That RS485 addition to PL011 using GPIOs is a bit hacky but
looks like very useful for industrial applications.
Ladislav, have you been in contact with Hilscher?

They have a mail address github@hilscher.com, let's knock
on the door and see if somebody answers it :D

I'd personally be able to take a stab at converting this machine
to device tree and multiplatform if I only had access to the
hardware, as it seems to be in the same class as EP93xx
and MOXA ART: deployed in industrial systems as we speak.

Yours,
Linus Walleij
