+contact: Lee Jones <lee.jones at linaro.org>
+Description:
+ The /sys/devices/soc 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.
+ This directory contains two kinds of attributes:
+ - Common attributes:
+ * machine: SoC machine name (e.g. Ux500).
+ * family: SoC family name (e.g. DB8500).
+ - SoC-specific attributes:
+ * SoC vendor declared
+ * ST-Ericsson delcare the following
+ * soc_id: SoC serial number
+ * revision: SoC revision number
+ * process: the way in which the chip was manufactured
+Users:
+ Any platform dependent user-space applications or profiling tools.
