All drivers use custom notifications, in particular when source changes.
The bridge only has to map the subdev that sends it to whatever video node it

vb2_buffer_done() already allows STATE_QUEUED, but currently only when not
streaming. It is useful to allow it while streaming as well, as this makes
it possible for drivers to requeue buffers while waiting for a stable
video signal.

This makes it easier for the bridge driver to just passthrough such
