The DP83TD510E is an ultra-low power Ethernet physical layer transceiver
that supports 10M single pair cable.

The device supports both 2.4-V p2p and 1-V p2p output voltage as defined
by IEEE 802.3cg 10Base-T1L specfications. These modes can be forced via
the device tree or the device is defaulted to auto negotiation to
determine the proper p2p voltage.

I did not see this warning. Did you use W=1?

Also this:

WARNING: ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP
#429: FILE: drivers/net/phy/dp83td510.c:371:

Same with these warnings how where they reproduced?

#580: FILE: drivers/net/phy/dp83td510.c:522:

And please try to wrap the code on 80 chars on the non trivial lines:

What is the LoC limit for networking just for my clarification and I 
will align with that.

I know some maintainers like to keep the 80 LoC and some allow a longer 
line.
