Hum? The driver you're touching is a GPIO driver, while
drivers/irqchip/irq-orion.c is an interrupt controller driver. The
gpio-mvebu driver can be used on all mvebu platforms that are DT
capable, but the main interrupt controller is different from one
platform to another: we already have irq-armada-370-xp.c for Armada
370/XP, while Sebastian's irq-orion.c is for older families of SoCs.

Or maybe I'm missing something?

Thanks!

Thomas
