Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal management updates from Zhang Rui:

 - Fix a problem where orderly_shutdown() is called for multiple times
   due to multiple critical overheating events raised in a short period
   by platform thermal driver. (Keerthy)

 - Introduce a backup thermal shutdown mechanism, which invokes
   kernel_power_off()/emergency_restart() directly, after
   orderly_shutdown() being issued for certain amount of time(specified
   via Kconfig). This is useful in certain conditions that userspace may
   be unable to power off the system in a clean manner and leaves the
   system in a critical state, like in the middle of driver probing
   phase. (Keerthy)

 - Introduce a new interface in thermal devfreq_cooling code so that the
   driver can provide more precise data regarding actual power to the
   thermal governor every time the power budget is calculated. (Lukasz
   Luba)

 - Introduce BCM 2835 soc thermal driver and northstar thermal driver,
   within a new sub-folder. (Rafał Miłecki)

 - Introduce DA9062/61 thermal driver. (Steve Twiss)

 - Remove non-DT booting on TI-SoC driver. Also add support to fetching
   coefficients from DT. (Keerthy)

 - Refactorf RCAR Gen3 thermal driver. (Niklas Söderlund)

 - Small fix on MTK and intel-soc-dts thermal driver. (Dawei Chien,
   Brian Bian)

+	  Thermal subsystem will issue a graceful shutdown when

+	  case of failure of an orderly_poweroff(), the thermal emergency
