The most noticable changes in the ASoC core for this release are:

 - Redone power sequencing code, giving shorter power sequences which
   should reduce the effect of any artifacts that exist.

 - Reporting of power management decisions via debugfs, enabling much
   easier diagnosis of path setup problems.

 - Beginning of work to factor out the register access and caching code
   from the individual CODEC drivers into a shared file.  This needs to
   be rolled out over more CODEC drivers.
