This looks like textbook example of a driver that can use CONFIG_GPIO_GENERIC

select GPIO_GENERIC
See e.g. drivers/gpio/gpio-ftgpio010.c for an example of how to use bgpio_init() to set up the helper library to handle the GPIO side of things and combine it with an irqchip. You get get/set_multiple() for free with this approach. Also see documentation for bgpio_init() in drivers/gpio/gpio-mmio.c.
