Hello Benjamin, Hello Fabrice, In the stm32-timer-cnt driver I find unused #defines for TIM_CCMR_MASK and TIM_CCER_MASK, which to me hint that support for the "input capture mode"[1] was implemented but removed prior to upstreaming. It doesn't look like the counter device API is yet made to support such an input capture mode (latching a counter value on an external event, e.g. to timestamp incoming rising edges to measure jitter between pulses). I am still very new to this, so I figured I ask whether you already have thoughts (or maybe code to share) on how to best integrate this with the counter device API. I've added linux-iio/linux-stm32 to the CC as well, so if someone else has an idea how to best do this, please share.
