+-----------------------
+In addition to the required compatible-, reg- and interrupt-properites, you can
+also specify which clock shall be used for the bus:
+
+- fsl,mscan-clk-src     - a string describing the clock source. Valid values
+                          are "ip" for IP_CLK and "sys" for SYS_XTAL.
+                          "sys" is the default in case the property is not
+                          present.
