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
