Merge tag 'regmap-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "A couple of new features this time around, nothing that should have
  any impact on most users:

   - Cleanups and optimization of the path for reading back the register
     defaults from the hardware at startup, reducing boot times for
     devices that use this (most don't, either populating on demand or
     providing defaults).
   - A bus implementation for AC'97 devices"
