[PATCH v5 0/7] 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.

In v5 I reworked the mtk-dpi so that dpintf is only using the same three clocks
as dpi does. This lead to the removal of the separate dpintf binding document.
Also there are minor updates to the mtk-dp binding and driver.

The series is based on v5.15-rc1 but also applies cleanly on linux-next.
Note: This patch series is currently tested on v5.10 and I am still
working on testing it on v5.15.

Thanks in advance for any feedback and comments.

Best,
Markus
