Merge tag 'pm-part2-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These are mostly fixes and cleanups and removal of the no longer needed at32ap-cpufreq driver. Specifics: - Drop the at32ap-cpufreq driver which is useless after the removal of the corresponding arch (Corentin LABBE). - Fix a regression from the 4.14 cycle in the APM idle driver by making it initialize the polling state properly (Rafael Wysocki). - Fix a crash on failing system suspend due to a missing check in the cpufreq core (Bo Yan). - Make the intel_pstate driver initialize the hardware-managed P-state control (HWP) feature on CPU0 upon resume from system suspend if HWP had been enabled before the system was suspended (Chen Yu). - Fix up the SCPI cpufreq driver after recent changes (Sudeep Holla, Wei Yongjun). - Avoid pointer subtractions during frequency table walks in cpufreq (Dominik Brodowski). - Avoid the check for ProcFeedback in ST/CZ in the cpufreq driver for AMD processors and add a MODULE_ALIAS for cpufreq on ARM IMX (Akshu Agrawal, Nicolas Chauvet). - Fix the prototype of swsusp_arch_resume() on x86 (Arnd Bergmann). - Fix up the parsing of power domains DT data (Ulf Hansson)" * tag 'pm-part2-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: arm: imx: Add MODULE_ALIAS for cpufreq cpufreq: Add and use cpufreq_for_each_{valid_,}entry_idx() cpufreq: intel_pstate: Enable HWP during system resume on CPU0 cpufreq: scpi: fix error return code in scpi_cpufreq_init() x86: hibernate: fix swsusp_arch_resume() prototype PM / domains: Fix up domain-idle-states OF parsing cpufreq: scpi: fix static checker warning cdev isn't an ERR_PTR cpufreq: remove at32ap-cpufreq cpufreq: AMD: Ignore the check for ProcFeedback in ST/CZ x86: PM: Make APM idle driver initialize polling state cpufreq: Skip cpufreq resume if it's not suspended
