| 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. |
