Hi, in theory, I'd like the first five patches to go in together through Grant's tree, but in practice that might not be necessary; changes in of_node reference counting are only relevant if CONFIG_OF_DYNAMIC is enabled. Since patch 2 depends on (or would trivially conflict with) 30e94a564d07 in the staging tree, it might be better to merge this one through staging. What do you think?
The three 'use for_each_endpoint_of_node macro in ...' patches can be resent later, separately. 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 v3: - Moved of_node_put for the break case after the loop in patch 1 and 8 - Rebased patch 2 on top of 30e94a564d07 (staging: imx-drm: Lines over 80 characters fixed.), which added a blank line in the function we remove, imx_drm_of_get_next_endpoint.
