Subject: [PATCH v4 3/3] dt-bindings: drm/msm/gpu: Add cooling device support
Date: Thu, 29 Oct 2020 13:37:21 +0530	[thread overview]
Message-ID: <1603958841-20233-3-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1603958841-20233-1-git-send-email-akhilpo@codeaurora.org>

Add cooling device support to gpu. A cooling device is bound to a
thermal zone to allow thermal mitigation.
