Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal
Pull thermal soc updates from Eduardo Valentin:
- thermal core has a new devm_* API for registering cooling devices. I
took the entire series, that is why you see changes on drivers/hwmon
in this pull (Guenter Roeck)
- rockchip thermal driver gains support to PX30 SoC (Elaine Zhang)
- the generic-adc thermal driver now considers the lookup table DT
property as optional (Jean-Francois Dagenais)
- Refactoring of tsens thermal driver (Amit Kucheria)
- Cleanups on cpu cooling driver (Daniel Lezcano)
- broadcom thermal driver dropped support to ACPI (Srinath Mannam)
- tegra thermal driver gains support to OC hw throttle and GPU throtle
(Wei Ni)
- Fixes in several thermal drivers.
