   1 Driver for Broadcom Northstar USB 2.0 PHY
   2
   3 Required 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
   9
  10 To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
  11 requires passing phandle to the USB PHY reference clock.

  13 Example:
  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         };
