+description: |
+ The Bus Clock Manager (BCM) is a dedicated hardware accelerator that manages
+ shared system resources by aggregating requests from multiple Resource State
+ Coordinators (RSC). Interconnect providers are able to vote for aggregated
+ thresholds values from consumers by communicating through their respective
+ RSCs.
