Merge tag 'thermal-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki: "These are mostly thermal driver updates, including new thermal drivers for Renesas RZ/G3S and Renesas RZ/G3E SoCs, a new power slider platform feature support in the Intel int340x thermal driver, a new Tegra114- specific SOCTHERM driver and more. There is also a Step-wise thermal governor update allowing it to start reducing cooling somewhat earlier if the temperature of the given thermal zone is falling down and a thermal testing code cleanup. Specifics: - Add new thermal driver for the Renesas RZ/G3S SoC (Claudiu Beznea) - Add new thermal driver for the Renesas RZ/G3E SoC (John Madieu) - Add support for new platform power slider feature to the Intel int340x driver (Srinivas Pandruvada). - Add new Tegra114-specific SOCTHERM driver and document Tegra114 SOCTHERM Thermal Management System in DT bindings (Svyatoslav Ryhel) - Add temperature sensor channel to thermal-generic-adc (Svyatoslav Ryhel) - Add support for per-SoC default trim values to the Renesas rcar_gen3 thermal driver, use it for adding R-Car V4H default trim values, fix a comment typo in that driver and document Gen4 support in its Kconfig entry (Marek Vasut) - Fix mapping SoCs to generic Gen4 entry in the Renesas rcar_gen3 thermal driver (Wolfram Sang) - Document the TSU unit in the r9a08g045-tsu and r9a09g047-tsu DT bindings (Claudiu Beznea, John Madieu) - Make LMH select QCOM_SCM and add missing IRQ includes to the qcom/lmh thermal driver (Dmitry Baryshkov) - Fix incorrect error message in the qcom/lmh thermal driver (Sumeet Pawnikar) - Add QCS615 compatible to tsens thermal DT bindings (Gaurav Kohli) - Document the Glymur temperature sensor in qcom-tsens thermal DT bindings (Manaf Meethalavalappu Pallikunhi) - Make k3_j72xx_bandgap thermal driver register the thermal sensor with hwmon (Michael Walle) - Tighten GRF requirements in the rockchip thermal DT bindings, silence a GRF warning in the rockchip thermal driver and unify struct rockchip_tsadc_chip format in it (Sebastian Reichel) - Update the Step-wise thermal governor to allow it to reduce the cooling level earlier if thermal zone temperature is dropping and clean it up (Rafael Wysocki) - Clean up the thermal testing code (Rafael Wysocki) - Assorted cleanups of thermal drivers (Jiapeng Chong, Salah Triki, Osama Abdelkader)" * tag 'thermal-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (37 commits) thermal/drivers/renesas/rzg3e: Fix add thermal driver for the Renesas RZ/G3E SoC dt-bindings: thermal: qcom-tsens: Document the Glymur temperature Sensor thermal/drivers/renesas/rzg3e: Add thermal driver for the Renesas RZ/G3E SoC dt-bindings: thermal: r9a09g047-tsu: Document the TSU unit thermal/drivers/thermal-generic-adc: Add temperature sensor channel dt-bindings: thermal: rockchip: Tighten grf requirements thermal/drivers/rockchip: Shut up GRF warning thermal/drivers/rockchip: Unify struct rockchip_tsadc_chip format thermal/drivers/renesas/rzg3s: Add thermal driver for the Renesas RZ/G3S SoC dt-bindings: thermal: r9a08g045-tsu: Document the TSU unit thermal/drivers/k3_j72xx_bandgap: Register sensors with hwmon thermal/drivers/rcar_gen3: Fix mapping SoCs to generic Gen4 entry thermal/drivers/tegra: Add Tegra114 specific SOCTHERM driver dt-bindings: thermal: add Tegra114 soctherm header thermal/drivers/tegra/soctherm-fuse: Prepare calibration for Tegra114 support dt-bindings: thermal: Document Tegra114 SOCTHERM Thermal Management System thermal/drivers/rcar_gen3: Document Gen4 support in Kconfig entry thermal/drivers/rcar_gen3: Fix comment typo drivers/thermal/qcom/lmh: Fix incorrect error message thermal/drivers/qcom/lmh: Add missing IRQ includes ...
