Merge tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki: "As far as new functionality is concerned, there is a new thermal driver for the Intel Hardware Feedback Interface (HFI) along with some intel-speed-select utility changes to support it. There are also new DT compatible strings for a couple of platforms, and thermal zones on some platforms will be registered as HWmon sensors now. Apart from the above, some drivers are updated (fixes mostly) and there is a new piece of documentation for the Intel DPTF (Dynamic Power and Thermal Framework) sysfs interface. Specifics: - Add a new thermal driver for the Intel Hardware Feedback Interface (HFI) including the HFI initialization, HFI notification interrupt handling and sending CPU capabilities change messages to user space via the thermal netlink interface (Ricardo Neri, Srinivas Pandruvada, Nathan Chancellor, Randy Dunlap). - Extend the intel-speed-select utility to handle out-of-band CPU configuration changes and add support for the CPU capabilities change messages sent over the thermal netlink interface by the new HFI thermal driver to it (Srinivas Pandruvada). - Convert the DT bindings to yaml format for the Exynos platform and fix and update the MAINTAINERS file for this driver (Krzysztof Kozlowski). - Register the thermal zones as HWmon sensors for the QCom's Tsens driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour). - Add the msm8953 compatible documentation in the bindings (Luca Weiss). - Add the sm8150 platform support to the QCom LMh driver's DT binding (Thara Gopinath). - Check the command result from the IPC command to the BPMP in the Tegra driver (Mikko Perttunen). - Silence the error for normal configuration where the interrupt is optionnal in the Broadcom thermal driver (Florian Fainelli). - Remove remaining dead code from the TI thermal driver (Yue Haibing). - Don't use bitmap_weight() in end_power_clamp() in the powerclamp driver (Yury Norov). - Update the OS policy capabilities handshake in the int340x thermal driver (Srinivas Pandruvada). - Increase the policies bitmap size in int340x (Srinivas Pandruvada). - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the int340x thermal driver (Rafael Wysocki). - Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang). - Add Intel Dynamic Power and Thermal Framework (DPTF) kernel interface documentation (Srinivas Pandruvada). - Fix bullet list warning in the thermal documentation (Randy Dunlap)" * tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (30 commits) thermal: int340x: Update OS policy capability handshake thermal: int340x: Increase bitmap size Documentation: thermal: DPTF Documentation MAINTAINERS: thermal: samsung: update Krzysztof Kozlowski's email thermal/drivers/ti-soc-thermal: Remove unused function ti_thermal_get_temp() thermal/drivers/brcmstb_thermal: Interrupt is optional thermal: tegra-bpmp: Handle errors in BPMP response drivers/thermal/ti-soc-thermal: Add hwmon support dt-bindings: thermal: tsens: Add msm8953 compatible dt-bindings: thermal: Add sm8150 compatible string for LMh thermal/drivers/qcom/lmh: Add support for sm8150 thermal/drivers/tsens: register thermal zones as hwmon sensors MAINTAINERS: thermal: samsung: Drop obsolete properties dt-bindings: thermal: samsung: Convert to dtschema tools/power/x86/intel-speed-select: v1.12 release tools/power/x86/intel-speed-select: HFI support tools/power/x86/intel-speed-select: OOB daemon mode thermal: intel: hfi: INTEL_HFI_THERMAL depends on NET thermal: netlink: Fix parameter type of thermal_genl_cpu_capability_event() stub thermal: Replace acpi_bus_get_device() ...

-* Exynos Thermal Management Unit (TMU)
-
-** Required properties:
-
-- compatible : One of the following:
- "samsung,exynos3250-tmu"
- "samsung,exynos4412-tmu"
- "samsung,exynos4210-tmu"
- "samsung,exynos5250-tmu"
- "samsung,exynos5260-tmu"
- "samsung,exynos5420-tmu" for TMU channel 0, 1 on Exynos5420
- "samsung,exynos5420-tmu-ext-triminfo" for TMU channels 2, 3 and 4
- Exynos5420 (Must pass triminfo base and triminfo clock)
- "samsung,exynos5433-tmu"
- "samsung,exynos7-tmu"
-- reg : Address range of the thermal registers. For soc's which has multiple
- instances of TMU and some registers are shared across all TMU's like
- interrupt related then 2 set of register has to supplied. First set
- belongs to register set of TMU instance and second set belongs to
- registers shared with the TMU instance.
