Subject: [PATCH v3 5/6] arm64: dts: amlogic: odroid-n2: add minimal thermal zone
Date:   Tue,  6 Aug 2019 15:05:05 +0200
Message-Id: <20190806130506.8753-6-glaroque@baylibre.com>
In-Reply-To: <20190806130506.8753-1-glaroque@baylibre.com>
References: <20190806130506.8753-1-glaroque@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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)
