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
