[PATCH v8 0/3] Add of-graph helpers to loop over endpoints and find ports by id

From: Philipp Zabel
Date: Mon Feb 23 2015 - 05:54:49 EST


Since there now is a merge conflict in imx-drm-core, I've rebased the series
onto v4.0-rc1. Also a new driver touched by this change appeared, so the first
patch now includes a fix for am437x-vfpe, too. I'd be happy to get an ack for

This series converts all existing users of of_graph_get_next_endpoint that pass
a non-NULL prev argument to the function and decrement its refcount themselves
to stop doing that. The of_node_put is moved into of_graph_get_next_endpoint
This allows to add a for_each_endpoint_of_node helper macro to loop over all
endpoints in a device tree node.

Changes since v8:
- Rebased onto v4.0-rc1
- Added fix to am437x-vpfe
