  16. - "amcc,dwc-otg": The DWC2 USB controller instance in AMCC Canyonlands 460EX SoCs;
  17. - snps,dwc2: A generic DWC2 USB controller with default parameters.
  18. - "st,stm32f4x9-fsotg": The DWC2 USB FS/HS controller instance in STM32F4x9 SoCs
  19. configured in FS mode;
  20. - "st,stm32f4x9-hsotg": The DWC2 USB HS controller instance in STM32F4x9 SoCs
  21. configured in HS mode;
  22. - "st,stm32f7-hsotg": The DWC2 USB HS controller instance in STM32F7 SoCs
  23. configured in HS mode;
  24. - reg : Should contain 1 register range (address and length)
  25. - interrupts : Should contain 1 interrupt
  26. - clocks: clock provider specifier
  27. - clock-names: shall be "otg"
  28. Refer to clk/clock-bindings.txt for generic clock consumer properties
  29. Optional properties:
  30. - phys: phy provider specifier
  31. - phy-names: shall be "usb2-phy"
  32. Refer to phy/phy-bindings.txt for generic phy consumer properties
  33. - dr_mode: shall be one of "host", "peripheral" and "otg"
  34. Refer to usb/generic.txt
  35. - g-rx-fifo-size: size of rx fifo size in gadget mode.
  36. - g-np-tx-fifo-size: size of non-periodic tx fifo size in gadget mode.
  37. - g-tx-fifo-size: size of periodic tx fifo per endpoint (except ep0) in gadget mode.
  38. - usb33d-supply: external VBUS and ID sensing comparators supply, in order to
  39. perform OTG operation, used on STM32MP1 SoCs.
  40. - u-boot,force-b-session-valid: force B-peripheral session instead of relying on
  41. VBUS sensing (only valid when dr_mode = "peripheral" and for u-boot).
  42. Deprecated properties:
  43. - g-use-dma: gadget DMA mode is automatically detected
  44. Example:
  45. usb@101c0000 {
  46. compatible = "ralink,rt3050-usb, snps,dwc2";
  47. reg = <0x101c0000 40000>;
  48. interrupts = <18>;
  49. clocks = <&usb_otg_ahb_clk>;
  50. clock-names = "otg";
  51. phys = <&usbphy>;
  52. phy-names = "usb2-phy";
  53. };
