2006-09-27USB: Airprime driver improvements to allow full speed EvDO transfersAndy Gay
Adapted from an earlier patch by Greg KH <gregkh@suse.de>. That patch added multiple read urbs and larger transfer buffers to allow data transfers at full EvDO speed. This version includes additional device IDs and fixes a memory leak in the transfer buffer allocation. Some (maybe all?) of the supported devices present multiple bulk endpoints, the additional EPs can be used for control and status functions, This version allocates 3 EPs by default, that can be changed using the 'endpoints' module parameter. Tested with Sierra Wireless EM5625 and MC5720 embedded modules. Device ID (0x0c88, 0x17da) for the Kyocera Wireless KPC650/Passport was added but is not yet tested.

2006-09-27USB: EHCI update VIA workaroundDavid Brownell
This revamps handling of the hardware "async advance" IRQ, and its watchdog timer. Basically it dis-entangles that important timeout from the others, simplifying the associated state and code to make it more robust. This reportedly improves behavior of EHCI on some systems with VIA chips, and AFAIK won't affect non-VIA hardware. VIA systems need this code to recover from silcon bugs whereby the "async advance" IRQ isn't issued.

2006-09-27USB: force root hub resume after power lossAlan Stern
This patch(as785) forces the PM core to resume a root hub after a power loss during system sleep. If the root hub had been suspended before the system sleep then normally the PM core would not resume it afterward. Without this resume, various sorts of wakeup events (like port change events) can get lost. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-27USB: ohci_usb can oops on shutdownPete Zaitcev
When ohci-hcd is shutting down (for rmmod or PC-card removal), there is a window when the device is shut down, HC communication area (->hcca) is freed, but the core has not called "free_irq" yet. If another device triggers a shared interrupt in this window, we oops when trying to access the freed ->hcca. This patch removes the window by calling free_irq before ->hcca is freed. The patch is tested at the PC hotplug test rig at Stratus, and with rmmod by Rafael Wysocki.

2006-09-27USB: Dealias -110 code (more complete)Pete Zaitcev
The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.

2006-09-27USB: u132-hcd: host controller driver for ELAN U132 adapterTony Olech
This "u132-hcd" module is one half of the "driver" for ELAN's U132 which is a USB to CardBus OHCI controller adapter. This module needs the "ftdi-elan" module in order to communicate to CardBus OHCI controller inserted into the U132 adapter. When the "ftdi-elan" module detects a supported CardBus OHCI controller in the U132 adapter it loads this "u132-hcd" module. Upon a successful device probe() the single workqueue is started up which does all the processing of commands from the USB core that implement the host controller. The workqueue maintains the urb queues and issues commands via the functions exported by the "ftdi-elan" module. Each such command will result in a callback. Note that the "ftdi-elan" module is a USB client driver. Note that this "u132-hcd" module is a (cut-down OHCI) host controller. Thus we have a topology with the parent of a host controller being a USB client! This really stresses the USB subsystem semaphore/mutex handling in the module removal.

2006-09-27USB: ftdi-elan: client driver for ELAN Uxxx adaptersTony Olech
This "ftdi-elan" module is one half of the "driver" for ELAN's Uxxx series adapters which are USB to PCMCIA CardBus adapters. Currently only the U132 adapter is available and it's module is called "u132-hcd". When the USB hot plug subsystem detects a Uxxx series adapter it should load this module. Upon a successful device probe() the jtag device file interface is created and the status workqueue started up. The jtag device file interface exists for the purpose of updating the firmware in the Uxxx series adapter, but as yet it had never been used. The status workqueue initializes the Uxxx and then sits there polling the Uxxx until a supported PCMCIA CardBus device is detected it will start the command and respond workqueues and then load the module that handles the device. This will initially be only the u132-hcd module. The status workqueue then just polls the Uxxx looking for card ejects. The command and respond workqueues implement a command sequencer for communicating with the firmware on the other side of the FTDI chip in the Uxxx. This "ftdi-elan" module exports some functions to interface with the sequencer. Note that this module is a USB client driver. Note that the "u132-hcd" module is a (cut-down OHCI) host controller. Thus we have a topology with the parent of a host controller being a USB client! This really stresses the USB subsystem semaphore/mutex handling in the module removal.

