After submiting this driver to try to get mainlined and get out of staging some new cleanups seems to be necessary. According to this mail of Linus Walleij:
http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-June/121742.html and this mail os Rob Herring: http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-June/121974.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 v4: - Add "last minor cleanups" series to the same patch series. - Update Kconfig being more specific in description and help about the SoC. - Update dt-bindings, device tree and code to don't use banks in the device tree assuming this SoC has 3 banks with 32 gpios each. 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.
