Merge series "dt-bindings: stm32: convert audio dfsdm to json-schema" from Olivier Moysan <olivier.moysan@st.com>:

Browse Source 
Some audio properties documented in st,stm32-adfsdm.txt are already documented
in Documentation/devicetree/bindings/iio/adc/st,stm32-dfsdm-adc.yaml bindings.
Move remaining properties from st,stm32-adfsdm.txt to st,stm32-dfsdm-adc.yaml,
and remove st,stm32-adfsdm.txt.

Changes in v2:
- Complete st,stm32-dfsdm-adc.yaml rather than converting st,stm32-adfsdm.txt

Olivier Moysan (2):
  dt-bindings: stm32: dfsdm: update audio properties
  dt-bindings: stm32: dfsdm: remove stm32-adfsdm.txt binding

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.
