or use the
+internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM
+reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
+For system integration the dt-bindings/sound/tas2552.h header file provides
+defined values to select and configure the PLL and PDM reference clocks.
+
+Example:
+
+tas2552: tas2552@41 {
+ compatible = "ti,tas2552";
+ reg = <0x41>;
+ vbat-supply = <&reg_vbat>;
+ iovdd-supply = <&reg_iovdd>;
+ avdd-supply = <&reg_avdd>;
+ enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;

+For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit

+
+ - ti,charge-period: This property should contain the time in microseconds

+ waits for this period of time before starting the
+ PWM signals. This helps reduce pops and clicks.
+
+ When not specified, the hardware default of 1300ms
+ is retained.
+
+ - ti,mid-z-channel-X: Boolean properties, X being a number from 1 to 6.
+ If given, channel X will start with the Mid-Z start
+ sequence, otherwise the default Low-Z scheme is used.
+
+ The correct configuration depends on how the power

+description: |
+ Broadcom Broadband SoC supports High Speed SPI master controller since the
+ early MIPS based chips such as BCM6328 and BCM63268. This initial rev 1.0
+ controller was carried over to recent ARM based chips, such as BCM63138,
+ BCM4908 and BCM6858. The old MIPS based chip should continue to use the
+ brcm,bcm6328-hsspi compatible string. The recent ARM based chip is required to
+ use the brcm,bcmbca-hsspi-v1.0 as part of its compatible string list as
+ defined below to match the specific chip along with ip revision info.
+
+ This rev 1.0 controller has a limitation that can not keep the chip select line
+ active between the SPI transfers within the same SPI message. This can
+ terminate the transaction to some SPI devices prematurely. The issue can be
+ worked around by either the controller's prepend mode or using the dummy chip
+ select workaround. Driver automatically picks the suitable mode based on
+ transfer type so it is transparent to the user.
+
+ The newer SoCs such as BCM6756, BCM4912 and BCM6855 include an updated SPI
+ controller rev 1.1 that add the capability to allow the driver to control chip
+ select explicitly. This solves the issue in the old controller.

+

+* SPI (Serial Peripheral Interface)
+
+Required properties:
+- cell-index : QE SPI subblock index.
+ 0: QE subblock SPI1
+ 1: QE subblock SPI2
+- compatible : should be "fsl,spi" or "aeroflexgaisler,spictrl".
+- mode : the SPI operation mode, it can be "cpu" or "cpu-qe".
+- reg : Offset and length of the register set for the device
+- interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+- clock-frequency : input clock frequency to non FSL_SOC cores
+
+Optional properties:
+- cs-gpios : specifies the gpio pins to be used for chipselects.
+ The gpios will be referred to as reg = <index> in the SPI child nodes.
+ If unspecified, a single SPI device without a chip select can be used.
+- fsl,spisel_boot : for the MPC8306 and MPC8309, specifies that the
+ SPISEL_BOOT signal is used as chip select for a slave device. Use
+ reg = <number of gpios> in the corresponding child node, i.e. 0 if
+ the cs-gpios property is not present.
+
+Example:
+ spi@4c0 {
+ cell-index = <0>;
+ compatible = "fsl,spi";
+ reg = <4c0 40>;
+ interrupts = <82 0>;
+ interrupt-parent = <700>;
+ mode = "cpu";
+ cs-gpios = <&gpio 18 1 // device reg=<0>
+ &gpio 19 1>; // device reg=<1>
+ };
+
+
+* eSPI (Enhanced Serial Peripheral Interface)
+
+Required properties:
+- compatible : should be "fsl,mpc8536-espi".
+- reg : Offset and length of the register set for the device.
+- interrupts : should contain eSPI interrupt, the device has one interrupt.
+- fsl,espi-num-chipselects : the number of the chipselect signals.
+
+Optional properties:
+- fsl,csbef: chip select assertion time in bits before frame starts
+- fsl,csaft: chip select negation time in bits after frame ends
+
+Example:
+ spi@110000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,mpc8536-espi";
+ reg = <0x110000 0x1000>;
+ interrupts = <53 0x2>;
+ interrupt-parent = <&mpic>;
+ fsl,espi-num-chipselects = <4>;
+ fsl,csbef = <1>;
+ fsl,csaft = <1>;

+* ICP DAS LP-8841 SPI Controller for RTC
+
+ICP DAS LP-8841 contains a DS-1302 RTC. RTC is connected to an IO
+memory register, which acts as an SPI master device.
+
+The device uses the standard MicroWire half-duplex transfer timing.
+Master output is set on low clock and sensed by the RTC on the rising
+edge. Master input is set by the RTC on the trailing edge and is sensed
+by the master on low clock.
+
+Required properties:
+
+- #address-cells: should be 1
+
+- #size-cells: should be 0
+
+- compatible: should be "icpdas,lp8841-spi-rtc"
+
+- reg: should provide IO memory address
+
+Requirements to SPI slave nodes:
+
+- There can be only one slave device.
+
+- The spi slave node should claim the following flags which are
+ required by the spi controller.
+
+ - spi-3wire: The master itself has only 3 wire. It cannor work in
+ full duplex mode.
+
+ - spi-cs-high: DS-1302 has active high chip select line. The master
+ doesn't support active low.
+
+ - spi-lsb-first: DS-1302 requires least significant bit first
+ transfers. The master only support this type of bit ordering.
+
+
+Example:
+
+spi@901c {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "icpdas,lp8841-spi-rtc";
+ reg = <0x901c 0x1>;
+
+ rtc@0 {
+ compatible = "maxim,ds1302";
+ reg = <0>;
+ spi-max-frequency = <500000>;
+ spi-3wire;
+ spi-lsb-first;
+ spi-cs-high;
+ };
+};

+Required properties:
+- compatible: Should be "microchip,pic32mzda-spi".
+- reg: Address and length of register space for the device.
+- interrupts: Should contain all three spi interrupts in sequence
+ of <fault-irq>, <receive-irq>, <transmit-irq>.
+- interrupt-names: Should be "fault", "rx", "tx" in order.
+- clocks: Phandle of the clock generating SPI clock on the bus.
+- clock-names: Should be "mck0".
+- cs-gpios: Specifies the gpio pins to be used for chipselects.
+ See: Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Optional properties:

+description: |
+ SPI busses can be described with a node for the SPI controller device
+ and a set of child nodes for each SPI slave on the bus. The system SPI
+ controller may be described for use in SPI master mode or in SPI slave mode,
+ but not for both at the same time.

+
+ cs-gpios:
+ description: |
+ GPIOs used as chip selects.
+ If that property is used, the number of chip selects will be
+ increased automatically with max(cs-gpios, hardware chip selects).
+
+ So if, for example, the controller has 4 CS lines, and the
+ cs-gpios looks like this
+ cs-gpios = <&gpio1 0 0>, <0>, <&gpio1 1 0>, <&gpio1 2 0>;
+
+ Then it should be configured so that num_chipselect = 4, with
+ the following mapping
+ cs0 : &gpio1 0 0
+ cs1 : native
+ cs2 : &gpio1 1 0
+ cs3 : &gpio1 2 0
+
+ The second flag of a gpio descriptor can be GPIO_ACTIVE_HIGH (0)
+ or GPIO_ACTIVE_LOW(1). Legacy device trees often use 0.
+
+ There is a special rule set for combining the second flag of an
+ cs-gpio with the optional spi-cs-high flag for SPI slaves.
+
+ Each table entry defines how the CS pin is to be physically
+ driven (not considering potential gpio inversions by pinmux):
+
+ device node | cs-gpio | CS pin state active | Note
+ ================+===============+=====================+=====
+ spi-cs-high | - | H |
+ - | - | L |
+ spi-cs-high | ACTIVE_HIGH | H |
+ - | ACTIVE_HIGH | L | 1
+ spi-cs-high | ACTIVE_LOW | H | 2
+ - | ACTIVE_LOW | L |
+
+ Notes:
+ 1) Should print a warning about polarity inversion.
+ Here it would be wise to avoid and define the gpio as
+ ACTIVE_LOW.
+ 2) Should print a warning about polarity inversion
+ because ACTIVE_LOW is overridden by spi-cs-high.
+ Should be generally avoided and be replaced by
+ spi-cs-high + ACTIVE_HIGH.

+dm644x - https://www.ti.com/lit/ug/sprue32a/sprue32a.pdf
+OMAP-L138/da830 - http://www.ti.com/lit/ug/spruh77a/spruh77a.pdf
+
+Required properties:
+- #address-cells: number of cells required to define a chip select
+ address on the SPI bus. Should be set to 1.
+- #size-cells: should be zero.
+- compatible:
+ - "ti,dm6441-spi" for SPI used similar to that on DM644x SoC family
+ - "ti,da830-spi" for SPI used similar to that on DA8xx SoC family
+ - "ti,keystone-spi" for SPI used similar to that on Keystone2 SoC
+ family
+- reg: Offset and length of SPI controller register space
+- num-cs: Number of chip selects. This includes internal as well as
+ GPIO chip selects.
+- ti,davinci-spi-intr-line: interrupt line used to connect the SPI
+ IP to the interrupt controller within the SoC. Possible values
+ are 0 and 1. Manual says one of the two possible interrupt
+ lines can be tied to the interrupt controller. Set this
+ based on a specific SoC configuration.
+- interrupts: interrupt number mapped to CPU.
+- clocks: spi clk phandle
+ For 66AK2G this property should be set per binding,
+ Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
+
+SoC-specific Required Properties:
+
+The following are mandatory properties for Keystone 2 66AK2G SoCs only:
+
+- power-domains: Should contain a phandle to a PM domain provider node
+ and an args specifier containing the SPI device id
+ value. This property is as per the binding,
+
+Optional:
+- cs-gpios: gpio chip selects
+ For example to have 3 internal CS and 2 GPIO CS, user could define
+ cs-gpios = <0>, <0>, <0>, <&gpio1 30 0>, <&gpio1 31 0>;
+ where first three are internal CS and last two are GPIO CS.
+
+Optional properties for slave devices:
+SPI slave nodes can contain the following properties.
+Not all SPI Peripherals from Texas Instruments support this.
+Please check SPI peripheral documentation for a device before using these.
+
+- ti,spi-wdelay : delay between transmission of words
+ (SPIFMTn.WDELAY, SPIDAT1.WDEL) must be specified in number of SPI module
+ clock periods.
+
+ delay = WDELAY * SPI_module_clock_period + 2 * SPI_module_clock_period
+
+Below is timing diagram which shows functional meaning of
+"ti,spi-wdelay" parameter.

