The ARM SMMU instantiations found on Tegra186 and later need inter- operation with the memory controller in order to correctly program stream ID overrides. Furthermore, on Tegra194 multiple instances of the SMMU can gang up to achieve higher throughput. In order to do this, they have to be programmed identically so that the memory controller can interleave memory accesses between them. Add the Tegra186 compatible string to make sure the interoperation with the memory controller can be enabled on that SoC generation.

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.
