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. With these patches, tests in IGT such as kms_pipe_crc_basic and kms_plane do pass on RK3288.
