This looks like it should be fairly straightforward to support
within ASoC without too much work, and since it's in the audio
path it should probably be referenced from the sound card it'll
end up having an ABI impact on the card.  Take a look at wm9090
for a moderately complex example of an analogue only device
(which this appears to be in terms of system integration).
