The contents seem ok (at least the audio related).

But it would have been better if you had broken the patch into three
   a) Regulator support adding  (90% of the code and should have been
CC'd to Mark and Liam as well)
   b) I2C related.
   c) Audio related

Preferably further divided for each machine.
