Introduces a new devicetree property to specifies the time window (in
milliseconds) following a critical under-voltage (UV) event during which
less critical actions can be safely carried out by the system.
Less Critical Actions:
- Logging the under-voltage event for later analysis.
- Saving less critical data that may be useful for diagnosing issues or
for audit purposes.
More Critical Actions (post the less critical window):
- Initiating procedures to properly shutdown hardware to prevent damage.
The 'regulator-uv-less-critical-window-ms' property is crucial for
conveying board-specific hardware characteristics, not for enforcing a
certain policy. The time window represented by this property is derived
from the physical attributes of the hardware like the capacity of
on-board capacitors, the power consumption of the components, and the
time needed to safely shut down hardware to prevent damage. These
attributes can significantly vary between different boards, making it a
board-specific property rather than a policy directive.
By providing a precise representation of the time available for less
critical actions post an under-voltage event, this property enables the
kernel to make informed decisions on action prioritization, ensuring
that essential preventative measures are taken to avoid hardware damage
while also allowing for data capture and analysis.

In certain projects, the main system regulator, composed of simple
components including an under-voltage detector and capacitors, can be
aptly described as a fixed regulator in the device tree. To cater to
such use cases, this patch extends the fixed regulator binding to
support the 'system-critical-regulator' property. This property
signifies that the fixed-regulator is vital for system stability.

The MediaTek MT6366 PMIC is similar to the MT6358 PMIC. It is designed
to be paired with the MediaTek MT8186 SoC. It has 9 buck regulators and
29 LDO regulators, not counting ones that feed internally and basically
have no controls. The regulators are named after their intended usage
for the SoC and system design, thus not named generically as ldoX or
dcdcX, but as vcn33 or vgpu.
The differences compared to the MT6358 are minimal:
- Regulators removed: VCAMA1, VCAMA2, VCAMD, VCAMIO, VLDO28
- Regulators added: VM18, VMDDR, VSRAM_CORE
Both PMIC models contain a chip ID register at the same address that
can be used to differentiate the actual model. Thus, even though the
MT6366 is not fully backward compatible with the MT6358, it still falls
back on the MT6358 compatible string. It is up to the implementation
to use the chip ID register as a probing mechanism.
Update the MT6358 regulator binding and add entries for all the MT6366's
regulators and their supplies. The regulator node names follow a cleaned
up style without type prefixes and with underscores replaced with hyphens.

The MT6358 PMIC allows changing operating modes for the buck regulators,
but not the LDOs. Existing device trees and the Linux implementation
already utilize this through the standard regulator-allowed-modes
property.
The values currently used in existing device trees are simply raw
numbers. The values in the Linux driver are matching numbers defined
with macros denoting the two supported modes. Turns out these two
modes are common across parts of the larger MT63xx PMIC family. The
MT6397 regulator binding already has macros for the two modes, with
matching numbers.
Codify the supported values for regulator-allowed-modes for the MT6358
in the device tree binding: 0 and 1 are supported for buck regulators,
and the property should not be present for LDO regulators. Users should
use the dt-bindings/regulator/mediatek,mt6397-regulator.h header for
the macros, instead of using raw numbers.

Convert this from the old style text based binding to the new DT schema
style. This will make adding the MT6366 portion easier.
The examples have been trimmed down considerably, and the remaining
entries now match what is seen in actual device trees, minus some
properties that aren't covered by the bindings yet, or don't make
sense on their own.
The original submitter seems to have left MediaTek, so instead the
submitter and maintainer for the MT6366 binding is listed as the
maintainer here.

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.
Document Renesas RAA215300 PMIC bindings.
The RAA215300 is a high Performance 9-Channel PMIC supporting DDR
Memory, with Built-In Charger and RTC.
It supports DDR3, DDR3L, DDR4, and LPDDR4 memory power requirements.
The internally compensated regulators, built-in Real-Time Clock (RTC),
32kHz crystal oscillator, and coin cell battery charger provide a
highly integrated, small footprint power solution ideal for
System-On-Module (SOM) applications. A spread spectrum feature
provides an ease-of-use solution for noise-sensitive audio or RF
applications.

Merge series from Chen-Yu Tsai <wenst@chromium.org>:
This series is a cleanup and improvement of the MT6358 regulator driver.
Various discrepancies were found while preparing to upstream MT8186
device trees, which utilize the MT6366 PMIC, that is also covered by
this driver.
Patches 1~8 should go through the regulator tree, and patch 9 through
the soc tree.
This series can be seen as two parts:
Part 1 - Fixing bogus regulators (patches 1~4 and 9)
There are some regulators listed in the bindings and driver that have no
corresponding pin on the actual hardware. MediaTek says these are a
hardware construct for shared control of the same regulator in the
VCN33 case and an alternative control scheme for low power suspend.
In the VCN33 case, there's only one actual regulator, so we merge the
two and rename them to match the hardware pin. No existing devices use
these AFAICT, so this should be safe to change.
In the *_SSHUB case, the two extra regulators refer to alternative
configuration registers of the same regulators. They are intended for
the SoC's low power mode companion processor to use, not the main
processor or OS. It should be left to the implementation to choose
which set of registers to actually control.
Part 2 - Code cleanup (patches 5 and 6)
Various tables in the regulator driver were not constant, even though
they are just lookup tables. With some reworking of the code, they are
made constant.
Also, some regulators that have a single linear range were using linear
range helpers. This is more complicated than just declaring the range
and step directly in the description. This is simplified to use the
latter approach.
Please have a look. After this series is done I'll send out patches for
the MT6366 PMIC, which is what started this. That will also include
updated YAML bindings for MT6366. I think we can merge MT6358 bindings
into them afterwards.
[1] https://lore.kernel.org/linux-arm-kernel/20230609075032.2804554-1-wenst@chromium.org/
The *_sshub regulators are actually alternate configuration interfaces
for their non *_sshub counterparts. They are not separate regulator
outputs. These registers are intended for the companion processor to
use to configure the power rails while the main processor is sleeping.
They are not intended for the main operating system to use.
Since they are not real outputs they shouldn't be modeled separately.
Remove them. Luckily no device tree actually uses them.

The ldo_vcn33_bt and ldo_vcn33_wifi regulators are actually the same
regulator, having the same voltage setting and output pin. There are
simply two enable bits that are ORed together to enable the regulator.
Having two regulators representing the same output pin is misleading
from a design matching standpoint, and also error-prone in driver
implementations.
Merge the two as ldo_vcn33. Neither vcn33 regulators are referenced
in upstream device trees. As far as hardware designs go, none of the
Chromebooks using MT8183 w/ MT6358 use this output.
