| USB xHCI controllers |
| |
| Required properties: |
| - compatible: should be one or more of |
| |
| - "generic-xhci" for generic XHCI device |
| - "marvell,armada3700-xhci" for Armada 37xx SoCs |
| - "marvell,armada-375-xhci" for Armada 375 SoCs |
| - "marvell,armada-380-xhci" for Armada 38x SoCs |
| - "renesas,xhci-r8a7743" for r8a7743 SoC |
| - "renesas,xhci-r8a7744" for r8a7744 SoC |
| - "renesas,xhci-r8a774a1" for r8a774a1 SoC |
| - "renesas,xhci-r8a7790" for r8a7790 SoC |
| - "renesas,xhci-r8a7791" for r8a7791 SoC |
| - "renesas,xhci-r8a7793" for r8a7793 SoC |
| - "renesas,xhci-r8a7795" for r8a7795 SoC |
| - "renesas,xhci-r8a7796" for r8a7796 SoC |
| - "renesas,xhci-r8a77965" for r8a77965 SoC |
| - "renesas,xhci-r8a77990" for r8a77990 SoC |
| - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 or RZ/G1 compatible |
| device |
| - "renesas,rcar-gen3-xhci" for a generic R-Car Gen3 or RZ/G2 compatible |
| device |
| - "xhci-platform" (deprecated) |
| |
| When compatible with the generic version, nodes must list the |
| SoC-specific version corresponding to the platform first |
| followed by the generic version. |
| |
| - reg: should contain address and length of the standard XHCI |
| register set for the device. |
| - interrupts: one XHCI interrupt should be described here. |
| |
| Optional properties: |
| - clocks: reference to the clocks |
| - clock-names: mandatory if there is a second clock, in this case |
| the name must be "core" for the first clock and "reg" for the |
| second one |
| - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM |
| - usb3-lpm-capable: determines if platform is USB3 LPM capable |
| - quirk-broken-port-ped: set if the controller has broken port disable mechanism |
| - imod-interval-ns: default interrupt moderation interval is 5000ns |
| - phys : see usb-hcd.txt in the current directory |
| |
| additionally the properties from usb-hcd.txt (in the current directory) are |
| supported. |
| |
| |
| Example: |
| usb@f0931000 { |
| compatible = "generic-xhci"; |
| reg = <0xf0931000 0x8c8>; |
| interrupts = <0x0 0x4e 0x0>; |
| }; |
