Same here on my rk3568, also with a samsung monitor. Was it 4k@60Hz or
4k@30Hz? If the former, could you give 4k@30Hz a try? That mode works
well here.

Yeah, splitting up the series makes sense. At the moment I have it all
in one series to ease others testing it.

At least there are patches in it that I have in my series as well and
keep popping up everywhere like "drm/rockchip: dw_hdmi: Use
auto-generated tables" and "drm/rockchip: dw_hdmi: Set cur_ctr to 0
always"
