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/20210825144833.7757-1-jason-jh.lin@me... - Add MediaTek SoC DRM (vdosys1) support for mt8195 https://lore.kernel.org/linux-mediatek/20210825100531.5653-1-nancy.lin@media...

Thanks in advance for any feedback and comments.
