STMicroelectronics Audio Digital Filter Sigma Delta modulators(DFSDM)



The DFSDM allows PDM microphones capture through SPI interface. The Audio

interface is seems as a sub block of the DFSDM device.

For details on DFSDM bindings refer to ../iio/adc/st,stm32-dfsdm-adc.txt



Required properties:

  - compatible: "st,stm32h7-dfsdm-dai".



  - #sound-dai-cells : Must be equal to 0



  - io-channels : phandle to iio dfsdm instance node.



Example of a sound card using audio DFSDM node.
