    usb: patches for v3.10 merge window
    Here is the big Gadget & PHY pull request. Many of us have
    been really busy lately getting multiple drivers to a better
    Since this pull request is so large, I will divide it in sections
    so it's easier to grasp what's included.
    - cleanups:
    	. UDC drivers no longer touch gadget->dev, that's now udc-core
    	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
    	. UDC drivers no longer initialize DMA-related fields from gadget's
    		device structure
    	. UDC drivers don't touch gadget.dev.driver directly
    	. UDC drivers don't assign gadget.dev.release directly
    	. Removal of some unused DMA_ADDR_INVALID
    	. Introduction of CONFIG_USB_PHY
    	. All phy drivers have been moved to drivers/usb/phy and renamed to
    		a common naming scheme
    	. Fix PHY layer so it never returns a NULL pointer, also fix all
    		callers to avoid using IS_ERR_OR_NULL()
    	. Sparse fixes all over the place
    	. drivers/usb/otg/ has been deleted
    	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
    - new features:
    	. UDC core now provides a generic way for tracking and reporting
    		UDC's state (not attached, resuming, suspended, addressed,
    		default, etc)
    	. twl4030-usb learned that it shouldn't be enabled during init
    	. Full DT support for DWC3 has been implemented
    	. ab8500-usb learned about pinctrl framework
    	. nop PHY learned about DeviceTree and regulators
    	. DWC3 learned about suspend/resume
    	. DWC3 can now be compiled in host-only and gadget-only (as well as
    		DRD) configurations
    	. UVC now enables streaming endpoint based on negotiated speed
    	. isp1301 now implements the PHY API properly
    	. configfs-based interface for gadget drivers which will lead to
    		the removal of all code which just combines functions together
    		to build functional gadget drivers.
    	. f_serial and f_obex were converted to new configfs interface while
    		maintaining old interface around.
    - non-critical fixes:
    	. UVC gadget driver got fixes for Endpoint usage and stream calculation
    	. ab8500-usb fixed unbalanced clock and regulator API usage
    	. twl4030-usb got a fix for when OMAP3 is booted with cable connected
    	. fusb300_udc got a fix for DMA usage
    	. UVC got fixes for two assertions of the USB Video Class Compliance
    		specification revision 1.1
    	. build warning issues caused by recent addition of __must_check to
    		regulator API
    These are all changes which deserve a mention, all other changes are related
    to these one or minor spelling fixes and other similar tasks.
