Benoit

I am having a issue in converting the above phy_id conversion from 
"<&davinci_mdio>, <0>" to
"4a101000.mdio:00". Since davinci_mdio is a child node to cpsw, the 
platform device for mdio is
not created to get the mdio device name "4a101000.mdio".
Can you point me a reference to get the right implementation.
