When running without custom EDID settings, we get the top half of the screen flashing, bottom half is black.
This is the output from kmstest, kmsprint and dmesg | grep -i drmI tried to convert the old timings from fkms, but clearly they must've been wrong. The reason i get horrid fps is because we get errors on our custom EDID:
The datasheet for the display is talking about mipi timings, so I emailed the manufacturer about the board timings and got this back. I will compare these board timings to my edid and see what went wrong.
