When submitting patches, please use the format appropriate for the
subsystem.

  `git log --oneline -- <subsystem>` helps with this.

Also please provide a commit log containing a short description of the
change.  Are you enabling ARM64 becuase the driver is able to be used
on a new platform?  If not, how did this work before?  Etc.

I can add a short description. But there's really not much more to it
than the subject. We have ARM64 platforms we want to use this on. Some
are already released, and some are in development.

I also don't see what's wrong with the subject line...

I think at least a short description is always welcomed. Even if the
patch is obvious, it should state why the change was introduced.

Patch looks good to me, so after resending with a commit message:

Then you're not looking hard enough.

Every single patch description in the MFD subsystem starts with an
uppercase character, just as you would any sentence.

Oh, I see. I didn't notice the difference indeed. Thanks a lot for
the clarification.
