With Hans proposed changes that you've already acked, I think the proposal is ok, except for one detail: > 4. Format enumeration > ---------------------------------- > struct v4l2_fmtdesc, used for format enumeration, does include the > v4l2_buf_type > enum as well, so the new types can be handled properly here as well. > For drivers supporting both versions of the API, 1-plane formats should be > returned for multiplanar buffer types as well, for consistency.

If the userspace is asking for multi-planar types, the driver should return just the multi-planar formats. If the userspace wants to know about both, it will just call for both types of formats.
