Inspired by the vendor kernel but adapted to the upstream thermal
driver version.

And what would those be in this case?

I've used the names that were suggested here:

It's always the ".tzone_name" member of svs_(socmodel)_banks.pdata, with -thermal
suffix (drivers/soc/mediatek/mtk-svs.c).

Making it shorter for you....
performance CPUs:            cpu-big-thermal
low-power CPUs:              cpu-little-thermal
Cache Coherent Interconnect: cci-thermal
...and GPU is obviously      gpu-thermal

Cheers,
Angelo
