Don't you want/need to relicense "everything" in include/dt/ > and arch/*/boot/dts/? There are only a few header files in include/dt-bindings/ suppose to be generic. The irq related ones are the only files we used. Maybe it will be helpful to have the generic headers dual licensed too. But I think the license used for the arch/*/boot/dts/ files should be decided by the hardware vendor/copyright holders themselves. Regards, Leo
