Merge branch 'thermal-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux 

Pull thermal fixes from Zhang Rui:
 "Specifics:

   - bogus type qualifier fix in OF thermal code.
   - Minor fixes on imx and rcar thermal drivers.
   - Update TI SoC thermal maintainer entry.
   - Updated documentation of OF cpufreq cooling register"

    This interface function registers the cpufreq cooling device with

    order to bind it via the thermal DT code. This api can support multiple

    instances of cpufreq cooling devices.
