2010-10-11ieee1394: remove the old IEEE 1394 driver stackStefan Richter
The drivers - ohci1394 (controller driver) - ieee1394 (core) - dv1394, raw1394, video1394 (userspace ABI) - eth1394, sbp2 (protocol drivers) are replaced by - firewire-ohci (controller driver) - firewire-core (core and userspace ABI) - firewire-net, firewire-sbp2 (protocol drivers) which are more featureful, better performing, and more secure than the older drivers; all with a smaller and more modern code base. The driver firedtv in drivers/media/dvb/firewire/ contains backends to both ieee1394 and firewire-core. Its ieee1394 backend code can be removed in an independent commit; firedtv as-is builds and works fine without ieee1394. The driver pcilynx (an incomplete controller driver) is deleted without replacement since PCILynx cards are extremely rare. Owners of these cards use them with the stand-alone bus sniffer driver nosy instead. The drivers nosy and init_ohci1394_dma which do not interact with either of the two IEEE 1394 stacks are not affected by the ieee1394 subsystem removal. There are still some issues with the newer firewire subsystem compared to the older one: - The rare and quirky controllers ALi M52xx, Apple UniNorth v1, NVIDIA NForce2 are even less well supported by firewire-ohci than by ohci1394. I am looking into the M52xx issue. - The experimental firewire-net is reportedly less stable than its experimental cousin eth1394. - Audio playback of a certain group of audio devices (ones based on DICE chipset with EAP; supported by prerelease FFADO code) does not work yet. This issue is still under investigation. - There were some ieee1394 based out-of-the-mainline drivers. Of them, only lisight, an audio driver for iSight webcams, seems still useful. Work is underway to reimplement it on top of firewire-core. All these remainig issues are minor; they should not stand in the way of overall better user experience of IEEE 1394 on Linux, together with a reduction in support efforts and maintenance burden. The coexistence of two IEEE 1394 kernel driver stacks in the mainline since 2.6.22 shall end now, as announced earlier this year. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2008-07-14ieee1394: video1394: reorder module init, prepare BKL removalStefan Richter
This prepares video1394 for removal of the BKL (big kernel lock): It allows video1394_open() to be called while video1394_init_module() is still in progress. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-07-10ieee1394: remove old isochronous ABIStefan Richter
Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

2006-12-07ieee1394: remove unused struct member from highlevel APIStefan Richter
struct hpsb_highlevel's struct module *owner is neither used by the IEEE 1394 core nor set by any of the in-tree drivers or the two out-of-tree highlevel drivers I know about (dfg1394, mem1394) --- nor is this member documented. An unscheduled removal seems acceptable. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
