+* Marvell PXA1928 USB and HSIC PHYs
+
+Required properties:
+- compatible: "marvell,pxa1928-usb-phy" or "marvell,pxa1928-hsic-phy"
+- reg: base address and length of the registers
+- clocks - A single clock. From common clock binding.
+- #phys-cells: should be 0. From commmon phy binding.
+- resets: reference to the reset controller
+
+Example:
+
+       usbphy: phy@7000 {
+               compatible = "marvell,pxa1928-usb-phy";
+               reg = <0x7000 0xe0>;
+               clocks = <&apmu_clocks PXA1928_CLK_USB>;
+               #phy-cells = <0>;
+       };
