  10. config CPU_FREQ_CBE_PMI
  11. bool "CBE frequency scaling using PMI interface"
  12. depends on CPU_FREQ_CBE
  13. default n
  14. help
  15. Select this, if you want to use the PMI interface to switch
  16. frequencies. Using PMI, the processor will not only be able to run at
  17. lower speed, but also at lower core voltage.
