Subject: [PATCH v6 0/3] Add of-graph helpers to loop over endpoints and find ports by id
Date: Mon, 22 Dec 2014 16:11:28 +0100

Hi,

next try for v3.20. After the merge window we have a few new users of
of_graph_get_next_endpoint, could I please get some acks from the respective
maintainers for this to go in through Grant's tree?

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
instead.
This allows to add a for_each_endpoint_of_node helper macro to loop over all
endpoints in a device tree node.

Changes since v5:
 - Rebased onto v3.19-rc1
 - Added new users of of_graph_get_next_endpoint, coresight and
   drm/rcar-du. There's also rockchip, but the driver already doesn't
   decrement the prev node's reference count.
 - Dropped the "use for_each_endpoint_of_node macro" patches,
   I'll add the new users and resend them separately.

The previous version can be found here: https://lkml.org/lkml/2014/9/29/529

regards
Philipp
