+PM Quality Of Service Interface.
This interface provides a kernel and user mode interface for registering
performance expectations by drivers, subsystems and user space applications on
Currently we have {cpu_dma_latency, network_latency, network_throughput} as the
initial set of pm_qos parameters.
+Each parameters have defined units:
+ * latency: usec
+ * timeout: usec
+ * throughput: kbs (kilo bit / sec)
+
The infrastructure exposes multiple misc device nodes one per implemented
parameter. The set of parameters implement is defined by pm_qos_power_init()
and pm_qos_params.h. This is done because having the available parameters
