+Hisilicon hi6220 SoC USB controller
+-----------------------------
+
+usb controller is inherited from dwc2, refer dwc2.txt
+-----
+
+Required properties:
+- compatible: "hisilicon,hi6220-usb"
+Refer to dwc2.txt for dwc2 usb properties
+
+
+PHY:
+-----
+
+Required properties:
+- compatible: "hisilicon,hi6220-usb-phy"
+- vcc-supply: phandle to the regulator that provides power to the PHY.
+- clocks: phandle and clock specifier of the PHY clock.
+- hisilicon,peripheral-syscon: phandle of syscon used to control peripheral.
+- hisilicon,gpio-vbus: gpio of detecting vbus.
+- hisilicon,gpio-id: gpio of detecting id.
+
+Example:
+
+ peripheral_ctrl: syscon@f7030000 {
+ compatible = "syscon";
+ reg = <0x0 0xf7030000 0x0 0x1000>;
+ };
+
+ usb2_phy: usbphy {
+ compatible = "hisilicon,hi6220-usb-phy";
+ vcc-supply = <&fixed_5v_hub>;
+ hisilicon,gpio-vbus = <&gpio2 6 0>;
+ hisilicon,gpio-id = <&gpio2 5 0>;
+ hisilicon,peripheral-syscon = <&peripheral_ctrl>;
+ clocks = <&clock_sys HI6220_USBOTG_HCLK>;
+ };
+
+ usb: usb@f72c0000 {
+ compatible = "hisilicon,hi6220-usb";
+ reg = <0x0 0xf72c0000 0x0 0x40000>;
+ phys = <&usb2_phy>;
+ dr_mode = "otg";
+ g-use-dma;
+ g-rx-fifo-size = <512>;
+ g-np-tx-fifo-size = <128>;
+ g-tx-fifo-size = <128>;
+ interrupts = <0 77 0x4>;
+ };
