1* Xen hypervisor device tree bindings
2
3Xen ARM virtual platforms shall have a top-level "hypervisor" node with
4the 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.

18
19Example (assuming #address-cells = <2> and #size-cells = <2>):
20
21hypervisor {
22	compatible = "xen,xen-4.3", "xen,xen";
23	reg = <0 0xb0000000 0 0x20000>;
24	interrupts = <1 15 0xf08>;
25};
