This series adds a driver for the GPIO controller used in the Nintendo Wii game console. The driver itself, and the related devicetree work should be pretty uncontroversial, but due to the system architecture of the Wii, I also had to extend an old resource allocation hack to kernel/resource.c: On the Wii, there are two separate RAM ranges, with MMIO right in the middle, but AFAIK, Linux on PPC32 doesn't support discontiguous memory properly. So the hack is to allocate one big RAM range with a hole (marked as reserved memory) for MMIO in the middle. Because this series touches different subsystems (GPIO, DT, core resource management), I guess it should be picked up patch-by-patch by the different maintainers. The main difference between v2 and the previous version is that I rewrote the driver on top of the GPIO_GENERIC library, saving 60 lines of code.
