Especially since we will soon have an API for how to set the I/O voltages - and the intelligence within that API is not something we would like to implement for each and every host driver. https://lkml.org/lkml/2015/8/31/367 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
