+HiSilicon DWC3 USB SoC controller
+
+This file documents the parameters for the dwc3-hisi driver.
+
+Required properties:
+- compatible: should be "hisilicon,hi3660-dwc3"
+- clocks: A list of phandle + clock-specifier pairs for the
+ clocks listed in clock-names
+- clock-names: Specify clock names
+- resets: list of phandle and reset specifier pairs.
+
+Sub-nodes:
+The dwc3 core should be added as subnode to HiSilicon DWC3 as shown in the
+example below. The DT binding details of dwc3 can be found in:
+Documentation/devicetree/bindings/usb/dwc3.txt
+
+Example:
+ usb3: hisi_dwc3 {
+ compatible = "hisilicon,hi3660-dwc3";
+ #address-cells = <2>;
+ #size-cells = <2>;
+ ranges;
+
+ clocks = <&crg_ctrl HI3660_CLK_ABB_USB>,
+ <&crg_ctrl HI3660_ACLK_GATE_USB3OTG>;
+ clock-names = "clk_usb3phy_ref", "aclk_usb3otg";
+ assigned-clocks = <&crg_ctrl HI3660_ACLK_GATE_USB3OTG>;
+ assigned-clock-rates = <229000000>;
+ resets = <&crg_rst 0x90 8>,
+ <&crg_rst 0x90 7>,
+ <&crg_rst 0x90 6>,
+ <&crg_rst 0x90 5>;
+
+ dwc3: dwc3@ff100000 {
+ compatible = "snps,dwc3";
+ reg = <0x0 0xff100000 0x0 0x100000>;
