Hm! Thierry has recently submitted patches to make it easier for chips with banked IRQs to use the GPIOLIB_IRQCHIP.
Please look at the code in gpio/gpio-tegra186.c and see if you can use his approach.
As you can see this chip is using gpiochip_irq_map/unmap in its domain, and manipulates struct gpio_irq_chip directly.
I think the idea is to make it possible to use GPIOLIB_IRQCHIP for banked IRQs but the infrastructure is not yet inside the gpiolib so it is a bit taped on the side right now.
Yours, Linus Walleij
