SPDX-License-Identifier: GPL-2.0 + +=================== +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.

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. + + The root node indicates the CPU SoC on the core tile, and this + is a daughterboard to the main motherboard. The name used in the compatible + string shall match the name given in the core tile's technical reference + manual, followed by "arm,vexpress" as an additional compatible value. If + further subvariants are released of the core tile, even more fine-granular + compatible strings with up to three compatible strings are used. + +properties: + $nodename: + const: '/' + compatible: + oneOf: + - description: CoreTile Express A9x4 (V2P-CA9) has 4 Cortex A9 CPU cores + in MPCore configuration in a test chip on the core tile.

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.

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). diff --git a/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml b/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml new file mode 100644 index 000000000..aa1d4afbc --- /dev/null +++ b/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml @@ -0,0 +1,25 @@ +# SPDX-License-Identifier: GPL-2.0 +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/arm/socionext/milbeaut.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Milbeaut platforms device tree bindings + +maintainers: + - Taichi Sugaya + - Takao Orito + +properties: + $nodename: + const: '/' + compatible: + oneOf: + - items: + - enum: + - socionext,milbeaut-m10v-evb + - const: socionext,sc2000a + +additionalProperties: true + +... diff --git a/Documentation/devicetree/bindings/arm/socionext/socionext,uniphier-system-cache.yaml b/Documentation/devicetree/bindings/arm/socionext/socionext,uniphier-system-cache.yaml new file mode 100644 index 000000000..6096c082d --- /dev/null +++ b/Documentation/devicetree/bindings/arm/socionext/socionext,uniphier-system-cache.yaml @@ -0,0 +1,101 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/arm/socionext/socionext,uniphier-system-cache.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: UniPhier outer cache controller + +description: | + UniPhier ARM 32-bit SoCs are integrated with a full-custom outer cache + controller system.

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.

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.

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.

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.

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 + 0xffb90000 0x20>; + interrupts = <0 175 4>; + }; + + fpga_bridge0: fpga-bridge@ff400000 { + compatible = "altr,socfpga-lwhps2fpga-bridge"; + reg = <0xff400000 0x100000>; + resets = <&rst LWHPS2FPGA_RESET>; + clocks = <&l4_main_clk>; + + #address-cells = <1>; + #size-cells = <1>; + ranges; + + fpga_region0: fpga-region0 { + compatible = "fpga-region"; + fpga-mgr = <&fpga_mgr>; + }; + }; + + fpga_bridge1: fpga-bridge@ff500000 { + compatible = "altr,socfpga-hps2fpga-bridge"; + reg = <0xff500000 0x10000>; + resets = <&rst HPS2FPGA_RESET>; + clocks = <&l4_main_clk>; + }; + +Overlay contains: + +/dts-v1/; +/plugin/; + +&fpga_region0 { + #address-cells = <1>; + #size-cells = <1>; + + firmware-name = "soc_system.rbf"; + fpga-bridges = <&fpga_bridge1>; + ranges = <0x20000 0xff200000 0x100000>, + <0x0 0xc0000000 0x20000000>; + + gpio@10040 { + compatible = "altr,pio-1.0"; + reg = <0x10040 0x20>; + altr,ngpio = <4>; + #gpio-cells = <2>; + clocks = <2>; + gpio-controller; + }; + + 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: Full Reconfiguration without Bridges +========================================================= + +Live Device Tree contains: + fpga_mgr0: fpga-mgr@f8007000 { + compatible = "xlnx,zynq-devcfg-1.0"; + reg = <0xf8007000 0x100>; + interrupt-parent = <&intc>; + interrupts = <0 8 4>; + clocks = <&clkc 12>; + clock-names = "ref_clk"; + syscon = <&slcr>; + }; + + fpga_region0: fpga-region0 { + compatible = "fpga-region"; + fpga-mgr = <&fpga_mgr0>; + #address-cells = <0x1>; + #size-cells = <0x1>; + ranges; + }; + +DT Overlay contains: + +/dts-v1/; +/plugin/; + +&fpga_region0 { + #address-cells = <1>; + #size-cells = <1>; + + firmware-name = "zynq-gpio.bin"; + + gpio1: gpio@40000000 { + compatible = "xlnx,xps-gpio-1.00.a"; + reg = <0x40000000 0x10000>; + gpio-controller; + #gpio-cells = <0x2>; + xlnx,gpio-width= <0x6>; + }; +}; + +Device Tree Example: Full Reconfiguration to add PRR's +====================================================== + +The base FPGA Region is specified similar to the first example above. + +This example programs the FPGA to have two regions that can later be partially +configured.

