[PATCH 0/4] powernv:cpufreq: Export nominal and current frequency via sysfs

[Gautham R. Shenoy]

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

Hi,

On IBM POWERNV platforms[1], presently we do not report the current
operating frequency of the processor through the sysfs interface
"cpuinfo_cur_freq" since the cpu frequency driver[1] has not
implemented the ->get(unsigned int cpu) method. Fix this by
implementing the ->get(unsigned int cpu) method which will report the
frequency corresponding to the pstate_id on PMSR on "cpu".

Also, export the nominal frequency of the processor through the sysfs
interface "cpuinfo_nominal_freq" by defining it as a driver attribute.

The patch series depends on the cpu-frequency driver patch-series[1].
