The RTC on mpfs and pic64gx has a reset pin, but until now this has been
undocumented because platform firmware takes the RTC out of reset on
first-party boards (or those using modified versions of the vendor
firmware), but not all boards may take this approach. Permit providing a
reset in devicetree for Linux, or other devicetree-consuming software,
to use.

The `interrupts` property indicates an RTC alarm interrupt, which is
required for RTCs that support the alarm feature, which is not supported
by the Loongson-1C RTC. We exclude it for a more accurate description.
Changing the `allowed` property is ABI-breaking behavior, but
throughout the existing Loongson DTS{i}, the description of the RTC
nodes conforms to the modified bingding rules.
Thus, the existing Loongson DTS{i} will not be affected.

The Renesas RZ/V2H RTC IP is based on the same RTCA3 IP as RZ/G3S
(r9a08g045), with the following differences:
- It lacks the time capture functionality
- The maximum supported periodic interrupt frequency is 128Hz instead
of 256Hz
- It requires two reset lines instead of one
Add new compatible string "renesas,r9a09g057-rtca3" for RZ/V2H and update
the binding accordingly:
- Allow "resets" to contain one or two entries depending on the SoC.
- Add "reset-names" property, but make it required only for RZ/V2H.

- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M

- Tegra264 is a new chip from NVIDIA, but support is fairly minimal

- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95.
- Two newly added ASPEED BMC based motherboards, and one that got

- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm.

RTC tracks clock time during system suspend and it is used as a wakeup
source on S32G2/S32G3 architecture.
RTC from S32G2/S32G3 is not battery-powered and it is not kept alive
during system reset.

On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which a
driver can take into account.
On platforms where the offset is stored in a Qualcomm specific UEFI
variable the variables are also accessed in a non-standard way, which
means that the OS cannot assume that the variable service is available
by the time the RTC driver probes.
Add a 'qcom,uefi-rtc-info' boolean flag to indicate that the RTC offset
is stored in a Qualcomm specific UEFI variable so that the OS can
determine whether to wait for it to become available.
The UEFI variable is
882f8c2b-9646-435f-8de5-f208ff80c1bd-RTCInfo
and holds a 12-byte structure where the first four bytes is a GPS time
offset in little-endian byte order.

PCF2127 is an SPI device, thus its binding should reference
spi-peripheral-props.yaml.
Add a reference to spi-peripheral-props.yaml to fix the following
dt-schema warning:
imx7d-flex-concentrator.dtb: rtc@0: 'spi-max-frequency' does not match any of the regexes: 'pinctrl-[0-9]+'

Qualcomm x1e80100 firmware sets the ownership of the RTC alarm to ADSP.
Thus writing to RTC alarm registers and receiving alarm interrupts is not
possible.
Add a qcom,no-alarm flag to support RTC on this platform.

Convert the Spreadtrum SC27xx PMIC bindings to DT schema. Adjust the
filename to match the compatible of the only in-tree user, SC2731.
Change #interrupt-cells value to 1, as according to [1] that is the
correct value.
Move partial examples of child nodes in the child node schemas to this new
MFD schema to have one complete example.

Document the RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC.
The RTC IP available on Renesas RZ/V2H is almost identical with the
one found on Renesas RZ/G3S (it misses the time capture functionality
which is not yet implemented on proposed driver). For this, added also a
generic compatible that will be used at the moment as fallback for both
RZ/G3S and RZ/V2H.

Convert the mfd: mediatek: mt6397 binding to DT schema format.
MT6323, MT6358, and MT6397 are PMIC devices with multiple function
subdevices. They share a common PMIC design but have variations in
subdevice combinations.
Key updates in this conversion:
1. RTC:
- Convert rtc-mt6397.txt and merge into parent MT6397 PMIC DT schema.
2. Regulators:
- Align to generic name "regulators".
- Update references from .txt to .yaml for mt6323, mt6358, and mt6397
regulators.
- Simplify regulator name labels in device tree examples.
3. Audio Codec:
- Simplify Audio Codec part with updating compatible items.
- Align to generic name "audio-codec" for codec and sound subdevices.
4. Clocks:
- Align to generic name "clocks" for clockbuffer subdevices.
5. LEDs:
- Convert leds-mt6323.txt and merge into parent MT6397 PMIC DT schema.
- Update LED binding.
6. Keys:
- Add detailed descriptions for power and home keys.
- Add compatible: mediatek,mt6358-keys.
7. Power Controller:
- Convert mt6323-poweroff.txt and merge into parent MT6397 PMIC DT
schema.
- Add #power-domain-cells property to fix dt-binding check error.
- Clarify "BBPU" as "Baseband power up".
8. Pinctrl:
- Align to generic name "pinctrl" instead of "pin-controller".
9. Compatible:
- Drop "mediatek,mt6357" since there is a separated DT Schema
for PMIC MT6357.
10. Examples:
- MT6323: Retain complete examples for this PMIC.
- MT6358 and MT6397: simplify settings in regulators.
- Preserve "audio-codec", "clocks", "pinctrl", "rtc", and "keys"
sections as they contain typical settings for different PMICs.
Additional updates:
- MAINTAINERS: Add co-maintainers and reference to
mfd/mediatek,mt6397.yaml for LED and power-controller drivers.
- input/mediatek,pmic-keys.yaml: Update reference to
mfd/mediatek,mt6397.yaml.
