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. - Add a new 'mt6359-regulator' to the compatibles of regulators. Merge from the other patch [1]. 3. ADC: - Add a new 'adc' property and include a $ref for sub-device node of MT6359 PMIC AUXADC: 'mediatek,mt6359-auxadc'. Merge from the other patch [1]. 4. Audio Codec: - Simplify Audio Codec part with updating compatible items. - Add 'mt6359-codec' to the compatible. 5. Clocks: - Align to generic name "clocks" for clockbuffer subdevices. 6. LEDs: - Convert leds-mt6323.txt and merge into parent MT6397 PMIC DT schema. - Update LED binding. 7. Keys: - Add detailed descriptions for power and home keys. - Add compatible: mediatek,mt6358-keys. 8. 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". 9. Pinctrl: - Align to generic name "pinctrl" instead of "pin-controller". 10. Compatible: - Drop "mediatek,mt6357" since there is a separated DT Schema for PMIC MT6357. 11. 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.

[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. Changes for v4: - Remove "mediatek,mt6357" from PMIC's compatible string since there is a seperated DT schema for PMIC mt6357. Changes for v5: - Rebase to next-20240913 (linux-next/master). - Fix the "title" (device type) of mfd/mediatek,mt6397.yaml to "PMIC". - RTC: - Drop "start-year" - Regulators: - Add blank lines between description and properties. - Drop allOf for the $ref section on property. - clocks: - Fix no need '|' in descriptoin. - Add blank lines between description and properties. - Keys: - Drop compatible since these enums are already in $ref. - pinctrl: - Drop compatible since it is already in $ref. - examples: - Fix indentations for leds and keys. Changes for v6: - Commit message: - Add note for simplifying examples of mt6358 and mt6397. - examples: - Fix indentations for mt6323-keys. - MT6358 and MT6397: simplify settings in regulators. - Preserve "audio-codec", "clocks", "pinctrl", "rtc", and "keys" sections as they contain typical settings for different PMICs.
