AFAIK the SDHOST controller isn't able to handle SDIO. Maybe we should mention this in the binding document.

The binding should be documentation of the binding.  I'd love to see
more explanation in the mmc/host/bcm2835.c, though.

Updated both mmc/host/bcm2835.c comment and Kconfig entry now.

cheers,
