[PATCH v1 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:
	anx_bridge: anx7625 at 58 {
		compatible = "analogix,anx7625";
		reg = <0x58>;
		low-power-mode = <1>;
		dsi-supported = <1>;
		dsi-channel-id = <1>;
		dsi-lanes-num = <4>;
		internal-pannel-supported = <1>;
		pon-gpios = <&gpio0 45 GPIO_ACTIVE_LOW>;
		reset-gpios = <&gpio0 73 GPIO_ACTIVE_LOW>;
		status = "okay";
		port {
			anx7625_1_in: endpoint {
				remote-endpoint = <&mipi_dsi_bridge_1>;
			};
		};
	};
