arch: arm64: dts: Add support for AM69 Starter Kit
AM69 Starter Kit is a single board designed for TI AM69 SOC that
provides advanced system integration in automotive ADAS applications,
autonomous mobile robot and edge AI applications. The SOC comprises
of Cortex-A72s in dual clusters, lockstep capable dual Cortex-R5F MCUs,
Vision Processing Accelerators (VPAC) with Image Signal Processor (ISP)
and multiple vision assist accelerators, Depth and Motion Processing
Accelerators (DMPAC), Deep-learning Matrix Multiply Accelerator(MMA)
and C7x floating point vector DSP
AM69 SK supports the following interfaces:
* 32 GB LPDDR4 RAM
* x1 Gigabit Ethernet interface
* x3 USB 3.0 Type-A ports
* x1 USB 3.0 Type-C port
* x1 UHS-1 capable micro-SD card slot
* x4 MCAN instances
* 32 GB eMMC Flash
* 512 Mbit OSPI flash
* x2 Display connectors
* x1 PCIe M.2 M Key
* x1 PCIe M.2 E Key
* x1 4L PCIe Card Slot
* x3 CSI2 Camera interface
* 40-pin Raspberry Pi header
Add initial support for the AM69 SK board.
