I agree in general and thought about alternatives as well, but in this
case, it turns out to be a thing the aic3x driver is responsible to as
the registers in questions are purely in its scope. So the idea is to
set up the GPIO's functions via alsa controls and handle its events in
some board-related code as this is really not abstractable. One could,
however, do this setup in machine-related code within the asoc
environment.

My changes don't cast any problems on the existing implementation
either, so I would suggest to just take this patch until someone comes
up with a more suitable solution :)

Best regards,
Daniel
