From: Rafał Miłecki <rafal@milecki.pl>

Minor example fixes:
1. Include bcm-nsp.h
2. Add address to the node name

-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";
- };
