| Generic USB Device Properties |
| |
| Usually, we only use device tree for hard wired USB device. |
| The reference binding doc is from: |
| http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps |
| |
| |
| Required properties: |
| - compatible: "usbVID,PID", where VID is the vendor id and PID the product id. |
| The textual representation of VID and PID shall be in lower case hexadecimal |
| with leading zeroes suppressed. The other compatible strings from the above |
| standard binding could also be used, but a device adhering to this binding |
| may leave out all except for "usbVID,PID". |
| - reg: the number of the USB hub port or the USB host-controller port to which |
| this device is attached. The range is 1-255. |
| |
| |
| Required properties for hub nodes with device nodes: |
| - #address-cells: shall be 1 |
| - #size-cells: shall be 0 |
| |
| |
| Required properties for host-controller nodes with device nodes: |
| - #address-cells: shall be 1 |
| - #size-cells: shall be 0 |
| |
| |
| Example: |
| |
| &usb1 { /* host controller */ |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| hub@1 { /* hub connected to port 1 */ |
| compatible = "usb5e3,608"; |
| reg = <1>; |
| }; |
| }; |
