                As described in IEEE Std 1275-1994, but must provide at least a
                definition of non-prefetchable memory. One or both of prefetchable Memory
                and IO Space may also be provided.



             This property is **required**.

           - .. code-block:: none

                Used to supply OSPM with the device’s PNP ID or ACPI ID. A node is consder as acpi based or not based on whether this property is present or not.


         * - ``acpi-uid``
           - ``string``
           - .. code-block:: none

                Provides OSPM with a logical device ID that does not change
                across reboots. This object is optional, but is required when the device
                has no other way to report a persistent unique device ID. The _UID must be
                unique across all devices with either a common _HID or _CID.
