Merge tag 'thermal-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "These extend the int340x thermal driver, add thermal DT bindings for
  some Qcom platforms, add DT bindings and support for Armada AP807 and
  MSM8909, allow selecting the bang-bang thermal governor as the default
  one, address issues in several thermal drivers for ARM platforms and
  clean up code.

  Specifics:

   - Add new IOCTLs to the int340x thermal driver to allow user space to
     retrieve the Passive v2 thermal table (Srinivas Pandruvada)

   - Add DT bindings for SM6375, MSM8226 and QCM2290 Qcom platforms
     (Konrad Dybcio)

   - Add DT bindings and support for QCom MSM8226 (Matti Lehtimäki)

   - Add DT bindings for QCom ipq9574 (Praveenkumar I)

   - Convert bcm2835 DT bindings to the yaml schema (Stefan Wahren)

   - Allow selecting the bang-bang governor as default (Thierry Reding)

   - Refactor and prepare the code to set the scene for RCar Gen4
     (Wolfram Sang)

   - Clean up and fix the QCom tsens drivers. Add DT bindings and
     calibration for the MSM8909 platform (Stephan Gerhold)

   - Revert a patch introducing a wrong usage of devm_of_iomap() on the
     Mediatek platform (Ricardo Cañuelo)

   - Fix the clock vs reset ordering in order to conform to the
     documentation on the sun8i (Christophe JAILLET)

   - Prevent setting up undocumented registers, enable the only
     described sensors and add the version 2.1 on the Qoriq sensor (Peng
     Fan)

   - Add DT bindings and support for the Armada AP807 (Alex Leibovich)

   - Update the mlx5 driver with the recent thermal changes (Daniel
     Lezcano)

   - Convert to platform remove callback returning void on STM32 (Uwe
     Kleine-König)

   - Add an error information printing for devm_thermal_add_hwmon_sysfs()
     and remove the error from the Sun8i, Amlogic, i.MX, TI, K3, Tegra,
     Qoriq, Mediateka and QCom (Yangtao Li)

   - Register as hwmon sensor for the Generic ADC (Chen-Yu Tsai)

   - Use the dev_err_probe() function in the QCom tsens alarm driver
     (Luca Weiss)"
