It is not necessary to powerdown the ports on ehci_pci_reinit() when the chip reset already did that. Removing this saves 20ms during restart after poweroff paths (which OLPC uses a lot). To ensure driver startup then behaves consistently, force a reset during driver startup. (Not doing this was an accident of some previous changes to the init sequence.) Make the corresponding change in the PS3 support. It's not clear what ehci-fsl should do here; it has similar code to the PS3. Signed-off-by:

Ueagle-atm driver load DSP firmware in function, which is running from common workqueue. In some (error) circumstances loading firmware may sleep for long periods (even 60 seconds, depending on timeout). This block keyboard driver, which also use common workqueue. To fix problem use custom workqueue in ueagle-atm. Signed-off-by:

Support for Devolo and Elsa chipsets. These chipsets have no information about ADSL annex (line type) encoded in USB descriptors. Driver try to get this information from USB VID and PID or it can be explicitly set by the user through module parameter. Thanks to Johann Hanne, whose make most of this patch. Signed-off-by:

Add support to newest chipset of eagle family. It is compatible with older chipsets at USB level. However DSP firmware and CMVs (Configuration and Management Variables) have different format of data and are sent/received by different way. Signed-off-by:

This patch (as962) cleans up some code I forgot to remove earlier in the isp116x and sl811 HCDs. There is no longer any need to check for unlink-during-submit; it can't happen since the endpoint queues are now under the protection of the HCD-private spinlock. Signed-off-by:

If submit fails, slab hits a BUG() because of a double kfree. The today's lesson is, you cannot just slap USB_FREE_BUFFER on code without adjusting the error paths. The patch is made bigger by opportunistic refactoring. Signed-Off-By:

Setup packet must be visible in virtual space. There's absolutely no good reason to implement any kind of zero-copy transfer of 8 bytes, and the documentation in usb.h is explicit about it. So, drop DMA remapping. Signed-off-by:

Add a mutex to protect the ->statusbuf. Not really an issue, because CUPS is single-threaded when it talks to the printer, but I feel safer this way. This should be deadlock-free, but I kept this as a separate patch in case someone ends running a git bisect. Signed-off-by:

This patch (as957) makes some minor cleanups to the g_file_storage driver: Update the copyright date and version string; Uniformize the logging macros for the gadget and the LUNs; Remove "inline" markers -- nowadays we rely on the compiler to decide which routines are best inlined; Use the print_hex_dump() library routines; Remove some unnecessary assignments within conditionals and fix some close-brace indenting levels; Fix some column-80 violations.

This patch (as955) prevents the interface-related sysfs files and endpoint pseudo-devices from being deleted and recreated when a call to usb_set_interface() specifies the current altsetting. Since the altsetting doesn't get changed, there's no need to do anything. Furthermore, avoiding changes to the endpoint devices will be necessary in the future. This code is called from usb_reset_device(), which gets invoked for reset-resume processing, but upcoming changes to the PM and driver cores will make it impossible to register devices while a suspend/resume transition is in progress. Since we don't need to re-register those endpoint devices anyhow, it's best to skip the whole thing. Signed-off-by:

This patch (as954) implements a suggestion of David Brownell's. Now the host controller drivers are responsible for linking and unlinking URBs to/from their endpoint queues. This eliminates the possiblity of strange situations where usbcore thinks an URB is linked but the HCD thinks it isn't. It also means HCDs no longer have to check for URBs being dequeued before they were fully enqueued. In addition to the core changes, this requires changing every host controller driver and the root-hub URB handler. For the most part the required changes are fairly small; drivers have to call usb_hcd_link_urb_to_ep() in their urb_enqueue method, usb_hcd_check_unlink_urb() in their urb_dequeue method, and usb_hcd_unlink_urb_from_ep() before giving URBs back. A few HCDs make matters more complicated by the way they split up the flow of control. In addition some method interfaces get changed. The endpoint argument for urb_enqueue is now redundant so it is removed. The unlink status is required by usb_hcd_check_unlink_urb(), so it has been added to urb_dequeue. Signed-off-by:

These USB API functions will do the full authorization/deauthorization to be used for a device. When authorized we effectively allow a configuration to be set. Reverse that when deauthorized. Effectively this means that we have to clean all the configuration descriptors on deauthorize and reload them when we authorized. We could do without throwing them out for wired devices, but for wireless, we can read them only after authenticating, and thus, when authorizing an authenticated device we would need to read them. So to simplify, always release them on deauthorize(), re-read them on authorize(). Also fix leak reported by Ragner Magalhaes; in usb_deauthorize_device(), bNumConfigurations was being set to zero before the for loop, and thus the different raw descriptors where never being freed.

This patch takes hub.c:usb_new_device() and splits it in three parts: - The actual actions of adding a new device (quirk detection, announcement and autoresume tracking) - Actual discovery and probing of the configuration and interfaces (split into __usb_configure_device()) - Configuration of the On-the-go parameters (split into __usb_configure_device_otg()). The fundamental reasons for doing this split are clarity (smaller functions are easier to maintain) and to allow part of the code to be reused when authorizing devices to connect. When a device is authorized connection, we need to run through the hoops we didn't run when it was connected but not authorized, which is basically parsing the configurations and probing them. usb_configure_device() will do that for us.
