Diego Herranz 2dc0194c1d doc: usb: Fix typo in gadget_multi documentation
It tries to "match" drivers for each interface (not "much").

Reilly Grant d883f52e1f usb: devio: Add ioctl to disallow detaching kernel USB drivers.
The new USBDEVFS_DROP_PRIVILEGES ioctl allows a process to voluntarily
relinquish the ability to issue other ioctls that may interfere with
other processes and drivers that have claimed an interface on the
device.

This commit also includes a simple utility to be able to test the
ioctl, located at Documentation/usb/usbdevfs-drop-permissions.c

Example (with qemu-kvm's input device):

    $ lsusb
    ...
    Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd

    $ usb-devices
    ...
    C:  #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
    I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=02 Driver=usbhid

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    OK: privileges dropped!
    Available options:
    [0] Exit now
    [1] Reset device. Should fail if device is in use
    [2] Claim 4 interfaces. Should succeed where not in use
    [3] Narrow interface permission mask
    Which option shall I run?: 1
    ERROR: USBDEVFS_RESET failed! (1 - Operation not permitted)
    Which test shall I run next?: 2
    ERROR claiming if 0 (1 - Operation not permitted)
    ERROR claiming if 1 (1 - Operation not permitted)
    ERROR claiming if 2 (1 - Operation not permitted)
    ERROR claiming if 3 (1 - Operation not permitted)
    Which test shall I run next?: 0

After unbinding usbhid:

    $ usb-devices
    ...
    I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=02 Driver=(none)

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    ...
    Which option shall I run?: 2
    OK: claimed if 0
    ERROR claiming if 1 (1 - Operation not permitted)
    ERROR claiming if 2 (1 - Operation not permitted)
    ERROR claiming if 3 (1 - Operation not permitted)
    Which test shall I run next?: 1
    OK: USBDEVFS_RESET succeeded
    Which test shall I run next?: 0

After unbinding usbhid and restricting the mask:

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    ...
    Which option shall I run?: 3
    Insert new mask: 0
    OK: privileges dropped!

Greg Kroah-Hartman 3d0712deb0 usb changes for v4.6 merge window
This is almost all under drivers/usb/dwc2/. Many
 changes to the host side implementation of dwc2 have
 been done by Douglas Anderson.
 
 We also have USB 3.1 support added to the Gadget
 Framework and, because of that work, dwc3 got
 support to Synopsys new DWC_usb31 IP core.
 
 Other than these 2 important series, we also have
 the usual collection of non-critical fixes,
 Documentation updates, and minor changes all over
 the place.

Christian Lamparter a6d6fc2b67 usbip: move usbip_protocol.txt to Documentation
The usbip_protocol.txt, a document which describes usbip's
inner workings is currently located in the projects source
directory (drivers/usb/usbip/...). This patch moves it to
Documentation/usb.

This discussion was brought up by Guy Harris [0] during the
review of the USBIP dissector I wrote. For anyone interested:
support is available with the latest wireshark master/dev tree.
Simply select a packet from the usbip's tcp-stream you are
intrested on and select the USBIP as the protocol in the
"Decode As" dialog box [1].

Lu Baolu bf5ce5bf3c usb: core: lpm: fix usb3_hardware_lpm sysfs node
Commit 655fe4effe ("usbcore: add sysfs support to xHCI usb3
hardware LPM") introduced usb3_hardware_lpm sysfs node. This
doesn't show the correct status of USB3 U1 and U2 LPM status.

This patch fixes this by replacing usb3_hardware_lpm with two
nodes, usb3_hardware_lpm_u1 (for U1) and usb3_hardware_lpm_u2
(for U2), and recording the U1/U2 LPM status in right places.

This patch should be back-ported to kernels as old as 4.3,
that contains Commit 655fe4effe ("usbcore: add sysfs support
to xHCI usb3 hardware LPM").

New support for Allwinne SoC on the MUSB driver has been added to the list of

 this will be great for distros.
 
 DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
 tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
 maxpacket size transfers are > 512 bytes.
 
 Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
 now required to set these flags up when adding endpoints to the framework.
 
 Other than these, we have the usual set of miscelaneous cleanups and minor

Andrzej Pietrasiewicz d6d22922d9 usb: gadget: rndis: remove the limit of available rndis connections
RNDIS function has a limitation on the number of allowed instances.
So far it has been RNDIS_MAX_CONFIGS, which happens to be one.
In order to eliminate this kind of arbitrary limitation we should not
preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params
instances but instead allow allocating them on demand.

This patch allocates struct rndis_params on demand in rndis_register().
Coversly, the structure is free()'d in rndis_deregister().
If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which
is the same behaviour as before, but the moment of creation is delayed
until struct rndis_params is actually allocated.

rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

H. Nikolaus Schaller e3aa205aa1 Documentation usb serial: fixed how to provide vendor and product id
While trying to test a Cinterion GSM/GPS/3G module I had reconfigured
the USB interface by mistake and therefore needed to run a different
USB driver than CDC-ACM. It turned out that I need the "usbserial" driver.

This file is an official description how to use it:
Documentation/usb/usb-serial.txt

But it is outdated. The parameters vendor= and product= have been
superseded by a /sys interface.

Here was the solution:

https://bbs.archlinux.org/viewtopic.php?id=175499

  insmod usbserial vendor=0x#### product=0x####

becomes (first #### is vendor, second is product)

  modprobe usbserial
  echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id

This patch changes the documentation file to describe the modern variant.
Please note that the old one still works (if compiled as module).

usb: patches for v4.1 merge window

As usual, a big pile of commits. This time a total
of 111 non-merge commits.

Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.

The printer gadget has been converted to configfs interface
and the atmel udc has learned suspend/resume with wakeup.

Greg Kroah-Hartman 4d4bac4499 usb: patches for v3.20 merge window
Here's the big pull request for Gadgets and PHYs. It's
 a total of 217 non-merge commits with pretty much everything
 being touched.
 
 The most important bits are a ton of new documentation for
 almost all usb gadget functions, a new isp1760 UDC driver,
 several improvements to the old net2280 UDC driver, and
 some minor tracepoint improvements to dwc3.
 
 Other than that, a big list of minor cleanups, smaller bugfixes
 and new features all over the place.

After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so quite a few
depend on CONFIG_PM (or even dropped in some cases).

Replace CONFIG_PM_RUNTIME with CONFIG_PM in the USB core code
and documentation.
