    iio: core: Introduce IIO software triggers · b662f809
    Daniel Baluta authored
    A software trigger associates an IIO device trigger with a software
    interrupt source (e.g: timer, sysfs). This patch adds the generic
    infrastructure for handling software triggers.
    
    Software interrupts sources are kept in a iio_trigger_types_list and
    registered separately when the associated kernel module is loaded.
    
    Software triggers can be created directly from drivers or from user
    space via configfs interface.
    
    To sum up, this dynamically creates "triggers" group to be found under
    /config/iio/triggers and offers the possibility of dynamically
    creating trigger types groups. The first supported trigger type is
    "hrtimer" found under /config/iio/triggers/hrtimer.
