* 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

|
|
* 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.
