+ decode_vbi_line: video decoders that support sliced VBI need to implement

+ then parses the sliced VBI data and sets the other fields in the
+ struct accordingly. The pointer p is updated to point to the start of
+ the payload which can be copied verbatim into the data field of the
+ v4l2_sliced_vbi_data struct. If no valid VBI data was found, then the
+ type field is set to 0 on return.
+
+ s_vbi_data: used to generate VBI signals on a video signal.
+ v4l2_sliced_vbi_data is filled with the data packets that should be
+ output. Note that if you set the line field to 0, then that VBI signal
+ is disabled. If no valid VBI data was found, then the type field is
+ set to 0 on return.
+
+ g_vbi_data: used to obtain the sliced VBI packet from a readback register.
+ Not all video decoders support this. If no data is available because
+ the readback register contains invalid or erroneous data -EIO is
+ returned. Note that you must fill in the 'id' member and the 'field'
+ member (to determine whether CC data from the first or second field
+ should be obtained).
+
+ s_std_output: set v4l2_std_id for video OUTPUT devices. This is ignored by
+ video input devices.
+
+ s_crystal_freq: sets the frequency of the crystal used to generate the
+ clocks in Hz. An extra flags field allows device specific configuration
+ regarding clock frequency dividers, etc. If not used, then set flags
+ to 0. If the frequency is not supported, then -EINVAL is returned.
+
+ g_input_status: get input status. Same as the status field in the v4l2_input
+ struct.
