I wonder how to proceed now... Are you planning to continue inserting my
remaining snow/smdk/arndale refactoring patches [1,2,3,4] before the mmc
slot node refactoring on v3.18-next/dt-samsung branch?
I.e., should I send out a v7 rebasing either the remainder or just
Spring on top of your for-next, or should I just post new follow-up
patches to this series and wait?

I've prepared and successfully tested a patch adding the pinctrl Doug
requested above. Additionally, I have another follow-up ready, adding a
gmt,g781 temperature sensor (with v3.17-rc1 that actually works).

Also I understood that Javier is waiting for my remaining Snow bits to
be applied before sending out further Snow DT cleanups/fixes of his.
