David, I don't see you point here.

IMHO, /delete-node/ and /delete-property/ keywords present in a dts
apply to the generated dtb.

A dts with /delete-*/ will generate a dtb with related node/property
deleted.

A dtso with /delete-*/ will generate a dtbo with related node/property
deleted.

David, I don't see why resolution is (or should be) involved here.

Best regards,
Hervé
