2ff8fe13ac cpufreq: qcom-cpufreq-nvmem: dev_pm_opp_put_*() accepts NULL argument
The dev_pm_opp_put_*() APIs now accepts a NULL opp_table pointer and so
there is no need for us to carry the extra checks. Drop them.

a5a6031663 cpufreq: qcom: Add missing MODULE_DEVICE_TABLE
This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this cpufreq driver when it is
compiled as an external module.

2dea651680 cpufreq: qcom: fix wrong compatible binding
Binding in Documentation is still "operating-points-v2-kryo-cpu".
Restore the old binding to fix the compatibility problem.

a8811ec764 cpufreq: qcom: Add support for krait based socs
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.

1cb8339ca2 cpufreq: qcom: Add support for qcs404 on nvmem driver
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.

57f2f8b4aa cpufreq: qcom: Refactor the driver to make it easier to extend
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.

7d12709544 cpufreq: qcom: Re-organise kryo cpufreq to use it for other nvmem based qcom 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.
