Yeah I understand why you're renaming those, but choose:

a. You avoid renaming and add the rest as PWRAP_MT8135_XXXX; or
b. You make two commits, one for the rename (and explaining why) and one
    for introducing MT6589 support.

Your choice.

Why are you reordering stuff around? I don't understand.

If you have a reason, make sure it's a good one, and make a different commit
just for the reordering, because otherwise the diff for this one gets a bit
hard to read.
