Merge tag 'of-graph-for-4.0' of git://git.pengutronix.de/git/pza/linux into for-next
Pull of-graph helpers from Philipp Zabel: of: Add of-graph helpers to loop over endpoints and find ports by id This series converts of_graph_get_next_endpoint to decrement the refcount of the passed prev parameter. This allows to add a for_each_endpoint_of_node helper macro to loop over all endpoints in a device tree node. The of_graph_get_port_by_id function is added to retrieve a port by its known port id (contained in the reg property) from the device tree.
