Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal updates from Zhang Rui:
- use int instead of unsigned long to represent temperature to avoid
bogus overheat detection when negative temperature reported. From
Sascha Hauer.
- export available thermal governors information to user space via
sysfs. From Wei Ni.
- introduce new thermal driver for Wildcat Point platform controller
hub, which uses PCH thermal sensor and associated critical and hot
trip points. From Tushar Dave.
- add suuport for Intel Skylake and Denlow platforms in powerclamp
driver.
- some small cleanups in thermal core.
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
thermal: Add Intel PCH thermal driver
thermal: Add comment explaining test for critical temperature
thermal: Use IS_ENABLED instead of #ifdef
thermal: remove unnecessary call to thermal_zone_device_set_polling
thermal: trivial: fix typo in comment
thermal: consistently use int for temperatures
thermal: add available policies sysfs attribute
thermal/powerclamp: add cpu id for denlow platform
thermal/powerclamp: add cpu id for Skylake u/y
thermal/powerclamp: add cpu id for skylake h/s
