[PATCH v3 0/4] Update MT8188 OVL compatible from MT8183 to MT8195

[Jason-JH.Lin]

This patch series updates the compatible strings for the MediaTek OVL
in the MT8188 dts and the corresponding dt-binding.
The changes ensure that the MT8188 OVL device is correctly identified
and managed by the appropriate drivers.

The first patch is adding the MT8188 compatible strings, refer to:
- https://lore.kernel.org/all/20241218105320.38980-2-angelogioacchino.delregno@collabora.com/

The 2nd patch is resending the reviewed and acked patch from:
- https://lore.kernel.org/all/5d9e6f6c-604d-4e2d-a448-fc5b8bd24a75@collabora.com/
and rebase it to the latest linux-next-20241212.

The 3rd and the 4th patches are updating the mt8188.dtsi and mt8195.dtsi
according to the 1st patch.

---

Change in v3:
1. Add a dt-bindings ptach for MT8188 MDP3 OVL.

Change in v2:
1. Add missing mt8195 compatible in the beginning of compatible property.
2. Add fix patch to mt8195.

[PATCH v3 3/4] dts: arm64: mediatek: mt8188: Update OVL compatible from MT8183 to MT8195

[Jason-JH.Lin]

The OVL hardware capabilities have changed starting from MT8195,
making the MT8183 compatible no longer applicable.
Therefore, it is necessary to update the OVL compatible from MT8183 to
MT8195.
