Since the orion irq chip is based on irqchip_generic, it would be
perfect to have a generic irqchip binding to go along with
kernel/irq/generic-chip.c. Not sure if anyone has thought about this
before, but it looks like we can completely avoid using
arch/arm/plat-orion/irq.c and arch/arm/mach-kirkwood/irq.c if we
do that.
One more thing about the interrupt controller changes: The arm-soc
tree includes Grants "irqchip" branch, and the tegra/soc-drivers
and at91/dt branches are building on top of that. Please have a look
at what they do so you can do the same.
