+* 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.
+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
+ SoC.
+ "renesas,r8a7796-usb3-phy" if the device is a part of an R8A7796
+ SoC.
+ "renesas,rcar-gen3-usb3-phy" 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: offset and length of the USB 3.0 PHY register block.
+- clocks: A list of phandles and clock-specifier pairs.
+- clock-names: Name of the clocks.
+ - The funcional clock must be "usb3-if".
+ - The usb3's external clock must be "usb3s_clk".
+ - The usb2's external clock must be "usb_extal". If you want to use the ssc,
+ the clock-frequency must not be 0.
+- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
+
+Optional properties:
+- renesas,ssc-range: Enable/disable spread spectrum clock (ssc) by using
+ the following values as u32:
+ - 0 (or the property doesn't exist): disable the ssc
+ - 4980: enable the ssc as -4980 ppm
+ - 4492: enable the ssc as -4492 ppm
+ - 4003: enable the ssc as -4003 ppm
+
+Example (R-Car H3):
+
+ usb-phy@e65ee000 {
+ compatible = "renesas,r8a7795-usb3-phy",
+ "renesas,rcar-gen3-usb3-phy";
+ reg = <0 0xe65ee000 0 0x90>;
+ clocks = <&cpg CPG_MOD 328>, <&usb3s0_clk>, <&usb_extal>;
+ clock-names = "usb3-if", "usb3s_clk", "usb_extal";
+ };
