Subject[PATCH v2 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.

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.

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
