I suspect the same thing will be happening for a lot of platforms
after 3.7-rc1: ux500, lpc32xx, integrator, imx, mxs and probably
others are all waiting for this so they can complete the move
to DT-only booting.
Having some support for the new binding in 3.7 would be a great
help to reduce interdependencies for the 3.8 merge cycle. Both the
driver interface and the binding should actually be in a good
shape now, so I'd very much appriciate it getting merged for 3.7,
even if the implementation may have to change again in 3.8.
