Linus Torvalds 0e285e9088 Power management updates for v4.12-rc1
- Rework the intel_pstate driver's sysfs interface to make it
    more straightforward and more intuitive (Rafael Wysocki).
 
  - Make intel_pstate support all processors which advertise HWP
    (hardware-managed P-states) to the kernel in all operation modes
    and make it use the load-based P-state selection algorithm on a
    wider range of systems in the active mode (Rafael Wysocki).
 
  - Add cpufreq driver for Tegra186 (Mikko Perttunen).
 
  - Add support for Gemini Lake SoCs to intel_pstate (David Box).
 
  - Add support for MT8176 and MT817x to the Mediatek cpufreq driver
    and clean up that driver a bit (Daniel Kurtz).
 
  - Clean up intel_pstate and optimize it slightly (Rafael Wysocki).
 
  - Update the schedutil cpufreq governor, mostly to fix a couple of
    issues with it related to specific workloads, and rework its sysfs
    tunable and initialization a bit (Rafael Wysocki, Viresh Kumar).
 
  - Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers
    (Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar,
    YuanTian Tang).
 
  - Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert
    Uytterhoeven).
 
  - Add support for "always on" power domains to the genpd (generic
    power domains) framework and clean up that code somewhat (Ulf
    Hansson, Lina Iyer, Viresh Kumar).
 
  - Fix minor issues in the powernv cpuidle driver and clean it up
    (Anton Blanchard, Gautham Shenoy).
 
  - Move the AnalyzeSuspend utility under tools/power/pm-graph/ and
    add an analogous boot-profiling utility called AnalyzeBoot to it
    (Todd Brandt).
 
  - Add rk3328 support to the rockchip-io AVS (Adaptive Voltage
    Scaling) driver (David Wu).
 
  - Fix minor issues in the cpuidle core, the intel_pstate_tracer
    utility, the devfreq framework and the PM core documentation
    (Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski).

Merge tag 'pm-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "This time the majority of changes go to the cpufreq subsystem (and to
  the intel_pstate driver in particular) and there are some updates in
  the generic power domains framework, cpuidle, tools and a couple of
  other places.

  One thing worth mentioning is that the intel_pstate's sysfs interface
  has been reworked to be more consistent with the general expectations
  of the cpufreq core and less confusing, hopefully for the better.
  Also, we have a new cpufreq driver for Tegra186 and new hardware
  support in intel_pstata and the Mediatek cpufreq driver.

  Apart from that, the AnalyzeSuspend utility for system suspend
  profiling gets a companion called AnalyzeBoot for the analogous
  profiling of system boot and they both go into one place under
  tools/power/pm-graph/.

  The rest is mostly fixes, cleanups and code reorganization.

  Specifics:

   - Rework the intel_pstate driver's sysfs interface to make it more
     straightforward and more intuitive (Rafael Wysocki).

   - Make intel_pstate support all processors which advertise HWP
     (hardware-managed P-states) to the kernel in all operation modes
     and make it use the load-based P-state selection algorithm on a
     wider range of systems in the active mode (Rafael Wysocki).

   - Add cpufreq driver for Tegra186 (Mikko Perttunen).

   - Add support for Gemini Lake SoCs to intel_pstate (David Box).

   - Add support for MT8176 and MT817x to the Mediatek cpufreq driver
     and clean up that driver a bit (Daniel Kurtz).

   - Clean up intel_pstate and optimize it slightly (Rafael Wysocki).

   - Update the schedutil cpufreq governor, mostly to fix a couple of
     issues with it related to specific workloads, and rework its sysfs
     tunable and initialization a bit (Rafael Wysocki, Viresh Kumar).

   - Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers
     (Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar,
     YuanTian Tang).

   - Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert
     Uytterhoeven).

   - Add support for "always on" power domains to the genpd (generic
     power domains) framework and clean up that code somewhat (Ulf
     Hansson, Lina Iyer, Viresh Kumar).

   - Fix minor issues in the powernv cpuidle driver and clean it up
     (Anton Blanchard, Gautham Shenoy).

     an analogous boot-profiling utility called AnalyzeBoot to it (Todd
     Brandt).

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
