[PATCH v2 0/6] MediaTek devicetree/bindings warnings sanitization second round

[Julien Massot]

This patch series continues the effort to address Device Tree validation warnings for MediaTek platforms, with a focus on MT8183. It follows the initial cleanup series by Angelo (https://www.spinics.net/lists/kernel/msg5780177.html)

The patches in this set eliminate several of the remaining warnings by improving or converting DT bindings to YAML, adding missing properties, and updating device tree files accordingly.

Changes in v2:

- Restrict power-domain usage to mediatek,mt8183-mfgcfg only
- Add the MT8183 AFE binding before audiosys (it is referenced in the example) and include the memory-region property
- Rename binding files to align with the compatible name
- Drop former patch 7/9 (already applied via the pinctrl tree)
- Drop patches 8/9 and 9/9 until we decide how to represent R0 and R1 values

[PATCH v2 1/6] dt-bindings: clock: mediatek: Add power-domains property

[Julien Massot]

The mt8183-mfgcfg node uses a power domain in its device tree node.
To prevent schema validation warnings, add the optional `power-domains`
property to the binding schema for mediatek syscon clocks.

Fixes: 1781f2c46180 ("arm64: dts: mediatek: mt8183: Add power-domains property to mfgcfg")

Checkpatch complains here, but more important - where is explanation of
dropped tag?

But this tag appeared? It wasn't even given!

You remove public tags and add tags never given on the lists.

I found Angelo's tag, but still dropping other acks is not explained.

Right the proper tag is 
Fixes: 1781f2c46180 ("arm64: dts: mediatek: mt8183: Add power-domains properity to mfgcfg")

Regarding the tags: in v2 the patch changed quite a lot after I applied
Angelo's suggestion, so I decided to drop Rob’s Acked-by as it no longer
applies to the new version. I should have explained this in the changelog.

[PATCH v2 2/6] ASoC: dt-binding: Convert mt8183-afe-pcm binding to YAML

[Julien Massot]

Convert the MediaTek MT8183 AFE PCM Device Tree binding from the old
.txt format to YAML schema format to improve validation.

While converting, also document all clock inputs and memory-region
used by the AFE block.

[PATCH v2 3/6] dt-bindings: arm: mediatek: Support mt8183-audiosys binding variant

[Julien Massot]

Update the mediatek,audsys binding to support the mt8183-audiosys
compatible, which uses a different audio controller binding
(mediatek,mt8183-audio.yaml) compared to the legacy mt2701-audio
controller.

[PATCH v2 4/6] arm64: dts: mt8183: Rename nodes to match audiosys binding schema

[Julien Massot]

The binding for "mediatek,mt8183-audiosys" expects an audio-controller
node inside the audiosys block. Rename the nested AFE node from
"mt8183-afe-pcm" to "audio-controller" accordingly.

Also rename the audiosys node itself from "audio-controller" to
"clock-controller" to better reflect its function.

[PATCH v2 5/6] dt-bindings: sound: Convert MT8183 DA7219 sound card bindings to YAML

[Julien Massot]

Convert the Device Tree binding for MT8183-based boards using the
DA7219 headset codec and optional MAX98357, RT1015 or RT1015P speaker
amplifiers from the legacy .txt format to YAML schema.

This improves binding validation and removes DT schema warnings
for boards using these audio components.

In the subject (on all the patches), avoid saying 'binding' twice and I 
prefer 'DT schema' over YAML. Lot's of things are YAML, but only one 
thing is DT schema.

Ok, I fixed all the commit messages and replaced 'YAML' by 'DT schema'.

What's the story with interdepenencies between the patches in this
series?

Please fix your mail client to word wrap within paragraphs at something
substantially less than 80 columns.  Doing this makes your messages much
easier to read and reply to.

Thanks for the feedback, and apologies for the long lines — I have fixed
my mail client for follow-ups.

Regarding interdependencies in the series:

  * Patch 1/6 can be picked up independently.
  * Patch 2/6 is standalone.
  * Patch 3/6 depends on 2/6.
  * Patch 4/6 fixes the DTS node name as expected by 3/6.
  * Patches 5/6 and 6/6 are independent.

So the only ordering requirement is that 2/6 should land before 3/6, with
4/6 included as well to avoid introducing a temporary new DTB warning.
All others can be applied in any order

Regards,
Julien
