-+ * EHCI hc_driver implementation ... experimental, incomplete.
-+ * Based on the final 1.0 register interface specification.
-+ *
-+ * USB 2.0 shows up in upcoming www.pcmcia.org technology.
-+ * First was PCMCIA, like ISA; then CardBus, which is PCI.
-+ * Next comes "CardBay", using USB 2.0 signals.
-+ *
-+ * Contains additional contributions by Brad Hards, Rory Bolt, and others.
-+ * Special thanks to Intel and VIA for providing host controllers to
-+ * test this driver on, and Cypress (including In-System Design) for
-+ * providing early devices for those host controllers to talk to!
-+ *
-+ * HISTORY:
-+ *
-+ * 2004-05-10 Root hub and PCI suspend/resume support; remote wakeup. (db)
-+ * 2004-02-24 Replace pci_* with generic dma_* API calls (dsaxena@plexity.net)
-+ * 2003-12-29 Rewritten high speed iso transfer support (by Michal Sojka,
-+ * <sojkam@centrum.cz>, updates by DB).
-+ *
-+ * 2002-11-29 Correct handling for hw async_next register.
-+ * 2002-08-06 Handling for bulk and interrupt transfers is mostly shared;
-+ * only scheduling is different, no arbitrary limitations.
-+ * 2002-07-25 Sanity check PCI reads, mostly for better cardbus support,
-+ * clean up HC run state handshaking.
-+ * 2002-05-24 Preliminary FS/LS interrupts, using scheduling shortcuts
-+ * 2002-05-11 Clear TT errors for FS/LS ctrl/bulk. Fill in some other
-+ * missing pieces: enabling 64bit dma, handoff from BIOS/SMM.
-+ * 2002-05-07 Some error path cleanups to report better errors; wmb();
-+ * use non-CVS version id; better iso bandwidth claim.
-+ * 2002-04-19 Control/bulk/interrupt submit no longer uses giveback() on
-+ * errors in submit path. Bugfixes to interrupt scheduling/processing.
-+ * 2002-03-05 Initial high-speed ISO support; reduce ITD memory; shift
-+ * more checking to generic hcd framework (db). Make it work with
-+ * Philips EHCI; reduce PCI traffic; shorten IRQ path (Rory Bolt).
-+ * 2002-01-14 Minor cleanup; version synch.
-+ * 2002-01-08 Fix roothub handoff of FS/LS to companion controllers.
-+ * 2002-01-04 Control/Bulk queuing behaves.
-+ *
-+ * 2001-12-12 Initial patch version for Linux 2.5.1 kernel.
-+ * 2001-June Works with usb-storage and NEC EHCI on 2.4
