cpufreq support for omap

Registered by vishwanath sripathy on 2011-01-27

In OMAP, DVFS (dynamic voltage and frequency scaling) feature is not supported in mainline kernel. So cpufreq is not functional. Purpose of this blueprint is to track development effort for upstreaming dvfs support so that cpufreq can work seamlessly on OMAP.

We're not developing anything in the PMWG anymore for this work. We're simply taking what is available in the TI trees and packaging it for our work.
