* Renesas R-Car generation 3 USB 3.0 PHY
This file provides information on what the device node for the R-Car generation
3 USB 3.0 PHY contains.
3 and RZ/G2 USB 3.0 PHY contain.
If you want to enable spread spectrum clock (ssc), you should use USB_EXTAL
instead of USB3_CLK. However, if you don't want to these features, you don't
need this driver.
Required properties:
- compatible: "renesas,r8a7795-usb3-phy" if the device is a part of an R8A7795
- compatible: "renesas,r8a774a1-usb3-phy" if the device is a part of an R8A774A1
SoC.
"renesas,r8a7795-usb3-phy" if the device is a part of an R8A7795
SoC.
"renesas,r8a7796-usb3-phy" if the device is a part of an R8A7796
SoC.
"renesas,r8a77965-usb3-phy" if the device is a part of an
R8A77965 SoC.
"renesas,rcar-gen3-usb3-phy" for a generic R-Car Gen3 compatible
device.
"renesas,rcar-gen3-usb3-phy" 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