+Marvell Orion SPI device
+
+Required properties:
+- compatible : should be on of the following:
+ - "marvell,orion-spi" for the Orion, mv78x00, Kirkwood and Dove SoCs
+ - "marvell,armada-370-spi", for the Armada 370 SoCs
+ - "marvell,armada-375-spi", for the Armada 375 SoCs
+ - "marvell,armada-380-spi", for the Armada 38x SoCs
+ - "marvell,armada-390-spi", for the Armada 39x SoCs
+ - "marvell,armada-xp-spi", for the Armada XP SoCs
+- reg : offset and length of the register set for the device.
+ This property can optionally have additional entries to configure
+ the SPI direct access mode that some of the Marvell SoCs support
+ additionally to the normal indirect access (PIO) mode. The values
+ for the MBus "target" and "attribute" are defined in the Marvell
+ SoC "Functional Specifications" Manual in the chapter "Marvell
+ Core Processor Address Decoding".
+ The eight register sets following the control registers refer to
+ chip-select lines 0 through 7 respectively.
+- cell-index : Which of multiple SPI controllers is this.
+- clocks : pointers to the reference clocks for this device, the first
+ one is the one used for the clock on the spi bus, the
+ second one is optional and is the clock used for the
+ functional part of the controller
+
+Optional properties:
+- interrupts : Is currently not used.
+- clock-names : names of used clocks, mandatory if the second clock is
+ used, the name must be "core", and "axi" (the latter
+ is only for Armada 7K/8K).
+
+
+Example:
+ spi@10600 {
+ compatible = "marvell,orion-spi";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cell-index = <0>;
+ reg = <0x10600 0x28>;
+ interrupts = <23>;
+ };
+
+Example with SPI direct mode support (optionally):
+ spi0: spi@10600 {
+ compatible = "marvell,orion-spi";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cell-index = <0>;
+ reg = <MBUS_ID(0xf0, 0x01) 0x10600 0x28>, /* control */
+ <MBUS_ID(0x01, 0x1e) 0 0xffffffff>, /* CS0 */
+ <MBUS_ID(0x01, 0x5e) 0 0xffffffff>, /* CS1 */
+ <MBUS_ID(0x01, 0x9e) 0 0xffffffff>, /* CS2 */
+ <MBUS_ID(0x01, 0xde) 0 0xffffffff>, /* CS3 */
+ <MBUS_ID(0x01, 0x1f) 0 0xffffffff>, /* CS4 */
+ <MBUS_ID(0x01, 0x5f) 0 0xffffffff>, /* CS5 */
+ <MBUS_ID(0x01, 0x9f) 0 0xffffffff>, /* CS6 */
+ <MBUS_ID(0x01, 0xdf) 0 0xffffffff>; /* CS7 */
+ interrupts = <23>;
+ };
+
+To enable the direct mode, the board specific 'ranges' property in the
+'soc' node needs to add the entries for the desired SPI controllers
+and its chip-selects that are used in the direct mode instead of PIO
+mode. Here an example for this (SPI controller 0, device 1 and SPI
+controller 1, device 2 are used in direct mode. All other SPI device
+are used in the default indirect (PIO) mode):
+ soc {
+ /*
+ * Enable the SPI direct access by configuring an entry
+ * here in the board-specific ranges property
+ */
+ ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xf1000000 0x100000>, /* internal regs */
+ <MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000>, /* BootROM */
+ <MBUS_ID(0x01, 0x5e) 0 0 0xf1100000 0x10000>, /* SPI0-DEV1 */
+ <MBUS_ID(0x01, 0x9a) 0 0 0xf1110000 0x10000>; /* SPI1-DEV2 */
+

+
+description:
+ Many SPI controllers need to add properties to peripheral devices. They could
+ be common properties like spi-max-frequency, spi-cpha, etc. or they could be
+ controller specific like delay in clock or data lines, etc. These properties
+ need to be defined in the peripheral node because they are per-peripheral and
+ there can be multiple peripherals attached to a controller. All those
+ properties are listed here. The controller specific properties should go in
+ their own separate schema that should be referenced from here.

+description: |
+ ADI is the abbreviation of Anolog-Digital interface, which is used to access
+ analog chip (such as PMIC) from digital chip. ADI controller follows the SPI
+ framework for its hardware implementation is alike to SPI bus and its timing
+ is compatile to SPI timing.
+
+ ADI controller has 50 channels including 2 software read/write channels and
+ 48 hardware channels to access analog chip. For 2 software read/write channels,
+ users should set ADI registers to access analog chip. For hardware channels,
+ we can configure them to allow other hardware components to use it independently,
+ which means we can just link one analog chip address to one hardware channel,
+ then users can access the mapped analog chip address by this hardware channel
+ triggered by hardware components instead of ADI software channels.
+
+ Thus we introduce one property named "sprd,hw-channels" to configure hardware
+ channels, the first value specifies the hardware channel id which is used to
+ transfer data triggered by hardware automatically, and the second value specifies
+ the analog chip address where user want to access by hardware components.
+
+ Since we have multi-subsystems will use unique ADI to access analog chip, when
+ one system is reading/writing data by ADI software channels, that should be under
+ one hardware spinlock protection to prevent other systems from reading/writing
+ data by ADI software channels at the same time, or two parallel routine of setting
+ ADI registers will make ADI controller registers chaos to lead incorrect results.
+ Then we need one hardware spinlock to synchronize between the multiple subsystems.
+
+ The new version ADI controller supplies multiple master channels for different
+ subsystem accessing, that means no need to add hardware spinlock to synchronize,
+ thus change the hardware spinlock support to be optional to keep backward
+ compatibility.

+TI QSPI controller.
+
+Required properties:
+- compatible : should be "ti,dra7xxx-qspi" or "ti,am4372-qspi".
+- reg: Should contain QSPI registers location and length.
+- reg-names: Should contain the resource reg names.
+ - qspi_base: Qspi configuration register Address space
+ - qspi_mmap: Memory mapped Address space
+ - (optional) qspi_ctrlmod: Control module Address space
+- interrupts: should contain the qspi interrupt number.
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+- ti,hwmods: Name of the hwmod associated to the QSPI
+
+Recommended properties:
+- spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Optional properties:
+- syscon-chipselects: Handle to system control region contains QSPI
+ chipselect register and offset of that register.
+
+NOTE: TI QSPI controller requires different pinmux and IODelay
+parameters for Mode-0 and Mode-3 operations, which needs to be set up by
+the bootloader (U-Boot). Default configuration only supports Mode-0
+operation. Hence, "spi-cpol" and "spi-cpha" DT properties cannot be
+specified in the slave nodes of TI QSPI controller without appropriate
+modification to bootloader.

+==========================================
+Submitting Devicetree (DT) binding patches
+==========================================
+
+I. For patch submitters
+=======================
+
+ 0) Normal patch submission rules from
+ Documentation/process/submitting-patches.rst applies.
+
+ 1) The Documentation/ and include/dt-bindings/ portion of the patch should
+ be a separate patch. The preferred subject prefix for binding patches is::
+
+ "dt-bindings: <binding dir>: ..."
+
+ The 80 characters of the subject are precious. It is recommended to not
+ use "Documentation" or "doc" because that is implied. All bindings are
+ docs. Repeating "binding" again should also be avoided.
+
+ 2) DT binding files are written in DT schema format using json-schema
+ vocabulary and YAML file format. The DT binding files must pass validation
+ by running::
+
+ make dt_binding_check
+
+ See Documentation/devicetree/bindings/writing-schema.rst for more details
+ about schema and tools setup.
+
+ 3) DT binding files should be dual licensed. The preferred license tag is
+ (GPL-2.0-only OR BSD-2-Clause).
+
+ 4) Submit the entire series to the devicetree mailinglist at
+
+ devicetree@vger.kernel.org
+
+ and Cc: the DT maintainers. Use scripts/get_maintainer.pl to identify
+ all of the DT maintainers.
+
+ 5) The Documentation/ portion of the patch should come in the series before
+ the code implementing the binding.
+
+ 6) Any compatible strings used in a chip or board DTS file must be
+ previously documented in the corresponding DT binding text file
+ in Documentation/devicetree/bindings. This rule applies even if
+ the Linux device driver does not yet match on the compatible
+ string. [ checkpatch will emit warnings if this step is not
+ followed as of commit bff5da4335256513497cc8c79f9a9d1665e09864
+ ("checkpatch: add DT compatible string documentation checks"). ]
+
+ 7) The wildcard "<chip>" may be used in compatible strings, as in
+ the following example:
+
+ - compatible: Must contain '"nvidia,<chip>-pcie",
+ "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ...
+
+ As in the above example, the known values of "<chip>" should be
+ documented if it is used.
+
+ 8) If a documented compatible string is not yet matched by the
+ driver, the documentation should also include a compatible
+ string that is matched by the driver (as in the "nvidia,tegra20-pcie"
+ example above).
+
+ 9) Bindings are actively used by multiple projects other than the Linux
+ Kernel, extra care and consideration may need to be taken when making changes
+ to existing bindings.
+
+II. For kernel maintainers
+==========================
+
+ 1) If you aren't comfortable reviewing a given binding, reply to it and ask
+ the devicetree maintainers for guidance. This will help them prioritize
+ which ones to review and which ones are ok to let go.
+
+ 2) For driver (not subsystem) bindings: If you are comfortable with the
+ binding, and it hasn't received an Acked-by from the devicetree
+ maintainers after a few weeks, go ahead and take it.
+
+ For subsystem bindings (anything affecting more than a single device),
+ getting a devicetree maintainer to review it is required.
+
+ 3) For a series going though multiple trees, the binding patch should be
+ kept with the driver using the binding.
+
+III. Notes
+==========
+
+ 0) Please see Documentation/devicetree/bindings/ABI.rst for details
+ regarding devicetree ABI.
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.

+* Mediatek Thermal
+
+This describes the device tree binding for the Mediatek thermal controller
+which measures the on-SoC temperatures. This device does not have its own ADC,
+instead it directly controls the AUXADC via AHB bus accesses. For this reason
+this device needs phandles to the AUXADC. Also it controls a mux in the
+apmixedsys register space via AHB bus accesses, so a phandle to the APMIXEDSYS
+is also needed.
+
+Required properties:

+- mediatek,auxadc: A phandle to the AUXADC which the thermal controller uses
+- mediatek,apmixedsys: A phandle to the APMIXEDSYS controller.

+description: |
+ TSENSOR provides thermal and voltage sensors which monitor temperature
+ and voltage of the chip. Sensors are placed across the die to gauge the
+ temperature of the whole chip. The TSENSOR module:
+
+ Generates an interrupt to SW to lower temperature via DVFS on reaching
+ a certain thermal/voltage threshold.
+
+ Generates a signal to the CAR to reduce CPU frequency by half on reaching
+ a certain thermal/voltage threshold.
+
+ Generates a signal to the PMC when the temperature reaches dangerously high
+ levels to reset the chip and sets a flag in the PMC.
+
+ TSENSOR has two channels which monitor two different spots of the SoC.

+description: |
+ QCOM SoCs have TSENS IP to allow temperature measurement. There are currently
+ three distinct major versions of the IP that is supported by a single driver.
+ The IP versions are named v0.1, v1 and v2 in the driver, where v0.1 captures
+ everything before v1 when there was no versioning information.

+description: |
+ Thermal management is achieved in devicetree by describing the sensor hardware
+ and the software abstraction of cooling devices and thermal zones required to
+ take appropriate action to mitigate thermal overload.
+
+ The following node types are used to completely describe a thermal management
+ system in devicetree:
+ - thermal-sensor: device that measures temperature, has SoC-specific bindings
+ - cooling-device: device used to dissipate heat either passively or actively
+ - thermal-zones: a container of the following node types used to describe all
+ thermal data for the platform
+
+ This binding describes the cooling devices.
+
+ There are essentially two ways to provide control on power dissipation:
+ - Passive cooling: by means of regulating device performance. A typical
+ passive cooling mechanism is a CPU that has dynamic voltage and frequency
+ scaling (DVFS), and uses lower frequencies as cooling states.
+ - Active cooling: by means of activating devices in order to remove the
+ dissipated heat, e.g. regulating fan speeds.
+
+ Any cooling device has a range of cooling states (i.e. different levels of
+ heat dissipation). They also have a way to determine the state of cooling in
+ which the device is. For example, a fan's cooling states correspond to the
+ different fan speeds possible. Cooling states are referred to by single
+ unsigned integers, where larger numbers mean greater heat dissipation. The
+ precise set of cooling states associated with a device should be defined in
+ a particular device's binding.

+

+ active cooling is activated.
+
+ The maximum dT/dt is highly bound to hardware power consumption and
+ dissipation capability. The delays should be chosen to account for said
+ max dT/dt, such that a device does not cross several trip boundaries
+ unexpectedly between polls. Choosing the right polling delays shall avoid

+ and reduce silicon lifetime.

