Merge tag 'thermal-6.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more thermal control updates from Rafael Wysocki: "These are mostly cleanups on top of the previously merged thermal control changes plus some driver fixes and the removal of the Intel Menlow thermal driver. Specifics: - Add compatible DT bindings for imx6sll and imx6ul to fix a dtbs check warning (Stefan Wahren) - Update the example in the DT bindings to reflect changes with the ADC node name for QCom TM and TM5 (Marijn Suijten) - Fix comments for the cpuidle_cooling_register() function to match the function prototype (Chenggang Wang) - Fix inconsistent temperature read and some Mediatek variant board reboot by reverting a change and handling the temperature differently (AngeloGioacchino Del Regno) - Fix a memory leak in the initialization error path for the Mediatek driver (Kang Chen) - Use of_address_to_resource() in the Mediatek driver (Rob Herring) - Fix unit address in the QCom tsens driver DT bindings (Krzysztof Kozlowski) - Clean up the step-wise thermal governor (Zhang Rui) - Introduce thermal_zone_device() for accessing the device field of struct thermal_zone_device and two drivers use it (Daniel Lezcano) - Clean up the ACPI thermal driver a bit (Daniel Lezcano) - Delete the thermal driver for Intel Menlow platforms that is not expected to have any users (Rafael Wysocki)" * tag 'thermal-6.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: thermal: intel: menlow: Get rid of this driver ACPI: thermal: Move to dedicated function sysfs extra attr creation ACPI: thermal: Use thermal_zone_device() thermal: intel: pch_thermal: Use thermal driver device to write a trace thermal: core: Encapsulate tz->device field thermal: gov_step_wise: Adjust code logic to match comment thermal: gov_step_wise: Delete obsolete comment dt-bindings: thermal: qcom-tsens: Correct unit address thermal/drivers/mediatek: Use of_address_to_resource() thermal/drivers/mediatek: Change clk_prepare_enable to devm_clk_get_enabled in mtk_thermal_probe thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe thermal/drivers/mediatek: Add temperature constraints to validate read Revert "thermal/drivers/mediatek: Add delay after thermal banks initialization" thermal/drivers/cpuidle_cooling: Delete unmatched comments dt-bindings: thermal: Use generic ADC node name in examples dt-bindings: imx-thermal: Add imx6sll and imx6ul compatible
