The K3 AM65x and J721E SoCs have the next generation of the PRU-ICSS IP, commonly called ICSSG. The PRUSS INTC present within the ICSSG supports more System Events (160 vs 64), more Interrupt Channels and Host Interrupts (20 vs 10) compared to the previous generation PRUSS INTC instances. The first 2 and the last 10 of these host interrupt lines are used by the PRU and other auxiliary cores and sub-modules within the ICSSG, with 8 host interrupts connected to MPU. The host interrupts 5, 6, 7 are also connected to the other ICSSG instances within the SoC and can be partitioned as per system integration through the board dts files. Enhance the PRUSS INTC driver to add support for this ICSSG INTC instance.

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.
