Merge tag 'usb-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big set of USB and PHY driver patches for 4.17-rc1.

  Lots of USB typeC work happened this round, with code moving from the
  staging directory into the "real" part of the kernel, as well as new
  infrastructure being added to be able to handle the different types of
  "roles" that typeC requires.

  There is also the normal huge set of USB gadget controller and driver
  updates, along with XHCI changes, and a raft of other tiny fixes all
  over the USB tree. And the PHY driver updates are merged in here as
  well as they interacted with the USB drivers in some places.

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

 	usbcore.nousb	[USB] Disable the USB subsystem
 
+	usbcore.quirks=
+			[USB] A list of quirk entries to augment the built-in
+			usb core quirk list. List entries are separated by
+			commas. Each entry has the form
+			VendorID:ProductID:Flags. The IDs are 4-digit hex
+			numbers and Flags is a set of letters. Each letter
+			will change the built-in quirk; setting it if it is
+			clear and clearing it if it is set. The letters have
+			the following meanings:
+				a = USB_QUIRK_STRING_FETCH_255 (string
+					descriptors must not be fetched using
+					a 255-byte read);
+				b = USB_QUIRK_RESET_RESUME (device can't resume
+					correctly so reset it instead);
+				c = USB_QUIRK_NO_SET_INTF (device can't handle
+					Set-Interface requests);
+				d = USB_QUIRK_CONFIG_INTF_STRINGS (device can't
+					handle its Configuration or Interface
+					strings);
+				e = USB_QUIRK_RESET (device can't be reset
+					(e.g morph devices), don't use reset);
+				f = USB_QUIRK_HONOR_BNUMINTERFACES (device has
+					more interface descriptions than the
+					bNumInterfaces count, and can't handle
+					talking to these interfaces);
+				g = USB_QUIRK_DELAY_INIT (device needs a pause
+					during initialization, after we read
+					the device descriptor);
+				h = USB_QUIRK_LINEAR_UFRAME_INTR_BINTERVAL (For
+					high speed and super speed interrupt
+					endpoints, the USB 2.0 and USB 3.0 spec
+					require the interval in microframes (1
+					microframe = 125 microseconds) to be
+					calculated as interval = 2 ^
+					(bInterval-1).
+					Devices with this quirk report their
+					bInterval as the result of this
+					calculation instead of the exponent
+					variable used in the calculation);
+				i = USB_QUIRK_DEVICE_QUALIFIER (device can't
+					handle device_qualifier descriptor
+					requests);
+				j = USB_QUIRK_IGNORE_REMOTE_WAKEUP (device
+					generates spurious wakeup, ignore
+					remote wakeup capability);
+				k = USB_QUIRK_NO_LPM (device can't handle Link
+					Power Management);
+				l = USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL
+					(Device reports its bInterval as linear
+					frames instead of the USB 2.0
+					calculation);
+				m = USB_QUIRK_DISCONNECT_SUSPEND (Device needs
+					to be disconnected before suspend to
+					prevent spurious wakeup);
+				n = USB_QUIRK_DELAY_CTRL_MSG (Device needs a
+					pause after every control message);
+			Example: quirks=0781:5580:bk,0a5c:5834:gij

 	usbhid.mousepoll=
