Subject: [v5 1/3] arm64: dts: mt8183: add thermal zone node
Date: Tue, 13 Oct 2020 18:23:56 +0800 [thread overview]
Message-ID: <20201013102358.22588-2-michael.kao@mediatek.com> (raw)
In-Reply-To: <20201013102358.22588-1-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.
