Merge tag 'thermal-v6.3-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux into thermal-next
Pull thermal control material for 6.3-rc1 from Daniel Lezcano:
"- Fix kerneldoc format errors for Rockchip, Mediatek and Uniphier
(Randy Dunlap)
- Add the missing 'qcom,adc-tm7' compatible string in the dt-bindings
(Krzysztof Kozlowski)
- Improve the calibration routine by relying on the nvmem to read the
values and provide a set of fixes for the QCom tsens driver (Dmitry
Baryshkov)
- Remove the duplicate interrupt setting routine in the QCom tsens
driver (Daniel Lezcano)
- Fix a wrong loop condition in the i.MX SC thermal driver and add the
iMX8QM sensors (Viorel Suman)
- Fix header inclusion asm-generic.h by asm.h for the
qcom-spmi-adc-tm5 driver (Andy Shevchenko)
- Use the devm_platform_get_and_ioremap_resource() combo function in
all the drivers where the conversion applies (Ye Xingchen)
- Replace a literal mask by an existing corresponding macro (Yangtao
Li)
- Add support for MT7986 and MT7981 (Daniel Golle)
- Use thermal_zone_get_crit_temp() for the Armada thermal driver
(Daniel Lezcano)"
