| 28 | This option adds a CPUFreq driver for loongson processors which |
| 29 | support software configurable cpu frequency. |
| 30 | |
| 31 | Loongson2F and it's successors support this feature. |
| 32 | |
| 33 | For details, take a look at <file:Documentation/cpu-freq/>. |
| 34 | |
| 35 | If in doubt, say N. |