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@ { + /* this node defines the FSI slave device, and is handled + * entirely with FSI core code */ + + fsi-slave-engine@ { + /* this node defines the engine endpoint & address range, which + * is bound to the relevant fsi device driver */ + ... + }; + + fsi-slave-engine@ { + ... + }; + + }; + }; + +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.

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. This name should be the most meaningful producer name +for the system, such as a rail name indicating the usage. Package names +such as pin name are discouraged: such lines have opaque names (since they +are by definition generic 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. Placeholders are discouraged: +rather use the "" (blank string) if the use of the GPIO line is undefined +in your design. 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 named are less than ngpios) will still 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 and 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 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 + 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.

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.

These +properties contain a list of interrupt specifiers, one per output interrupt.

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).

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 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.

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 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.

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 { + spi0 { + 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 = , , ...; + }; + }; + + 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. + +properties: + function: + $ref: /schemas/types.yaml#/definitions/string + description: The mux function to select + + pins: + oneOf: + - $ref: /schemas/types.yaml#/definitions/uint32-array + - $ref: /schemas/types.yaml#/definitions/string-array + description: + The list of pin identifiers that properties in the node apply to.

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 = ; + The reg property should specificy 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 assocativity 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";

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 = ; +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.

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: + 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.

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 +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. diff --git a/Documentation/devicetree/bindings/powerpc/fsl/pamu.txt b/Documentation/devicetree/bindings/powerpc/fsl/pamu.txt new file mode 100644 index 000000000..b21ab85de --- /dev/null +++ b/Documentation/devicetree/bindings/powerpc/fsl/pamu.txt @@ -0,0 +1,148 @@ +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 : + First entry is a version-specific string, such as + "fsl,pamu-v1.0".

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.

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.

