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

Pull thermal management updates from Zhang Rui:
 "Specifics:

   - enhance Thermal Framework with several new capabilities:

       * use power estimates
       * compute weights with relative integers instead of percentages
       * allow governors to have private data in thermal zones
       * export thermal zone parameters through sysfs

     Thanks to the ARM thermal team (Javi, Punit, KP).

   - introduce a new thermal governor: power allocator.  First in kernel
     closed loop PI(D) controller for thermal control.  Thanks to ARM
     thermal team.

   - enhance OF thermal to allow thermal zones to have sustainable power
     HW specification.  Thanks to Punit.

   - introduce thermal driver for Intel Quark SoC x1000platform.  Thanks
     to Ong, Boon Leong.

   - introduce QPNP PMIC temperature alarm driver.  Thanks to Ivan T. I.

   - introduce thermal driver for Hisilicon hi6220.  Thanks to
     kongxinwei.

   - enhance Exynos thermal driver to handle Exynos5433 TMU.  Thanks to
     Chanwoo C.

   - TI thermal driver now has a better implementation for EOCZ bit.
     From Pavel M.

   - add id for Skylake processors in int340x processor thermal driver.

   - a couple of small fixes and cleanups."
