10 - Hector Martin <marcan@marcan.st>
13 Apple SoCs (e.g. M1) have a per-cpu-cluster DVFS controller that is part of
14 the cluster management register block. This binding uses the standard
15 operating-points-v2 table to define the CPU performance states, with the
16 opp-level property specifying the hardware p-state index for that level.
