Subject: [PATCH v6 4/7] arm64: dts: meson: g12: Add minimal thermal zone
Date: Fri, 27 Sep 2019 20:43:49 +0200	[thread overview]
Message-ID: <20190927184352.28759-5-glaroque@baylibre.com> (raw)
In-Reply-To: <20190927184352.28759-1-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)

Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
