I also tested this series on an Exynos5800 Peach Pi Chromebook, using
Heiko's branch [0] that is based on today's mainline (968f3e374fa).

I've seen no regressions with these patches, DP is working fine and
also comes up after a S2R and DPMS on/off using the exynos-drm sysfs.

NOTE: I had to cherry-pick a SPI core fix [1] in order to make the Pi
to boot. Not related to this series of course but I just mention it in
case someone else wants to do the same test on this machine.

Same here, this is the second time I tested this series (first time was
v6 on October 25 [2]) and I think that has been out there for too long.
