12*612bd01fSOctavian PurdilaDescription:
13*612bd01fSOctavian Purdila
14*612bd01fSOctavian Purdila		This group contains the configuration for user defined ACPI
15*612bd01fSOctavian Purdila		tables. The attributes of a user define table are:
16*612bd01fSOctavian Purdila
17*612bd01fSOctavian Purdila		aml 		- a binary attribute that the user can use to
18*612bd01fSOctavian Purdila				fill in the ACPI aml definitions. Once the aml
19*612bd01fSOctavian Purdila				data is written to this file and the file is
20*612bd01fSOctavian Purdila				closed the table will be loaded and ACPI devices
21*612bd01fSOctavian Purdila				will be enumerated. To check if the operation is
22*612bd01fSOctavian Purdila				successful the user must check the error code
23*612bd01fSOctavian Purdila				for close(). If the operation is successful,
24*612bd01fSOctavian Purdila				subsequent writes to this attribute will fail.
25*612bd01fSOctavian Purdila
26*612bd01fSOctavian Purdila		The rest of the attributes are read-only and are valid only
27*612bd01fSOctavian Purdila		after the table has been loaded by filling the aml entry:
28*612bd01fSOctavian Purdila
29*612bd01fSOctavian Purdila		signature 	- ASCII table signature
30*612bd01fSOctavian Purdila		length 		- length of table in bytes, including the header
31*612bd01fSOctavian Purdila		revision 	- ACPI Specification minor version number
32*612bd01fSOctavian Purdila		oem_id 		- ASCII OEM identification
33*612bd01fSOctavian Purdila		oem_table_id 	- ASCII OEM table identification
34*612bd01fSOctavian Purdila		oem_revision 	- OEM revision number
35*612bd01fSOctavian Purdila		asl_compiler_id - ASCII ASL compiler vendor ID
36*612bd01fSOctavian Purdila		asl_compiler_revision - ASL compiler version
