Linus Torvalds 02f9fc286e Power management updates for 5.12-rc1
- Add new power capping facility called DTPM (Dynamic Thermal Power
    Management), based on the existing power capping framework, to
    allow aggregate power constraints to be applied to sets of devices
    in a distributed manner, along with a CPU backend driver based on
    the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King).
 
  - Add AlderLake Mobile support to the Intel RAPL power capping
    driver and make it use the topology interface when laying out the
    system topology (Zhang Rui, Yunfeng Ye).
 
  - Drop the cpufreq tango driver belonging to a platform that is not
    supported any more (Arnd Bergmann).
 
  - Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq
    driver flags (Viresh Kumar).
 
  - Update cpufreq drivers:
 
    * Fix max CPU frequency discovery in the intel_pstate driver and
      make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
      Christian).
 
    * Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe
      JAILLET).
 
    * Make the tegra20 driver use the resource-managed API (Dmitry
      Osipenko).
 
    * Enable boost support in the qcom-hw driver (Shawn Guo).
 
  - Update the operating performance points (OPP) framework:
 
    * Clean up the OPP core (Dmitry Osipenko, Viresh Kumar).
 
    * Extend the OPP API by adding new helpers to it (Dmitry Osipenko,
      Viresh Kumar).
 
    * Allow required OPPs to be used for devfreq devices and update
      the devfreq governor code accordingly (Saravana Kannan).
 
    * Prepare the framework for introducing new dev_pm_opp_set_opp()
      helper (Viresh Kumar).
 
    * Drop dev_pm_opp_set_bw() and update related drivers (Viresh
      Kumar).
 
    * Allow lazy linking of required-OPPs (Viresh Kumar).
 
  - Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
    Pierre Kuo).
 
  - Update the generic power domains (genpd) framework:
 
    * Use device's next wakeup to determine domain idle state (Lina
      Iyer).
 
    * Improve initialization and debug (Dmitry Osipenko).
 
    * Simplify computations (Abaci Team).
 
  - Make janitorial changes in the core code handling system sleep
    and PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,
    Zqiang).
 
  - Update the MAINTAINERS entry for the exynos cpuidle driver and
    drop DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom
    Rix).
 
  - Extend the PM clock layer to cover clocks that must sleep (Nicolas
    Pitre).
 
  - Update the cpupower utility:
 
    * Update cpupower command, add support for AMD family 0x19 and clean
      up the code to remove many of the family checks to make future
      family updates easier (Nathan Fontenot, Robert Richter).
 
    * Add Makefile dependencies for install targets to allow building
      cpupower in parallel rather than serially (Ivan Babrou).
 
  - Make janitorial changes in power management Kconfig (Lukasz Luba).

Pull power management updates from Rafael Wysocki:
 "These add a new power capping facility allowing aggregate power
  constraints to be applied to sets of devices in a distributed manner,
  add a new CPU ID to the RAPL power capping driver and improve it, drop
  a cpufreq driver belonging to a platform that is not supported any
  more, drop two redundant cpufreq driver flags, update cpufreq drivers
  (intel_pstate, brcmstb-avs, qcom-hw), update the operating performance
  points (OPP) framework (code cleanups, new helpers, devfreq-related
  modifications), clean up devfreq, extend the PM clock layer, update
  the cpupower utility and make assorted janitorial changes.
