* 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>;

* Renesas R-Car generation 3 USB 3.0 PHY
This file provides information on what the device node for the R-Car generation
3 and RZ/G2 USB 3.0 PHY contain.
If you want to enable spread spectrum clock (ssc), you should use USB_EXTAL
instead of USB3_CLK. However, if you don't want to these features, you don't
need this driver.
Required properties:
- compatible: "renesas,r8a774a1-usb3-phy" if the device is a part of an R8A774A1
SoC.
"renesas,r8a774b1-usb3-phy" if the device is a part of an R8A774B1
SoC.
"renesas,r8a7795-usb3-phy" if the device is a part of an R8A7795
SoC.
"renesas,r8a7796-usb3-phy" if the device is a part of an R8A7796
SoC.
"renesas,r8a77965-usb3-phy" if the device is a part of an
R8A77965 SoC.
"renesas,rcar-gen3-usb3-phy" for a generic R-Car Gen3 or RZ/G2
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 USB 3.0 PHY register block.
- clocks: A list of phandles and clock-specifier pairs.
- clock-names: Name of the clocks.
- The funcional clock must be "usb3-if".
- The usb3's external clock must be "usb3s_clk".
- The usb2's external clock must be "usb_extal". If you want to use the ssc,
the clock-frequency must not be 0.
- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
Optional properties:
- renesas,ssc-range: Enable/disable spread spectrum clock (ssc) by using
the following values as u32:
- 0 (or the property doesn't exist): disable the ssc
- 4980: enable the ssc as -4980 ppm
- 4492: enable the ssc as -4492 ppm
- 4003: enable the ssc as -4003 ppm
Example (R-Car H3):
usb-phy@e65ee000 {
compatible = "renesas,r8a7795-usb3-phy",
"renesas,rcar-gen3-usb3-phy";
reg = <0 0xe65ee000 0 0x90>;
clocks = <&cpg CPG_MOD 328>, <&usb3s0_clk>, <&usb_extal>;
clock-names = "usb3-if", "usb3s_clk", "usb_extal";
