9 This adds the CPUFreq driver for the Samsung S3C2416 and
10 S3C2450 SoC. The S3C2416 supports changing the rate of the
11 armdiv clock source and also entering a so called dynamic
12 voltage scaling mode in which it is possible to reduce the
13 core voltage of the cpu.
14
15 If in doubt, say N.

21 Enable CPU voltage scaling when entering the dvs mode.
22 It uses information gathered through existing hardware and
23 tests but not documented in any datasheet.
