[PATCH v6 0/5] mfd: tqmx86: new hardware and GPIO/I2C IRQ improvements/additions

[Matthias Schiffer <matthias.schiffer@ew.tq-group.com>]

Patch 1 adds support for 3 new TQMx86 COMs. GPIO support on SMARC
modules is currently limited (not all GPIOs can be controlled, pins use
incorrect default directions, IRQ configuration is handled incorrectly),
however this is a preexisting issue also effecting the TQMxE39S and
TQMxE40S, not only the new TQMxE41S. This will be addressed by a future
patch series involving both the TQMx86 MFD and GPIO drivers.

Patches 2-5 improve module parameter description and error handling of
GPIO IRQ configuration and add support for configuring an IRQ for the
TQMx86's OpenCores I2C controller in the same way.

Changelog:

v2: improve module parameter description (new patch 2, adjusted patch 5)
v3: replace IRQ 0 resource entries with empty placeholders to simplify
    error handling (patches 4 and 5)
v4: remove tqmx86_irq_to_irq_cfg() function (patch 3)
v5: move placeholders to the end of the resource arrays, use defines for
    index (patches 4 and 5)
v6: remove obsolete comment; refer to I2C controller as I2C1 (patch 5)
