This patch provides initial support for CPU frequency scaling on the Samsung S3C ARM processors. Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Use the regulator framework to provide optional support for DVFS in the S3C cpufreq driver. When a software controllable regulator is configured the driver will use it to lower the supply voltage when running at a lower frequency, giving improved power savings. When regulator support is disabled or no regulator can be obtained for VDDARM the driver will fall back to scaling only the frequency.
