The xilinx-xadc IIO driver currently has support for the XADC in the Xilinx 7 series FPGAs. The system-monitor is the equivalent to the XADC in the Xilinx UltraScale and UltraScale+ FPGAs. The IP designers did a good job at maintaining backwards compatibility and only minor changes are required to add basic support for the system-monitor core. The non backwards compatible changes are: * Register map offset was moved from 0x200 to 0x400 * Only one ADC compared to two in the XADC * 10 bit ADC instead of 12 bit ADC * Two of the channels monitor different supplies Add the necessary logic to accommodate these changes to support the system-monitor in the XADC driver. Note that this patch does not include support for some new features found in the system-monitor like additional alarms, user supply monitoring and secondary system-monitor access. This might be added at a later time.

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.
