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.

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.
