I am also interested in helping, and I too, would like some guidance
as how to help.

I am just finishing up a series of extensive tests on the 5.4 kernel
for a few different devices that I maintain.  I wanted to get it done
while 5.4 was still in RC status since it'll be the next LTS kernel,
and some of the regressions holding me back were the removal of video

Now that I think it's behind me, I have some cycles to spend on
working on this as well.  I only have an AM3517, OMAP3530, and DM3730.
  Normally I avoid X due to the overhead, so for me being able to show
it with the DRM/FBDEV is preferred.

It's 3:48am for me, so I'm going back to bed.
