+description: |
+   RPMh 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.
