Do you mean, is this OK for OF graph ?
in driver point of view, "I2S" is sound card here.

I2S {
	port {
		i2s-dsp: endpoint {
			remote-endpoint = <&dsp>;
		}
		i2s-codec: endpoint {
			remote-endpoint = <&codec>;
		}
	}
}

DSP {
	port {
		dsp: endpoint {
			remote-endpoint = <&i2s-dsp>;
		}
	}
}

Codec {
	port {
		codec: endpoint {
			remote-endpoint = <&i2s-codec>;
		}
	}
}
