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";
|
||||
};
