The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

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.

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!

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.

This regulator/backlight driver handles the ATTINY88 present on the
RPi 7" touchscreen panel and exposes the power/backlight interfaces.

Adds support for the RT4801 DSV. It has two regulators (DSVP/DSVN) with
an I2C interface. DSVP/DSVN can provide the display panel module for the
positive/negative voltage range from (+/-)4V to (+/-)6V.

Qualcomm platforms have LAB(LCD AMOLED Boost)/IBB(Inverting Buck Boost)
regulators, labibb for short, which are used as power supply for
LCD Mode displays.
This patch adds labibb regulator driver for pmi8998 PMIC, found on
SDM845 platforms.
[sumits: reworked the driver design as per upstream review]

This patch adds support for ON Semiconductor FAN53880 regulator.
The FAN53880 is an I2C porgrammable power management IC (PMIC)
that contains a BUCK (step-down converter), four LDOs (low dropouts)
and one BOOST (step-up converter). It is designed for mobile power
applications.

Some Qualcomm PMICs have the capability to source the VBUS output to
connected peripherals. This driver will register a regulator to the
regulator list to enable or disable this source by an external driver.

Add driver for cros-ec-regulator, representing a voltage regulator that
is connected and controlled by ChromeOS EC, and is controlled by kernel
with EC host commands.

Series extracts a "linear ranges" helper out of the regulator
framework. Linear ranges helper is intended to help converting
real-world values to register values when conversion is linear. I
suspect this is useful also for power subsystem and possibly for clk.

Change the regulator helpers to use common linear_ranges code.
