- - "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
- - "renesas,usbhs-r8a7796" for r8a7796 (R-Car M3-W) compatible device
- - "renesas,usbhs-r8a77965" for r8a77965 (R-Car M3-N) compatible device
- - "renesas,usbhs-r8a77990" for r8a77990 (R-Car E3) compatible device
- - "renesas,usbhs-r8a77995" for r8a77995 (R-Car D3) compatible device
- - "renesas,usbhs-r7s72100" for r7s72100 (RZ/A1) compatible device
- - "renesas,usbhs-r7s9210" for r7s9210 (RZ/A2) compatible device
- - "renesas,rcar-gen2-usbhs" for R-Car Gen2 or RZ/G1 compatible devices

- - "renesas,rza2-usbhs" for RZ/A2 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.
- - In case of "renesas,rcar-gen3-usbhs", two clocks are required.
- First clock should be peripheral and second one should be host.
- - In case of except above, one clock is required. First clock
- should be peripheral.
-
-Optional properties:
- - renesas,buswait: Integer to use BUSWAIT register
- - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
- function should be enabled
- - phys: phandle + phy specifier pair
- - phy-names: must be "usb"
- - dmas: Must contain a list of references to DMA specifiers.
- - dma-names : named "ch%d", where %d is the channel number ranging from zero
- to the number of channels (DnFIFOs) minus one.
-
-Example:
- usbhs: usb@e6590000 {
- compatible = "renesas,usbhs-r8a7790", "renesas,rcar-gen2-usbhs";
- reg = <0 0xe6590000 0 0x100>;
- interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
- };
