The ADI PulSAR series of single-channel devices comprises differential and pseudo-differential ADCs that don't require any input data from the host controller. By not requiring a data input line, PulSAR devices can operate with a 3-wire only data bus in some setups. The AD4000 series and the single-channel PulSAR series of devices have similar SPI transfer specifications and wiring configurations. Single-channel PulSAR devices are slower than AD4000 and don't have a configuration register. That taken into account, single-channel PulSARs can be supported by the ad4000 driver without any increase in code complexity. Extend the AD4000 driver to also support single-channel PulSAR devices.

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.
