Subject: [PATCH v3 00/10] serial/gpio: exar: Fixes and support for IOT2000

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 v3:
 - fix MPIO state for Commtech adapters (regression of merged patch from
   previous round)
 - do not create gpio device for Commtech adapters
 - switch back to device properties
 - pass parent reference via device.parent instead of platform data
 - use dmi_system_id table instead of open-coded matching
 - address some smaller review remarks
 - fix reading back of rs485 state
 - adjust parenthood of exar gpiochip
