Is there? There is some in-tree stuff, but haven't seen any other
sign of patches.

Having looked a bit at that I get the impression that this DT code has
been developed (by Grant I guess) in QEMU only as a proof of concept,
and never really tested on a real Versatile hardware unit.

These:
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7390/1
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7391/1

make it clear that noone ever tested an MMC card on a Versatile
booted on real hardware using DT. And I strongly suspect there
are more instances like that, it seems AACI, GPIO and I2C and
I guess whatever you cannot test on QEMU is just unsupported.

But maybe the majority of Versatile users are on QEMU anyway,
I sometimes get that impression :-/

Yours,
