+* USB2 ChipIdea USB controller for ci13xxx
+
+Required properties:
+- compatible: should be "chipidea,usb2"
+- reg: base address and length of the registers
+- interrupts: interrupt for the USB controller
+
+Optional properties:
+- clocks: reference to the USB clock
+- phys: reference to the USB PHY
+- phy-names: should be "usb-phy"
+- vbus-supply: reference to the VBUS regulator
+
+Example:
+
+       usb@f7ed0000 {
+               compatible = "chipidea,usb2";
+               reg = <0xf7ed0000 0x10000>;
+               interrupts = <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;
+               clocks = <&chip CLKID_USB0>;
+               phys = <&usb_phy0>;
+               phy-names = "usb-phy";
+               vbus-supply = <&reg_usb0_vbus>;
