- depends on CPU_S3C2416
- help
- This adds the CPUFreq driver for the Samsung S3C2416 and
- S3C2450 SoC. The S3C2416 supports changing the rate of the
- armdiv clock source and also entering a so called dynamic
- voltage scaling mode in which it is possible to reduce the
- core voltage of the cpu.
- If in doubt, say N.

- depends on ARM_S3C2416_CPUFREQ && REGULATOR && EXPERIMENTAL
- help
- Enable CPU voltage scaling when entering the dvs mode.
- It uses information gathered through existing hardware and
- tests but not documented in any datasheet.
- If in doubt, say N.
