dmesg-experiment-from-sleep

Hmmm, so I did an experiment, with the external monitor removed and device
screen active (backlight is on), I closed the lid and it supposedly goes into
sleep mode (it seem to indicate with a sine wave brightness thing on the power
button LED). When I opened it again the screen flashed a couple of times. You
can see it in the attached dmesg logs following the MIPI_SEQ_* executions. This
is still on the drm-tip kernel. I think this is interesting because somehow
something is triggering DSI enable and it keeps retrying something.
