| * Renesas R-Car generation 3 USB 2.0 PHY |
| |
| This file provides information on what the device node for the R-Car generation |
| 3 and RZ/G2 USB 2.0 PHY contain. |
| |
| Required properties: |
| - compatible: "renesas,usb2-phy-r8a774a1" if the device is a part of an R8A774A1 |
| 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 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 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 <0>. |
| |
| 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. |
| |
| 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>; |
| }; |