-
- NOTE: On Exynos5420, the TRIMINFO register is misplaced for TMU
- channels 2, 3 and 4
- Use "samsung,exynos5420-tmu-ext-triminfo" in cases, there is a misplaced
- register, also provide clock to access that base.
-
- TRIMINFO at 0x1006c000 contains data for TMU channel 3
- TRIMINFO at 0x100a0000 contains data for TMU channel 4
- TRIMINFO at 0x10068000 contains data for TMU channel 2
-
-- interrupts : Should contain interrupt for thermal system
-- clocks : The main clocks for TMU device
- -- 1. operational clock for TMU channel
- -- 2. optional clock to access the shared registers of TMU channel
- -- 3. optional special clock for functional operation
-- clock-names : Thermal system clock name
- -- "tmu_apbif" operational clock for current TMU channel
- -- "tmu_triminfo_apbif" clock to access the shared triminfo register
- for current TMU channel
- -- "tmu_sclk" clock for functional operation of the current TMU
- channel
-
-The Exynos TMU supports generating interrupts when reaching given
-temperature thresholds. Number of supported thermal trip points depends
-on the SoC (only first trip points defined in DT will be configured):
- - most of SoC: 4
- - samsung,exynos5433-tmu: 8
- - samsung,exynos7-tmu: 8
-
-** Optional properties:
-
-- vtmu-supply: This entry is optional and provides the regulator node supplying
- voltage to TMU. If needed this entry can be placed inside
- board/platform specific dts file.
-
-Example 1):
-
- tmu@100c0000 {
- compatible = "samsung,exynos4412-tmu";
- interrupt-parent = <&combiner>;
- reg = <0x100C0000 0x100>;
- interrupts = <2 4>;
- clocks = <&clock 383>;
- clock-names = "tmu_apbif";
- vtmu-supply = <&tmu_regulator_node>;
- #thermal-sensor-cells = <0>;
- };
-
-Example 2): (In case of Exynos5420 "with misplaced TRIMINFO register")
- tmu_cpu2: tmu@10068000 {
- compatible = "samsung,exynos5420-tmu-ext-triminfo";
- reg = <0x10068000 0x100>, <0x1006c000 0x4>;
- interrupts = <0 184 0>;
- clocks = <&clock 318>, <&clock 318>;
- clock-names = "tmu_apbif", "tmu_triminfo_apbif";
- #thermal-sensor-cells = <0>;
- };
-
- tmu_cpu3: tmu@1006c000 {
- compatible = "samsung,exynos5420-tmu-ext-triminfo";
- reg = <0x1006c000 0x100>, <0x100a0000 0x4>;
- interrupts = <0 185 0>;
- clocks = <&clock 318>, <&clock 319>;
- clock-names = "tmu_apbif", "tmu_triminfo_apbif";
- #thermal-sensor-cells = <0>;
- };
-
- tmu_gpu: tmu@100a0000 {
- compatible = "samsung,exynos5420-tmu-ext-triminfo";
- reg = <0x100a0000 0x100>, <0x10068000 0x4>;
- interrupts = <0 215 0>;
- clocks = <&clock 319>, <&clock 318>;
- clock-names = "tmu_apbif", "tmu_triminfo_apbif";
- #thermal-sensor-cells = <0>;
- };
-
-Note: For multi-instance tmu each instance should have an alias correctly
-numbered in "aliases" node.
-
-Example:
-
-aliases {
- tmuctrl0 = &tmuctrl_0;
- tmuctrl1 = &tmuctrl_1;
- tmuctrl2 = &tmuctrl_2;
-};
