58 controllers found in the ASPEED AST2600 SoC. This is a driver for the
59 third revision of the ASPEED MDIO register interface - the first two
60 revisions are the "old" and "new" interfaces found in the AST2400 and
61 AST2500, embedded in the MAC. For legacy reasons, FTGMAC100 driver
62 continues to drive the embedded MDIO controller for the AST2400 and
