This looks very much like a memory-mapped standard GPIO controller,
use drivers/gpio/gpio-generic.c with some IRQ add-on, compare
to any other driver selecting GPIO_GENERIC for guidance:
drivers/gpio/gpio-74xx-mmio.c, gpio-dwapb.c etc.

You mean I must rewrite to use GPIO_GENERIC follow gpio-74xx-mmio.c,
gpio-dwapb.c ?

Yes.
