+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.

Look at other bindings how this is done.

Thanks for review.
You're right.
In v3 I've made the clocks fixed per compatible rather than a flexible range, following the sdx75/glymur interconnect bindings.
