 121  * that delays the sampling time of data by half cycles of DMIC source clock
 122  * can be tried for improvement. However there is no guarantee for this to fix

 144  * initial value 1 if updates done for the to driver would alter the operation
 145  * of the microphone.
 146  *
 147  * Note: The microphone clock (pdmclk_min, pdmclk_max, duty_min, duty_max)
 148  * parameters need to be set as defined in microphone data sheet. E.g. clock
 149  * range 1.0 - 3.2 MHz is usually supported microphones. Some microphones are
 150  * multi-mode capable and there may be denied mic clock frequencies between
 151  * the modes. In such case set the clock range limits of the desired mode to
 152  * avoid the driver to set clock to an illegal rate.
 153  *
 154  * The duty cycle could be set to 48-52% if not known. Generally these
 155  * parameters can be altered within data sheet specified limits to match
 156  * required audio application performance power.
 157  *
 158  * The microphone clock needs to be usually about 50-80 times the used audio
 159  * sample rate. With highest sample rates above 48 kHz this can relaxed
 160  * somewhat.
 161  *
 162  * The parameter wake_up_time describes how long time the microphone needs
 163  * for the data line to produce valid output from mic clock start. The driver
 164  * will mute the captured audio for the given time. The min_clock_on_time
 165  * parameter is used to prevent too short clock bursts to happen. The driver
 166  * will keep the clock active after capture stop if this time is not yet
 167  * met. The unit for both is microseconds (us). Exceed of 100 ms will be
 168  * treated as an error.
