[PATCH v2 0/8] drm/bridge: add bus flag support

From: Stefan Agner
Date: Wed Sep 12 2018 - 14:32:34 EST


This v2 shifted a bit more to rework bridge timing support. While
my use case mainly cares about complete bus flag support, it seems
to me that bus timings have ended up to be more complex than
necessary. Patch 2/3 are an attempt to simplify bus timings. This
also aligns bridge timings with how display timings are specified
today.

@Linus Walleij, Laurent Pinchart: Since you have been involved in
the initial bus timings discussion, I would like to have your Ack
on at least patch 2/3... If we want to keep the setup/hold timings,
the patchset should also work without those two patches.
