I know that it works, I have used it myself until now, but it is not 
needed and there is no driver that parses audio port endpoints. I see no 
point specifying something in the binding that is not used and there no 
specific plan to ever use it.

AFAIU my proposed binding should work equally well with simple-card, 
with or without multi-codec support.
