You can add support to your board with binding.

We have an example in the binding, no reason to also put in the commit msg.

Example: anx7625_bridge: encoder@58 { compatible = "analogix,anx7625"; reg = <0x58>; status = "okay"; enable-gpios = <&pio 45 GPIO_ACTIVE_HIGH>; reset-gpios = <&pio 73 GPIO_ACTIVE_HIGH>;

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

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

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

};
