  CPUs which need to switch frequency at the same time: 0

  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, performance
  current policy: frequency should be within 217 MHz and 1.73 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 217 MHz (asserted by call to hardware).
