+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 pipe 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 at least one of following:
+ "inno": for inno phy
+ "combo": for combo phy
+
+Optional properties:
+ - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM
+ - usb3-lpm-capable: determines if platform is USB3 LPM capable
+ - imod-interval-ns: default interrupt moderation interval is 40000ns
+
+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";
+};
