Subject[PATCHv2 0/3] OF phandle nexus support + GPIO nexus
Date
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.

I wasn't certain what more to document, but I

Changes since v1:
* Addition of optional pass-thru parameter
* Reduction of strings passed to 1 instead of 3 (or 4 now)
* Updated gpio patch for the new function signature
* Updated test-case for new funciton signature and pass-thru parameter
* Updated kernel-doc to be correct and highlighted difference between
this API and of_parse_phandle_with_args()

Stephen Boyd (3):
of: Support parsing phandle argument lists through a nexus node
of: unittest: Add phandle remapping test
gpio: Support gpio nexus dt bindings
