| 13 | Firmwares or hypervisors can use this devicetree to describe an |
| 14 | interrupt and a shared resource to inject a Virtual Machine Generation ID. |
| 15 | Virtual Machine Generation ID is a globally unique identifier (GUID) and |
| 16 | the devicetree binding follows VMGenID specification defined in |
| 17 | http://go.microsoft.com/fwlink/?LinkId=260709. |
