+ 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.

+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.
