The J784S4 SoC belongs to the K3 Multicore SoC architecture platform, providing advanced system integration in automotive, ADAS and industrial applications requiring AI at the network edge. This SoC extends the K3 Jacinto 7 family of SoCs with focus on raising performance and integration while providing interfaces, memory architecture and compute performance for multi-sensor, high concurrency applications. Some highlights of this SoC are: * Up to 8 Cortex-A72s, four clusters of lockstep capable dual Cortex-R5F MCUs, 4 C7x floating point vector DSPs with Matrix Multiply Accelerator(MMA) for deep learning and CNN. * 3D GPU: Automotive grade IMG BXS-4-64 * Vision Processing Accelerator (VPAC) with image signal processor and Depth and Motion Processing Accelerator (DMPAC) * Three CSI2.0 4L RX plus two CSI2.0 4L TX, two DSI Tx, one eDP/DP and one DPI interface. * Integrated gigabit ethernet switch, up to 8 ports (TDA4VH), two ports support 10Gb USXGMII; Two 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role device subsystems, Up to 20 MCANs, among other peripherals. See J784S4 Technical Reference Manual (SPRUJ52 - JUNE 2022) for further details: http://www.ti.com/lit/zip/spruj52 bootlog: https://pastebin.ubuntu.com/p/XzbP9mHkKF/plain/ Changelog: - Disabled all the IPs that are not mandatory for booting up the SoC by default in the dtsi, and thus this gives a minimal SoC boot devicetree. - Moved no-1-8-v property from the k3-j784s4-evm.dts file to k3-j784s4-main.dtsi file. - Naming changes (hwlock, regulator) and commit description changes. - Added device specific compatible for j721e system controller. - Dropped bootargs completely.
