regulator: Add MAX20086-MAX20089 driver
The MAX20086-MAX20089 are dual/quad power protectors for cameras. Add a
driver that supports controlling the outputs individually. Additional
features, such as overcurrent detection, may be added later if needed.

regulator: Introduce tps68470-regulator driver
The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in
the kernel the Regulators and Clocks are controlled by an OpRegion
driver designed to work with power control methods defined in ACPI, but
some platforms lack those methods, meaning drivers need to be able to
consume the resources of these chips through the usual frameworks.

This commit adds a driver for the regulators provided by the tps68470,
and is designed to bind to the platform_device registered by the
intel_skl_int3472 module.

This is based on this out of tree driver written by Intel:
https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/regulator/tps68470-regulator.c
with various cleanups added.

1aad39001e regulator: Support ROHM BD71815 regulators
Support voltage control for regulators on ROHM BD71815 PMIC.

ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.

LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.

This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.

regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error

All errors (new ones prefixed by >>):

   xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel':
   qcom-rpmh-regulator.c:(.text+0x270): undefined reference to `rpmh_write'

   qcom-rpmh-regulator.c:(.text+0x2fc): undefined reference to `rpmh_write_async'

Which is due to REGULATOR_QCOM_RPMH depending on
QCOM_RPMH || COMPILE_TEST. The problem is that QOM_RPMH can now
be a module, which in that case requires REGULATOR_QCOM_RPMH=m
to build.

However, if COMPILE_TEST is enabled, REGULATOR_QCOM_RPMH can be
set to =y while QCOM_RPMH=m which will cause build failures.

The fix here is to add (QCOM_RPMH=n && COMPILE_TEST) to the
dependency.

Feedback would be appreciated!

Merge series "Support ROHM BD9576MUF and BD9573MUF PMICs" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
Initial support for ROHM BD9576MUF and BD9573MUF PMICs.

These PMICs are primarily intended to be used to power the R-Car family
processors. BD9576MUF includes some additional safety features the
BD9573MUF does not have. This initial version of drivers does not
utilize these features and for now the SW behaviour is identical.

Please note that this version of drivers is only tested on BD9576MUF
but according to the data-sheets the relevant parts of registers should
be same so drivers should also work on BD9573MUF.

This patch series includes MFD, watchdog and regulator drivers with
basic functionality such as:

- Enabling and pinging the watchdog
- configuring watchog timeout / window from device-tree
- reading regulator states/voltages
- enabling/disabling VOUT1 (VD50) when control mode B is used.

This patch series does not bring interrupt support. BD9576MUF and BD9573MUF
are designed to keep the IRQ line low for whole duration of error
condition. IRQ can't be 'acked'. So proper IRQ support would require
some IRQ limiter implementation (delayed unmask?) in order to not hog
the CPU.
