This patch looks OK, but having the DTS changes in the same patch
probably isn't a good idea. I would really like to see this series
merged for 4.11, so we can expose a good mixer interface to userspace
during the first kernel release supporting the A33 codec. That likely
means some breakage between when the asoc bits and the dts bits land
though.

Maxime, any ideas?
