I still don't understand your problem. You want something like:

	audio-ports = <	TDA998x_SPDIF	0x04
			TDA998x_I2S	0x03>;

and the graph definition would be:

	port at 03 {
		reg = <0x03>;
		port-type = "audio-i2s";
		...
	};

	port at 04 {
		reg = <0x04>;
		port-type = "audio-spdif";
		...
	};

Apart the syntax, I don't really see the difference.
