+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>;
