+* 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>;
+ };
+ };
