So, you should be able to add a lot of devices (aka users) instead of making this a barebones dts as the first introduction - I see no benefit of things coming in piece meal - other than creating all kind of dependency mayhem that I don't want to deal with. Please make sure that all nodes for all peripherals that can be introduced in v5.11-rc1 is part of this introduction of device.

The AM642 SoC belongs to the K3 Multicore SoC architecture platform, providing advanced system integration to enable applications such as Motor Drives, PLC, Remote IO and IoT Gateways. Some highlights of this SoC are: * Dual Cortex-A53s in a single cluster, two clusters of dual Cortex-R5F MCUs, and a single Cortex-M4F. * Two Gigabit Industrial Communication Subsystems (ICSSG). * Integrated Ethernet switch supporting up to a total of two external ports. * PCIe-GEN2x1L, USB3/USB2, 2xCAN-FD, eMMC and SD, UFS, OSPI memory controller, QSPI, I2C, eCAP/eQEP, ePWM, ADC, among other peripherals. * Centralized System Controller for Security, Power, and Resource Management (DMSC). See AM64X Technical Reference Manual (SPRUIM2, Nov 2020) for further details: https://www.ti.com/lit/pdf/spruim2 Introduce basic support for the AM642 SoC to enable minimal ramdisk boot. Introduce a limited set of MAIN domain periperhals under cbass_main and a placeholder cbass_mcu node for future MCU domain usage.
