H A Dinterconnect.txt4 The purpose of this document is to define a common set of generic interconnect
8 = interconnect providers =
10 The interconnect provider binding is intended to represent the interconnect
11 controllers in the system. Each provider registers a set of interconnect
12 nodes, which expose the interconnect related capabilities of the interconnect
14 etc. The consumer drivers set constraints on interconnect path (or endpoints)
15 depending on the use case. Interconnect providers can also be interconnect
