[PATCH 0/5] iommu/sun50i: Fix various issues

[Jernej Skrabec]

Testing IOMMU together with video decoder (Cedrus) exposed many bugs in
sun50i-iommu driver. This series addresses all issues so video decoder
works well with IOMMU.

First two patches address recovery issues in interrupt when either page
faults or permission errors were reported. Third patch fixes permission
domain assignment. Fourth patch fixes dma sync size. Sometimes sync also
touched some other buffers and kernel generated warning in dmesg. Fifth
patch fixes issue with synching PDE and PTE tables. Without it, page
faults were randomly generated even with valid iova addresses.

Please take a look.

Best regards,
Jernej
