   5        default m
   6        help
   7          This adds the cpufreq driver for Cell BE processors.
   8          For details, take a look at <file:Documentation/cpu-freq/>.
   9          If you don't have such processor, say N

  13        depends on CPU_FREQ_CBE
  14        default n
  15        help
  16          Select this, if you want to use the PMI interface to switch
  17          frequencies. Using PMI, the processor will not only be able to run at
  18          lower speed, but also at lower core voltage.

  27config CPU_FREQ_PMAC
  28        bool "Support for Apple PowerBooks"
  29        depends on ADB_PMU && PPC32
  30        help
  31          This adds support for frequency switching on Apple PowerBooks,
  32          this currently includes some models of iBook & Titanium
  33          PowerBook.

  37        depends on PPC_PMAC && PPC64
  38        help
  39          This adds support for frequency switching on Apple iMac G5,
  40          and some of the more recent desktop G5 machines as well.
