This is one small chunk of work related to DT overlays for expansion boards. It would be good to have a way to expose #<list>-cells types of providers through a connector in a standard way. So we introduce a way to make "nexus" nodes for these types of properties to remap the consumer number space to the other side of the connector's number space. It's basically a copy of the interrupt nexus implementation, but without the address space matching design and interrupt-parent walking. The first patch implements a generic method to do this, and the second patch adds a unit test for it. The third patch is more of an example than anything else. It shows how we would modify frameworks to use the new API.
