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: https://www.ti.com/lit/zip/sprujb3 Co-developed-by: Jayesh Choudhary <j-choudhary@ti.com> Signed-off-by: Jayesh Choudhary <j-choudhary@ti.com> Signed-off-by: Vaishnav Achath <vaishnav.a@ti.com> --- 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.

None of the devices have been as close a reuse device as this has been. errata in one carries over to the other etc.. There are definitely some differences - for example: itap/otap delays for mmc those would be unique on this device, but overrides with documentation will make perfect sense there.

Please check with your hardware teams if the am62p SoC level thermal behavior will be similar to j722s or will it be different.

I had previously suggested to do that SoC level (which means at am62p dtsi) since the remoteprocs have direct dependency on how the memory layouts are partitioned in board.dts - but i had asked folks working on remote procs to do that consistently across SoCs.

I'd argue J721e and J7200 are more similar in terms of reuse. It was a mistake to model them as simple super/subsets of each other, only causes confusion later.
