Subject: Re: [PATCH 3/3] arm64: dts: exynos: Add thermal-zones dt node for
Exynos5433 SoC
Hi Chanwoo,
> This patch adds the thermal-zones devicetree node for Exynos5433 SoC.
> The thermal-zones has five thermal-zones and then each thermal-zone
> contains each thermal-sensor to monitor the temperature of own IP.
> The {atlas0|apollo}_ thermal zone have the eight trip-points for
> interrupt method to detect the over-temperature.
