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
