[PATCH v2 0/5] vf610: Add GPIO support

[Stefan Agner]

These include the review of Linus and Bill. I also added a patch
creating the Documentation for the GPIO/PORT module (altough, the
device tree bindings are already in use and not part this patch).
Then there is a small extension to Colibri VF61 device tree, and
because of that change I refrained to add Linus Acked-By to the DTS
patch. Linus, if you agree, can you send the Ack for that patch
again?

Changes in v2:
- Use bit operations in GPIO driver
- Use VF610_ prefix for GPIOS_PER_PORT define
- Drop irq in drivers struct
- Use arch/subsys_initicall for GPIO/pinctrl driver
- Fix log message title
- Add documentation for GPIO/PORT module bindings
- Extended GPIO device tree bindings for Colibri VF61
