Pull regulator updates from Mark Brown:
 "This time around most of the changes are a lot of new drivers along
  with the standard set of fixes and cleanups (thanks again largely to
  Axel Lin).  We do have one nice new feature in the core which factors
  out the disappointingly tricky code around DT parsing, only a couple
  of drivers have been converted so far:

   - Factor out the code for parsing the standard bindings for a set of
     regulators out of DT, making the probe part of a lot of drivers
     simplier.
   - New drivers for Dialog DA9213, HiSilicon HI6420, Intersil
     ISL9305/H, Ricoh RN5T618, Rockchip RK808, Skyworks SKY81452,
     Silergy SYR82x, and Qualcomm RPM"
