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".

9. Compatible:
   - Drop "mediatek,mt6357" since there is a separated DT Schema
     for PMIC MT6357.

10. 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.

Changes for v1:
 - This patch depends on conversion of mediatek,mt6397-regulator.yaml
   [1] https://lore.kernel.org/lkml/20240807091738.18387-1-macpaul.lin@mediatek.com/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.

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.

Unreviewed. This is incomplete.

Do not send incorrect patches and then followups for them. Just fix the
incorrect patch before it gets applied.

NAK

Follow up patch pointed out this is incorrect. I don't understand this
concept of sending knowingly incorrect code, so please sort it out at v7.

Sorry I didn't know mt6359-codec and mt6358-sound are similar device
until Sept 26 (just yesterday) when I was reviewing the DT
bindings. Until I've found the previous DT Schema of mt6359-codec 
incorrect.
See [1] 
https://lore.kernel.org/linux-arm-kernel/20240926092519.6556-3-macpaul.lin@mediatek.com/T/
and [2] 
https://lore.kernel.org/all/20240926092519.6556-2-macpaul.lin@mediatek.com/

And.. I don't understand, the origin this patch v6 should be a text file
conversion, shouldn't we keep the origin content just a conversion and
trying not to broken other relate modules?

Please help to indicates what is a better approach here:

Should I merge the properties of mt6359-codec, mt6358-sound, and 
mt6397-codec
together and put them all into to mt6359.yaml and redo the converting of 
mfd/medaitek,mt6397.yaml?

That will be much simpler for the audio-codec node for mediatek,mt6397.yaml.
However there will be a little mismatch from the origin text file.

Thanks

The conversion should be correct. Correct means each compatible has a
schema ending with additional/unevaluatedProperties: false.

If you need to change this binding to "true", it means above statement
was not fulfilled. You did not write proper conversion.

... or I do not understand what you wanted to achieve with the other patch.

Not sure, I don't know. Are these different devices? How are they
related? I expect you to know this, not me.

The problem is that you send a patch having a finished schema for child
node and then - in next patch in different patchset (!!!) - immediately
change it to false.

So the first code, which was not even merged, is incorrect. This is
heavily misleading.

-Device Tree Bindings for LED support on MT6323 PMIC
-
-MT6323 LED controller is subfunction provided by MT6323 PMIC, so the LED
-controllers are defined as the subnode of the function node provided by MT6323
-PMIC controller that is being defined as one kind of Muti-Function Device (MFD)
-using shared bus called PMIC wrapper for each subfunction to access remote
-MT6323 PMIC hardware.
-
-For MT6323 MFD bindings see:
-Documentation/devicetree/bindings/mfd/mt6397.txt
-For MediaTek PMIC wrapper bindings see:
-Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml
-
-Required properties:
-- compatible : Must be one of
-  - "mediatek,mt6323-led"
-  - "mediatek,mt6331-led"
-  - "mediatek,mt6332-led"
-- address-cells : Must be 1
-- size-cells : Must be 0
-
-Each led is represented as a child node of the mediatek,mt6323-led that
-describes the initial behavior for each LED physically and currently only four
-LED child nodes can be supported.
-
-Required properties for the LED child node:
-- reg : LED channel number (0..3)
-
-Optional properties for the LED child node:
-- label : See Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger : See Documentation/devicetree/bindings/leds/common.txt
-- default-state: See Documentation/devicetree/bindings/leds/common.txt
-
-Example:
-
-	mt6323: pmic {
-		compatible = "mediatek,mt6323";
-
-		...
-
-		mt6323led: leds {
-			compatible = "mediatek,mt6323-led";
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			led@0 {
-				reg = <0>;
-				label = "LED0";
-				linux,default-trigger = "timer";
-				default-state = "on";
-			};
-			led@1 {
-				reg = <1>;
-				label = "LED1";
-				default-state = "off";
-			};
-			led@2 {
-				reg = <2>;
-				label = "LED2";
-				default-state = "on";
-			};
-		};

+description: |
+  MT6397/MT6323 is a power management system chip.
+  Please see the sub-modules below for supported features.
+
+  MT6397/MT6323 is a multifunction device with the following sub modules:
+  - Regulators
+  - RTC
+  - Audio codec
+  - GPIO
+  - Clock
+  - LED
+  - Keys
+  - Power controller
+
+  It is interfaced to host controller using SPI interface by a proprietary hardware
+  called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap.
+  See the following for pwrap node definitions:
+  Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml
