The MediaTek MT8196 SoC has new cpufreq hardware, with added memory register ranges to control Dynamic-Voltage-Frequency-Scaling. The DVFS hardware is controlled through a set of registers referred to as "FDVFS". They set the target frequency the DVFS hardware should aim for for each performance domain. Instead of working around the old binding and its already established meanings for the reg items, add a new binding. The FDVFS register memory region is at the beginning, which allows us to easily expand this binding for future SoCs which may have more than 3 performance domains.

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.
