+ * Name: stm32_registercallback
+ *
+ * Description:
+ *   Register a callback that that will be invoked on any media status
+ *   change.  Callbacks should not be made from interrupt handlers, rather
+ *   interrupt level events should be handled by calling back on the work
+ *   thread.
+ *
+ * Input Parameters:
+ *   dev -      Device-specific state data
+ *   callback - The funtion to call on the media change
+ *   arg -      A caller provided value to return with the callback
+ *
+ * Returned Value:
+ *   0 on success; negated errno on failure.
