19  - "st,stm32f4x9-fsotg": The DWC2 USB FS/HS controller instance in STM32F4x9 SoCs
20  configured in FS mode;
21  - "st,stm32f4x9-hsotg": The DWC2 USB HS controller instance in STM32F4x9 SoCs
22  configured in HS mode;
23  - "st,stm32f7-hsotg": The DWC2 USB HS controller instance in STM32F7 SoCs
24    configured in HS mode;
25- reg : Should contain 1 register range (address and length)
26- interrupts : Should contain 1 interrupt
27- clocks: clock provider specifier
28- clock-names: shall be "otg"
29Refer to clk/clock-bindings.txt for generic clock consumer properties
30
31Optional properties:
32- phys: phy provider specifier
33- phy-names: shall be "usb2-phy"
34Refer to phy/phy-bindings.txt for generic phy consumer properties
35- dr_mode: shall be one of "host", "peripheral" and "otg"
36  Refer to usb/generic.txt
37- g-rx-fifo-size: size of rx fifo size in gadget mode.
38- g-np-tx-fifo-size: size of non-periodic tx fifo size in gadget mode.
39- g-tx-fifo-size: size of periodic tx fifo per endpoint (except ep0) in gadget mode.
40- usb33d-supply: external VBUS and ID sensing comparators supply, in order to
41  perform OTG operation, used on STM32MP1 SoCs.
42- u-boot,force-b-session-valid: force B-peripheral session instead of relying on
43  VBUS sensing (only valid when dr_mode = "peripheral" and for u-boot).
44
45Deprecated properties:
46- g-use-dma: gadget DMA mode is automatically detected
