The J784S4 SoCs have four TMS320C71x DSP subsystems in the MAIN voltage domain. The functionality of these DSP subsystems is similar to the C71x DSP subsystems on earlier k3 device J721S2. Each subsystem has a 48 KB of L1D configurable SRAM/Cache and 512 KB of L2 SRAM/Cache. This subsystem has a CMMU but is not currently used. The inter-processor communication between the main A72 cores and the C71x DSPs is achieved through shared memory and mailboxes. Add the DT nodes for these DSP processor sub-systems.

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.
