I'll also highlight there's a DT only tree[1] available to import DT
related parts to other projects. It's generated from the kernel tree.
Probably an overkill to copying at this point though.

This actually brings up something else: do we want (eventually) *all* 
Apple boards using these SoCs to have up-to-date devicetrees in the 
Linux kernel tree? Obviously not every device supported by mainline has 
proper ones in, but I don't know if that's expected or something to be 
avoided.

If this is intended to be kept in sync and be fully comprehensive, I 
might as well start planning out our longer term DT maintenance strategy 
around that (which might involve using that tree in our bootloader).
