+Description:
+ The /sys/devices/ directory contains a sub-directory for each
+ System-on-Chip (SoC) device on a running platform. Information
+ regarding each SoC can be obtained by reading sysfs files. This
+ functionality is only available if implemented by the platform.
+
+ The directory created for each SoC will also house information
+ about devices which are commonly contained in /sys/devices/platform.
+ It has been agreed that if an SoC device exists, its supported
+ devices would be better suited to appear as children of that SoC.
+
+What: /sys/devices/socX/machine
+Date: October 2011
+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ Read-only attribute common to all SoCs. Contains the SoC machine
+ name (e.g. Ux500).
+
+What: /sys/devices/socX/family
+Date: October 2011
+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ Read-only attribute common to all SoCs. Contains SoC family name
+ (e.g. DB8500).
+
+What: /sys/devices/socX/soc_id
+Date: October 2011
+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ Read-only attribute supported by most SoCs. In the case of
+ ST-Ericsson's chips this contains the SoC serial number.
+
+What: /sys/devices/socX/revision
+Date: October 2011
+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ Read-only attribute supported by most SoCs. Contains the SoC's
+ manufacturing revision number.
+
+What: /sys/devices/socX/process
+Date: October 2011
+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ Read-only attribute supported ST-Ericsson's silicon. Contains the
+ the process by which the silicon chip was manufactured.
