Just one question, when you say "super-complex irqchip in use", do you mean
I could use another (simplest) solution to handle this EXTI controller?

I don't know, GPIOLIB_IRQCHIP is to be used for some specific
cases documented in Documentation/gpio/driver.txt.

For anything complex, we either need to have this hairy code
or invent new abstractions.

For now, I assume this is needed...
