[PATCH v3 0/8] staging: mt7621-gpio: last cleanups

[Sergio Paracuellos]

After submiting this driver to try to get mainlined and get
out of staging some new cleanups seems to be necessary.
According to this main of Linus Walleij:

http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-June/121742.html

this series tries to fix all of the issues in order to send
v2 and give it a new try. Because I don't have to hardware to
test my changes I send new cleanups first in staging to make
easier to NeilBrown test it and get a feedback about them.

Changes in v3:
    - PATCH 7: refactor irq_type to make better code.
    - Add PATCH 8 avoiding the use of custom domain and requesting
      manually a 'IRQF_SHARED'. It should be working now??

Changes in v2:
    - Patch where GPIOLIB_IRQCHIP was used avoiding
      the use of a custom irq domain has been dropped to
      be sure after this changes all is working properly.
      (This was PATCH 7 in previous series)
    - PATCH 1:
         * avoid introducing new macros and use 'bank'
           field of mtk_gc with register offset.
         * Make correct use of bgpio_init passing new
           void __iomem pointers instead of use the
           macros.
    - Previous series PATCH 8 now is PATCH 7. Avoid the
      use of a switch-case statement which was wrong and
      distinc if we have RISSING AND FALLING EDGE interrupt
      or HIGH LOW level ones. This last two are exclusive and
      cannot be generated at the same time.

Hope this helps.

Thanks in advance.

Best regards,
    Sergio Paracuellos
