The mmc core, mmc host drivers and even an sdio func driver that is abusing the mmc host interface... I guess patches will show what you have in mind. :-) Kind regards Uffe -- 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
