-Platforms based on Texas Instruments K3 Multicore SoC architecture
-shall follow the following scheme:
-
-SoCs

-
-Each device tree root node must specify which exact SoC in K3 Multicore SoC
-architecture it uses, using one of the following compatible values:
-
-- AM654
-  compatible = "ti,am654";
-
-- J721E
-  compatible = "ti,j721e";
-
-Boards

-In addition, each device tree root node must specify which one or more
-of the following board-specific compatible values:
-
-- AM654 EVM
-  compatible = "ti,am654-evm", "ti,am654";
