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