    pinctrl: add a driver for the U300 pinmux · 98da3529
    Linus Walleij authored
    This adds a driver for the U300 pinmux portions of the system
    controller "SYSCON". It also serves as an example of how to use
    the pinmux subsystem. This driver also houses the platform data
    for the only supported platform.
    
    This deletes the old U300 driver in arch/arm/mach-u300 and
    replace it with a driver using the new subsystem.
    
    The new driver is considerably fatter than the old one, but it
    also registers all 467 pins of the system and adds the power
    and EMIF pin groups and corresponding functions. The idea
    is to use this driver as a a reference for other
    implementation so it needs to be as complete and verbose
    as possible.
