1led-backlight bindings 2 3This binding is used to describe a basic backlight device made of LEDs. 4It can also be used to describe a backlight device controlled by the output of 5a LED driver. 6 7Required properties: 8 - compatible: "led-backlight" 9 - leds: a list of LEDs 10 11Optional properties: 12 - brightness-levels: Array of distinct brightness levels. The levels must be 13 in the range accepted by the underlying LED devices. 14 This is used to translate a backlight brightness level 15 into a LED brightness level. If it is not provided, the 16 identity mapping is used. 17 18 - default-brightness-level: The default brightness level. 19 20Example: 21 22 backlight { 23 compatible = "led-backlight"; 24 25 leds = <&led1>, <&led2>; 26 brightness-levels = <0 4 8 16 32 64 128 255>; 27 default-brightness-level = <6>; 28 }; 29
