I've pushed this series to dt-for-next:
https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux.git/log/?h=dt-for-next

There's a minor conflict with dt-fixes as that branch deletes a property
from the pcie dt node which is moved in this series. I deleted the
property as I moved it in this series so the fix will be to take the
version in dt-for-next instead.
