1* Renesas R-Car generation 3 USB 2.0 PHY
2
3This file provides information on what the device node for the R-Car generation
43, RZ/G1C, RZ/G2 and RZ/A2 USB 2.0 PHY contain.
5
6Required properties:
7- compatible: "renesas,usb2-phy-r7s9210" if the device is a part of an R7S9210
8	      SoC.
9	      "renesas,usb2-phy-r8a77470" if the device is a part of an R8A77470
10	      SoC.
11	      "renesas,usb2-phy-r8a774a1" if the device is a part of an R8A774A1
12	      SoC.
13	      "renesas,usb2-phy-r8a774c0" if the device is a part of an R8A774C0
14	      SoC.
15	      "renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
16	      SoC.
17	      "renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
18	      SoC.
19	      "renesas,usb2-phy-r8a77965" if the device is a part of an
20	      R8A77965 SoC.
21	      "renesas,usb2-phy-r8a77990" if the device is a part of an
22	      R8A77990 SoC.
23	      "renesas,usb2-phy-r8a77995" if the device is a part of an
24	      R8A77995 SoC.
25	      "renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3, RZ/G2 or
26	      RZ/A2 compatible device.
27
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.
31
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).
36
37The 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)
41
42Optional properties:
43To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
44combined, the device tree node should set interrupt properties to use the
45channel as USB OTG:
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
50		       otg pins.
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.

55Example (R-Car H3):
56
57	usb-phy@ee080200 {
58		compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
59		reg = <0 0xee080200 0 0x700>;
60		interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
61		clocks = <&cpg CPG_MOD 703>;
62	};
63
64	usb-phy@ee0a0200 {
65		compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
66		reg = <0 0xee0a0200 0 0x700>;
67		clocks = <&cpg CPG_MOD 702>;
68	};
