Merge tag 'regulator-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"The biggest changes in the core this time around have been some
refactorings that move us towards being able to drop the list of
regulators maintained by the core and instead just use the driver
model list maintained for the class devices for regulators which will
make the code smaller and avoid some potential bugs.
Otherwise another fairly quiet release for the regulator API,
highlights include:
- a new API for setting voltages based on a minimum, target, maximum
triplet
- support for continuous voltage ranges rather than tables of
explicit steps in the PWM regulator, requiring less explicit
configuration
- new driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
and Qualcomm RPM"
