Date: Fri, 13 Jul 2012 11:09:34 +0300 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: Viresh Kumar <viresh.linux@...il.com>, linux-kernel@...r.kernel.org, Vinod Koul <vinod.koul@...el.com>, Dan Williams <dan.j.williams@...el.com> Cc: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH 3/3] dw_dmac: set default alignment The default values are filled to support at least mem-to-mem tests provided by dmatest module. It makes sense to choose the 4 bytes (2 least significant bits) alignment by the default.
