Merge tag 'regulator-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into next

Pull regulator updates from Mark Brown:
 "The bulk of the changes for this release are a few new drivers however
  there are a couple of noticable core changes and the usual stream of
  cleanups and fixes:

   - move disable of unused regulators later in init so it comes after
     deferred probe has iterated making startup smoother.
   - fixes to reference counting of the DT nodes for constraints from
     Charles Keepax.  This has little practical impact since all real
     users of the regulator bindings use FDT which doesn't need the
     reference counting.
   - lots of cleanups, especially to the Samsung drivers.
   - support for Linear Technologies LTC3589, Texas Instruments
     TPS658640 and X-Powers AXP20x"
