+Sensor Ancillary Metadata Formats
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This section lists ancillary data generated by a camera sensor and
+transmitted over a stream on the camera bus.
+
+The following table lists the existing sensor ancillary metadata formats:

+.. _v4l2-mbus-pixelcode-sensor-metadata:
+
+.. tabularcolumns:: |p{8.0cm}|p{1.4cm}|p{7.7cm}|

+ - MEDIA_BUS_FMT_SENSOR_DATA
+ - 0x7001
+ - Sensor vendor specific ancillary metadata. Some vendors follow a generic
+ CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
