   SC7180 interconnect providers support system bandwidth requirements through

   RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is

   able to communicate with the BCM through the Resource State Coordinator (RSC)

   associated with each execution environment. Provider nodes must point to at

   least one RPMh device child node pertaining to their RSC and each provider

   can map to multiple RPMh resources.
