v7 - Removed led-sources in favor of reg, fixed malformatted ranges - https://patchwork.kernel.org/patch/10401435/

v6 - Removed multiple led child nodes, fixed example to display micro ranges
for corresponding child nodes and added led-sources to define the current driver -
https://patchwork.kernel.org/patch/10392121/
v5 - No changes - https://patchwork.kernel.org/patch/10391743/
v4 - Added " " around "=", changed strobe to flash on label, removed "support and
register" comment and change ir lable to ir:torch - See v2 patchworks for comments
v3 - Removed wildcard compatible - https://patchwork.kernel.org/patch/10386241/

+* 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>;
+	};
