      Pull power management updates from Rafael Wysocki:
       "These include a rework of the main suspend-to-idle code flow (related
        to the handling of spurious wakeups), a switch over of several users
        of cpufreq notifiers to QoS-based limits, a new devfreq driver for
        Tegra20, a new cpuidle driver and governor for virtualized guests, an
        extension of the wakeup sources framework to expose wakeup sources as
        device objects in sysfs, and more.
      
        Specifics:
      
         - Rework the main suspend-to-idle control flow to avoid repeating
           "noirq" device resume and suspend operations in case of spurious
           wakeups from the ACPI EC and decouple the ACPI EC wakeups support
           from the LPS0 _DSM support (Rafael Wysocki).
      
         - Extend the wakeup sources framework to expose wakeup sources as
           device objects in sysfs (Tri Vo, Stephen Boyd).
      
         - Expose system suspend statistics in sysfs (Kalesh Singh).
      
         - Introduce a new haltpoll cpuidle driver and a new matching governor
           for virtualized guests wanting to do guest-side polling in the idle
           loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).
      
         - Fix the menu and teo cpuidle governors to allow the scheduler tick
           to be stopped if PM QoS is used to limit the CPU idle state exit
           latency in some cases (Rafael Wysocki).
      
         - Increase the resolution of the play_idle() argument to microseconds
           for more fine-grained injection of CPU idle cycles (Daniel
           Lezcano).
      
         - Switch over some users of cpuidle notifiers to the new QoS-based
           frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
           policy notifier events (Viresh Kumar).
      
         - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
      
         - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
           (Andrew-sh.Cheng, Fabien Parent).
      
         - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
           Huang).
      
         - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
      
         - Update the qcom cpufreq driver (among other things, to make it
           easier to extend and to use kryo cpufreq for other nvmem-based
           SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
           RAILLARD, Sibi Sankar, Sricharan R).
      
         - Fix assorted issues and make assorted minor improvements in the
           cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
           Gustavo Silva, Hariprasad Kelam).
      
         - Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
           Bergmann).
      
         - Add new Exynos PPMU events to devfreq events and extend that
           mechanism (Lukasz Luba).
      
         - Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
      
         - Improve devfreq documentation and governor code, fix spelling typos
           in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
           MyungJoo Ham, Gaël PORTAY).
      
         - Add regulators enable and disable to the OPP (operating performance
           points) framework (Kamil Konieczny).
      
         - Update the OPP framework to support multiple opp-suspend properties
           (Anson Huang).
      
         - Fix assorted issues and make assorted minor improvements in the OPP
           code (Niklas Cassel, Viresh Kumar, Yue Hu).
      
         - Clean up the generic power domains (genpd) framework (Ulf Hansson).
      
         - Clean up assorted pieces of power management code and documentation
           (Akinobu Mita, Amit Kucheria, Chuhong Yuan).

      Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
      
      Pull LED updates from Jacek Anaszewski:
       "In this cycle we've finally managed to contribute the patch set
        sorting out LED naming issues. Besides that there are many changes
        scattered among various LED class drivers and triggers.
      
        LED naming related improvements:
      
         - add new 'function' and 'color' fwnode properties and deprecate
           'label' property which has been frequently abused for conveying
           vendor specific names that have been available in sysfs anyway
      
         - introduce a set of standard LED_FUNCTION* definitions
      
         - introduce a set of standard LED_COLOR_ID* definitions
      
         - add a new {devm_}led_classdev_register_ext() API with the
           capability of automatic LED name composition basing on the
           properties available in the passed fwnode; the function is
           backwards compatible in a sense that it uses 'label' data, if
           present in the fwnode, for creating LED name
      
         - add tools/leds/get_led_device_info.sh script for retrieving LED
           vendor, product and bus names, if applicable; it also performs
           basic validation of an LED name
      
         - update following drivers and their DT bindings to use the new LED
           registration API:
      
              - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
                leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
      
        Other LED class improvements:
      
         - replace {devm_}led_classdev_register() macros with inlines
      
         - allow to call led_classdev_unregister() unconditionally
      
         - switch to use fwnode instead of be stuck with OF one
      
        LED triggers improvements:
      
         - led-triggers:
              - fix dereferencing of null pointer
              - fix a memory leak bug
      
         - ledtrig-gpio:
              - GPIO 0 is valid
      
        Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
        more complete driver exists, based on a generic driver for the AMD
        SOCs gpio-controller, supporting LEDs as well other devices:
      
         - drop profile field from priv data
      
         - drop iosize field from priv data
      
         - drop enum_apu_led_platform_types
      
         - drop superseeded apu2/3 led support
      
         - add pr_fmt prefix for better log output
      
         - fix error message on probing failure
      
        Other misc fixes and improvements to existing LED class drivers:
      
