Subject: [PATCH v2 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 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
