[PATCH v1 5/5] ARM: mxs: add mxs dma dt support
Dong Aisheng

Tue Mar 13 19:47:08 EST 2012
From: Dong Aisheng <dong.aisheng at linaro.org>
Originally the dma device will be added by default via
arch_initcall(mxs_add_mxs_dma);
Now change to call it explicitly in board file to avoid conflict
with device tree support.
