I reworked the patch to use the same codeflow as the Ux500/ST variant and posted my patches, but still no luck (hope it helps though, and just wanted to illustrate how I think the final patch should look). Are you sure the MMCI derivates on the APQ8060 and MSM8660 has this extra "PROGDONE" bit?

This problem seems SD600c-specific. Yours, Linus Walleij
