Renesas Electronics USB3.0 Peripheral driver
Required properties:
- compatible: Must contain one of the following:
- "renesas,r8a7795-usb3-peri"
- 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
Example:
usb3_peri0: usb@ee020000 {
compatible = "renesas,r8a7795-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";
reg = <0 0xee060000 0 0x400>;
interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cpg CPG_MOD 327>;
};
