arm: dts: Add k3-j721e-beagleboneai64
BeagleBoard.org BeagleBone AI-64 is an open source hardware single
board computer based on the Texas Instruments TDA4VM SoC featuring
dual-core 2.0GHz Arm Cortex-A72 processor, C7x+MMA and 2 C66x
floating-point VLIW DSPs, 3x dual ARM Cortex-R5 co-processors,
2x 6-core Programmable Real-Time Unit and Industrial Communication
SubSystem, PowerVR Rogue 8XE GE8430 3D GPU. The board features 4GB
DDR4, USB3.0 Type-C, 2x USB SS Type-A, miniDisplayPort, 2x 4-lane
CSI, DSI, 16GB eMMC flash, 1G Ethernet, M.2 E-key for WiFi/BT, and
BeagleBone expansion headers.
This board family can be indentified by the BBONEAI-64-B0 in the
at24 eeprom:
