Merge tag 'pm-5.9-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These are mostly ARM cpufreq driver updates plus a cpufreq core cleanup, an ARM-wide change to make schedutil the default scaling governor, an intel_pstate driver fix and some runtime PM changes regarding kerneldoc comments. Specifics: - Add adaptive voltage scaling (AVS) support to the brcmstb cpufreq driver and clean it up (Florian Fainelli, Markus Mayer). - Add a new Tegra cpufreq driver and clean up the existing one (Jon Hunter, Sumit Gupta). - Add bandwidth level support to the Qcom cpufreq driver along with OPP changes (Sibi Sankar). - Clean up the sti, cpufreq-dt, ap806, CPPC cpufreq drivers (Viresh Kumar, Lee Jones, Ivan Kokshaysky, Sven Auhagen, Xin Hao). - Make schedutil the default governor for ARM (Valentin Schneider). - Fix dependency issues for the imx cpufreq driver (Walter Lozano). - Clean up cached_resolved_idx handlihng in the cpufreq core (Viresh Kumar). - Fix the intel_pstate driver to use the correct maximum frequency value when MSR_TURBO_RATIO_LIMIT is 0 (Srinivas Pandruvada). - Provide kenrneldoc comments for multiple runtime PM helpers and improve the pm_runtime_get_if_active() kerneldoc (Rafael Wysocki)" * tag 'pm-5.9-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (22 commits) cpufreq: intel_pstate: Fix cpuinfo_max_freq when MSR_TURBO_RATIO_LIMIT is 0 PM: runtime: Improve kerneldoc of pm_runtime_get_if_active() PM: runtime: Add kerneldoc comments to multiple helpers cpufreq: make schedutil the default for arm and arm64 cpufreq: cached_resolved_idx can not be negative cpufreq: Add Tegra194 cpufreq driver dt-bindings: arm: Add NVIDIA Tegra194 CPU Complex binding cpufreq: imx: Select NVMEM_IMX_OCOTP cpufreq: sti-cpufreq: Fix some formatting and misspelling issues cpufreq: tegra186: Simplify probe return path cpufreq: CPPC: Reuse caps variable in few routines cpufreq: ap806: fix cpufreq driver needs ap cpu clk cpufreq: cppc: Reorder code and remove apply_hisi_workaround variable cpufreq: dt: fix oops on armada37xx cpufreq: brcmstb-avs-cpufreq: send S2_ENTER / S2_EXIT commands to AVS cpufreq: brcmstb-avs-cpufreq: Support polling AVS firmware cpufreq: brcmstb-avs-cpufreq: more flexible interface for __issue_avs_command() cpufreq: qcom: Disable fast switch when scaling DDR/L3 cpufreq: qcom: Update the bandwidth levels on frequency change OPP: Add and export helper to set bandwidth ...
