The commit d0a0ce3e77c795258d47f9163e92d5031d0c5221 ("thermal: exynos: Add missing definations and code cleanup") has removed setting of test MUX address value at TMU configuration setting. This field is not present on Exynos4210 and Exynos5 SoCs. However on Exynos4412 SoC it is required to set this field after reset because without it TMU shows maximal available temperature, which causes immediate platform shutdown.
