Subject: [RFC PATCH 2/2] arm64: dts: qcom: sa8775p: Add CPU and LLCC BWMON
Add CPU and LLCC BWMON nodes and their corresponding opp tables for
SA8775p SoC.
SA8775p has two cpu clusters, with each cluster having a set of
CPU-to-LLCC BWMON registers. Consequently, there are two sets of
CPU-to-LLCC registers.
