Hi Linus,

Please pull from the tag

 thermal-6.8-rc1

with top-most commit 17e8b76491b007698cf63bc10093bc8991e45001

 Merge branch 'thermal-intel'

on top of commit 98b1cc82c4affc16f5598d4fa14b1858671b2263

 Linux 6.7-rc2

to receive thermal control updates for 6.8-rc1.

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
   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 (Rafa=C5=82 Mi=C5=82ecki).

 - 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-K=C3=B6nig)

 - 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).

Thanks!
