Hello,
Here is a new version integrating last comments
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.
Regards, Arnaud
