-What: /sys/devices/socX
-Date: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-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: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-Description:
- Read-only attribute common to all SoCs. Contains the SoC machine
- name (e.g. Ux500).
-
-What: /sys/devices/socX/family
-Date: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-Description:
- Read-only attribute common to all SoCs. Contains SoC family name
- (e.g. DB8500).
-
-What: /sys/devices/socX/soc_id
-Date: January 2012
-contact: Lee Jones <lee.jones@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: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-Description:
- Read-only attribute supported by most SoCs. Contains the SoC's
- manufacturing revision number.
-
-What: /sys/devices/socX/process
-Date: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-Description:
- Read-only attribute supported ST-Ericsson's silicon. Contains the
- the process by which the silicon chip was manufactured.
-
-What: /sys/bus/soc
-Date: January 2012
-contact: Lee Jones <lee.jones@linaro.org>
-Description:
- The /sys/bus/soc/ directory contains the usual sub-folders
- expected under most buses. /sys/bus/soc/devices is of particular
- interest, as it contains a symlink for each SoC device found on
- the system. Each symlink points back into the aforementioned
- /sys/devices/socX devices.
