   9          The industrial I/O subsystem provides a unified framework for
  10          drivers for many different types of embedded sensors using a
  11          number of different physical interfaces (i2c, spi, etc).

  18          Provide core support for various buffer based data
  19          acquisition methods.

  26          Should be selected by any drivers that do-inkernel push
  27          usage.  That is, those where the data is pushed to the consumer.

  32        help
  33          A simple fifo based on kfifo.  Use this if you want a fifo
  34          rather than a ring buffer. Note that this currently provides
  35          no buffer events so it is up to userspace to work out how
  36          often to read from the buffer.

  50          Provides IIO core support for triggers.  Currently these
  51          are used to initialize capture of samples to push into
  52          ring buffers.  The triggers are effectively a 'capture
  53          data now' interrupt.

  60        This value controls the maximum number of consumers that a
  61        given trigger may handle. Default is 2.
