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:
usb3_peri0: usb@ee020000 {
compatible = "renesas,r8a774c0-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>;
companion = <&xhci0>;
usb-role-switch;
port {
usb3_role_switch: endpoint {
remote-endpoint = <&hd3ss3220_ep>;
};
};
};
