Subject: [PATCH v3 29/30] ARM: dts: sun8i: a83t: add thermal zone to A83T
Date: Thu, 30 Aug 2018 17:45:17 +0200	[thread overview]
Message-ID: <20180830154518.29507-30-embed3d@gmail.com> (raw)
In-Reply-To: <20180830154518.29507-1-embed3d@gmail.com>

This patch adds the thermal zones to the A83T. Sensor 0 is located
besides the cpu cluster 0. Sensor 1 is located besides cluster 1 and
sensor 2 is located besides in the gpu.
