This patch adds support for R-Car M3-W. This patch also adds R-Car
Gen3 generic version's compatible and changes ".compatible" in

@ -3,20 +3,30 @@ Renesas Electronics USB3.0 Peripheral driver
Required properties:
- compatible: Must contain one of the following:
- "renesas,r8a7795-usb3-peri"
- "renesas,r8a7796-usb3-peri"
- "renesas,rcar-gen3-usb3-peri" for a generic 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 USB3.0 Peripheral
- interrupts: Interrupt specifier for the USB3.0 Peripheral
- clocks: clock phandle and specifier pair
Example:
Example of R-Car H3 ES1.x:
usb3_peri0: usb@ee020000 {
compatible = "renesas,r8a7795-usb3-peri";
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";
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>;
