+HiSilicon STB xHCI
+
+The device node for HiSilicon STB xHCI host controller
+
+Required properties:
+ - compatible : should be "hisilicon,hi3798cv200-xhci"
+ - reg : specifies physical base address and size of the registers
+ - interrupts : interrupt used by the controller
+ - clocks : a list of phandle + clock-specifier pairs, one for each
+	entry in clock-names
+ - clock-names : must contain
+	"bus": for bus clock
+	"utmi": for utmi clock
+	"pipe": for pipeE clock
+	"suspend": for suspend clock
+ - resets: a list of phandle and reset specifier pairs as listed in
+	reset-names property.
+ - reset-names: must contain
+	"soft": for soft reset
+ - phys : a list of phandle + phy specifier pairs
+ - phy-names: must contain one of following at least:
+	"inno": for inno phy
+	"combo": for combo phy
+
+Example:
+
+xhci0: xchi@f98a0000 {
+	compatible = "hisilicon,hi3798cv200-xhci";
+	reg = <0xf98a0000 0x10000>;
+	interrupts = <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
+	clocks = <&crg HISTB_USB3_BUS_CLK>,
+		 <&crg HISTB_USB3_UTMI_CLK>,
+		 <&crg HISTB_USB3_PIPE_CLK>,
+		 <&crg HISTB_USB3_SUSPEND_CLK>;
+	clock-names = "bus", "utmi", "pipe", "suspend";
+	resets = <&crg 0xb0 12>;
+	reset-names = "soft";
+	phys = <&usb2_phy1_port1 0>, <&combphy0 PHY_TYPE_USB3>;
+	phy-names = "inno", "combo";
+};
