scripts: sphinx-build-wrapper: get rid of uapi/media Makefile

2025-08-29T21:54:43+00:00

Now that kernel-include directive supports parsing data structs directly, we can finally get rid of the horrible hack we added to support parsing media uAPI symbols. As a side effect, Documentation/output doesn't have anymore media auto-generated .rst files on it.

media: videodev2: Add flag to unconditionally enumerate pixel formats

2024-10-12T17:56:16+00:00

When the index is ORed with V4L2_FMTDESC_FLAG_ENUM_ALL the driver clears the flag and enumerate all the possible formats, ignoring any limitations from the current configuration. Drivers which do not support this flag yet always return an EINVAL.

media: v4l: Support line-based metadata capture

2024-04-29T12:56:36+00:00

Many camera sensors, among other devices, transmit embedded data and image data for each CSI-2 frame. This embedded data typically contains register configuration of the sensor that has been used to capture the image data of the same frame. The embedded data is received by the CSI-2 receiver and has the same properties as the image data, including that it is line based: it has width, height and bytesperline (stride). Add these fields to struct v4l2_meta_format and document them. Also add V4L2_FMT_FLAG_META_LINE_BASED to tell a given format is line-based i.e. these fields of struct v4l2_meta_format are valid for it.
