I don't think Georgi maintains this device. It's maintainer of device,
not the subsystem.
Ok, Will update the maintainer.

+ 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.

This if: clause should be merged with the one earlier.
Ok, understood.

Please keep the order like in example-schema, so required: goes before

Sure, will update this.

Thanks,
