Subject: [PATCH v2 0/5] drm/dp: Implement CRC debugfs API

Hi,

this series builds up on the API for exposing captured CRCs through
debugfs.

It adds new DP helpers for starting and stopping CRC capture and gets
the Rockchip driver to use it.

Also had to add a connector backpointer to the drm_dp_aux struct so we could
wait for the right vblank and store the CRCs afterwards, I will be glad
to hear about better alternatives.

Thanks,

Tomeu
