1 * Hannstar CABC device tree bindings
3 The Hannstar CABC function may turn a display plane's backlight
4 automatically according to the content shown on the plane. The
5 function is controlled(enabled/disabled) by a GPIO.
8 - compatible : Should be "hannstar,cabc".
10 Each standalone CABC gpio is represented as a sub-node of "hannstar_cabc":
11 Required subnode properties:
12 - gpios: OF device-tree gpio specification.
14 Optional subnode properties:
15 - cabc-enable: Provide this bool property if you want to enable the CABC feature.
19 compatible = "hannstar,cabc";
22 gpios = <&gpio6 15 GPIO_ACTIVE_HIGH>;
26 gpios = <&gpio6 16 GPIO_ACTIVE_HIGH>;
