+
+ - reg: a total of 3 register base addresses, the first one must be the
+   Switch Register Access block base, the second is the port 5/4 mux

+   and status register base address.
+
+ - interrupts: a total of 13 interrupts must be specified, in the following
+   order: port 0-5, 7-8 link status change, then the integrated PHY interrupt,
+   then the timestamping interrupt and the sleep timer interrupts for ports
+   5,7,8.
