Yeah but we basically regressed the ux500 with the patch now
queued for v3.13:
commit 49c129519a7a8840767321c38d2eaf84a263529b
"ARM: ux500: Stop passing MMC's platform data for Device Tree boots"

Which deleted the passing of this non-yet-DT:ed platform
data.

Since it's a regression we need to do a fixup patch for the
v3.13 series adding it back.

Since this patch probably needs to be rewritten on top of
that I don't merge this patch as of now.

Yours,
Linus Walleij
