The LM3692x is an ultra-compact, highly efficient,

white-LED driver designed for LCD display backlighting.

LED strings it supports.  The LM36922 supports two strings while the LM36923

supports three strings.

	- vled-supply : LED supply



Required child properties:

	- reg : 0



Optional child properties:

	- label : see Documentation/devicetree/bindings/leds/common.txt

	compatible = "ti,lm3692x";

	reg = <0x36>;

	#address-cells = <1>;

	#size-cells = <0>;



	enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
