Also "address" should be "vaddr". With that fixed imx_v7_defconfig compiles successfully and from what I can tell also works. I haven't looked into this patch yet. Passing a struct device to the dma_sync functions is a step into the right direction for sure. Ultimately both patches should be merged to avoid bisecting failures.
