+* HISILICON USB HUB
+
+Required properties:
+- compatible: One of the specific types :"hisilicon,hi3660-dwc3",
+ "hisilicon,gpio_hubv1","hisilicon,gpio_hubv2"
+
+Optional properties of devices using ISP1301:
+- transceiver: phandle of isp1301 - this helps the ISP1301 driver to find the
+ ISP1301 instance associated with the respective USB driver
+
+Example:
+
+ hisi_usb@ff200000 {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ compatible = "hisilicon,hi3660-dwc3";
+ reg = <0x0 0xff200000 0x0 0x1000
+ 0x0 0xff100000 0x0 0x100000>;
+ ranges;
+ bc_again_flag = <0>;
+
+ clocks = <&crg_ctrl HI3660_CLK_ABB_USB>,
+ <&crg_ctrl HI3660_ACLK_GATE_USB3OTG>;
+ clock-names = "clk_usb3phy_ref", "aclk_usb3otg";
+ eye_diagram_param = <0x1c466e3>;
+ eye_diagram_host_param = <0x1c466e3>;
+ usb3_phy_cr_param = <0xb80>;
+ usb3_phy_host_cr_param = <0x980>;
+ usb3_phy_tx_vboost_lvl = <0x5>;
+
+ dwc3@ff100000 {
+ compatible = "snps,dwc3";
+ reg = <0x0 0xff100000 0x0 0x100000>;
+ interrupts = <0 159 4>, <0 161 4>;
+ dr_mode = "otg";
