+	  Say Y here to add some extra checks and diagnostics to GPIO calls.
+	  The checks help ensure that GPIOs have been properly initialized
+	  before they are used and that sleeping calls aren not made from
+	  nonsleeping contexts.  They can make bitbanged serial protocols
+	  slower.  The diagnostics help catch the type of setup errors
+	  that are most common when setting up new platforms or boards.
