    pinctrl: add samsung pinctrl and gpiolib driver · 30574f0d
    Thomas Abraham authored
    Add a new device tree enabled pinctrl and gpiolib driver for Samsung
    SoC's. This driver provides a common and extensible framework for all
    Samsung SoC's to interface with the pinctrl and gpiolib subsystems. This
    driver supports only device tree based instantiation and hence can be
    used only on those Samsung platforms that have device tree enabled.
    This driver is split into two parts: the pinctrl interface and the gpiolib
    interface. The pinctrl interface registers pinctrl devices with the pinctrl
    subsystem and gpiolib interface registers gpio chips with the gpiolib
    subsystem. The information about the pins, pin groups, pin functions and
    gpio chips, which are SoC specific, are parsed from device tree node.
