2012-03-08usb: cdc-wdm: adding usb_cdc_wdm_register subdriver supportBjørn Mork
This driver can be used as a subdriver of another USB driver, allowing it to export a Device Managment interface consisting of a single interrupt endpoint with no dedicated USB interface. Some devices provide a Device Management function combined with a wwan function in a single USB interface having three endpoints (bulk in/out + interrupt). If the interrupt endpoint is used exclusively for DM notifications, then this driver can support that as a subdriver provided that the wwan driver calls the appropriate entry points on probe, suspend, resume, pre_reset, post_reset and disconnect. The main driver must have full control over all interface related settings, including the needs_remote_wakeup flag. A manage_power function must be provided by the main driver. A manage_power stub doing direct flag manipulation is used in normal driver mode.

2012-03-08usb: cdc-wdm: adding list lookup indirectionBjørn Mork
Register all interfaces handled by this driver in a list, getting rid of the dependency on usb_set_intfdata. This allows further generalization and simplification of the probe/create functions. This is needed to decouple wdm_open from the driver owning the interface, and it also allows us to share all the code in wdm_create with drivers unable to do usb_set_intfdata.

2012-03-02usb/core: remove "always" from usb_unlink_urb() kernel doc entrySebastian Andrzej Siewior
The kernel doc entry for usb_unlink_urb() contains the phrase "This request is always asynchronous.". The "always" leads to the assumption that the ->complete() callback is not called from within usb_unlink_urb(). This is not true. The HCD is allowed to call the ->complete() from within ->urb_dequeue() if it is appropriate for the hardware. This patch updates the kernel doc so usb-device driver authors make sure to drop all locks (and make sure it is okay to drop them) which are acquired by the complete callback before calling usb_unlink_urb().

2012-03-02Allocate correct size (portably) in drivers/usb/gadget/f_midi.c::f_midi_bind()Jesper Juhl
As the coverity checker puts it: "Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc" and then casting the return value to "struct usb_descriptor_header **" is suspicious. ... In this particular case sizeof(struct usb_descriptor_header **) happens to be equal to sizeof(struct usb_descriptor_header *), but this is not a portable assumption." I believe we really do intend to use 'sizeof(*midi_function)' here, so this patch makes that change.

2012-03-02usb: cp210x: Update to support CP2105 and multiple interface devicesPreston Fick
This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by: Preston Fick <preston.fick@silabs.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: dwc3: changes for v3.4 merge window Here are the changes for v3.4 merge window. It includes a new glue layer for Samsung's Exynos platform, a simplification of memory management on DWC3 driver by using dev_xxx functions, a few optimizations to IRQ handling by dropping memcpy() and using bitshifts, a fix for TI's OMAP5430 TX Fifo Allocation, two fixes on USB2 test mode implementation (one on debugfs and one on ep0), and several minor changes such as whitespace cleanups, simplification of a few parts of the code, decreasing a long delay to something a bit saner, dropping a header which was included twice and so on. The highlight on this merge is the support for Samsung's Exynos platform, increasing the number of different users for this driver to three. Note that Samsung Exynos glue layer will only compile on platforms which provide implementation for the clk API for now. Once Samsung supports pm_runtime, that limitation can be dropped from the Makefile. Conflicts: drivers/usb/dwc3/gadget.c

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: Gadget: changes for 3.4 This merge is rather big. Here's what it contains: For am5536udc we have just simple coding style fixes. Nothing that has any potential to cause any issues going forward. With mv_udc, there's only one single change removing an unneeded NULL check. at91_udc also only saw a single change this merge window, and that's only removing a duplicated header. The Renesas controller has a few more involved changes. Support for SUDMAC was added, there's now a special handling of IRQ resources for when the IRQ line is shared between Renesas controller and SUDMAC, we also had a bug fix where Renesas controller would sleep in atomic context while doing DMA transfers from a tasklet. There were also a set of minor cleanups. The FSL UDC also had a scheduling in atomic context bug fix, but that's all. Thanks to Sebastian, the dummy_hcd now works better than ever with support for scatterlists and streams. Sebastian also added SuperSpeed descriptors to the serial gadgets. The highlight on this merge is the addition of a generic API for mapping and unmapping usb_requests. This will avoid code duplication on all UDC controllers and also kills all the defines for DMA_ADDR_INVALID which UDC controllers sprinkled around. A few of the UDC controllers were already converted to use this new API. Conflicts: drivers/usb/dwc3/gadget.c

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: MUSB changes for 3.4 Here are a set of changes to the MUSB driver. In summary we have a patch making modules behave better, there's a fix on debugfs' error path, a small change removing an unnecessary pm_runtime call on musb_shutdown() and a fix to relesect the endpoint in Interrupt context. This last patch is needed because we must drop musb's lock when calling request->complete() and that could cause problems if another thread queues a request and ends up changing MUSB_INDEX register.
