Do you mean operating-points, or something else? Different SBCs will
probably require different combinations of operating points just for
safety's sake, because they have different regulators and [some have
botched] thermal designs, so it might make sense to customize it for
differnt boards, and I don't feel adventurous enough setting it for all
H3 boards out there.

Or is this comment related to the missing cpu clock rate message I see
on every boot?

[    0.058912] /cpus/cpu@0 missing clock-frequency property
