This patch series add support for gpio driver in mediatek MT7621
SoC. This driver has been in staging for a while and after some
cleanups cycles we consider to give it a new try to get mainlined.

Changes in v4:
- Fix gpio banks naming issues
- Use custom xlate to be able to use only one node in DT.
- Add Reviewed-by: NeilBrown <neil at brown.name> to the patches.

Changes in v3:
- Fix added Makefile entry which was wrong.

Changes in v2 are the ones pointed out in previous mails:

- use bgpio_init
- avoid custom irq_domain using IRQF_SHARED and
gpiochip_set_chained_irqchip from GPIOLIB_IRQCHIP
- use only one node in the device tree making it simple
- Implement high and low level irqs
- avoid include gpio.h
- use builtin_platform_driver
- add COMPILE_TEST
- cleanups after this changes

Hope this helps and thanks in advance.

Best regards,
Sergio Paracuellos
