+   i) Freescale QUICC Engine module (QE)
+   This represents qe module that is installed on PowerQUICC II Pro.
+   Hopefully it will merge backward compatibility with CPM/CPM2.
+   Basically, it is a bus of devices, that could act more or less
+   as a complete entity (UCC, USB etc ). All of them should be siblings on
+   the "root" qe node, using the common properties from there.
+   The description below applies to the the qe of MPC8360 and
+   more nodes and properties would be extended in the future.
+
