Subject: [PATCH v2 11/11] arm64: qcom: dts: sm8650: add interconnect and opp-peak-kBps for GPU
Date: Tue, 19 Nov 2024 18:56:46 +0100 [thread overview]
Message-ID: <20241119-topic-sm8x50-gpu-bw-vote-v2-11-4deb87be2498@linaro.org> (raw)
In-Reply-To: <20241119-topic-sm8x50-gpu-bw-vote-v2-0-4deb87be2498@linaro.org>
Each GPU OPP requires a specific peak DDR bandwidth, let's add
those to each OPP and also the related interconnect path.
Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org>
