As you said in a previous patch, VSC7385 is a switch, not a PHY.

Could you keep the indentation level of this include the same as the others?

I don't understand why you're doing it like this (i.e. specifying the
label here, and using it in pq3-etsec2-grp2-0.dtsi, vs just specifying
the full path in pq3-etsec2-grp2-0.dtsi).

I'm pretty sure the PTP clock is not needed in U-Boot? Doesn't
checkpatch give warnings about undocumented compatible string?

You could have labeled the MDIO buses here, and just refer to the
label in the board dtsi files. I'm not sure but you may need to use
#include instead of /include/ for that.

I don't think this is needed.

What do these numbers represent?
I'm not sure it is in the best interest of maintaining this driver to
import so many DT bindings from Linux which are unused. It is highly
unlikely that anyone will make use of them in the future.
