Hello, > Use standard property units "-ms". I made it in exactly the same way as it is done for the "ti,micbias:". - ti,micbias: Intended MICBIAS voltage (datasheet section 9.6.7). Select 0/1/2/3/4/5/6/7 to specify MICBIAS voltage 2.1V/2.2V/2.3V/2.4V/2.5V/2.6V/2.7V/2.8V Default value is "1" (2.2V). ?> Anyway new properties cannot be accepted.

Thanks, I am not really sure how yaml works. But I can have a look. Astrid
