* QEMU PVPANIC MMIO Configuration bindings
QEMU's emulation / virtualization targets provide the following PVPANIC
MMIO Configuration interface on the "virt" machine.
- a read-write, 16-bit wide data register.
QEMU exposes the data register to guests as memory mapped registers.
Required properties:
- compatible: "qemu,pvpanic-mmio".
- reg: the MMIO region used by the device.
* Bytes 0x0 Write panic event to the reg when guest OS panics.
* Bytes 0x1 Reserved.
