Hm, so we have mediatek,mt8365-infracfg defined in mt8365-sys-clock. Also the 
description talks about infracfg_ao. You now introduce INFRACFG-NAO. Is that 
just another system clock block, or is this covered with the 
mediatek,mt8365-infracfg binding?

We would need to clean that up.

Regards,
Matthias

Looking through the datasheet I don't see any clock related registers
for infracfg-nao. So I don't think it is another system clock block. It
seems to be a lot of status registers and debug registers, but not all
of them. It really doesn't seem to have a specific topic here. So from
my point of view it is just a syscon block. Should I add a
mediatek,mt8365-infracfg-nao compatible to the syscon binding
documentation?

Thanks,
Markus
