USB: add USB_VENDOR_AND_INTERFACE_INFO() macro

2012-09-12T02:36:54Z

commit d81a5d1956731c453b85c141458d4ff5d6cc5366 upstream. A lot of Broadcom Bluetooth devices provides vendor specific interface class and we are getting flooded by patches adding new device support. This change will help us enable support for any other Broadcom with vendor specific device that arrives in the future. Only the product id changes for those devices, so this macro would be perfect for us: { USB_VENDOR_AND_INTERFACE_INFO(0x0a5c, 0xff, 0x01, 0x01) } Signed-off-by: Marcel Holtmann Signed-off-by: Gustavo Padovan Acked-by: Henrik Rydberg Signed-off-by: Greg Kroah-Hartman Signed-off-by: Ben Hutchings

usb: fix number of mapped SG DMA entries

2012-01-12T19:29:43Z

commit bc677d5b64644c399cd3db6a905453e611f402ab upstream. Add a new field num_mapped_sgs to struct urb so that we have a place to store the number of mapped entries and can also retain the original value of entries in num_sgs. Previously, usb_hcd_map_urb_for_dma() would overwrite this with the number of mapped entries, which would break dma_unmap_sg() because it requires the original number of entries. This fixes warnings like the following when using USB storage devices: ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:902 check_unmap+0x4e4/0x695() ehci_hcd 0000:00:12.2: DMA-API: device driver frees DMA sg list with different entry count [map count=4] [unmap count=1] Modules linked in: ohci_hcd ehci_hcd Pid: 0, comm: kworker/0:1 Not tainted 3.2.0-rc2+ #319 Call Trace: [] warn_slowpath_common+0x80/0x98 [] warn_slowpath_fmt+0x41/0x43 [] check_unmap+0x4e4/0x695 [] ? trace_hardirqs_off+0xd/0xf [] ? _raw_spin_unlock_irqrestore+0x33/0x50 [] debug_dma_unmap_sg+0xeb/0x117 [] usb_hcd_unmap_urb_for_dma+0x71/0x188 [] unmap_urb_for_dma+0x20/0x22 [] usb_hcd_giveback_urb+0x5d/0xc0 [] ehci_urb_done+0xf7/0x10c [ehci_hcd] [] qh_completions+0x429/0x4bd [ehci_hcd] [] ehci_work+0x95/0x9c0 [ehci_hcd] ... ---[ end trace f29ac88a5a48c580 ]--- Mapped at: [] debug_dma_map_sg+0x45/0x139 [] usb_hcd_map_urb_for_dma+0x22e/0x478 [] usb_hcd_submit_urb+0x63f/0x6fa [] usb_submit_urb+0x2c7/0x2de [] usb_sg_wait+0x55/0x161 Signed-off-by: Clemens Ladisch Signed-off-by: Greg Kroah-Hartman

include: convert various register fcns to macros to avoid include chaining

2011-10-31T23:32:32Z

The original implementations reference THIS_MODULE in an inline. We could include , but it is better to avoid chaining. Fortunately someone else already thought of this, and made a similar inline into a #define in for device_schedule_callback(), [see commit 523ded71de0] so follow that precedent here. Also bubble up any __must_check that were used on the prev. wrapper inline functions up one to the real __register functions, to preserve any prev. sanity checks that were used in those instances.

xHCI: set USB2 hardware LPM

2011-09-26T22:51:10Z

If the device pass the USB2 software LPM and the host supports hardware LPM, enable hardware LPM for the device to let the host decide when to put the link into lower power state. If hardware LPM is enabled for a port and driver wants to put it into suspend, it must first disable hardware LPM, resume the port into U0, and then suspend the port.

usbcore: get BOS descriptor set

2011-09-26T22:51:08Z

This commit gets BOS(Binary Device Object Store) descriptor set for Super Speed devices and High Speed devices which support BOS descriptor. BOS descriptor is used to report additional USB device-level capabilities that are not reported via the Device descriptor. By getting BOS descriptor set, driver can check device's device-level capability such as LPM capability. Signed-off-by: Andiry Xu Signed-off-by: Sarah Sharp Signed-off-by: Greg Kroah-Hartman

USB: use usb_endpoint_maxp() instead of le16_to_cpu()

USB: documentation update for the pre_reset method

2011-04-30T00:24:29Z

This patch (as1459) updates the documentation for the pre_reset method in struct usb_driver. When a driver is notified of an impending reset, it must cancel all outstanding I/O and not start any new I/O until it has been notified that the reset is complete. As far as I know, most existing drivers that implement pre_reset do this now. The major exceptions appear to be the SpeedTouch and CDC-WDM drivers.
