-* Marvell PXA/MMP EHCI controller.
-
-Required properties:
-
-- compatible: must be "marvell,pxau2o-ehci"
-- reg: physical base addresses of the controller and length of memory mapped region
-- interrupts: one EHCI controller interrupt should be described here
-- clocks: phandle list of usb clocks
-- clock-names: should be "USBCLK"
-- phys: phandle for the PHY device
-- phy-names: should be "usb"
-
-Example:
-
-	ehci0: usb-ehci@...08000 {
-		compatible = "marvell,pxau2o-ehci";
-		reg = <0xd4208000 0x200>;
-		interrupts = <44>;
-		clocks = <&soc_clocks MMP2_CLK_USB>;
-		clock-names = "USBCLK";
-		phys = <&usb_otg_phy>;
-		phy-names = "usb";
-	};
