regulator: sm5703: Remove because it is unused and fails to build
This file does not compile because <linux/mfd/sm5703.h> is missing.
In KConfig, it depends on MFD_SM5703.

Both MFD_SM5703 and the missing include rely on another patch that never
got merged. The last iteration related to this patch is [1].

So remove this dead-code and undo commit e8858ba89c ("regulator:
sm5703-regulator: Add regulators support for SM5703 MFD")

a9b7ce28fd regulator: bd96801: ROHM BD96801 PMIC regulators
The ROHM BD96801 "Scalable PMIC" is an automotive grade PMIC which can
scale to different applications by allowing chaining of PMICs. The PMIC
also supports various protection features which can be configured either
to fire IRQs - or to shut down power outputs when failure is detected.

The driver implements basic voltage control and sending error
notifications.

NOTE:
The driver does not support doing configuration which require the PMIC
to be in STBY state. The omitted feature set includes setting safety
limit values, changing LDO voltages and controlling enable state for
some regulators.
Also, the ERRB IRQ is not handled.

regulator: Add Renesas RZ/G2L USB VBUS regulator driver
As per the RZ/G2L HW manual, VBUSEN can be controlled by the VBOUT
bit of the VBUS Control Register. This register is mapped in the reset
framework. The reset driver expose this register as regmap and instantiates
this driver. The consumer will use the regulator API to control the VBOUT
bit as the control need to be done in the atomic context.

11d861d227 regulator: add pm8008 pmic regulator driver
The Qualcomm PM8008 is an I2C-controlled PMIC containing seven LDO
regulators.

The driver is based on a driver submitted by Satya Priya, but it has
been cleaned up and reworked to match the new devicetree binding which
no longer describes each regulator as a separate device.

This avoids describing internal details like register offsets in the
devicetree and allows for extending the implementation with features
like over-current protection without having to update the binding.

Specifically note that the regulator interrupts are shared between all
regulators.

Note that the secondary regmap is looked up by name and that if the
driver ever needs to be generalised to support regulators provided by
the primary regmap (I2C address) such information could be added to the
device-id table.

This also fixes the original implementation, which looked up regulators
by 'regulator-name' property rather than devicetree node name and which
prevented the regulators from being named to match board schematics.

similar and can share a driver, but only the system LDOs have a DT

The system LDOs have a single linear range. The voltage step is not an
integer, so a custom .list_voltage is needed to get the rounding right.

2947a4567f treewide: update LLVM Bugzilla links
LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues.  While all of the links are still valid, they may not necessarily
show the most up to date information around the issues, as all updates
will occur on GitHub, not Bugzilla.

Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number.  Thankfully, LLVM maintains this mapping
through two shortlinks:

  https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
  https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>

Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up to
date information.  Each migrated issue links back to the Bugzilla entry,
so there should be no loss of fidelity of information here.

Add Richtek RTQ2208 SubPMIC support
Merge series from Alina Yu <alina_yu@richtek.com>:

This patch series adds support for RTQ2208 SubPMIC regulators.
The RTQ2208 is a multi-phase, programmable power management IC that
integrate with dual multi-configurable, synchronous buck converters
and two ldos. The bucks features wide output voltage range from 0.4V to 2.05V
and the capability to configure the corresponding power stages.

Merge series from Biju Das <biju.das.jz@bp.renesas.com>:

This patch series aims to add support for Renesas PMIC RAA215300 and
built-in RTC found on this PMIC device.

The details of PMIC can be found here[1].

Renesas PMIC RAA215300 exposes two separate i2c devices, one for the main
device and another for rtc device.

regulator: Add Renesas PMIC RAA215300 driver
The RAA215300 is a 9-channel PMIC that consists of
 * Internally compensated regulators
 * built-in Real Time Clock (RTC)
 * 32kHz crystal oscillator
 * coin cell battery charger

The RTC on RAA215300 is similar to the IP found in the ISL1208.
The existing driver for the ISL1208 works for this PMIC too,
however the RAA215300 exposes two devices via I2C, one for the RTC
IP, and one for everything else. The RTC IP has to be enabled
by the other I2C device, therefore this driver is necessary to get
the RTC to work.

The external oscillator bit is inverted on PMIC version 0x11.

Add PMIC RAA215300 driver for enabling RTC block and instantiating
RTC device based on PMIC version.

mfd/pinctrl/regulator: Add RK806 Support
Merge series from Sebastian Reichel <sebastian.reichel@collabora.com>:

All existing boards using RK3588/RK3588s use RK806 PMICs. This series is now
the main blocker for full upstream support of those boards and it would be good
to have it merged for 6.5 :) The patches have been tested on multiple different
platforms and are mainly missing an Ack from Mark or Liam for the rk808-regulator
changes.

Merging must happen through a single tree, since the pinctrl and regulator
drivers rely on the register definitions from the include file added by the MFD
patch. My suggested merge strategy is that Lee creates an immutable branch for
the regulator/pinctrl tree once all Acks have been collected.

c4b02c92d9
regulator: Drop obsolete dependencies on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop several occurrences of
of_match_ptr(), __maybe_unused and some ifdef guarding, as we now know
what all of this will resolve to, we might as well save cpp some work.

5e88619b30 mfd: silergy,sy7636a: Add config option MFD_SY7636A
Add a specific MFD_SY7636A config option.

As part of this change we can use MFD_SY7636A as a dependency for all
SY7636a components and also remove the name from MFD_SIMPLE_MFD_I2C as
it no longer needs to be selectable.

MediaTek Helio X10 MT6795 - MT6331/6332 Regulators
Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series adds support for the regulators found in MT6331 and MT6332
main/companion PMICs.

Adding support to each driver in each subsystem is done in different
patch series as to avoid spamming uninteresting patches to maintainers.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

regulator: drivers: Add TI TPS65219 PMIC regulators support
The regulators set consists of 3 bucks DCDCs and 4 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.

Validation:
Visual check: cat /sys/kernel/debug/regulator/regulator_summary
Validation: userspace-consumer and virtual-regulator required
to test further

Enable/Disable:
