---------------------------



What:	raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN

When:	November 2006

Why:	Deprecated in favour of the new ioctl-based rawiso interface, which is

	more efficient.  You should really be using libraw1394 for raw1394

	access anyway.

Who:	Jody McIntyre <scjody@modernduck.com>

When:	June 2007

Why:	Deprecated in favour of the more efficient and robust rawiso interface.

	Affected are applications which use the deprecated part of libraw1394

	(raw1394_iso_write, raw1394_start_iso_write, raw1394_start_iso_rcv,

	raw1394_stop_iso_rcv) or bypass	libraw1394.

Who:	Dan Dennedy <dan@dennedy.org>, Stefan Richter <stefanr@s5r6.in-berlin.de>



---------------------------



What:	dv1394 driver (CONFIG_IEEE1394_DV1394)

When:	June 2007

Why:	Replaced by raw1394 + userspace libraries, notably libiec61883.  This

	shift of application support has been indicated on www.linux1394.org

	and developers' mailinglists for quite some time.  Major applications

	have been converted, with the exception of ffmpeg and hence xine.

	Piped output of dvgrab2 is a partial equivalent to dv1394.

Who:	Dan Dennedy <dan@dennedy.org>, Stefan Richter <stefanr@s5r6.in-berlin.de>



---------------------------



What:	ieee1394 core's unused exports (CONFIG_IEEE1394_EXPORT_FULL_API)

When:	January 2007

Why:	There are no projects known to use these exported symbols, except

	dfg1394 (uses one symbol whose functionality is core-internal now).

Who:	Stefan Richter <stefanr@s5r6.in-berlin.de>



---------------------------



What:	ieee1394's *_oui sysfs attributes (CONFIG_IEEE1394_OUI_DB)

When:	January 2007

Files:	drivers/ieee1394/: oui.db, oui2c.sh

Why:	big size, little value

Who:	Stefan Richter <stefanr@s5r6.in-berlin.de>

	  This driver allows you to transmit and receive DV (digital video)

	  The user-space API for dv1394 is documented in dv1394.h.



	  To compile this driver as a module, say M here: the

	  module will be called dv1394.

	  The dv1394 driver will be removed from Linux in a future release.

	  Its functionality is now provided by raw1394 together with libraries

	  such as libiec61883.
