1 * Renesas R-Car generation 2 USB PHY
3 This file provides information on what the device node for the R-Car generation
7 - compatible: "renesas,usb-phy-r8a7743" if the device is a part of R8A7743 SoC.
8 "renesas,usb-phy-r8a7744" if the device is a part of R8A7744 SoC.
9 "renesas,usb-phy-r8a7745" if the device is a part of R8A7745 SoC.
10 "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.
11 "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
12 "renesas,usb-phy-r8a7794" if the device is a part of R8A7794 SoC.
13 "renesas,rcar-gen2-usb-phy" for a generic R-Car Gen2 or
14 RZ/G1 compatible device.
16 When compatible with the generic version, nodes must list the
17 SoC-specific version corresponding to the platform first
18 followed by the generic version.
20 - reg: offset and length of the register block.
21 - #address-cells: number of address cells for the USB channel subnodes, must
23 - #size-cells: number of size cells for the USB channel subnodes, must be <0>.
24 - clocks: clock phandle and specifier pair.
25 - clock-names: string, clock input name, must be "usbhs".
27 The USB PHY device tree node should have the subnodes corresponding to the USB
28 channels. These subnodes must contain the following properties:
29 - reg: the USB controller selector; see the table below for the values.
30 - #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
32 The phandle's argument in the PHY specifier is the USB controller selector for
33 the USB channel; see the selector meanings below:
35 +-----------+---------------+---------------+
39 +-----------+---------------+---------------+
40 | 0 | PCI EHCI/OHCI | HS-USB |
41 | 2 | PCI EHCI/OHCI | xHCI |
42 +-----------+---------------+---------------+
44 Example (Lager board):
47 compatible = "renesas,usb-phy-r8a7790", "renesas,rcar-gen2-usb-phy";
48 reg = <0 0xe6590100 0 0x100>;
51 clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
52 clock-names = "usbhs";
