I don't normally (yet) ask for schema conversions on compatible 
additions, but this is one of the few remaining compatibles with no 
schema for allwinner. So a conversion here would be nice. BTW, dtschema 
now has a better check for this (-m option) without the false positives. 
I plan to turn on the option soon (doesn't matter for dtbs as they all 
have lots of warnings, but bindings also get warnings).

Either way,
