0008 help
0009 The industrial I/O subsystem provides a unified framework for
0010 drivers for many different types of embedded sensors using a
0011 number of different physical interfaces (i2c, spi, etc).

0029 This allows configuring various IIO bits through configfs
0030 (e.g. software triggers). For more info see
0031 Documentation/iio/iio_configfs.rst.

0035 help
0036 Provides IIO core support for triggers. Currently these
0037 are used to initialize capture of samples to push into
0038 buffers. The triggers are effectively a 'capture
0039 data now' interrupt.

0046 This value controls the maximum number of consumers that a
0047 given trigger may handle. Default is 2.
