-* QEMU PVPANIC MMIO Configuration bindings
-
-QEMU's emulation / virtualization targets provide the following PVPANIC
-MMIO Configuration interface on the "virt" machine.
-type:
-
-- 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.
-
-Example:
-
-/ {
- #size-cells = <0x2>;
- #address-cells = <0x2>;
-
- pvpanic-mmio@9060000 {
- compatible = "qemu,pvpanic-mmio";
- reg = <0x0 0x9060000 0x0 0x2>;
- };
-};
