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

42 boolean "Enable triggered sampling support"
43 help
44 Provides IIO core support for triggers. Currently these
45 are used to initialize capture of samples to push into
46 ring buffers. The triggers are effectively a 'capture
47 data now' interrupt.
