Yes. For the Cubox, the card will be described by something like:
sound {
compatible = "simple-audio";
audio-controller = <&audio1>;
audio-codec = <&spdif>;
codec-dai-name = "dit-hifi";
};
with:
spdif: spdif {
compatible = "linux,spdif-dit";
};
Then, the audio driver will know about s/pdif on the first open.
