Hi, Sorry, I have some trouble understanding the specifics of this. Is EXTI a hardware input signal into the ADC that automatically triggers a conversion when asserted? If yes how is it configured which external signal is used here. Your bindings suggest that any GPIO can be used, but the driver only differentiates between EXTI on or EXTI off. Or is this just a software triggered conversion? The GPIO triggers a software interrupt routine and the interrupt routine than triggers conversion? -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
