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

Pull thermal SoC updates from Zhang Rui:
 "Thermal SoC management updates:

   - imx thermal driver now supports i.MX7 thermal sensor (Anson Huang)

   - exynos thermal driver dropped support for exynos 5440 (Krzysztof
     Kozlowski)

   - rcar_thermal now supports r8a77995 (Yoshihiro Kaneko)

   - rcar_gen3_thermal now supports r8a77965 (Niklas Söderlund)

   - qcom-spmi-temp-alarm now supports GEN2 PMIC peripherals (David
     Collins)

   - uniphier thermal now supports UniPhier PXs3 (Kunihiko Hayashi)

   - mediatek thermal now supports MT7622 SoC (Sean Wang)

   - considerable refactoring of exynos driver (Bartlomiej
     Zolnierkiewicz)

   - small fixes all over the place on different drivers"
