   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).

  29           This allows configuring various IIO bits through configfs
  30           (e.g. software triggers). For more info see

  36           Provides IIO core support for triggers.  Currently these
  37           are used to initialize capture of samples to push into
  38           buffers.  The triggers are effectively a 'capture

  46         This value controls the maximum number of consumers that a
