Now would it make sense to NOT merge these changes for 3.7 and postpone to 3.8. I can host these patches on a topic branch and merge them when we are ready. I plan to spend some good amount of time on my work this week so we should be ready pretty soon. One these changes are merged, users can start moving to this scheme.FWIW, I'm already basing the EDMA dmaengine support for OMAP (specifically for AM335x) on using these helpers since AM335x only boots from DT.
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.
