Merge tag 'usb-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here's the big USB 3.11-rc1 merge request.

  Lots of gadget and finally, chipidea driver updates (they were much
  needed), along with a new host controller driver, lots of little
  serial driver fixes, the removal of the 255 usb-serial device
  limitation, and a variety of other minor things.

  All of these have been in the linux-next releases for a while"

+Description:
+		USB 2.0 devices may support hardware link power management (LPM)

+		tuning the timeout for L1 inactivity timer (LPM timer), e.g.

+Description:
+		USB 2.0 devices that support hardware link power management (LPM)
+		L1 sleep state now use a best effort service latency value (BESL) to
+		indicate the best effort to resumption of service to the device after the
+		initiation of the resume event.
+		If the device does not have a preferred besl value then the host can select
+		one instead. This usb2_lpm_besl attribute allows to tune the host selected besl
+		value in order to tune power saving and service latency.
+
+		Supported values are 0 - 15.
+		More information on how besl values map to microseconds can be found in
+		USB 2.0 ECN Errata for Link Power Management, section 4.10)
