The tlv320 driver in the development branch is for (accoding to in-code
comments the TLV320AIC24K and TLV320AIC14K and isn't really a generic
one, unfortunately.  There are drivers for the tlv320aic3x and the
tlv320aic26 (the latter has been posted to the list a few times in the
past few days) - I don't know how similar either of those are.

It needs some updates for at least coding style and renaming to
something more specific to the chips it controls.  Unfortunately the
original author appears not to be working on it any more.
