| * and/or the absolute polarity matters the PCM signal from a microphone |

| * |
| * 2. If the microphones in a stereo pair do not appear in captured stream |

| * 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 |

| /* This struct contains the global settings for all 2ch PDM controllers. The |

| * initial value 1 if updates done for the to driver would alter the operation |
| * of the microhone. |
| * |
| * 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. |
