No need to keep my signoff here: if you are posting the patch, your
signoff should come last. (Authorship is no factor here, only the path
taken by the patch from the author/copyright holder to the sender of
the email)

We should add the following property here:
- dma-coherent: Boolean property, must only be present if memory
accesses performed by the device are cache coherent
(I only added support for this in our platform earlier this week)
