You're not actually using the mt8195-power and thermal includes.

Can you name this label lvts_ap, and the one below lvts_mcu, please? Makes it
much more readable.

Don't you need the reg size to be 0x1000 to be able to access THERMINTST in the
soc_temp_lvts.c?

Please drop all these '/* milliseconds */' comments. The thermal-zones
dt-binding already defines both of these properties as being in milliseconds, so
this is just polluting the DT.
