Subject: [PATCH v2 3/8] arm64: dts: mt8183: Add #cooling-cells to CPU nodes
Date: Fri, 10 May 2019 21:27:01 +0800
Message-ID: <1557494826-6044-4-git-send-email-michael.kao@mediatek.com> (raw)
In-Reply-To: <1557494826-6044-1-git-send-email-michael.kao@mediatek.com>

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