Subject: [PATCH net-next 00/28] [RFC] net: dpaa: Convert to phylink
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].
