Merge tag 'regulator-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"The bulk of the standout changes in this release are cleanups, with
the core work being a combination of factoring out common code into
helpers and the completion of the conversion of the core to use GPIO
descriptors.
Summary:
- Addition of helper functions for current limits and conversion of
drivers to use them by Axel Lin.
- Lots and lots of cleanups from Axel Lin.
- Conversion of the core to use GPIO descriptors rather than numbers
by Linus Walleij.
- New drivers for Maxim MAX77650 and ROHM BD70528"