         - leds-ns2, leds-max77650:
              - add of_node_put() before return
      
         - leds-pwm, leds-is31fl32xx:
              - use struct_size() helper
      
         - leds-lm3697, leds-lm36274, leds-lm3532:
              - switch to use fwnode_property_count_uXX()
      
         - leds-lm3532:
              - fix brightness control for i2c mode
              - change the define for the fs current register
              - fixes for the driver for stability
              - add full scale current configuration
              - dt: Add property for full scale current.
              - avoid potentially unpaired regulator calls
              - move static keyword to the front of declarations

              - add MODULE_ALIAS()
              - Switch to fwnode property API

              - fix misuse of strlcpy
      
         - leds-netxbig:
              - add of_node_put() in netxbig_leds_get_of_pdata()
              - remove legacy board-file support
      
         - leds-is31fl319x:
              - simplify getting the adapter of a client
      
         - leds-ti-lmu-common:
              - fix coccinelle issue
              - move static keyword to the front of declaration

      Pull sound updates from Takashi Iwai:
       "As shown in diffstat and logs, it was again a busy development cycle
        at this time, too. The most significant changes are still on-going
        refactoring / modernization works for ASoC core and drivers, but there
        are lots of other changes as well. Here we go, some highlights below:
      
        ASoC:
      
         - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
           them are systematic, but also including cleanups and modernization
      
         - A bulk of updates for some ASoC platforms, Freescale, sunxi and
           Intel SST/SOF
      
         - Initial support for Sound Open Firmware on i.MX8
      
         - Removal of deprecated w90x900 and nuc900 drivers
      
         - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
           7ULP and 8MQ, Meson G12A and NXP UDA1334
      
        USB-audio:
      
         - More validations of descriptor units for hardening against bugs
           reported by fuzzers
      
         - PCM device assignment workaround for a past call-order change
      
         - Scarlett Gen2 mixer interface, a few more more quirks
      
        HD-audio:
      
         - Support for audio component with AMD/ATI and Nvidia HDMI codecs
      
         - Clean up HD-audio core and remove indirect access ops for Intel SOF
      
         - DMIC detection at probe; it would make systems automatically
           falling back to SST/SOF driver on devices that need DMIC handling.
           Needs a new Kconfig to set, and beware that it's still new and a
           bit experimental
      
        FireWire:
      
         - Lots of code refactoring and cleanups"

       "Timers and timekeeping updates:
      
         - A large overhaul of the posix CPU timer code which is a preparation
           for moving the CPU timer expiry out into task work so it can be
           properly accounted on the task/process.
      
           An update to the bogus permission checks will come later during the
           merge window as feedback was not complete before heading of for
           travel.
      
         - Switch the timerqueue code to use cached rbtrees and get rid of the
           homebrewn caching of the leftmost node.
      
         - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
           single function
      
         - Implement the separation of hrtimers to be forced to expire in hard
           interrupt context even when PREEMPT_RT is enabled and mark the
           affected timers accordingly.
      
         - Implement a mechanism for hrtimers and the timer wheel to protect
           RT against priority inversion and live lock issues when a (hr)timer
           which should be canceled is currently executing the callback.
           Instead of infinitely spinning, the task which tries to cancel the
           timer blocks on a per cpu base expiry lock which is held and
           released by the (hr)timer expiry code.
      
         - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
           resulting in faster access to timekeeping functions.
      
         - Updates to various clocksource/clockevent drivers and their device
           tree bindings.

      Pull x86 apic updates from Thomas Gleixner:
      
       - Cleanup the apic IPI implementation by removing duplicated code and
         consolidating the functions into the APIC core.
      
       - Implement a safe variant of the IPI broadcast mode. Contrary to
         earlier attempts this uses the core tracking of which CPUs have been
         brought online at least once so that a broadcast does not end up in
         some dead end in BIOS/SMM code when the CPU is still waiting for
         init. Once all CPUs have been brought up once, IPI broadcasting is
         enabled. Before that regular one by one IPIs are issued.
      
       - Drop the paravirt CR8 related functions as they have no user anymore
      
       - Initialize the APIC TPR to block interrupt 16-31 as they are reserved
         for CPU exceptions and should never be raised by any well behaving
         device.
      
       - Emit a warning when vector space exhaustion breaks the admin set
         affinity of an interrupt.
      
       - Make sure to use the NMI fallback when shutdown via reboot vector IPI
         fails. The original code had conditions which prevent the code path
         to be reached.
      
       - Annotate various APIC config variables as RO after init.
      
      [ The ipi broadcase change came in earlier through the cpu hotplug
        branch, but I left the explanation in the commit message since it was
