That's not an accurate description, this patch only adjust settings for
herobrine based boards. This should be reflected at list in the subject.
Besides setting the drive strengths this patch also disables the pulls
on some lines, so maybe better say something like "arm64: dts: qcom:
sc7280: herobrine: Add pinconf settings for mi2s1".
