No. Read that email again. What Benoit said was that if Felipe was fine
with the change _HE_ would take it. Huge difference, and one that would have
avoided this situation.

The only way to solve these things in the future is to make the driver handle
both the new and the old binding. Bindings are not supposed to change in
incompatible ways any more, unless for special circumstances and/or when the
old binding was completely broken.


The only way forward here, since Greg runs a stable tree that he doesn't
rebase, is for us to rebuild without the OMAP DT branch, and ask Benoit to take
out the conflicting changes.

Benoit, I know this is none of your fault, but would you mind preparing a new
copy of the DT branch without the conflicting patches, and hold those to 3.13?
I haven't looked to see how many those were.