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+ - "ti,omap34xx-bandgap" : for OMAP34xx bandgap
+ - "ti,omap36xx-bandgap" : for OMAP36xx bandgap
+ - "ti,omap4430-bandgap" : for OMAP4430 bandgap
+ - "ti,omap4460-bandgap" : for OMAP4460 bandgap
+ - "ti,omap4470-bandgap" : for OMAP4470 bandgap
+ - "ti,omap5430-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- gpios : this entry should be used to inform which GPIO
+line the tshut signal is routed to. The informed GPIO will
+be treated as an IRQ;
+- regs : this entry must also be specified and it is specific
+to each bandgap version, because the mapping may change from
+soc to soc, apart of depending on available features.
+
+Example:
+OMAP34xx:
+bandgap {
+ reg = <0x48002524 0x4>;
+ compatible = "ti,omap34xx-bandgap";
+};
+
+OMAP36xx:
+bandgap {
+ reg = <0x48002524 0x4>;
+ compatible = "ti,omap36xx-bandgap";

+J-Core Programmable Interval Timer and Clocksource
+
+Required properties:
+
+- compatible: Must be "jcore,pit".
+
+- reg: Memory region(s) for timer/clocksource registers. For SMP,
+ there should be one region per cpu, indexed by the sequential,
+ zero-based hardware cpu number.
+
+- interrupts: An interrupt to assign for the timer. The actual pit
+ core is integrated with the aic and allows the timer interrupt
+ assignment to be programmed by software, but this property is
+ required in order to reserve an interrupt number that doesn't
+ conflict with other devices.
+
+
+Example:
+
+timer@200 {
+ compatible = "jcore,pit";
+ reg = < 0x200 0x30 0x500 0x30 >;
+ interrupts = < 0x48 >;

+maintainers:
+ - Biju Das <biju.das.jz@bp.renesas.com>
+
+description: |
+ This hardware block consists of eight 16-bit timer channels and one
+ 32- bit timer channel. It supports the following specifications:
+ - Pulse input/output: 28 lines max.
+ - Pulse input 3 lines
+ - Count clock 11 clocks for each channel (14 clocks for MTU0, 12 clocks
+ for MTU2, and 10 clocks for MTU5, four clocks for MTU1-MTU2 combination
+ (when LWA = 1))
+ - Operating frequency Up to 100 MHz
+ - Available operations [MTU0 to MTU4, MTU6, MTU7, and MTU8]
+ - Waveform output on compare match
+ - Input capture function (noise filter setting available)
+ - Counter-clearing operation
+ - Simultaneous writing to multiple timer counters (TCNT)
+ (excluding MTU8).
+ - Simultaneous clearing on compare match or input capture
+ (excluding MTU8).
+ - Simultaneous input and output to registers in synchronization with
+ counter operations (excluding MTU8).
+ - Up to 12-phase PWM output in combination with synchronous operation
+ (excluding MTU8)
+ - [MTU0 MTU3, MTU4, MTU6, MTU7, and MTU8]
+ - Buffer operation specifiable
+ - [MTU1, MTU2]
+ - Phase counting mode can be specified independently
+ - 32-bit phase counting mode can be specified for interlocked operation
+ of MTU1 and MTU2 (when TMDR3.LWA = 1)
+ - Cascade connection operation available
+ - [MTU3, MTU4, MTU6, and MTU7]
+ - Through interlocked operation of MTU3/4 and MTU6/7, the positive and
+ negative signals in six phases (12 phases in total) can be output in
+ complementary PWM and reset-synchronized PWM operation.
+ - In complementary PWM mode, values can be transferred from buffer
+ registers to temporary registers at crests and troughs of the timer-
+ counter values or when the buffer registers (TGRD registers in MTU4
+ and MTU7) are written to.
+ - Double-buffering selectable in complementary PWM mode.
+ - [MTU3 and MTU4]
+ - Through interlocking with MTU0, a mode for driving AC synchronous
+ motors (brushless DC motors) by using complementary PWM output and
+ reset-synchronized PWM output is settable and allows the selection
+ of two types of waveform output (chopping or level).
+ - [MTU5]
+ - Capable of operation as a dead-time compensation counter.
+ - [MTU0/MTU5, MTU1, MTU2, and MTU8]
+ - 32-bit phase counting mode specifiable by combining MTU1 and MTU2 and
+ through interlocked operation with MTU0/MTU5 and MTU8.
+ - Interrupt-skipping function
+ - In complementary PWM mode, interrupts on crests and troughs of counter
+ values and triggers to start conversion by the A/D converter can be
+ skipped.
+ - Interrupt sources: 43 sources.
+ - Buffer operation:
+ - Automatic transfer of register data (transfer from the buffer
+ register to the timer register).
+ - Trigger generation
+ - A/D converter start triggers can be generated
+ - A/D converter start request delaying function enables A/D converter
+ to be started with any desired timing and to be synchronized with
+ PWM output.
+ - Low power consumption function
+ - The MTU3a can be placed in the module-stop state.
+
+ There are two phase counting modes. 16-bit phase counting mode in which
+ MTU1 and MTU2 operate independently, and cascade connection 32-bit phase
+ counting mode in which MTU1 and MTU2 are cascaded.
+
+ In phase counting mode, the phase difference between two external input
+ clocks is detected and the corresponding TCNT is incremented or
+ decremented.
+ The below counters are supported
+ count0 - MTU1 16-bit phase counting
+ count1 - MTU2 16-bit phase counting
+ count2 - MTU1+ MTU2 32-bit phase counting
+
+ The module supports PWM mode{1,2}, Reset-synchronized PWM mode and
+ complementary PWM mode{1,2,3}.
+
+ In complementary PWM mode, six positive-phase and six negative-phase PWM
+ waveforms (12 phases in total) with dead time can be output by
+ combining MTU{3,4} and MTU{6,7}.
+
+ The below pwm channels are supported in pwm mode 1.
+ pwm0 - MTU0.MTIOC0A PWM mode 1
+ pwm1 - MTU0.MTIOC0C PWM mode 1
+ pwm2 - MTU1.MTIOC1A PWM mode 1
+ pwm3 - MTU2.MTIOC2A PWM mode 1
+ pwm4 - MTU3.MTIOC3A PWM mode 1
+ pwm5 - MTU3.MTIOC3C PWM mode 1
+ pwm6 - MTU4.MTIOC4A PWM mode 1
+ pwm7 - MTU4.MTIOC4C PWM mode 1
+ pwm8 - MTU6.MTIOC6A PWM mode 1
+ pwm9 - MTU6.MTIOC6C PWM mode 1
+ pwm10 - MTU7.MTIOC7A PWM mode 1
+ pwm11 - MTU7.MTIOC7C PWM mode 1

+description: |+
+ The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
+ global timer and CPU local timers. The global timer is a 64-bit free running
+ up-counter and can generate 4 interrupts when the counter reaches one of the
+ four preset counter values. The CPU local timers are 32-bit free running
+ down-counters and generate an interrupt when the counter expires. There is
+ one CPU local timer instantiated in MCT for every CPU in the system.

+description:
+ SiFive (and other RISC-V) SOCs include an implementation of the SiFive
+ Core Local Interruptor (CLINT) for M-mode timer and M-mode inter-processor
+ interrupts. It directly connects to the timer and inter-processor interrupt
+ lines of various HARTs (or CPUs) so RISC-V per-HART (or per-CPU) local
+ interrupt controller is the parent interrupt controller for CLINT device.
+ The clock frequency of CLINT is specified via "timebase-frequency" DT
+ property of "/cpus" DT node. The "timebase-frequency" DT property is
+ described in Documentation/devicetree/bindings/riscv/cpus.yaml
+
+ T-Head C906/C910 CPU cores include an implementation of CLINT too, however
+ their implementation lacks a memory-mapped MTIME register, thus not
+ compatible with SiFive ones.

+description: |
+ This is a list of trivial I2C and SPI devices that have simple device tree
+ bindings, consisting only of a compatible field, an address and possibly an
+ interrupt line.
+
+ If a device needs more specific bindings, such as properties to
+ describe some aspect of it, there needs to be a specific binding
+ document for it just like any other devices.

+at least a control module node, USB node and a PHY node. The second USB
+node and its PHY node are optional. The DMA node is also optional.
+
+Reset module
+~~~~~~~~~~~~
+- compatible: ti,am335x-usb-ctrl-module
+- reg: offset and length of the "USB control registers" in the "Control
+ Module" block. A second offset and length for the USB wake up control
+ in the same memory block.
+- reg-names: "phy_ctrl" for the "USB control registers" and "wakeup" for
+ the USB wake up control register.
+
+USB PHY
+~~~~~~~
+compatible: ti,am335x-usb-phy
+reg: offset and length of the "USB PHY" register space
+ti,ctrl_mod: reference to the "reset module" node
+reg-names: phy
+The PHY should have a "phy" alias numbered properly in the alias
+node.

+
+description: |
+ The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
+ in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
+ only.
+
+ A glue connects the DWC3 core to USB2 PHYs and optionally to an USB3 PHY.
+
+ One of the USB2 PHYs can be re-routed in peripheral mode to a DWC2 USB IP.
+
+ The DWC3 Glue controls the PHY routing and power, an interrupt line is
+ connected to the Glue to serve as OTG ID change detection.
+
+ The Amlogic A1 embeds a DWC3 USB IP Core configured for USB2 in
+ host-only mode.
+
+ The Amlogic GXL, GXM & AXG SoCs doesn't embed an USB3 PHY.

+ST DWC3 glue logic
+
+This file documents the parameters for the dwc3-st driver.
+This driver controls the glue logic used to configure the dwc3 core on
+STiH407 based platforms.
+
+Required properties:
+ - compatible : must be "st,stih407-dwc3"
+ - reg : glue logic base address and USB syscfg ctrl register offset
+ - reg-names : should be "reg-glue" and "syscfg-reg"
+ - st,syscon : should be phandle to system configuration node which
+ encompasses the glue registers
+ - resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the powerdown and softreset lines of the usb3 IP
+ - reset-names : list of reset signal names. Names should be "powerdown" and "softreset"
+See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+ with 'reg' property
+
+ - pinctl-names : A pinctrl state named "default" must be defined
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+ - pinctrl-0 : Pin control group
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+ - ranges : allows valid 1:1 translation between child's address space and
+ parent's address space
+
+Sub-nodes:
+The dwc3 core should be added as subnode to ST DWC3 glue as shown in the
+example below. The DT binding details of dwc3 can be found in:
+Documentation/devicetree/bindings/usb/snps,dwc3.yaml
+
+NB: The dr_mode property described in [1] is NOT optional for this driver, as the default value
+is "otg", which isn't supported by this SoC. Valid dr_mode values for dwc3-st are either "host"
+or "device".
+
+[1] Documentation/devicetree/bindings/usb/usb-drd.yaml
+
+Example:
+
+st_dwc3: dwc3@8f94000 {
+ compatible = "st,stih407-dwc3";
+ reg = <0x08f94000 0x1000>, <0x110 0x4>;

+Freescale SOC USB controllers
+
+The device node for a USB controller that is part of a Freescale
+SOC is as described in the document "Open Firmware Recommended
+Practice : Universal Serial Bus" with the following modifications
+and additions :
+
+Required properties :
+ - compatible : Should be "fsl-usb2-mph" for multi port host USB
+ controllers, or "fsl-usb2-dr" for dual role USB controllers
+ or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
+ Wherever applicable, the IP version of the USB controller should
+ also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
+ - phy_type : For multi port host USB controllers, should be one of
+ "ulpi", or "serial". For dual role USB controllers, should be
+ one of "ulpi", "utmi", "utmi_wide", or "serial".
+ - reg : Offset and length of the register set for the device
+ - port0 : boolean; if defined, indicates port0 is connected for
+ fsl-usb2-mph compatible controllers. Either this property or
+ "port1" (or both) must be defined for "fsl-usb2-mph" compatible
+ controllers.
+ - port1 : boolean; if defined, indicates port1 is connected for
+ fsl-usb2-mph compatible controllers. Either this property or
+ "port0" (or both) must be defined for "fsl-usb2-mph" compatible
+ controllers.
+ - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
+ controllers. Can be "host", "peripheral", or "otg". Default to
+ "host" if not defined for backward compatibility.
+
+Recommended properties :
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+
+Optional properties :
+ - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
+ port power polarity of internal PHY signal DRVVBUS is inverted.
+ - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
+ the PWR_FAULT signal polarity is inverted.
+
+Example multi port host USB controller device node :
+ usb@22000 {
+ compatible = "fsl-usb2-mph";
+ reg = <22000 1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = <700>;
+ interrupts = <27 1>;
+ phy_type = "ulpi";
+ port0;
+ port1;
+ };
+
+Example dual role USB controller device node :
+ usb@23000 {
+ compatible = "fsl-usb2-dr";
+ reg = <23000 1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = <700>;
+ interrupts = <26 1>;
+ dr_mode = "otg";
+ phy = "ulpi";
+ };
+
+Example dual role USB controller device node for MPC5121ADS:
+
+ usb@4000 {
+ compatible = "fsl,mpc5121-usb2-dr";
+ reg = <0x4000 0x1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = < &ipic >;
+ interrupts = <44 0x8>;
+ dr_mode = "otg";
+ phy_type = "utmi_wide";
+ fsl,invert-drvvbus;
+ fsl,invert-pwr-fault;
+ };

+USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.
+
+The GRUSBDC USB Device Controller core is available in the GRLIB VHDL
+IP core library.
+
+Note: In the ordinary environment for the core, a Leon SPARC system,
+these properties are built from information in the AMBA plug&play.
+
+Required properties:
+
+- name : Should be "GAISLER_USBDC" or "01_021"
+
+- reg : Address and length of the register set for the device
+
+- interrupts : Interrupt numbers for this device. Either one interrupt number
+ for all interrupts, or one for status related interrupts, one for IN
+ endpoint related interrupts and one for OUT endpoint related interrupts.
+
+Optional properties:
+
+- epobufsizes : Array of buffer sizes for OUT endpoints when they differ
+ from the default size of 1024. The array is indexed by the OUT endpoint
+ number. If the property is present it typically contains one entry for
+ each OUT endpoint of the core. Fewer entries overrides the default sizes
+ only for as many endpoints as the array contains.
+
+- epibufsizes : Array of buffer sizes for IN endpoints when they differ
+ from the default size of 1024. The array is indexed by the IN endpoint
+ number. If the property is present it typically contains one entry for
+ each IN endpoint of the core. Fewer entries overrides the default sizes
+ only for as many endpoints as the array contains.
+
+For further information look in the documentation for the GLIB IP core library:
+http://www.gaisler.com/products/grlib/grip.pdf

+title: Microchip USB5744 4-port Hub Controller
+
+description:
+ Microchip's USB5744 SmartHubTM IC is a 4 port, SuperSpeed (SS)/Hi-Speed (HS),
+ low power, low pin count configurable and fully compliant with the USB 3.1
+ Gen 1 specification. The USB5744 also supports Full Speed (FS) and Low Speed
+ (LS) USB signaling, offering complete coverage of all defined USB operating
+ speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0
+ controller, so 5 Gbps SuperSpeed data transfers are not affected by slower
+ USB 2.0 traffic.

+MSM SoC HSUSB controllers
+
+EHCI
+
+Required properties:
+- compatible: Should contain "qcom,ehci-host"
+- regs: offset and length of the register set in the memory map
+- usb-phy: phandle for the PHY device
+
+Example EHCI controller device node:
+
+ ehci: ehci@f9a55000 {
+ compatible = "qcom,ehci-host";
+ reg = <0xf9a55000 0x400>;
+ usb-phy = <&usb_otg>;
+ };
+
+USB PHY with optional OTG:
+
+Required properties:
+- compatible: Should contain:
+ "qcom,usb-otg-ci" for chipsets with ChipIdea 45nm PHY
+ "qcom,usb-otg-snps" for chipsets with Synopsys 28nm PHY
+
+- regs: Offset and length of the register set in the memory map
+- interrupts: interrupt-specifier for the OTG interrupt.
+
+- clocks: A list of phandle + clock-specifier pairs for the
+ clocks listed in clock-names
+- clock-names: Should contain the following:
+ "phy" USB PHY reference clock
+ "core" Protocol engine clock
+ "iface" Interface bus clock
+ "alt_core" Protocol engine clock for targets with asynchronous
+ reset methodology. (optional)
+
+- vdccx-supply: phandle to the regulator for the vdd supply for
+ digital circuit operation.
+- v1p8-supply: phandle to the regulator for the 1.8V supply
+- v3p3-supply: phandle to the regulator for the 3.3V supply
+
+- resets: A list of phandle + reset-specifier pairs for the
+ resets listed in reset-names
+- reset-names: Should contain the following:
+ "phy" USB PHY controller reset
+ "link" USB LINK controller reset
+
+- qcom,otg-control: OTG control (VBUS and ID notifications) can be one of
+ 1 - PHY control
+ 2 - PMIC control
+
+Optional properties:
+- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
+
+- switch-gpio: A phandle + gpio-specifier pair. Some boards are using Dual
+ SPDT USB Switch, witch is controlled by GPIO to de/multiplex
+ D+/D- USB lines between connectors.
+
+- qcom,phy-init-sequence: PHY configuration sequence values. This is related to Device
+ Mode Eye Diagram test. Start address at which these values will be
+ written is ULPI_EXT_VENDOR_SPECIFIC. Value of -1 is reserved as
+ "do not overwrite default value at this address".
+ For example: qcom,phy-init-sequence = < -1 0x63 >;
+ Will update only value at address ULPI_EXT_VENDOR_SPECIFIC + 1.
+
+- qcom,phy-num: Select number of pyco-phy to use, can be one of
+ 0 - PHY one, default
+ 1 - Second PHY
+ Some platforms may have configuration to allow USB
+ controller work with any of the two HSPHYs present.
+
+- qcom,vdd-levels: This property must be a list of three integer values
+ (no, min, max) where each value represents either a voltage
+ in microvolts or a value corresponding to voltage corner.
+
+- qcom,manual-pullup: If present, vbus is not routed to USB controller/phy
+ and controller driver therefore enables pull-up explicitly
+ before starting controller using usbcmd run/stop bit.
+
+- extcon: phandles to external connector devices. First phandle
+ should point to external connector, which provide "USB"
+ cable events, the second should point to external connector
+ device, which provide "USB-HOST" cable events. If one of
+ the external connector devices is not required empty <0>
+ phandle should be specified.
+
+Example HSUSB OTG controller device node:
+
+ usb@f9a55000 {
+ compatible = "qcom,usb-otg-snps";
+ reg = <0xf9a55000 0x400>;

+Tegra SOC USB controllers
+
+The device node for a USB controller that is part of a Tegra
+SOC is as described in the document "Open Firmware Recommended
+Practice : Universal Serial Bus" with the following modifications
+and additions :
+
+Required properties :
+ - compatible : For Tegra20, must contain "nvidia,tegra20-ehci".
+ For Tegra30, must contain "nvidia,tegra30-ehci". Otherwise, must contain
+ "nvidia,<chip>-ehci" plus at least one of the above, where <chip> is
+ tegra114, tegra124, tegra132, or tegra210.
+ - nvidia,phy : phandle of the PHY that the controller is connected to.
+ - clocks : Must contain one entry, for the module clock.
+ See ../clocks/clock-bindings.txt for details.
+ - resets : Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+ - reset-names : Must include the following entries:
+ - usb
+
+Optional properties:
+ - nvidia,needs-double-reset : boolean is to be set for some of the Tegra20
+ USB ports, which need reset twice due to hardware issues.

+ULPI bus binding
+----------------
+
+Phys that are behind a ULPI connection can be described with the following
+binding. The host controller shall have a "ulpi" named node as a child, and
+that node shall have one enabled node underneath it representing the ulpi
+device on the bus.

+EXAMPLE
+-------
+

+description: |
+ Usually, we only use device tree for hard wired USB device.
+ The reference binding doc is from:
+ http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
+
+ Four types of device-tree nodes are defined: "host-controller nodes"
+ representing USB host controllers, "device nodes" representing USB devices,
+ "interface nodes" representing USB interfaces and "combined nodes"
+ representing simple USB devices.
+
+ A combined node shall be used instead of a device node and an interface node
+ for devices of class 0 or 9 (hub) with a single configuration and a single
+ interface.
+
+ A "hub node" is a combined node or an interface node that represents a USB
+ hub.

+ The textual representation of VID and PID shall be in lower case
+ hexadecimal with leading zeroes suppressed. The other compatible

+ but a device adhering to this binding may leave out all except
+ for "usbVID,PID".

+title: virtio-iommu device using the virtio-pci transport
+
+maintainers:
+ - Jean-Philippe Brucker <jean-philippe@linaro.org>
+
+description: |
+ When virtio-iommu uses the PCI transport, its programming interface is
+ discovered dynamically by the PCI probing infrastructure. However the
+ device tree statically describes the relation between IOMMU and DMA
+ masters. Therefore, the PCI root complex that hosts the virtio-iommu
+ contains a child node representing the IOMMU device explicitly.
+
+ DMA from the IOMMU device isn't managed by another IOMMU. Therefore the
+ virtio-iommu node doesn't have an "iommus" property, and is omitted from
+ the iommu-map property of the root complex.
+
+properties:
+ # If compatible is present, it should contain the vendor and device ID
+ # according to the PCI Bus Binding specification. Since PCI provides
+ # built-in identification methods, compatible is not actually required.

+===================================================
+
+Onewire busses are described through nodes of their master bus controller.
+Slave devices are listed as sub-nodes of such master devices. For now, only
+one slave is allowed per bus master.
+
+
+Example:
+
+ charger: charger {

+Aspeed Watchdog Timer
+
+Required properties:
+ - compatible: must be one of:
+ - "aspeed,ast2400-wdt"
+ - "aspeed,ast2500-wdt"
+ - "aspeed,ast2600-wdt"
+
+ - reg: physical base address of the controller and length of memory mapped
+ region
+
+Optional properties:
+
+ - aspeed,reset-type = "cpu|soc|system|none"
+
+ Reset behavior - Whenever a timeout occurs the watchdog can be programmed
+ to generate one of three different, mutually exclusive, types of resets.
+
+ Type "none" can be specified to indicate that no resets are to be done.
+ This is useful in situations where another watchdog engine on chip is
+ to perform the reset.
+
+ If 'aspeed,reset-type=' is not specified the default is to enable system
+ reset.
+
+ Reset types:
+
+ - cpu: Reset CPU on watchdog timeout
+
+ - soc: Reset 'System on Chip' on watchdog timeout
+
+ - system: Reset system on watchdog timeout
+
+ - none: No reset is performed on timeout. Assumes another watchdog
+ engine is responsible for this.
+
+ - aspeed,alt-boot: If property is present then boot from alternate block.
+ - aspeed,external-signal: If property is present then signal is sent to
+ external reset counter (only WDT1 and WDT2). If not
+ specified no external signal is sent.
+ - aspeed,ext-pulse-duration: External signal pulse duration in microseconds
+
+Optional properties for AST2500-compatible watchdogs:
+ - aspeed,ext-push-pull: If aspeed,external-signal is present, set the pin's
+ drive type to push-pull. The default is open-drain.
+ - aspeed,ext-active-high: If aspeed,external-signal is present and and the pin
+ is configured as push-pull, then set the pulse
+ polarity to active-high. The default is active-low.
+
+Example:
+
+ wdt1: watchdog@1e785000 {
+ compatible = "aspeed,ast2400-wdt";
+ reg = <0x1e785000 0x1c>;
+ aspeed,reset-type = "system";

+Nuvoton NPCM Watchdog
+
+Nuvoton NPCM timer module provides five 24-bit timer counters, and a watchdog.
+The watchdog supports a pre-timeout interrupt that fires 10ms before the
+expiry.
+
+Required properties:
+- compatible : "nuvoton,npcm750-wdt" for NPCM750 (Poleg), or
+ "nuvoton,wpcm450-wdt" for WPCM450 (Hermon), or
+ "nuvoton,npcm845-wdt" for NPCM845 (Arbel).
+- reg : Offset and length of the register set for the device.
+- interrupts : Contain the timer interrupt with flags for
+ falling edge.
+
+Required clocking property, have to be one of:
+- clocks : phandle of timer reference clock.
+- clock-frequency : The frequency in Hz of the clock that drives the NPCM7xx
+ timer (usually 25000000).
+
+Optional properties:
+- timeout-sec : Contains the watchdog timeout in seconds
+
+Example:
+
+timer@f000801c {
+ compatible = "nuvoton,npcm750-wdt";
+ interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf000801c 0x4>;
+ clocks = <&clk NPCM7XX_CLK_TIMER>;

+ system some time to clean up, or notify others that it's going to reset.

