Linus Torvalds e7cf773d43 USB patches for 3.19-rc1
Here's the big set of USB and PHY patches for 3.19-rc1.
 
 The normal churn in the USB gadget area is in here, as well as xhci and
 other individual USB driver updates.  The PHY tree is also in here, as
 there were dependancies on the USB tree.
 
 All of these have been in linux-next.

Rafael J. Wysocki ceb6c9c862 USB / PM: Drop CONFIG_PM_RUNTIME from the USB core
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.

USB hub has started to use a workqueue instead of kthread. Let's update

This patch mostly just replaces "khubd" with "hub_wq". There are only few
exceptions where the whole sentence was updated. These more complicated
changes can be found in the following files:

Thomas Pugliese 005799d560 uwb: doc: bring uwb documentation up to date
The existing UWB documentation states that UWB devices show up in
/sys/class/uwb and /sys/bus/uwb/devices.  Up until the most recent
changes to add uwb devices to their own bus, neither of these statements
were actually true.  Now, UWB devices do show up in /sys/bus/uwb/devices
so the documentation has been updated to reflect that and removed
references to /sys/class/uwb.

The existing documentation also states that local UWB radio controller
(RC) devices also show up as UWB devices along with their wireless peer
UWB devices under /sys/class/uwb.  This is not true so that statement
has been removed.

Ming Lei 85721d4526 USB: URB documentation: claim complete() will be run with IRQs enabled
There is no good reason to run complete() in hard interrupt
disabled context.

After switch to run complete() in tasklet, we will enable local IRQs
when calling complete() since we can do it at that time.

Even though we still disable IRQs now when calling complete()
in tasklet, the URB documentation is updated to claim complete()
will be run in tasklet context and local IRQs will be enabled, so
that USB drivers can know the change and avoid one deadlock caused
by: assume IRQs disabled in complete() and call spin_lock() to
hold lock which might be acquired in interrupt context.

Current spin_lock() usages in drivers' complete() will be cleaned
up at the same time, and once the cleanup is finished, local IRQs
will be enabled when calling complete() in tasklet.

Also fix description about type of usb_complete_t, and remove the
advice of running completion handler in tasklet for decreasing
system latency.

 While removing g_file_storage, we also had to fix a bunch
 of defconfigs which were still pointing to the old gadget.
 
 There's a big series getting us closer to being able to
 introduce our configfs interface. The series converts
 functions into loadable modules which will, eventually,
 be registered to the configfs interface.
 
 Other than that there's the usual typo fixes and miscelaneous
 cleanups all over the place.

Sebastian Andrzej Siewior 2e8dc2f2c1 usb/usbmon: correct the data interpretation of usbmon's output
The doc says that the data
| 55534243 5e000000 00000000 00000600 00000000 00000000 00000000 000000
is the SCSI command 0x5e. According to the usbmon source, it dumps one
byte after the other. The first 4 bytes are US_BULK_CB_SIGN which is
correct. After that we see the TAG which is 0x5e. The cdb is 0x00 in
this example.
In order to correct this, I change the example to a READ_10 command
which is 0x28 so it is not just a zero somewhere in the stream.

Felipe Balbi 72246da40f usb: Introduce DesignWare USB3 DRD Driver
The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.

Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.

The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.

More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.

While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.

This patch (as1482) adds a macro for testing whether or not a
