    Properties for fsl,cpm2-mdio-bitbang:
-   fsl,mdio-pin : pin of port C controlling mdio data
-   fsl,mdc-pin : pin of port C controlling mdio clock
+   The first reg resource is the I/O port register block on which MDIO
+   resides.  The second reg resource is the I/O port register block on

+   both MDIO and MDC.
