It seems like all the GPIO > drivers that use irq domains do it the way I was doing it It is a well known problems that the kernel contain many bad examples. When in doubt ask for a good example to be provided.

I guess this is a general direction all the > other drivers will be encouraged to go in also? Yes. The reason is that it should be possible to reques an IRQ from an irqchip no matter whether the gpio_to_irq() function was called first, as the APIs are orthogonal.
