[PATCH 00/21] drm/bridge: tc358767: DP support

[Tomi Valkeinen]

Hi,

tc358767 bridge was originally implemented for eDP use with an embedded
panel. I've been working to add DP support, and this series is the
result. I did have a lot of issues with link training, but with these,
it's been working reliably with my devices.

A downside on my hardware is that there's no HPD interrupt, so this uses
polling. I believe the polling support could be improved by using the
INTSTS_G register to find out it there has been plug-ins/outs, but for
now this does the HPD handling the naive way.
