Subject: [PATCH v5 6/6] arm64: dts: qcom: sc7180: Add opp-peak-kBps to GPU opp
Date:   Mon, 13 Jul 2020 18:11:46 +0530
Message-Id: <1594644106-22449-7-git-send-email-akhilpo@codeaurora.org>
In-Reply-To: <1594644106-22449-1-git-send-email-akhilpo@codeaurora.org>
References: <1594644106-22449-1-git-send-email-akhilpo@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Sharat Masetty <smasetty@codeaurora.org>

Add opp-peak-kBps bindings to the GPU opp table, listing the peak
GPU -> DDR bandwidth requirement for each opp level. This will be
used to scale the DDR bandwidth along with the GPU frequency dynamically.
