Thermal control updates for 5.20-rc1
- 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).

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.

trip structure from the thermal OF code as a generic structure to

Qualcomm QPNP PMIC Temperature Alarm
|

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.
|

|

Required properties:
|

- 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.
|
