[PATCH v3 0/3] OF phandle nexus support + GPIO nexus

Show all headers | View raw

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.

Changes since v2:
 * Picked up Linus' ack on the gpio core patch
 * Made const stack arrays static (Rob Herring)
 * Used of_property_read_u32() instead of open coding (Rob Herring)

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()
