For example MIXer, it is like below.
If you removes "dup_codec", it breaks MIXer and/or TDM split mode.

	CPU0  ---+---- DAI
	         |
	CPU1  ---+

	cpu {
		ports {
			port@0 {
				cpu_0: endpoint {
					remote-endpoint = <&codec_0>;
				};
			};
			port@1 {
				cpu_1: endpoint {
					remote-endpoint = <&codec_1>;
				};
			};
		};
	};

	codec {
		port {
			codec_0: endpoint {
				remote-endpoint = <&cpu_0>;
			};
			codec_1: endpoint {
				remote-endpoint = <&cpu_1>;
			};
		}
	};

Thank you for your help !!

Best regards
