Would you mind forwarding me the changes you actually made so I can
integrate them into the version I have (which is structured quite
differently from - what I assume - is a much older version of my
patches please?

The PTP IP is re-used not only in Marvell PHY drivers but also their
DSA drivers, and having it all in drivers/net/phy/ as this version
has does not make sense.

Thanks.
