| 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.
