[PATCH v4 0/9] serial/gpio: exar: Fixes and support for IOT2000

[Jan Kiszka <jan.kiszka@xxxxxxxxxxx>]

This makes the gpio-exar driver usable, which was prevented by a number
of fatal bugs, and adds support for the SIMATIC IOT2040 to the 8250-exar
driver and, indirectly, to gpio-exar as well. It's a cross-subsystem
series, so I'm also cross-posting to the serial and gpio lists.

Changes in v4:
 - fold v3 patches 8 and 9 together
 - use DT-like property names

I would suggest to send this series as a whole through one branch,
either gpio after receiving acks from Greg or serial (most acks from
Linus are there).
