This patch set starts the separation of C22 and C45 MDIO bus transactions at the API level to the MDIO Bus drivers. C45 read and write ops are added to the MDIO bus driver structure, and the MDIO core will try to use these ops if requested to perform a C45 transfer. If not available a fallback to the older API is made, to allow backwards compatibility until all drivers are converted. A few drivers are then converted to this new API. The core DSA patch was dropped for now as there is still an ongoing discussion. It will be picked up in a later series again. To: Heiner Kallweit To: Russell King To: "David S.
