    Subject[PATCH 0/6] Nintendo Wii GPIO driver
    Date
    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.

    Jonathan Neuschäfer (6):
    resource: Extend the PPC32 reserved memory hack
    powerpc: wii: Explicitly configure GPIO owner for poweroff pin
    gpio: Add GPIO driver for Nintendo Wii
    dt-bindings: gpio: Add binding for Wii GPIO controller
    powerpc: wii.dts: Add ngpios property
    powerpc: wii.dts: Add GPIO line names
