The SoC core voltage can't be changed without taking into account the clock rate of External Memory Controller. Document OPP table that will be used for dynamic voltage frequency scaling, taking into account EMC voltage requirement. Document optional core voltage regulator, which is optional because some boards may have a fixed core regulator and still frequency scaling may be desired to have.

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.
