cpufreq: brcmstb-avs-cpufreq: remove development debug support

2018-06-20T19:01:24Z

[ Upstream commit ee53a65dc766384aaf1a26e3c43dd13456170b69 ] This debug code was helpful while developing the driver, but it isn't being used for anything anymore.

cpufreq: armada-37xx: driver relies on cpufreq-dt

2018-05-22T16:56:23Z

commit 0cf442c6bcf572e04f5690340d5b8e62afcee2ca upstream. Armada-37xx driver registers a cpufreq-dt driver. Not having CONFIG_CPUFREQ_DT selected leads to a silent abort during the probe. Prevent that situation by having the former depending on the latter.

cpufreq: scpi: Fix incorrect arm_big_little config dependency

2018-02-26T22:29:19Z

Commit 343a8d17fa8d (cpufreq: scpi: remove arm_big_little dependency) removed the SCPI cpufreq dependency on arm_big_little cpufreq driver. However the Kconfig entry still depends on ARM_BIG_LITTLE_CPUFREQ which is clearly wrong. This patch removes that unnecessary Kconfig dependency.

cpufreq: Add DVFS support for Armada 37xx

2017-12-16T16:11:43Z

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.

cpufreq: ARM: sort the Kconfig menu

2017-12-16T01:29:42Z

Group all the related big LITTLE configuration together and sort the other entries in alphabetic order. Also fixing tab vs space issue while mofifying these entries. Acked-by: Viresh Kumar Signed-off-by: Gregory CLEMENT Signed-off-by: Rafael J. Wysocki

cpufreq: dbx500: Delete obsolete driver

2017-08-22T13:50:02Z

We have moved the Ux500 over to use the generic DT based cpufreq driver, so delete the old custom driver. At the same time select CPUFREQ_DT from the machine's Kconfig in order to satisfy the "default ARCH_U8500" selection on the old driver.

cpufreq: dt: Don't use generic platdev driver for tango

2017-07-22T00:20:59Z

On tango platforms, firmware configures the CPU clock, and Linux is then only allowed to use the cpu_clk_divider to change the frequency. Build the OPP table dynamically at init, in order to support whatever firmware throws at us. Signed-off-by: Marc Gonzalez Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

cpufreq: mediatek: Add support of cpufreq to MT2701/MT7623 SoC

2017-07-22T00:19:37Z

MT2701/MT7623 is a 32-bit ARMv7 based quad-core (4 * Cortex-A7) with single cluster and this hardware is also compatible with the existing driver through enabling CPU frequency feature with operating-points-v2 bindings. Also, this driver actually supports all MediaTek SoCs, the Kconfig menu entry and file name itself should be updated with more generic name to drop "MT8173" Signed-off-by: Sean Wang Acked-by: Viresh Kumar Reviewed-by: Jean Delvare Signed-off-by: Rafael J.

cpufreq: dbx500: add a Kconfig symbol

2017-05-14T11:40:16Z

Moving the cooling code into the cpufreq driver caused a possible build failure when the cpu_thermal helper code is a loadable module or disabled: drivers/cpufreq/dbx500-cpufreq.o: In function `dbx500_cpufreq_ready': dbx500-cpufreq.c:(.text.dbx500_cpufreq_ready+0x4): undefined reference to `cpufreq_cooling_register' This adds the same dependency that we have in other cpufreq drivers, forcing the driver to be disabled when we can't possibly link it.

cpufreq: Add Tegra186 cpufreq driver

2017-04-19T21:23:08Z

Add a new cpufreq driver for Tegra186 (and likely later). The CPUs are organized into two clusters, Denver and A57, with two and four cores respectively. CPU frequency can be adjusted by writing the desired rate divisor and a voltage hint to a special per-core register. The frequency of each core can be set individually; however, this is just a hint as all CPUs in a cluster will run at the maximum rate of non-idle CPUs in the cluster.
