Subject: [PATCH v4 4/6] arm64: dts: meson: sei510: Add minimal thermal zone
Date: Thu, 22 Aug 2019 00:24:19 +0200	[thread overview]
Message-ID: <20190821222421.30242-5-glaroque@baylibre.com> (raw)
In-Reply-To: <20190821222421.30242-1-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)
