[PATCH v3 0/5] powernv: Enable Dynamic Frequency

[Gautham R. Shenoy]

From: "Gautham R. Shenoy" <ego at linux.vnet.ibm.com>

Hi,

This is the v3 of the consolidated patchset consisting
patches for enabling cpufreq on IBM POWERNV platforms
along with some enhancements. I have incorporated the review 
for v2 (which can be found at [1]).

- 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 changes from from v2:
  - Updated the changelog for "powernv: cpufreq driver for powernv platform"
    to record the fact that policy->cpus must be populated with a sibling mask
    that includes even the offlined siblings.

  - Dropped the patch named 
    "powernv:cpufreq: Create a powernv_cpu_to_core_mask() helper"
     since the driver->get() method can use cpu_sibling_mask().
  
  -  Updated "powernv:cpufreq: Implement the driver->get() method" to 
     use cpu_sibling_mask() in powernv_cpufreq_get()

The patchset is based against commit 4907cdca7210c5895311bddcf05a4c85b67d8566
of the mainline tree.
