The Exynos TMU supports generating interrupts when reaching given

temperature thresholds. Number of supported thermal trip points depends

on the SoC (only first trip points defined in DT will be configured):

 - most of SoC: 4

 - samsung,exynos5433-tmu: 8

 - samsung,exynos7-tmu: 8



Following properties are mandatory (depending on SoC):
