The patches I have here do it all in the core per host with common bindings. I hope to post them tonight. They should fit the at91 model just fine as well, since they do each slot as a mmc_host, not as a separate slot with a shared host controller. (Some drivers don't seem to call mmc_of_parse(), which they will need to do to take advantage of the common implementation. But that can be addressed driver by driver as someone has a chance to test it). -Olof -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
