E.g. clock * range 1.0 - 3.2 MHz is usually supported microphones. Some microphones are * multi-mode capable and there may be denied mic clock frequencies between * the modes.

With highest sample rates above 48 kHz this can relaxed * somewhat. * * The parameter wake_up_time describes how long time the microphone needs * for the data line to produce valid output from mic clock start. The driver * will mute the captured audio for the given time. The min_clock_on_time * parameter is used to prevent too short clock bursts to happen. The driver * will keep the clock active after capture stop if this time is not yet * met. The unit for both is microseconds (us).
