12description: |
13  RPMh interconnect providers support system bandwidth requirements through
14  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
15  able to communicate with the BCM through the Resource State Coordinator (RSC)
16  associated with each execution environment. Provider nodes must point to at
17  least one RPMh device child node pertaining to their RSC and each provider
18  can map to multiple RPMh resources.