+============================================================
+DOs and DON'Ts for designing and writing Devicetree bindings
+============================================================
+
+This is a list of common review feedback items focused on binding design. With
+every rule, there are exceptions and bindings have many gray areas.
+
+For guidelines related to patches, see
+Documentation/devicetree/bindings/submitting-patches.rst
+
+
+Overall design
+==============
+
+- DO attempt to make bindings complete even if a driver doesn't support some
+ features. For example, if a device has an interrupt, then include the
+ 'interrupts' property even if the driver is only polled mode.
+
+- DON'T refer to Linux or "device driver" in bindings. Bindings should be
+ based on what the hardware has, not what an OS and driver currently support.
+
+- DO use node names matching the class of the device. Many standard names are
+ defined in the DT Spec. If there isn't one, consider adding it.
+
+- DO check that the example matches the documentation especially after making
+ review changes.
+
+- DON'T create nodes just for the sake of instantiating drivers. Multi-function
+ devices only need child nodes when the child nodes have their own DT
+ resources. A single node can be multiple providers (e.g. clocks and resets).
+
+- DON'T use 'syscon' alone without a specific compatible string. A 'syscon'
+ hardware block should have a compatible string unique enough to infer the
+ register layout of the entire block (at a minimum).
+
+
+Properties
+==========
+
+- DO make 'compatible' properties specific. DON'T use wildcards in compatible
+ strings. DO use fallback compatibles when devices are the same as or a subset
+ of prior implementations. DO add new compatibles in case there are new
+ features or bugs.
+
+- DO use a vendor prefix on device-specific property names. Consider if
+ properties could be common among devices of the same class. Check other
+ existing bindings for similar devices.
+
+- DON'T redefine common properties. Just reference the definition and define
+ constraints specific to the device.
+
+- DO use common property unit suffixes for properties with scientific units.
+ Recommended suffixes are listed at
+ https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/property-units.yaml
+
+- DO define properties in terms of constraints. How many entries? What are
+ possible values? What is the order?
+
+Typical cases and caveats
+=========================
+
+- Phandle entries, like clocks/dmas/interrupts/resets, should always be
+ explicitly ordered. Include the {clock,dma,interrupt,reset}-names if there is
+ more than one phandle. When used, both of these fields need the same
+ constraints (e.g. list of items).
+
+- For names used in {clock,dma,interrupt,reset}-names, do not add any suffix,
+ e.g.: "tx" instead of "txirq" (for interrupt).
+
+- Properties without schema types (e.g. without standard suffix or not defined
+ by schema) need the type, even if this is an enum.
+
+- If schema includes other schema (e.g. /schemas/i2c/i2c-controller.yaml) use
+ "unevaluatedProperties:false". In other cases, usually use
+ "additionalProperties:false".
+
+- For sub-blocks/components of bigger device (e.g. SoC blocks) use rather
+ device-based compatible (e.g. SoC-based compatible), instead of custom
+ versioning of that component.
+ For example use "vendor,soc1234-i2c" instead of "vendor,i2c-v2".
+
+- "syscon" is not a generic property. Use vendor and type, e.g.
+ "vendor,power-manager-syscon".
+
+Board/SoC .dts Files
+====================
+
+- DO put all MMIO devices under a bus node and not at the top-level.
+
+- DO use non-empty 'ranges' to limit the size of child buses/devices. 64-bit
+ platforms don't need all devices to have 64-bit address and size.

+
+Writing Devicetree Bindings in json-schema
+==========================================
+
+Devicetree bindings are written using json-schema vocabulary. Schema files are
+written in a JSON-compatible subset of YAML. YAML is used instead of JSON as it
+is considered more human readable and has some advantages such as allowing
+comments (Prefixed with '#').
+
+Also see :ref:`example-schema`.
+
+Schema Contents
+---------------
+
+Each schema doc is a structured json-schema which is defined by a set of
+top-level properties. Generally, there is one binding defined per file. The
+top-level json-schema properties used are:
+
+$id
+ A json-schema unique identifier string. The string must be a valid
+ URI typically containing the binding's filename and path. For DT schema, it must
+ begin with "http://devicetree.org/schemas/". The URL is used in constructing
+ references to other files specified in schema "$ref" properties. A $ref value
+ with a leading '/' will have the hostname prepended. A $ref value with only a
+ relative path or filename will be prepended with the hostname and path
+ components of the current schema file's '$id' value. A URL is used even for
+ local files, but there may not actually be files present at those locations.
+
+$schema
+ Indicates the meta-schema the schema file adheres to.
+
+title
+ A one-line description on the contents of the binding schema.
+
+maintainers
+ A DT specific property. Contains a list of email address(es)
+ for maintainers of this binding.
+
+description
+ Optional. A multi-line text block containing any detailed
+ information about this binding. It should contain things such as what the block
+ or device does, standards the device conforms to, and links to datasheets for
+ more information.
+
+select
+ Optional. A json-schema used to match nodes for applying the
+ schema. By default, without 'select', nodes are matched against their possible
+ compatible-string values or node name. Most bindings should not need select.
+
+allOf
+ Optional. A list of other schemas to include. This is used to
+ include other schemas the binding conforms to. This may be schemas for a
+ particular class of devices such as I2C or SPI controllers.
+
+properties
+ A set of sub-schema defining all the DT properties for the
+ binding. The exact schema syntax depends on whether properties are known,
+ common properties (e.g. 'interrupts') or are binding/vendor-specific
+ properties.
+
+A property can also define a child DT node with child properties defined
+under it.
+
+For more details on properties sections, see 'Property Schema' section.
+
+patternProperties
+ Optional. Similar to 'properties', but names are regex.
+
+required
+ A list of DT properties from the 'properties' section that
+ must always be present.
+
+examples
+ Optional. A list of one or more DTS hunks implementing the
+ binding. Note: YAML doesn't allow leading tabs, so spaces must be used instead.
+
+Unless noted otherwise, all properties are required.
+
+Property Schema
+---------------
+
+The 'properties' section of the schema contains all the DT properties for a
+binding. Each property contains a set of constraints using json-schema
+vocabulary for that property. The properties schemas are what are used for
+validation of DT files.
+
+For common properties, only additional constraints not covered by the common,
+binding schema need to be defined such as how many values are valid or what
+possible values are valid.
+
+Vendor-specific properties will typically need more detailed schema. With the
+exception of boolean properties, they should have a reference to a type in
+schemas/types.yaml. A "description" property is always required.
+
+The Devicetree schemas don't exactly match the YAML-encoded DT data produced by
+dtc. They are simplified to make them more compact and avoid a bunch of
+boilerplate. The tools process the schema files to produce the final schema for
+validation. There are currently 2 transformations the tools perform.
+
+The default for arrays in json-schema is they are variable-sized and allow more
+entries than explicitly defined. This can be restricted by defining 'minItems',
+'maxItems', and 'additionalItems'. However, for DeviceTree Schemas, a fixed
+size is desired in most cases, so these properties are added based on the
+number of entries in an 'items' list.
+
+The YAML Devicetree format also makes all string values an array and scalar
+values a matrix (in order to define groupings) even when only a single value
+is present. Single entries in schemas are fixed up to match this encoding.
+
+Coding style
+------------
+
+Use YAML coding style (two-space indentation). For DTS examples in the schema,
+preferred is four-space indentation.
+
+Testing
+-------
+
+Dependencies
+~~~~~~~~~~~~
+
+The DT schema project must be installed in order to validate the DT schema
+binding documents and validate DTS files using the DT schema. The DT schema
+project can be installed with pip::
+
+ pip3 install dtschema
+
+Note that 'dtschema' installation requires 'swig' and Python development files
+installed first. On Debian/Ubuntu systems::
+
+ apt install swig python3-dev
+
+Several executables (dt-doc-validate, dt-mk-schema, dt-validate) will be
+installed. Ensure they are in your PATH (~/.local/bin by default).
+
+Recommended is also to install yamllint (used by dtschema when present).
+
+Running checks
+~~~~~~~~~~~~~~
+
+The DT schema binding documents must be validated using the meta-schema (the
+schema for the schema) to ensure they are both valid json-schema and valid
+binding schema. All of the DT binding documents can be validated using the
+``dt_binding_check`` target::
+
+ make dt_binding_check
+
+In order to perform validation of DT source files, use the ``dtbs_check`` target::
+
+ make dtbs_check
+
+Note that ``dtbs_check`` will skip any binding schema files with errors. It is
+necessary to use ``dt_binding_check`` to get all the validation errors in the
+binding schema files.
+
+It is possible to run both in a single command::
+
+ make dt_binding_check dtbs_check
+
+It is also possible to run checks with a subset of matching schema files by
+setting the ``DT_SCHEMA_FILES`` variable to a specific schema file or pattern.
+
+::
+
+ make dt_binding_check DT_SCHEMA_FILES=trivial-devices.yaml
+ make dt_binding_check DT_SCHEMA_FILES=/gpio/
+ make dtbs_check DT_SCHEMA_FILES=trivial-devices.yaml

+CE4100 Device Tree Bindings
+---------------------------
+
+The CE4100 SoC uses for in core peripherals the following compatible
+format: <vendor>,<chip>-<device>.
+Many of the "generic" devices like HPET or IO APIC have the ce4100
+name in their compatible property because they first appeared in this
+SoC.
+

+-------------
+

+ #size-cells = <0>;
+
+ cpu@0 {

+ };
+
+ cpu@2 {
+ device_type = "cpu";
+ compatible = "intel,ce4100";
+ reg = <0x02>;
+ };
+ };
+
+A "cpu" node describes one logical processor (hardware thread).
+
+Required properties:
+
+- device_type
+ Device type, must be "cpu".
+
+- reg
+ Local APIC ID, the unique number assigned to each processor by
+ system hardware.
+
+The SoC node
+------------
+
+This node describes the in-core peripherals. Required property:
+ compatible = "intel,ce4100-cp";
+
+The PCI node
+------------
+This node describes the PCI bus on the SoC. Its property should be
+ compatible = "intel,ce4100-pci", "pci";
+
+If the OS is using the IO-APIC for interrupt routing then the reported
+interrupt numbers for devices is no longer true. In order to obtain the
+correct interrupt number, the child node which represents the device has
+to contain the interrupt property. Besides the interrupt property it has
+to contain at least the reg property containing the PCI bus address and
+compatible property according to "PCI Bus Binding Revision 2.1".

