The S2MPS15 PMIC is similar in functionality to S2MPS11/14 PMIC. It contains
27 LDO and 10 Buck regulators and allows programming these regulators via a
I2C interface. This patch adds initial support for LDO/Buck regulators of
S2MPS15 PMIC.

Add support for TPS65086 PMIC regulators.
The regulators set consists of 3 Step-down Controllers, 3 Step-down
Converters, 3 LDOs, 3 Load Switches, and a Sink and Source LDO. The
output voltages are configurable and are meant to supply power to a
SoC and/or other components.

The driver depends on MFD_STW481X but there isn't a build dependency so
it's a good idea to allow the driver to always be built when the
COMPILE_TEST option is enabled.
That way, the driver can be built with a config generated by make
allyesconfig and check if a patch would break the build.

Add regulator support for mt6311.
It has 2 regulaotrs - Buck and LDO, provide the related buck/ldo voltage

The charger and safeout parts of MAX77843 are almost the same as MAX77693.
From regulator point of view the only differences are the constraints
and register values related to these constraints. Now the max77693

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Pull regulator updates from Mark Brown:
"The main thing this time around is support for suspend mode
configuration from DT which will enable some very useful power savings
on systems where we can't rely on the bootloader configuration. We
still don't really support dynamic configuration of this at runtime,
that may come later if there is any demand.
Summary:
- Support for specifying the target regulation mode and voltage
during system suspend via DT, enabling power savings in that mode.
- Reduce the default verbosity of the logging on boot, improving boot
times especially for systems with very large numbers of regulators.
- Lots of cleanups and fixes for Maxim PMIC drivers.
- New driver for Richtek RT5033"

Add driver support for HiSilicon Hi6421 voltage regulators.
Two rules for regulator enabling are defined in hi6421 spec:
1) Between disable and enable of each regulator (LDOs or BUCKs), there must
be a protection gap. Use @off_on_delay of regulator core to implement this.
2) No two regulators can be enabled at the same time. Use mutex in
hi6421_regulator_pdata to ensure this. A protection gap of 100us is added
into each LDO/BUCK's .enable_time.

Pull regulator updates from Mark Brown:
"The bulk of the changes for this release are a few new drivers however
there are a couple of noticable core changes and the usual stream of
cleanups and fixes:
- move disable of unused regulators later in init so it comes after
deferred probe has iterated making startup smoother.
- fixes to reference counting of the DT nodes for constraints from
Charles Keepax. This has little practical impact since all real
users of the regulator bindings use FDT which doesn't need the
reference counting.
- lots of cleanups, especially to the Samsung drivers.
- support for Linear Technologies LTC3589, Texas Instruments
TPS658640 and X-Powers AXP20x"
