    display-timings {
        ...
    };

    port@0 {
	reg = <0>;
	panel_in_lvds: endpoint {
	    remote-endpoint = <&lvds_out_panel>;
	};
    };
};

2.
panel {
    ...

    display-timings {
        ...
    };

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

	port@0 {
	    reg = <0>;
	    panel_in_lvds: endpoint {
		remote-endpoint = <&lvds_out_panel>;
	    };
