-Renesas Electronics USB3.0 Peripheral driver
-
-Required properties:
- - compatible: Must contain one of the following:
- - "renesas,r8a774a1-usb3-peri"
- - "renesas,r8a774b1-usb3-peri"
- - "renesas,r8a774c0-usb3-peri"
- - "renesas,r8a7795-usb3-peri"
- - "renesas,r8a7796-usb3-peri"
- - "renesas,r8a77965-usb3-peri"
- - "renesas,r8a77990-usb3-peri"
- - "renesas,rcar-gen3-usb3-peri" for a generic R-Car Gen3 or RZ/G2
- 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 USB3.0 Peripheral
- - interrupts: Interrupt specifier for the USB3.0 Peripheral
- - clocks: clock phandle and specifier pair
-
-Optional properties:
- - phys: phandle + phy specifier pair
- - phy-names: must be "usb"
- - usb-role-switch: support role switch. see usb/generic.txt
-
-Sub-nodes:
-- any connector to the data bus of this controller should be modelled using the
- OF graph bindings specified in bindings/graph.txt, if the "usb-role-switch"
- property is used.
-
-Example of R-Car H3 ES1.x:
- usb3_peri0: usb@ee020000 {
- compatible = "renesas,r8a7795-usb3-peri",
- "renesas,rcar-gen3-usb3-peri";
- reg = <0 0xee020000 0 0x400>;
- interrupts = <GIC_SPI 104 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cpg CPG_MOD 328>;
- };
-
- usb3_peri1: usb@ee060000 {
- compatible = "renesas,r8a7795-usb3-peri",
- "renesas,rcar-gen3-usb3-peri";
- reg = <0 0xee060000 0 0x400>;
- interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cpg CPG_MOD 327>;

-Example of RZ/G2E:
