22 * 2003/02/24 show registers in sysfs (Kevin Brosius)
23 *
24 * 2002/09/03 get rid of ed hashtables, rework periodic scheduling and

27 * 2002/06/09 SA-1111 support (Christopher Hoover)
28 * 2002/06/01 remember frame when HC won't see EDs any more; use that info
29 * to fix urb unlink races caused by interrupt latency assumptions;
30 * minor ED field and function naming updates
31 * 2002/01/18 package as a patch for 2.5.3; this should match the
32 * 2.4.17 kernel modulo some bugs being fixed.
33 *
34 * 2001/10/18 merge pmac cleanup (Benjamin Herrenschmidt) and bugfixes
35 * from post-2.4.5 patches.
36 * 2001/09/20 URB_ZERO_PACKET support; hcca_dma portability, OPTi warning
37 * 2001/09/07 match PCI PM changes, errnos from Linus' tree
38 * 2001/05/05 fork 2.4.5 version into "hcd" framework, cleanup, simplify;
39 * pbook pci quirks gone (please fix pbook pci sw!) (db)
40 *
41 * 2001/04/08 Identify version on module load (gb)

47 * 2000/09/26 fixed races in removing the private portion of the urb
48 * 2000/09/07 disable bulk and control lists when unlinking the last
49 * endpoint descriptor in order to avoid unrecoverable errors on
50 * the Lucent chips. (rwc@sgi)
51 * 2000/08/29 use bandwidth claiming hooks (thanks Randy!), fix some
52 * urb unlink probs, indentation fixes
53 * 2000/08/11 various oops fixes mostly affecting iso and cleanup from
54 * device unplugs.
55 * 2000/06/28 use PCI hotplug framework, for better power management
56 * and for Cardbus support (David Brownell)
57 * 2000/earlier: fixes for NEC/Lucent chips; suspend/resume handling
