[PATCH 3/6] gpio: Add GPIO driver for Nintendo Wii

2018-01-14 Thread Jonathan Neuschäfer
The Nintendo Wii's chipset (called "Hollywood") has a GPIO controller that supports a configurable number of pins (up to 32), interrupts, and some special mechanisms to share the controller between the system's security processor (an ARM926) and the PowerPC CPU. Pin multiplexing is not supported.
