"mfd"? That was an odd place for storing the tmio mmc specific platform data.

So, we need an ack for the mfd maintainer on this one as well. Lee,
can you have a look?

Future wise, I would also suggest the include/linux/mfd/tmio.h to be
split up in proper pieces.

This isn't needed, right?

Do you really need to invent new platform callbacks for this? Wouldn't
it be possible to let the driver handle the quirk by itself?
