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.
