2020-05-04cpufreq: qcom: fix wrong compatible bindingAnsuel Smith
Binding in Documentation is still "operating-points-v2-kryo-cpu". Restore the old binding to fix the compatibility problem. Fixes: a8811ec764f9 ("cpufreq: qcom: Add support for krait based socs") Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
2020-03-20cpufreq: qcom: Add support for krait based socsAnsuel Smith
In Certain QCOM SoCs like ipq8064, apq8064, msm8960, msm8974 that has KRAIT processors the voltage/current value of each OPP varies based on the silicon variant in use. The required OPP related data is determined based on the efuse value. This is similar to the existing code for kryo cores. So adding support for krait cores here.

2019-09-03cpufreq: qcom: Add support for qcs404 on nvmem driverNiklas Cassel
Add support for qcs404 on nvmem driver. The qcs404 SoC has support for Core Power Reduction (CPR), which is implemented as a power domain provider, therefore add optional support in this driver to attach to a genpd power domain.

2019-09-03cpufreq: qcom: Refactor the driver to make it easier to extendNiklas Cassel
Refactor the driver to make it easier to extend in a later commit. Create a driver struct to collect all common resources, in order to make it easier to free up all common resources. Create a driver match_data struct to make it easier to extend the driver with support for new features that might only be supported on certain SoCs.

2019-09-03cpufreq: qcom: Re-organise kryo cpufreq to use it for other nvmem based qcom ↵Sricharan R
socs The kryo cpufreq driver reads the nvmem cell and uses that data to populate the opps. There are other qcom cpufreq socs like krait which does similar thing. Except for the interpretation of the read data, rest of the driver is same for both the cases. So pull the common things out for reuse.
