| tristate "CBE frequency scaling" |
| depends on CBE_RAS && PPC_CELL |
| default m |
| help |
| 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 |

| config CPU_FREQ_CBE_PMI |
| bool "CBE frequency scaling using PMI interface" |
| depends on CPU_FREQ_CBE |
| default n |
| help |
| 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. |
