+-----------------------
+In addition to the required compatible-, reg- and interrupt-properites, you can
+also specify which clock source shall be used for the controller:
+
+- fsl,mscan-clock-source- a string describing the clock source. Valid values
+                          are:  "ip" for ip bus clock
+                                "ref" for reference clock (XTAL)
+                          "ref" is default in case this property is not
+                          present.
