   4 Subject: net: dsa: realtek: get internal MDIO node by name
   5
   6 The binding docs requires for SMI-connected devices that the switch
   7 must have a child node named "mdio" and with a compatible string of
   8 "realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding
   9 docs only requires a child node named "mdio".
  10
  11 This patch changes the driver to use the common denominator for both
  12 interfaces, looking for the MDIO node by name, ignoring the compatible
  13 string.
