What's the guaranteed width of atomic_t? IIRC a long time ago
changes v4:
- use IRQ_NOAUTOEN to not enable IRQ by default
- rename gpio_ from name pattern and make this driver work any IRQ
source.
changes v3:
- convert counter to atomic_t
changes v2:
- add commas
- avoid possible unhandled interrupts in the enable path
- do not use of_ specific gpio funct
