This series intends mostly to enable support for ARM64 architecture
in the rockchip-iommu driver. On the way to do so, some bugs are also
fixed.
The most important changes here are:
- making the Rockchip IOMMU driver use DMA API for managing cache
coherency of page tables,
- making the Rockchip DRM driver not use DMA API on behalf of a virtual
device (behind a virtual IOMMU) to allocate and map buffers, but
instead proper DRM helpers and IOMMU API directly.
Changes since v4:
- Address some coding style comments on:
- https://chromium-review.googlesource.com/#/c/346328/38
- https://chromium-review.googlesource.com/#/c/353591/10
Changes since v3:
- Drop the idea of virtual IOMMU. Instead replace hacky allocation code
in DRM driver, with proper management of IOMMU domain.
- Add one more fix for allocation of IOMMU register base addresses.
Changes since v2:
- Instead of registering virtual IOMMU from DTS, create it when
attaching.
- Fix some bugs found in internal review.
