Subject: [PATCH 2/3] arm64: dts: ti: Introduce J722S family of SoCs
Date:   Wed, 13 Dec 2023 18:19:29 +0530
Message-ID: <20231213124930.3012-3-vaishnav.a@ti.com>

The J722S is a family of  application processors built for Automotive and
Linux Application development. Scalable Arm Cortex-A53 performance and
embedded features, such as multi high-definition display support,
3D-graphics acceleration, 4K video acceleration, and extensive peripherals
make the J722S well-suited for a broad range of automation and industrial
application, including automotive digital instrumentation, automotive
displays, industrial HMI, and more.

Some highlights of J722S SoC are:
    * Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster.
    * One Device manager Cortext-R5F for system power and resource
      management, two Cortex-R5F for Functional Safety or
      general-purpose usage and two C7x floating point vector DSPs
      with Matrix Multiply Accelerator(MMA) for deep learning.
    * One 3D GPU up to 50 GLFOPS
    * H.264/H.265, JPEG Video Encode/Decode.
    * Display support: 3x display support over OLDI/LVDS (1x OLDI-DL, 1x or
      2x OLDI-SL), DSI, or DPI. Up to 3840x1080@60fps resolution
    * Integrated Giga-bit Ethernet switch supporting up to a total of two
      external ports (TSN capable).
    * Vision Processing Accelerator (VPAC) with image signal processor
      and Depth and Motion Processing Accelerator (DMPAC).
    * 7xUARTs, 3xSPI, 5xI2C, 2xUSB2, 2xCAN-FD, 3xMMC and SD, GPMC for
      NAND/FPGA connection, OSPI memory controller, 5xMcASP for audio,
      4xCSI-RX for Camera, 1 PCIe Gen3 controller, eCAP/eQEP,
      ePWM, among other peripherals.
    * Dedicated Centralized Hardware Security Module with support for
      secure boot, debug security and crypto acceleration and trusted
      execution environment.
    * One 32-bit DDR Subsystem that supports LPDDR4 memory type.

J722S family of SoCs is a superset of the AM62P SoC family and shares
similar memory map, thus the nodes are being reused from AM62P includes
instead of duplicating the definitions. Unused nodes with dependencies
are kept disabled and will be enabled later when the dependencies are
enabled.

For those interested, more details about this SoC can be found in the
Technical Reference Manual here:

checkpatch error is ignored for arch/arm64/boot/dts/ti/k3-pinctrl.h:
ERROR: Macros with complex values should be enclosed in parentheses

However, we do not need parentheses enclosing the values for this
macro as we do intend it to generate two separate values as has been
done for other similar platforms.
