26 help
27 This adds the CPUFreq driver for the Samsung S3C2416 and
28 S3C2450 SoC. The S3C2416 supports changing the rate of the
29 armdiv clock source and also entering a so called dynamic
30 voltage scaling mode in which it is possible to reduce the
31 core voltage of the cpu.

33 If in doubt, say N.
