Pull thermal control updates from Rafael Wysocki:
"These add Nova Lake processor support to the Intel thermal drivers and
DPTF code, update thermal control documentation, simplify the ACPI
DPTF code related to thermal control, add QCS8300 compatible to the
tsens thermal DT bindings, add DT bindings for NXP i.MX91 thermal
module and add support for it to the imx91 thermal driver, update a
few other thermal drivers and fix a format string issue in a thermal
utility:
- Add Nova Lake processor thermal device to the int340x
processor_thermal driver, add DLVR support for Nova Lake to it, add
Nova Lake support to the ACPI DPTF code, document thermal
throttling on Intel platforms, and update workload type hint
interface documentation (Srinivas Pandruvada)
- Remove int340x thermal scan handler from the ACPI DPTF code because
it turned out to be unnecessary (Slawomir Rosek)
- Clean up the Intel int340x thermal driver (Kaushlendra Kumar)
- Document the RZ/V2H TSU DT bindings (Ovidiu Panait)
- Document the Kaanapali Temperature Sensor (Manaf Meethalavalappu
Pallikunhi)
- Document R-Car Gen4 and RZ/G2 support in driver comment (Marek
Vasut)
- Convert to DEFINE_SIMPLE_DEV_PM_OPS() in R-Car [Gen3] (Geert
Uytterhoeven)
- Fix format string bug in thermal-engine (Malaya Kumar Rout)
- Make ipq5018 tsens standalone compatible (George Moussalem)
- Add the QCS8300 compatible for QCom Tsens (Gaurav Kohli)
- Add support for the NXP i.MX91 thermal module, including the DT
bindings (Pengfei Li)"
