Subject: [PATCH 14/18] thermal: exynos: move trips setting to
exynos_tmu_initialize()
* Add dummy exynos4210_tmu_set_trip_hyst() helper.
* Add ->tmu_set_trip_temp and ->tmu_set_trip_hyst methods to struct
exynos_tmu_data and set them in exynos_map_dt_data().
* Move trips setting to exynos_tmu_initialize().
There should be no functional changes caused by this patch.
