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
|

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

Provides IIO core support for triggers. Currently these

are used to initialize capture of samples to push into

ring buffers. The triggers are effectively a 'capture

This value controls the maximum number of consumers that a

given trigger may handle. Default is 2.
