This driver works by adjusting the divider on the DRAM controller's module clock. Thus there is no fixed set of OPPs, only "full speed" down to "quarter speed" (or whatever the maximum divider is on that variant). It makes use of the MDFS hardware in the MBUS, in "DFS" mode, which takes care of updating registers during the critical section while DRAM is inaccessible. This driver should support several sunxi SoCs, starting with the A33, which have a DesignWare DDR3 controller with merged PHY register space and the matching MBUS register layout (so not A63 or later). However, the driver has only been tested on the A64/H5, so those are the only compatibles enabled for now.

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.
