config IIO_HRTIMER_TRIGGER
tristate "High resolution timer trigger"
depends on IIO_SW_TRIGGER
help
Provides a frequency based IIO trigger using high resolution
timers as interrupt source.
To compile this driver as a module, choose M here: the
module will be called iio-trig-hrtimer.
config IIO_INTERRUPT_TRIGGER
tristate "Generic interrupt trigger"
help
Provides support for using an interrupt of any type as an IIO
trigger. This may be provided by a gpio driver for example.
To compile this driver as a module, choose M here: the
module will be called iio-trig-interrupt.
config IIO_STM32_LPTIMER_TRIGGER
tristate "STM32 Low-Power Timer Trigger"
depends on MFD_STM32_LPTIMER || COMPILE_TEST
help
Select this option to enable STM32 Low-Power Timer Trigger.
This can be used as trigger source for STM32 internal ADC
and/or DAC.
To compile this driver as a module, choose M here: the
module will be called stm32-lptimer-trigger.
config IIO_STM32_TIMER_TRIGGER
tristate "STM32 Timer Trigger"
depends on (ARCH_STM32 && OF && MFD_STM32_TIMERS) || COMPILE_TEST
help
Select this option to enable STM32 Timer Trigger
To compile this driver as a module, choose M here: the
module will be called stm32-timer-trigger.
config IIO_TIGHTLOOP_TRIGGER
tristate "A kthread based hammering loop trigger"
depends on IIO_SW_TRIGGER
help
An experimental trigger, used to allow sensors to be sampled as fast
as possible under the limitations of whatever else is going on.
Uses a tight loop in a kthread. Will only work with lower half only
trigger consumers.
To compile this driver as a module, choose M here: the
module will be called iio-trig-loop.
config IIO_SYSFS_TRIGGER
tristate "SYSFS trigger"
depends on SYSFS
select IRQ_WORK
help
Provides support for using SYSFS entries as IIO triggers.
If unsure, say N (but it's safe to say "Y").
To compile this driver as a module, choose M here: the
module will be called iio-trig-sysfs.
