88pm860x-backlight bindings

Optional properties:

  - maxim,max8925-dual-string: whether support dual string

Example:

	backlights {

		maxim,max8925-dual-string = <0>;

	};

* Maxim max8925 Power Management IC

Required parent device properties:

- compatible : "maxim,max8925"

- reg : the I2C slave address for the max8925 chip

- interrupts : IRQ line for the max8925 chip

- interrupt-controller: describes the max8925 as an interrupt

  controller (has its own domain)

- #interrupt-cells : should be 1.

	- The cell is the max8925 local IRQ number

Optional parent device properties:

- maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in

  interrupts property, the other is indicated here.

max8925 consists of a large and varied group of sub-devices:

Device			 Supply Names	 Description

------			 ------------	 -----------

max8925-onkey		:		: On key

max8925-rtc		:		: RTC

max8925-regulator	:		: Regulators

max8925-backlight	:		: Backlight

max8925-touch		:		: Touchscreen

max8925-power		:		: Charger

Example:

	pmic: max8925@3c {

		compatible = "maxim,max8925";

		reg = <0x3c>;

		interrupts = <1>;

		interrupt-parent = <&intcmux4>;
