The ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed
for portable device. It converts MIPI to DisplayPort 1.3 4K.

You can add support to your board with binding.

Example:
	anx7625_bridge: encoder@58 {
		compatible =3D "analogix,anx7625";
		reg =3D <0x58>;
		status =3D "okay";
		panel-flags =3D <1>;
		enable-gpios =3D <&pio 45 GPIO_ACTIVE_HIGH>;
		reset-gpios =3D <&pio 73 GPIO_ACTIVE_HIGH>;
		#address-cells =3D <1>;
		#size-cells =3D <0>;

		port@0 {
		  reg =3D <0>;
		  anx_1_in: endpoint {
		    remote-endpoint =3D <&mipi_dsi>;
		  };
		};

		port@2 {
		  reg =3D <2>;
		  anx_1_out: endpoint {
		    remote-endpoint =3D <&panel_in>;
		  };
		};
	};
