-led-backlight bindings
-
-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>;
- };
