Pull thermal control updates for 6.5-rc1 from Daniel Lezcano:

"- 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)

 - Cleanup and fixes for 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)"
