Hi,
This patch series adds MFD, PMIC keys, and regulator support for MT6357.
MT6357 is a MediaTek PMIC very similar to MT6358.

Currently, MTK bindings related to the PMICs are not converted yet (still .txt):

soc/mediatek/pwrap.txt (all PMIC parent)
      |
      V
mfd/mt6397.txt (support lot of mt63XX PMIC)
      +---------------+----------------+---...
      V               V                V
regulator/...      rtc/...          codec/...

1) Convert pwrap to yaml is ok.

2) For the PMIC bindings, there are two option:
- Convert mt6397.txt to mediatek,mt6397.yaml and continue to support multiple
  PMIC with only one file. IMO, the file will be hard to read because
  the supported features aren't the same for each PMIC.

- Make a binding file for each PMIC ref:
    - mfd/mediatek,mt6357.yaml
    - mfd/mediatek,mt6358.yaml
    - ...

3) All PMIC daughter bindings (regulator, rtc, codec, led, ...) aren't fully
converted yet. Refering to the two PMIC convertion options above:
- To be clean, all daughter bindings should be converted. This is hard because
  a good understanding of each device is requiered to write efficient bindings.
- Only daughter bindings supported by the added PMIC should be converted, that
  allows to do the task conversion step by step.

In the V4 of this serie, I chose the second option.

Regards,
Alex

Changes in v7:
- Drop mt6397 RTC schema conversion.
- Integrate mt6357 RTC schema directly in mediatek,mt6357.yaml.
- Fix unit address in mediatek,pwrap.yaml.
- Link to v6: https://lore.kernel.org/r/20221005-mt6357-support-v6-0-4f589756befa@baylibre.com

Changes in v6:
- Fix typo in documentations.
- Remove mediatek,mt6397-rtc.yaml example.
- Align pwrap convertion with the original .txt file.
- Remove unecessary include in the mt6357-regulator driver.
- Link to v5: https://lore.kernel.org/r/20221005-mt6357-support-v5-0-8210d955dd3d@baylibre.com

Changes in v5:
- Add missing maintainers
- Improve RTC binding by adding rtc.yaml ref and start-year property
- Split the txt->yaml conversion in one commit and the addition of the
  new mt6357-rtc compatible in another commit.
- Improve PWRAP binding:
  - clocks and clock-name have been refactored.
  - reset-names is now properly dependent to resets.
  - additionalProperties change from true to false.
  - change example for a most recent and popular SoC.
  - "allOf" part has been simplified.
- Pass binding tests with the updated tools. Here the command:
  "make DT_CHECKER_FLAGS=-m dt_binding_check"
- Link to v4: https://lore.kernel.org/r/20221005-mt6357-support-v4-0-5d2bb58e6087@baylibre.com

Changes in v4:
- "dt-bindings: mfd: mt6397: add binding for MT6357" has been applied
  by Lee Jones
- All fixed regulator are now refering to fixed-regulator.yaml
- vfe28 and vcamio18 regulators have been added
- pwrap binding has been converted and mt8365 support has been added
- mt6357 PMIC binding has been created
- mt6397 RTC binding has been converted and mt6357 support has been added
- Link to v3: https://lore.kernel.org/r/20221005-mt6357-support-v3-0-7e0bd7c315b2@baylibre.com

Changes in v3:
- To be consistent with regulator/driver.h and helper.c, shift
  variables have been removed and the mask values have been directly shifted.
- Remove index tables and rework volt tables to use set/get helper functions.
- Add comment to structure and function.
- Fix Fabien Parent mail address.
- Link to v2: https://lore.kernel.org/r/20221005-mt6357-support-v2-0-f17ba2d2d0a9@baylibre.com

Changes in v2:
- Rebase
- Fix typo
- Remove dependencies with https://lore.kernel.org/all/20220415153629.1817202-1-fparent@baylibre.com/
  which is no longer relevant.

- Convert soc/mediatek/pwrap.txt to soc/mediatek/mediatek,pwrap.yaml
- Add syscon compatible const for mt8186 and mt8195 to match the DTS needs,
  which is missing from pwrap.txt.

Currently, almost all MT63XX PMIC are documented mfd/mt6397.txt.
Unfortunately, the PMICs haven't always similar HW sub-features.
To have a better human readable schema, I chose to make one PMIC schema
to match the exact HW capabilities instead of convert mt6397.txt to
mediatek,mt63xx.yaml and put a bunch of properties behind
"if contain ... then ..."

- add interrupt property
- change property refs to match with new yaml documentation

+description: |
+  MT6357 is a power management system chip containing 5 buck
+  converters and 29 LDOs. Supported features are audio codec,
+  USB battery charging, fuel gauge, RTC
+
+  This is a multifunction device with the following sub modules:
+  - Regulator
+  - RTC
+  - Keys
+
+  It is interfaced to host controller using SPI interface by a proprietary hardware
+  called PMIC wrapper or pwrap. This MFD is a child device of pwrap.
+  See the following for pwrap node definitions:
+  Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml

- Change the node name from "mt6358" to "pmic", "mt6358rtc" to "rtc" and
"mt6358keys" to "keys" to be consistent with the generic names recommendation.

[2/8] regulator: dt-bindings: Add binding schema for mt6357 regulators
      commit: b4387db19d7f1caf166852782a5f0e5a393bdf24
[7/8] regulator: add mt6357 regulator
      commit: dafc7cde23dca239987d3cd000b11cdccc3728ea

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

The regulator driver (and bindings) were merged by Mark.  Could you take
the rest of this series via your mediatek tree?  The input driver (and
bindings) are ack'd by Dmitry.

Yes I can do that but 3/8 does not apply cleanly. Could you please rebase on top 
of v6.2-tmp/soc?

Thanks

Hi Matthias,

I've pushed the V8 rebased on top of v6.2-tmp/soc.
https://lore.kernel.org/r/20221005-mt6357-support-v8-0-560caaafee53@baylibre.com

Thanks,

Gentle ping to merge the v8 rebased on top of v6.2-tmp/soc.
