Please use subject prefixes matching the subsystem. You can get them for example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory your patch is touching. It is dt-bindings, not something else. A nit, subject: drop second/last, redundant "bindings for". The "dt-bindings" prefix is already stating that these are bindings.

You are right that there is the ordering number MBa9352LA-AA, so the compatible would be "tq,imx93-tqma9352-mba9352la". But the actual values for the wildcards is copied from the soldered module. So using a TQMa9351LA would result in MBa9351LA-AA, although the mainboard is identical. Best regards, Alexander > Best regards, > Krzysztof
