When a software reset is performed on the AD2S1210 to make the selected excitation frequency take effect, it always triggers faults on the input signals because the output signal is interrupted momentarily. So we need to clear the faults after the software reset to avoid triggering fault events the next time a sample is read. The datasheet specifies a time t[track] in Table 27 that specifies the settle time in milliseconds after a reset depending on the selected resolution. This is used in the driver to add an appropriate delay.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
