V1: https://lkml.org/lkml/2014/6/25/152

Stephen Boyd sent few patches some time back around a new cpufreq driver for
Qualcomm's Krait SoC: https://lkml.org/lkml/2014/6/24/918.

Krait couldn't use existing cpufreq-cpu0 driver as it doesn't have support for
SoC's with multiple clusters or SoC's which don't share clock line across all
CPUs.

This patchset is all about extending support beyond CPU0. It can be used for
platforms like Krait or ARM big LITTLE architecture now.

First two patches add helper routine for of and clk layer, which would be used
by later patches.

Third one adds space for driver specific data in 'struct cpufreq_policy' and
later ones migrate cpufreq-cpu0 to cpufreq-generic, i.e. can be used for SoCs
which don't share clock lines across all CPUs.

@Stephen: I haven't added your Tested-by as there were few modifications since
the time you tested it last.

Pushed here:
Rebased over v3.16-rc3:
git://git.linaro.org/people/viresh.kumar/linux.git cpufreq/cpu0-krait-v2

For guys looking to test on exynos, rebased over linux-next + some patches from
Thomas Abraham to use cpufreq-cpu0 for exynos:
