Maybe tell us that this is for Android?

No the driver was merged with tristate.
See
commit a3fe1324c3c5c292ec79bd756497c1c44ff247d2 (tag: pinctrl-v6.17-1)

So that should be squashed into one patch or it will not bisect.

So why do we change this only for MT8189 and not for all
Mediatek pinctrl drivers?

I would just add this tristate option and license to all of them while
you're at it or I will get like 20 identical patches and it's a waste
of time for me.
