Required properties:
- compatible: "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,rcar-gen3-usb2-phy" for a generic R-Car Gen3 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>.
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.
Example (R-Car H3):
usb-phy@ee080200 {
- compatible = "renesas,usb2-phy-r8a7795";
+ compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
reg = <0 0xee080200 0 0x700>;
interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp7_clks R8A7795_CLK_EHCI0>;
+ clocks = <&cpg CPG_MOD 703>;
};
usb-phy@ee0a0200 {
- compatible = "renesas,usb2-phy-r8a7795";
+ compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
reg = <0 0xee0a0200 0 0x700>;
- clocks = <&mstp7_clks R8A7795_CLK_EHCI0>;
+ clocks = <&cpg CPG_MOD 702>;
