Hello linux-arm-kernel,
GPIODEV API: Support for ARM PXA2xx CPU. Implementation is based on
Generic GPIO API. Generally, GPIODEV implementation should be provided
by device driver. But CPU-builtin devices in the current code are
treated is special manner ("arch devices"), so this approach is
followed for GPIODEV too.
