Subject: [PATCH v4 2/2] arm64: dts: qcom: sc7280: Add gpu thermal zone cooling support
Date: Wed, 11 Aug 2021 19:48:36 +0530	[thread overview]
Message-ID: <20210811194758.v4.2.Iea8318d85a23f0167fd523ea85df5630147649f9@changeid> (raw)
In-Reply-To: <1628691516-33624-1-git-send-email-akhilpo@codeaurora.org>

From: Manaf Meethalavalappu Pallikunhi <manafm@codeaurora.org>

Add cooling-cells property and the cooling maps for the gpu thermal
zones to support GPU thermal cooling.
