The new definitions will allow to support handling line-based metadata streams exposed by the sensor driver through an internal sink pad. While the changes have not yet been collected in the official linux-media tree, they're available in the 'metadata' branch of https://git.linuxtv.org/sailus/media_tree.git, at revision: 8d8fdc8a8809 ("media: Documentation: Add subdev configuration models, raw sensor model"). The patches are expected to land in Linux v6.13.
