I just remembered, the commits that make the generic irqchip work with linear irq domains are in tip/irq/core so this won't work on pinctrl/devel or gpio/next branches. How would you like that handled? I'm happy to write a patch to convert to generic irqchip ready to be applied later (e.g. for v3.12). Cheers James
