Merge tag 'usb-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB driver updates from Greg KH:
 "Here's the big USB (and PHY) driver patchset for 4.1-rc1.

  Everything here has been in linux-next, and the full details are below
  in the shortlog.  Nothing major, just the normal round of new
  drivers,api updates, and other changes, mostly in the USB gadget area,
  as usual"

+ * USB Resume Timer: Every Host controller driver should drive the resume

+ * That way we will have a 'stable' behavior among all HCDs supported by Linux.
+ *
+ * Note that the USB Specification states we should drive resume for *at least*
+ * 20 ms, but it doesn't give an upper bound. This creates two possible
+ * situations which we want to avoid:
+ *
+ * (a) sometimes an msleep(20) might expire slightly before 20 ms, which causes
+ * us to fail USB Electrical Tests, thus failing Certification
+ *
+ * (b) Some (many) devices actually need more than 20 ms of resume signalling,
+ * and while we can argue that's against the USB Specification, we don't have
+ * control over which devices a certification laboratory will be using for
+ * certification. If CertLab uses a device which was tested against Windows and
+ * that happens to have relaxed resume signalling rules, we might fall into
+ * situations where we fail interoperability and electrical tests.
+ *
+ * In order to avoid both conditions, we're using a 40 ms resume timeout, which
+ * should cope with both LPJ calibration errors and devices not following every
+ * detail of the USB Specification.
