+* Texas Instruments - lm3601x Single-LED Flash Driver
+
+The LM3601X are ultra-small LED flash drivers that
+provide a high level of adjustability.
+
+Required properties:
+       - compatible : Can be one of the following
+               "ti,lm36010"
+               "ti,lm36011"
+       - reg : I2C slave address
+       - #address-cells : 1
+       - #size-cells : 0
+
+Required child properties:
+       - reg : 0 - Indicates a IR mode
+               1 - Indicates a Torch (white LED) mode
+
+Required properties for flash LED child nodes:
+       See Documentation/devicetree/bindings/leds/common.txt
+       - flash-max-microamp : Range from 11mA - 1.5A
+       - flash-max-timeout-us : Range from 40ms - 1600ms
+       - led-max-microamp : Range from 2.4mA - 376mA
+
+Optional child properties:
+       - label : see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+led-controller@64 {
+       compatible = "ti,lm36010";
+       #address-cells = <1>;
+       #size-cells = <0>;
+       reg = <0x64>;
+
+       led@0 {
+               reg = <1>;
+               label = "white:torch";
+               led-max-microamp = <376000>;
+               flash-max-microamp = <1500000>;
+               flash-max-timeout-us = <1600000>;
+       };
