-Binding for the Cadence USBSS-DRD controller
-
-Required properties:
- - reg: Physical base address and size of the controller's register areas.
- Controller has 3 different regions:
- - HOST registers area
- - DEVICE registers area
- - OTG/DRD registers area
- - reg-names - register memory area names:
- "xhci" - for HOST registers space
- "dev" - for DEVICE registers space
- "otg" - for OTG/DRD registers space
- - compatible: Should contain: "cdns,usb3"
- - interrupts: Interrupts used by cdns3 controller:
- "host" - interrupt used by XHCI driver.
- "peripheral" - interrupt used by device driver
- "otg" - interrupt used by DRD/OTG part of driver
-
-Optional properties:
- - maximum-speed : valid arguments are "super-speed", "high-speed" and
- "full-speed"; refer to usb/generic.txt
- - dr_mode: Should be one of "host", "peripheral" or "otg".
- - phys: reference to the USB PHY
- - phy-names: from the *Generic PHY* bindings;
- Supported names are:
- - cdns3,usb2-phy
- - cdns3,usb3-phy
-
- - cdns,on-chip-buff-size : size of memory intended as internal memory for endpoints
- buffers expressed in KB
-
-Example:
- usb@f3000000 {
- compatible = "cdns,usb3";
- interrupts = <GIC_USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_USB_IRQ 8 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "host", "peripheral", "otg";
- reg = <0xf3000000 0x10000>, /* memory area for HOST registers */
- <0xf3010000 0x10000>, /* memory area for DEVICE registers */
- <0xf3020000 0x10000>; /* memory area for OTG/DRD registers */
- reg-names = "xhci", "dev", "otg";
- phys = <&usb2_phy>, <&usb3_phy>;
- phy-names = "cdns3,usb2-phy", "cnds3,usb3-phy";
- };
