| * Hannstar CABC device tree bindings |
| |
| The Hannstar CABC function may turn a display plane's backlight |
| automatically according to the content shown on the plane. The |
| function is controlled(enabled/disabled) by a GPIO. |
| |
| Required properties: |
| - compatible : Should be "hannstar,cabc". |
| |
| Each standalone CABC gpio is represented as a sub-node of "hannstar_cabc": |
| Required subnode properties: |
| - gpios: OF device-tree gpio specification. |
| |
| Optional subnode properties: |
| - cabc-enable: Provide this bool property if you want to enable the CABC feature. |
| |
| Example: |
| hannstar_cabc { |
| compatible = "hannstar,cabc"; |
| |
| lvds0 { |
| gpios = <&gpio6 15 GPIO_ACTIVE_HIGH>; |
| }; |
| |
| lvds1 { |
| gpios = <&gpio6 16 GPIO_ACTIVE_HIGH>; |
| }; |
| }; |