+ d) Xilinx IP cores
+
+ The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+ in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
+ of standard device types (network, serial, etc.) and miscellaneous
+ devices (gpio, LCD, spi, etc). Also, since these devices are
+ implemented within the fpga fabric every instance of the device can be
+ synthesised with different options that change the behaviour.
+
+ Each IP-core has a set of parameters which the FPGA designer can use to
+ control how the core is synthesized. Historically, the EDK tool would
+ extract the device parameters relevant to device drivers and copy them
+ into an 'xparameters.h' in the form of #define symbols. This tells the
+ device drivers how the IP cores are configured, but it requires the kernel
+ to be recompiled every time the FPGA bitstream is resynthesized.
+
+ The new approach is to export the parameters into the device tree and
+ generate a new device tree each time the FPGA bitstream changes. The
+ parameters which used to be exported as #defines will now become
+ properties of the device node. In general, device nodes for IP-cores
+ will take the following form:
+
+ (name): (generic-name)@(base-address) {
+ compatible = "xlnx,(ip-core-name)-(HW_VER)"
+ [, (list of compatible devices), ...];
+ reg = <(baseaddr) (size)>;
+ interrupt-parent = <&interrupt-controller-phandle>;
+ interrupts = < ... >;
+ xlnx,(parameter1) = "(string-value)";
+ xlnx,(parameter2) = <(int-value)>;
+ };
+
+ (generic-name): an open firmware-style name that describes the
+ generic class of device. Preferably, this is one word, such
+ as 'serial' or 'ethernet'.
+ (ip-core-name): the name of the ip block (given after the BEGIN
+ directive in system.mhs). Should be in lowercase
+ and all underscores '_' converted to dashes '-'.
+ (name): is derived from the "PARAMETER INSTANCE" value.
+ (parameter#): C_* parameters from system.mhs. The C_ prefix is
+ dropped from the parameter name, the name is converted
+ to lowercase and all underscore '_' characters are
+ converted to dashes '-'.
+ (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
+ (HW_VER): from the HW_VER parameter.
+ (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
+
+ Typically, the compatible list will include the exact IP core version
+ followed by an older IP core version which implements the same
+ interface or any other device with the same interface.
+
+ 'reg' and 'interrupts' are all optional properties.
+
+ For example, the following block from system.mhs:
+
+ BEGIN opb_uartlite
+ PARAMETER INSTANCE = opb_uartlite_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BAUDRATE = 115200
+ PARAMETER C_DATA_BITS = 8
+ PARAMETER C_ODD_PARITY = 0
+ PARAMETER C_USE_PARITY = 0
+ PARAMETER C_CLK_FREQ = 50000000
+ PARAMETER C_BASEADDR = 0xEC100000
+ PARAMETER C_HIGHADDR = 0xEC10FFFF
+ BUS_INTERFACE SOPB = opb_7
+ PORT OPB_Clk = CLK_50MHz
+ PORT Interrupt = opb_uartlite_0_Interrupt
+ PORT RX = opb_uartlite_0_RX
+ PORT TX = opb_uartlite_0_TX
+ PORT OPB_Rst = sys_bus_reset_0
+ END
+
+ becomes the following device tree node:
+
+ opb_uartlite_0: serial@ec100000 {
+ device_type = "serial";
+ compatible = "xlnx,opb-uartlite-1.00.b";
+ reg = <ec100000 10000>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <1 0>; // got this from the opb_intc parameters
+ current-speed = <d#115200>; // standard serial device prop
+ clock-frequency = <d#50000000>; // standard serial device prop
+ xlnx,data-bits = <8>;
+ xlnx,odd-parity = <0>;
+ xlnx,use-parity = <0>;
+ };
+
+ That covers the general approach to binding xilinx IP cores into the
+ device tree. The following are bindings for specific devices:
+
+ i) Xilinx ML300 Framebuffer
+
+ Simple framebuffer device from the ML300 reference design (also on the
+ ML403 reference design as well as others).
+
+ Optional properties:
+ - resolution = <xres yres> : pixel resolution of framebuffer. Some
+ implementations use a different resolution.
+ Default is <d#640 d#480>
+ - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+ Default is <d#1024 d#480>.
+ - rotate-display (empty) : rotate display 180 degrees.
+
+ ii) Xilinx SystemACE
+
+ The Xilinx SystemACE device is used to program FPGAs from an FPGA
+ bitstream stored on a CF card. It can also be used as a generic CF
+ interface device.
+
+ Optional properties:
+ - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+ iii) Xilinx EMAC and Xilinx TEMAC
+
+ Xilinx Ethernet devices. In addition to general xilinx properties
+ listed above, nodes for these devices should include a phy-handle
+ property, and may include other common network device properties
+ like local-mac-address.
+
+ iv) Xilinx Uartlite
+
+ Xilinx uartlite devices are simple fixed speed serial ports.
+
+ Required properties:
+ - current-speed : Baud rate of uartlite
+
+ v) Xilinx hwicap
+
+ Xilinx hwicap devices provide access to the configuration logic
+ of the FPGA through the Internal Configuration Access Port
+ (ICAP). The ICAP enables partial reconfiguration of the FPGA,
+ readback of the configuration information, and some control over
+ 'warm boots' of the FPGA fabric.
+
+ Required properties:
+ - xlnx,family : The family of the FPGA, necessary since the
+ capabilities of the underlying ICAP hardware
+ differ between different families. May be
+ 'virtex2p', 'virtex4', or 'virtex5'.
+ - compatible : should contain "xlnx,xps-hwicap-1.00.a" or
+ "xlnx,opb-hwicap-1.00.b".
+
+ vi) Xilinx Uart 16550
+
+ Xilinx UART 16550 devices are very similar to the NS16550 but with
+ different register spacing and an offset from the base address.
+
+ Required properties:
+ - clock-frequency : Frequency of the clock input
+ - reg-offset : A value of 3 is required
+ - reg-shift : A value of 2 is required
+
+ vii) Xilinx USB Host controller
+
+ The Xilinx USB host controller is EHCI compatible but with a different
+ base address for the EHCI registers, and it is always a big-endian
+ USB Host controller. The hardware can be configured as high speed only,
+ or high speed/full speed hybrid.
+
+ Required properties:
+ - xlnx,support-usb-fs: A value 0 means the core is built as high speed
+ only. A value 1 means the core also supports
+ full speed devices.

+=====================
+Devicetree Changesets
+=====================
+
+A Devicetree changeset is a method which allows one to apply changes
+in the live tree in such a way that either the full set of changes
+will be applied, or none of them will be. If an error occurs partway
+through applying the changeset, then the tree will be rolled back to the
+previous state. A changeset can also be removed after it has been
+applied.
+
+When a changeset is applied, all of the changes get applied to the tree
+at once before emitting OF_RECONFIG notifiers. This is so that the
+receiver sees a complete and consistent state of the tree when it
+receives the notifier.
+
+The sequence of a changeset is as follows.
+
+1. of_changeset_init() - initializes a changeset
+
+2. A number of DT tree change calls, of_changeset_attach_node(),
+ of_changeset_detach_node(), of_changeset_add_property(),
+ of_changeset_remove_property, of_changeset_update_property() to prepare
+ a set of changes. No changes to the active tree are made at this point.
+ All the change operations are recorded in the of_changeset 'entries'
+ list.
+
+3. of_changeset_apply() - Apply the changes to the tree. Either the
+ entire changeset will get applied, or if there is an error the tree will
+ be restored to the previous state. The core ensures proper serialization
+ through locking. An unlocked version __of_changeset_apply is available,
+ if needed.
+
+If a successfully applied changeset needs to be removed, it can be done
+with of_changeset_revert().

+Devicetree Dynamic Resolver Notes
+=================================
+
+This document describes the implementation of the in-kernel
+DeviceTree resolver, residing in drivers/of/resolver.c
+
+How the resolver works
+----------------------
+
+The resolver is given as an input an arbitrary tree compiled with the
+proper dtc option and having a /plugin/ tag. This generates the
+appropriate __fixups__ & __local_fixups__ nodes.
+
+In sequence the resolver works by the following steps:
+
+1. Get the maximum device tree phandle value from the live tree + 1.
+2. Adjust all the local phandles of the tree to resolve by that amount.
+3. Using the __local__fixups__ node information adjust all local references
+ by the same amount.
+4. For each property in the __fixups__ node locate the node it references
+ in the live tree. This is the label used to tag the node.
+5. Retrieve the phandle of the target of the fixup.
+6. For each fixup in the property locate the node:property:offset location
+ and replace it with the phandle value.

+Open Firmware Devicetree Unittest
+=================================
+
+Author: Gaurav Minocha <gaurav.minocha.os@gmail.com>
+
+1. Introduction
+===============
+
+This document explains how the test data required for executing OF unittest
+is attached to the live tree dynamically, independent of the machine's
+architecture.
+
+It is recommended to read the following documents before moving ahead.
+
+(1) Documentation/devicetree/usage-model.rst
+(2) http://www.devicetree.org/Device_Tree_Usage
+
+OF Selftest has been designed to test the interface (include/linux/of.h)
+provided to device driver developers to fetch the device information..etc.
+from the unflattened device tree data structure. This interface is used by
+most of the device drivers in various use cases.
+
+
+2. Verbose Output (EXPECT)
+==========================
+
+If unittest detects a problem it will print a warning or error message to
+the console. Unittest also triggers warning and error messages from other
+kernel code as a result of intentionally bad unittest data. This has led
+to confusion as to whether the triggered messages are an expected result
+of a test or whether there is a real problem that is independent of unittest.
+
+'EXPECT \ : text' (begin) and 'EXPECT / : text' (end) messages have been
+added to unittest to report that a warning or error is expected. The
+begin is printed before triggering the warning or error, and the end is
+printed after triggering the warning or error.
+
+The EXPECT messages result in very noisy console messages that are difficult
+to read. The script scripts/dtc/of_unittest_expect was created to filter
+this verbosity and highlight mismatches between triggered warnings and
+errors vs expected warnings and errors. More information is available
+from 'scripts/dtc/of_unittest_expect --help'.
+
+
+3. Test-data
+============
+
+The Device Tree Source file (drivers/of/unittest-data/testcases.dts) contains
+the test data required for executing the unit tests automated in
+drivers/of/unittest.c. Currently, following Device Tree Source Include files
+(.dtsi) are included in testcases.dts::
+
+ drivers/of/unittest-data/tests-interrupts.dtsi
+ drivers/of/unittest-data/tests-platform.dtsi
+ drivers/of/unittest-data/tests-phandle.dtsi
+ drivers/of/unittest-data/tests-match.dtsi
+
+When the kernel is build with OF_SELFTEST enabled, then the following make
+rule::
+
+ $(obj)/%.dtb: $(src)/%.dts FORCE
+ $(call if_changed_dep, dtc)
+
+is used to compile the DT source file (testcases.dts) into a binary blob
+(testcases.dtb), also referred as flattened DT.
+
+After that, using the following rule the binary blob above is wrapped as an
+assembly file (testcases.dtb.S)::
+
+ $(obj)/%.dtb.S: $(obj)/%.dtb
+ $(call cmd, dt_S_dtb)
+
+The assembly file is compiled into an object file (testcases.dtb.o), and is
+linked into the kernel image.
+
+
+3.1. Adding the test data
+-------------------------
+
+Un-flattened device tree structure:
+
+Un-flattened device tree consists of connected device_node(s) in form of a tree
+structure described below::
+
+ // following struct members are used to construct the tree
+ struct device_node {
+ ...
+ struct device_node *parent;
+ struct device_node *child;
+ struct device_node *sibling;
+ ...
+ };
+
+Figure 1, describes a generic structure of machine's un-flattened device tree
+considering only child and sibling pointers. There exists another pointer,
+``*parent``, that is used to traverse the tree in the reverse direction. So, at
+a particular level the child node and all the sibling nodes will have a parent
+pointer pointing to a common node (e.g. child1, sibling2, sibling3, sibling4's
+parent points to root node)::
+
+ root ('/')
+ |
+ child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | |
+ | | | null
+ | | |
+ | | child31 -> sibling32 -> null
+ | | | |
+ | | null null
+ | |
+ | child21 -> sibling22 -> sibling23 -> null
+ | | | |
+ | null null null
+ |
+ child11 -> sibling12 -> sibling13 -> sibling14 -> null
+ | | | |
+ | | | null
+ | | |
+ null null child131 -> null
+ |
+ null
+
+Figure 1: Generic structure of un-flattened device tree
+
+
+Before executing OF unittest, it is required to attach the test data to
+machine's device tree (if present). So, when selftest_data_add() is called,
+at first it reads the flattened device tree data linked into the kernel image
+via the following kernel symbols::
+
+ __dtb_testcases_begin - address marking the start of test data blob
+ __dtb_testcases_end - address marking the end of test data blob
+
+Secondly, it calls of_fdt_unflatten_tree() to unflatten the flattened
+blob. And finally, if the machine's device tree (i.e live tree) is present,
+then it attaches the unflattened test data tree to the live tree, else it
+attaches itself as a live device tree.
+
+attach_node_and_children() uses of_attach_node() to attach the nodes into the
+live tree as explained below. To explain the same, the test data tree described
+in Figure 2 is attached to the live tree described in Figure 1::
+
+ root ('/')
+ |
+ testcase-data
+ |
+ test-child0 -> test-sibling1 -> test-sibling2 -> test-sibling3 -> null
+ | | | |
+ test-child01 null null null
+
+
+Figure 2: Example test data tree to be attached to live tree.
+
+According to the scenario above, the live tree is already present so it isn't
+required to attach the root('/') node. All other nodes are attached by calling
+of_attach_node() on each node.
+
+In the function of_attach_node(), the new node is attached as the child of the
+given parent in live tree. But, if parent already has a child then the new node
+replaces the current child and turns it into its sibling. So, when the testcase
+data node is attached to the live tree above (Figure 1), the final structure is
+as shown in Figure 3::
+
+ root ('/')
+ |
+ testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | | |
+ (...) | | | null
+ | | child31 -> sibling32 -> null
+ | | | |
+ | | null null
+ | |
+ | child21 -> sibling22 -> sibling23 -> null
+ | | | |
+ | null null null
+ |
+ child11 -> sibling12 -> sibling13 -> sibling14 -> null
+ | | | |
+ null null | null
+ |
+ child131 -> null
+ |
+ null
+ -----------------------------------------------------------------------
+
+ root ('/')
+ |
+ testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | | |
+ | (...) (...) (...) null
+ |
+ test-sibling3 -> test-sibling2 -> test-sibling1 -> test-child0 -> null
+ | | | |
+ null null null test-child01
+
+
+Figure 3: Live device tree structure after attaching the testcase-data.
+
+
+Astute readers would have noticed that test-child0 node becomes the last
+sibling compared to the earlier structure (Figure 2). After attaching first
+test-child0 the test-sibling1 is attached that pushes the child node
+(i.e. test-child0) to become a sibling and makes itself a child node,
+as mentioned above.
+
+If a duplicate node is found (i.e. if a node with same full_name property is
+already present in the live tree), then the node isn't attached rather its
+properties are updated to the live tree's node by calling the function
+update_node_properties().
+
+
+3.2. Removing the test data
+---------------------------
+
+Once the test case execution is complete, selftest_data_remove is called in
+order to remove the device nodes attached initially (first the leaf nodes are
+detached and then moving up the parent nodes are removed, and eventually the
+whole tree). selftest_data_remove() calls detach_node_and_children() that uses
+of_detach_node() to detach the nodes from the live device tree.
+
+To detach a node, of_detach_node() either updates the child pointer of given
+node's parent to its sibling or attaches the previous sibling to the given
+node's sibling, as appropriate. That is it :)

