| 2 | tristate "CBE frequency scaling" |
| 3 | depends on CBE_RAS && PPC_CELL |
| 4 | default m |
| 5 | help |
| 6 | This adds the cpufreq driver for Cell BE processors. |
| 7 | For details, take a look at <file:Documentation/cpu-freq/>. |
| 8 | If you don't have such processor, say N |

| 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. |
