Sorry, this v2 patch series is a bit messy: my git-send-email failed at patch 3
for some reason, so I posted patches 3-5 manually, but I forgot to add 'v2' to
the
subject of patch 4/5 and for some reason patch 3 now appeared twice. The
contents
of the patches is correct, though :-)

When parsing the reply of a DP_REMOTE_DPCD_READ DPCD command the
result is wrong due to a missing idx increment.
This was never noticed since DP_REMOTE_DPCD_READ is currently not
used, but if you enable it, then it is all wrong.

A big problem with DP CEC-Tunneling-over-AUX is that it is tricky
to find adapters with a chipset that supports this AND where the
manufacturer actually connected the HDMI CEC line to the chipset.
Add a mention of the MegaChips 2900 chipset which seems to support
this feature
From: Hans Verkuil
Now that the DisplayPort CEC-Tunneling-over-AUX drm+i915 support
has been merged in the mainline kernel it is time to roll this
out to nouveau and amdgpu as well.
The first patch is required for this: it adds checks that the drm_dp_cec
functions are called with a working aux
From: Hans Verkuil
If aux->transfer == NULL, then just return without doing
anything. In that case the function is likely called for
a non-(e)DP connector.
This never happened for the i915 driver, but the nouveau and amdgpu
drivers need this check.
The alternative would be to add this check in
