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. | |

26 | Enable CPU voltage scaling when entering the dvs mode. | |
27 | It uses information gathered through existing hardware and | |
