Neither seems to actually ever have been used with more than one slot. I doubt anyone building an exynos-based system will ever do a multi-slot solution, and it seems that the at91 driver doesn't actually handle more than one slot. I'm personally not that excited about complicating the bindings by opening up for this -- I would rather work towards removing the concept of slots if it's one of those things that are going to remain unused. We have actually been talking about reworking the dw_mmc binding to remove the slot concept (and simplify the driver by doing so). -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
