Merge tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB patches from Greg Kroah-Hartman:
 "Here's the big USB pull request for 3.10-rc1.

  Lots of USB patches here, the majority being USB gadget changes and
  USB-serial driver cleanups, the rest being ARM build fixes / cleanups,
  and individual driver updates.  We also finally got some chipidea
  fixes, which have been delayed for a number of kernel releases, as the
  maintainer has now reappeared.

  All of these have been in linux-next for a while"

OMAP HS USB EHCI controller



This device is usually the child of the omap-usb-host

Documentation/devicetree/bindings/mfd/omap-usb-host.txt



Required properties:



- compatible: should be "ti,ehci-omap"

- reg: should contain one register range i.e. start and length

- interrupts: description of the interrupt line



Optional properties:



- phys: list of phandles to PHY nodes.

  This property is required if at least one of the ports are in

  PHY mode i.e. OMAP_EHCI_PORT_MODE_PHY



To specify the port mode, see

Documentation/devicetree/bindings/mfd/omap-usb-host.txt



Example for OMAP4:



usbhsehci: ehci@4a064c00 {

	compatible = "ti,ehci-omap", "usb-ehci";

	reg = <0x4a064c00 0x400>;
