Merge tag 'usb-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB and PHY updates from Greg KH:
 "Here is the big USB pull request for 4.18-rc1.

  Lots of stuff here, the highlights are:

   - phy driver updates and new additions

   - usual set of xhci driver updates

   - normal set of musb updates

   - gadget driver updates and new controllers

   - typec work, it's getting closer to getting fully out of the staging
     portion of the tree.

   - lots of minor cleanups and bugfixes.

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

+Description:
+		In some cases, we care about time-to-active for devices
+		connected on a specific port (e.g. non-standard USB port like
+		pogo pins), where the device to be connected is known in
+		advance, and behaves well according to the specification.
+		This attribute is a bit-field that controls the behavior of
+		a specific port:
+		 - Bit 0 of this field selects the "old" enumeration scheme,
+		   as it is considerably faster (it only causes one USB reset
+		   instead of 2).
+		   The old enumeration scheme can also be selected globally
+		   using /sys/module/usbcore/parameters/old_scheme_first, but
+		   it is often not desirable as the new scheme was introduced to
+		   increase compatibility with more devices.
+		 - Bit 1 reduces TRSTRCY to the 10 ms that are required by the
+		   USB 2.0 specification, instead of the 50 ms that are normally
+		   used to help make enumeration work better on some high speed
+		   devices.
