Linus Torvalds 7f73ba68cf Thermal control updates for 6.8-rc1
- Add dynamic thresholds for trip point crossing detection to prevent
    trip point crossing notifications from being sent at incorrect times
    or not at all in some cases (Rafael J. Wysocki).
 
  - Fix synchronization issues related to the resume of thermal zones
    during a system-wide resume and allow thermal zones to be resumed
    concurrently (Rafael J. Wysocki).
 
  - Modify the thermal zone unregistration to wait for the given zone to
    go away completely before returning to the caller and rework the
    sysfs interface for trip points on top of that (Rafael J. Wysocki).
 
  - Fix a possible NULL pointer dereference in thermal zone registration
    error path (Rafael J. Wysocki).
 
  - Clean up the IPA thermal governor and modify it (with the help of a
    new governor callback) to avoid allocating and freeing memory every
    time its throttling callback is invoked (Lukasz Luba).
 
  - Make the IPA thermal governor handle thermal instance weight changes
    via sysfs correctly (Lukasz Luba).
 
  - Update the thermal netlink code to avoid sending messages if there
    are no recipients (Stanislaw Gruszka).
 
  - Convert Mediatek Thermal to the json-schema (Rafał Miłecki).
 
  - Fix thermal DT bindings issue on Loongson (Binbin Zhou).
 
  - Fix returning NULL instead of -ENODEV during thermal probe on
    Loogsoon (Binbin Zhou).
 
  - Add thermal DT binding for tsens on the SM8650 platform (Neil
    Armstrong).
 
  - Add reboot on the critical trip point crossing option feature (Fabio
    Estevam).
 
  - Use DEFINE_SIMPLE_DEV_PM_OPS do define PM functions for thermal
    suspend/resume on AmLogic (Uwe Kleine-König)
 
  - Add D1/T113s THS controller support to the Sun8i thermal control
    driver (Maxim Kiselev)
 
  - Fix example in the thermal DT binding for QCom SPMI (Johan Hovold).
 
  - Fix compilation warning in the tmon utility (Florian Eckert).
 
  - Add support for interrupt-based thermal configuration on Exynos along
    with a set of related cleanups (Mateusz Majewski).
 
  - Make the Intel HFI thermal driver enable an HFI instance (eg. processor
    package) from its first online CPU and disable it when the last CPU in
    it goes offline (Ricardo Neri).
 
  - Fix a kernel-doc warning and a spello in the cpuidle_cooling thermal
    driver (Randy Dunlap).
 
  - Move the .get_temp() thermal zone callback presence check to the
    thermal zone registration code (Daniel Lezcano).
 
  - Use the for_each_trip() macro for trip points table walks in a few
    places in the thermal core (Rafael J. Wysocki).
 
  - Make all trip point updates (via sysfs as well as from the platform
    firmware) trigger trip change notifications (Rafael J. Wysocki).
 
  - Drop redundant code from the thermal core and make one function in
    it take a const pointer argument (Rafael J. Wysocki).

Pull thermal control updates from Rafael Wysocki:
 "These add support for the D1/T113s THS controller to the sun8i driver
  and a DT-based mechanism for platforms to indicate a preference to
  reboot (instead of shutting down) on crossing a critical trip point,
  fix issues, make other improvements (in the IPA governor, the Intel
  HFI driver, the exynos driver and the thermal netlink interface among
  other places) and clean up code.

  One long-standing issue addressed here is that trip point crossing
  notifications sent to user space might be unreliable due to the
  incorrect handling of trip point hysteresis in the thermal core:
  multiple notifications might be sent for the same event or there might
  be events without any notification at all.

  Specifics:

   - Add dynamic thresholds for trip point crossing detection to prevent
     trip point crossing notifications from being sent at incorrect
     times or not at all in some cases (Rafael J. Wysocki)

   - Fix synchronization issues related to the resume of thermal zones

README

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.
