This series converts the DPAA driver to phylink. Additionally, it also adds a serdes driver to allow for dynamic reconfiguration between 1g and 10g interfaces (such as in an SFP+ slot). These changes are submitted together for this RFC, but they will eventually be submitted separately to the appropriate subsystem maintainers. Only the mEMAC driver has gotten the phylink treatment for this RFC. I would appreciate any help towards converting/testing the 10GEC and dTSEC drivers. I don't have any boards with those MACs, so a large conversion like this has a high risk of breakage. I have tried to maintain backwards compatibility with existing device trees whereever possible. However, one area where I was unable to achieve this was with QSGMII. Please refer to patch 2 for details. The serdes driver is mostly functional (but not quite, see patch 25). However, I am not quite sure about the implementation details. I have made a fairly extensive commentary on the driver in patch 1, so hopefully that can provide some context. This series only adds support for the LS1046ARDB SerDes, but it should be fairly straightforward to add support for other SoCs and boards. Patches 26-27 should show the typical steps. Most of this series can be applied as-is. In particular, patches 4-21 are essentially cleanups which stand on their own merits. Patches 4-8 were first submitted as [1].
