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.

Say yes here to support GPIO interface on ST-Ericsson U300.
|

The names of the two IP block variants supported are
|
|
COH 901 335 and COH 901 571/3. They contain 3, 5 or 7
|
|
ports of 8 GPIO pins each.
