Applied - thanks for your hard work on this!  

BTW, I don't know if you noticed the DAPM changes I pushed the other
day.  One commit in particular, 452c5eaa0d5162e02ffee742ea17540887bc2904, 
might be interesting for TWL4030 - it changes things so that we're in
BIAS_ON whenever there's a bias path active, not only when there's a DAC
or ADC path.  I've got a feeling some of the pop/click stuff may mean
that's not as useful as it might've been in the past.

Since it's just a change in one parameter the driver should be able to
arrange to get that configuration value provided to it via platform
data.  It's still the same chip and needs the same driver, all that's
changing is configuration information.
