[PATCH 0/5] Iterate of_graph endpoints using a for_each_... style macro

Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> · Fri, 4 Jul 2014 10:30:41 +0200

Hi,

decrementing the reference count of the previous endpoint node parameter to
of_graph_get_next_endpoint allows to wrap the function in a for_each macro.

This series removes the remaining workaround in imx-drm, adds the macro
for_each_endpoint_of_node, and switches the current users to it. It builds
upon Russell's patches:
 "drm: add of_graph endpoint helper to find possible CRTCs" and
 "imx-drm: convert imx-drm to use the generic DRM OF helper"

regards
Philipp
