- compatible: Must contain one or more of the following:
- "renesas,usbhs-r8a7790" for r8a7790 (R-Car H2) compatible device
- "renesas,usbhs-r8a7791" for r8a7791 (R-Car M2-W) compatible device
- "renesas,usbhs-r8a7794" for r8a7794 (R-Car E2) compatible device
- "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
- "renesas,rcar-gen2-usbhs" for R-Car Gen2 compatible device
- "renesas,rcar-gen3-usbhs" for R-Car Gen3 compatible device
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first followed
by the generic version.
- reg: Base address and length of the register for the USBHS
- interrupts: Interrupt specifier for the USBHS
- clocks: A list of phandle + clock specifier pairs
