    Documentation: gpiolib: document new interface · fd8e198c
    Alexandre Courbot authored
    gpiolib now exports a new descriptor-based interface which deprecates
    the older integer-based one. This patch documents this new interface and
    also takes the opportunity to brush-up the GPIO documentation a little
    The new descriptor-based interface follows the same consumer/driver
    model as many other kernel subsystems (e.g. clock, regulator), so its
    documentation has similarly been splitted into different files.
    The content of the former documentation has been reused whenever it
    made sense; however, some of its content did not apply to the new
    interface anymore and have this been removed. Likewise, new sections
    like the mapping of GPIOs to devices have been written from scratch.
    The deprecated legacy-based documentation is still available, untouched,
    under Documentation/gpio/gpio-legacy.txt.
