Cover letter [PATCH 00/16] cpufreq: create & use cpufreq_generic_get() routine

CPUFreq drivers that use clock frameworks interface,i.e. clk_get_rate(), to get CPUs clk rate, has similar sort of code used for most of them.

This patchset adds a generic ->get() which will do the same thing for them. All those drivers are required to now is to set .get to cpufreq_generic_get() and set their clk pointer in policy->clk during ->init().

Later part of this patchset fixes 17 drivers with this change.

That's part 7 of my generic cleanups for CPUFreq core, first six are here:

1: cpufreq: Introduce cpufreq_table_validate_and_show()
https://lkml.org/lkml/2013/8/8/263

2: cpufreq: define generic routines for cpufreq drivers
https://lkml.org/lkml/2013/8/10/48

3. CPUFreq: Implement light weight ->target(): for 3.13
https://lkml.org/lkml/2013/8/13/349

4. CPUFreq: set policy->cur in cpufreq core instead of drivers
https://lkml.org/lkml/2013/8/14/288

5. CPUFreq: Move freq change notifications out of drivers
https://lkml.org/lkml/2013/8/15/506

6. cpufreq: create & use cpufreq_generic_init() routine
http://lkml.org/lkml/2013/8/21/352

All these are pushed here:
