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:
	anx_bridge: anx7625@58 {
		compatible =3D "analogix,anx7625";
		reg =3D <0x58>;
		anx,low_power_mode =3D <1>;
		anx,dsi_supported =3D <1>;
		anx,dsi_channel =3D <1>;
		anx,dsi_lanes =3D <4>;
		anx,internal_pannel =3D <1>;
		anx,p-on-gpio =3D <&gpio0 45 GPIO_ACTIVE_LOW>;
		anx,reset-gpio =3D <&gpio0 73 GPIO_ACTIVE_LOW>;
		status =3D "okay";
		port {
			anx7625_1_in: endpoint {
				remote-endpoint =3D <&mipi_dsi_bridge_1>;
			};
		};
	};
