1 * Renesas R-Car generation 3 USB 2.0 PHY
3 This file provides information on what the device node for the R-Car generation
4 3, RZ/G1C, RZ/G2 and RZ/A2 USB 2.0 PHY contain.
7 - compatible: "renesas,usb2-phy-r7s9210" if the device is a part of an R7S9210
9 "renesas,usb2-phy-r8a77470" if the device is a part of an R8A77470
11 "renesas,usb2-phy-r8a774a1" if the device is a part of an R8A774A1
13 "renesas,usb2-phy-r8a774c0" if the device is a part of an R8A774C0
15 "renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
17 "renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
19 "renesas,usb2-phy-r8a77965" if the device is a part of an
21 "renesas,usb2-phy-r8a77990" if the device is a part of an
23 "renesas,usb2-phy-r8a77995" if the device is a part of an
25 "renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3, RZ/G2 or
26 RZ/A2 compatible device.
28 When compatible with the generic version, nodes must list the
29 SoC-specific version corresponding to the platform first
30 followed by the generic version.
32 - reg: offset and length of the partial USB 2.0 Host register block.
33 - clocks: clock phandle and specifier pair(s).
34 - #phy-cells: see phy-bindings.txt in the same directory, must be <1> (and
35 using <0> is deprecated).
37 The phandle's argument in the PHY specifier is the INT_STATUS bit of controller:
38 - 1 = USBH_INTA (OHCI)
39 - 2 = USBH_INTB (EHCI)
40 - 3 = UCOM_INT (OTG and BC)
43 To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
44 combined, the device tree node should set interrupt properties to use the
46 - interrupts: interrupt specifier for the PHY.
47 - vbus-supply: Phandle to a regulator that provides power to the VBUS. This
48 regulator will be managed during the PHY power on/off sequence.
49 - renesas,no-otg-pins: boolean, specify when a board does not provide proper
51 - dr_mode: string, indicates the working mode for the PHY. Can be "host",
52 "peripheral", or "otg". Should be set if otg controller is not used.
