This is the first series of improvements to the tqmx86 GPIO driver,
which fixes some long-standing bugs - in particular, IRQ_TYPE_EDGE_BOTH
can never have worked correctly.

Other patches in the series are code cleanup, which is included as it
makes the actual fixes much nicer. I have included the same Fixes tag in
all commits, as they will need to be cherry-picked together.

A second series with new features (changing GPIO directions, support
more GPIOs on SMARC TQMx86 modules) will be submitted when the fixes
have been reviewed and merged.

Gregor Herburger (1):
  gpio: tqmx86: fix typo in Kconfig label

Matthias Schiffer (7):
  gpio: tqmx86: introduce shadow register for GPIO output value
  gpio: tqmx86: change tqmx86_gpio_write() order of arguments to match
    regmap API
  gpio: tqmx86: introduce _tqmx86_gpio_update_bits() helper
  gpio: tqmx86: add macros for interrupt configuration
  gpio: tqmx86: store IRQ triggers without offsetting index
  gpio: tqmx86: store IRQ trigger type and unmask status separately
  gpio: tqmx86: fix broken IRQ_TYPE_EDGE_BOTH interrupt type
