+ Say yes here to select AT91 PIO GPIO driver. AT91 PIO
+ controller manages up to 32 fully programmable input/output
+ lines. Each I/O line may be dedicated as a general-purpose
+ I/O or be assigned to a function of an embedded peripheral.
+ The assignment to a function of an embedded peripheral is
+ the responsibility of AT91 Pinctrl driver. This driver is
+ responsible for the general-purpose I/O.
