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. For bindings, the preferred subjects are explained here: https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html#i-for-patch-submitters Subject/commit msg: drop MFD and explain what the hardware is.

Drop description, > + maxItems: 1 I don't think this was tested at all. It is heavily incomplete, considering this is sort of MFD device. Or you split patches in odd way.
