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