158	  typically only enabled for developers for debug purposes, before
159	  codec/machine driver is ready, or to exclude the impact of those

185	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.

195	  This option enables caching of debugfs
196	  memory -> DSP resource (memory, register, etc)
197	  before the audio DSP is suspended. This will increase the suspend
198	  latency and therefore should be used for debug purposes only.
