Is this needed?
If this is to be part of the media controller, then I expect to see a call
to v4l2_m2m_register_media_controller() somewhere.
Yes, I agree there should be a call to
v4l2_m2m_register_media_controller(). This driver does not connect with
any of the imx-media entities, but calling it will at least make the
mem2mem output/capture device entities (and processing entity) visible
in the media graph.
Philipp, can you pick/squash the following from my media-tree github fork?
6fa05f5170 ("media: imx: mem2mem: Add missing media-device header")
d355bf8b15 ("media: imx: Add missing unregister and remove of mem2mem
device")
6787a50cdc ("media: imx: mem2mem: Register with media control")
