// This driver implements the Samsung pinctrl driver. It supports setting up of
// pinmux and pinconf configurations. The gpiolib interface is also included.
// External interrupt (gpio and wakeup) support are not included in this driver
// but provides extensions to which platform specific implementation of the gpio
// and wakeup interrupts can be hooked to.
