ALH was inserted in the wrong place during integration, add after DMIC to mirror the file used by SOF firmware. No functional change, just text move in the same file to better track changes, if any.

|
|
* can be inverted with the controls.

|
|
* 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 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.
