Merge tag 'for-usb-next-2012-03-13' of git://git./linux/kernel/git/sarah/xhci into usb-next

Hi Greg,

Here's my final pull request for 3.4.  All the patches have been under
review for some time (months in some cases).  The ring expansion patches
in particular have been tested by both me and Paul Zimmerman from
Synopsis.

They add support for:
 - Dynamic ring expansion
 - New USB 2.1 link PM errata (BESL)
 - xHCI host controller support for the Synopsis DesignWare 3 IP

The dynamic ring expansion patches finally make test 10 of the host-side
test pass, instead of failing due to no room on the endpoint ring for
the larger transfers.  I would have hoped that the ring expansion
patchset would make the Point Grey USB 3.0 camera work, but sadly it
fails to respond to a control transfer on my test system.  This doesn't
seem to be a driver bug, but it could be a device or host bug.

Felipe has tested the patches to add a platform device to the xHCI
driver on the Synopsis DesignWare 3 IP in the TI OMAP5 board.

Please pull.

Thanks,
Sarah Sharp
