+Required properties:
+	- compatible: "parade,ps8640"
+	- reg: first page address of the bridge.
+	- sleep-gpios: OF device-tree gpio specification for PD pin.
+	- reset-gpios: OF device-tree gpio specification for reset pin.
+	- vdd12-supply: OF device-tree regulator specification for 1.2V power.
+	- vdd33-supply: OF device-tree regulator specification for 3.3V power.
+	- ports: The device node can contain video interface port nodes per
+		 the video-interfaces bind[1]. For port@0,set the reg = <0> as
+		 ps8640 dsi in and port@1,set the reg = <1> as ps8640 eDP out.
+
+Optional properties:
+	- mode-sel-gpios: OF device-tree gpio specification for mode-sel pin.
