+ * Description:
+ *   Sets/clears GPIO based event and interrupt triggers.
+ *
+ * Input Parameters:
+ *  - pinset: gpio pin configuration

+ *  - event:  generate event when set
+ *  - func:   when non-NULL, generate interrupt
+ *  - arg:    Argument passed to the interrupt callback
+ *
+ * Returned Value:
+ *   Zero (OK) on success; a negated errno value on failure indicating the
+ *   nature of the failure.
