And maybe more; that's just me summarizing unconnected pins, not the datasheet. There are also cost-reduced parts with less audio capability.

I make no claim about audio expertise -- the nearest I come to it is observing a few years back that there was a huge framework hole, which ASoC seems to fill -- but I wonder if it shouldn't suffice just to provide a mask of capabilities that are wired up on a given board.
It's possible - if the differences can be handled by marking some pins as connected or disconnected and possible specifying a different system clock rate to the chip then that approach was what I was expecting. If there is more substantial differences such as having the clocking arranged differently then separate drivers start to make more sense.
