Merge tag 'thermal-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki: "These start a rework of the handling of trip points in the thermal core, improve the cpufreq/devfreq cooling device handling, update some thermal control drivers and the tmon utility and clean up code. Specifics: - Consolidate the thermal core code by beginning to move the thermal trip structure from the thermal OF code as a generic structure to be used by the different sensors when registering a thermal zone (Daniel Lezcano). - Make per cpufreq / devfreq cooling device ops instead of using a global variable, fix comments and rework the trace information (Lukasz Luba). - Add the include/dt-bindings/thermal.h under the area covered by the thermal maintainer in the MAINTAINERS file (Lukas Bulwahn). - Improve the error output by giving the sensor identification when a thermal zone failed to initialize, the DT bindings by changing the positive logic and adding the r8a779f0 support on the rcar3 (Wolfram Sang). - Convert the QCom tsens DT binding to the dtsformat format (Krzysztof Kozlowski). - Remove the pointless get_trend() function in the QCom, Ux500 and tegra thermal drivers, along with the unused DROP_FULL and RAISE_FULL trends definitions. Simplify the code by using clamp() macros (Daniel Lezcano). - Fix ref_table memory leak at probe time on the k3_j72xx bandgap (Bryan Brattlof). - Fix array underflow in prep_lookup_table (Dan Carpenter). - Add static annotation to the k3_j72xx_bandgap_j7* data structure (Jin Xiaoyun). - Fix typos in comments detected on sun8i by Coccinelle (Julia Lawall). - Fix typos in comments on rzg2l (Biju Das). - Remove as unnecessary call to dev_err() as the error is already printed by the failing function on u8500 (Yang Li). - Register the thermal zones as hwmon sensors for the Qcom thermal sensors (Dmitry Baryshkov). - Fix 'tmon' tool compilation issue by adding phtread.h include (Markus Mayer). - Fix typo in the comments for the 'tmon' tool (Slark Xiao). - Make the thermal core use ida_alloc()/free() directly instead of ida_simple_get()/ida_simple_remove() that have been deprecated (keliu). - Drop ACPI_FADT_LOW_POWER_S0 check from the Intel PCH thermal control driver (Rafael Wysocki)" * tag 'thermal-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (39 commits) thermal/of: Initialize trip points separately thermal/of: Use thermal trips stored in the thermal zone thermal/core: Add thermal_trip in thermal_zone thermal/core: Rename 'trips' to 'num_trips' thermal/core: Move thermal_set_delay_jiffies to static thermal/core: Remove unneeded EXPORT_SYMBOLS thermal/of: Move thermal_trip structure to thermal.h thermal/of: Remove the device node pointer for thermal_trip thermal/of: Replace device node match with device node search thermal/core: Remove duplicate information when an error occurs thermal/core: Avoid calling ->get_trip_temp() unnecessarily thermal/tools/tmon: Fix typo 'the the' in comment thermal/tools/tmon: Include pthread and time headers in tmon.h thermal/ti-soc-thermal: Fix comment typo thermal/drivers/qcom/spmi-adc-tm5: Register thermal zones as hwmon sensors thermal/drivers/qcom/temp-alarm: Register thermal zones as hwmon sensors thermal/drivers/u8500: Remove unnecessary print function dev_err() thermal/drivers/rzg2l: Fix comments thermal/drivers/sun8i: Fix typo in comment thermal/drivers/k3_j72xx_bandgap: Make k3_j72xx_bandgap_j721e_data and k3_j72xx_bandgap_j7200_data static ...

-QPNP temperature alarm peripherals are found inside of Qualcomm PMIC chips
-that utilize the Qualcomm SPMI implementation. These peripherals provide an
-interrupt signal and status register to identify high PMIC die temperature.
-

-- compatible: Should contain "qcom,spmi-temp-alarm".
-- reg: Specifies the SPMI address.
-- interrupts: PMIC temperature alarm interrupt.
-- #thermal-sensor-cells: Should be 0. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
-
-Optional properties:
-- io-channels: Should contain IIO channel specifier for the ADC channel,
- which report chip die temperature.
