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.

Some platforms (e.g. TI's DRA7 USB2 instance) have more trouble
with the metastability workaround as it supports only
a High-Speed PHY and the PHY can enter into an Erratic state [1]
when the controller is set in SuperSpeed mode as part of
the metastability workaround.

This causes upto 2 seconds delay in enumeration on DRA7's USB2
instance in gadget mode.

If these platforms can be better off without the workaround,
provide a device tree property to suggest that so the workaround
is avoided.

Pull media fixes from Mauro Carvalho Chehab:

 "A series of fixes for the media subsytem:

   - The largest amount of fixes in this series is with regards to
     comments that aren't kernel-doc, but start with "/**".

     A new check added for 4.15 makes it to produce a *huge* amount of
     new warnings (I'm compiling here with W=1). Most of the patches in
     this series fix those.

     No code changes - just comment changes at the source files

   - rc: some fixed in order to better handle RC repetition codes

   - v4l-async: use the v4l2_dev from the root notifier when matching
     sub-devices

   - v4l2-fwnode: Check subdev count after checking port

   - ov 13858 and et8ek8: compilation fix with randconfigs

   - usbtv: a trivial new USB ID addition

   - dibusb-common: don't do DMA on stack on firmware load

   - imx274: Fix error handling, add MAINTAINERS entry

   - sir_ir: detect presence of port"

Pull drm fixes from Dave Airlie:
 "This pull is a bit larger than I'd like but a large bunch of it is
  license fixes, AMD wanted to fix the licenses for a bunch of files
  that were missing them,

 Otherwise a bunch of TTM regression fix since the hugepage support,
 some i915 and gvt fixes, a core connector free in a safe context fix,
 and one bridge fix"
