  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.00 ms.
  hardware limits: 217 MHz - 1.73 GHz
  available frequency steps: 217 MHz, 433 MHz, 650 MHz, 867 MHz, 1.08 GHz, 1.30 GHz, 1.52 GHz, 1.73 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 217 MHz and 1.73 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 1.73 GHz.
