    Subject[PATCH v4 06/24] docs: Xen ARM DT bindings
    Date
    Add a doc to describe the Xen ARM device tree bindings


    Changes in v4:

    - "xen,xen" should be last as it is less specific;
    - update reg property using 2 address-cells and 2 size-cells.

    +* Xen hypervisor device tree bindings
    +
    +Xen ARM virtual platforms shall have the following properties:
    +
    +- compatible:
    + compatible = "xen,xen-<version>", "xen,xen";
    + where <version> is the version of the Xen ABI of the platform.
    +
    +- reg: specifies the base physical address and size of a region in
    + memory where the grant table should be mapped to, using an
    + HYPERVISOR_memory_op hypercall.
    +
    +- interrupts: the interrupt used by Xen to inject event notifications.
    +
    +
    +Example:
    +
    +hypervisor {
    + compatible = "xen,xen-4.3", "xen,xen";
    + reg = <0 0xb0000000 0 0x20000>;
    + interrupts = <1 15 0xf08>;
    +};
