+description: |
+   SDM845 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 reside within
+   an RPMh device node pertaining to their RSC and each provider maps to a
+   single RPMh resource.
