[PATCH v9 1/2] dt-bindings: drm/bridge: anx7625: MIPI to DP transmitter binding

[Xin Ji]

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 at 58 {
		compatible = "analogix,anx7625";
		reg = <0x58>;
		status = "okay";
		enable-gpios = <&pio 45 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&pio 73 GPIO_ACTIVE_HIGH>;
		#address-cells = <1>;
		#size-cells = <0>;

		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			mipi2dp_bridge_in: port at 0 {
				reg = <0>;
				anx7625_in: endpoint {
					remote-endpoint = <&mipi_dsi>;
				};
			};

			mipi2dp_bridge_out: port at 1 {
				reg = <1>;
				anx7625_out: endpoint {
					remote-endpoint = <&panel_in>;
				};
			};
		};
	};
