   2
   3 Required properties (phy (parent) node):
   4  - compatible: should contain:
   5         * "rockchip,rk3366-usb2phy"
   6  - #clock-cells: should be 0.
   7  - clock-names: specify the 480m output clk name.
   8
   9 Optional properties:
  10  - vbus_host-gpio: pull gpio high/low to control the host vbus power.
  11
  12 Required nodes: a sub-node is required for each port the phy provides.
  13                 The sub-node name is used to identify host or otg port.
  14
  15 Required properties (port (child) node):
  16  - #phy-cells: must be 0. See ./phy-bindings.txt for details.
  17  - interrupts: irq number for host/otg port.
  18  - interrupt-names: interrupt name, in line with irq number.
