I'm concerned that this patch hasn't been picked up for 3.17 (I can't see it
in -next). If we want to move the ARM SMMU driver over to this new binding,
we can't keep dragging our feet for much longer as I *really* don't plan to
support two bindings in parallel (one is complicated enough already).
Any chance we can see this merged, please?
Will
