Re: [PATCH 3/3] arm64: dts: exynos: Add thermal-zones dt node for Exynos5433 SoC

From: Lukasz Majewski
Date: Wed Mar 04 2015 - 05:53:51 EST


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.
