Subject[PATCH v5 0/6] Add of-graph helpers to loop over endpoints and find ports by id
Date
Hi,

now the first three patches of the previous series are combined into one. This
patch touches of, media, and staging. Since it is rebased onto Grant's tree, it
now trivially conflicts with 30e94a564d07 (staging: imx-drm: Lines over 80
characters fixed.)

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.
The third of patch adds a of_graph_get_port_by_id function to retrieve a port
by its known port id from the device tree.

Finally, the last three patches convert functions in drm_of.c and imx-drm-core.c
to use the for_each_endpoint_of_node macro instead of of_graph_get_next_endpoint.

Changes since v4:
- Combined patches 1-3 into one

The previous version can be found here: https://lkml.org/lkml/2014/9/29/78

regards
Philipp
