Pull power management fixes from Rafael Wysocki: "These fix issues in two cpufreq drivers, in the AMD P-state driver and in the power-capping DTPM framework. Specifics: - Fix the AMD P-state driver's EPP sysfs interface in the cases when the performance governor is in use (Ayush Jain) - Make the ->fast_switch() callback in the AMD P-state driver return the target frequency as expected (Gautham R. Shenoy) - Allow user space to control the range of frequencies to use via scaling_min_freq and scaling_max_freq when AMD P-state driver is in use (Wyes Karny) - Prevent power domains needed for wakeup signaling from being turned off during system suspend on Qualcomm systems and prevent performance states votes from runtime-suspended devices from being lost across a system suspend-resume cycle in qcom-cpufreq-nvmem (Stephan Gerhold) - Fix disabling the 792 Mhz OPP in the imx6q cpufreq driver for the i.MX6ULL types that can run at that frequency (Christoph Niedermaier) - Eliminate unnecessary and harmful conversions to uW from the DTPM (dynamic thermal and power management) framework (Lukasz Luba)" * tag 'pm-6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq/amd-pstate: Only print supported EPP values for performance governor cpufreq/amd-pstate: Fix scaling_min_freq and scaling_max_freq update powercap: DTPM: Fix unneeded conversions to micro-Watts cpufreq/amd-pstate: Fix the return value of amd_pstate_fast_switch() pmdomain: qcom: rpmpd: Set GENPD_FLAG_ACTIVE_WAKEUP cpufreq: qcom-nvmem: Preserve PM domain votes in system suspend cpufreq: qcom-nvmem: Enable virtual power domain devices cpufreq: imx6q: Don't disable 792 Mhz OPP unnecessarily

pmdomain: arm: Avoid polling for scmi_perf_domain

2023-11-27T15:28:20Z

It was a mistake to prefer polling based mode when setting a performance level for a domain. Let's instead rely on the protocol to decide what is best and thus avoid polling when possible.

pmdomain: qcom: rpmpd: Set GENPD_FLAG_ACTIVE_WAKEUP

2023-11-23T07:38:01Z

Set GENPD_FLAG_ACTIVE_WAKEUP for all RPM power domains so that power domains necessary for wakeup/"awake path" devices are kept on across suspend. This is needed for example for the *_AO ("active-only") variants of the RPMPDs used by the CPU. Those should maintain their votes also across system suspend to ensure the CPU can keep running for the whole suspend process (ending in a firmware call). When the RPM firmware detects that the CPUs are in a deep idle state it will drop those votes automatically. Signed-off-by: Stephan Gerhold Reviewed-by: Ulf Hansson Signed-off-by: Viresh Kumar

Pull SoC driver updates from Arnd Bergmann: "The highlights for the driver support this time are - Qualcomm platforms gain support for the Qualcomm Secure Execution Environment firmware interface to access EFI variables on certain devices, and new features for multiple platform and firmware drivers. - Arm FF-A firmware support gains support for v1.1 specification features, in particular notification and memory transaction descriptor changes. - SCMI firmware support now support v3.2 features for clock and DVFS configuration and a new transport for Qualcomm platforms. - Minor cleanups and bugfixes are added to pretty much all the active platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and more.

pmdomain: imx: Make imx pgc power domain also set the fwnode

2023-10-26T13:55:05Z

Currently, The imx pgc power domain doesn't set the fwnode pointer, which results in supply regulator device can't get consumer imx pgc power domain device from fwnode when creating a link. This causes the driver core to instead try to create a link between the parent gpc device of imx pgc power domain device and supply regulator device. However, at this point, the gpc device has already been bound, and the link creation will fail. So adding the fwnode pointer to the imx pgc power domain device will fix this issue.
