Sorry for that.

I haven't tested the patch yet. I'll try to do that in the next few
days. Sebastian reviewed it quite well so I think as soon as I've seen
the test run on one or two platforms I can merge it. Same is true for
your documentation patch that fixes the typos.

The display arrived today. Although still a bit distorted, I get at
least an output on FreeBSD with an adapted device tree. Bad news is: No
output with your fb-sample. The backlight didn't light up (which is
expected) and I don't get any output if I search with a flashlight. I'll
try to hack in a backlight soon but normally if there is something on
the screen it should be at least slightly visible with enough light.

That's a good gap filler and it's great and useful if you contribute to
the documentation. But at least the first tests with the display didn't
give much results. So most likely you should try some other methods of
analysis. I think you had thought about debugging the FreeBSD kernel to
find out the differences?
PS: Sorry for sending it twice to all directly addressed. I used the
wrong "from" address the first time so it didn't reach the list.
