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).

41 are used to initialize capture of samples to push into
42 buffers. The triggers are effectively a 'capture

78 Framework to handle complex IIO aggregate devices. The typical
79 architecture that can make use of this framework is to have one
80 device as the frontend device which can be "linked" against one or
81 multiple backend devices. The framework then makes it easy to get
82 and control such backend devices.
