| - "amlogic,meson-gxbb-usb": The DWC2 USB controller instance in Amlogic S905 SoCs; | |
| - "amcc,dwc-otg": The DWC2 USB controller instance in AMCC Canyonlands 460EX SoCs; | |
| - snps,dwc2: A generic DWC2 USB controller with default parameters. | |
| - "st,stm32f4x9-fsotg": The DWC2 USB FS/HS controller instance in STM32F4x9 SoCs | |
| configured in FS mode; | |
| - "st,stm32f4x9-hsotg": The DWC2 USB HS controller instance in STM32F4x9 SoCs | |
| configured in HS mode; | |
| - "st,stm32f7-hsotg": The DWC2 USB HS controller instance in STM32F7 SoCs | |
| configured in HS mode; | |
| - reg : Should contain 1 register range (address and length) | |
| - interrupts : Should contain 1 interrupt | |
| - clocks: clock provider specifier | |
| - clock-names: shall be "otg" | |
| Refer to clk/clock-bindings.txt for generic clock consumer properties | |
| Optional properties: | |
| - phys: phy provider specifier | |
| - phy-names: shall be "usb2-phy" | |
| Refer to phy/phy-bindings.txt for generic phy consumer properties | |
| - dr_mode: shall be one of "host", "peripheral" and "otg" | |
| Refer to usb/generic.txt | |
| - g-rx-fifo-size: size of rx fifo size in gadget mode. | |
| - g-np-tx-fifo-size: size of non-periodic tx fifo size in gadget mode. | |
| - g-tx-fifo-size: size of periodic tx fifo per endpoint (except ep0) in gadget mode. | |
| - usb33d-supply: external VBUS and ID sensing comparators supply, in order to | |
| perform OTG operation, used on STM32MP1 SoCs. | |
| - u-boot,force-b-session-valid: force B-peripheral session instead of relying on | |
| VBUS sensing (only valid when dr_mode = "peripheral" and for u-boot). | |
| Deprecated properties: | |
| - g-use-dma: gadget DMA mode is automatically detected | |
