+Binding for ArcticSand arc2c0608 LED driver
+
+Required properties:
+- compatible: should be "arc,arc2c0608"
+- reg: slave address
+
+Optional properties:
+- default-brightness: brightness value on boot, value from: 0-4095
+- label: The name of the backlight device
+			See Documentation/devicetree/bindings/leds/common.txt
+- led-sources: List of enabled channels from 0 to 5.
+			See Documentation/devicetree/bindings/leds/common.txt

+Example:
+
+arc2c0608@30 {
+	compatible = "arc,arc2c0608";
+	reg = <0x30>;
+	default-brightness = <500>;
+	label = "lcd-backlight";
+	linux,default-trigger = "backlight";
+	led-sources = <0 1 2 5>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+	prog@6 {
