Hello,

As is in the vanilla kernel there is no cpufreq support on the Orange Pi Prime. 
The CPU is stuck at some base frequency and the performance is low.
The included one-line patch makes it work, the frequency can be queried and auto-scales with load, the peak performance is also improved.

Thanks
