-* Renesas R-Car generation 3 USB 2.0 PHY
-
-This file provides information on what the device node for the R-Car generation
-3, RZ/G1C, RZ/G2 and RZ/A2 USB 2.0 PHY contain.
-
-Required properties:
-- compatible: "renesas,usb2-phy-r7s9210" if the device is a part of an R7S9210
- SoC.
- "renesas,usb2-phy-r8a77470" if the device is a part of an R8A77470
- SoC.
- "renesas,usb2-phy-r8a774a1" if the device is a part of an R8A774A1
- SoC.
- "renesas,usb2-phy-r8a774b1" if the device is a part of an R8A774B1
- SoC.
- "renesas,usb2-phy-r8a774c0" if the device is a part of an R8A774C0
- SoC.
- "renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
- SoC.
- "renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
- SoC.
- "renesas,usb2-phy-r8a77965" if the device is a part of an
- R8A77965 SoC.
- "renesas,usb2-phy-r8a77990" if the device is a part of an
- R8A77990 SoC.
- "renesas,usb2-phy-r8a77995" if the device is a part of an
- R8A77995 SoC.
- "renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3, RZ/G2 or
- RZ/A2 compatible device.
-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first
- followed by the generic version.
-
-- reg: offset and length of the partial USB 2.0 Host register block.
-- clocks: clock phandle and specifier pair(s).
-- #phy-cells: see phy-bindings.txt in the same directory, must be <1> (and
- using <0> is deprecated).
-
-The phandle's argument in the PHY specifier is the INT_STATUS bit of controller:
-- 1 = USBH_INTA (OHCI)
-- 2 = USBH_INTB (EHCI)
-- 3 = UCOM_INT (OTG and BC)
-
-Optional properties:
-To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
-combined, the device tree node should set interrupt properties to use the
-channel as USB OTG:
-- interrupts: interrupt specifier for the PHY.
-- vbus-supply: Phandle to a regulator that provides power to the VBUS. This
- regulator will be managed during the PHY power on/off sequence.
-- renesas,no-otg-pins: boolean, specify when a board does not provide proper
- otg pins.
-- dr_mode: string, indicates the working mode for the PHY. Can be "host",
- "peripheral", or "otg". Should be set if otg controller is not used.
-
-
-Example (R-Car H3):
-
- usb-phy@ee080200 {
- compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
- reg = <0 0xee080200 0 0x700>;
- interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cpg CPG_MOD 703>;
- };
-
- usb-phy@ee0a0200 {
- compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
- reg = <0 0xee0a0200 0 0x700>;
- clocks = <&cpg CPG_MOD 702>;
- };
