Pull USB updates from Greg KH:
 "Here's the big USB patchset for 3.18-rc1.  Also in here is the PHY
  tree, as it seems to fit well with the USB tree for various reasons...

  Anyway, lots of little changes in here, all over the place, full
  details in the changelog

  All have been in the linux-next tree for a while with no issues"

+ST USB OHCI controller
+
+Required properties:
+
+ - compatible		: must be "st,st-ohci-300x"
+ - reg			: physical base addresses of the controller and length of memory mapped
+			  region
+ - interrupts		: one OHCI controller interrupt should be described here
+ - clocks		: phandle list of usb clocks
+ - clock-names		: should be "ic" for interconnect clock and "clk48"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+ - phys			: phandle for the PHY device
+ - phy-names		: should be "usb"
+
+ - resets		: phandle to the powerdown and reset controller for the USB IP
+ - reset-names		: should be "power" and "softreset".
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
