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.

As the removed comments say, these aren't DT based devices. of_dma_configure() is going to stop allowing a NULL DT node and calling it will no longer work. The comment is also now out of date as of commit 9ab91e7c ("arm64: default to the direct mapping in get_arch_dma_ops"). Direct mapping is now the default rather than dma_dummy_ops. According to Stefano and Oleksandr, the only other part needed is setting the DMA masks and there's no reason to restrict the masks to 32-bits. So set the masks to 64 bits.
