Along with the normally expected XHCI, MUSB, and Gadget driver
patches, there are some PHY driver fixes, license cleanups, sysfs
attribute cleanups, usbip changes, and a raft of other smaller fixes
and additions.

Full details are in the shortlog.

All of these have been in the linux-next tree for a long time with no
reported issues"

usb: changes for v4.16 merge window

Not many changes here, the most important being an improvement for TI's
AM57xx and DRA7xx devices which allows them to disable a metastability
workaround in situations where we know what's going on.

Other than that, we have a set of changes on Renesas UDC to make the
code a little easier to read and maintain while also better supporting
extcon framework.

The u_serial adaptation layer learned to use kfifo instead of cooking
its own FIFO implementation.

DWC3 learned to decode a few more USB requests on the trace output.

usb: dwc2: host: Don't retry NAKed transactions right away

On rk3288-veyron devices on Chrome OS it was found that plugging in an
Arduino-based USB device could cause the system to lockup, especially
if the CPU Frequency was at one of the slower operating points (like
100 MHz / 200 MHz).

Upon tracing, I found that the following was happening:
* The USB device (full speed) was connected to a high speed hub and
then to the rk3288. Thus, we were dealing with split transactions,
which is all handled in software on dwc2.
* Userspace was initiating a BULK IN transfer
* When we sent the SSPLIT (to start the split transaction), we got an
ACK. Good. Then we issued the CSPLIT.
* When we sent the CSPLIT, we got back a NAK. We immediately (from
the interrupt handler) started to retry and sent another SSPLIT.
* The device kept NAKing our CSPLIT, so we kept ping-ponging between
sending a SSPLIT and a CSPLIT, each time sending from the interrupt
handler.
* The handling of the interrupts was (because of the low CPU speed and
the inefficiency of the dwc2 interrupt handler) was actually taking
_longer_ than it took the other side to send the ACK/NAK. Thus we
were _always_ in the USB interrupt routine.
* The fact that USB interrupts were always going off was preventing
other things from happening in the system. This included preventing
the system from being able to transition to a higher CPU frequency.

As I understand it, there is no requirement to retry super quickly
after a NAK, we just have to retry sometime in the future. Thus one
solution to the above is to just add a delay between getting a NAK and
retrying the transmission. If this delay is sufficiently long to get
out of the interrupt routine then the rest of the system will be able
to make forward progress. Even a 25 us delay would probably be
enough, but we'll be extra conservative and try to delay 1 ms (the
exact amount depends on HZ and the accuracy of the jiffy and how close
the current jiffy is to ticking, but could be as much as 20 ms or as
little as 1 ms).

Presumably adding a delay like this could impact the USB throughput,
so we only add the delay with repeated NAKs.

NOTE: Upon further testing of a pl2303 serial adapter, I found that
this fix may help with problems there. Specifically I found that the
pl2303 serial adapters tend to respond with a NAK when they have
nothing to say and thus we end with this same sequence.

USB: add SPDX identifiers to all remaining files in drivers/usb/

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.
