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)" * tag 'thermal-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (39 commits) thermal/drivers/qcom/temp-alarm: Use dev_err_probe thermal/drivers/generic-adc: Register thermal zones as hwmon sensors thermal/drivers/mediatek/lvts_thermal: Remove redundant msg in lvts_ctrl_start() thermal/drivers/qcom: Remove redundant msg at probe time thermal/drivers/ti-soc: Remove redundant msg in ti_thermal_expose_sensor() thermal/drivers/qoriq: Remove redundant msg in qoriq_tmu_register_tmu_zone() thermal/drivers/tegra: Remove redundant msg in tegra_tsensor_register_channel() drivers/thermal/k3: Remove redundant msg in k3_bandgap_probe() thermal/drivers/imx: Remove redundant msg in imx8mm_tmu_probe() and imx_sc_thermal_probe() thermal/drivers/amlogic: Remove redundant msg in amlogic_thermal_probe() thermal/drivers/sun8i: Remove redundant msg in sun8i_ths_register() thermal/hwmon: Add error information printing for devm_thermal_add_hwmon_sysfs() thermal/drivers/stm32: Convert to platform remove callback returning void net/mlx5: Update the driver with the recent thermal changes thermal/drivers/armada: Add support for AP807 thermal data dt-bindings: armada-thermal: Add armada-ap807-thermal compatible thermal/drivers/qoriq: Support version 2.1 thermal/drivers/qoriq: Only enable supported sensors thermal/drivers/qoriq: No need to program site adjustment register thermal/drivers/mediatek/lvts_thermal: Register thermal zones as hwmon sensors ...
