+What: /sys/bus/iio/devices/triggerX/trigger_polarity
+KernelVersion: 4.11

+Description:
+ The STM32 ADC can be configured to use external trigger sources
+ (e.g. timers, pwm or exti gpio). Then, it can be tuned to start
+ conversions on external trigger by either:
+
+ - "rising-edge"
+ - "falling-edge"
+ - "both-edges".
+
+ Reading returns current trigger polarity.
+
+ Writing value before enabling conversions sets trigger polarity.
