Hi Stefan,
I will need to resend this patch (V3 3/4).
Ok. Please add the patch version and history back into the patches
next time again.
Also, when re-sending please include the already collected tags into
the patches (Reviewed-by, Acked-by etc), if the patch has not changed
too much.
Thanks,
Stefan
Thanks,
Stefan

In DM Ethernet, the old "egiga0" name is no longer valid, so
replace it
with Ethernet PHY name from device tree. Also, Ethernet PHY address
is available so read it from device tree.
