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"

Contact: Mathias Nyman <mathias.nyman@linux.intel.com>
Description:
USB 2.0 devices may support hardware link power management (LPM)
L1 sleep state. The usb2_lpm_l1_timeout attribute allows
tuning the timeout for L1 inactivity timer (LPM timer), e.g.
needed inactivity time before host requests the device to go to L1 sleep.
Useful for power management tuning.
Supported values are 0 - 65535 microseconds.
What: /sys/bus/usb/devices/.../power/usb2_lpm_besl
Date: May 2013
Contact: Mathias Nyman <mathias.nyman@linux.intel.com>
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)
