The DMA (BCDMA/PKTDMA and their rings/flows) events are under the INTA's supervision as unmapped events in AM64. In order to keep the current SW stack working, the INTA driver must replace the dev_id with it's own when a request comes for BCDMA or PKTDMA resources. Implement parsing of the optional "ti,unmapped-event-sources" phandle array to get the sci-dev-ids of the devices where the unmapped events originate.

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.
