Merge tag 'thermal-v5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Pull thermal updates from Daniel Lezcano:

 - Add the tegra3 thermal sensor and fix the compilation testing on
   tegra by adding a dependency on ARCH_TEGRA along with COMPILE_TEST
   (Dmitry Osipenko)

 - Fix the error code for the exynos when devm_get_clk() fails (Dan
   Carpenter)

 - Add the TCC cooling support for AlderLake platform (Sumeet Pawnikar)

 - Add support for hardware trip points for the rcar gen3 thermal driver
   and store TSC id as unsigned int (Niklas Söderlund)

 - Replace the deprecated CPU-hotplug functions get_online_cpus() and
   put_online_cpus (Sebastian Andrzej Siewior)

 - Add the thermal tools directory in the MAINTAINERS file (Daniel
   Lezcano)

 - Fix the Makefile and the cross compilation flags for the userspace
   'tmon' tool (Rolf Eike Beer)

 - Allow to use the IMOK independently from the GDDV on Int340x (Sumeet
   Pawnikar)

 - Fix the stub thermal_cooling_device_register() function prototype
   which does not match the real function (Arnd Bergmann)

 - Make the thermal trip point optional in the DT bindings (Maxime
   Ripard)

 - Fix a typo in a comment in the core code (Geert Uytterhoeven)

 - Reduce the verbosity of the trace in the SoC thermal tegra driver
   (Dmitry Osipenko)

 - Add the support for the LMh (Limit Management hardware) driver on the
   QCom platforms (Thara Gopinath)

 - Allow processing of HWP interrupt by adding a weak function in the
   Intel driver (Srinivas Pandruvada)

 - Prevent an abort of the sensor probe is a channel is not used
   (Matthias Kaehlcke)
