+* 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
+
+Optional properties:
+	- label : see Documentation/devicetree/bindings/leds/common.txt
+	- enable-gpios : gpio pin to enable/disable the device.
+	- vled-supply : LED supply
+	- linux,default-trigger : (optional)
+	   see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+lm3692x@36 {
+	compatible = "ti,lm3692x";
+	reg = <0x36>;
+
+	enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+	vled-supply = <&vbatt>;
+
+	backlight: backlight@0 {
+		label = "backlight_cluster";
+		linux,default-trigger = "backlight";
+	};
+}
