yes. it's correct.

The datasheet about the clock tells us the parent of the apbh-dma is usdhc3.

I guess imx6q-dma-apbh is compatible with imx28-dma-apbh.  In that
case, you need something like below.

			compatible = "fsl,imx6q-dma-apbh", "imx28-dma-apbh";

Then you do not need to patch mxs-dma.c at all.

Shawn

As I commented on dts change, you do not need to patch
drivers/dma/mxs-dma.c at all, since the IP block on imx6q is compatible
with imx28 with no need of any tweaking.  All you need to do is put
imx28 compatible string at the end of imx6q one, and the driver will
simply work for imx6q.  That's the whole point of DT compatible
property.

Shawn
