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
