Extend the AD4000 series device tree documentation to also describe PulSAR devices. The single-channel series of PulSAR devices is similar to the AD4000 series except PulSAR devices sample at slower rates and don't have a configuration register. Because PulSAR devices don't have a configuration register, they don't support all features of AD4000 devices and thus fewer interfaces are provided to user space. Also, while AD4000 may have their SDI pin connected to SPI host MOSI line, PulSAR SDI pin is never connected to MOSI. Some devices within the PulSAR series are just faster versions of others. >From fastest to slowest, AD7980, AD7988-5, AD7686, AD7685, and AD7988-1 are all 16-bit pseudo-differential pin-for-pin compatible ADCs. Devices that only vary on the sample rate are documented with a common fallback compatible.

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 reStructuredText 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.
