+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].

+Example:
+ edp-bridge@18 {
+ compatible = "parade,ps8640";
+ 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>;
+ ps8640-3v3-supply = <&mt6397_vgp2_reg>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ ps8640_in: endpoint {
+ remote-endpoint = <&dsi0_out>;

+
+ port@1 {
