We also have currently for example sm7325=sc7280=qcm6490, would that
fall into this category as well for you, or are they more different?

But do you think it's worth trying to also change existing platforms
like that? We also have basically the same list in
drivers/cpufreq/cpufreq-dt-platdev.c where we have both sm6350 and
sm7225 right now.
