The other issue is that it's designed for high volume data and these
AUXADCs tend to be relatively slow.  That said I've had some discussions
with Jonathan about supporting these devices via IIO and he seems to be
coming round to the idea that we could integrate support.  Not sure how
fast IIO is progressing to mainline, though.
