Hi,

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.

There is DMA supported driver on freescale's git tree:
http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=blob;f=drivers/serial/mxs-auart.c;hb=imx_2.6.35_11.09.01

As I understood porting DMA support from freescale's driver is not 
trivial because MXS DMA implementation has been changed to mainline version.
