-* Renesas R-Car generation 3 USB 3.0 PHY
-
-This file provides information on what the device node for the R-Car generation
-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,r8a774a1-usb3-phy" if the device is a part of an R8A774A1
- SoC.
- "renesas,r8a774b1-usb3-phy" if the device is a part of an R8A774B1
- 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 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: 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";
- };
