    1 * QEMU PVPANIC MMIO Configuration bindings
    2 
    3 QEMU's emulation / virtualization targets provide the following PVPANIC
    4 MMIO Configuration interface on the "virt" machine.
    5 type:
    6 
    7 - a read-write, 16-bit wide data register.
    8 
    9 QEMU exposes the data register to guests as memory mapped registers.
   10 
   11 Required properties:
   12 
   13 - compatible: "qemu,pvpanic-mmio".
   14 - reg: the MMIO region used by the device.

   20 / {
   21         #size-cells = <0x2>;
   22         #address-cells = <0x2>;
   23 
   24         pvpanic-mmio@9060000 {
   25                 compatible = "qemu,pvpanic-mmio";
   26                 reg = <0x0 0x9060000 0x0 0x2>;
