Pull USB fixes from Greg KH:
 "Here are a number of USB driver fixes for 5.7-rc3.

  Nothing huge, just the usual collection of:

   - xhci fixes

   - gadget driver fixes

   - syzkaller fuzzing fixes

   - new device ids and DT bindings

   - new quirks added for broken devices

  A few of the gadget driver fixes show up twice here as they were
  applied to my branch, and also by Felipe to his branch which I then
  pulled in as we got out of sync a bit.

  All of these have been in linux-next with no reported issues"

Pull more Devicetree fixes from Rob Herring:
 "A couple of schema and kbuild fixes"

* tag 'devicetree-fixes-for-5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
  dt-bindings: phy: qcom-qusb2: Fix defaults
  dt-bindings: Fix erroneous 'additionalProperties'
  dt-bindings: Fix command line length limit calling dt-mk-schema
  dt-bindings: Re-enable core schemas for dtbs_check

The defaults listed in the bindings don't match what the code is
actually doing.  Presumably existing users care more about keeping
existing behavior the same, so change the bindings to match the code
in Linux.

The "qcom,preemphasis-level" default has been wrong for quite a long
time (May 2018).  The other two were recently added.

As some evidence that these values are wrong, this is from the Linux
driver:
- qcom,preemphasis-level: sets "PORT_TUNE1", lower 2 bits.  Driver
  programs PORT_TUNE1 to 0x30 by default and (0x30 & 0x3) = 0.
- qcom,bias-ctrl-value: sets "PLL_BIAS_CONTROL_2", lower 6 bits.
  Driver programs PLL_BIAS_CONTROL_2 to 0x20 by default and (0x20 &
  0x3f) = 0x20 = 32.
- qcom,hsdisc-trim-value: sets "PORT_TUNE2", lower 2 bits.  Driver
  programs PORT_TUNE2 to 0x29 by default and (0x29 & 0x3) = 1.

There's several cases of json-schema 'additionalProperties' at the wrong
indentation level which has the effect of making them DT properties. This
is harmless, but let's fix them so a meta-schema check for this can be
added.

In all the cases, either the 'additionalProperties' was extra or doesn't
work because there's a $ref to more properties. In the latter case, we
can use 'unevaluatedProperties' instead.

As the number of schemas has increased, we're starting to hit the error
"execvp: /bin/sh: Argument list too long". This is due to passing all the
schema files on the command line to dt-mk-schema. It currently is only
with out of tree builds and is intermittent depending on the file path
lengths.

Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made
hitting this proplem more likely since the example validation now always
gets the full list of schemas.

Fix this by passing the schema file list in a pipe and using xargs. We end
up doing the find twice, but the time is insignificant compared to the
dt-mk-schema time.
