Well, mostly... but not all of it.

The LCD, RTC and CAN require bindings/drivers work.

I think, I was too optimistic about 3.19, but we can try.
Since drivers will require adaptation, I'm not sure
it will be merged for 3.19...
If we really want to make the DT boot for 3.19, we could work and
post the drivers adaptation patches and in parallel (to keep thing
going for board files removal) prepare patches for adding the
problematic stuff via quirks. This way we can keep only the DT missing
functionality in quirks and remove the board files. Once the drivers
are adjusted with new bindings, we can remove the quirks.

Or if we are fine with keeping the board files for a little more, then
just add the DT functionality that is ready and keep working on drivers
until they are ready (hopefully, 1 - 2 releases).

What do you think?
