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
