  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.
