Subject: [PATCH v2 2/3] arm64: dts: qcom: sc7180: Add gpu cooling support
Date: Mon, 19 Oct 2020 18:44:27 +0530 [thread overview]
Message-ID: <1603113268-21161-2-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1603113268-21161-1-git-send-email-akhilpo@codeaurora.org>
Add cooling-cells property and the cooling maps for the gpu tzones
to support GPU cooling.
Signed-off-by: Akhil P Oommen <akhilpo@codeaurora.org>
---
The thermal policy should be set as 'step_wise' for gpu tzones from
the userspace during boot up.
