[ Upstream commit2e4e0984c7] For a 900MHz i.MX6ULL CPU the 792MHz OPP is disabled. There is no convincing reason to disable this OPP. If a CPU can run at 900MHz, it should also be able to cope with 792MHz. Looking at the voltage level of 792MHz in [1] (page 24, table 10. "Operating Ranges") the current defined OPP is above the minimum. So the voltage level shouldn't be a problem. However in [2] (page 24, table 10. "Operating Ranges"), it is not mentioned that 792MHz OPP isn't allowed. Change it to only disable 792MHz OPP for i.MX6ULL types below 792 MHz.

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.
