Sorry, but I strongly object to the argument of "DTs are not stable anyways, so we might just continue to break them". We are trying to keep them stable. I think you are referring to the GPC interrupt domain change with your above statement about DT stability breaking on 4.1/4.2. This is not the case. While I only catched the boot regression in the -rc phase of this kernel, the final released kernel will boot just fine with an old DTB. The i.MX platform tries to keep DTs stable. No exceptions.
