This is the v2 of the consolidated patchset consisting
patches for enabling cpufreq on IBM POWERNV platforms
along with some enhancements. 

The v1 of these patches have been previously 
submitted on linuxppc-dev [1][2].

- This patchset contains code for the platform driver to support CPU
  frequency scaling on IBM POWERNV platforms.

- In addition to the standard control and status files exposed by the
  cpufreq core, the patchset exposes the nominal frequency through the
  file named "cpuinfo_nominal_freq".

The patchset is based against commit c3bebc71c4bcdafa24b506adf0c1de3c1f77e2e0
of the mainline tree.
