This and it also provides a reg space where we can get/set the performance state.

I think yes we can make it work through that as well, but I am not sure if we will be able to use required-opp n stuff here as the DT doesn't have the OPP table for the CPUs.
The CPU's freq table is generated at runtime, see drivers/cpufreq/mediatek-cpufreq-hw.c for example.
