[PATCH v3 0/8] Add of-graph helpers to loop over endpoints and find ports by id

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

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 v2:
 - Fixed and simplified of_graph_get_port_by_id function
 - More acks

The previous version can be found here: https://lkml.org/lkml/2014/9/10/252

regards
Philipp
