I would say that setting the interrupt should deal with all the necessary configuration to get that interrupt working. In the case of pretty much all of the SoCs I have been involved with have always set the GPIO's function to allow the interrupt to pass through.

That's what Stephen is trying to do, essentially. It's looking like it's more sensible to fix it in the Tegra interrupt drivers, though.
