[ Upstream commit36eb7dc1bd] imx6ul_opp_check_speed_grading is called for both i.MX6UL and i.MX6ULL. Since the i.MX6ULL was introduced to a separate ocotp compatible node later, it is possible that the i.MX6ULL has also dtbs with "fsl,imx6ull-ocotp". On a system without nvmem-cell speed grade a missing check on this node causes a driver fail without considering the cpu speed grade. This patch prevents unwanted cpu overclocking on i.MX6ULL with compatible node "fsl,imx6ull-ocotp" in old dtbs without nvmem-cell speed grade.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
