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