 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()
