+Driver for Broadcom Northstar USB 2.0 PHY
+
+Required properties:
+- compatible: brcm,ns-usb2-phy
+- reg: iomem address range of DMU (Device Management Unit)
+- reg-names: "dmu", the only needed & supported reg right now
+- clocks: USB PHY reference clock
+- clock-names: "phy-ref-clk", the only needed & supported clock right now
+
+To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
+requires passing phandle to the USB PHY reference clock.
+
+Example:
+ usb2-phy {
+ compatible = "brcm,ns-usb2-phy";
+ reg = <0x1800c000 0x1000>;
+ reg-names = "dmu";
+ #phy-cells = <0>;
+ clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>;
+ clock-names = "phy-ref-clk";
+ };
