Hi,

I addressed Andrzej's comments on of_graph_get_port_by_id() and added
Mathieu's ack to the first patch. Also I missed the omap2-dss init code
last time around. For the first patch, I'd like to get an ack for the rcar-du
and omap2-dss changes so this can 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 v6:
 - Fixed of_graph_get_port_by_id to handle the optional 'ports' node
   and synchronize documentation and parameter names in the process.
 - Added omap2-dss to the list of updated of_graph_get_next_endpoint
   users in the first patch.
 - Added Mathieu's ack to the first patch.

The previous version can be found here: https://lkml.org/lkml/2014/12/22/220

regards
Philipp
