Hi Tomasz,
Thanks for the review!
Considering where things currently stand, I thing getting the three first
patches merged in the near future would make sense. The rest will need a bit
more work, and adding buffer flags that aren't used wouldn't really make
sense either. See below.

Patch ccc66e73 ("ARM: 8508/2: videobuf2-dc: Let drivers specify DMA
attrs") added support for driver specific DMA attributes to
videobuf2-dma-contig but it had several issues in it.
In particular,
- cache operations were only performed on USERPTR buffers,
- DMA attributes were set only for MMAP
