Resubmition of arcxcnn backliught driver addressing the naming convention
concerns raised by Rob H. Note that all the device tree properties are
determined by the board design or IC EPROM settings and are not intended
to be user adjustable.

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