Subject: [PATCH v7 4/7] arm64: dts: meson: g12: Add minimal thermal zone
Date: Fri, 4 Oct 2019 11:01:11 +0200 [thread overview]
Message-ID: <20191004090114.30694-5-glaroque@baylibre.com> (raw)
In-Reply-To: <20191004090114.30694-1-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)
