Merge tag 'thermal-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki: "These add support for a new feature, Platform Temperature Control (PTC), to the Intel int340x thermal driver, add support for the Airoha EN7581 thermal sensor and the IPQ5018 platform, fix up the ACPI thermal zones handling, fix other assorted issues and clean up code Specifics: - Add Platform Temperature Control (PTC) support to the Intel int340x thermal driver (Srinivas Pandruvada) - Make the Hisilicon thermal driver compile by default when ARCH_HISI is set (Krzysztof Kozlowski) - Clean up printk() format by using %pC instead of %pCn in the bcm2835 thermal driver (Luca Ceresoli) - Fix variable name coding style in the AmLogic thermal driver (Enrique Isidoro Vazquez Ramos) - Fix missing debugfs entry removal on failure by using the devm_ variant in the LVTS thermal driver (AngeloGioacchino Del Regno) - Remove the unused lvts_debugfs_exit() function as the devm_ variant introduced before takes care of removing the debugfs entry in the LVTS driver (Arnd Bergmann) - Add the Airoha EN7581 thermal sensor support along with its DT bindings (Christian Marangi) - Add ipq5018 compatible string DT binding, cleanup and add its suppot to the QCom Tsens thermal driver (Sricharan Ramabadhran, George Moussalem) - Fix comments typos in the Airoha driver (Christian Marangi, Colin Ian King) - Address a sparse warning by making a local variable static in the QCom thermal driver (George Moussalem) - Fix the usage of the _SCP control method in the driver for ACPI thermal zones (Armin Wolf)" * tag 'thermal-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: thermal: qcom: ipq5018: make ops_ipq5018 struct static thermal/drivers/airoha: Fix spelling mistake "calibrarion" -> "calibration" ACPI: thermal: Execute _SCP before reading trip points ACPI: OSI: Stop advertising support for "3.0 _SCP Extensions" thermal/drivers/airoha: Fix spelling mistake thermal/drivers/qcom/tsens: Add support for IPQ5018 tsens thermal/drivers/qcom/tsens: Add support for tsens v1 without RPM thermal/drivers/qcom/tsens: Update conditions to strictly evaluate for IP v2+ dt-bindings: thermal: qcom-tsens: Add ipq5018 compatible thermal/drivers: Add support for Airoha EN7581 thermal sensor dt-bindings: thermal: Add support for Airoha EN7581 thermal sensor thermal/drivers/mediatek/lvts: Remove unused lvts_debugfs_exit thermal/drivers/mediatek/lvts: Fix debugfs unregister on failure thermal/drivers/amlogic: Rename Uptat to uptat to follow kernel coding style vsprintf: remove redundant and unused %pCn format specifier thermal/drivers/bcm2835: Use %pC instead of %pCn thermal/drivers/hisi: Do not enable by default during compile testing thermal: int340x: processor_thermal: Platform temperature control documentation thermal: intel: int340x: Enable platform temperature control thermal: intel: int340x: Add platform temperature control interface
