Subject: [PATCH v4 7/7] arm64: dts: qcom: sc7180: Add opp-peak-kBps to GPU opp
From: Sharat Masetty <smasetty@...eaurora.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.
