There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now.
- exynos2200 is a recent high-end mobile phone chip used in a
few Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it.
There are five more chips in a separate branch, as those are new
chip families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly
added machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and
Sophgo sg2042.
- 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
removed
- 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.
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5.

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.

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.

STM32 RTC is capable to handle 3 specific pins of the soc (out1, out2,
out2_rmp) and to outputs 2 signals (LSCO, alarm-a).
This feature is configured thanks to pinmux nodes and pinctrl framework.
This feature is available with compatible st,stm32mp1-rtc and
st,stm32mp25-rtc only.

Add support for Versal and Versal NET SoCs. Both of them should use the
same IP core but differences can be in integration part that's why create
separate compatible strings.
Also describe optional power-domains property. It is optional because power
domain doesn't need to be onwed by non secure firmware hence no access to
control it via any driver.
