would it be more proper to use "Samsung thermal drivers" or "Samsung
Exynos thermal drivers" instead?

sorry I know few about arm,
could you tell me the difference between
CONFIG_ARCH_EXYNOS4/CONFIG_ARCH_EXYNOS5 and CONFIG_PLAT_SAMSUNG please,
I do not see the dependency between these in Kconfig file?
