powerpc: add FHCI USB, FSL MCU, FSL UPM and GPIO LEDs bindings

* USB (Universal Serial Bus Controller)

Freescale QUICC Engine USB Controller

Required properties:

- compatible : could be "qe_udc" or "fhci-hcd".

- mode : the could be "host" or "slave".

- 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.

- compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb".

- reg : the first two cells should contain usb registers location and

  length, the next two two cells should contain PRAM location and

  length.

- interrupts : should contain USB interrupt.

- interrupt-parent : interrupt source phandle.

- fsl,fullspeed-clock : specifies the full speed USB 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

- fsl,lowspeed-clock : specifies the low speed USB 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

- hub-power-budget : USB power budget for the root hub, in mA.

- gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,

  USBRN, SPEED (optional), and POWER (optional).

Example:

Example(slave):

usb@6c0 {

		compatible = "qe_udc";

		reg = <6c0 40>;

		interrupts = <8b 0>;

		interrupt-parent = <700>;

		mode = "slave";

	compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";

	reg = <0x6c0 0x40 0x8b00 0x100>;

	interrupts = <11>;

	interrupt-parent = <&qeic>;

	fsl,fullspeed-clock = "clk21";

	gpios = <&qe_pio_b  2 0 /* USBOE */

		 &qe_pio_b  3 0 /* USBTP */

		 &qe_pio_b  8 0 /* USBTN */

		 &qe_pio_b  9 0 /* USBRP */

		 &qe_pio_b 11 0 /* USBRN */

		 &qe_pio_e 20 0 /* SPEED */

		 &qe_pio_e 21 0 /* POWER */>;

};

Freescale MPC8349E-mITX-compatible Power Management Micro Controller Unit (MCU)

Required properties:

- compatible : "fsl,<mcu-chip>-<board>", "fsl,mcu-mpc8349emitx".

- reg : should specify I2C address (0x0a).

- #gpio-cells : should be 2.

- gpio-controller : should be present.

Example:

mcu@0a {

	#gpio-cells = <2>;

	compatible = "fsl,mc9s08qg8-mpc8349emitx",

		     "fsl,mcu-mpc8349emitx";

	reg = <0x0a>;

	gpio-controller;

};

Freescale Localbus UPM programmed to work with NAND flash

Required properties:

- compatible : "fsl,upm-nand".

- reg : should specify localbus chip select and size used for the chip.

- fsl,upm-addr-offset : UPM pattern offset for the address latch.

- fsl,upm-cmd-offset : UPM pattern offset for the command latch.

- gpios : may specify optional GPIO connected to the Ready-Not-Busy pin.

Example:

upm@1,0 {

	compatible = "fsl,upm-nand";

	reg = <1 0 1>;

	fsl,upm-addr-offset = <16>;

	fsl,upm-cmd-offset = <8>;

	gpios = <&qe_pio_e 18 0>;

	flash {

		#address-cells = <1>;

		#size-cells = <1>;

		compatible = "...";

		partition@0 {

			...

		};

	};

};

LED connected to GPIO

Required properties:

- compatible : should be "gpio-led".

- label : (optional) the label for this LED. If omitted, the label is

  taken from the node name (excluding the unit address).

- gpios : should specify LED GPIO.

Example:

led@0 {

	compatible = "gpio-led";

	label = "hdd";

	gpios = <&mcu_pio 0 1>;

};
