What: /sys/devices/.../power/pm_qos_latency_us
Date: March 2012
Contact: Rafael J. Wysocki <rjw@sisk.pl>
Description:
The /sys/devices/.../power/pm_qos_resume_latency_us attribute
contains the PM QoS resume latency limit for the given device,
which is the maximum allowed time it can take to resume the
device, after it has been suspended at run time, from a resume
request to the moment the device will be ready to process I/O,
in microseconds. If it is equal to 0, however, this means that
the PM QoS resume latency may be arbitrary.

Not all drivers support this attribute. If it isn't supported,
it is not present.

This attribute has no effect on system-wide suspend/resume and
hibernation.

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.

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.
