  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.
