| 14 | This adds the CPUFreq driver for the Samsung S3C2416 and |
| 15 | S3C2450 SoC. The S3C2416 supports changing the rate of the |
| 16 | armdiv clock source and also entering a so called dynamic |
| 17 | voltage scaling mode in which it is possible to reduce the |
| 18 | core voltage of the cpu. |
