+Binding for ArcticSand arc2c0608 LED driver
+
+Required properties:
+- compatible: should be "arctic,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
+
+- arctic,led-config-0: setting for register ILED_CONFIG_0
+- arctic,led-config-1: setting for register ILED_CONFIG_1
+- arctic,dim-freq: PWM mode frequence setting (bits [3:0] used)
+- arctic,comp-config: setting for register CONFIG_COMP
+- arctic,filter-config: setting for register FILTER_CONFIG
+- arctic,trim-config: setting for register IMAXTUNE
+
+Note: Optional properties not specified will default to values in IC EPROM
+
+Example:
+
+arc2c0608@30 {
+ compatible = "arctic,arc2c0608";
+ reg = <0x30>;
+ default-brightness = <500>;
+ label = "lcd-backlight";
+ linux,default-trigger = "backlight";
+ led-sources = <0 1 2 5>;
