0009 config IIO_HRTIMER_TRIGGER
0010 tristate "High resolution timer trigger"
0011 depends on IIO_SW_TRIGGER
0012 help
0013 Provides a frequency based IIO trigger using high resolution
0014 timers as interrupt source.

0016 To compile this driver as a module, choose M here: the
0017 module will be called iio-trig-hrtimer.
0018
0019 config IIO_INTERRUPT_TRIGGER
0020 tristate "Generic interrupt trigger"
0021 help
0022 Provides support for using an interrupt of any type as an IIO
0023 trigger. This may be provided by a gpio driver for example.
0024
0025 To compile this driver as a module, choose M here: the
0026 module will be called iio-trig-interrupt.

0030 depends on MFD_STM32_LPTIMER || COMPILE_TEST
0031 help
0032 Select this option to enable STM32 Low-Power Timer Trigger.
0033 This can be used as trigger source for STM32 internal ADC
0034 and/or DAC.

0036 To compile this driver as a module, choose M here: the
0037 module will be called stm32-lptimer-trigger.

0048 config IIO_TIGHTLOOP_TRIGGER
0049 tristate "A kthread based hammering loop trigger"
0050 depends on IIO_SW_TRIGGER
0051 help
0052 An experimental trigger, used to allow sensors to be sampled as fast
0053 as possible under the limitations of whatever else is going on.
0054 Uses a tight loop in a kthread. Will only work with lower half only
0055 trigger consumers.

0061 tristate "SYSFS trigger"
0062 depends on SYSFS
0063 select IRQ_WORK
0064 help
0065 Provides support for using SYSFS entries as IIO triggers.
0066 If unsure, say N (but it's safe to say "Y").
0067
0068 To compile this driver as a module, choose M here: the
0069 module will be called iio-trig-sysfs.
