In our upcoming devboard (HSDK, see http://lists.infradead.org/pipermail/linux-snps-arc/2017-July/002667.html) we do use 2 slots of DW MobileStorage controller (even though it's not yet mentioned in its .dts). So the question is if multi-slot support gets removed from dwmmc driver or it's just a .dts option gets obsoleted. In latter case I'm wondering how to enable a second slot in dwmmc driver (will it just auto-probe it etc)? -Alexey
