3	Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>
4	Description:
5			This attribute indicates the full path of ACPI namespace
6			object associated with the device object.  For example,
7			\_SB_.PCI0.
8			This file is not present for device objects representing
9			fixed ACPI hardware features (like power and sleep
10			buttons).

14	Contact:	Rafael J. Wysocki <rjw@rjwysocki.net>
15	Description:
16			This attribute indicates the PNP IDs of the device object.
17			That is acpi:HHHHHHHH:[CCCCCCC:].  Where each HHHHHHHH or
18			CCCCCCCC contains device object's PNPID (_HID or _CID).
