Merge tag 'regulator-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Browse Source 
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"

* regulators in a system). Callback shall be implemented.
* @detach_regulator: Callback invoked on destruction of a coupled regulator.
* This callback is optional and could be NULL.
* @balance_voltage: Callback invoked when voltage of a coupled regulator is
* changing. Called with all of the coupled rdev's being held
* under "consumer lock". The callee should perform voltage
* balancing, changing voltage of the coupled regulators as
* needed. It's up to the coupler to verify the voltage
* before changing it in hardware, i.e. coupler should
* check consumer's min/max and etc. This callback is
* optional and could be NULL, in which case a generic
* voltage balancer will be used.