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 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. diff --git a/Documentation/devicetree/bindings/sound/fsl,xcvr.yaml b/Documentation/devicetree/bindings/sound/fsl,xcvr.yaml new file mode 100644 index 000000000..223b8ea69 --- /dev/null +++ b/Documentation/devicetree/bindings/sound/fsl,xcvr.yaml @@ -0,0 +1,104 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/sound/fsl,xcvr.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NXP Audio Transceiver (XCVR) Controller + +maintainers: + - Viorel Suman + +description: | + NXP XCVR (Audio Transceiver) is a on-chip functional module + that allows CPU to receive and transmit digital audio via + HDMI2.1 eARC, HDMI1.4 ARC and SPDIF. + +properties: + $nodename: + pattern: "^xcvr@.*" + + compatible: + enum: + - fsl,imx8mp-xcvr + + reg: + items: + - description: 20K RAM for code and data + - description: registers space + - description: RX FIFO address + - description: TX FIFO address + + reg-names: + items: + - const: ram + - const: regs + - const: rxfifo + - const: txfifo + + interrupts: + maxItems: 1 + + clocks: + items: + - description: Peripheral clock + - description: PHY clock + - description: SPBA clock + - description: PLL clock + + clock-names: + items: + - const: ipg + - const: phy + - const: spba + - const: pll_ipg + + dmas: + items: + - description: DMA controller phandle and request line for RX + - description: DMA controller phandle and request line for TX + + dma-names: + items: + - const: rx + - const: tx + + resets: + maxItems: 1 + +required: + - compatible + - reg + - reg-names + - interrupts + - clocks + - clock-names + - dmas + - dma-names + - resets + +additionalProperties: false + +examples: + - | + #include + #include + #include + + xcvr: xcvr@30cc0000 { + compatible = "fsl,imx8mp-xcvr"; + reg = <0x30cc0000 0x800>, + <0x30cc0800 0x400>, + <0x30cc0c00 0x080>, + <0x30cc0e00 0x080>; + reg-names = "ram", "regs", "rxfifo", "txfifo"; + interrupts = <0x0 128 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&audiomix_clk IMX8MP_CLK_AUDIOMIX_EARC_IPG>, + <&audiomix_clk IMX8MP_CLK_AUDIOMIX_EARC_PHY>, + <&audiomix_clk IMX8MP_CLK_AUDIOMIX_SPBA2_ROOT>, + <&audiomix_clk IMX8MP_CLK_AUDIOMIX_AUDPLL_ROOT>; + clock-names = "ipg", "phy", "spba", "pll_ipg"; + dmas = <&sdma2 30 2 0>, <&sdma2 31 2 0>; + dma-names = "rx", "tx"; + resets = <&audiomix_reset 0>; + }; diff --git a/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt b/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt new file mode 100644 index 000000000..8b4f4015c --- /dev/null +++ b/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt @@ -0,0 +1,115 @@ +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.

SPDX-License-Identifier: GPL-2.0 + +========================================== +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: : ..." + + 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 "" may be used in compatible strings, as in + the following example: + + - compatible: Must contain '"nvidia,-pcie", + "nvidia,tegra20-pcie"' where is tegra30, tegra132, ... + + As in the above example, the known values of "" 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.

It indicates gpu clock throttling depth and can be + programmed to any of the following values which represent a throttling + percentage: + TEGRA_SOCTHERM_THROT_LEVEL_NONE (0%) + TEGRA_SOCTHERM_THROT_LEVEL_LOW (50%), + TEGRA_SOCTHERM_THROT_LEVEL_MED (75%), + TEGRA_SOCTHERM_THROT_LEVEL_HIGH (85%). + - #cooling-cells: Should be 1. This cooling device only support on/off state. + For a description of this property see: + Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml + + Optional properties: The following properties are T210 specific and + valid only for OCx throttle events. + - nvidia,count-threshold: Specifies the number of OC events that are + required for triggering an interrupt. Interrupts are not triggered if + the property is missing. A value of 0 will interrupt on every OC alarm. + - nvidia,polarity-active-low: Configures the polarity of the OC alaram + signal. If present, this means assert low, otherwise assert high. + - nvidia,alarm-filter: Number of clocks to filter event. When the filter + expires (which means the OC event has not occurred for a long time), + the counter is cleared and filter is rearmed. Default value is 0. + - nvidia,throttle-period-us: Specifies the number of uSec for which + throttling is engaged after the OC event is deasserted. Default value + is 0. + +Optional properties: +- nvidia,thermtrips : When present, this property specifies the temperature at + which the soctherm hardware will assert the thermal trigger signal to the + Power Management IC, which can be configured to reset or shutdown the device. + It is an array of pairs where each pair represents a tsensor id followed by a + temperature in milli Celcius. In the absence of this property the critical + trip point will be used for thermtrip temperature. + +Note: +- the "critical" type trip points will be used to set the temperature at which +the SOC_THERM hardware will assert a thermal trigger if the "nvidia,thermtrips" +property is missing. When the thermtrips property is present, the breach of a +critical trip point is reported back to the thermal framework to implement +software shutdown. + +- the "hot" type trip points will be set to SOC_THERM hardware as the throttle +temperature.

SPDX-License-Identifier: GPL-2.0 + +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.
