1	What:		/sys/devices/socX
2	Date:		January 2012
3	contact:	Lee Jones <lee.jones@linaro.org>
4	Description:
5			The /sys/devices/ directory contains a sub-directory for each
6			System-on-Chip (SoC) device on a running platform. Information
7			regarding each SoC can be obtained by reading sysfs files. This
8			functionality is only available if implemented by the platform.
9	
10			The directory created for each SoC will also house information
11			about devices which are commonly contained in /sys/devices/platform.
12			It has been agreed that if an SoC device exists, its supported
13			devices would be better suited to appear as children of that SoC.
14	
15	What:		/sys/devices/socX/machine
16	Date:		January 2012
17	contact:	Lee Jones <lee.jones@linaro.org>
18	Description:
19			Read-only attribute common to all SoCs. Contains the SoC machine
20			name (e.g. Ux500).
21	
22	What:		/sys/devices/socX/family
23	Date:		January 2012
24	contact:	Lee Jones <lee.jones@linaro.org>
25	Description:
26			Read-only attribute common to all SoCs. Contains SoC family name
27			(e.g. DB8500).
28	
29	What:		/sys/devices/socX/soc_id
30	Date:		January 2012
31	contact:	Lee Jones <lee.jones@linaro.org>
32	Description:
33			Read-only attribute supported by most SoCs. In the case of
34			ST-Ericsson's chips this contains the SoC serial number.
35	
36	What:		/sys/devices/socX/revision
37	Date:		January 2012
38	contact:	Lee Jones <lee.jones@linaro.org>
39	Description:
40			Read-only attribute supported by most SoCs. Contains the SoC's
41			manufacturing revision number.
42	
43	What:		/sys/devices/socX/process
44	Date:		January 2012
45	contact:	Lee Jones <lee.jones@linaro.org>
46	Description:
47			Read-only attribute supported ST-Ericsson's silicon. Contains the
48			the process by which the silicon chip was manufactured.
49	
50	What:		/sys/bus/soc
51	Date:		January 2012
52	contact:	Lee Jones <lee.jones@linaro.org>
53	Description:
54			The /sys/bus/soc/ directory contains the usual sub-folders
55			expected under most buses. /sys/bus/soc/devices is of particular
56			interest, as it contains a symlink for each SoC device found on
57			the system. Each symlink points back into the aforementioned
58			/sys/devices/socX devices.
