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.
   - Add a new 'mt6359-regulator' to the compatibles of regulators.

Why?

     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

Why?
.

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.

No, this cannot be true. Schema is incomplete for listed compatibles.

I saw now your patch for ASoC, so this is fine.

All my other questions stay valid - why are you adding new devices in
patch which is supposed to be ONLY conversion.


Ok, I'll drop adding new devices from other reviewed patch for this ONLY
conversion.

+      compatible:
+        oneOf:

+              - mediatek,mt6358-sound
+              - mediatek,mt6359-codec

There was no such compatible.

Why do you add non-existing compatibles during conversion?


Same here, will drop it in this conversion.


Best regards,
Krzysztof
