The Toradex LAVA HAT is a board used for automated hardware-in-the-loop (HIL) testing, it provides several test-related functionalities, and exists in multiple variants depending on the board it is mated with. The SPI function is implemented with a loopback on the MISO/MOSI signals. As the device can be fully described using only "compatible" and "reg", it is appropriate to list it under trivial-devices.yaml rather than introducing a dedicated binding. The SPI implementation is identical across all Toradex LAVA HAT variants, so a single compatible string is sufficient.
