Subject: [PATCH 6/6] dt-bindings: drm/msm/gpu: Document gpu opp table
Date: Thu, 14 May 2020 16:24:19 +0530 [thread overview]
Message-ID: <1589453659-27581-7-git-send-email-smasetty@codeaurora.org> (raw)
In-Reply-To: <1589453659-27581-1-git-send-email-smasetty@codeaurora.org>
Update documentation to list the gpu opp table bindings including the
newly added "opp-peak-kBps" needed for GPU-DDR bandwidth scaling.
