2018-05-30cpufreq: Add Kryo CPU scaling driverIlia Lin1-0/+3
In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors, the CPU frequency subset and voltage value of each OPP varies based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables defines the voltage and frequency value based on the msm-id in SMEM and speedbin blown in the efuse combination. The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC to provide the OPP framework with required information. This is used to determine the voltage and frequency value for each OPP of operating-points-v2 table when it is parsed by the OPP framework.

2017-09-26cpufreq: dt: Fix sysfs duplicate filename creation for platform-deviceSuniel Mahesh1-0/+4
ti-cpufreq and cpufreq-dt-platdev drivers are registering platform-device with same name "cpufreq-dt" using platform_device_register_*() routines. This is leading to build warnings appended below. Providing hardware information to OPP framework along with the platform- device creation should be done by ti-cpufreq driver before cpufreq-dt driver comes into place. This patch add's TI am33xx, am43 and dra7 platforms (which use opp-v2 property) to the blacklist of devices in cpufreq-dt-platform driver to avoid creating platform-device twice and remove build warnings.

Commit edeec420de24 (cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2) missed adding few platforms to the blacklist which create the cpufreq-dt device from their own drivers, after some dependencies are sorted out. And for those platforms, both the platform specific driver and the cpufreq-dt-platdev driver try to create the cpufreq-dt device now. Fix that by including those platforms in the blacklist. This doesn't include the TI platforms, for which there is a separate patch.

2017-08-25cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2Viresh Kumar1-5/+40
The initial idea of creating the cpufreq-dt-platdev.c file was to keep a list of platforms that use the "operating-points" (V1) bindings and create cpufreq device for them only, as we weren't sure which platforms would want the device to get created automatically as some had their own cpufreq drivers as well, or wanted to initialize cpufreq after doing some stuff from platform code. But that wasn't the case with platforms using "operating-points-v2" property. We wanted the device to get created automatically without the need of adding them to the whitelist. Though, we will still have some exceptions where we don't want to create the device automatically. Rename the earlier platform list as *whitelist* and create a new *blacklist* as well. The cpufreq-dt device will get created if: - The platform is there in the whitelist OR - The platform has "operating-points-v2" property in CPU0's DT node and isn't part of the blacklist .

2016-11-11cpufreq: pxa: use generic platdev driver for device-treeRobert Jarzmik1-0/+2
For device-tree based pxa25x and pxa27x platforms, cpufreq-dt driver is doing the job as well as pxa2xx-cpufreq, so add these platforms to the compatibility list. This won't work for legacy non device-tree platforms where pxa2xx-cpufreq is still required.

Now that the cpufreq-dt-platdev is used to create the cpufreq-dt platform device for all OMAP platforms and the platform code that did it before has been removed, add ti,am33xx and ti,dra7xx to the machine list in cpufreq-dt-platdev which had relied on the removed platform code to do this previously.

2016-09-13cpufreq: dt: Support governor tunables per policyViresh Kumar1-2/+5
The cpufreq-dt driver is also used for systems with multiple clock/voltage domains for CPUs, i.e. multiple cpufreq policies in a system. And in such cases the platform users may want to enable "governor tunables per policy". Support that via platform data, as not all users of the driver would want that behavior.

If of_match_node() fails, this init function bails out without calling of_node_put(). Also change of_node_put(of_root) to of_node_put(np); both of them hold the same pointer, but it seems better to call of_node_put() against the node returned by of_find_node_by_path().
