regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error
The kernel test robot reported the following 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.

21b72156ed regulator: bd718x7: Split driver to common and bd718x7 specific parts
Few ROHM PMICs allow setting the voltage states for different system states
like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific
mechanisms. bd718x7 driver implemented device-tree parsing functions for
these state specific voltages. The parsing functions can be re-used by
other ROHM chip drivers like bd71828. Split the generic functions from
bd718x7-regulator.c to rohm-regulator.c and export them for other modules
to use.

regulator: bd71828: Basic support for ROHM bd71828 PMIC regulators
ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. Bucks
1,2,6 and 7 can be assigned to a regulator group controlled by run-levels.
Eg. Voltages and enable/disable statuses for specific run-levels (run0 to
run3) can be set via register interface and run level changes can then be
done either via I2C or GPIO.

This initial commit does not support assigning bucks to be controlled via
run-levels but only allows them to be individually controlled.

LDO5 voltage can also be controlled by GPIO2 pin and register interfaces
but this driver only supports the control via register.
