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-r8a7790" if the device is a part of R8A7790 SoC.
8 "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
9 - reg: offset and length of the register block.
10 - #address-cells: number of address cells for the USB channel subnodes, must
12 - #size-cells: number of size cells for the USB channel subnodes, must be <0>.
13 - clocks: clock phandle and specifier pair.
14 - clock-names: string, clock input name, must be "usbhs".
16 The USB PHY device tree node should have the subnodes corresponding to the USB
17 channels. These subnodes must contain the following properties:
18 - reg: the USB controller selector; see the table below for the values.
19 - #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
21 The phandle's argument in the PHY specifier is the USB controller selector for
22 the USB channel; see the selector meanings below:
24 +-----------+---------------+---------------+
28 +-----------+---------------+---------------+
29 | 0 | PCI EHCI/OHCI | HS-USB |
30 | 2 | PCI EHCI/OHCI | xHCI |
31 +-----------+---------------+---------------+
33 Example (Lager board):
36 compatible = "renesas,usb-phy-r8a7790";
37 reg = <0 0xe6590100 0 0x100>;
40 clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
41 clock-names = "usbhs";
