Hi Chanwoo,
> This patch adds the TMU (Thermal Management Unit) sensor devicetree
> node for Exynos5433. The Exynos5433 includes the five temperature
> sensors as following:
> - two temperature sensor for Cortex-A57 (ATLAS)
> - one temperature sensor for Cortex-A53 (APOLLO)
> - one temperature sensor for G3D IP
> - one temperature sensor for ISP IP
