2019-02-08cpufreq: qcom-hw: Register an Energy ModelMatthias Kaehlcke1-0/+2
Try and register an Energy Model from qcom-cpufreq-hw to allow interested sub-systems like the task scheduler to use the provided information. Signed-off-by: Matthias Kaehlcke <mka@chromium.org> [ Viresh: Rebased over cpufreq related changes ] Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
2019-02-08cpufreq: qcom: Read voltage LUT and populate OPPTaniya Das1-9/+37
Add support to read the voltage look up table and populate OPP for all corresponding CPUS for consumers like the energy model could use the frequency and voltage from the OPP tables. Also update the logic to not add duplicate OPPs.

2019-02-08cpufreq: qcom-hw: Move to device_initcallAmit Kucheria1-1/+1
subsys_initcall causes problems registering the driver as a thermal cooling device. If "faster boot" is the main reason for doing subsys_initcall, this should be handled in the bootloader or another boot constraint framework.

2019-01-30cpufreq: qcom-hw: Register as a cpufreq cooling deviceAmit Kucheria1-1/+2
Add the CPUFREQ_IS_COOLING_DEV flag to allow the cpufreq core to auto-register the driver as a cooling device.

2018-12-18cpufreq: qcom-hw: Add support for QCOM cpufreq HW driverTaniya Das1-0/+308
The CPUfreq HW present in some QCOM chipsets offloads the steps necessary for changing the frequency of CPUs. The driver implements the cpufreq driver interface for this hardware engine.