+========================
+Devicetree Overlay Notes
+========================
+
+This document describes the implementation of the in-kernel
+device tree overlay functionality residing in drivers/of/overlay.c and is a
+companion document to Documentation/devicetree/dynamic-resolution-notes.rst[1]
+
+How overlays work
+-----------------
+
+A Devicetree's overlay purpose is to modify the kernel's live tree, and
+have the modification affecting the state of the kernel in a way that
+is reflecting the changes.
+Since the kernel mainly deals with devices, any new device node that result
+in an active device should have it created while if the device node is either
+disabled or removed all together, the affected device should be deregistered.
+
+Lets take an example where we have a foo board with the following base tree::
+
+ ---- foo.dts ---------------------------------------------------------------
+ /* FOO platform */
+ /dts-v1/;
+ / {
+ compatible = "corp,foo";
+
+ /* shared resources */
+ res: res {
+ };
+
+ /* On chip peripherals */
+ ocp: ocp {
+ /* peripherals that are always instantiated */
+ peripheral1 { ... };
+ };
+ };
+ ---- foo.dts ---------------------------------------------------------------
+
+The overlay bar.dts,
+::
+
+ ---- bar.dts - overlay target location by label ----------------------------
+ /dts-v1/;
+ /plugin/;
+ &ocp {
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ };
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+when loaded (and resolved as described in [1]) should result in foo+bar.dts::
+
+ ---- foo+bar.dts -----------------------------------------------------------
+ /* FOO platform + bar peripheral */
+ / {
+ compatible = "corp,foo";
+
+ /* shared resources */
+ res: res {
+ };
+
+ /* On chip peripherals */
+ ocp: ocp {
+ /* peripherals that are always instantiated */
+ peripheral1 { ... };
+
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ };
+ };
+ };
+ ---- foo+bar.dts -----------------------------------------------------------
+
+As a result of the overlay, a new device node (bar) has been created
+so a bar platform device will be registered and if a matching device driver
+is loaded the device will be created as expected.
+
+If the base DT was not compiled with the -@ option then the "&ocp" label
+will not be available to resolve the overlay node(s) to the proper location
+in the base DT. In this case, the target path can be provided. The target
+location by label syntax is preferred because the overlay can be applied to
+any base DT containing the label, no matter where the label occurs in the DT.
+
+The above bar.dts example modified to use target path syntax is::
+
+ ---- bar.dts - overlay target location by explicit path --------------------
+ /dts-v1/;
+ /plugin/;
+ &{/ocp} {
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ }
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+
+Overlay in-kernel API
+--------------------------------
+
+The API is quite easy to use.
+
+1) Call of_overlay_fdt_apply() to create and apply an overlay changeset. The
+ return value is an error or a cookie identifying this overlay.
+
+2) Call of_overlay_remove() to remove and cleanup the overlay changeset
+ previously created via the call to of_overlay_fdt_apply(). Removal of an
+ overlay changeset that is stacked by another will not be permitted.
+
+Finally, if you need to remove all overlays in one-go, just call
+of_overlay_remove_all() which will remove every single one in the correct
+order.
+
+There is the option to register notifiers that get called on
+overlay operations. See of_overlay_notifier_register/unregister and
+enum of_overlay_notify_action for details.
+
+A notifier callback for OF_OVERLAY_PRE_APPLY, OF_OVERLAY_POST_APPLY, or
+OF_OVERLAY_PRE_REMOVE may store pointers to a device tree node in the overlay
+or its content but these pointers must not persist past the notifier callback
+for OF_OVERLAY_POST_REMOVE. The memory containing the overlay will be
+kfree()ed after OF_OVERLAY_POST_REMOVE notifiers are called. Note that the
+memory will be kfree()ed even if the notifier for OF_OVERLAY_POST_REMOVE
+returns an error.
+
+The changeset notifiers in drivers/of/dynamic.c are a second type of notifier
+that could be triggered by applying or removing an overlay. These notifiers
+are not allowed to store pointers to a device tree node in the overlay
+or its content. The overlay code does not protect against such pointers
+remaining active when the memory containing the overlay is freed as a result
+of removing the overlay.
+
+Any other code that retains a pointer to the overlay nodes or data is
+considered to be a bug because after removing the overlay the pointer
+will refer to freed memory.
+
+Users of overlays must be especially aware of the overall operations that
+occur on the system to ensure that other kernel code does not retain any
+pointers to the overlay nodes or data. Any example of an inadvertent use
+of such pointers is if a driver or subsystem module is loaded after an
+overlay has been applied, and the driver or subsystem scans the entire
+devicetree or a large portion of it, including the overlay nodes.

