Subject: [PATCH 3/4] arm64: dts: mt8183: Add #cooling-cells to CPU nodes
Date: Wed, 14 Aug 2019 18:06:48 +0800
Message-ID: <1565777209-21869-4-git-send-email-michael.kao@mediatek.com> (raw)
In-Reply-To: <1565777209-21869-1-git-send-email-michael.kao@mediatek.com>

From: "michael.kao" <michael.kao@mediatek.com>

The #cooling-cells property needs to be specified to allow a CPU
to be used as cooling device.
