Subject: [v7,1/3] arm64: dts: mt8183: add thermal zone node
Date: Tue, 16 Mar 2021 15:01:42 +0800 [thread overview]
Message-ID: <20210316070144.28440-2-michael.kao@mediatek.com> (raw)
In-Reply-To: <20210316070144.28440-1-michael.kao@mediatek.com>
From: "michael.kao" <michael.kao@mediatek.com>
Add thermal zone node to Mediatek MT8183 dts file.
Evaluate the thermal zone every 500ms while not cooling
and every 100ms when passive cooling is performed.
