+Subject: [PATCH] media: uapi: v4l2-core: Add sensor ancillary data
+ V4L2 foucc type.
+
+Add V4L2_META_FMT_SENSOR_DATA format 4CC.
+
+This new format will be used by the BCM2835 Unicam device to return
+out camera sensor embedded data.

++Sensor Ancillary Metadata
++
++Description
++===========
++
++This format describes ancillary data generated by a camera sensor and
++transmitted over a stream on the camera bus. Sensor vendors generally have their
++own custom format for this ancillary data. Some vendors follow a generic
++CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
++<https://mipi.org/specifications/csi-2>`_
++
++The size of the embedded buffer is defined as a single line with a pixel width
++width specified in bytes. This is obtained by a call to the
++:c:type:`VIDIOC_SUBDEV_G_FMT` ioctl on the sensor subdevice where the ``pad``
++field in :c:type:`v4l2_subdev_format` is set to 1.  Note that this size is fixed
++and cannot be modified with a call to :c:type:`VIDIOC_SUBDEV_S_FMT`.
