Subject[PATCH v2 08/10] arm64: dts: qcom: sc8280xp: Set up L3 scaling
Date
Add the L3 interconnect path to all CPUs and define the bandwidth
requirements for all opp entries across sc8280xp and sa8540p.

The values are based on the tables reported by the hardware, distributed
such that each value is the largest value, lower than the cluster
frequency.
