Subject: [PATCH v6 9/9] arm64: dts: exynos: Add thermal-zones dt node for
Exynos5433 SoC
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.
