True, overlooked that one.

This is actually added by an earlier patch within this series (5/7),
but since it isn't used anywhere yet, might as well drop it for now,
"mediatek,mtu3" by itself works.

Also added by an earlier patch within the series (6/7), and also not
used anywhere yet.

That was in an earlier revision and removed (because the binding
description wasn't merged yet). Can add it of course (but then
mediatek,mt8365-uart and friends should probably stay as well).

I'll post a new revision adding it back (along with the binding
description) and add the binding description for mt8365-uart as well
(getting it to the same place mediatek,mt8365-mtu3 and
mediatek,mt8365-xhci are now).
Let me know if you'd prefer a variant that drops mediatek,mt8365-uart,
mediatek,mt8365-mtu3, mediatek,mt8365-xhci and doesn't bring back
mediatek,mt8365-systimer -- either one works for me, the fallbacks are
sufficient to make it work.
