Any plans to add DMA support for mxs-auart serial driver? I noticed
it is impossible to archive full 3.25 Mbs speed with current one.

No plans from our side, currently.

OK, AUART works fine with 115200 bps but over that it loose data 
randomly. I have seen fifo overrun errors during receiving data with 
1Mbs and over. So current driver is unuseful with higher baud rates.
