+ps8640-bridge bindings
+
+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.
