Why?

What you are doing we see easily from the diff. I do not see why. Your
commit msg must explain this.

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

Missing serial prefix and final is fsl,s32-linflexuart, not linflexuart

Nope, drop the example. Not explained why you need it and really no point.
