+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.
- mode-sel-gpios: OF device-tree gpio specification for mode-sel 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> asps8640 dsi in and port@1,set the reg = <1> as ps8640 eDP out.+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