2006-09-27cypress_m8: implement graceful failure handlingMike Isely
When receiving a fatal error from the USB core, e.g. EILSEQ (which can happen if the polling interval is too short), fail gracefully. Previously the driver would fill the log with useless error messages or (more alarmingly) silently spin forever trying to write updated control information to the device. This change implements a new flag which if cleared indicates that the driver has failed. The flag will be set on initialization, cleared on fatal errors, and anything else that touches the USB port in the driver will abort if the flag is clear. When the flag is cleared, a message will be logged indicating that the driver has failed. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-27cypress_m8: improve control endpoint error handlingMike Isely
Fix usb core function error return checks to look for negative errno values, not positive errno values. This bug had rendered those checks useless. Also remove attempted error recovery on control endpoints for EPIPE - with control endpoints EPIPE does not indicate a halted endpoint so trying to recover with usb_clear_halt() is not the correct action.

2006-09-27cypress_m8: use usb_fill_int_urb where appropriateMike Isely
Rather than directly filling in URB fields, it's safer to use usb_fill_int_urb(). This improves robustness of the driver; URB changes in the future will not go uninitialized here. That point not withstanding, this driver should at least be self-consistent. Either use usb_fill_int_urb() everywhere or don't bother with it all.

2006-09-27cypress_m8: use appropriate URB polling intervalMike Isely
The polling interval for the device can't always be 1msec. If it is too quick, the device can fail causing a fatal (to the driver) EILSEQ error from the USB core. The actual correct value is reported by the device as part of its configuration data, so use that value as the default. On a DeLorme Earthmate for example, the device reports that it wants a 6msec interval. As part of this fix, the "interval" module option has been fixed as well; the device's default can be overridden by specifying interval=<value> as a module option.

2006-09-27USB: fix root-hub resume when CONFIG_USB_SUSPEND is not setAlan Stern
This patch (as786) removes a redundant test and fixes a problem involving repeated system sleeps when CONFIG_USB_SUSPEND is not set. During the first wakeup, the root hub's dev.power.power_state.event field doesn't get updated, causing it not to be suspended during the second sleep transition.

2006-09-27usbcore: remove usb_suspend_root_hubAlan Stern
This patch (as740) removes the existing support for autosuspend of root hubs. That support fit in rather awkwardly with the rest of usbcore and it was used only by ohci-hcd.

2006-09-27usbcore: add autosuspend/autoresume infrastructureAlan Stern
This patch (as739) adds the basic infrastructure for USB autosuspend and autoresume. The main features are: PM usage counters added to struct usb_device and struct usb_interface, indicating whether it's okay to autosuspend them or they are currently in use. Flag added to usb_device indicating whether the current suspend/resume operation originated from outside or as an autosuspend/autoresume. Flag added to usb_driver indicating whether the driver supports autosuspend. If not, no device bound to the driver will be autosuspended. Mutex added to usb_device for protecting PM operations. Unlike the device semaphore, the locking rule for the pm_mutex is that you must acquire the locks going _up_ the device tree. New routines handling autosuspend/autoresume requests for interfaces and devices. Suspend and resume requests are propagated up the device tree (but not outside the USB subsystem). work_struct added to usb_device, for carrying out delayed autosuspend requests. Autoresume added (and autosuspend prevented) during probe and disconnect. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-27usbcore: store each usb_device's level in the treeAlan Stern
This patch (as778) adds a field to struct usb_device to store the device's level in the USB tree. In itself this number isn't really important.

2006-09-27USB: net2280: update dma buffer allocationDavid Brownell
This updates the code handling dma-coherent buffer allocations, basically reusing code from the musb_hdrc driver. Instead of trying to work around two significant limitations of the dma framework (memory wastage for buffers smaller than a page, and inconsistency between calling context requirements for allocation and free) this just works around one of them (the latter). So count this as two steps forward (bugfixes: the latter issue could cause errors on some platforms, and some MIPS changes broke code for the former), and one step back (increasing cross-platform memory wastage). Plus linelength and whitespace fixes; and minor data segment shrinkage. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-09-27usbcore: trim down usb_bus structureAlan Stern
As part of the ongoing program to flatten out the HCD bus-glue layer, this patch (as771b) eliminates the hcpriv, release, and kref fields from struct usb_bus. hcpriv and release were not being used for anything worthwhile, and kref has been moved into the enclosing usb_hcd structure. Along with those changes, the patch gets rid of usb_bus_get and usb_bus_put, replacing them with usb_get_hcd and usb_put_hcd. The one interesting aspect is that the dev_set_drvdata call was removed from usb_put_hcd, where it clearly doesn't belong. This means the driver private data won't get reset to NULL. It shouldn't cause any problems, since the private data is undefined when no driver is bound. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
