| This adds the CPUFreq driver for the Samsung S3C2416 and |
| S3C2450 SoC. The S3C2416 supports changing the rate of the |
| armdiv clock source and also entering a so called dynamic |
| voltage scaling mode in which it is possible to reduce the |
| core voltage of the cpu. |
| |
| If in doubt, say N. |
