Dylan Hung abc75897ca ARM: dts: ast2600: Add MDIO devices
There are 4 MDIO bus controllers in AST2600 SOC.  Each of them can
connect to one or more PHY chips and is flexible to work with the 4 MAC
devices in AST2600.  On AST2600 EVB, MDIO 0,1,2,3 connect to the PHY
chips used by MAC 0,1,2,3 respectively.
