+ * things like driving strength and pullup/pulldown.
+ * - Each pad can have but not necessarily does have an output routing register

+ *
+ * The three register sets do not have a fixed offset to each other,
+ * hence we order this table by pad control registers (which all pads
+ * have) and put the optional i/o routing registers into additional
+ * fields.

+ * The naming convention for the pad modes is MX35_PAD_<padname>__<padmode>
