[PATCH 00/11] drm: MediaTek DisplayPort cleanups and MT8196 eDP

[AngeloGioacchino Del Regno]

This series performs some very much needed cleanups to the MediaTek
DisplayPort driver, including a fix for the audio codec and PHY driver
unregistration, a refactor to finally correctly use the PHY (!) and
introduces support for the Embedded DisplayPort (eDP) IP in MT8196.

Note that this deprecates the nvmem related properties in this driver
because those are NOT related to the DisplayPort IP, but rather to the
DisplayPort PHY, and were therefore transferred there instead (code in
a different series, updating the PHY driver).

On legacy devices, this driver was carefully tested with both NEW and
OLD devicetrees, so both with the new, proper PHY usage, and with the
old platform device registration strategy and eFuse retrieval from DP
instead of PHY driver.

This was also successfully (manually) tested in a kernel that misses
the PHY driver updates on devices using old devicetrees (mt8195/88)
and no regressions were experienced.
