Thanks Jaehoon! I have pulled it into my next branch.

I think it's fine if you just stay on top of my next branch. If you at any point see that dw_mmc has a dependency to a new rc, then just tell me and I will rebase my next branch on that.

One more minor thing, I suggest you to add your sob tag for each patch and not the ack. Some of the patches had both.

Again, thanks for helping out!

Kind regards
Uffe
