[PATCH v8 00/13] Add STM32 DFSDM support

[Arnaud Pouliquen]

Hello

New version based on minor comments from Jonathan.

Main deltas V8 vs V7:
- Few typos fixes.
- Function return optimizations in sound/soc/stm/stm32_adfsdm.c.

Main deltas V7 vs V6:
- Replaces the custom license information text with the appropriate 
  SPDX identifier.
- Few fixes in sound/soc/stm/stm32_adfsdm.c and stm32-dfsdm-core.c.
- Add missing #interrupt-cells in binding examples.
- Integrate last Jonathan's comments.

Main deltas V6 vs V5:
- Fix warning reported by kbuild test in :
   include/linux/iio/consumer.h
   sound/soc/stm/stm32_adfsdm.c

Main deltas V5 vs V4:
- Integrate ASOC DAI as a subnode of the DFSDM.
- Add in kernel consumer interface to allow to manipulate attribute.

Thanks,
Arnaud
