This patch (as1197) fixes an error introduced recently. Since a significant number of devices can't handle Set-Interface requests, we no longer call usb_set_interface() when a driver unbinds from an interface, provided the interface is already in altsetting 0. However the interface still does get disabled, and the call to usb_set_interface() was the only thing re-enabling it. Since the interface doesn't get re-enabled, further attempts to use it fail. So the patch adds a call to usb_enable_interface() when a driver unbinds and the interface is in altsetting 0. For this to work right, the interface's endpoints have to be re-enabled but their toggles have to be left alone. Therefore an additional argument is added to usb_enable_endpoint() and usb_enable_interface(), a flag indicating whether or not the endpoint toggles should be reset. This is a forward-ported version of a patch which fixes Bugzilla #12301. Signed-off-by:

This patch (as1195) eliminates a potential problem identified by Oliver Neukum. When a driver queues an asynchronous Set-Config request using usb_driver_set_configuration(), the request should be cancelled if userspace changes the configuration first. The patch introduces a linked list of pending async Set-Config requests, and uses it to invalidate the requests for a particular device whenever that device's configuration is set. Signed-off-by:

This patch (as1193b) enables wakeup during initialization for all PCI host controllers, and it removes some code (and comments!) that are no longer needed now that the PCI core automatically initializes wakeup settings for all new devices. The idea is that the bus should initialize wakeup, and the bus glue or controller driver should enable it. Signed-off-by:

This patch (as1192) rearranges the USB PCI host controller suspend and resume and resume routines: Use pci_wake_from_d3() for enabling and disabling wakeup, instead of pci_enable_wake(). Carry out the actual state change while interrupts are disabled. Change the order of the preparations to agree with the general recommendation for PCI devices, instead of messing around with the wakeup settings while the device is in D3. In .suspend: Call the underlying driver to disable IRQ generation; pci_wake_from_d3(device_may_wakeup()); pci_disable_device(); In .suspend_late: pci_save_state(); pci_set_power_state(D3hot); (for PPC_PMAC) Disable ASIC clocks In .resume_early: (for PPC_PMAC) Enable ASIC clocks pci_set_power_state(D0); pci_restore_state(); In .resume: pci_enable_device(); pci_set_master(); pci_wake_from_d3(0); Call the underlying driver to reenable IRQ generation Add the necessary .suspend_late and .resume_early method pointers to the PCI host controller drivers.

This patch (as1194) makes usb-storage set the CAPACITY_HEURISTICS flag for all devices made by Nokia, Nikon, or Motorola. These companies seem to include the READ CAPACITY bug in all of their devices. Since cell phones and digital cameras rely on flash storage, which always has an even number of sectors, setting CAPACITY_HEURISTICS shouldn't cause any problems. Not even if the companies wise up and start making devices without the bug. A large number of unusual_devs entries are now unnecessary, so the patch removes them. Signed-off-by:

This patch (as1190) makes usb-storage's "quirks=" module parameter writable, so that users can add entries for their devices at runtime with no need to reboot or reload usb-storage. New codes are added for the SANE_SENSE, CAPACITY_HEURISTICS, and CAPACITY_OK flags. Signed-off-by:

This patch (as1189b) adds some hacks to usb-storage for dealing with the growing problems involving bad capacity values and last-sector accesses: A new flag, US_FL_CAPACITY_OK, is created to indicate that the device is known to report its capacity correctly. An unusual_devs entry for Linux's own File-backed Storage Gadget is added with this flag set, since g_file_storage always reports the correct capacity and since the capacity need not be even (it is determined by the size of the backing file). An entry in unusual_devs.h which has only the CAPACITY_OK flag set shouldn't prejudice libusual, since the device will work perfectly well with either usb-storage or ub. So a new macro, COMPLIANT_DEV, is added to let libusual know about these entries. When a last-sector access succeeds and the total number of sectors is odd (the unexpected case, in which guessing that the number is even might cause trouble), a WARN is triggered. The kerneloops.org project will collect these warnings, allowing us to add CAPACITY_OK flags for the devices in question before implementing the default-to-even heuristic. If users want to prevent the stack dump produced by the WARN, they can disable the hack by adding an unusual_devs entry for their device with the CAPACITY_OK flag. When a last-sector access fails three times in a row and neither the FIX_CAPACITY nor the CAPACITY_OK flag is set, we assume the last-sector bug is present. We replace the existing status and sense data with values that will cause the SCSI core to fail the access immediately rather than retry indefinitely. This should fix the difficulties people have been having with Nokia phones. Signed-off-by:

There is no need to disable port 1 on ISP1761. That port could be used as an OTG port which would require a different init sequence. However we don't have OTG support (yet) so we can use it as a normal USB port. This patch allows port 1 to be used a normal Port on the ISP1761. Signed-off-by:

Many newer Option mobile broadband devices initially provide a usb-storage "driver CD" device that's pretty useless on Linux since any software on it most likely wouldn't be compatible with your kernel or distro anyway. Thus, by default just kill the driver CD device by sending the SCSI 'rezero' command, but allow override of the default behavior via usb-storage module parameter so users can keep the ZeroCD device if they really want to. Inspired by the Sierra TruInstall patch. Signed-off-by:

This patch (as1185) makes usbcore take advantage of the bus notifications sent out by the driver core. Now we can create all our device and interface attribute files before the device or interface uevent is broadcast. A side effect is that we no longer create the endpoint "pseudo" devices at the same time as a device or interface is registered -- it seems like a bad idea to try registering an endpoint before the registration of its parent is complete. So the routines for creating and removing endpoint devices have been split out and renamed, and they are called explicitly when needed. A new bitflag is used for keeping track of whether or not the interface's endpoint devices have been created, since (just as with the interface attributes) they vary with the altsetting and hence can be changed at random times.

The DPCM subdriver is a little peculiar, in that it's meant to support devices where LUN 0 is Compact Flash and uses the CB transport whereas LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't really a transport in itself; it's more like a demultiplexer. Much of the DPCM code is part of the SDDR09 subdriver already, and the remaining part is fairly small. This patch (as1182) moves that extra piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is the Kconfig entry for DPCM support; it is now listed as part of the SDDR09 entry. In order to make sure that the semantics are the same as before, each unusual_devs entry for DPCM is now present twice: once with DPCM support if SDDR09 is configured (as before), and once with the SINGLE_LUN flag and CB support otherwise.

Contains fixes so probe on x86 PCI runs, apparently I'm first to try this. Several fixes to memory access to probe host scratch register. Previously would bug check on chip_addr var used uninitialized. Scratch reg write failed in one instance due to 16-bit initial access mode, so added "& 0x0000ffff" to the readl as fix. Includes some general cleanup - remove global vars, organize memory map resource use. Signed-off-by:

This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by:

This patch (as1178) uses the new round_jiffies_up_relative() routine for setting the autosuspend delayed_work timer. It's appropriate since we don't care too much about the exact length of the delay, but we don't want it to be too short (rounded down). Signed-off-by:

gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

This moves the isp1301-omap driver from the drivers/i2c/chips directory (which will be shrinking) into a new drivers/usb/otg directory (which will grow, with more drivers and utilities). Note that OTG infrastructure needs to be initialized before either host or peripheral side USB support, and may be needed before for pure host or pure peripheral configurations. Signed-off-by:
