+BMan Node
+
+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.
+
+Example of four SOC GPIO banks defined as gpio-controller nodes:
+
+ 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-num-snums: define how many serial number(SNUM) the QE can use for the
+ 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.
+
+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>;
+ }
+
+* 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
+ translation of MURAM addresses.
+- 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>;
+ };
+ };
+
+* Interrupt Controller (IC)
+
+Required properties:
+- compatible : should be "fsl,qe-ic".
+- reg : Address range of IC register set.
+- interrupts : interrupts generated by the device.
+- interrupt-controller : this device is a interrupt controller.
+
+Example:
+
+ qeic: interrupt-controller@80 {
+ interrupt-controller;
+ compatible = "fsl,qe-ic";
+ #address-cells = <0>;
+ #interrupt-cells = <1>;
+ reg = <0x80 0x80>;
+ interrupts = <95 2 0 0 94 2 0 0>;
+ };
+
+* 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".

+ 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>;

+ - 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
+
+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

+ };
+
+* 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

+optionally be encrypted. Also a non standard Dual IO SPI mode can be
+used to increase speed.
+
+IP Pairing
+
+on MT8135 the pins of some SoC internal peripherals can be on the PMIC.

+RPMH RSC:
+------------
+
+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 */
+
+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.

+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: The tuple defining the configuration of TCS.

+ WAKE_TCS
+ CONTROL_TCS
+ - Cell #2 (Number of TCS): <u32>

+- label:

+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>;

+* 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.
+
+Example:
+

+Texas Instruments TI-SCI Generic Power Domain
+---------------------------------------------
+
+Some TI SoCs contain a system controller (like the PMMC, etc...) that is
+responsible for controlling the state of the IPs that are present.
+Communication between the host processor running an OS and the system
+controller happens through a protocol known as TI-SCI [1].
+
+[1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
+
+PM Domain Node
+==============
+The PM domain node represents the global PM domain managed by the PMMC, which
+in this case is the implementation as documented by the generic PM domain
+bindings in Documentation/devicetree/bindings/power/power_domain.txt. Because
+this relies on the TI SCI protocol to communicate with the PMMC it must be a
+child of the pmmc node.
+
+Required Properties:
+--------------------
+- compatible: should be "ti,sci-pm-domain"
+- #power-domain-cells: Must be 1 so that an id can be provided in each
+ device node.
+
+Example (K2G):
+-------------
+ pmmc: pmmc {
+ compatible = "ti,k2g-sci";
+ ...
+
+ k2g_pds: power-controller {
+ compatible = "ti,sci-pm-domain";
+ #power-domain-cells = <1>;
+ };
+ };
+
+PM Domain Consumers
+===================
+Hardware blocks belonging to a PM domain should contain a "power-domains"
+property that is a phandle pointing to the corresponding PM domain node
+along with an index representing the device id to be passed to the PMMC
+for device control.
+
+Required Properties:
+--------------------
+- power-domains: phandle pointing to the corresponding PM domain node
+ and an ID representing the device.
+
+See http://processors.wiki.ti.com/index.php/TISCI#66AK2G02_Data for the list
+of valid identifiers for k2g.
+
+Example (K2G):
+--------------------
+ uart0: serial@2530c00 {
+ compatible = "ns16550a";
+ ...
+ power-domains = <&k2g_pds 0x002c>;

+Wakeup M3 IPC 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, 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.
+
+Required properties:
+--------------------
+- compatible: Should be,
+ "ti,am3352-wkup-m3-ipc" for AM33xx SoCs
+ "ti,am4372-wkup-m3-ipc" for AM43xx SoCs
+- reg: Contains the IPC register address space to communicate
+ with the Wakeup M3 processor
+- interrupts: Contains the interrupt information for the wkup_m3
+ interrupt that signals the MPU.
+- ti,rproc: phandle to the wkup_m3 rproc node so the IPC driver
+ can boot it.
+- mboxes: phandles used by IPC framework to get correct mbox
+ channel for communication. Must point to appropriate
+ mbox_wkupm3 child node.
+
+Example:
+--------
+/* AM33xx */
+ l4_wkup: l4_wkup@44c00000 {
