Pull more power management updates from Rafael Wysocki: "These fix a recent regression causing kernels built with CONFIG_PM unset to crash on systems that support the Performance and Energy Bias Hint (EPB), clean up the cpufreq core and some users of transition notifiers and introduce a new power domain flag into the generic power domains framework (genpd). Specifics: - Fix recent regression causing kernels built with CONFIG_PM unset to crash on systems that support the Performance and Energy Bias Hint (EPB) by avoiding to compile the EPB-related code depending on CONFIG_PM when it is unset (Rafael Wysocki). - Clean up the transition notifier invocation code in the cpufreq core and change some users of cpufreq transition notifiers accordingly (Viresh Kumar). - Change MAINTAINERS to cover the schedutil governor as part of cpufreq (Viresh Kumar). - Simplify cpufreq_init_policy() to avoid redundant computations (Yue Hu). - Add explanatory comment to the cpufreq core (Rafael Wysocki). - Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic power domains (genpd) framework along with the first user of it (Leonard Crestez)" * tag 'pm-5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: soc: imx: gpc: Use GENPD_FLAG_RPM_ALWAYS_ON for ERR009619 PM / Domains: Add GENPD_FLAG_RPM_ALWAYS_ON flag cpufreq: Update MAINTAINERS to include schedutil governor cpufreq: Don't find governor for setpolicy drivers in cpufreq_init_policy() cpufreq: Explain the kobject_put() in cpufreq_policy_alloc() cpufreq: Call transition notifier only once for each policy x86: intel_epb: Take CONFIG_PM into account

Pull driver core/kobject updates from Greg KH: "Here is the "big" set of driver core patches for 5.2-rc1 There are a number of ACPI patches in here as well, as Rafael said they should go through this tree due to the driver core changes they required. They have all been acked by the ACPI developers. There are also a number of small subsystem-specific changes in here, due to some changes to the kobject core code. Those too have all been acked by the various subsystem maintainers.

PM / Domains: Allow to attach a CPU via genpd_dev_pm_attach_by_id|name()

2019-04-25T21:18:03Z

Attaching a device via genpd_dev_pm_attach_by_id|name() makes genpd allocate a virtual device that it attaches instead. This leads to a problem in case when the base device belongs to a CPU. More precisely, it means genpd_get_cpu() compares against the virtual device, thus it fails to find a matching CPU device. Address this limitation by passing the base device to genpd_get_cpu() rather than the virtual device. Moreover, to deal with detach correctly from genpd_remove_device(), store the CPU number in struct generic_pm_domain_data, so as to be able to clear the corresponding bit in the cpumask for the genpd.

PM / Domains: Search for the CPU device outside the genpd lock

2019-04-25T21:18:03Z

While attaching/detaching a device to a PM domain (genpd) with GENPD_FLAG_CPU_DOMAIN set, genpd iterates the cpu_possible_mask to check whether or not the device corresponds to a CPU. This iteration is done while holding the genpd's lock, which is unnecessary. Avoid the locking by restructuring the corresponding code a bit.

PM / Domains: Drop unused in-parameter to some genpd functions

2019-04-25T21:18:03Z

Both genpd_alloc_dev_data() and genpd_add_device(), that are internal genpd functions, allow a struct gpd_timing_data *td to be passed as an in-parameter. However, as NULL is always passed, let's just drop the in-parameter altogether. Signed-off-by: Ulf Hansson Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

PM / Domains: Use the base device for driver_deferred_probe_check_state()

2019-04-25T21:18:03Z

When genpd fails to attach a device to one of its multiple PM domains, we end up calling driver_deferred_probe_check_state() for the recently allocated virtual device. This is incorrect, as it's the base device that is being probed. Fix this by passing along the base device to __genpd_dev_pm_attach() and use that instead.
