  12         help
  13           Provides a frequency based IIO trigger using high resolution
  14           timers as interrupt source.

  20         tristate "Generic interrupt trigger"
  21         help
  22           Provides support for using an interrupt of any type as an IIO
  23           trigger.  This may be provided by a gpio driver for example.

  32           Select this option to enable STM32 Low-Power Timer Trigger.
  33           This can be used as trigger source for STM32 internal ADC
  34           and/or DAC.

  51         help
  52           An experimental trigger, used to allow sensors to be sampled as fast
  53           as possible under the limitations of whatever else is going on.
  54           Uses a tight loop in a kthread.  Will only work with lower half only
  55           trigger consumers.

  57           To compile this driver as a module, choose M here: the
  58           module will be called iio-trig-loop.

  64         help
  65           Provides support for using SYSFS entries as IIO triggers.
  66           If unsure, say N (but it's safe to say "Y").
  67
  68           To compile this driver as a module, choose M here: the
