+ps8640-bridge bindings
+
+Required properties:
+	- compatible: "parade,ps8640"
+	- reg: first i2c address of the bridge
+	- power-gpios: OF device-tree gpio specification for power pin.
+	- reset-gpios: OF device-tree gpio specification for reset pin.
+	- mode-sel-gpios: OF device-tree gpio specification for mode-sel pin.
+	- ps8640-1v2-supply: OF device-tree regulator specification for 1v2.
+	- ps8640-3v3-supply: OF device-tree regulator specification for 3v3.
+
+Optional properties:
+	- video interfaces: Device node can contain video interface port
+			    nodes for panel according to [1].
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt

+Example:

+		reg = <0x18>;
+		power-gpios = <&pio 116 GPIO_ACTIVE_HIGH>;
+		reset-gpios = <&pio 115 GPIO_ACTIVE_HIGH>;
+		mode-sel-gpios = <&pio 92 GPIO_ACTIVE_HIGH>;
+		ps8640-1v2-supply = <&ps8640_fixed_1v2>;
