* [PATCH] BLOCK: Make USB storage depend on SCSI rather than selecting it [try #6]David Howells2006-09-301-3/+2
| | | | | | | | | This makes CONFIG_USB_STORAGE depend on CONFIG_SCSI rather than selecting it, as selecting it makes CONFIG_USB_STORAGE override the dependencies of SCSI, causing it to turn on even if they aren't all met.

* USB: g_file_storage: Set sense info Valid bit only when neededAlan Stern2006-09-281-1/+15
| | | | | | | | | | | Strictly speaking, the Valid bit in SCSI sense data is supposed to be set only when the Information field contains a valid number.

* OHCI: add auto-stop supportAlan Stern2006-09-283-84/+164
| | | | | | | | | | | | This patch (as790b) adds "autostop" support to ohci-hcd: the driver will automatically stop the host controller when no devices have been connected for at least one second. This feature is useful when the USB autosuspend facility isn't available, such as when CONFIG_USB_SUSPEND hasn't been set.

* OHCI: remove existing autosuspend codeAlan Stern2006-09-281-44/+6
| | | | | | | | | | | | The autosuspend technique used by ohci-hcd doesn't mesh well with the newer USB core autosuspend code. This patch (as789) removes ohci-hcd's autosuspend support. Now the driver will be usable, but it won't automatically go into a low-power state when no devices are connected. That's for a later patch.

* USB: allow both root-hub interrupts and pollingAlan Stern2006-09-281-2/+1
| | | | | | | | | | Originally I didn't think any host controller driver would ever use interrupts and polling at the same time, but it turns out ohci-hcd wants to do exactly that.

* USB: create new workqueue thread for USB autosuspendAlan Stern2006-09-283-8/+46
| | | | | | | | | | | | | | This patch (as787) creates a new workqueue thread to handle delayed USB autosuspend requests. Previously the code used keventd. However it turns out that the hub driver's suspend routine calls flush_scheduled_work(), making it a poor candidate for running in keventd (the call immediately deadlocks). The solution is to use a new thread instead of keventd. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: Pegasus driver failing for ADMtek 8515 network devicePetko Manolov2006-09-281-7/+11
| | | | | | | | | | | | | | | | | | | | | Address http://bugzilla.kernel.org/show_bug.cgi?id=7126 Attempting to read the ethernet ID directly from the eeprom somehow confuses ADM8515. Subsequent read requests to either the eeprom or the MII fail as well. Didn't dig much deeper, though. For example ADM8513 does not experience this problem. I used the fact that at power up the device is reading its ID automatically (not true for older Pegasus based devices) and put it in the Ethernet ID registers. So now the driver uses get_registers() instead of read_eprom_word() if the device is Pegasus_II based one. Tested it with all (Pegasus and Pegasus_II) gadgets i have and everything seems ok.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | This patch(as785) forces the PM core to resume a root hub after a power loss during system sleep.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

* | cypress_m8: use usb_fill_int_urb where appropriateMike Isely2006-09-271-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* | cypress_m8: use appropriate URB polling intervalMike Isely2006-09-271-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
