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.

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.

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.

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.

Add support for the 3.3V booster regulator embedded in stm32h7 and stm32mp1
devices, that can be used to supply ADC analog input switches.
This regulator is supplied by vdda. It's controlled by using SYSCFG:
- STM32H7 has a unique register to set/clear the booster enable bit
- STM32MP1 has separate set and clear registers to configure it.

Add support for the rk809 and rk817 regulator driver.
Their specifications are as follows：
1. The RK809 and RK809 consist of 5 DCDCs, 9 LDOs
and have the same registers for these components except dcdc5.
2. The dcdc5 is a boost dcdc for RK817 and is a buck for RK809.
3. The RK817 has one switch but The Rk809 has two.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board.
The Lochnagar board provides power supplies for the attached
CODEC/Amp device. Currently this driver supports the microphone
supplies and the digital core voltage for the attached
device. There are some additional supplies that will be
added in time but these supplies are sufficient for most
systems/use-cases.

Add the QCOM RPMh regulator driver to manage PMIC regulators
which are controlled via RPMh on some Qualcomm Technologies, Inc.
SoCs. RPMh is a hardware block which contains several
accelerators which are used to manage various hardware resources
that are shared between the processors of the SoC. The final
hardware state of a regulator is determined within RPMh by
performing max aggregation of the requests made by all of the
processors.
Add support for PMIC regulator control via the voltage regulator
manager (VRM) and oscillator buffer (XOB) RPMh accelerators.
VRM supports manipulation of enable state, voltage, and mode.
XOB supports manipulation of enable state.

MFD part for bd71837 was changed during the review. Clean regulator part to
match changed MFD:
- renamed header file => fix include
- remove unused platdata as also type definition was removed
- Kconfig option for MFD part was changed => fix depends on clause
- Rename Kconfig option for regulators
As Kconfig option for regulators gets now used (when dependency to MFD is
satisfied) change it so that it won't require new change when support for
bd71847 is added.
