Merge tag 'thermal-v7.2-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux
Pull thermal driver updates for 7.2 from Daniel Lezcano: - Add the QCom Nord temperature sensor DT bindings (Deepti Jaggi) - Use devm_add_action_or_reset() for clock disable on the NVidia soctherm and switch to devm cooling device registration version (Daniel Lezcano) - Replace the devm version implementation by the helper doing the same thing (Daniel Lezcano) - Add the Amlogic T7 thermal sensor along with thermal calibration data read from SMC calls (Ronald Claveau) - Fix typo in comment, "uppper" with "upper" in the TSens QCom driver (Jinseok Kim) - Add the QCom Shikra temperature sensor DT bindings (Gaurav Kohli) - Add the QCom Hawi temperature sensor DT bindings (Dipa Ramesh Mantre) - Fix atomic temperature read in the QCom tsens to comply with hardware documentation (Priyansh Jain) - Fix trailing whitespace and repeated word in the OF code. Do not split quoted string across lines in the iMX7 driver (Mayur Kumar) - Add SpacemiT K1 thermal sensor support (Shuwei Wu) - Add the i.MX93 temperature sensor support and filter out the invalid temperature (Jacky Bai) - Enable by default the TMU (Thermal Monitoring Unit) on Exynos platform (Krzysztof Kozlowski) - Split the core code and the OF which are interleaved. Add the cooling device per index registration in order to support dedicated cooling devices controller (Daniel Lezcano) - Add DT binding to specify an index in the cooling device map (Gaurav Kohli) - Rework interrupt initialization in the Tsens driver and add the optional wakeup source (Priyansh Jain)" * tag 'thermal-v7.2-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux: (34 commits) thermal/drivers/qcom/tsens: Disable wakeup interrupt setup on automotive targets thermal/drivers/qcom/tsens: Switch wake IRQ handling to PM callbacks thermal/core: Fix missing stub for devm_thermal_cooling_device_register dt-bindings: thermal: cooling-devices: Update support for 3 cells cooling device thermal/of: Support cooling device ID in cooling-spec thermal/of: Pass cdev_id and introduce devm registration helper thermal/of: Add cooling device ID support thermal/of: Rename the devm_thermal_of_cooling_device_register() function thermal/core: Make cooling device OF node conditional on CONFIG_THERMAL_OF thermal/of: Move cooling device OF helpers out of thermal core hwmon: Use non-OF thermal cooling device registration API thermal/core: Add devm_thermal_cooling_device_register() thermal/core: Introduce non-OF thermal_cooling_device_register() thermal/drivers/samsung: Enable TMU by default thermal/driver/qoriq: Workaround unexpected temperature readings from tmu thermal/drivers/qoriq: Add i.MX93 tmu support dt-bindings: thermal: qoriq: Add compatible string for imx93 thermal/drivers/spacemit/k1: Add thermal sensor support dt-bindings: thermal: Add SpacemiT K1 thermal sensor thermal/drivers/imx: Do not split quoted string across lines ...
