From a09820043c9e11149145a1ec221eed4a7b42dcce Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 21 Sep 2012 15:05:48 +0300 Subject: dw_dmac: autoconfigure data_width or get it via platform data Not all of the controllers support the 64 bit data width. Make it configurable via platform data. The driver will try to get a value from the component parameters, otherwise it will use the platform data.
