This series patches mainly for ARM64 supporting. To do this, it first add virtual iommu slave device which DRM can attach to, convert DRM driver to use common iommu API instead of the ARM32 functions, and then use DMA API in iommu driver to map, to flush cache.
The v2 patches make a lot changes vs v1, so please forget the v1.
