[PATCH v3 2/3] dt-bindings: mfd: mediatek: mt6397: Convert to DT schema format
From: Macpaul Lin
Date: Fri Sep 13 2024 - 14:00:02 EST
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:
- Convert sound/mt6358.txt and merge into parent MT6397 PMIC DT schema.
- Align to generic name "audio-codec" for codec and sound subdevices.
- Add "mediatek,dmic-mode" and "Avdd-supply" properties.
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".
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.

Changes for v1:
- This patch depends on conversion of mediatek,mt6397-regulator.yaml
[1] https://lore.kernel.org/lkml/20240807091738.18387-1-macpaul.lin@xxxxxxxxxxxx/T/
Changes for v2:
- This patch has been made base on linux-next/master git repo.
- Keep the parent and child relationship with mediatek,pwrap in description.
[2] https://lore.kernel.org/all/20240826-slurp-earphone-0d5173923ae8@spud/
- Keep the $ref for regulators since dt_binding_check didn't report any issue
based on linux-next/master repo.
- Fix description of mt6397/mt6323 devices, use "power management chip"
instead of "multifunction device"
- Drop unnecessary comments or description according to the review.
- Convert sub-modules to DT Schema:
- RTC, LEDs, power-controllers, regulators
- Drop duplicate sub node name and description for sub-modules
- RTC, Keys
- examples:
- drop parent pwrap node
- Add examples from mediatek,mt6323-regulator.yaml
- Add examples from mediatek,mt6358-regulator.yaml
- Add examples from mediatek,mt6397-regulator.yaml
- Complete the examples as could as possible.
Changes for v3:
- Rebased on linux-next/master git repo near next-20240906.
- Revise commit message.
- Regulators:
- Use "additionalProperties: true" and add "contains" for matching
$ref DT bindings.
- Simplify regulator name labels in device tree examples.
- LEDs:
- Use LED bindings.
- Squash following patches in v2 for removing old text format DT bindings
into this patch, includes:
- leds-mt6323.txt, mt6323-poweroff.txt, rtc-mt6397.txt, sound/mt6358.txt.
- Fix file format of DT schemas, add blank between properties.
- Fix 'make checkrefdoc' errors, update reference in mediatek,pmic-keys.yaml.
