Pull regulator updates from Mark Brown:
 "A couple of new features in the core, the most interesting one being
  support for complex regulator coupling configurations initially
  targeted at nVidia Tegra SoCs, and some new drivers but otherwise
  quite a quiet release.

  Summary:

   - Core support for gradual ramping of voltages for devices that can't
     manage large changes in hardware from Bartosz Golaszewski.

   - Core support for systems that have complex coupling requirements
     best described via code, contributed by Dmitry Osipenko.

   - New drivers for Dialog SLG51000, Qualcomm PM8005 and ST
     Microelectronics STM32-Booster"
