EDID file

Don't know if this helps but ALL kernels seem affected by not being able to
grab EDID on startup but the changes after 4.18 break something further as =
to
make the display unusable by changing the default behavior of the panel's m=
ode
without EDID.

Is what happens when I set the edid manually from the kernel commandline.

Setting it manually freaks out newer kernels and my display won't modeset
properly making it a mess but on 4.18 it seemed to drop this.

Any debug patches I can run to help you guys figure it out?
I have included my EDID file if you want to run it through anything to see =
what
breaks.
