Here's the big USB pull request for 3.14-rc1
Lots of little things all over the place, and the usual USB gadget
updates, and XHCI fixes (some for an issue reported by a lot of people.)
USB PHY updates as well as chipidea updates and fixes.
All of these have been in the linux-next tree with no reported issues.

Kirkwood and Dove can turn the SATA phy on and off. Add a PHY driver
to control this.

Used the generic PHY framework API to create the PHY. For powering on
and powering off the PHY, power_on and power_off ops are used. Once the
MUSB OMAP glue is adapted to the new framework, the suspend and resume
ops of usb phy library will be removed. Also twl4030-usb driver is moved
to drivers/phy/.
However using the old usb phy library cannot be completely removed
because otg is intertwined with phy and moving to the new
framework completely will break otg. Once we have a separate otg state machine,
we can get rid of the usb phy library.

Used the generic PHY framework API to create the PHY. Now the power off and
power on are done in omap_usb_power_off and omap_usb_power_on respectively.
The omap-usb2 driver is also moved to driver/phy.

The PHY framework provides a set of APIs for the PHY drivers to
create/destroy a PHY and APIs for the PHY users to obtain a reference to the
PHY with or without using phandle. For dt-boot, the PHY drivers should
also register *PHY provider* with the framework.
PHY drivers should create the PHY by passing id and ops like init, exit,
power_on and power_off. This framework is also pm runtime enabled.
The documentation for the generic PHY framework is added in
Documentation/phy.txt and the documentation for dt binding can be found at
Documentation/devicetree/bindings/phy/phy-bindings.txt
