I'm not sure if that would be flexible enough to meet the requirement:
power for each OPP might be different in one board vs. other board.

Don't DT files overload values from board files all the time ? Why wouldn't the
same apply for OPP table as well ?

In that SoC and family of the boards, there are no such examples.
It used to be popular in arm32 boards, but I'm not sure nowadays.


AFAIK the OPP definition is more SoC specific.

This isn't about OPP definition as well, but just that if DT allows you to
override or not. I think it will.


Redefining the whole OPP table, when the freq, voltage, interconnect,
and other old entries don't change isn't too messy?

As I said, I would prefer something lightweight, not redefining all
stuff from OPP in every board file.
