[v2,0/6] 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 v2 I rebased the series on top of v5.15-rc1. There still is a functional
dependency on many different patches pulled in through the main two
dependencies, vdosys0 and vdosys1, but I wasn't able to get a clean base with
these patches yet so to continue improving this series in the meantime, I
decided to go with v5.15-rc1 as a base. The main potential merge-conflict
points of this series with other series are mtk_drm_drv.c and
mtk_drm_ddp_comp.* etc. which should be easy to resolve later on.

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

- Add MediaTek SoC DRM (vdosys1) support for mt8195

Older revisions:

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

Thanks in advance for any feedback and comments.

Best,
Markus
