    help

      The industrial I/O subsystem provides a unified framework for

      drivers for many different types of embedded sensors using a

      number of different physical interfaces (i2c, spi, etc).

    help

      Provide core support for various buffer based data

      acquisition methods.

    select CONFIGFS_FS

    help

      This allows configuring various IIO bits through configfs

      (e.g. software triggers). For more info see

      Documentation/iio/iio_configfs.txt.

config IIO_TRIGGER

    bool "Enable triggered sampling support"

    help

      Provides IIO core support for triggers.  Currently these

      are used to initialize capture of samples to push into

      buffers.  The triggers are effectively a 'capture

      data now' interrupt.

config IIO_CONSUMERS_PER_TRIGGER

       int "Maximum number of consumers per trigger"

       depends on IIO_TRIGGER

       default "2"

       help

    This value controls the maximum number of consumers that a

    given trigger may handle. Default is 2.

config IIO_SW_DEVICE

    tristate "Enable software IIO device support"

    select IIO_CONFIGFS

    help

     Provides IIO core support for software devices. A software

     device can be created via configfs or directly by a driver

     using the API provided.

config IIO_SW_TRIGGER

    tristate "Enable software triggers support"

    select IIO_CONFIGFS

    help

     Provides IIO core support for software triggers. A software

     trigger can be created via configfs or directly by a driver

     using the API provided.
