This makes sense as the STM32 DFSDM can use timer and/or lptimer. I think I'll post another patch later to remove the select in STM32_ADC config (no longer needed then... But it's not the subject here, right ?). - Two other patches to fix other warning/build issues I've seen while working on the stub option. See [2]: [1] https://lkml.org/lkml/2019/4/15/223 [2] https://lkml.org/lkml/2019/4/15/437 Sorry for the inconvenience, I should have seen this earlier.
