[v8,0/19] drm/mediatek: Add mt8195 DisplayPort driver

Message

Guillaume Ranquet Feb. 18, 2022, 2:54 p.m. UTC

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.

Changes from v7:

As requested from CK Hu, I've split the DP driver into multiple patches
with initial support for eDP, then DP and finally Audio.

the dpi patches have also been split to isolate all the boolean/config
options added to the board config structure.

I've thus removed the "Reviewed-By" tags (from AngeloGioacchino Del Regno) touching these patches.

I've also included 2 patches from Jitao to the series:
  drm/mediatek: add hpd debounce
  drm/mediatek: change the aux retries times when receiving AUX_DEFER
