+ * Outputs C and D can each provide two different clock outputs C1/D1 or

+ *
+ * PA11 defaults to output low (or 0) in the i/o port config table above.
+ *
+ * Output A provides a 100MHz for the High Speed Serial chips. Output B
+ * provides a 3.6864MHz clock for more accurate asynchronous serial bit
+ * rates. Output C is routed to the mezzanine connector but is currently
+ * unused - both C1 and C2 are set to 16MHz. Output D is used by both the
