Subject: [PATCH v3 0/6] MediaTek devicetree/bindings warnings sanitization
 second round

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 DT schema, adding missing properties,
and updating device tree files accordingly.

Changes in v3:
- Mostly cosmetic updates.
- Patch 1/6: fixed the commit reference in the 'Fixes' tag.
- Patch 1/6: not mentioned in v2, but this patch changed quite a lot
  since v1 after applying Angelo's suggestions, so I dropped Rob's
  'Acked-by' tag.
- Renamed commits from "YAML" to "DT schema", and avoided repetition
  of "bindings".
- Patch 2/6: switched to the generic node name "audio-controller".
- Link to v2:
  https://lore.kernel.org/r/20250820-mtk-dtb-warnings-v2-0-cf4721e58f4e@collabora.com

Merge strategy:
- 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.

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
