[v3,0/6] drm/mediatek: Add mt8195 DisplayPort driver

Hi everyone,

this series is built around the DisplayPort driver. The dpi/dpintf driver and
the added helper functions are required for the DisplayPort driver to work.

For v3 I fixed/removed obsolete TODOs in the driver code and fixed one feedback
comment regarding a 'DRM_' prefix for the CEA_SAD defines.

The series is still based on v5.15-rc1 but also applies cleanly on linux-next
at the moment. There still is a functional dependency on many different patches
pulled in through the main two dependencies, vdosys0 and vdosys1, but I still
don't have a stable and clean base with these.

Note: This patch series is currently tested on v5.10 and I am still working on
testing it on v5.15.

Dependencies:
- Add Mediatek Soc DRM (vdosys0) support for mt8195
  https://lore.kernel.org/linux-mediatek/[e-mail]/
- Add MediaTek SoC DRM (vdosys1) support for mt8195
  https://lore.kernel.org/linux-mediatek/[e-mail]/

v1  - https://lore.kernel.org/linux-mediatek/[e-mail]/
v2  - https://lore.kernel.org/linux-mediatek/[e-mail]/

Thanks in advance for any feedback and comments.

Best,
Markus
