I appreciate the offer to take over your patch set to move things forward. However, I feel I must respectfully decline. This is mainly due to my lack of experience with both upstream kernel development on this hardware and the patch management process itself. It would be irresponsible of me to take on something that I'm not knowledgeable enough to ensure successful completion. I'm happy to work with you to help in any other way that I can such as testing patches, but I think you should maintain ownership of the patch-set and submission process, at least for now. One of the reasons I withdrew my own patch-set is that from what I can see your series covers everything I was trying to achieve, and does it correctly :-) The only one that isn't covered is the patch for early TCS initialisation that I'm discussing with Konrad which may be unnecessary anyway.
