ROCKCHIP USB 3.0 PHY WITH INNO IP BLOCK

Required properties (phy (parent) node):
 - compatible:	should be one of the listed compatibles:
   * "rockchip,rk3328-u3phy"
   * "rockchip,rk322xh-u3phy"
 - reg : the base address of USB 3.0 PHY.
 - rockchip,u3phygrf : phandle to the syscon managing the
		       "USB 3.0 PHY general register files".
 - interrupts : specify an interrupt for each entry in interrupt-names.
 - interrupt-names : a list which shall be the following entries:
   * "linestate" : for the host/otg linestate interrupt
 - clocks : phandle + clock specifier for the phy clocks.
 - clock-names :
   * "u3phy-otg" for USB 3.0 PHY utmi
   * "u3phy-pipe" for USB 3.0 PHY pipe
 - resets : a list of phandle + reset specifier pairs
 - reset-names :
   * "u3phy-u2-por" for the USB 2.0 logic of USB 3.0 PHY
   * "u3phy-u3-por" for the USB 3.0 logic of USB 3.0 PHY
   * "u3phy-pipe-mac" for the USB 3.0 PHY pipe MAC
   * "u3phy-utmi-mac" for the USB 3.0 PHY utmi MAC
   * "u3phy-utmi-apb" for the USB 3.0 PHY utmi apb
   * "u3phy-pipe-apb" for the USB 3.0 PHY pipe apb

Optional properties:
 - vbus-supply: regulator phandle for vbus power source.

Required nodes : a sub-node is required for USB 3.0 or USB 2.0 the phy provides.
		 The sub-node name is used to identify phy type, and shall be
		 the following entries:
	* "u3phy_utmi" : USB 2.0 utmi phy.
	* "u3phy_pipe" : USB 3.0 pipe phy.

Required properties (port (child) node):
 - reg : address and length of the register set for the port.
 - #phy-cells : must be 0. See ./phy-bindings.txt for details.

Optional properties for utmi node:
 - rockchip,odt-val-tuning : specify 45ohm ODT tuning value.

Optional properties for pipe node:
 - rockchip,refclk-25m-quirk : phy reference clock changed to 25m quirk.
