[PATCH v2 0/6] serial/gpio: exar: Fixes and support for IOT2000

[Jan Kiszka <jan.kiszka@siemens.com>]

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 v2:
 - dropped already merged patches
 - switched to platform_data structure for exar <-> gpio driver
   communication
 - use dmi_check_system() to express platform match
 - adjusted bit logic style in exar_get_direction/value
