    gpiolib: add drivers/gpio directory · a9c5fff5
    David Brownell authored
    Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO
    expanders.  It will be populated by later patches.
    This won't be the only place to hold such gpio_chip code.  Many external chips
    add a few GPIOs as secondary functionality (such as MFD drivers) and platform
    code frequently needs to closely integrate GPIO and IRQ support.
    This is placed *early* in the build/link sequence since it's common for other
    drivers to depend on GPIOs to do their work, so they must be initialized early
    in the device_initcall() sequence.
