+* Texas Instruments - LM3692x Highly Efficient White LED Driver
+
+The LM3692x is an ultra-compact, highly efficient,
+white-LED driver designed for LCD display backlighting.
+
+The main difference between the LM36922 and LM36923 is the number of
+LED strings it supports. The LM36922 supports two strings while the LM36923
+supports three strings.
+
+Required properties:
+ - compatible:
+ "ti,lm36922"
+ "ti,lm36923"
+ - reg : I2C slave address
+ - #address-cells : 1
+ - #size-cells : 0
+
+Optional properties:
+ - enable-gpios : gpio pin to enable/disable the device.
+ - vled-supply : LED supply
+
+Required child properties:
+ - reg : 0
+
+Optional child properties:
+ - label : see Documentation/devicetree/bindings/leds/common.txt
+ - linux,default-trigger :
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+led-controller@36 {
+ compatible = "ti,lm3692x";
+ reg = <0x36>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+ vled-supply = <&vbatt>;
+
+ led@0 {
+ reg = <0>;
+ label = "white:backlight_cluster";
+ linux,default-trigger = "backlight";
+ };
+}
