Subject: mxs-auart serial driver DMA support?
Date: Thu, 12 Jan 2012 08:30:31 +0200 [thread overview]
Message-ID: <4F0E7E07.1020306@bluegiga.com> (raw)
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.
Regards,
Lauri Hintsala
