| 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>; |
| }; |
