Merge tag 'regulator-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is quite a quiet release in terms of volume of patches but it
  includes a couple of really nice core changes - the work Sascha has
  done in particular is something I've wanted to get done for a long
  time but just never got round to myself.

  Highlights include:

   - Support from Sascha Hauer for setting the voltage of parent
     supplies based on requests from their children.  This is used both
     to allow set_voltage() to work through a dumb switch and to improve
     the efficiency of systems where DCDCs are used to supply LDOs by
     minimising the voltage drop over the LDOs.

   - Removal of regulator_list by Tomeu Vizoso, meaning we're not
     duplicating the device list maintained by the driver core.

   - Support for Wolfson/Cirrus WM8998 and WM1818"
