+This binding is used to describe a basic backlight device made of LEDs. +It can also be used to describe a backlight device controlled by the output of +a LED driver.

+Required properties:

• • compatible: "led-backlight"
• • leds: a list of LEDs

+Optional properties:

• • brightness-levels: Array of distinct brightness levels. The levels must be

•                   in the range accepted by the underlying LED devices.
  

•                   This is used to translate a backlight brightness level
  

•                   into a LED brightness level. If it is not provided, the
  

•                   identity mapping is used.
  

• • default-brightness-level: The default brightness level.

+Example:

• backlight {

• compatible = "led-backlight";
  

• leds = <&led1>, <&led2>;
  

• brightness-levels = <0 4 8 16 32 64 128 255>;
  

• default-brightness-level = <6>;
  

• };
