* 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@d4208000 {
		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";
	};
