Subject: [PATCH v6 00/10] Add MediaTek MT6357 PMIC support
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 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.
