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
|
- "brcm,bcm7445-xhci" for Broadcom STB SoCs with XHCI
|
- "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
|
- quirk-skip-phy-init: indicate that do not manage the PHY state in the HCD core
|
and handle this in the controller's driver.
|
- imod-interval-ns: default interrupt moderation interval is 5000ns
|
- phys : see usb-hcd.yaml in the current directory
|
- offload: supporting USB offload feature, 0: disabled, 1: audio
|
|
additionally the properties from usb-hcd.yaml (in the current directory) are
|
supported.
|
|
|
Example:
|
usb@f0931000 {
|
compatible = "generic-xhci";
|
reg = <0xf0931000 0x8c8>;
|
interrupts = <0x0 0x4e 0x0>;
|
};
