We've used so far for the schemas the first compatible to introduce
that controller as the filename, we should be consistent here. In that
case that would be allwinner,sun8i-a23-ths.yaml

You need a maxItems here too

What about something like this:

Calibration data for the thermal sensor

I'm not sure we need a abbreviation here, calibration would be more
explicit

Those examples won't compile.

Emmm, I have some questions about this.
I added this information and it can be compiled.
