The Seville driver uses indirect MDIO access by way of
MSCC_MIIM_CMD_* macros. This is duplicate behavior of
drivers/net/mdio/mdio-mscc-miim.c, which achieves the same thing. The
main difference being that Seville uses regmap by way of the ocelot
driver, whereas mdio-mscc-miim uses __iomem. 

This patch set converts mdio-mscc-miim to regmap, exposes an API, and
hooks Seville into this common driver by way of mscc_miim_setup.

Colin Foster (3):
  net: mdio: mscc-miim: convert to a regmap implementation
  net: dsa: ocelot: seville: utilize of_mdiobus_register
  net: dsa: ocelot: felix: switch to mdio-mscc-miim driver for indirect
    mdio access
