2013-04-19USB: ti_usb_3410_5052: kill custom closing_waitJohan Hovold
Kill custom closing_wait implementation and let the tty-layer handle it instead. Note that the port drain-delay is set to three characters to keep the 20ms delay after wait_until_sent at low baudrates (1200 baud) during close.

2013-04-17usbfs: Always allow ctrl requests with USB_RECIP_ENDPOINT on the ctrl epHans de Goede
When usbfs receives a ctrl-request from userspace it calls check_ctrlrecip, which for a request with USB_RECIP_ENDPOINT tries to map this to an interface to see if this interface is claimed, except for ctrl-requests with a type of USB_TYPE_VENDOR. When trying to use this device: http://www.akaipro.com/eiepro redirected to a Windows vm running on qemu on top of Linux. The windows driver makes a ctrl-req with USB_TYPE_CLASS and USB_RECIP_ENDPOINT with index 0, and the mapping of the endpoint (0) to the interface fails since ep 0 is the ctrl endpoint and thus never is part of an interface. This patch fixes this ctrl-req failing by skipping the checkintf call for USB_RECIP_ENDPOINT ctrl-reqs on the ctrl endpoint.

2013-04-08USB: EHCI: make ehci-orion a separate driverManjunath Goudar
Separate the Orion host controller driver from ehci-hcd host code into its own driver module because of following reason. With the multiplatform changes in arm-soc tree, it becomes possible to enable the mvebu platform (which uses ehci-orion) at the same time as other platforms that require a conflicting EHCI bus glue. At the moment, this results in a warning like drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable] and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the orion bus glue. An earlier version of this patch was included in 3.9 but caused a regression there, which has subsequently been fixed. While we are here, use the opportunity to disabiguate the two Marvell EHCI controller implementations in Kconfig. In V4 (arnd): - Improve Kconfig text In V3: - More detail provided in commit message regarding this patch. - Replaced hcd_name string "ehci-orion" into "orion-ehci". - MODULE_LICENSE is GPL v2. - In ehci_init_driver calling second argument passed as NULL instead of ehci_orion_overrides because ehci_orion_overrides is removed. In V2: - Tegra patch related changes removed from this patch.

2013-04-08xhci - clarify compliance mode debug messagesTony Camuso
There are no functional changes in this patch. However, because the compliance mode timer can be deleted in more than one function, it seemed expedient to include the function name in the debug strings. Also limited the use of capitals to the first word in the compliance mode debug messages, except after a function name where all words start with lower case, in keeping with the style prevalent elsewhere in xhci.c.

tty_port_tty_get might return a tty which is NULL. But it is dereferenced unconditionally in edge_send. Stop dereferencing that by sending usb_serial_port pointer around.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.10 merge window Here is the big Gadget & PHY pull request. Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.
