[PATCH v6 0/7] drm/mediatek: Add mt8195 DisplayPort driver

[Guillaume Ranquet]

Hi everyone,

I'm taking over the subject for the time being as Markus is on vacation.

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 v6, I've ported fixes from the mediatek team to this series, which can be found in this
vendor tree:
- https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/3252762/5

I haven't taken care of the comment made by Vinod in v5 [1] where he asks to use phy_get()
instead of fiddling with the platform data. This will be addressed in v7, Sorry about that.
