Add support to request DRAM bandwidth (BW) with Memory Interconnect in Tegra234 SoC. The DRAM BW required for different modes depends on the link speed (Gen-1/2/3/4) and width/lanes (x1/x2/x4/x8). Currently, the DRAM frequency is always set to the maximum available but that results in the highest power consumption. The Memory Interconnect is a software feature which uses Interconnect framework (ICC). It adds the capability for Memory Controller (MC) clients to request bandwidth and therefore scale DRAM frequency dynamically depending on the required link speed so that the DRAM energy consumption can be optimized.

README
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.
