Which New STM32 SoC is that ? Please add type/model/...

The commit message should describe what does this patch do, and why does 
it do so, something like:

"
Document support for STM32MP13xx. This SoC contains two instances of 
DWMAC 4.20 IP. Because this is <somehow special>, document <some 
difference>.
"

Why do you move the location of 'description'? It just increases the 
diff. My preference is description is either 1st or last and not in the 
middle.

Just minItems is needed.

I don't think it is worth a whole new example just for 1 property 
difference.
