Merge tag 'thermal-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull thermal control updates from Rafael Wysocki:
 "These update the thermal control sysfs interface and multiple thermal
  control drivers:

   - Convert EAGAIN into ENODATA in temp_show() to prevent user space
     from polling the sysfs file in vain after a failing O_NONBLOCK read
     under the assumption that the read would have blocked (Hsin-Te
     Yuan)

   - Add Wildcat Lake PCI ID to the int340x Intel processor thermal
     driver (Srinivas Pandruvada)

   - Add debugfs interface to override the temperature set by the
     firmware in the Intel platform temperature control (PTC) interface
     and add a new sysfs control attribute called thermal_tolerance to
     it (Srinivas Pandruvada)

   - Enable the stage 2 shutdown in the qcom-spmi-temp-alarm thermal
     driver and add support for more SPMI variants to it (Anjelique
     Melendez)

   - Constify the thermal_zone_device_ops structure where possible in
     several assorted thermal drivers (Christophe Jaillet)

   - Use the dev_fwnode() helper instead of of_fwnode_handle(), as it is
     more adequate, wherever possible in thermal drivers (Jiri Slaby)

   - Implement and document One-Time Programmable fuse support in the
     Rockchip thermal driver in order to increase the precision of the
     measurements (Nicolas Frattaroli)

   - Change the way the Mediatek LTVS thermal driver stores the
     initialization data sequence to support different sequences
     matching different platforms. Introduce mt7988 support with a new
     initialization sequence (Mason Chang)

   - Document the QCom TSens Milos Temperature Sensor DT bindings (Luca
     Weiss)

   - Add the fallback compatible string for MT7981 and MT8516 DT
     bindings (Aleksander Jan Bajkowski)

   - Add the compatible string for the Tegra210B01 SOC_THERM driver
     (Aaron Kling)"

	Update a new temperature target in milli degree celsius for hardware to

``thermal_tolerance`` (RW)

	This attribute ranges from 0 to 7, where 0 represents

	the most aggressive control to avoid any temperature overshoots, and

	7 represents a more graceful approach, favoring performance even at

	the expense of temperature overshoots.

	Note: This level may not scale linearly. For example, a value of 3 does

	value of 0.



Given that this is platform temperature control, it is expected that a

single user-level manager owns and manages the controls. If multiple

user-level software applications attempt to write different targets, it
