Daniel Baluta ac5006a2a5 iio: trigger: Introduce IIO hrtimer based trigger
This patch registers a new IIO software trigger interrupt source
based on high resolution timers.

Notice that if configfs is enabled we create sampling_frequency
attribute allowing users to change hrtimer period (1/sampling_frequency).

The IIO hrtimer trigger has a long history, this patch is based on
an older version from Marten and Lars-Peter.

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_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.
