+fsl,mpc5200-mscan nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, 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.

+fsl,mpc5121-mscan nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source and divider 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
+                                "sys" for system clock
+                           If this property is not present, an optimal CAN
+                           clock source and frequency based on the system
+                           clock will be selected. If this is not possible,
+                           the reference clock will be used.
+
+- fsl,mscan-clock-divider: for the reference and system clock, an additional
+                           clock divider can be specified. By default, a
+                           value of 1 is used.
+
+Note that the MPC5121 Rev. 1 processor is not supported.

+                compatible = "fsl,mpc5121-mscan";
+                interrupts = <12 0x8>;
