Subject: [PATCH v5 4/6] arm64: dts: qcom: SDM845: Enable GPU DDR bw scaling
Date: Mon, 13 Jul 2020 18:11:44 +0530 [thread overview]
Message-ID: <1594644106-22449-5-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1594644106-22449-1-git-send-email-akhilpo@codeaurora.org>
From: Sharat Masetty <smasetty@codeaurora.org>
This patch adds the interconnects property for the gpu node and the
opp-peak-kBps property to the opps of the gpu opp table. This should
help enable DDR bandwidth scaling dynamically and proportionally to the
GPU frequency.
