How would I do that? I can very well read the kernel sourcecode, but I know
nothing about UART programming and stuff.

I tried DT, but as you can see in bug #58611 it currently doesn't work for me,
even with the 3.10 release candidate. But if I understand you correctly, in the
current situation DT wouldn't really help me.

If you have some patches for the panda-es, I would be happy to test them!

Greets,
