Add IPMMU device nodes for the R-Car M3-N (r8a77965), V3H (r8a77980) and E3 (r8a77990) SoCs. * The r8a77965 IPMMU is quite similar to r8a7796 however VP0 has been added and PV1 has been removed. Also the IMSSTR bit assignment has been reworked. * The r8a77980 IPMMU is quite similar to r8a77970 however VC0 has been added. The IMSSTR bit assignment has also been reworked. Power domains are also quite different however the the documentation is rather unclear about this topic. Until we know better VC0 gets assigned to R8A77980_PD_ALWAYS_ON. * The r8a77990 IPMMU is similar to r8a77995. Power domains are however different and the public documentation is still unclear. Based on preliminary information from the hardware team the R-Car E3 SoC comes with an IPMMU-VP0 device in an Always-on power domain and the IPMMU-VC0 is placed as expected in the A3VC power domain.

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.
