The sama7g5 version of the XDMAC supports priority configuration and outstanding capabilities. Add defines for the specific registers for this configuration, together with recommended settings. However the settings are very different if the XDMAC is a mem2mem or a per2mem controller. Thus, we need to differentiate according to device tree property.

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.
