Hello Everyone!
This series will introduce basic support (SD and UART) support for Texas Instruments J784S4 EVM.
The J784S4 SoC device tree patches are taken from kernel patch submissions and will be updated as they are accepted and merged to the kernel tree. All other patches are specific to SPL and u-boot and do not have dependency on other trees. Appreciate a review for acceptance to u-boot tree.
Here are some of the salient features of the J784S4 automotive grade application processor:
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 MC1 * 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
In addtion, the J784S4 EVM board is designed for TI J784S4 SoC. It supports the following interfaces: * 32 GB DDR4 RAM * x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode * x1 Input Audio Jack, x1 Output Audio Jack * x1 USB2.0 Hub with two Type A host and x1 USB 3.1 Type-C Port * x2 4L PCIe connector * x1 UHS-1 capable micro-SD card slot * 512 Mbit OSPI flash, 1 Gbit Octal NAND flash, 512 Mbit QSPI flash, UFS flash. * x6 UART through UART-USB bridge * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs * 40-pin User Expansion Connector * x2 ENET Expansion Connector, x1 GESI expander, x2 Display connector * x1 15-pin CSI header * x6 MCAN instances
