1 * Renesas R-Car generation 3 USB 3.0 PHY
3 This file provides information on what the device node for the R-Car generation
4 3 USB 3.0 PHY contains.
5 If you want to enable spread spectrum clock (ssc), you should use USB_EXTAL
6 instead of USB3_CLK. However, if you don't want to these features, you don't
10 - compatible: "renesas,r8a7795-usb3-phy" if the device is a part of an R8A7795
12 "renesas,r8a7796-usb3-phy" if the device is a part of an R8A7796
14 "renesas,r8a77965-usb3-phy" if the device is a part of an
16 "renesas,rcar-gen3-usb3-phy" for a generic R-Car Gen3 compatible
19 When compatible with the generic version, nodes must list the
20 SoC-specific version corresponding to the platform first
21 followed by the generic version.
23 - reg: offset and length of the USB 3.0 PHY register block.
24 - clocks: A list of phandles and clock-specifier pairs.
25 - clock-names: Name of the clocks.
26 - The funcional clock must be "usb3-if".
27 - The usb3's external clock must be "usb3s_clk".
28 - The usb2's external clock must be "usb_extal". If you want to use the ssc,
29 the clock-frequency must not be 0.
30 - #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
33 - renesas,ssc-range: Enable/disable spread spectrum clock (ssc) by using
34 the following values as u32:
35 - 0 (or the property doesn't exist): disable the ssc
36 - 4980: enable the ssc as -4980 ppm
37 - 4492: enable the ssc as -4492 ppm
38 - 4003: enable the ssc as -4003 ppm
