analyzing CPU 0:
driver: hi-cpufreq
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: 300 us.
hardware limits: 400 MHz - 2.00 GHz
available frequency steps: 400 MHz, 600 MHz, 800 MHz, 1.20 GHz, 1.60 GHz, 2.00 GHz
available cpufreq governors: interactive, conservative, ondemand, powersave, userspace, performance
current policy: frequency should be within 400 MHz and 2.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 400 MHz (asserted by call to hardware).
