From: Chaoyi Chen <[email protected]> On the RK3506 platform, there is no iommu hardware. And even on platform that have iommu hardware, it should be possible to use VOP without enabling iommu. In this case, a contiguous memory space like CMA should be used.
So this patch removes the dependency on ROCKCHIP_IOMMU.
