2009-01-27USB: musb uses endpoint functionsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-01-27USB: fix char-device disconnect handlingAlan Stern
This patch (as1198) fixes a conceptual bug: Somewhere along the line we managed to confuse USB class devices with USB char devices. As a result, the code to send a disconnect signal to userspace would not be built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were disabled. The usb_fs_classdev_common_remove() routine has been renamed to usbdev_remove() and it is now called whenever any USB device is removed, not just when a class device is unregistered. The notifier registration and unregistration calls are no longer conditionally compiled. And since the common removal code will always be called as part of the char device interface, there's no need to call it again as part of the usbfs interface; thus the invocation of usb_fs_classdev_common_remove() has been taken out of usbfs_remove_device().

2009-01-27USB: Fix suspend-resume of PCI USB controllersRafael J. Wysocki
Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703 (USB: fix up suspend and resume for PCI host controllers) attempted to fix the suspend-resume of PCI USB controllers, but unfortunately it did that incorrectly and interrupts are left enabled by the USB controllers' ->suspend_late() callback as a result. This leads to serious problems during suspend which are very difficult to debug. Fix the issue by removing the ->suspend_late() callback of PCI USB controllers and moving the code from there to the ->suspend() callback executed with interrupts enabled. Additionally, make the ->resume() callback of PCI USB controllers execute pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the full power state (PCI_D0). Signed-off-by: Rafael J.

2009-01-27USB: don't enable wakeup by default for PCI host controllersAlan Stern
This patch (as1199) changes the initial wakeup settings for PCI USB host controllers. The controllers are marked as capable of waking the system, but wakeup is not enabled by default. It turns out that enabling wakeup for USB host controllers has a lot of bad consequences. As the simplest example, if a USB mouse or keyboard is unplugged immediately after the computer is put to sleep, the unplug will cause the system to wake back up again! We are better off marking them as wakeup-capable and leaving wakeup disabled. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Reported-by: Rafael J.

2009-01-27USB: fix toggle mismatch in disable_endpoint pathsAlan Stern
This patch (as1200) finishes some fixes that were left incomplete by an earlier patch. Although nobody has addressed this issue in the past, it turns out that we need to distinguish between two different modes of disabling and enabling endpoints. In one mode only the data structures in usbcore are affected, and in the other mode the host controller and device hardware states are affected as well. The earlier patch added an extra argument to the routines in the enable_endpoint pathways to reflect this difference. This patch adds corresponding arguments to the disable_endpoint pathways. Without this change, the endpoint toggle state can get out of sync between the host and the device. The exact mechanism depends on the details of the host controller (whether or not it stores its own copy of the toggle values).

2009-01-07USB: re-enable interface after driver unbindsAlan Stern
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.

New codes are added for the SANE_SENSE, CAPACITY_HEURISTICS, and CAPACITY_OK flags. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-01-07USB: storage: add last-sector hacksAlan Stern
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.

Add driver for the high speed USB-OTG transceiver in TI's TWL4030 family of chips. Given this and various other pending patches, OMAP3 hardware like that from beagleboard.org, gumstix.com (Overo), and openpandora.org should now have basic USB host and peripheral connectivity with mainline kernels. Ditto for less widely-available boards.

2009-01-07USB: isp1760: don't auto disable Port1 on ISP1761Thomas Hommel
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.

2009-01-07USB: unusual dev for Option N.V. ZeroCD modemsDan Williams
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.

2009-01-07USB: utilize the bus notifiersAlan Stern
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.
