1Driver for Broadcom Northstar USB 2.0 PHY
2
3Required properties:
4- compatible: brcm,ns-usb2-phy
5- reg: iomem address range of DMU (Device Management Unit)
6- reg-names: "dmu", the only needed & supported reg right now
7- clocks: USB PHY reference clock
8- clock-names: "phy-ref-clk", the only needed & supported clock right now

10To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
11requires passing phandle to the USB PHY reference clock.

13Example:
14	usb2-phy {
15		compatible = "brcm,ns-usb2-phy";
16		reg = <0x1800c000 0x1000>;
17		reg-names = "dmu";
18		#phy-cells = <0>;
19		clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>;
20		clock-names = "phy-ref-clk";
21	};
