The big issue with this is apple does not own all of the IP in a any of their hardware, much of it is a mixture of licenses from many vendors some of it owned by apple much of it just licensed. Apples licenses for these will include very strict NDA clauses that make it impossible for apple to share the documentation they are provided but that vendor.
