v5.3-rc6 dmesg output with debug options

Hi,

I tested the following cable-combination with different monitors:

HDMI -> HDMI = BLACK Screen
HDMI -> DVI = BLACK Screen
mDP -> HDMI => BLACK Screen
mDP -> DP => Works

The issue is reproduceable on all of our Minix Z83-4 devices (different product
revisions). It does not appear on Minix N42C (different Intel CPU / GPU).

I attached the "dmesg" output generated with the specified boot options under
the v5.3-rc6 mainline kernel.
