1	* Xen hypervisor device tree bindings
2	
3	Xen ARM virtual platforms shall have a top-level "hypervisor" node with
4	the following properties:
5	
6	- compatible:
7		compatible = "xen,xen-<version>", "xen,xen";
8	  where <version> is the version of the Xen ABI of the platform.
9	
10	- reg: specifies the base physical address and size of a region in
11	  memory where the grant table should be mapped to, using an
12	  HYPERVISOR_memory_op hypercall. The memory region is large enough to map
13	  the whole grant table (it is larger or equal to gnttab_max_grant_frames()).
14	
15	- interrupts: the interrupt used by Xen to inject event notifications.
16	  A GIC node is also required.
17	
18	
19	Example (assuming #address-cells = <2> and #size-cells = <2>):
20	
21	hypervisor {
22		compatible = "xen,xen-4.3", "xen,xen";
23		reg = <0 0xb0000000 0 0x20000>;
24		interrupts = <1 15 0xf08>;
25	};
