Hi, I send this as an RFC, as I'm digging to try to get as generic as possible GPIO based trigger support, as discussed earlier in other patchset "Add EXTI GPIO trigger support to STM32 ADC": https://www.spinics.net/lists/arm-kernel/msg559091.html
Following various comments on this, I sent this RFC to address two topics, that I see as possible prerequisite: - Add trigger OF support - GPIO based trigger Please feel free to advise. Best Regards.
