TI=E2=80=99s AM68 SoC comprises of dual core A72= , high performance vision accelerators, hardware accelerators, latest C71x DSP, high bandwidth real-time IPs for capture and display. The SoC is power optimized to provide best in class performance for industrial applications. AM68 SK supports the following interfaces: * 16 GB LPDDR4 RAM * x1 Gigabit Ethernet interface * x1 USB 3.1 Type-C port * x2 USB 3.1 Type-A ports * x1 PCIe M.2 M Key * 512 Mbit OSPI flash * x2 CSI2 Camera interface (RPi and TI Camera connector) * 40-pin Raspberry Pi GPIO header SK's System on Module (SoM) contains the SoC and DDR. Therefore, add DT node for the SOC and DDR on the SoM.
