I don't get this, if the subarch has deps in place for IRQCHIP and OF_IRQ just move the implementation to drivers/irqchip/foo.c edit drivers/irqchip/Makefile to compile the file for ARCH_FOO. What would the problem be? It's not like having the irqchip in the object is optional...
I would prefer if you augment the code to use IRQCHIP_DECLARE() so you can get rid of all the criss-cross calls, but this init contains a comment saying that GPIO has to be up before you initialize the irq_chip, can you please explain why it's like that?
Another way is to create a separate Kconfig entry for it in drivers/irqchip/Kconfig if you want the set-up to be more distributed, but that is usually just done when the irqchip is used on more than one platform.
Yours, Linus Walleij
