+- 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
