Changes in v3:
- Added 'clocks' and 'clock-names' optional properties.
- Specified 'otg-port' and 'host-port' as the sub-node name.
Changes in v2:

+ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
+
+Required properties (phy (parent) node):
+ - compatible : should be one of the listed compatibles:
+ * "rockchip,rk3366-usb2phy"
+ * "rockchip,rk3399-usb2phy"
+ - #clock-cells : should be 0.
+ - clock-output-names : specify the 480m output clock name.
+
+Optional properties:
+ - clocks : phandle + phy specifier pair, for the input clock of phy.
+ - clock-names : input clock name of phy, must be "phyclk".
+ - vbus_host-supply : phandle to a regulator that supplies host vbus.
+ - vbus_otg-supply : phandle to a regulator that supplies otg vbus.
+
+Required nodes : a sub-node is required for each port the phy provides.
+ The sub-node name is used to identify host or otg port,
+ and shall be the following entries:
+ * "otg-port" : the name of otg port.
+ * "host-port" : the name of host port.
+
+Required properties (port (child) node):
+ - #phy-cells : must be 0. See ./phy-bindings.txt for details.
+ - interrupts : specify an interrupt for each entry in interrupt-names.
+ - interrupt-names : a list which shall be the following entries:
+ * "otg_id" : for the otg id interrupt.
+ * "otg_bvalid" : for the otg vbus interrupt.
+ * "linestate" : for the host/otg linestate interrupt.
+
+Example:
+
+grf: syscon@ff770000 {
+ compatible = "rockchip,rk3366-grf", "syscon", "simple-mfd";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+...
+
+ u2phy: usb2-phy {
+ compatible = "rockchip,rk3366-usb2phy";
+ #clock-cells = <0>;
+ clock-output-names = "sclk_otgphy0_480m";
+
+ u2phy_otg: otg-port {
+ #phy-cells = <0>;
+ interrupts = <GIC_SPI 93 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 94 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 95 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "otg_id", "otg_bvalid", "linestate";
+ status = "okay";
+ };
+
+ u2phy_host: host-port {
+ #phy-cells = <0>;
+ interrupts = <GIC_SPI 96 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "linestate";
+ status = "okay";
+ };
+ };
+};
