+* 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
+
+Example, based on mpc823:
+
+ i2c@860 {

+* 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>;
+ };
+ };
+
+* QE Firmware Node
+
+This node defines a firmware binary that is embedded in the device tree, for
+the purpose of passing the firmware from bootloader to the kernel, or from
+the hypervisor to the guest.
+
+The firmware node itself contains the firmware binary contents, a compatible
+property, and any firmware-specific properties. The node should be placed
+inside a QE node that needs it. Doing so eliminates the need for a
+fsl,firmware-phandle property. Other QE nodes that need the same firmware
+should define an fsl,firmware-phandle property that points to the firmware node
+in the first QE node.
+
+The fsl,firmware property can be specified in the DTS (possibly using incbin)
+or can be inserted by the boot loader at boot time.
+
+Required properties:
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: A standard property. Specify a string that indicates what
+ kind of firmware it is. For QE, this should be "fsl,qe-firmware".
+
+ - fsl,firmware
+ Usage: required
+ Value type: <prop-encoded-array>, encoded as an array of bytes
+ Definition: A standard property. This property contains the firmware
+ binary "blob".
+
+Example:
+ qe1@e0080000 {
+ compatible = "fsl,qe";
+ qe_firmware:qe-firmware {
+ compatible = "fsl,qe-firmware";
+ fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
+ };
+ ...
+ };
+
+ qe2@e0090000 {
+ compatible = "fsl,qe";
+ fsl,firmware-phandle = <&qe_firmware>;
+ ...
+ };

+* Uploaded QE firmware
+
+ If a new firmware has been uploaded to the QE (usually by the
+ boot loader), then a 'firmware' child node should be added to the QE
+ node. This node provides information on the uploaded firmware that
+ device drivers may need.
+
+ Required properties:
+ - id: The string name of the firmware. This is taken from the 'id'
+ member of the qe_firmware structure of the uploaded firmware.
+ Device drivers can search this string to determine if the
+ firmware they want is already present.
+ - extended-modes: The Extended Modes bitfield, taken from the
+ firmware binary. It is a 64-bit number represented
+ as an array of two 32-bit numbers.
+ - virtual-traps: The virtual traps, taken from the firmware binary.
+ It is an array of 8 32-bit numbers.
+
+Example:

+ id = "Soft-UART";
+ extended-modes = <0 0>;
+ virtual-traps = <0 0 0 0 0 0 0 0>;

+* UCC (Unified Communications Controllers)
+
+Required properties:
+- device_type : should be "network", "hldc", "uart", "transparent"
+ "bisync", "atm", or "serial".
+- compatible : could be "ucc_geth" or "fsl_atm" and so on.
+- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
+- reg : Offset and length of the register set for the device
+- interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+- interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+- pio-handle : The phandle for the Parallel I/O port configuration.
+- port-number : for UART drivers, the port number to use, between 0 and 3.
+ This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
+ The port number is added to the minor number of the device. Unlike the
+ CPM UART driver, the port-number is required for the QE UART driver.
+- soft-uart : for UART drivers, if specified this means the QE UART device
+ driver should use "Soft-UART" mode, which is needed on some SOCs that have
+ broken UART hardware. Soft-UART is provided via a microcode upload.
+- rx-clock-name: the UCC receive clock source
+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- tx-clock-name: the UCC transmit clock source
+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+The following two properties are deprecated. rx-clock has been replaced
+with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
+Drivers that currently use the deprecated properties should continue to
+do so, in order to support older device trees, but they should be updated
+to check for the new properties first.
+- rx-clock : represents the UCC receive clock source.
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+- tx-clock: represents the UCC transmit clock source;
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+
+Required properties for network device_type:
+- mac-address : list of bytes representing the ethernet address.
+- phy-handle : The phandle for the PHY connected to this controller.
+
+Recommended properties:
+- phy-connection-type : a string naming the controller/PHY interface type,
+ i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id" (Internal
+ Delay), "rgmii-txid" (delay on TX only), "rgmii-rxid" (delay on RX only),
+ "tbi", or "rtbi".
+
+Example:
+ ucc@2000 {
+ device_type = "network";
+ compatible = "ucc_geth";
+ cell-index = <1>;
+ reg = <2000 200>;
+ interrupts = <a0 0>;
+ interrupt-parent = <700>;
+ mac-address = [ 00 04 9f 00 23 23 ];
+ rx-clock = "none";
+ tx-clock = "clk9";
+ phy-handle = <212000>;
+ phy-connection-type = "gmii";
+ pio-handle = <140001>;
