Expose the NMI safe accessor to the monotonic raw clock to the
tracer. The mono clock was added with commit
1b3e5c0936046e7e023149ddc8946d21c2ea20eb. The advantage of the

This patch registers a new IIO software trigger interrupt source

A software trigger associates an IIO device trigger with a software
