+	  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
