Then maybe you shouldn't be trying to make OPP table work here. At that point you just need a table of voltage(s) per performance state?

Why not reference the OPP entries from the domain:
performance-states = <&opp1>, <&opp2>;
Just thinking out loud, not saying that is what you should do. The continual evolution of power (management) domain, idle state, and OPP bindings is getting tiring.
