   3 Properties:
   4 - compatible: can be one of:
   5         "hisilicon,hns-mdio"
   6         "hisilicon,mdio"
   7   "hisilicon,hns-mdio" is recommended to be used for hip05 and later SOCs,
   8   while "hisilicon,mdio" is optional for backwards compatibility only on
   9   hip04 Soc.

  19                    #size-cells = <0>;
  20                    compatible = "hisilicon,hns-mdio","hisilicon,mdio";
