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,
