arch/powerpc now uses virtual interrupts instead of the physical interrupts used in arch/ppc. So you can't just use the physical interrupt number in your request_irq() anymore. You need an of-platform driver to generate the virtual interrupt from the physical interrupt in the device-tree (irq_of_parse_and_map()). And you need to add this new node with the interrupt property to your device-tree of course.
