 13description: |
 14   RPMh interconnect providers support system bandwidth requirements through
 15   RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
 16   able to communicate with the BCM through the Resource State Coordinator (RSC)
 17   associated with each execution environment. Provider nodes must point to at
 18   least one RPMh device child node pertaining to their RSC and each provider
 19   can map to multiple RPMh resources.
