Since enabling DMA Engine still keeps PIO support around I wonder why we need this Kconfig at all - other drivers seem to get by without this kind of thing? So in my opinion it would also be nice to get rid of SERIAL_SH_SCI_DMA completely and reducing the number of special per-driver Kconfig entries. Cheers, / magnus
