Merge tag 'for-usb-next-2012-11-28' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next

From Sarah:
  "xhci: Intel Lynx Point LP support.

  Hi Greg,

  Here's a patch to add the new Intel Lynx Point LP chipset to the list of Intel
  xHCI hosts that need the EHCI to xHCI port switchover.

  Please queue for 3.8.

  Sarah Sharp"

Like Lynx Point, Lynx Point LP is also switchable.  See
1c12443a for more details.

This patch should be backported to stable kernels as old as 3.0,
that contain commit 69e848c2
"Intel xhci: Support EHCI/xHCI port switching."

The Newport AGILIS model AG-UC8 compact piezo motor controller
(http://search.newport.com/?q=*&x2=sku&q2=AG-UC8)
is yet another device using an FTDI USB-to-serial chip. It works
fine with the ftdi_sio driver when adding

  options ftdi-sio product=0x3000 vendor=0x104d

to modprobe.d. udevadm reports "Newport" as the manufacturer,
and "Agilis" as the product name.

BeagleBone A5+ devices ended up getting shipped with the
'BeagleBone/XDS100V2' product string, and not XDS100 like it
was agreed, so adjust the quirk to match.

For details, see the thread on the beagle list:

The Huawei E173 will normally appear as 12d1:1436 in Linux.  But
the modem has another mode with different device ID and a slightly
different set of descriptors. This is the mode used by Windows like
this:

  3Modem:      USB\VID_12D1&PID_140C&MI_00\6&3A1D2012&0&0000
  Networkcard: USB\VID_12D1&PID_140C&MI_01\6&3A1D2012&0&0001
  Appli.Inter: USB\VID_12D1&PID_140C&MI_02\6&3A1D2012&0&0002
  PC UI Inter: USB\VID_12D1&PID_140C&MI_03\6&3A1D2012&0&0003

All interfaces have the same ff/ff/ff class codes in this mode.
Blacklisting the network interface to allow it to be picked up by
the network driver.

This patch (as1636) is a partial workaround for a hardware bug
affecting OHCI controllers by NVIDIA at least, maybe others too.  When
the controller retires a Transfer Descriptor, it is supposed to add
the TD onto the Done Queue.  But sometimes this doesn't happen, with
the result that ohci-hcd never realizes the corresponding transfer has
finished.  Symptoms can vary; a typical result is that USB audio stops
working after a while.

The patch works around the problem by recognizing that TDs are always
processed in order.  Therefore, if a later TD is found on the Done
Queue than all the earlier TDs for the same endpoint must be finished
as well.

Unfortunately this won't solve the problem in cases where the missing
TD is the last one in the endpoint's queue.  A complete fix would
require a signficant amount of change to the driver.

Switch to the more efficient generic read implementation.

Note that the generic implementation is not required to hold the tty
port mutex during resume due to the read-urb free mask and write start
flag.

Note also that the generic resume implementation will call generic
write start if there is a bulk-out end-point, but that nothing will be
submitted as the write fifo is not used and is empty.