+
+The Linux usage model for device tree data
+
+:Author: Grant Likely <grant.likely@secretlab.ca>
+
+This article describes how Linux uses the device tree. An overview of
+the device tree data format can be found on the device tree usage page
+at devicetree.org\ [1]_.
+
+.. [1] https://www.devicetree.org/specifications/
+
+The "Open Firmware Device Tree", or simply Devicetree (DT), is a data
+structure and language for describing hardware. More specifically, it
+is a description of hardware that is readable by an operating system
+so that the operating system doesn't need to hard code details of the
+machine.
+
+Structurally, the DT is a tree, or acyclic graph with named nodes, and
+nodes may have an arbitrary number of named properties encapsulating
+arbitrary data. A mechanism also exists to create arbitrary
+links from one node to another outside of the natural tree structure.
+
+Conceptually, a common set of usage conventions, called 'bindings',
+is defined for how data should appear in the tree to describe typical
+hardware characteristics including data busses, interrupt lines, GPIO
+connections, and peripheral devices.
+
+As much as possible, hardware is described using existing bindings to
+maximize use of existing support code, but since property and node
+names are simply text strings, it is easy to extend existing bindings
+or create new ones by defining new nodes and properties. Be wary,
+however, of creating a new binding without first doing some homework
+about what already exists. There are currently two different,
+incompatible, bindings for i2c busses that came about because the new
+binding was created without first investigating how i2c devices were
+already being enumerated in existing systems.
+
+1. History
+----------
+The DT was originally created by Open Firmware as part of the
+communication method for passing data from Open Firmware to a client
+program (like to an operating system). An operating system used the
+Device Tree to discover the topology of the hardware at runtime, and
+thereby support a majority of available hardware without hard coded
+information (assuming drivers were available for all devices).
+
+Since Open Firmware is commonly used on PowerPC and SPARC platforms,
+the Linux support for those architectures has for a long time used the
+Device Tree.
+
+In 2005, when PowerPC Linux began a major cleanup and to merge 32-bit
+and 64-bit support, the decision was made to require DT support on all
+powerpc platforms, regardless of whether or not they used Open
+Firmware. To do this, a DT representation called the Flattened Device
+Tree (FDT) was created which could be passed to the kernel as a binary
+blob without requiring a real Open Firmware implementation. U-Boot,
+kexec, and other bootloaders were modified to support both passing a
+Device Tree Binary (dtb) and to modify a dtb at boot time. DT was
+also added to the PowerPC boot wrapper (``arch/powerpc/boot/*``) so that
+a dtb could be wrapped up with the kernel image to support booting
+existing non-DT aware firmware.
+
+Some time later, FDT infrastructure was generalized to be usable by
+all architectures. At the time of this writing, 6 mainlined
+architectures (arm, microblaze, mips, powerpc, sparc, and x86) and 1
+out of mainline (nios) have some level of DT support.
+
+2. Data Model
+-------------
+If you haven't already read the Device Tree Usage\ [1]_ page,
+then go read it now. It's okay, I'll wait....
+
+2.1 High Level View
+-------------------
+The most important thing to understand is that the DT is simply a data
+structure that describes the hardware. There is nothing magical about
+it, and it doesn't magically make all hardware configuration problems
+go away. What it does do is provide a language for decoupling the
+hardware configuration from the board and device driver support in the
+Linux kernel (or any other operating system for that matter). Using
+it allows board and device support to become data driven; to make
+setup decisions based on data passed into the kernel instead of on
+per-machine hard coded selections.
+
+Ideally, data driven platform setup should result in less code
+duplication and make it easier to support a wide range of hardware
+with a single kernel image.
+
+Linux uses DT data for three major purposes:
+
+1) platform identification,
+2) runtime configuration, and
+3) device population.
+
+2.2 Platform Identification
+---------------------------
+First and foremost, the kernel will use data in the DT to identify the
+specific machine. In a perfect world, the specific platform shouldn't
+matter to the kernel because all platform details would be described
+perfectly by the device tree in a consistent and reliable manner.
+Hardware is not perfect though, and so the kernel must identify the
+machine during early boot so that it has the opportunity to run
+machine-specific fixups.
+
+In the majority of cases, the machine identity is irrelevant, and the
+kernel will instead select setup code based on the machine's core
+CPU or SoC. On ARM for example, setup_arch() in
+arch/arm/kernel/setup.c will call setup_machine_fdt() in
+arch/arm/kernel/devtree.c which searches through the machine_desc
+table and selects the machine_desc which best matches the device tree
+data. It determines the best match by looking at the 'compatible'
+property in the root device tree node, and comparing it with the
+dt_compat list in struct machine_desc (which is defined in
+arch/arm/include/asm/mach/arch.h if you're curious).
+
+The 'compatible' property contains a sorted list of strings starting
+with the exact name of the machine, followed by an optional list of
+boards it is compatible with sorted from most compatible to least. For
+example, the root compatible properties for the TI BeagleBoard and its
+successor, the BeagleBoard xM board might look like, respectively::
+
+ compatible = "ti,omap3-beagleboard", "ti,omap3450", "ti,omap3";
+ compatible = "ti,omap3-beagleboard-xm", "ti,omap3450", "ti,omap3";
+
+Where "ti,omap3-beagleboard-xm" specifies the exact model, it also
+claims that it compatible with the OMAP 3450 SoC, and the omap3 family
+of SoCs in general. You'll notice that the list is sorted from most
+specific (exact board) to least specific (SoC family).
+
+Astute readers might point out that the Beagle xM could also claim
+compatibility with the original Beagle board. However, one should be
+cautioned about doing so at the board level since there is typically a
+high level of change from one board to another, even within the same
+product line, and it is hard to nail down exactly what is meant when one
+board claims to be compatible with another. For the top level, it is
+better to err on the side of caution and not claim one board is
+compatible with another. The notable exception would be when one
+board is a carrier for another, such as a CPU module attached to a
+carrier board.
+
+One more note on compatible values. Any string used in a compatible
+property must be documented as to what it indicates. Add
+documentation for compatible strings in Documentation/devicetree/bindings.
+
+Again on ARM, for each machine_desc, the kernel looks to see if
+any of the dt_compat list entries appear in the compatible property.
+If one does, then that machine_desc is a candidate for driving the
+machine. After searching the entire table of machine_descs,
+setup_machine_fdt() returns the 'most compatible' machine_desc based
+on which entry in the compatible property each machine_desc matches
+against. If no matching machine_desc is found, then it returns NULL.
+
+The reasoning behind this scheme is the observation that in the majority
+of cases, a single machine_desc can support a large number of boards
+if they all use the same SoC, or same family of SoCs. However,
+invariably there will be some exceptions where a specific board will
+require special setup code that is not useful in the generic case.
+Special cases could be handled by explicitly checking for the
+troublesome board(s) in generic setup code, but doing so very quickly
+becomes ugly and/or unmaintainable if it is more than just a couple of
+cases.
+
+Instead, the compatible list allows a generic machine_desc to provide
+support for a wide common set of boards by specifying "less
+compatible" values in the dt_compat list. In the example above,
+generic board support can claim compatibility with "ti,omap3" or
+"ti,omap3450". If a bug was discovered on the original beagleboard
+that required special workaround code during early boot, then a new
+machine_desc could be added which implements the workarounds and only
+matches on "ti,omap3-beagleboard".
+
+PowerPC uses a slightly different scheme where it calls the .probe()
+hook from each machine_desc, and the first one returning TRUE is used.
+However, this approach does not take into account the priority of the
+compatible list, and probably should be avoided for new architecture
+support.
+
+2.3 Runtime configuration
+-------------------------
+In most cases, a DT will be the sole method of communicating data from
+firmware to the kernel, so also gets used to pass in runtime and
+configuration data like the kernel parameters string and the location
+of an initrd image.
+
+Most of this data is contained in the /chosen node, and when booting
+Linux it will look something like this::
+
+ chosen {
+ bootargs = "console=ttyS0,115200 loglevel=8";
+ initrd-start = <0xc8000000>;
+ initrd-end = <0xc8200000>;
+ };
+
+The bootargs property contains the kernel arguments, and the initrd-*
+properties define the address and size of an initrd blob. Note that
+initrd-end is the first address after the initrd image, so this doesn't
+match the usual semantic of struct resource. The chosen node may also
+optionally contain an arbitrary number of additional properties for
+platform-specific configuration data.
+
+During early boot, the architecture setup code calls of_scan_flat_dt()
+several times with different helper callbacks to parse device tree
+data before paging is setup. The of_scan_flat_dt() code scans through
+the device tree and uses the helpers to extract information required
+during early boot. Typically the early_init_dt_scan_chosen() helper
+is used to parse the chosen node including kernel parameters,
+early_init_dt_scan_root() to initialize the DT address space model,
+and early_init_dt_scan_memory() to determine the size and
+location of usable RAM.
+
+On ARM, the function setup_machine_fdt() is responsible for early
+scanning of the device tree after selecting the correct machine_desc
+that supports the board.
+
+2.4 Device population
+---------------------
+After the board has been identified, and after the early configuration data
+has been parsed, then kernel initialization can proceed in the normal
+way. At some point in this process, unflatten_device_tree() is called
+to convert the data into a more efficient runtime representation.
+This is also when machine-specific setup hooks will get called, like
+the machine_desc .init_early(), .init_irq() and .init_machine() hooks
+on ARM. The remainder of this section uses examples from the ARM
+implementation, but all architectures will do pretty much the same
+thing when using a DT.
+
+As can be guessed by the names, .init_early() is used for any machine-
+specific setup that needs to be executed early in the boot process,
+and .init_irq() is used to set up interrupt handling. Using a DT
+doesn't materially change the behaviour of either of these functions.
+If a DT is provided, then both .init_early() and .init_irq() are able
+to call any of the DT query functions (of_* in include/linux/of*.h) to
+get additional data about the platform.
+
+The most interesting hook in the DT context is .init_machine() which
+is primarily responsible for populating the Linux device model with
+data about the platform. Historically this has been implemented on
+embedded platforms by defining a set of static clock structures,
+platform_devices, and other data in the board support .c file, and
+registering it en-masse in .init_machine(). When DT is used, then
+instead of hard coding static devices for each platform, the list of
+devices can be obtained by parsing the DT, and allocating device
+structures dynamically.
+
+The simplest case is when .init_machine() is only responsible for
+registering a block of platform_devices. A platform_device is a concept
+used by Linux for memory or I/O mapped devices which cannot be detected
+by hardware, and for 'composite' or 'virtual' devices (more on those
+later). While there is no 'platform device' terminology for the DT,
+platform devices roughly correspond to device nodes at the root of the
+tree and children of simple memory mapped bus nodes.
+
+About now is a good time to lay out an example. Here is part of the
+device tree for the NVIDIA Tegra board::
+
+ /{
+ compatible = "nvidia,harmony", "nvidia,tegra20";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ interrupt-parent = <&intc>;
+
+ chosen { };
+ aliases { };
+
+ memory {
+ device_type = "memory";
+ reg = <0x00000000 0x40000000>;
+ };
+
+ soc {
+ compatible = "nvidia,tegra20-soc", "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ intc: interrupt-controller@50041000 {
+ compatible = "nvidia,tegra20-gic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x50041000 0x1000>, < 0x50040100 0x0100 >;
+ };
+
+ serial@70006300 {
+ compatible = "nvidia,tegra20-uart";
+ reg = <0x70006300 0x100>;
+ interrupts = <122>;
+ };
+
+ i2s1: i2s@70002800 {
+ compatible = "nvidia,tegra20-i2s";
+ reg = <0x70002800 0x100>;
+ interrupts = <77>;
+ codec = <&wm8903>;
+ };
+
+ i2c@7000c000 {
+ compatible = "nvidia,tegra20-i2c";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x7000c000 0x100>;
+ interrupts = <70>;
+
+ wm8903: codec@1a {
+ compatible = "wlf,wm8903";
+ reg = <0x1a>;
+ interrupts = <347>;
+ };
+ };
+ };
+
+ sound {
+ compatible = "nvidia,harmony-sound";
+ i2s-controller = <&i2s1>;
+ i2s-codec = <&wm8903>;
+ };
+ };
+
+At .init_machine() time, Tegra board support code will need to look at
+this DT and decide which nodes to create platform_devices for.
+However, looking at the tree, it is not immediately obvious what kind
+of device each node represents, or even if a node represents a device
+at all. The /chosen, /aliases, and /memory nodes are informational
+nodes that don't describe devices (although arguably memory could be
+considered a device). The children of the /soc node are memory mapped
+devices, but the codec@1a is an i2c device, and the sound node
+represents not a device, but rather how other devices are connected
+together to create the audio subsystem. I know what each device is
+because I'm familiar with the board design, but how does the kernel
+know what to do with each node?
+
+The trick is that the kernel starts at the root of the tree and looks
+for nodes that have a 'compatible' property. First, it is generally
+assumed that any node with a 'compatible' property represents a device
+of some kind, and second, it can be assumed that any node at the root
+of the tree is either directly attached to the processor bus, or is a
+miscellaneous system device that cannot be described any other way.
+For each of these nodes, Linux allocates and registers a
+platform_device, which in turn may get bound to a platform_driver.
+
+Why is using a platform_device for these nodes a safe assumption?
+Well, for the way that Linux models devices, just about all bus_types
+assume that its devices are children of a bus controller. For
+example, each i2c_client is a child of an i2c_master. Each spi_device
+is a child of an SPI bus. Similarly for USB, PCI, MDIO, etc. The
+same hierarchy is also found in the DT, where I2C device nodes only
+ever appear as children of an I2C bus node. Ditto for SPI, MDIO, USB,
+etc. The only devices which do not require a specific type of parent
+device are platform_devices (and amba_devices, but more on that
+later), which will happily live at the base of the Linux /sys/devices
+tree. Therefore, if a DT node is at the root of the tree, then it
+really probably is best registered as a platform_device.
+
+Linux board support code calls of_platform_populate(NULL, NULL, NULL, NULL)
+to kick off discovery of devices at the root of the tree. The
+parameters are all NULL because when starting from the root of the
+tree, there is no need to provide a starting node (the first NULL), a
+parent struct device (the last NULL), and we're not using a match
+table (yet). For a board that only needs to register devices,
+.init_machine() can be completely empty except for the
+of_platform_populate() call.
+
+In the Tegra example, this accounts for the /soc and /sound nodes, but
+what about the children of the SoC node? Shouldn't they be registered
+as platform devices too? For Linux DT support, the generic behaviour
+is for child devices to be registered by the parent's device driver at
+driver .probe() time. So, an i2c bus device driver will register a
+i2c_client for each child node, an SPI bus driver will register
+its spi_device children, and similarly for other bus_types.
+According to that model, a driver could be written that binds to the
+SoC node and simply registers platform_devices for each of its
+children. The board support code would allocate and register an SoC
+device, a (theoretical) SoC device driver could bind to the SoC device,
+and register platform_devices for /soc/interrupt-controller, /soc/serial,
+/soc/i2s, and /soc/i2c in its .probe() hook. Easy, right?
+
+Actually, it turns out that registering children of some
+platform_devices as more platform_devices is a common pattern, and the
+device tree support code reflects that and makes the above example
+simpler. The second argument to of_platform_populate() is an
+of_device_id table, and any node that matches an entry in that table
+will also get its child nodes registered. In the Tegra case, the code
+can look something like this::
+
+ static void __init harmony_init_machine(void)
+ {
+ /* ... */
+ of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL);
+ }
+
+"simple-bus" is defined in the Devicetree Specification as a property
+meaning a simple memory mapped bus, so the of_platform_populate() code
+could be written to just assume simple-bus compatible nodes will
+always be traversed. However, we pass it in as an argument so that
+board support code can always override the default behaviour.
+
+[Need to add discussion of adding i2c/spi/etc child devices]
+
+Appendix A: AMBA devices
+------------------------
+
+ARM Primecells are a certain kind of device attached to the ARM AMBA
+bus which include some support for hardware detection and power
+management. In Linux, struct amba_device and the amba_bus_type is
+used to represent Primecell devices. However, the fiddly bit is that
+not all devices on an AMBA bus are Primecells, and for Linux it is
+typical for both amba_device and platform_device instances to be
+siblings of the same bus segment.
+
+When using the DT, this creates problems for of_platform_populate()
+because it must decide whether to register each node as either a
+platform_device or an amba_device. This unfortunately complicates the
+device creation model a little bit, but the solution turns out not to
+be too invasive. If a node is compatible with "arm,primecell", then
+of_platform_populate() will register it as an amba_device instead of a
+platform_device.
