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>;
}
}
}
