Subject: [PATCH v3 5/6] arm64: dts: amlogic: odroid-n2: add minimal thermal zone
Date: Tue,  6 Aug 2019 15:05:05 +0200	[thread overview]
Message-ID: <20190806130506.8753-6-glaroque@baylibre.com> (raw)
In-Reply-To: <20190806130506.8753-1-glaroque@baylibre.com>

Add minimal thermal zone for two temperature sensor
One is located close to the DDR and the other one is
located close to the PLLs (between the CPU and GPU)
