Merge branch 'ieee1394-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6
* 'ieee1394-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6: ieee1394: remove the old IEEE 1394 driver stack ieee1394: move init_ohci1394_dma to drivers/firewire/ Fix trivial change/delete conflict: drivers/ieee1394/eth1394.c is getting removed, but was modified by the networking merge.

- New application development should use raw1394 + userspace libraries
- instead, notably libiec61883 which is functionally equivalent.

+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/dv1394/* were character device files, one for each FireWire
+ controller and for NTSC and PAL respectively, from which DV data
+ could be received by read() or transmitted by write(). A few
+ ioctl()s allowed limited control.
+ This special-purpose interface has been superseded by libraw1394 +
+ libiec61883 which are functionally equivalent, support HDV, and
+ transparently work on top of the newer firewire kernel drivers.

+Date: May 2010 (scheduled), finally removed in kernel v2.6.37
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/raw1394 was a character device file that allowed low-level
+ access to FireWire buses. Its major drawbacks were its inability
+ to implement sensible device security policies, and its low level
+ of abstraction that required userspace clients do duplicate much
+ of the kernel's ieee1394 core functionality.
+ Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
+ firewire-core.

-What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
-Date: June 2007 (scheduled), removed in kernel v2.6.23
-Contact: linux1394-devel@lists.sourceforge.net
-Description:
- The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
- been deprecated for quite some time. They are very inefficient as they
- come with high interrupt load and several layers of callbacks for each
- packet. Because of these deficiencies, the video1394 and dv1394 drivers
- and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
-
-Users:
- libraw1394 users via the long deprecated API raw1394_iso_write,
- raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
-
- libdc1394, which optionally uses these old libraw1394 calls
- alternatively to the more efficient video1394 ABI

+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ /dev/video1394/* were character device files, one for each FireWire

+ to use raw1394 + libraw1394 too because video1394 did not provide
