cpufreq: remove unused arm_big_little_dt driver

2018-10-25T16:39:02+00:00

Most of the ARM platforms used cpufreq-dt driver irrespective of whether it's big-little(HMP) or SMP system. This arm_big_little_dt is not used actively at all. So let's remove the driver, so that it need not be maintained. Signed-off-by: Sudeep Holla Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

cpufreq: exynos: Remove support for Exynos5440

2018-07-17T17:55:51+00:00

The Exynos5440 is not actively developed, there are no development boards available and probably there are no real products with it. Remove wide-tree support for Exynos5440. Signed-off-by: Krzysztof Kozlowski Acked-by: Viresh Kumar Reviewed-by: Chanwoo Choi Reviewed-by: Rob Herring

cpufreq: Add Kryo CPU scaling driver

2018-05-30T10:53:11+00:00

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.

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2018-04-06T04:29:35+00:00

Pull ARM SoC driver updates from Arnd Bergmann: "The main addition this time around is the new ARM "SCMI" framework, which is the latest in a series of standards coming from ARM to do power management in a platform independent way. This has been through many review cycles, and it relies on a rather interesting way of using the mailbox subsystem, but in the end I agreed that Sudeep's version was the best we could do after all. Other changes include: - the ARM CCN driver is moved out of drivers/bus into drivers/perf, which makes more sense. Similarly, the performance monitoring portion of the CCI driver are moved the same way and cleaned up a little more. - a series of updates to the SCPI framework - support for the Mediatek mt7623a SoC in drivers/soc - support for additional NVIDIA Tegra hardware in drivers/soc - a new reset driver for Socionext Uniphier - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and drivers/firmware and drivers/reset across platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (87 commits) reset: uniphier: add ethernet reset control support for PXs3 reset: stm32mp1: Enable stm32mp1 reset driver dt-bindings: reset: add STM32MP1 resets reset: uniphier: add Pro4/Pro5/PXs2 audio systems reset control reset: imx7: add 'depends on HAS_IOMEM' to fix unmet dependency reset: modify the way reset lookup works for board files reset: add support for non-DT systems clk: scmi: use devm_of_clk_add_hw_provider() API and drop scmi_clocks_remove firmware: arm_scmi: prevent accessing rate_discrete uninitialized hwmon: (scmi) return -EINVAL when sensor information is unavailable amlogic: meson-gx-socinfo: Update soc ids soc/tegra: pmc: Use the new reset APIs to manage reset controllers soc: mediatek: update power domain data of MT2712 dt-bindings: soc: update MT2712 power dt-bindings cpufreq: scmi: add thermal dependency soc: mediatek: fix the mistaken pointer accessed when subdomains are added soc: mediatek: add SCPSYS power domain driver for MediaTek MT7623A SoC soc: mediatek: avoid hardcoded value with bus_prot_mask dt-bindings: soc: add header files required for MT7623A SCPSYS dt-binding dt-bindings: soc: add SCPSYS binding for MT7623 and MT7623A SoC ...

cpufreq: add support for CPU DVFS based on SCMI message protocol

2018-02-28T16:37:57+00:00

On some ARM based systems, a separate Cortex-M based System Control Processor(SCP) provides the overall power, clock, reset and system control including CPU DVFS. SCMI Message Protocol is used to communicate with the SCP. This patch adds a cpufreq driver for such systems using SCMI interface to drive CPU DVFS. Cc: linux-pm@vger.kernel.org Acked-by: Rafael J.

cpufreq: Add DVFS support for Armada 37xx

2017-12-16T16:11:43+00:00

This patch adds DVFS support for the Armada 37xx SoCs There are up to four CPU frequency loads for Armada 37xx controlled by the hardware. This driver associates the CPU load level to a frequency, then the hardware will switch while selecting a load level. The hardware also can associate a voltage for each level (AVS support) but it is not yet supported Tested-by: Andre Heider Acked-by: Viresh Kumar Signed-off-by: Gregory CLEMENT Signed-off-by: Rafael J.
