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)
