This adds the cpufreq driver for Cell BE processors.

For details, take a look at <file:Documentation/cpu-freq/>.

If you don't have such processor, say N

Select this, if you want to use the PMI interface to switch
|
|
|
|
|
frequencies. Using PMI, the processor will not only be able to run at
|
|
|
|
|
lower speed, but also at lower core voltage.
