Linus Torvalds 6d277aca48 Power management updates for 5.6-rc1
- Update the ACPI processor driver in order to export
    acpi_processor_evaluate_cst() to the code outside of it, add
    ACPI support to the intel_idle driver based on that and clean
    up that driver somewhat (Rafael Wysocki).
 
  - Add an admin guide document for the intel_idle driver (Rafael
    Wysocki).
 
  - Clean up cpuidle core and drivers, enable compilation testing
    for some of them (Benjamin Gaignard, Krzysztof Kozlowski, Rafael
    Wysocki, Yangtao Li).
 
  - Fix reference counting of OPP (operating performance points) table
    structures (Viresh Kumar).
 
  - Add support for CPR (Core Power Reduction) to the AVS (Adaptive
    Voltage Scaling) subsystem (Niklas Cassel, Colin Ian King,
    YueHaibing).
 
  - Add support for TigerLake Mobile and JasperLake to the Intel RAPL
    power capping driver (Zhang Rui).
 
  - Update cpufreq drivers:
 
    * Add i.MX8MP support to imx-cpufreq-dt (Anson Huang).
 
    * Fix usage of a macro in loongson2_cpufreq (Alexandre Oliva).
 
    * Fix cpufreq policy reference counting issues in s3c and
      brcmstb-avs (chenqiwu).
 
    * Fix ACPI table reference counting issue and HiSilicon quirk
      handling in the CPPC driver (Hanjun Guo).
 
    * Clean up spelling mistake in intel_pstate (Harry Pan).
 
    * Convert the kirkwood and tegra186 drivers to using
      devm_platform_ioremap_resource() (Yangtao Li).
 
  - Update devfreq core:
 
    * Add 'name' sysfs attribute for devfreq devices (Chanwoo Choi).
 
    * Clean up the handing of transition statistics and allow them
      to be reset by writing 0 to the 'trans_stat' devfreq device
      attribute in sysfs (Kamil Konieczny).
 
    * Add 'devfreq_summary' to debugfs (Chanwoo Choi).
 
    * Clean up kerneldoc comments and Kconfig indentation (Krzysztof
      Kozlowski, Randy Dunlap).
 
  - Update devfreq drivers:
 
    * Add dynamic scaling for the imx8m DDR controller and clean up
      imx8m-ddrc (Leonard Crestez, YueHaibing).
 
    * Fix DT node reference counting and nitialization error code path
      in rk3399_dmc and add COMPILE_TEST and HAVE_ARM_SMCCC dependency
      for it (Chanwoo Choi, Yangtao Li).
 
    * Fix DT node reference counting in rockchip-dfi and make it use
      devm_platform_ioremap_resource() (Yangtao Li).
 
    * Fix excessive stack usage in exynos-ppmu (Arnd Bergmann).
 
    * Fix initialization error code paths in exynos-bus (Yangtao Li).
 
    * Clean up exynos-bus and exynos somewhat (Artur Świgoń, Krzysztof
      Kozlowski).
 
  - Add tracepoints for tracking usage_count updates unrelated to
    status changes in PM-runtime (Michał Mirosław).
 
  - Add sysfs attribute to control the "sync on suspend" behavior
    during system-wide suspend (Jonas Meurer).
 
  - Switch system-wide suspend tests over to 64-bit time (Alexandre
    Belloni).
 
  - Make wakeup sources statistics in debugfs cover deleted ones which
    used to be the case some time ago (zhuguangqing).
 
  - Clean up computations carried out during hibernation, update
    messages related to hibernation and fix a spelling mistake in one
    of them (Wen Yang, Luigi Semenzato, Colin Ian King).
 
  - Add mailmap entry for maintainer e-mail address that has not been
    functional for several years (Rafael Wysocki).

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
