OK, then from now on I will NOT assume anymore that the reference code
also works on Meson6 platforms. Thanks for clarifying this.

I can test it on GXBB (only, I do not have Meson8b hardware, but
according to the datasheet the registers are the same).
If you want I can start based on your patch series. Should we add only
a binding for amlogic,meson8b and re-use that in meson-gxbb.dtsi or
should we add both (8b and gxbb) bindings instead?

sounds like this is what other devs are using as well - thanks for
letting me know
