+	  Say yes here to enable support for generic GPIO cascade.
+
+	  This allows building one-to-many cascades of GPIO lines using
+	  different types of multiplexers readily available. At the
+	  moment only input lines are supported.
+
+	  To build the driver as a module choose 'm' and the resulting module
+	  will be called 'gpio-cascade'.
