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>;
                }
        }
}
