This is a split of APQ8064 cpufreq series, as requested by Viresh. This
series includes only opp and cpufreq parts, with the DT and soc parts
being split to a separate patchset.

Each core has independent power and frequency control. Additionally the
L2 cache is scaled to follow the CPU frequencies (failure to do so
results in strange semi-random crashes).

Core voltage is controlled through the SAW2 devices, one for each core.
The L2 has two regulators, vdd-mem and vdd-dig.

Dmitry Baryshkov (6):
  dt-bindings: opp: opp-v2-kryo-cpu: support Qualcomm Krait SoCs
  cpufreq: qcom-nvmem: create L2 cache device
  cpufreq: qcom-nvmem: also accept operating-points-v2-krait-cpu
  cpufreq: qcom-nvmem: drop pvs_ver for format a fuses
  cpufreq: qcom-nvmem: provide separate configuration data for apq8064
  cpufreq: qcom-nvmem: enable core voltage scaling for MSM8960
