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.

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_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.
