+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.
