Perhaps we shouldn't try to script legal advice.

At least for the DT bindings, we probably want those to be Apache v2
because that's what the DT spec is. But that really only matters on
the common bindings. But then are device specific bindings derived
from those? And we have include/dt-bindings/ which are part of binding
definition/doc and those get used in dts (GPL, MIT or BSD) and source
files. In summary, it's complicated...
