13 VIDIOC_SUBDEV_ENUM_MBUS_CODE - Enumerate media bus formats
34 This call is used by the application to access the enumeration
42 Therefore, to enumerate media bus formats available at a given sub-device pad,
48 A successful call will return with the ``code`` field filled in
58 other pads of the sub-device, as well as on the current active links.
