Wow!! Thanks !!
it makes new OF-graph easier !!

If my understanding was correct, this is good ?

Card {
	ports {
		port@0 {
			card-dsp: endpoint {
				remote-endpoint = <&dsp>;
			};
		};
		port@1 {
			card-codec: endpoint {
				remote-endpoint = <&codec>;
			};
		}
	}
}

DSP {
	port {
		dsp: endpoint {
			remote-endpoint = <&card-dsp>;
		}
	}
}

Codec {
	port {
		codec: endpoint {
			remote-endpoint = <&card-codec>;
		}
	}
}
