Hi!
I've recently bought a nanopi NEO2 which features an Allwinner H5. On FriendlyArm website (and on Allwinner's too) it is stated that the H5 is clocked 1.5Ghz. I need to perform some heavy job and and noticed that the cpu frequency hits, at full power, only 1Ghz. I checked using cpufreq-info and I got:
driver: cpufreq-dt
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0 1 2 3
maximum transition latency: 244 us.
