Subject: [PATCH v3 25/30] ARM: dts: sun8i: h3: add thermal zone to H3
Date: Thu, 30 Aug 2018 17:45:13 +0200
Message-Id: <20180830154518.29507-26-embed3d@gmail.com>
In-Reply-To: <20180830154518.29507-1-embed3d@gmail.com>
References: <20180830154518.29507-1-embed3d@gmail.com>
List-ID: <linux-iio@vger.kernel.org>

This patch adds the thermal zones to the H3. We have only one sensor and
that is placed in the cpu.
