arm64: dts: ti: Add support for J784S4 EVM board
Browse files Browse the repository at this point in the history 
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

Add basic support for J784S4-EVM.
