    Subject[PATCH 0/5] Add of-graph helpers to loop over endpoints and find ports by id
    Date
    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.

    regards
    Philipp
