2009-07-12USB: EHCI: use the new clear_tt_buffer interfaceAlan Stern
This patch (as1256) changes ehci-hcd and all the other drivers in the EHCI family to make use of the new clear_tt_buffer callbacks. When a Clear-TT-Buffer request is in progress for a QH, the QH is not allowed to be linked into the async schedule until the request is finished. At that time, if there are any URBs queued for the QH, it is linked into the async schedule.

2009-06-15USB: EHCI: update toggle state for linked QHsAlan Stern
This patch (as1245) fixes a bug in ehci-hcd. When an URB is queued for an endpoint whose QH is already in the LINKED state, the QH doesn't get refreshed. As a result, if usb_clear_halt() was called during the time that the QH was linked but idle, the data toggle value in the QH doesn't get reset. The symptom is that after a clear_halt, data gets lost and transfers time out. This problem is starting to show up now because the "ehci-hcd unlink speedups" patch causes QHs with no queued URBs to remain linked for a suitable time. The patch utilizes the new endpoint_reset mechanism to fix the problem. When an endpoint is reset, the new method forcibly unlinks the QH (if necessary) and safely updates the toggle value. This allows qh_update() to be simplified and avoids using usb_device's toggle bits in a rather unintuitive way.

2008-05-29USB: EHCI: suppress unwanted error messagesAlan Stern
This patch (as1096) fixes an annoying problem: When a full-speed or low-speed device is plugged into an EHCI controller, it fails to enumerate at high speed and then is handed over to the companion controller. But usbcore logs a misleading and unwanted error message when the high-speed enumeration fails. The patch adds a new HCD method, port_handed_over, which asks whether a port has been handed over to a companion controller. If it has, the error message is suppressed.

2008-05-29USB: EHCI: fix up root-hub TT messAlan Stern
This patch (as1095) cleans up the HCD glue and several of the EHCI bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it means the same thing as the hcd->has_tt flag, so it is removed and the other flag used in its place. Some of the bus-glue files didn't get the relinquish_port method added to their hc_driver structures. Although that routine currently doesn't do anything for controllers with an integrated TT, in the future it might. So the patch adds it where it is missing. Lastly, some of the bus-glue files have erroneous entries for their hc_driver's suspend and resume methods. These method pointers are specific to PCI and shouldn't be used otherwise. (The patch also includes an invisible whitespace fix.) Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: David Brownell <dbrownell@users.sourceforge.net>
2008-04-24USB: ehci minor SOC bus glue fixesDavid Brownell
Various minor fixes to some SOC bus glue for EHCI: - Remove a bogus copyright (by "me"!) which someone added to the FSL driver, and an irrelevant comment. - Un-break MODULE_ALIAS() directives after platform_bus hotplugging acquired a backwards-incompatible change. (Which didn't fix ANY of the in-tree drivers it prevented from hotplugging -- sigh.) - Remove some bogus assignments of platform_bus_type; that's done by the platform_bus code. - Add some FIXMEs for drivers with that pointless two-level idiom for probe() and remove() routines. ("Obfuscation" is a non-goal.) That should help avoid future bus glue which copies that idiom.
