52 This module provides a driver for the independent MDIO bus
53 controllers found in the ASPEED AST2600 SoC. This is a driver for the
54 third revision of the ASPEED MDIO register interface - the first two
55 revisions are the "old" and "new" interfaces found in the AST2400 and
56 AST2500, embedded in the MAC. For legacy reasons, FTGMAC100 driver
57 continues to drive the embedded MDIO controller for the AST2400 and
