I see. How these IDs will be added?
Will does are given by the core automatically based on device load order, or
will the machine driver have the ability to specify the ID for a codec?
Another question: how the PCM interfaces will be seen when we have multiple
codec/dai in a card?
I suppose we will have multiple PCMs in a card, when we have multiple codec
(multiple dai pairs)..?
