I'm a bit confused about the order you are suggesting. It may seem
counter-intuitive, but MT7986 was released before MT7981, the thermal
units found in both SoCs seems to be exactly identical.
Or are you suggesting to list MT7981 first to maintain alphabetical
order? Because in terms of precedence, MT7986 has been there first, and
hence I'd list 7986 first, followed by 7981, ie. the opposite of the
order you were suggesting.
