Actually I think I'm wrong about the interrupt-controller changes in patches
0002 and 0003.

You are. Looking at the datasheet, the GPIOs have interrupt capability.
GPIO controllers are typically both an interrupt client and provider.

Thanks for the clarification.

I still think the patch 0001 is required. The precious and volatile 
ranges are broken.
