Dst,stm32-adfsdm.txt1 STMicroelectronics Audio Digital Filter Sigma Delta modulators(DFSDM)
3 The DFSDM allows PDM microphones capture through SPI interface. The Audio
4 interface is seems as a sub block of the DFSDM device.
5 For details on DFSDM bindings refer to ../iio/adc/st,stm32-dfsdm-adc.txt
8 - compatible: "st,stm32h7-dfsdm-dai".
10 - #sound-dai-cells : Must be equal to 0
12 - io-channels : phandle to iio dfsdm instance node.
14 Example of a sound card using audio DFSDM node.
17 compatible = "audio-graph-card";
