but IMO the FE DAIs are a negligible overhead compared to the routing matrix and the many BE DAIs that are really never going to be used (because nothing is physically connected to the ports).
Two things, one unnecessary mixers, second thing is we need to know how many FE dais are in the system, which should be derived from the number of dai child nodes. These can potentially be SoC specific or firmware specific.
You shouldn't be worrying about unused mixers, ideally we'd be walking the DAPM graph and masking things - this isn't something that should be open coded at individual driver levels.
