+ * 1. If a device mixes different microphones types with different polarity
+ * and/or the absolute polarity matters the PCM signal from a microphone
+ * can be inverted with the controls.
+ *
+ * 2. If the microphones in a stereo pair do not appear in captured stream
+ * in desired order due to board schematics choises they can be swapped with
+ * the clk_edge parameter.
+ *
+ * 3. If PDM bit errors are seen in capture (poor quality) the skew parameter
+ * that delays the sampling time of data by half cycles of DMIC source clock
+ * can be tried for improvement. However there is no guarantee for this to fix
+ * data integrity problems.

+ * initial value 1 if updates done for the to driver would alter the operation
+ * of the microphone.
+ *
+ * Note: The microphone clock (pdmclk_min, pdmclk_max, duty_min, duty_max)
+ * parameters need to be set as defined in microphone data sheet. 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. In such case set the clock range limits of the desired mode to
+ * avoid the driver to set clock to an illegal rate.
+ *
+ * The duty cycle could be set to 48-52% if not known. Generally these
+ * parameters can be altered within data sheet specified limits to match
+ * required audio application performance power.
+ *
+ * The microphone clock needs to be usually about 50-80 times the used audio
+ * sample rate. 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). Exceed of 100 ms will be
+ * treated as an error.
